    technical field
    [001] The present invention relates to methods for preparing foam composite panels containing metallic cladding sheets.
    [002] Insulation panels are widely used to provide thermal insulation to homes, buildings, cold storage facilities, ships and other constructions. One type of insulation panel includes a polymeric foam core and sheet metal cladding panels. Constructions of this type can offer a good combination of thermal insulation, mechanical strength and fire resistance. For various reasons, it may be desirable to include fiber reinforcement in the polymeric foam layer. Fiber reinforcement can increase both the physical properties of the panel and its performance in fire tests.
    [003] Various processes can be used in the manufacture of insulation panels. Different processes are used depending on the type of coatings and core materials. It is well known to manufacture insulation panels in a simple continuous process when the faces are very thin and flexible materials. Continuous fabrication becomes more difficult when the panel includes two thicker metal cladding panels, especially when the polymer core also needs to be fiber reinforced. It is difficult to impregnate the fibrous reinforcement with the polymeric foam, expand the foam and apply the coating sheets in a single operation. Because of this, the fabrication of these panels is divided into separate fabrication processes. This increases equipment and operating costs. A more efficient and economical process is needed to manufacture these panels.
    [004] The present invention is a continuous process for preparing a foam laminate having metallic cladding sheets, comprising:
    [005] a) continuously feeding a lower metallic coating sheet that includes a metallic layer having a thickness of 0.2 to 1.0 mm on a moving surface;
    [006] b) continuously applying a fiber mat and a foamable curable resin composition on the mobile underside metal cladding sheet;
    [007] c) before fully expanding the foamable resin composition, continuously apply a layer of flexible barrier material on the top of the fiber mat and a foam-forming resin composition;
    [008] d) before fully expanding the foamable resin composition, continuously pass the lower metallic coating layer, fiber mat, resin composition and flexible barrier material through a constricted region to compress together the lower metallic coating layer, mat of fiber, resin composition and flexible barrier material, so that the resin composition is pushed into and impregnates the fiber mat and the flexible barrier material is contacted with the resin composition;
    [009] e) then continuously applying a layer of an adhesive layer on top of the layer of flexible barrier material;
    [010] f) then continuously apply a top (top) metallic coating sheet that includes a metallic layer with a thickness of 0.2 to 1.0 mm over the top of the adhesive layer, and
    [011] g) pass the resulting assembly through a double-band laminator to contact the upper metallic coating sheet with the adhesive layer, calibrate the assembly to a predetermined thickness and cure the resin composition, the adhesive layer, or both the composition of resin as the adhesive layer, to form the foam laminate.
    [012] This process allows the fabrication of insulation panels with two layers of metallic cladding and a fiber reinforced polymeric foam core, in a single continuous operation. The process allows for good impregnation of the fiber mat with the curable foamable resin composition, which leads to good fiber reinforcement of the polymeric foam layer and which, in turn, generates good mechanical properties. This process, therefore, requires less equipment, involves less operating costs, and produces a product with excellent thermal insulation capabilities and excellent fire resistance, as indicated by standardized fire tests.
    [013] The product of the inventive process is an insulation panel containing at least the following layers: a lower metallic coating sheet that includes a metallic layer with a thickness of 0.2 to 1.0 mm; a layer of polymeric foam reinforced through at least a portion of its thickness with a fiber mat, said layer of polymeric foam being adhered directly or indirectly to the lower metal sheet; a layer of flexible barrier material adhered to the fiber reinforced polymeric foam layer; an adhesive layer adhered to the layer of substantially flexible barrier material and an upper metallic coating sheet having a thickness of 0.2 to 1.0 mm adhered to the layer of flexible barrier material through the adhesive layer. Several optional layers can be inserted into the process, as described more fully below.
    [014] Figure 1 is a schematic drawing of an embodiment of the process of the invention.
    [015] Figure 2 is a cross-sectional view of an embodiment of an insulation panel produced according to the invention.
    [016] Figure 3 is a schematic drawing of an alternative embodiment of a part of the process of the invention.
    [017] Figure 4 is a schematic drawing of a second alternative embodiment of a part of the process of the invention.
    [018] Returning to Figure 1, a lower metallic coating sheet 2 is continuously fed to form a mobile lower coating sheet on which subsequently introduced materials are deposited. The lower metal cladding sheet 2 can be fed and moved using various types of mechanical equipment. For example, the metal cladding sheet 2 can be fed over a moving platform, such as an endless belt, a series of driven rollers, a draw/rack or other apparatus. The metallic cladding sheet 2 can be tensioned in the process through a double-band mill 11, or through some other downstream tensioning devices (not shown).
    [019] The fiber batt 10 and the foamable curable resin composition 19 are applied on the movable lower metal cladding sheet 2. In the embodiment shown, the resin composition 19 is deposited upstream of the fiber batt 10. However, as per shown in Figures 3 and 4, it is also possible to deposit the resin composition 19 downstream of the fiber batt 10. It is also possible to deposit the fiber batt 10 and the resin composition 19 at the same point in the process.
    [020] The fiber batt 10 can be deposited using any suitable equipment, including a series of rollers 16, as shown in Figure 1. Once deposited, the fiber batt 10 can be transported by the process through the sheath sheet metallic 2, or propelled and/or pulled by the process together with the metallic coating sheet 2.
    [021] The foamable curable resin composition 20 can be similarly deposited using a variety of types of dispensing equipment, including types known in the prior art. Appropriate equipment includes, for example, a transverse hose, one or more stationary mixing heads, one or more spray nozzles, or other apparatus suitable for dispensing a fluid. In Figure 1, such dispensing equipment is generally indicated by the reference symbol A. Equipment for depositing the foamable curable resin composition may also include various tanks or other containers for storing resin composition components, measuring means for measuring the components, and /or the formulated resin composition; mixing means for mixing the components and forming the resin composition, pumping means for transferring the components of the resin composition from their respective storage containers to and through the mixing means and/or through the dispensing apparatus. Appropriate equipment for mixing and dispensing the components of the foamable curable resin compositions are marketed, for example, by Cannon, SAIP and Krauss Maffei.
    [022] If desired, the resin composition dispensed can be formed into a layer and/or calibrated at this point in the process using equipment such as, for example, a set of compression rollers or a doctor blade ("doctor blade" ”).
    [023] Returning again to Figure 1, a layer of substantially non-porous flexible material 5 is continuously applied over the top of the fiber mat 10 and a resin composition 19. The flexible material 5 is applied before the resin composition 19 has if fully expanded. Resin composition 19 often begins to react and expand as soon as it is deposited, and it may be expanding, in some cases, even as it is being deposited. Consequently, the foamable resin composition 10 may already be partially expanded when the flexible material 5 is applied, as shown in Figure 1. Slower reacting resin compositions may not have expanded measurably yet at this point. In any case, the flexible material 5 must be deposited before the resin composition 19 has fully expanded.
    [024] The resulting assembly, including the lower metallic coating layer 2, the fiber mat 10, the resin composition 19 and the flexible material 5 is then continuously passed through the constricted region 14. This step is conducted before the composition of 19 foamable resin has fully expanded. The constricted region 14 has a height of at most and preferably slightly (such as 2 to 25%) less than the combined height of the various layers just before it enters the constricted region 14. Therefore, the lower metallic coating layer 2, a fiber mat 10, the resin composition 19 and the flexible material are compressed together in the constrained region 14. As the material passes through the constrained region 14, the resin composition 19 is pushed into the fiber mat 10, impregnating the mat. of fiber 10, and the lower lateral flexible material 5 is brought into contact with the resin composition 19.
    [025] In the embodiment shown in Figure 1, the constricted region 14 is defined by cylinders 12 and 13, which are separated by a predetermined distance which, in turn, defines the height of the constricted region 14.
    [026] The assembly egressing from the constricted region 14 includes layer 17 of fiber mat 10 impregnated with the resin composition 19 (which can be partially expanded). The layer 7 is sandwiched between the lower metallic coating layer 2 and the flexible material. Because the flexible material 5 acts as a barrier layer, the resin composition 19 is in contact with its lower surface, although it does not penetrate it and, for this reason, it does not contact the contact cylinder 12 or other mechanical device that defines the constricted region 14.
    [027] After the assembly leaves the constricted region 14, the adhesive layer 4 is continuously applied over the top of the flexible material 5. Various types of dispensing, mixing, measuring, spreading and/or calibrating equipment can be used to form the layer adhesive 4, including the types described above in connection with resin composition 19. In Figure 1, such dispensing equipment is generally indicated by the reference symbol B. Resin composition 19 may be unexpanded, partially expanded, or fully expanded at the point at that adhesive layer 4 is applied. In the embodiment shown in Figure 1, resin composition 19 is only partially expanded at the point where adhesive layer 4 is introduced.
    [028] Before applying the metallic top coating layer 1, the resin composition 19 can be at least partially expanded and/or partially cured. Partial curing can help the expanding resin composition support the weight of the top metal overlay sheet 1. The expansion can take place before, during and/or after the adhesive layer 4 is applied, as already described. Similarly, curing (which typically occurs concurrently with expansion, although it may partially follow the expansion step) can be conducted before, or preferably during or after, the application step of the adhesive layer 4. Very often, particularly when the resin composition 19 is based on isocyanate, the expansion gas generation and therefore the expansion step itself integrates the curing reaction and, in this case, occurs at least partially simultaneously with the curing step, although some reactions of additional cures can proceed after the blow gas has been generated and expansion is complete. It may not be necessary to completely cure the resin composition 19 before applying the top metal coating layer 1, if the partially cured and expanded resin composition 19 can support the weight of the top metal coating layer 1.
    [029] The top metallic coating sheet 1 is continuously applied on top of the adhesive layer 4. The way to release the top metallic coating layer 1 is not particularly critical. A wide range of mechanical devices can be used to apply the top metal cladding sheet 1, including any of those described in connection with the top metal cladding sheet 2.
    [030] If the top metallic overlay sheet 1 is profiled, the adhesive layer 4 can fill in the recessed areas of the overlay sheet to flatten its bottom surface.
    [031] The resulting assembly is then continuously passed through a double-band laminator 11 to contact the upper metallic coating sheet 1 with the adhesive layer 4, calibrate the assembly to a predetermined thickness and, if necessary, complete the cure of the resin composition 19 and/or the adhesive layer 4 to form a foam laminate 20. Upon curing, the resin composition 10 forms the polymeric foam layer 21, which is reinforced in at least part of its thickness by fiber mat 10. The gauge (i.e. the distance between the upper band 11a and the lower band 11b of the mill 11) defines the thickness of the panel. As the assembly passes through the laminator 11, the upper web 11a exerts a small downstream force on the upper metallic coating layer 1 by contacting it with the adhesive layer 1 and bonding it thereto. The foamed resin composition can be compressed somewhat at this stage, although the pressure should not be too high to collapse the foam or create high back pressure. If adhesive layer 4 and optional adhesive layer 6 (as described below) require thermal curing, it is preferable that such thermal curing occur at least partially during this lamination step, to bond the top metallic coating layer 4 to the reinforced foam layer 21. Heat may be applied across either or both surfaces, if necessary, to activate curing of resin composition 19 and/or adhesive layer 4.
    [032] The resulting laminate 20 is continuously expelled from the rear end of the dual band mill 11. The laminate 20 is then typically cut to any desired length (such as with knife 15, or preferably with a band saw or circular saw ), post-cured, if necessary or desirable, and packaged for storage and/or shipment/transport.
    [033] The upper metallic coating layer 1 and the lower metallic coating layer 2 are each single or multilayer materials, which include at least one metallic layer with a thickness of 0.2 to 1.0 mm. The metallic layer can be any metal that is solid at operating temperatures, although preferred metals for this purpose are steel, stainless steel, aluminum, nickel, zinc, titanium, bronze, copper, brass, magnesium and various alloys of any of these. Steel is most preferred due to its low cost and desirable mechanical properties. The metal layer can be flat, although it can also be profiled (eg grooved or ribbed along its length). The metallic layer can be surface treated, such as by corona discharge to improve its bondability with the adhesive layer 4. The metallic layer can also be heated prior to its introduction into the process of the invention. The profiling, surface treatment and/or heating steps can be integrated into the inventive process.
    [034] The metallic layer can be the only component of the metallic coating layers. Alternatively, either or both metallic coating layers can be laminates that contain one or more layers of other materials, such as, for example, paper, a protective coating, a paint, varnish/decorative layer, and the like. The upper metallic coating layer 1 and the lower metallic coating layer 2 can be the same or different from each other.
    [035] The fiber can be, for example, continuous aligned fibers; continuous streaks; short (15 cm or less in length) or long fibers randomly oriented. It is preferred that the fibers in the fiber batt are at least partially transported upwards as the foamable resin composition expands and cures, so that the fiber reinforcement expands through the entire thickness of the foam core layer formed when the resin composition forms. Therefore, although fiber batt fibers may, in some embodiments, be mechanically bonded (such as through interweaving, stitching and/or needling), thermally and/or adhesively bonded, spun or knitted, in a batt Preferred is the fibers preferably not thermally or adhesively joined, but at most being lightly interwoven, so that they move easily with each other and that at least some of them can be carried upward with the expansion of the resin composition. The fibers are preferably prepared with thermally stable material at the temperatures encountered during the panel fabrication process, being stiffer than the polymeric foam material. Fiberglass is a preferred type of fiber, although other types such as other ceramic materials (including mineral wool, boron nitride, silicon nitride, and the like), metal, carbon, high melting polymeric fibers, and fibers natural materials such as wool, cotton, jute, hemp or silk are useful. Fiberglass is preferred due to cost, availability and generally good performance. A preferred fiber mat can weigh, for example, from 20 to 80 g/m2. The fiber mat can be provided in the form of two or more stacked layers. The total thickness of the fiber mat(s) (before any expansion during curing of the resin composition) can be, for example, from 3 to 10 mm.
    [036] The foamable curable resin composition 10 is a mixture of polymeric precursors and blowing agents and/or blowing agent precursors that react in the process to produce a cellular polymeric foam. The foamable curable resin composition 19 is preferably formulated to produce a foam having a free growth density of from 16 to 320 kg/m3, more preferably from 24 to 80 kg/m3. The "free growth" density is determined by curing a sample of the resin composition without restricting its expansion vertically and in the absence of the fiber mat, and measuring the density of the foam so produced. The cellular polymeric foam thus produced is preferably a rigid foam.
    [037] Isocyanate-based resin compositions are highly preferred, as these compositions can be formulated to have low viscosity, which favors and facilitates penetration of the composition into the interstices between the fibers of the fiber mat, and also because the compositions Isocyanate based resins can be formulated to expand and cure, forming a polymeric foam with useful properties. Resin compositions based on isocyanate can be formulated to produce a polymer containing urethane groups, urea groups and/or isocyanurate groups. An especially preferred type of isocyanate-based resin composition is a polyisocyanurate or polyurethane-polyisocyanurate foaming composition, as foams of these types exhibit an excellent combination of high thermal insulation and excellent strength to weight ratio.
    [038] Appropriate isocyanate-based resin compositions are well known. Those described, for example, in WO 2010/114703 and WO 2007/02588 are suitable. In general, the isocyanate-based resin composition will include at least one polyisocyanate compound, at least one blowing agent, at least one polyol and at least one catalyst for reacting the isocyanate groups with themselves (to produce isocyanurate groups) and/or with materials reactive with isocyanate in the composition (such as polyols and any water that may be present).
    [039] The flexible barrier material layer prevents the foamable curable resin composition from contacting the equipment used to form the constricted region 14. It is therefore non-porous or, if it has pores or openings, these pores or openings are small or enough not to allow the foamable curable resin composition to penetrate the flexible barrier material during the process. By "flexible" it is meant that the composition and thickness of the sheet is such that the sheet can be reversibly bent to a radius of curvature of 1 inch (2.54 cm) or less, preferably 0.25 inch (6.25 cm). mm) or less, without permanent damage or distortion. The flexible material is preferably thermally stable under the process conditions of the invention and does not dissolve or degrade with the foamable curable resin composition.
    [040] A variety of materials are useful as flexible barrier material. Among these are paper; polymeric films and/or polymeric foams, including thermoplastic polymeric films and foams, such as polyolefin, polyester, poly(vinylidene chloride), polyamide, polycarbonate, polyurethane; metal sheets, such as aluminum foil, and the like; and fabrics and non-wovens. The flexible barrier material can be a multilayer structure containing two or more layers, at least one of which forms a barrier to the passage of the resin composition. For example, the flexible barrier material can include a porous layer bonded to a non-porous layer. An example of such a flexible barrier material includes a layer of a cellular polymer, granular material or fibrous material, or other porous material bonded to a non-porous layer such as paper sheet, a polymeric film layer or the like. A preferred type of flexible barrier material is a multilayer structure that includes a layer of fiberglass or other ceramic fiber bonded to one or both sides with a non-porous layer, such as paper or a polymeric film. An especially preferred type of flexible barrier material is a layer of mineral wool bonded to a layer of paper on one or both sides.
    [041] The layer of flexible barrier material can have a thickness, for example, of 20-100 mm.
    [042] The adhesive layer 4 can be, for example, a hot-melt adhesive or, preferably, a curable type, such as an epoxy adhesive or isocyanate-based adhesive. Suitable epoxy adhesives are well known and described, for example, in WO 2006/093949 and WO 2006/052726. These epoxy adhesives include an epoxy resin, a hardener and at least one epoxy cure catalyst. Suitable polyurethane and polyurethane-polyisocyanurate adhesives are also well known and described, for example, in WO 2011/045139. Polyurethane and polyurethane-polyisocyanurate adhesives include at least one polyisocyanate compound, at least one polyol, amino alcohol or polyamine, and preferably at least one catalyst for the curing reaction. If polyisocyanurate groups are to be formed, the adhesive preferably includes a catalyst for the trimerization of isocyanate groups, as well as a catalyst for the reaction of isocyanate groups with hydroxyl groups. An epoxy or polyurethane adhesive can be formulated as a one-part or two-part adhesive.
    [043] The adhesive layer 4 can contain an inorganic filler, which can be included to reduce costs, adjust its physical properties, provide a thermal barrier, provide additional flame retardancy and/or act as a swelling agent. Expandable graphite is an example of an inorganic filler that acts as a swelling agent. Adhesive layer 4 is preferably non-cellular and, if cellular, will have a density of at least 150 kg/m3, more preferably of at least 400 kg/m3, especially of at least 700 kg/m3.
    [044] Returning to Figure 2, the insulating panel 20 prepared according to the invention includes lower metallic coating layer 2, polymeric foam layer 21 (which is produced by expanding and curing resin composition 19 and reinforced with a blanket of fiber 10 in at least a part of its thickness), flexible layer 5, adhesive layer 4, and top metal coating layer 1. Adhesive layer 4 connects flexible layer 5 to top metal coating layer 1. Flexible layer 5 is directly attached to the polymeric foam layer. In the embodiment shown in Figure 2, the optional adhesive layer 6 connects the polymeric foam layer 21 to the lower metallic coating layer 2, although the adhesive layer 6 cannot be omitted, in which case the polymeric foam layer 21 is directly bonded to the lower metal cladding layer 2. Fiber mat 10 may extend a minimum of 10% and a maximum of 100% of the thickness of the polymeric foam layer 21, although preferably it extends for at least 50% of the thickness of the foam layer polymeric 21. For better illustration purposes, the thicknesses of the various layers are not to scale in Figure 2.
    [045] The insulation panel 20 preferably has a thickness of 25 to 250 mm. The reinforcing foam layer can have a thickness of 5 to 240 mm.
    [046] In some embodiments, an optional adhesive layer may be interposed between the lower metallic coating layer 2 and the reinforced foam layer 21. Such optional adhesive layer is indicated with reference number 6 in Figures 1, 3 and 4. Optional adhesive layer 6 can be, for example, a hot-melt adhesive or, preferably, a curable type such as an epoxy adhesive or an isocyanate-based adhesive, as described in relation to adhesive layer 4. If adhesive layer 6 is present, it can be the same or different from adhesive layer 4.
    [047] In the embodiment shown in Figure 1, the optional adhesive layer 6 is applied using the apparatus indicated by the reference symbol C, directly to the lower metallic coating layer 2, upstream of the point at which the resin composition 19 and fiber mat 10 are introduced. If the overlay metal sheet 1 is profiled, the adhesive layer 6 can fill in recessed areas of the overlay sheet to flatten the upper surface thereof. In alternative embodiments, the order in which the optional adhesive layer 6, fiber mat 10 and resin composition 19 are introduced may vary. Apparatus C is generally as described above with respect to apparatus A and B.
    [048] In the alternative embodiment shown in Figure 3, the optional adhesive layer 6 is applied to the lower metallic coating 2, and then the fiber mat 10 is applied directly on top of the optional adhesive layer 6, followed by the resin composition 19 and the flexible barrier material 5, before the materials pass through the constricted region 14 defined by cylinders 12 and 13.
    [049] In the alternative embodiment shown in Figure 4, the fiber mat 10 is placed directly over the lower metallic coating 2, followed by the optional adhesive layer 6, and then by the composition of resin 19 and flexible barrier material 5, before the materials pass through the constricted region 14 defined by cylinders 12 and 13.
    [050] In the alternative embodiments shown in Figures 3 and 4, the fiber mat 10 can be fully impregnated with adhesive layer 6, in addition to being partially impregnated by the resin composition 19. The adhesive 6 must be thinner than the fiber mat 10, so that at least a portion of the fiber mat 10 extends through the adhesive layer 6 and is impregnated with the resin composition 10, so that the resulting foam layer 21 is reinforced by the fiber mat 10 through at least one portion of its thickness, as described above.
    [051] The foam laminates of the invention can be used in a variety of structural insulation, thermal insulation and/or decorative applications. They can be used as building materials for internal and external walls, ceilings and roofing materials in buildings; with decorative and/or facade materials, duct system panels, walls and roofs in buildings; as insulating panels for buildings and various types of cold storage facilities. Laminates can be used as decks for ships/ships and other transport vehicles. These foam laminates can generally be used in the same applications and in the same way as conventional panels.
