    [0001] The present invention relates to a sizing composition for insulating products based on mineral wool, in particular glass wool or rock wool, containing hydrogenated sugars, at least one polycarboxylic acid and a significant amount of at least one epoxysilane. The manufacture of insulating products based on mineral wool generally comprises a step of manufacturing the glass or rock fibers by a centrifugation process. On their path between the centrifuge device and the fiber collection belt, an aqueous sizing composition, also called binder, is vaporized on the still hot fibers, which is then subjected to a thermosetting reaction at temperatures of about 200 ° C. vs. Phenolic resins used for several decades as binders are being replaced more and more by products from renewable sources and emitting little or no formaldehyde, a compound considered to be harmful to human health. . It is thus known, for example from US 2011/0223364, to bind inorganic fibers with formaldehyde-free aqueous sizing compositions containing, as heat-crosslinkable reagents, carbohydrates and polycarboxylic acids. However, the sizing compositions based on reducing sugars have the disadvantage of giving rise to coloring reactions (caramelization, Maillard reaction) which make it difficult or impossible to obtain light-colored products. The Applicant has proposed in its applications WO 2010/029266 and WO 2013/014399 binders based, not reducing sugars, but hydrogenated sugars, also called sugar alcohols. These reagents have a considerably higher thermal stability than the reducing sugars and do not give rise to Maillard reactions and / or caramelization. - 2 - Mineral wool insulation products and this new generation of "green" binders, however, are relatively hygroscopic and retain less mechanical properties over time than more colorful products made with reducing sugars. To compensate for the loss of mechanical properties after a certain period of aging of these insulating products, it is generally necessary to increase the proportion of binder by about 10 to 20%, which not only increases the cost of the final product but also alters its reaction to fire. In the course of its research to improve the mechanical properties of insulating products based on mineral wool glued with "colorless" binders, that is to say made from hydrogenated sugars, the Applicant noted with surprise that certain compounds, known as coupling agents, lead to a dramatic improvement in the mechanical properties of the insulation products obtained, provided that they are used at concentrations higher than those necessary for their operation as coupling agent . It is widely known and very common to use functional silanes as coupling agents to improve the adhesion of organic materials to mineral surfaces such as glass. A functional silane generally comprises at least one, preferably two or three hydrolyzable alkoxysilyl functional groups, capable of reacting with the silanol groups on the surface of the glass, and at least one reactive functional group (oxirane, amine) carried by a non-hydrolysable organic group, bound to the silicon atom by an Si-C bond. This organic function is generally chosen so as to react with the organic phase. To obtain a satisfactory binder-glass coupling effect, it is generally sufficient to add less than 1% by weight (of dry matter) of coupling agent to the sizing composition. There are, of course, patent applications in the state of the art which envisage higher concentrations of coupling agent (see, for example, US 2011/0223364), but the examples and preferred embodiments generally mention concentrations close to 0.5%, which is certainly motivated by the relatively high cost of these compounds. The most used coupling agents are aminosilanes. They are relatively cheaper than epoxysilanes and have a chemical stability at neutral pH which makes it possible to prepare the sizing compositions well in advance. Epoxysilanes not only cost more than aminosilanes, but have the other disadvantage that the epoxy function hydrolyses quite rapidly in the presence of water, giving rise to a much less reactive diol. The present invention is based on the rather surprising finding that epoxysilanes, unlike aminosilanes, significantly improve the aging resistance of mineral wool-based insulation products and hydrogenated sugar-containing binders, when used in concentrations above about 2% by weight. The present invention therefore relates to an aqueous sizing composition for insulating products based on mineral wool, comprising (a) at least one carbohydrate chosen from reducing sugars, hydrogenated sugars and a mixture thereof, the proportion carbohydrate-containing sugars being between 25 and 100% by weight, (b) at least one monomeric polycarboxylic acid or a salt or anhydride thereof, (c) more than 2.0% by weight, referred to the sum of components (a) and (b) of at least one epoxysilane. The component (a) of the sizing composition according to the invention may consist solely of hydrogenated sugars and be free of reducing sugars. This embodiment is interesting because it leads to insulating products particularly poorly colored.
    [0002] The term "carbohydrate" here has a broader meaning than it does because it includes not only strict carbohydrates, ie reducing sugars or carbohydrates of the formula C n (H 2 O) p having at least an aldehyde or ketone group (reducing group), but also the products of hydrogenation of these carbohydrates where the aldehyde or ketone group has been reduced. By "hydrogenated sugar" is meant in the present invention all of the products resulting from the reduction of a saccharide selected from monosaccharides, disaccharides, oligosaccharides and polysaccharides and mixtures of these products. The hydrogenated sugar is preferably a hydrogenation product of a starch hydrolyzate. Starch hydrolysates are products obtained by enzymatic hydrolysis and / or starch acid. The degree of hydrolysis is generally characterized by the dextrose equivalent (DE), defined by the following relationship: number of disrupted glycosidic linkages DE = 100 x number of glycosidic linkages in the initial starch The preferred starch hydrolysates have, before the hydrogenation step, an DE of between 5 and 99, and advantageously between 10 and 80. The hydrogenation of the saccharide can be carried out by known methods operating under conditions of high hydrogen pressure and high temperature, the presence of a catalyst selected from groups IB, IIB, IVB, VI, VII and VIII of the periodic table of the elements, preferably in the group comprising nickel, platinum, palladium, cobalt, molybdenum and their mixtures. The preferred catalyst is Raney nickel. Hydrogenation converts sugar or the mixture of sugars (starch hydrolyzate) into polyols or sugar alcohols. As examples of hydrogenated sugars, mention may be made of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol and palatinitol. maltotritol and hydrogenation products of starch hydrolysates. The hydrogenation products of starch hydrolysates will preferably be used. Preferably, the hydrogenated sugar or the mixture of hydrogenated sugars consists predominantly, that is to say more than 50% by weight, of maltitol (hydrogenation product of maltose, glucose dimer resulting from enzymatic hydrolysis of starch).
    [0003] In another embodiment, component (a) may contain up to 75% by weight of one or more reducing sugars, in addition to the hydrogenated sugar (s). Insulating products based on mineral wool obtained with a sizing composition having a certain content of reducing sugars are relatively more colored, but may be of real economic interest related to the low cost of reducing sugars or incompletely hydrogenated sugar mixtures. The hydrogenated sugar content of the carbohydrate (component (a)) is preferably at least 30% by weight, in particular at least 50% by weight, and ideally at least 70% by weight.
    [0004] Reducing sugars include monosaccharides (monosaccharides) and osides (disaccharides, oligosaccharides and polysaccharides). As examples of monosaccharides, mention may be made of those comprising from 3 to 8 carbon atoms, preferably the aldoses and advantageously the aldoses containing 5 to 7 carbon atoms. The particularly preferred aldoses are natural aldoses (belonging to the D series), in particular hexoses such as glucose, mannose and galactose. Lactose or maltose are examples of disaccharides which can be used as reducing sugar. The polysaccharides which can be used for the present invention preferably have a weight average molecular weight of less than 100,000, preferably less than 50,000, advantageously less than 10,000. Preferably, the polysaccharide contains at least one unit chosen from the abovementioned aldoses, advantageously glucose. Especially preferred are reducing polysaccharides which consist predominantly (more than 50% by weight) of glucose units. The reducing sugar may especially be a mixture of monosaccharides, oligosaccharides and polysaccharides, especially a dextrine. Dextrins are compounds corresponding to the general formula (C6H10O5). They are obtained by partial hydrolysis of starch. Their DE is advantageously between 5 and 99, preferably between 10 and 80. The component (a), namely the carbohydrate consisting of hydrogenated sugars optionally mixed with reducing sugars, advantageously represents from 30 to 70% by weight, preferably from 40 to 60% by weight of solids of the sizing composition. Component (b) is a polycarboxylic acid monomer. It can be a dicarboxylic, tricarboxylic or tetracarboxylic acid. The dicarboxylic acids include, for example, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, malic acid, tartaric acid, tartronic acid, aspartic acid, glutamic acid, fumaric acid, itaconic acid, maleic acid, traumatic acid, camphoric acid, phthalic acid and its derivatives, in particular containing at least one boron or chlorine atom, tetrahydrophthalic acid and its derivatives, especially containing at least one chlorine atom such as chlorendic acid, isophthalic acid terephthalic acid, mesaconic acid and citraconic acid; Tricarboxylic acids include, for example, citric acid, tricarballylic acid, 1,2,4-butanetricarboxylic acid, aconitic acid, hemimellitic acid, trimellitic acid and trimesic acid; Tetracarboxylic acid, for example 1,2,3,4-butanetetracarboxylic acid and pyromellitic acid, may be mentioned. Citric acid is preferably used. Component (b), namely the monomeric polycarboxylic acid, is preferably 30 to 70% by weight, preferably 40 to 60% by weight solids of the sizing composition of the present invention. The weight ratio of component (a) to component (b) is preferably from 70/30 to 30/70, in particular from 60/40 to 40/60. As explained in the introduction, the presence of a high concentration of an epoxysilane is an essential technical feature of the present invention. The sizing composition of the present invention preferably contains from 2.1 to 7% by weight, preferably from 2.3 to 6% by weight and in particular from 2.5 to 5% by weight and ideally from 3 to 4% by weight. , 5% by weight of at least one epoxysilane, these percentages being expressed relative to the sum of components (a) and (b). The higher the epoxysilane content, the greater the anti-aging effect. The relatively high cost of the epoxysilanes, however, leads to limiting the amounts of epoxysilanes used. It is, however, likely that the increase in the cost price of the sizing composition, resulting from the use of large concentrations of an epoxysilane, will be offset by the possibility of using less sizing composition. The epoxysilanes of the present invention may be trialkoxysilanes or di-alkoxysilanes, i.e., they may comprise two or three alkoxy functions hydrolyzable to silanol functions. Trialkoxysilanes are particularly preferred. The alkoxy groups are preferably methoxy or ethoxy groups, methoxy groups, more reactive than ethoxy groups, being preferred. The epoxysilane used in the present invention for improving the aging resistance of mineral wool insulation products bound by hydrogenated sugar-based binders is advantageously selected from the group consisting of 3-glycidyloxypropyltrialkoxysilanes, 3-g lycidoxypropyl-dialkoxyalkylsilanes, epoxycyclohexylethyltrialkoxysilanes, epoxycyclohexylethyldialkoxyalkylsilanes. 3-g lycidyloxypropyl-trialkoxysilanes are particularly interesting and among these we have obtained excellent results with (3-glycidyloxypropyl) -trimethoxysilane, sold for example under the name GLYMO by the company Evonik, under the name Z-6040 by Dow Corning or under the reference OFS-6040 by Xiameter.
    [0005] The sizing composition may furthermore comprise a catalyst which may be chosen from Lewis bases and acids, such as clays, colloidal or non-colloidal silica, organic amines, quaternary ammoniums, metal oxides and metal sulphates. metal chlorides, urea sulphates, urea chlorides and silicate catalysts. The catalyst may also be a phosphorus-containing compound, for example an alkali metal hypophosphite, an alkali metal phosphite, an alkali metal polyphosphate, an alkali metal hydrogen phosphate, a phosphoric acid or an alkyl phosphonic acid. Preferably, the alkali metal is sodium or potassium. The catalyst may also be a compound containing fluorine and boron, for example tetrafluoroboric acid or a salt of this acid, especially an alkali metal tetrafluoroborate such as sodium or potassium, an alkaline earth metal tetrafluoroborate such as calcium or magnesium, zinc tetrafluoroborate and ammonium tetrafluoroborate. Preferably, the catalyst is sodium hypophosphite, sodium phosphite or a mixture of these compounds. The amount of catalyst introduced into the sizing composition is generally at most 20% by weight, preferably 1 to 10% by weight, based on the total weight of components (a) and (b). The sizing composition according to the invention may furthermore comprise the conventional additives hereafter in the following proportions calculated on the basis of 100 parts by weight of component (a) + (b): From 0 to 40 parts, preferably from 4 to 25 parts, an oil or oil emulsion, 0 to 5 parts of a hydrophobic agent, in particular a silicone, from 0 to 20 parts of a polyol other than hydrogenated sugars From 0 to 30 parts of urea, preferably 0 to 20 parts, from 0 to 30 parts of an extender extender chosen from lignin derivatives such as ammonium lignosulfonate (LSA) or sodium lignosulfonate, and animal or vegetable proteins. The role of the additives is known and briefly recalled: The oils are anti-dust agents and hydrophobic agents; the urea acts as a plasticizer and also makes it possible to adjust the gel time of the sizing composition in order to avoid the problems of pre-gelling; the extension charge is a soluble or dispersible organic filler in the sizing composition which makes it possible in particular to reduce the cost thereof. The hydrophobic agent is preferably a reactive silicone, that is to say a polydiorganosiloxane bearing at least one hydroxyl (silanol), carboxyl, anhydride, amine, epoxy or vinyl function capable of reacting with at least one of the constituents of the sizing composition and / or with the silanol groups of the glass surface. The reactive silicone is preferably liquid at room temperature. Its average molar mass is generally less than or equal to 50,000, preferably less than or equal to 10,000. Preferably, the reactive silicone comprises a reactive function, advantageously a silanol function, at each of its chain ends. The reactive function of the reactive silicone can be blocked by a protecting group which releases said reactive function under the effect of heat. The proportion of reactive silicone in the sizing composition generally varies from 0.1 to 5 parts, preferably from 0.3 to 3 parts, advantageously from 0.5 to 2.5 parts and better still from 0.7 to 1 part. , 8 parts by weight, per 100 parts by weight of the sum of components (a) and (b).
    [0006] The preparation of the sizing composition is carried out by simply mixing the aforementioned constituents with water. The sizing composition is intended to be applied to mineral fibers, especially glass or rock fibers. The present invention also relates to a method of manufacturing an insulating product based on mineral wool, comprising - the application of an aqueous sizing composition as described above on mineral wool fibers, and evaporation of the solvent phase of the aqueous sizing composition and thermal curing of the nonvolatile residue of the composition.
    [0007] In a conventional manner, the sizing composition is sprayed onto the mineral fibers at the outlet of the centrifugal device and before they are collected on the receiving member in the form of a sheet of fibers which is then treated at a temperature allowing crosslinking of the sizing and the formation of an infusible binder. The crosslinking of the sizing according to the invention is carried out at a temperature comparable to that of a formalin-phenolic resin, at a temperature greater than or equal to 110 ° C., preferably greater than or equal to 130 °, and advantageously greater than or equal to 130 ° C. or equal to 140 ° C. The high reactivity of the epoxysilane prevents the preparation of a sizing composition well in advance. In a preferred embodiment, the process of the present invention therefore comprises a step of preparing the aqueous sizing composition, carried out less than 24 hours, preferably less than 4 hours, in particular less than 1 hour, and ideally less than 15 minutes before the application step on the fibers, the epoxysilane being preferably mixed with the aqueous sizing composition containing all the other ingredients. The sizing composition advantageously has a pH of between 2 and 4, in particular between 2.5 and 3.5, ideally close to 3. The acoustic and / or thermal insulating products obtained by the process according to the invention from these glued fibers also constitute an object of the present invention. These products are generally in the form of a mattress or felt of mineral wool, glass or rock, or a veil ^ of mineral fibers, also glass or rock, intended in particular to form a surface coating of said mattress or felt. When the component (a) contains a very small proportion of reducing sugars, the products have a particularly advantageous white color.
    [0008] In addition, the insulating products have a high resistance to the development of microorganisms, especially molds, which is due to the non-fermentable nature of hydrogenated sugars. Example 1 Binder based on hydrogenated sugars Sizing compositions comprising the constituents in Table 1, expressed in weight parts, are prepared. The sizing compositions are prepared by introducing into a container water (about 80% of the final composition), hydrogenated sugar (maltitol syrup), citric acid, sodium hypophosphite (catalyst). , the emulsion of anti-dust oil, the silicone emulsion, and finally the epoxysilane (or comparative aminosilane) with vigorous stirring until complete dissolution of the constituents. Glass wool is produced by the internal centrifugation technique in which the molten glass composition is converted into fibers by means of a tool called "centrifugation plate" comprising a basket forming a chamber for receiving the melted composition and a peripheral band pierced with a multitude of orifices: the plate is rotated about its axis of symmetry arranged vertically, the composition is ejected through the orifices under the effect of the centrifugal force and the escaping material orifices are drawn into fibers with the assistance of a stream of drawing gas. Conventionally, a sizing spray crown is disposed below the fiberizing plate so as to evenly distribute the sizing composition on the glass wool just formed. The mineral wool thus bonded is collected on a belt conveyor equipped with internal suction boxes which hold the mineral wool in the form of a felt or a sheet on the surface of the conveyor. The conveyor then circulates in an oven maintained at 270 ° C where the components of the sizing polymerize to form a binder. The insulating product obtained has a nominal density equal to 17.5 kg / m3, a nominal thickness of about 75 mm and a loss on ignition of the order of 5%. The properties of the sizing compositions listed in the following Table 1 are evaluated in comparison with a conventional sizing composition containing a formalin-phenolic resin and urea (Reference) prepared according to Example 2, Test 1 of W001 / 96254 A1. The tensile strength is measured according to ASTM C 686-71T on a punched sample in the insulating product. The sample has the shape of a ring 122 mm long, 46 mm wide, a radius of curvature of the outside edge cut equal to 38 mm and a radius of curvature of the cut of the inner edge equal to 12, 5 mm. The sample is placed between two cylindrical chucks of a test machine, one of which is movable and moves at a constant speed. The tensile strength F of the sample is measured and the tensile strength RT, defined by the ratio of the breaking force F (in Newton) to the mass of the sample (in grams), is calculated. The tensile strength is measured immediately after manufacture (initial tensile strength) and after accelerated aging in an autoclave at a temperature of 105 ° C at 100% relative humidity for 15 minutes. The "thickness recovery" indicates the compressive elasticity of the final product. To measure it is applied, for a given time, a compression pressure such that the thickness is reduced to 1 / 4.8 of its initial value. After releasing this compression pressure, the thickness is again measured. Thickness recovery is the ratio of the thickness measured after releasing the compression pressure to the initial thickness. - 13 - Table 1 Sample 1 2 3 4 * Reference Phenolic resin R225 100 Hydrogenated sugar (Maltilite® 5575) 48 48 48 48 Citric acid 52 52 52 52 Sodium hypophosphite 5 5 5 5 Emulsion of anti-dust oil (HydroWax® 88) 9.5 9.5 9.5 9.5 9.5 Ammonium sulphate 3 Silicon emulsion (DC1581) 2.1 2.1 2.1 2.1 Aminosilane 0.5 0.5 Epoxysilane (GLYMOO) 0.5 1.5 3 RT ( in N / g) Before aging 4.5 4.3 4.5 5.0 5.0 After aging 2.9 3.1 3.6 4.2 4.4 Loss on fire 5.2 5.2 5, 2 5,2 4,7 Resumption of thickness (%) After 1 hour 108,106 106 107 After 30 days 98 97 96 96 102 * according to the invention It can be seen that the tensile strength of the sample 4 prepared in accordance with the invention has a tensile strength before aging equivalent to that of the reference sample, while all the comparative samples (No. 1 - 3) exhibit tensile strengths before aging that are at least 10% lower than those of the CH antillon of reference. Moreover, the loss of the tensile strength after aging is significantly lower for the sample according to the invention than for the three comparative samples. These results show that the use of a high concentration of an epoxysilane (3% GLYMO) makes it possible to significantly reduce the tensile strength loss of an insulation product prepared with a binder based solely on hydrogenated sugars. The value of the thickness recovery does not seem to depend on the concentration of the epoxysilane. Example 2 Binder based on hydrogenated sugars and reducing sugars The procedure is as described in Example 1 but using, as a carbohydrate, a mixture of a hydrogenated sugar (maltitol syrup) and a reducing sugar (glucose syrup). Table 2 specifies the weight fractions of the sizing compositions used and the mechanical properties of the mineral wool samples obtained.

As already noted in Example 1, the thickness recovery values of the final products seem to be independent of the chemical nature and the concentration of the silane.
