    The present invention relates to a mixing device having the features of the preamble of claim 1 and a method for producing a foamed material having the features of the preamble of claim 13.
    With a generic method foamed materials can be produced using a generic mixing device, which have a variety of applications. For example, the foamed materials are seals.
    From DE 2 125 679 a device for mixing and ejecting liquid, after the mixture quickly curing, multi-component plastics is known. This device has a mixing chamber with a stirrer located therein. An outlet part of the mixing chamber is displaceably arranged against a restoring force in relation to a middle part of the mixing chamber. By material pressure in the interior of the mixing chamber Or by separate control, the outlet part is opened, after which the stirrer starts and verriihrt the newly entering the mixing chamber plastic material. After completion of an ejection process, the mixing chamber should remain completely filled with plastic in order to prevent air mixing and thus the mixing of the plastic material with air, as this would adversely affect the quality of the plastic parts to be produced.
    From EP 776 745 B1 a method has become known in which a viscous liquid is premixed with gas and then mixed in a mixing device with a curing agent (see Fig. 7 of this document). The problem is that it may come in the mixing device to outgassing of the gas from the viscous liquid, so that the mixture of the gas-mixed viscous liquid and the curing agent after expansion may not have the desired properties or even the expansion itself may be impaired ,
    From DE 1 779 667 A, a mixing device is known, in which a stirrer is formed in two parts, the two parts being biased towards one another by a spring, so that when a pressure prevailing in the mixing device is exceeded, the spring is compressed and the discharge opening is opened. This is to prevent dripping. It is not ensured that the pressure in the mixing device remains above that which reliably prevents the gas from foaming in the mixing device.
    The object of the invention is to provide a mixing device and a method in which the problems described above are avoided.
    This object is achieved by a mixing device having the features of claim 1 and a method having the features of claim 13.
    By the pressure holding device, it is possible to predetermine in the mixing device such a pressure that prevents outgassing of the gas from the at least one liquid and / or from the at least one liquid curing or crosslinking agent or from the mixture of liquid and curing Or crosslinking agent becomes. That predefinable pressure, in which a degassing of the gas from the at least one liquid and / or from the liquid curing or crosslinking agent is avoided, can be determined by experiments.
    Advantageous embodiments of the invention are defined in the dependent claims.
    The at least one liquid may preferably be a viscous liquid. Examples of the at least one liquid are polyols, silicones, epoxy, polyesters, acrylates and MS polymers.
    Examples of the gas with which the liquid and / or the liquid curing or crosslinking agent is mixed are air, nitrogen, carbon dioxide.
    An example of the curing agent is isocyanate.
    Examples of the crosslinking agent are silicones.
    Further examples of systems with at least two components are: addition-curing silicone with silicone as the liquid and silicone as addition-crosslinking crosslinking agent • condensation-cured silicone z.'B. with water and / or glycols, or according to DE 10 2008 011 986 A1 with silicone as a viscous liquid and water and / or glycols as a condensation-crosslinking crosslinking agent • polyurethane (result) crosslinked with isocyanate as curing agent. The polyol component as a liquid may, for. As polyester polyols, polyether polyols, thiols, glycols, amines, chain extenders and acrylates. The isocyanates may be aromatic (e.g., based on MDI, TDI) as well as aliphatic (e.g., based on HDI, IPDI, 12-fold hydrogenated MDI). • polyisocyanate, the second component contains the trimerization catalysts and possibly polyols, other active hydrogen substances or non-reactive thinners. • 1K NCO-terminated polyurethanes with water and / or glycols as curing or crosslinking agents (booster systems) • Epoxy resin systems • Silane-modified polymers with water and / or glycols in the B component, e.g. MS Polymers • Acrylates, radically cured • Unsaturated polyester resins, free radical cured • Vinylester resins, free radical cured
    The predeterminable by the pressure holding device pressure can be generated in the simplest case by a arranged in the region of the discharge opening aperture or a the accessible area of the discharge opening to a gap limiting solid antidote. The dimensioning of the aperture or gap required for a desired pressure can be determined by experiments or calculations.
    It is preferably provided that the presettable by the pressure holding device pressure by means of an adjustment changeable, preferably in stages or continuously adjustable. In this way, it is possible to react to different amounts of gas mixed with the liquid and / or the liquid hardening or crosslinking agent and to different discharge amounts from the discharge opening. But it may also be sufficient to set the pressure holding device once to a certain pressure, which is then no longer changed.

    As an alternative to variability via an egg visualization device, an exchangeable aperture for the dispensing aperture with different aperture diameters or an exchangeable nozzle connectable to the dispensing aperture and having different lengths and / or internal diameters can be provided.
    It is preferably provided that in the mixing device a movable relative to the discharge opening actuator is arranged, through which a gap remaining between the actuator and the discharge opening and thus the pressure generated by the pressure holding device are adjustable. Depending on the size of the gap, the pressure in the mixing device is different, wherein a smaller gap is associated with a higher pressure in the mixing device. In this embodiment, the pressure holding device is formed by the gap formed between the actuator and the discharge opening upon introduction of material into the mixing device.
    It is particularly preferred that the mixing device has a stirrer for mixing the at least one liquid and the at least one liquid curing or crosslinking agent. In this case, the mixing device may be referred to as a dynamic mixing device. If a stirrer is provided, the stirrer itself can be designed to be movable and form the actuator.
    It is preferably provided that the movable actuator is biased by a force storage in the direction of the discharge opening. In this way, it is possible to react independently to fluctuations in the viscosity of the mixture of liquid and curing or crosslinking agent and changes in the application rate such that the pressure in the mixing device remains substantially constant. The energy accumulator can be designed as a mechanical spring, as a compressed air spring, as a hydraulic piston-cylinder unit, as an additional mass loaded by the force of gravity, as an electric drive (for example a linear drive) or the like.
    Preferably, a device for adjusting the strength of the force accumulator is provided. In the case of a mechanical spring, for example, it may be an adjustable stop for the spring. In the case of the pneumatic spring or the hydraulic piston-cylinder unit, the pressure is directly adjustable.
    In the empty state of the mixing device, the energy accumulator is preferably dimensioned so that the discharge opening is closed by the actuator. As a result of the material introduced into the mixing device via the feed openings, the actuator is moved away from the discharge opening against the action of the force accumulator, forming a gap. The amount of movement away from the discharge opening is adjustable by the device for adjusting the strength of the energy storage device.
    Alternatively to the movable actuator can be provided that the discharge opening is movable relative to an axially fixed means, preferably a stirrer, for adjusting the gap remaining between the discharge opening and the axially fixed means. If the mixing device is elongated, it can be advantageous if the at least one feed opening for the at least one liquid and the at least one further feed opening for the at least one liquid hardening or crosslinking agent are arranged at different axial positions of the mixing device. Because the mixing of the liquid with the liquid curing or crosslinking agent takes place only in the region of that feed opening which is closer to the discharge opening, there is no or only little contamination in the axially overlying area.
    It can be provided that the discharge opening of the mixing device is connected to a nozzle.
    It can be provided that the gas is at least partially dissolved in the liquid and / or in the liquid curing or crosslinking agent.
    Contactor is also desired for an arrangement having a mixing device according to at least one of the preceding embodiments and a source for at least one liquid connected to the at least one feed opening for the at least one liquid, preferably the at least one liquid being mixed with a gas , and a source of at least one liquid curing or crosslinking agent associated with the at least one further supply port for the at least one liquid curing or crosslinking agent, preferably wherein the at least one liquid curing or crosslinking agent is mixed with a gas.
    Embodiments of the invention will be discussed with reference to the figures. Show it:
    1a to 1c, a first embodiment of a mixing device according to the invention with different variants in detail views,
    2 shows a second embodiment of an inventive
    Mixer,
    3a and 3b a stirrer with representation of forces acting on the stirrer,
    4 and 5 are detail views of further embodiments of proposed mixing devices.
    1a shows a mixing device 1 with a mixing chamber 12. A feed opening 2 for at least one gas-mixed viscous liquid (eg polyol mixed with air) and a further feed opening 3 for at least one liquid curing or crosslinking agent (eg isocyanate) are shown that lead into the mixing chamber 12. In this embodiment, the mixing device 1 is formed dynamically and comprises a stirrer 7, which is rotatable in the mixing chamber 12. Other than described, in addition to the liquid or instead of the liquid, the liquid curing or crosslinking agent can be mixed with a gas - e.g. Air - be mixed. Adjacent to the tip of the stirrer 7, a discharge opening 4 is provided, through which the mixture produced in the mixing chamber 12 from the at least one gas-mixed viscous liquid and the liquid curing or crosslinking agent in the direction of a nozzle 9 can be discharged.
    In the present embodiment, the pressure ratios are chosen so that it comes behind the discharge opening 4 to a decrease in the pressure of the mixture of the at least one gas-mixed viscous liquid and the liquid curing or crosslinking agent under those pressure at which it is to foam the gas in the mixture comes, so that it comes by an outgassing of the gas to an expansion and thus to a foaming of the mixture (physical foaming). ······ * ···
    The pressure-holding device is in this bélspiël gébilctet darch acted upon by a force accumulator 8 stirrer 7, which is arranged by a gap 6 spaced from the discharge opening 4.
    To produce the mixture of the at least one gas-blended viscous liquid and the liquid hardening or crosslinking agent, the gas-blended viscous liquid provided by a source 10 is passed through the first feed opening 2 and the liquid hardening or crosslinking agent is provided by a further source 11, introduced through the second feed opening 3 at different axial positions of the mixing device 1 formed here elongated here. By the rotating stirrer 7, it comes to mixing these two components.
    In the preferred embodiment shown here, the energy accumulator 8 is provided in the form of a spring which presses the agitator 7 against an end face 13 of the mixing chamber 12 having the discharge opening 4, until sufficient force has been provided by the material introduced via the sources 10 and 11 the agitator 7 is applied, so that it moves away from the end face 13 and thereby forms a gap 6 (here annular gap) between the end face 13 and the agitator 7, whereby the mixture produced in the mixing chamber 12 can escape from the discharge opening 4. The force applied by the force accumulator 8 in the direction of the discharge opening 4 is dimensioned so that the back pressure of the material mixture in the region of the gap 6 results in a pressure spreading across the mixing chamber 12, which results in outgassing of the gas from the mixture of the gas with the viscous liquid prevented.
    If there are fluctuations in backflow (eg as a result of varying application rate, fluctuating viscosity of the mixture, temperature fluctuations, fillers in the mixture, etc.), the position of the agitator 7 relative to the discharge opening 4 automatically adjusts, so that the pressure in the mixing chamber 12 is kept substantially constant. A seal 15 (which is shown here acting only in one direction, but can also act as a seal in both directions) sealingly encloses the rotating shaft 16 of the agitator 7 and seals the mixing chamber 12 in the region of the shaft 16 of the agitator 7. The seal 15 may for example consist of Teflon and allow smooth axial movement of the rotating shaft 16. The fact that the shaft 16 rotates and the seal 15 causes a low friction, a very fine axial position adjustment of the tube 7 can be achieved. In particular, unwanted pressure fluctuations due to jerky axial displacement of the stirrer 7 due to a stick-slip effect can thus be avoided. By the rotation deYWefle T6 VWfd also the axial displacement of the stirrer 7 is facilitated. Preferably, the seal 15 is formed as a rotational and translational seal.
    The bias of the energy accumulator 8 can be adjusted in the embodiment shown. In this example, a setting device 5 designed as a stop for the spring is provided in the form of a screw sleeve which is axially adjustable by a rotational movement.
    Other than illustrated, an embodiment is conceivable in which no energy storage 8 is provided and the gap 6 between the discharge opening 4 and the stirrer 7 is set fixed. In this embodiment, it is not possible to react to fluctuations in the backlog. Another, not shown embodiment could look like that, although an energy storage device 8 is provided, but this is structurally biased to a predetermined level. Again, no change can be made.
    1 b shows a detailed view of the tip of the stirrer 7, which in this example is sharper than the inclination of the end face 13 of the mixing chamber 12. As a result, the tip of the stirrer 7 rests only annularly on the end face 13 and protrudes into the discharge opening 4 in order to complete it annularly.
    Fig. 1c shows a variant of the embodiment, in which the energy accumulator 8 is designed as a compressed air spring. Furthermore, a variant is conceivable in which the energy accumulator 8 is designed as a hydraulic piston-cylinder unit.
    In contrast to FIGS. 1 a to 1 c, FIG. 2 shows an exemplary embodiment in which the stirrer 7 is not movably arranged in the mixing chamber 12, but the end wall of the mixing chamber 12, in whose end face 13 the discharge opening 4 is arranged, relative to the stirrer 7 can be moved to turn the gap 6 between discharge opening 4 and stirrer 7 set.
    All those variants which were shown for the embodiment according to FIG. 1a are also possible for the embodiment according to FIG.
    FIG. 3a shows a stirrer 7. The forces exerted on the stirrer 7 by the material introduced in the mixing chamber 12 (shown by arrows pointing to the stirrer 7) average up to the regions A1 (sealed region of the stirrer 7) and A2 (FIG. substantially unpressurized area through which the material from the discharge opening 4 can be discharged) away. The result is a pressure in the mixing chamber, which corresponds as much as possible to the force which is divided by the force separator by the difference between these two surfaces A1 and A2 (see FIG. 3b) ,
    FIG. 4 shows a further example of a pressure-maintaining device for a mixing device 1 according to FIG. 1 a. FIG. 5 shows a further example of a pressure-holding device for a mixing device 1 according to FIG. 2. In both cases the pressure-retaining device is provided by a diaphragm 14 and a stirrer 7 formed by a gap 6 spaced from the discharge opening 4 is formed. The presettable by this pressure holding device pressure can be generated in each case by the arranged in the region of the discharge opening 4 aperture 14. The required for the desired pressure sizing of the aperture 14 can be determined by experiments or calculations. This allows a particularly simple construction of the pressure-retaining device, in which, in particular, an adjusting device 5 can be dispensed with.
