Definitions
- the invention relates to a method and a device for applying a two-component impregnating or coating agent to a carrier.
- a two-component impregnating or coating agent to a carrier.
- a carrier such as plastic, sheet metal, fabrics or glass fibers.
- the two-component agent can either be used for impregnation, especially for strengthening and filling the fiber structure, or also for impregnation and / or subsequent coating. Both sheets, such as sheets or strips, and fiber bundles can be impregnated and / or coated.
- Such supports to be coated and / or impregnated can thus have any geometric shapes.
- two-component agents are also to be understood as mixtures with several components. This can involve several cross-linkable polymers or the use of different hardeners in one system. Mixtures in which, for example, a thermoplastic curing or a solvent-containing and drying system additionally contains at least one polymerizable polymer or prepolymer and a corresponding hardener system or crosslinking agent.
- Epoxy resins have proven particularly useful as coating and / or impregnating agents, as in US Pat. No. 5,478,599 and - 2 -
- EP patent 476 752 described in detail.
- epoxy resins are e.g. available under the name Epon Resin 1031 from Shell Chemical Company.
- a suitable hardener is used as the second component in such two-component systems. These mainly include amines, acids, phenols and anhydrides. Novolac hardeners, such as those used e.g. under the name Epikur DX-175 from Shell International Company.
- curing accelerators are often used to accelerate curing / crosslinking and / or to lower the curing temperature.
- the polymer formulation can be adjusted so that the polymer resin becomes liquid at a predetermined temperature and can be applied in the liquid state in such a way that it is e.g. penetrates as deeply as possible into the substrate.
- the temperature setting of the hardener which is also liquefied by heating and then applied.
- the application temperature can be selected between 50 ° C. and 250 ° C., preferably between 100 ° C. and 200 ° C., depending on the setting of the resin and the hardener.
- the coated or impregnated support is then heated either at an elevated ambient temperature (for example by warm air) or by IR radiation.
- the polymer hardens in a temperature range between 80 ° C and 250 ° C, preferably between 120 ° C and 180 ° C, so that no gelation occurs.
- the coated carrier, in particular the fiber structure impregnated with polymer, can then be used 3 -
- curing treatment e.g. be subjected to a drying tower.
- the application of the two-component impregnating or coating agent causes problems.
- the two components are usually supplied in separate lines and brought together in a mixing head shortly before application to the carrier. Every interruption in the application process tends to cause the system in the application head to harden. This can result in business interruptions.
- the hardener and polymer generally have different viscosities at the same temperature. If both components are brought together in one application head, this leads to an adjustment of the temperature. As a rule, the desired optimal viscosity conditions of the two components cannot be set in this way. Optimizing the viscosity is an important process parameter simply because it enables penetration into the carrier during impregnation or bubble-free contact with the surface of the carrier.
- the invention is based on the object of improving the known methods and devices and of avoiding the disadvantages of the known.
- a method and a device are to be created in which bubble-free and full-surface penetration and wetting of the carrier material with the two-component agent is ensured.
- the curing conditions should be checked and shifted to a point that is freely determinable in terms of process and apparatus after the two components have been applied.
- the two components are applied to the carrier, preferably in succession and in separate, superimposed layers, and are first mixed on the carrier and then cured.
- the intimate mixing on the carrier means that the point in time at which hardening begins can be determined exactly.
- the system can be set so that it reacts immediately when mixed, while such settings must be avoided when premixing in order heads.
- the two components can therefore be applied separately. In certain applications, however, it is also possible to apply the two components roughly premixed and only then to mix them intimately on the carrier.
- thermoplastic or liquid components a two-component impregnating or coating agent is provided with thermoplastic or liquid components. Liquefaction usually takes place by heating in the temperature range described at the beginning.
- the two components are then applied to the carrier as separate, superimposed layers. It is therefore possible to arrange separate application devices with application parameters that are specifically geared to the component applied in each case. In the case of impregnation of a fiber structure, the applied component penetrates into the fiber structure.
- At least the first of the applied layers is advantageously solidified before the application of the second layer. This is done optimally simply by the layer cooling and solidifying in the process. This prevents the second applied layer from mixing with the first layer and the hardening process starting in an uncontrolled manner.
- the second layer will also cool down after application and harden in the process.
- this is not a mandatory procedural requirement.
- the solidified layer or layers is then liquefied again and mixed intimately with one another.
- This is expediently carried out by supplying thermal energy, for example in the form of infrared radiation from a radiant.
- the components can be mixed in an optimally simple manner by supplying ultrasound energy.
- an ultrasonic resonator emits heat in - 6 -
- resonators with a different oscillation frequency e.g. Use electromechanical resonators as a mixing head.
- Suitable ultrasound resonators for generating ultrasound energy have been in use for a wide variety of applications for many years.
- resonators are used for welding components, for cleaning or for separating and sieving.
- Suitable resonators are e.g. offered and distributed by the company Telsonic, Bronschhofen, Switzerland.
- the required output depends on the amount of the two-component agent applied, the conveying speed, the thickness and the weight of the carrier, as well as the possible pre-liquefaction of the components.
- the required power can be easily determined experimentally by bringing a coated carrier into contact with a resonator for the period of the process. The point at which optimal mixing of the two components occurs can be determined by slowly increasing the line. In addition, it can be observed with impregnation methods and devices at which power of the ultrasound resonator the two components optimally penetrate the carrier.
- the desired optimal temperature for the component can be set - 7 -
- the two components have different liquefaction temperatures.
- a hardener that melts at a higher temperature first. After application and penetration into the carrier, the hardener cools down and solidifies. If the polymer component is now applied with a lower melting temperature, the hardener with the higher melting temperature remains firm. No mixing occurs when the two components are applied to one another. The hardening takes place in the next step by liquefaction and intensive mixing, preferably in an ultrasound energy field.
- the softening temperature of the two components differs by at least 30 ° C., preferably by at least 50 ° C.
- the liquefaction and mixing process can be accelerated by heating the two components before applying ultrasound energy.
- ultrasonic energy can accelerate the hardening and control the process.
- the ultrasound resonator can also be used in general with thermoplastic, solvent-containing, heat-reactive or otherwise curable impregnating agents and not only with two-component systems.
- the resonator does not serve as a mixing head, but only for "liquefying” and intimately incorporating the agent into the web and for expelling air bubbles.

- the liquefied hardener penetrates the web 5, which is passed over a cooling device 10 in the further process.
- the cooling device 10 causes the hardener applied as the first layer 2 to cool, so that it solidifies. Depending on the ambient temperature and the length of the route, the cooling device 10 can also be omitted.
- the web 5 is fed via a deflection roller 11 and a roller 12 to a second slot die 13.
- the slot die 13 is fed through a second extruder 14 with an epoxy resin (Epon Resin 1031 from Shell Chemical Company) heated to about 90 ° C.
- Epsin 1031 from Shell Chemical Company
- the resin applied as the second component 3 forms a separate layer on the first layer 2 - 10 -
- the second wide slot nozzle 13 is followed by an infrared heating device 15, with which the web 5 and the two layers 2 and 3 are heated.
- a resonator 16 is then provided, which applies ultrasound energy to the web 5 and the two layers 2 and 3 in such a way that the components of the two layers 2 and 3 mix intimately with one another and the web 5 is filled homogeneously with the two-component agent .
- rollers 17 and 18 Connected to the resonator 16 are two rollers 17 and 18 which are arranged at an adjustable distance from one another and which control and adjust the thickness of the impregnated web 5.
- the material web is fed to a heating device 20 in order to control the curing of the two-component mixture in a controlled manner. Infrared radiants are particularly suitable for this.
- FIG. 3 shows the web 5, which is used in an embodiment according to Figure 2 as a carrier 1 in the different process stages A to D.
- stage B the web 5 is penetrated by the hardener.
- stage C the epoxy resin supplied from the wide slots 13 is applied as the second layer 3 to the hardener.
- stage D layers 2 and 3 (hardener and epoxy resin) are mixed and the web 5 is homogeneously impregnated with the two-component impregnating and coating agent.
- the resonator 16 according to FIG. 2 is arranged over the entire width of the material web 5 in such a way that the entire width is acted upon by ultrasound energy. Since the web of material according to the exemplary embodiment according to FIG. 2 is coated on its upper side with the layers 2 and 3 of the two components, the action by the resonator 16 not only causes the layers 2 and 3 to be mixed and heated Material web 5 ensured by the two-component agent. In the embodiment according to FIG.
- FIG. 6 it can be seen how the two-component impregnating or coating agent partially remaining on the top of the carrier 1 is mixed by a first resonator 16a and "liquefied" under the influence of the ultrasound energy in such a way that after passing through the first ultrasonic resonator 16a is fully absorbed by the material of the carrier 1.
- a second resonator 16b further improves the homogeneity and mixing of the material in the carrier 1.
- a fiber bundle 22 is used as the carrier 1, which is first passed around a roller 23 and is soaked in a heated impregnation trough 24 with the first component of a two-component agent.

- Resonator 16 applies such high ultrasound energy to the fiber bundle 22 that the two components are heated, liquefied and mixed at the same time.
- the mixing can also take place in two stages and with two resonators 16a and 16b analogously to FIG. 6.
- An electromagnetic oscillator or a vibrator driven in some other way can also be used as the mixing head as the resonator 16. With such vibrators, however, sufficient heat supply (e.g. by a radiant heater and / or hot air or by electrical heating) must be provided in front of the mixing head in order to sufficiently liquefy the two-component agent in front of the mixing head.
- the first impregnation trough 24 obviously remains unused.
- the device can be used both for two-component impregnating agents and for one-component impregnating agents.
