Definitions
- Moldings and coatings made of natural and synthetic rubber are widely used in technology.
- a disadvantage of these materials is the relatively low resistance to aggressive chemicals, especially at higher temperatures.
- fluorothermoplastics in particular copolymers of tetrafluoroethylene with such amounts of comonomers that the product can be processed from the melt, for this purpose. But even these copolymers, which are closer to elastomers in their properties, do not adhere to rubbers.
- adhesion promoter a preparation made from the rubber and a thermoplastic or elastic fluoropolymer with a melting point ⁇ 250 ° C., hereinafter referred to as "adhesion promoter"
- the invention thus relates to a composition consisting essentially of a rubber and an adhesion promoter made of a thermoplastic or elastomeric fluoropolymer with a melting point ⁇ 250 "C.
- the adhesion promoter is a terpolymer made from tetrafluoroethylene, hexafluoropropene and vinylidene fluoride or from tetrafluoroethylene, hexafluoropropene and Ethylene or a copolymer of tetrafluoroethylene and propene.
- terpolymers of tetrafluoroethylene, hexfluoropropene and vinylidene fluoride have thermoplastic properties if they contain more than about 35% by weight of tetrafluoroethylene.
- Such terpolymers are known, for example, from US Pat. No. 4,335,238 and US Pat
- Suitable terpolymers contain from about 40 to about 60 percent by weight tetrafluoroethylene, from about 10 to about 40 percent by weight hexafluoropropene and from about 10 to about 40 percent by weight vinylidene fluoride.
- Terpolymers of tetrafluoroethylene, hexafluoropropene and ethyne are known, for example, from GB-A-1 355 595 and US-A-3 817 951.
- Copolymers of tetrafluoroethylene and propene are known from WO-A-96/18665.
- composition according to the invention therefore combines on the one hand with rubber and on the other hand with (a layer of) the adhesion promoter.
- the adhesion promoter in turn combines with layers of other fluoropolymers.
- the most diverse laminates can be produced in this way, the layers made of rubber and fluoropolymers and thus combine the properties of these two material classes.
- Adesion promoters Mixtures of copolymers of the same type or copolymers composed of different monomers can be used as adhesion promoters. Uniform adhesion promoters are advantageously used.
- One aspect of the invention relates to a laminate that contains a layer of an adhesion promoter and a rubber.
- a laminate can be constructed, for example, as follows: a) an upper layer consisting essentially of an adhesion promoter, and b) said layer consisting essentially of a mixture of a rubber and adhesion promoter.
- Layer a) can adjoin a layer made of a fluoropolymer, that is to say that such a laminate constitutes an intermediate product for composite bodies.
- This intermediate product can adjoin layer b) with one or more rubber layers which are or are connected by vulcanization.
- the invention further relates to laminates in which both outer sides consist of a fluoropolymer, so that there is only a chewing action in the interior.
- the amount of adhesion promoter in layer b) can vary within wide limits and is usually in the range from 10 to 70% by weight, preferably 20 to 50% by weight.
- rubber i.e. in addition to natural rubber, the usual synthetic rubbers based on butadiene, butadiene-acrylonitrile, butadiene-styrene, chloroprene, isoprene, isobutene, ethylene-propylene, ethylene-vinyl acetate, acrylate and epichlorohydrin , as well as butyl, chlorobutyl, bromobutyl, polysulfide, urethane, fluorine or silicone rubbers, chlorinated and chlorosulfonated polyethylene and hydrogenated acrylonitrile-butadiene rubber.
- the laminates according to the invention can be produced by mixing a rubber with the adhesion promoter or incorporating one component into the other, for example by kneading, whereupon a flat or spatial structure is produced from this mixture, vulcanizing it, optionally with a layer of rubber is what is applied to at least one layer of adhesion promoter and fixed.
- the coupling agent can be in the form of a powder, in the form of a film, melt or as a liquid preparation, for example as a solution or dispersion, in accordance with customary methods Methods are applied. Such methods include spraying, pouring or knife coating, which are mastered by a person skilled in the art in accordance with the usual specialist knowledge.
- the laminates obtained in this way combine the advantages of the fluoropolymer outer layer, in particular the chemical and thermal insensitivity and the non-stick properties, with the resilience and thus mechanical insensitivity of the rubber sub-layer or intermediate rubber layer.
- Such laminates can be used for many purposes since, for example, more or less rigid layers made of fluoropolymers can now be provided with an elastic rubber back.
- Such laminates can therefore in chemical apparatus construction as well as in
- Automotive industry sealing technology, used in expansion joints, hoses and filler neck.
- a mixture of 80% rubber mixture and 20% terpolymer is produced and vulcanized in several layers.
- the layers show very good adhesion.
- a mixture according to Example 1 is processed into a layer and vulcanized with a layer consisting only of the rubber mixture.
- the layer shows very good adhesion after vulcanization, that is to say the layer containing the terpolymer gives very good adhesion to the layer made of the rubber mixture.
- the laminate obtained in this way can be processed with the layer containing the terpolymer in a separate step with an adhesion promoter layer.
- the terpolymer is only sieved onto a layer of the rubber mixture, then a layer of the rubber mixture is placed over it and the composite is vulcanized, there is no adhesion.
- a laminate is produced, that is to say a composite of which one layer contains the terpolymer.
- the terpolymer is sieved onto this layer in a thin layer and sintered by heating.
- the top layer of the terpolymer adheres excellently to the composite.
- a composite is produced according to Example 5 and a solution of the terpolymer in methyl ethyl ketone is applied to the layer containing the terpolymer and the solvent is evaporated.
- a film of a second terpolymer of the following composition is applied to the lacquer layer thus obtained: 57% tetrafluoroethylene units, 30% hexafluoropropene units and 13% ethylene units and vulcanized. A bond with good adhesion is obtained.
- a mixture of 50% rubber mixture and 50% of the second terpolymer mentioned in Example 6 is prepared, a layer is prepared therefrom, this is combined on one side with a rubber layer and on the other side with the film mentioned in Example 6. Vulcanization gives a bond with good adhesion.
- a layer is produced from 30% rubber mixture and 70% of the second terpolymer mentioned in Example 6 and is connected on one side to a rubber layer and on the other side to the film mentioned in Example 6. A bond with good adhesion is obtained.
