Abstract: 1304927 Rubber and polyester fibre laminates UNIROYAL Inc 13 March 1970 [17 March 1969] 12096/70 Heading B5N [Also in Division C3] The adhesion of rubber compositions containing amines or amine-yielding substances, e.g. accelerators, to polyester textiles isimproved by adding a deterioration preventing substance effective to interact with the amine or amine yielding substance to mitigate its effect to the composition before the application and vulcanization of the rubber on the textile. The deterioration preventing substance is selected from benzaldehyde, salicylaldehyde, 3-chloromethyl salicylaldehyde, 3-chloromethyl-5- hydroxybenzaldehyde, furfural, m-hydroxy. benzaldehyde, p-hydroxybenzaldehyde, 2,4- dihydroxybenzaldehyde, 2,4-dimethoxy benzaldehyde, 2,3-dimethoxy benzaldehyde, vanillin, verataldehyde, 5-methoxy salicylaldehyde, cinnamic aldehyde, 2 - ethyl - 4 - hexanal, p - isopropyl benzaldehyde, 2,2 - dimethyl - 3,4- octadienal, terephthaldehyde, dialkyl oxalates, butyl butyrate, butyl lactate, ethyl carbonate, ethyl succinate, dimethyl terephthalate, 2- ethylhexyl acrylate, ethyl p-toluene sulphonate, triacetin, methyl salicylate, butyrolactone, 2,2,4-trimethyl pentenolactone, linear or cyclic lactide polymers, tetramethyl-1,3-butanedione, benzil, benzoin, 1,3 - cyclohexanedione, pquinone, dimedone, 1,3 - dihydroxypropanenone, d,l-camphor, dehydroacetic acid, 2,5- dicarbethoxy-1,4-cyclohexandione, acetoacetic esters, butyl pyruvate, triglycol dichloride, benzyl chloride, p-xylene dichloride, α,α,α-trichlorotoluene, 1,4 - bis - (trichloromethyl) benzene, aniline hydrochloride, dianiline-1,5- naphthalenedisulphonate, zinc - p - toluenesulphonate, zinc benzenesulphonate, sodium 2- formyl benzenesulphonate, tetraethyl orthosilicate, tetra - (2 - ethyl - hexyl) orthosilicate, tetra - (2 - ethyl butyl) orthosilicate, triisodecyl orthoformate, vinyl triethoxy-silane, 2 - nitro - 2 - methyl - 1, 3 - propanediol sulphite, m-phenylene diisocyanate, phenyl-isothiocyanate, vinyl cyclohexene dioxide, styrene oxide; epichlorohydrin-bisphenol A condensate epoxy resins, isotoric anhydride, dodecenyl sucoinic anhydride, octadecenyl succinic anhydride, polyglyoxal, polyvinyl acetate, trialdehyde starch or poly-(methylvinyl ketone). The rubber composition may comprise natural or synthetic rubbers such as polybutadiene; polyisoprene, polychloroprene, copolymers of dienes with styrene, acrylonitrile, vinyl pyridene, ethyl acrylate, isobutylene or copolymers of at least 2 α-olefins such as ethylene, propylene or butene-1 with one or more polyenes, especially the non-conjugated dienes such as dicyelopentadiene, ethylidene norbornene, methylene norbornene, cyclo-octadiene, tetra-hydroindene of 1,4-hexadiene. The composition may also contain vulcanizing agents, activators, tackifiers, lubricants, retarders, antioxidants, antiozonants, peptizers, extenders, fillers and pigments. The polyester textile may be in the form of mono- or multifilaments, plied yarns, cords, staple fibres, woven fabrics or non-woven mats. Adhesives, e.g. rubber latices may be applied to fabric by spraying, dipping, painting or spreading before application of the rubber compositions. The rubber-textile composites are suitable for use in the construction of tyres.
