ADHESIVE SUBLAYER FOR FIXING RUBBERS TO METAL AT VULCANISATION Russian patent published in 2017 - IPC C09J115/02 C09J161/10 

FIELD: chemistry.

SUBSTANCE: invention relates to an adhesive sublayer based on chlorinated natural rubber used for fixing rubbers based on natural, isoprene, butadiene, butadiene-nitrile, butadiene-styrene, chloroprene, and butyl rubber to metal during vulcanization. The invention can be used in rubber industry in making heat-resistant multilayer rubber-fabric articles, particularly rubber-cord casings and pneumatic tires, as well as flexible high-pressure hoses when operating in aggressive media. The adhesive sublayer includes, ps wt: chlorinated natural rubber - 100, metal oxides - 10.0-20.0, phenol-formaldehyde resin of resole type - 1.0-5.0, phenol-formaldehyde resin of the novolac type - 20.0-50.0, the complex of resorcinol and hexamine - 2.0-15.0, stabiliser - 2.0-10.0, wetting agent - 0.01-0.1, filler - aerosil - 2.0-10.0, xylene and methyl isobutyl ketone - 345.0-400.0.

EFFECT: invention allows to increase the strength of the rubber compound attachment to metal, to reduce toxicity and to improve environmental safety for humans.
