CORD PROCESSED BY POLYUREA-URETHANES Russian patent published in 2014 - IPC F16G1/04 F16G1/28 C09D175/02 C09D175/04 C08G18/10 C08G18/32 C08J5/04 D06M15/564 

FIELD: process engineering.

SUBSTANCE: invention relates to production of drive belts with resilient cord embedded in elastomer substrate including polyurea-urethanes glue composition impregnating said cord and covering fibres. Composition is composed of the product of reaction of polyurethane prepolymer and diamines hardener or water. Said prepolymer represents the product of reaction of diisocyanate with compact symmetric molecules and complex polyetherpolyol, simple polyetherpolyol or polyol polycarbonate. Belt substrate can be made of moulded polyurethane, rubber or thermoplastic elastomer. Said cord can include adhesive coating.

EFFECT: perfected design.
