RUBBER-CORD COMPOSITE Russian patent published in 2013 - IPC B32B25/10 C08L7/00 C08L9/00 C08L9/06 

FIELD: chemistry.

SUBSTANCE: invention relates to rubber-cord composites and can be used in the tyre and industrial rubber industry. The rubber-cord composite consists of a layer of textile cord which is saturated with a latex-resorcinol-formaldehyde composition based on latex DBA-1 - a copolymer of butadiene, butyl acrylate, methacrylic acid amide or based on latex with vinyl pyridine links, optionally with another latex and optionally containing blocked E-caprolactam polyisocyanate, and a rubber layer. The rubber layer is made from a composition based on unsaturated rubber, with the following ratio of components of the rubber layer, pts.wt: unsaturated rubber - 100; ground technical sulphur - 0.5-0.8; polymeric sulphur - 1.0-1.5; sulphamide TS 0.2-0.4; altax - 0.4-0.7; technical carbon N 550 - 50-55; stearic acid - 1-2; oil-softener - 7-16; resin Pikar - 0.5-2.0; diaphene FP-1-2.5; pine rosin -1-3; zinc oxide - 5-6; modifier RU-D - 1-4 or resin modifier R-17-34 -0.8-1.5; white soot - 5-10; kaolin KR-1- 1-4.

EFFECT: invention increases strength of the textile cord-rubber bond.
