RUBBER ADHESION INTENSIFIERS Russian patent published in 2003 - IPC

FIELD: rubber-processing industry; rubber production. SUBSTANCE: the invention relates to the field of organo-metallic compounds, their compositions and application. The vulcanized rubber mixture contains natural rubber, one or several traditional components of a rubber mixture and, at least one organo-metallic compound as an intensifier of adhesion of general formula where X represents aluminum, titanium, zirconium or silicon, alkyl- or aryl-silicon, or dialkyl-, diaryl- or alkylarylsilicon; M - cobalt or nickel; A - aliphatic carboxylic acid radical with 7-15 atoms of carbon; B - aromatic carboxylic acid radical with 8-15 atoms of carbon or aliphatic or aromatic aryloxicarboxylic acids with 8-15 atoms of carbon; p and q irrespectively are equal to 0.5 up to 1.5; m+n=x, where x represents valency of X, m/n is equal to 0,67-9,0 and n is equal to 0.2-(x-1). The rubber consists of a rubber mixture containing, at least, one intensifier of adhesion and one or several additives. EFFECT: intensifiers allow to increase the rubber adhesion to a steel-wire cord with a brass cover and its preservation at ageing under conditions of vapor or saline medium. 10 cl, 1 tbl, 4 ex
