RUBBER MIXTURE CONTAINING SBR RUBBER GEL

Japanese Patent JP3794810

B2

PROBLEM TO BE SOLVED: To obtain the subject mixture comprising a styrene/butadiene rubber gel and a rubber containing double bonds and capable of producing a vulcanization product advantageous in both a rolling-resistant property and a gripping property in a wet state.
SOLUTION: This rubber mixture comprises (A) 1-100 pts.wt., preferably 5-75 pts.wt., of a styrene/butadiene copolymer rubber gel having a particle diameter of 5-1000nm and a swelling index of 1-15 in toluene, (B) 100 pts.wt. of a carbon-carbon double bond-having rubber preferably comprising natural rubber or a synthetic rubber and having carbon-carbon double bonds corresponding to an iodine value of at least 2, preferably 5-470, and a Mooney viscosity: ML 1+4/100°C (DIN 53 523) of 10-150, and, if necessary, (C) a filler, an auxiliary substance for the rubber, etc. A vulcanization product obtained from the mixture has a high dynamic attenuating property at low temperature and a low dynamic attenuating property at high temperature, and can advantageously used for tire treads, shoe soles, sealing rings, etc.
