VULCANIZED RUBBER MIXTURE MADE ON THE BASIS OF THE HEIGHTENED WEAR RESISTANT ACRYLATE RUBBER Russian patent published in 2007 - IPC C08L33/08 C08L9/02 C08K13/02 C08K3/06 C08K3/20 C08K5/09 C08K5/17 

FIELD: rubber industry; chemical industry; production of the vulcanized rubber mixture made on the basis of an acrylate rubber and partially on the hydrogenated butadiene-nitril caoutchoucks.

SUBSTANCE: the invention is pertaining to production of the vulcanized rubber mixture made on the basis of the acrylate rubber and partially on the basis of the hydrogenated butadiene-nitril caoutchoucks, which is used for manufacture of the hardware products operable at the temperatures up to 150°С and having the heightened wear resistance and which may be used in production of the industrial rubber products - the rings, the sleeves gaskets, the drive belts operating in the friction pairs at the heightened temperatures. The vulcanized rubber mixture made on the basis of the acrylate rubber of the heightened wear resistance includes the mineral filler, the engineering carbon, the antioxidant, the plasticizer, the partially hydrogenated butadiene-nitril caoutchouck, the quaternary ammonium base, the metallic stearate, the brimstone, the vulcanization accelerators, zinc oxide, the anti-adhesive agent, the anti-scorching agent. The rubber mixture made on the basis of the acrylate rubber of the heightened wear resistance allows to increase the level of the values of the indexes: the wear resistance, the tensile strength, the frost hardiness, the resistance to the action of the aggressive mediums of the aromatic series.

EFFECT: the invention ensures the increased level of the values of the indexes of the rubber mixture made on the basis of the acrylate rubber of the heightened wear resistance: the wear resistance, the tensile strength, the frost hardiness, the resistance to the action of the aggressive mediums of the aromatic series.
