RUBBER MIXTURE FOR THE SEALING LAYER Russian patent published in 2007 - IPC C08L9/00 C08L23/28 C08L23/22 C08K13/02 C08K3/04 C08K3/06 C08K3/22 C08K5/09 

FIELD: rubber industry; automotive industry; production of the sealing layer at manufacture of the tubeless tires and the pneumatic constructions.

SUBSTANCE: the invention is pertaining to rubber industry and the automotive industry and is dealt with production of the sealing layer at manufacture of the tubeless tires and the pneumatic constructions. The rubber mixture contains the isoprene rubber, the filled chlorbutyl rubber produced by interaction at comixing of the butyl rubber and the hlorinated hydrocarbon of the common formula_{СnН(2n+2)-х С1х, where n = 10-30, х = 7-24, at the temperature of 80-150°С at the presence of the colloid silicon dioxide introduced into the mixture in the process of their comixing, brimstone, the sulfonamide accelerant, the stearic acid, zinc oxide, the high-pressure polyethylene, the engineering carbon, the alkylphenolamide resin. The technical result of the invention consists in the increased protection of the rubber mixture from the possible premature vulcanization in the processes of its preparation and reprocessing.}

EFFECT: the invention ensures the increased protection of the rubber mixture from the possible premature vulcanization in the processes of its preparation and reprocessing.
