METHOD OF VOLCANIZATION OF RUBBER MIXTURE ON THE BASIS OF NATURAL RUBBER Russian patent published in 2018 - IPC C08J3/24 C08L7/00 C08K3/06 C08K3/22 C08K5/09 C08K5/47 

FIELD: technological processes.

SUBSTANCE: invention relates to rubber industry and can be used for production of automobile tires, polymer floor coverings, industrial hoses, conveyors, belts, construction materials. Rubber mixture is vulcanized on basis of natural rubber by means of vulcanizing group: stearic acid, zinc oxide, captax, sulfur, natural amino acid mixture separated from natural latex. Amino acid mixture is isolated from natural latex simultaneously with release of natural rubber by treating natural latex with 1 % aqueous solution of polydiallyldimethylammonium chloride.

EFFECT: method is simplified, vulcanization rate is increased.
