COMPOSITE MATERIAL FOR INDUSTRIAL RUBBER ARTICLES AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2019 - IPC C08L9/06 C08K7/02 C08J3/20 B29B11/16

Abstract RU 2700065 C2

FIELD: chemistry.

SUBSTANCE: invention relates to rubber industry, in particular, to a composite material based on a rubber mixture reinforced with a cord, and a method for production thereof. Composite material for industrial rubber articles contains, wt. %: rubber mixture based on butadiene-methylstyrene rubber - 50–80 and ground rubber-coated polyamide cord with fibre length of up to 10 mm - 20–50. After crushing the cord on crushing equipment it is mixed with rubber, technical carbon, mineral fillers and plasticisers. Mixture is rolled into sheets, mixed with curing agent ingredients and rolled with forming of calender effect.

EFFECT: invention increases specific volumetric resistance to electric current and sliding friction coefficient of rubber article on steel.
