FIELD: chemistry.
SUBSTANCE: composite material for outer lining of rubber-fabric conveyor belts based on stereoregular cis-1,4-polyisoprene with content of cis-1,4 units of at least 96% - SKI-3 contains ultrahigh molecular weight polyethylene modified with carboxyl with subsequent mechanical activation in amount of 5 pts.wt per 100 pts.wt SKI-3.
EFFECT: invention increases wear resistance, improves frost resistance of the composite material while preserving physical and mechanical properties, lowers the cost of the composite material.
