FIELD: chemistry.
SUBSTANCE: rubber mix consists of (mass part): styrol-butadiene rubber containing 22-25 mass % of styrol - 85-95, divinyl rubber containing 87 to 95% of cis-1,4 units - 5-15, vulcanising group (sulfur - 0.5-1.0, 2-mercaptobenzothiazole - 0.5-1.0, N,N'-dithiodimorpholine - 1-2, molten w,w'-hexachloroparaxylene in wax coating - 1-2, stearic acid - 0.9-2.0, zinc oxide - 4-5), N-phenyl-N'-isopropyl-n-phenylenediamine - 1-2, polymerised 2,2,4-trimethyl-1,2-dihydrochinoline - 1-2, carbon black with specific geometrical surface of 33-36 m2/g - 30-50, kaoline - 20-40, chalk - 25-30, coumarone-indene resin - 2-3, zinc diethyldithiocarbamate - 0.9-1.1, oil paraffin wax - 2-3.
EFFECT: higher specific bulk resistance rate without changing achieved thermal fragility range.
