MINERAL FILLER FOR RUBBER BASED ON VINYLSILOXANE RUBBER, BUTADIENE-NITRILE SYNTHETIC RUBBER AND BUTADIENE-ALPHA-METHYLSTYRENE RUBBER

摘要

FIELD: chemistry. ^ SUBSTANCE: sludge formed during lime treatment and coagulation crude water on the water treatment installation of thermal power plants, having chemical composition CaCO3+ MgO + Mg(OH)2 +SiO2 +Fe(OH)3 +Al(OH)3 is used as mineral filler for rubber based on vinylsiloxane, butadiene-nitrile synthetic rubber and butadiene--methylstyrene rubber in amount of up to 50% of the weight of the rubber. ^ EFFECT: invention widens the range of rubber filler materials, lowers the cost of rubber, and solves the problem of recycling thermal power plant wastes. ^ 3 dwg, 1 tbl
