Problems solved by technology

[0003] EPDM rubber is widely used in cables, sealing strips and cooling water pipes due to its excellent heat resistance, weather resistance and water resistance. According to incomplete statistics, the consumption of EPDM rubber in my country has exceeded 200,000 tons in recent years. And it is increasing year by year, but only Jilin Petrochemical Company has a small amount of production in China, and the gap is extremely huge

Abstract

The invention relates to a rubber composition using both EPDM and reclaimed rubber. The rubber composition comprises 80 to 60 parts of EPDM, 20 to 40 parts of ethylene propylene reclaimed rubber, 3 to 5 parts of zinc oxide, 2 to 6 parts of polyethylene glycol, 1 to 2.5 parts of stearic acid, 2 to 5 parts of coumarone, 1 to 2 parts of an antioxidant RD, 60 to 100 parts of carbon black N550, 50 to 70 parts of carbon black N774, 50 to 70 parts of naphthenic oil, 1.5 to 2 parts of a promoter DM, 1.2 to 1.5 parts of a promoter BZ, 0.5 to 0.8 part of a promoter TT, 0.8 to 1.5 parts of a promoter CZ and 1 to 1.5 parts of a vulcanizing agent. The rubber composition using both EPDM and EP reclaimed rubber is used to replace EPDM rubber in a rubber product, can meet requirements of a material for heat resistance, weatherability and ozone resistance, substantially alleviates the problem of scarcity of EPDM rubber in China, turns the waste into the valuable and realizes reasonable utilization of resources.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber composition using EPDM and EPDM reclaimed rubber in combination. Background technique [0002] Waste rubber mainly comes from waste tires, waste rubber hoses, waste rubber shoes, waste tapes and rubber products, and belongs to the category of industrial solid waste. Its recycling and utilization have attracted more and more attention from all over the world. my country is a country that consumes a lot of rubber, and at the same time it is a country that is very scarce in rubber resources. Reclaimed rubber is a supplementary resource of rubber and one of the indispensable main raw materials for my country's rubber industry. [0003] EPDM rubber is widely used in cables, sealing strips and cooling water pipes due to its excellent heat resistance, weather resistance and water resistance. According to incomplete statistics, the consumption of EPDM rubber in my country has exc...
