Problems solved by technology

With the development of the automobile industry, the radiator hose, which is one of the important parts of the automobile, is becoming more and more demanding and demanding. The sulfur vulcanization system used in the EPDM rubber radiator hose used in the past can no longer be used. To meet the requirements of low compression deformation, high temperature resistance and coolant resistance of automobile radiator hoses, so peroxide vulcanized radiator hoses came into being

Abstract

The invention relates to a formula of a peroxide vulcanized ethylene propylene diene monomer (EPDM) water pipe. The formula comprises the following ingredients in part by weight: 100 parts of EPDM, 4.5 to 10.5 parts of zinc oxide, 1 to 6.5 parts of anti-aging agent RD, 0.8 to 3.6 parts of anti-aging agent MB, 0.2 to 3.3 parts of anti-aging agent NBC, 0.5 to 8 parts of crosslinking agent TAIC, 1.8 to 5.2 parts of crosslinking agent DCP, 15 to 40 parts of calcined clay, 80 to 150 parts of fast-extruded carbon black N550 and 51 to 76 parts of paraffin oil. The formula also comprises 0.5 to 6.5 parts of stearic acid. Due to the adoption of the formula, the high temperature resistance, the ozone resistance, the cooling liquid resistance and the oil resistance of the EPDM water pipe can be greatly improved, the service life of the EDPM water pipe is greatly prolonged, the requirement of an automobile factory can be completely met, and the national standard requirement can be reached.

Description

technical field [0001] The invention relates to a rubber water pipe. In particular, it relates to a peroxide vulcanized EPDM water pipe formulation for automobiles. Background technique [0002] Automobile rubber hose refers to the rubber hose products used in the three major parts of the chassis, engine and body, which are divided into seven systems: oil delivery, gas delivery, drive, control, brake, radiator, and heating and cooling. It is mainly used for oil delivery, water delivery and power transmission. effect. Among them, radiator hose is one of the main products. Automobile radiator hose is one of the main uses of EPDM rubber. With the development of the automobile industry, the radiator hose, which is one of the important parts of the automobile, is becoming more and more demanding and demanding. The sulfur vulcanization system used in the EPDM rubber radiator hose used in the past can no longer be used. To meet the requirements of low compression deformation, h...
