Formula of rubber hose of peroxide vulcanization radiator

Abstract

The invention relates to a formula of a rubber hose of a peroxide vulcanization radiator, comprising the following ingredients by weight percent: ternary ethylene propylene rubber 100, zinc oxide 5-15, polyethylene glycol 2-4, stearic acid 0.5-1.5, age resister (445) 0.5-2, age resister MMBZ 0.5-2, fast extruding furnace black (N550) 50-90, non-polluted intermediate-particle thermal black (N990) 20-50, talcum powder treated with vinylsilane coupling agent 20-40, liquid polybutadiene 20-40, crosslinking agent BIBP 2-4 and crosslinking aid TAIC 0.5-1.3.Compared with the rubber hose of a sulphur vulcanization radiator, the rubber hose of the peroxide vulcanization radiator has more excellent heat-resistant and ageing-resistant properties, very good cooling liquid resistant property, electrical insulation property and press deformation property, better meeting the demand of water pipes of traditional radiators for automobiles.

Description

technical field The invention relates to a formula of rubber, in particular to a formula of peroxide vulcanized radiator rubber hose. Background technique Automobile rubber hose refers to the rubber hose products used in the three parts of the chassis, engine and body, which are divided into seven systems: oil transportation, gas transportation, drive, control, brake, radiator and heating and cooling. The role of power transmission. 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, one of the important parts of the automobile, has higher and higher requirements for it; the sulfur vulcanization system used in the EPDM radiator hose used in the past can no longer meet the requirements. The requirements for low pressure change, high temperature resistance, coolant resistance and electrical resistance of automobile radiator hoses, so perox...
