Abstract

The invention relates to a chlorinated polyethylene rubber material, which comprises the following components by weight: 100 parts of rubber-type chlorinated polyethylene, 8-10 parts of magnesium oxide, 3-5 parts of calcium stearate, 0.5-1 parts of 2,2,4-trimethyl-1,2-hydrogenated quinoline polymer, 0.5-1 parts of 4010Na, 40-50 parts of fast extruding furnace black / or white carbon black, 1-2 parts of stearic acid, 10-20 parts of calcium carbonate, 20-25 parts of trioctyltrimellitate, 3-5 parts of adhesive, 2.5-3 parts of 2,4-dimercapto-1,3,4-thiadiazole derivative and 0.2-0.4 parts of N,N-cyclohexylamine-2-benzothiazolesulfenamide. The chlorinated polyethylene rubber has good chemical medicine resistance, aging resistance and good other mechanical properties.

Description

technical field [0001] The invention relates to a chlorinated polyethylene rubber material, in particular to a chlorinated polyethylene material used for preparing rubber hoses, and more specifically to a chlorinated polyethylene material used for automobile cooling water pipes. Background technique [0002] The cooling water pipe is usually composed of inner rubber, outer rubber and a reinforcement layer sandwiched between each rubber (there are also pure rubber hose products). alcohol or rayon fibers. The cooling water pipe is one of the important parts of the car with very strict quality requirements. During the running of the car, the heat loss of the engine is too much, which increases fuel consumption, and the fuel condensed on the cylinder wall flows into the crankcase to dilute the lubricating oil, which intensifies the wear; the engine is overheated, the gas charge is reduced, the combustion is abnormal, and the engine power is reduced and the lubrication is poor. ...
