Irradiation crosslinking chlorinated polyethylene rubber composition and preparation method thereof

The invention relates to an irradiation crosslinking chlorinated polyethylene rubber composition and a preparation method thereof, and belongs to the technical field of chemical industry. The composition comprises the following raw materials in parts by mass: 100 parts of chlorinated polyethylene rubber, 10-20 parts of a heat stabilizer, 0.5-2.0 parts of an anti-aging agent, 0.5-3.0 parts of a functional additive, 5-25 parts of a polyester plasticizer, 5-15 parts of sodium aluminum silicate, 0.5-2.0 parts of a wear-resistant additive, 5-10 parts of a cold-resistant plasticizer, 25-100 parts ofcarbon black, 5-30 parts of precipitated barium sulfate and 1.5-3.0 parts of a radiation sensitizer. The rubber composition has the characteristics of high water resistance, high wear resistance, weather resistance and corrosion resistance, can replace expensive ethylene propylene diene monomer rubber, TPE (thermoplastic elastomer) or TPU (thermoplastic polyurethane elastomer) and other materials, and is widely applied t
