Abstract

The invention discloses a chlorosulfonated polyethylene microporous foam material and a method for preparing the same. The chlorosulfonated polyethylene microporous foam material in a formula comprises 100 parts of chlorosulfonated polyethylene, 1-6 parts of stabilizers, 0-100 parts of fillers, 0-30 parts of plasticizers, 1-3 parts of anti-aging agents, 0.5-20 parts of vulcanizing agents and 5-12 parts of accelerators. The chlorosulfonated polyethylene microporous foam material can be prepared by the aid of the method according to the formula. The method includes uniformly mixing chlorosulfonated polyethylene rubber, the stabilizers, the fillers, the plasticizers, the anti-aging agents, the vulcanizing agents and the accelerators with one another to obtain mixtures; batching out the mixtures and molding and pre-vulcanizing the mixtures; placing the mixtures in foam devices to obtain the chlorosulfonated polyethylene microporous foam material which is a chlorosulfonated polyethylene rubber foam material. The chlorosulfonated polyethylene microporous foam material and the method have the advantages that the chlorosulfonated polyethylene microporous foam material is light, comprises micropores, is good in mechanical property, is non-toxic and environmentally friendly and can be widely used in diversified fields of heat-resistant and radiation-resistant cable sheaths, rubber floor mats, shoe materials, plastic tracks, automobiles, aerospace and the like.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a chlorosulfonated polyethylene microporous foam material and a preparation method thereof. Background technique [0002] Chlorosulfonated polyethylene is a chlorine-containing special elastomer material with a highly saturated chemical structure obtained by chlorination and chlorosulfonation of polyethylene as the main raw material. It is a special rubber variety with high performance and quality. Its appearance is white or milky white elastic material, thermoplastic. Due to the chlorosulfonyl active group in the molecular structure, it exhibits high activity, especially in chemical medium corrosion resistance, ozone oxidation resistance, oil erosion resistance, flame retardancy, etc., and also has weather resistance, heat resistance, and ion resistance. Radiation, low temperature resistance, abrasion resistance and electrical insulation and excellent mechanical pro...
