Embodiment Construction

[0013] A blended polymer of chlorinated polyethylene-chloroprene rubber, wherein the proportion of chlorinated polyethylene is greater than 40% of the weight of the blended polymer.

[0014] The blended polymers of chlorinated polyethylene and neoprene described in the present invention are mixed according to the following parts by weight, and an open rubber mixer or a twin-screw blending extruder is used to obtain chlorinated polyvinyl chloride blended in any proportion. The copolymer of ethylene-chloroprene rubber is blended by rubber-plastic mechanical melt blending method. The ratio of chlorinated polyethylene and neoprene rubber and the obtained performance indicators are shown in Table 1:

Abstract

The present invention relates to one kind of polymer mixture of chlorinated polyethylene and neoprene. The polymer mixture contains chlorinated polyethylene over 40 wt%, and neoprene, as well as vulcanizing agent, stuffing, promoter, antiager, plasticizer, scorch retarder, stabilizer, etc. The polymer mixture has lowered neoprene consumption, low cost, ozone tolerance, high heat resistance, high weather resistance, high corrosion resistance, and other advantages.

Description

technical field [0001] The invention relates to a blend polymer of chlorinated polyethylene-chloroprene rubber. Background technique [0002] Chlorinated polyethylene CPE can be dissolved with most plastics and rubbers, and has heat resistance, oil resistance, ozone resistance, chemical corrosion resistance, weather aging resistance and good electrical properties, etc. Chlorinated polyethylene CPE and neoprene CR It can be widely used in petroleum development, coal mining, aerospace, engineering machinery, automobile manufacturing, shipbuilding, nuclear power plants and other fields of high-performance supporting products. However, compared with chloroprene CR, chlorinated polyethylene CPE , CPE has superior performance and low price. How to reduce the amount of neoprene, ensure the excellent performance of the product, reduce costs as much as possible, and make the product more market-competitive is a problem to be solved in the prior art; at present, CPE and chlorine In t...
