Problems solved by technology

Among them, chloroprene rubber has good flame retardancy, but the highest temperature resistance is only 90°C, the production extrusion speed is slow, and scorching often occurs, and the price is high; chlorosulfonated polyethylene has flame retardancy and high temperature resistance. Features, the maximum operating temperature can reach 105 ° C, but its price is very high, and the extrusion speed is slow
Because the main chain of chlorinated polyethylene rubber contains chlorine, it has good flame retardancy and oil resistance, as well as high temperature and low temperature resistance. Fast, high production efficiency, but used alone, poor oil resistance

Abstract

The invention relates to an anti-oil and fire-retardant chlorinated polyethylene sheath material with good weather resistance and a preparation method thereof. The sheath material uses chlorinated polyethylene rubber as main raw material and adds chlorosulfonated polyethylene rubber, triallyl isocyanurate, 1,3-bis (tert-butyl peroxide isopropyl) benzene, trioctyl trimellitate, carbon black, antioxidant 1010, ultra-fine talc powder, antimony trioxide, and high-activity magnesium oxide R-150 according to ratios; the preparation method is as follows: at first, mixing part of the auxiliary agents, then mediating, internal mixing, open mixing, granulating and extruding are carried out on the mixture to form cables, thus the cables are obtained. In the formula, high temperature resistant plasticizer is utilized, various auxiliary agents with appropriate proportions are added into the formula, so that chlorinated polyethylene rubber cable material can reach a high temperature of 105 DEG C, and can be used at the lowest temperature of minus 50 DEG C. The sheath material has the advantages of good anti-aging property, excellent electrical insulation and mechanical property, environmental protection and high flame resistance, thereby being suitable for cold and oil-contaminated severe environment and transmission and distribution circuits of which the current-carrying capacities are large and the rated voltages are at or below 450 / 750V. Meanwhile, compared with traditional chloroprene rubber cable material, the sheath material has the characteristics of low cost, fast extruding speed and high output benefit.

Description

technical field [0001] The invention relates to an oil-proof and flame-retardant chlorinated polyethylene sheath material with good weather resistance and a preparation method thereof. Background technique [0002] At present, the rubbers used in cable materials with the characteristics of high temperature resistance, cold resistance, oil resistance and high flame resistance include neoprene, chlorosulfur polyethylene rubber, and chlorinated polyethylene rubber, which has developed rapidly in recent years. Among them, chloroprene rubber has good flame retardancy, but the highest temperature resistance is only 90°C, the production extrusion speed is slow, and scorching often occurs, and the price is high; chlorosulfonated polyethylene has flame retardancy and high temperature resistance. Features, the highest temperature can reach 105 ℃, but its price is very high, and the extrusion speed is slow. Because the main chain of chlorinated polyethylene rubber contains chlorine, i...
