Abstract

The invention discloses a chlorinated polyethylene flame-retardant sheath material compound. The flame-retardant sheath material compound comprises compositions with the following weight portions: 100 portions of chlorinated polyethylene, 5 to 8 portions of rare earth complex stabilizer REC-LS, 25 to 30 portions of high-performance complex flame retardant HZR-2, 3 to 5 portions of thiadiazole derivative curing agent, and 1.5 to 2 portions of aldehyde-amine condensate accelerant. A cable obtained by the invention has more comprehensive performance, good mechanical property, ozone-resistant and chemical-resistant performance, flame resistance and oil resistance, high temperature-resistant class, and free color matching.

Description

technical field [0001] The invention relates to the field of wire and cable processing, in particular to a chlorinated polyethylene flame-retardant sheath material composition. Background technique [0002] At present, the main problem of CPE (chlorinated polyethylene) in the field of cables is: CPE (chlorinated polyethylene) series formula problem No matter CPE insulating rubber or sheath rubber, there are immature formulas in the specific applications of domestic manufacturers. There are many problems in the field of production, and even the unqualified problems of product quality such as blistering, hole formation and cracking, so that not only can not use CPE in large quantities, but also increase the production cost due to the increase of waste products. Contents of the invention [0003] The present invention overcomes the above-mentioned shortcomings, and proposes a chlorinated polyethylene flame-retardant sheath material composition, which is suitable for use as a ...
