Problems solved by technology

At present, due to cost factors, some ethylene-propylene rubber is replaced by CPE in the industry, which leads to unstable insulation resistance of the wire core, especially when the rubber sheathed wire is soaked in water for a long time, the insulation resistance attenuates greatly.

Abstract

The invention discloses a special stabilizer for a chlorinated polyethylene (CPE) rubber cable material and a processing technology, and the stabilizer is used for preparing the chlorinated polyethylene (CPE) rubber cable material and specifically comprises the following components in parts by mass: 15-25 parts of active magnesium oxide, 30-45 parts of lanthanum stearate, 20-25 parts of barium stearate and 3-5 parts of an antioxidant. The invention provides a stabilizer special for a chlorinated polyethylene (CPE) rubber cable material. The stabilizer is a rubber cable material stabilizer special for a CPE base material and capable of meeting the aging performance and keeping the insulating property not reduced.

Description

Technical field [0001] The present invention relates to the technical field of chemical new materials, and more particularly to the special stabilizer and processing processes of the chlorinated polyethylene (CPE) rubber cable. Background technique [0002] CPE is a high molecule random chloride obtained by substituting the chlorine atom by a chlorine atom, and the material is degraded during processing or use, and free radical resistance agent is added to the material. That is, the free radical absorbers continuously absorb the highly active free radicals produced by the degradation process, thereby avoiding the failure of the radical to the high molecular main chain, and thus the present invention is in a rubber cable material of CPE as a substrate, material degradation HCL acid gases were released, while HCl was an acidic substance accelerated material decomposition aging. Therefore, on the one hand, it is necessary to suppress the decomposition of CPE under high heat or irrad...
