High-performance cable insulating material formula

Abstract

The invention discloses a high-performance cable insulating material formula. A high-performance cable insulating material is prepared from, by weight, 30-36 parts of inorganic filler, 18.3-22.6 parts of carbon black, 39-46 parts of a silane coupling agent, 16-20 parts of antioxidant, 10-30 parts of a cross-linking agent, 2.5-3.5 parts of a vulcanizing agent, 20-22 parts of flame retardant, 12-20 parts of oxide, 6-21 parts of an anti-aging agent, 28-39 parts of oxygen indexes, 6-20 parts of borax, 23-30 parts of boric acid, 18-26 parts of cellulose fibers, 9-30 parts of titanium dioxide, 13-26 parts of chlorinated paraffin, 25-32 parts of a lubricating agent and 33-36 parts of compatilizer. The material is reasonable and scientific in formula, good in irradiation resistance and waterproof performance and excellent in mechanical performance, mechanical performance and physical performance of a produced finished cable are higher than those of common rubber, and flame retardance, abrasion resistance, high using safety and long service life are achieved.

Description

technical field [0001] The invention relates to a formula of high-performance cable insulating material. Background technique [0002] The cable sheath is a layer of rubber wrapped around the cable core to insulate and protect the inner conductor. The quality of the cable sheath depends on the insulation performance and formula, fire resistance and mechanical properties of the sheath. Due to the unreasonable matching of the traditional cable sheath, its insulation performance is average compared with other types of sheaths. After the sheath is put into actual production, it is prone to leakage or even breakdown by high voltage, causing the sheath to be burned or damaged. Cause fire, endanger people's life and property safety. [0003] In view of the defects in the above prior art, it is necessary to further improve it to make it more practical, so as to meet the actual use conditions. Contents of the invention [0004] In order to overcome the defects of the above-mentio...
