Abstract

The invention discloses a high-flame-retardance cable coating layer and a preparation method thereof. The high-flame-retardance cable coating layer is prepared from the following raw materials: propylene homopolymer, polyvinylvinyl chloride resin, chlorinated polyethylene, (Z)-but-2-enedioic acid,chloroethene,ethenyl acetatechlorinated vinegar resin, polyurethane, vinisol, vinyl trimethoxy silane,calcium stearate, glass fiber, boron nitride nNano-powder, mineral cotton, antimony trioxide, zinc borate, aluminum triphosphate, magnesium powder, nano-silica, isopropyl phenyl diphenyl phosphate, N,N'-di-furfurylidene-acetone, diphenyl isooctyl phosphate, diphenyl phosphate isopropyl benzene ester, diphenylamine, sulfur, triphenyl phosphate, glycerol triacetate, dimethyl phthalatedimethyl esterphthalate, di-n-butyltin di(monobutyl maleate)mono-n-butyl dimaleate dibutyltin, vulcanizing agent VA-7 and promoting agent BZ. The high-flame-retardance cable coating layer is an intermediate product prepared by the following steps: primary banburying, secondary banburying, mixing and discharging glue are performed to obtain an intermediate product, and vulcanizing the intermediate is vulcanized. The cable coating layer has superior flame resistance and superior abrasion resistance.

Description

【Technical Field】 [0001] The invention belongs to the technical field of cable preparation, and specifically relates to a high flame-retardant cable coating layer and a preparation method thereof. 【Background technique】 [0002] Plastics for wire and cable insulation and sheaths are commonly called cable materials, including rubber, plastic, nylon and other varieties. Cable material manufacturers are based on cable manufacturers, and as long as there is a demand for wires and cables, there is a market for cable materials. In addition to bare wire products such as steel core aluminum stranded wire and magnet wire, almost all wire and cable products require insulation. At present, there are nearly 5,000 wire and cable manufacturers in my country, as well as the transformation of urban and rural power grids, the large-scale development of the western region, and the large-scale upgrade and transformation of communication facilities. There is a huge demand for wire and cable product...
