Abstract

A disclosed polyethylene cable insulation material is characterized by being prepared from the following raw materials in parts by weight: 55-60 parts of high-density polyethylene, 13-16 parts of linear low-density polyethylene, 5-7 parts of PE wax, 16-19 parts of diatomite, 23-26 parts of high-wear-resistance carbon black N330, 1-2 parts of promoter TMTM, 1-2 parts of antiaging agent ODA, 14-16 parts of glyceryl trioleate, 2-3 parts of zinc stearate, 2-3 parts of tricresyl phosphate, 1-2 parts of silane coupling agent KH550, 10-12 parts of epoxidized linseed oil and 6-8 parts of an auxiliary agent. By utilizing high-density resin as a base material, the cable insulation material is smooth in surface and relatively good in fluidity, the production technology is simple, easy and practicable, the production efficiency is high, the cable insulation material is good in effect and capable of replacing imported products, and the cable production cost is reduced also.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polyethylene cable insulating material and a preparation method thereof. Background technique [0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can withstand most acids and alkalis. Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation properties. High-density polyethylene, commonly known as low-pressure polyethylene, compared with LDPE and LLDPE, has higher temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, electrical insulation, impact resistance and cold resistance are very good. Well, it is mainly ...
