Abstract

The invention belongs to the technical field of a cable, and particularly relates to a flame-retardant insulation cable material and a preparation method thereof. The cable material is prepared from the following raw materials in parts by weight: 70 to 90 parts of high density polyethylene, 10 to 16 parts of ethylene-vinyl acetate copolymer, 10 to 20 parts of plasticizer, 3 to 8 parts of flame retardant agent, 0.1 to 0.5 parts of antioxidant, 1 to 5 parts of coupling agent and 6 to 13 parts of aluminum oxide fibers. The flame-retardant insulation cable material has excellent mechanical performance and electric performance, contains no halogen element, and is low in smoke, non-toxic and harmless when in burning and can be widely applied to an insulation and jacket material of a high voltage cable.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a flame-retardant insulating cable material and a preparation method thereof. Background technique [0002] In recent years, with the frequent occurrence of high-voltage power cable fire accidents, the flame-retardant problem of wires and cables has gradually attracted attention. Therefore, in recent years, flame-retardant cable materials have become more and more widely used. It is based on polyethylene resin and added various The multi-component mixed material of the compounding agent is widely used in the insulation and sheath material of wire and cable because of its superior mechanical properties, good weather resistance, excellent electrical insulation performance, easy processing and low cost. [0003] Chinese patent CN103059471B discloses an environmentally friendly, non-toxic, high-insulation and low-temperature-resistant polyvinyl chloride cable material, whi...
