Problems solved by technology

[0003] At present, the insulation layer of the cable is mostly made of polymer materials. In the initial stage of cable use, the insulation layer of the cable has relatively excellent mechanical properties and insulation properties, but after a period of use, the insulation layer will With the use of time limit aging, which greatly degrades the performance of the cable

Abstract

The invention discloses a montmorillonoid modified anti-aging cable insulating material and a manufacturing method thereof. The manufacturing method includes subjecting montmorillonoid, tetrabutylammonium chloride and hydrochloric acid to activating treatment on a condition of decompression, and then filtering to obtain a filter cake to obtain an activated composition; subjecting epoxy resin, neoprene, ethylene-vinyl alcohol copolymer, n-butyl alcohol, hydroxyethyl acrylate, tungsten oxide, tris(dimethylamino)silane, mica powder, diborane, quinoline, dicumyl peroxide, ozocerite, sodium hexametaphosphate and the activating composition to mixing, melting and cooling shaping to obtain the anti-aging cable insulating material. The anti-aging cable insulating material manufactured by the method has excellent insulativity, mechanical property and anti-aging property.

Description

technical field [0001] The invention relates to a cable insulating material, in particular to a montmorillonite-modified anti-aging cable insulating material and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable is mainly composed of the following 4 parts: ① Conductive wire core, made of high conductivity material (copper or aluminum). ②Insulation layer, the insulation material used for cables should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant. Commonly used insulating materials in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber, etc. ③Seal the sheath to protect the insulated wire core ...
