Abstract

The invention relates to the technical field of preparation of cable insulation materials, in particular to a preparation method of a high-toughness anti-aging cable insulation material. The preparation method comprises the steps of: firstly adopting pig bones as a raw material, carrying out mildew and fermentation treatment, finally performing blending and impregnation on the moldy product, tea polyphenols and honey so as to obtain impregnated filter residues, mixing the impregnated filter residues, epoxy resin, silicone rubber and the like, conducting vulcanization and smelting, and finallyperforming extrusion and material discharging to obtain the high-toughness anti-aging cable insulation material. The added impregnated filter residues is prepared by modifying the pig bones, and a cross-linking reaction occurs between collagen molecules on the pig bones and the silicone rubber and resin, so that the toughness and elasticity of the finally prepared cable material are improved; since brushite in the pig bones is a high temperature-resistant inorganic substance, the high temperature resistance of the cable insulation material is improved, blending and impregnation are also conducted on the fermented modified pig bones, tea polyphenols and viscous honey, and the tea polyphenols are introduced through cross-linking modification, so that the anti-aging property of the cable insulation material is improved, and a broad application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of preparation of cable insulating materials, in particular to a preparation method of high-toughness and aging-resistant cable insulating materials. 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: Conductive core, made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be made of a single wire or multiple wires twisted; the insulating layer, the insulating material used for the cable should have high insulation resistance, high breakdown electric field Strength, low dielectric loss and low dielectric constant; sealed sheath to protect the i...
