A kind of cable material filler and preparation method thereof

Abstract

The invention relates to a cable material filler which is prepared from the following raw materials in parts by weight: 0.5-0.7 part of zinc glycinate, 0.2-0.3 part of folic acid, 0.4-0.5 part of insect wax, 1-2 parts of sodium antimonide, 3-5 parts of magnesium silicate, 1.2-1.5 parts of disodium edetate, 1-1.3 parts of sodium polyacrylate, 1.4-1.6 parts of polyamide modified alkyd resin, 2-4 parts of diisononyl phthalate, 0.2-0.3 part of zinc soap, 2-3 parts of active nano calcium carbonate, 75-80 parts of medical stone powder, a right amount of water, a right amount of 4-6% hydrochloric acid and 10-15 parts of assistant. The filler has the advantages of favorable hydrophobicity, favorable compatibility with the cable material and high breakdown resistance, and can endow the cable with favorable light fastness, heat resistance, aging resistance and electrical insulation properties; and the filler has favorable water resistance, favorable extraction resistance and low toxicity, can be widely used in the cable material, and can lower the cost, thereby obtaining higher economic benefit.

Description

technical field [0001] The invention belongs to the field of cable sheathing materials, in particular to a cable material filler and a preparation method thereof. Background technique [0002] The cable outer sheath is a structural part that protects the insulation layer of the wire and cable from environmental factors. Cable materials include rubber, plastic, nylon and other varieties, all of which have their own excellent characteristics. Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagent resistance, high tensile strength, elongation and reversible crystallinity, bonding Good performance, aging resistance, heat resistance, oil resistance, chemical corrosion resistance, can be used for a long time at 80 ~ 100 ℃, has a certain flame retardancy; but also has disadvantages, such as poor storage stability, and with the cable The scope of ap...
