Environment-friendly waterproof and double-shielding control cable material and preparation method thereof

Abstract

The invention discloses an environment-friendly waterproof and double-shielding control cable material and a preparation method thereof, materials in terms of parts by weight are: a mixture A: 30-40 parts of methyl vinyl silicone rubber, 10-20 parts of chloroprene rubber, 1-3 parts of semi-reinforcing carbon black, 40-60 parts of modified montmorillonite powder, 1-3 parts of ECHO.A mercapto thiadiazole derivative, 1.5-2.5 parts of triallyl isocyanurate, 1-3 parts of zinc stearate, 3-4 parts of chlorinated paraffin, 10-20 parts of magnesium hydrate and 1-3 parts of octyl ester; a mixture B: 20-30 parts of polypropylene resin, 35-55 parts of chlorinated polyethylene, 25-35 parts of ethylene-vinyl acetate copolymer, 20-30 parts of ethylene vinyl acetate, 0.3-0.5 parts of poly-4-methyl-1-amylene, 2-4 parts of anti-aging agent OD, 2-3 parts of cross-linking agent TAIC (triallyl isocyanurate), 1-3 parts of phenolic resin, 25-35 parts of talcum powder and 1-3 parts of dimethyl dimercapto tin isooctyl. The control cable material has simple preparation method and rational proportion, and drastically improves performance such as tensile strength, elongation at break, tensile strength retention rate and elongation at break retention rate after aging, and impacts brittle temperature performance while obtains excellent performances.

Description

technical field [0001] The invention relates to an environment-friendly waterproof double shielding control cable material and a preparation method thereof, belonging to the technical field of cable materials. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, a large amount of smoke is released. And toxic and corrosive gases are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work, causing serious losses of life and property. At the same time, with the development of communications, automobile industry and computer industry, especially It is suitable for many occasions such as marine wires, automotive wires, high-temperature instrument cables, oil d...
