Environment-friendly tensile high-temperature-resistant control cable material and preparation method thereof

Abstract

The invention discloses an environment-friendly tensile high-temperature-resistant control cable material and a preparation method thereof. The cable material is composed of a mixture A and a mixture B, wherein the mixture A comprises, by weight, 30-40 parts of nitrile rubber, 20-30 parts of silicon rubber, 10-20 parts of polyacrylate, 10-20 parts of poly(styrene-butadiene-styrene), 1-3 parts of semi-reinforcing carbon black, 40-60 parts of modified nano-powder, 1-3 parts of insoluble sulfur, 1.5-2.5 parts of methyltrimethoxysilane, 1-3 parts of zinc stearate, 3-4 parts of antioxidant 1035, 1-3 parts of bi-texanol, 10-20 parts of magnesium hydroxide and 1-3 parts of dioctyl phthalate; the mixture B comprises, by weight, 30-50 parts of nitrile rubber, 20-40 parts of silicon rubber, 20-30 parts of polyacrylate, 0.3-0.5 part of poly(4-methyl-1-pentene) , 2-4 parts of antiager RD, 5-10 parts of polycaprolactone, 2-3 part of crosslinking agents TAIC, 1-3 part of chlorinated paraffin, 5-8 parts of ammonium dihydrogen phosphate and 1-3 parts of isooctyl thioglycolate dimethyl tin. The preparation method is simple, the composite formula is reasonable, the performance of the cable material is improved greatly, thermal resistance, aging resistance and wear resistance of the cable material are good, expansion deformation under high temperature is small, secondary vulcanization is facilitated, and the cable material is low-smoke, flame-retardant, environment-friendly and safe.

Description

technical field [0001] The invention relates to an environment-friendly tensile and high temperature resistant 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 ca...

[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 drilling platform cables, etc. Of course, environmentally friendly tensile and high-temperature resistant control cable materials are also essential
