Mildewproof polyphenylene ether cable material for high-speed railway motor train unit and preparation method of mildewproof polyphenylene ether cable material

Abstract

The invention discloses a mildewproof polyphenylene ether cable material for a high-speed railway motor train unit and a preparation method of the mildewproof polyphenylene ether cable material. The mildewproof polyphenylene ether cable material comprises the following raw materials in parts by weight: 38 to 52 parts of polyphenylene ether, 26 to 44 parts of perchloro-ethylene resin, 9 to 16 parts of pentaerythritol stearate, 7 to 11 parts of calcium fluosilicate, 15 to 20 parts of mica powder, 12 to 18 parts of di-2-ethylhexyl maleate, 3 to 6 parts of montan wax acid, 2 to 4 parts of 12-methyl hydroxy stearate, 1 to 2 parts of 1-dodecanethiol di-n-butyltin, 15 to 20 parts of radiobarite powder, 2 to 3 parts of N,N`-diphenyl thiourea, 3 to 4 parts of folphan(makhteshim), 2 to 3 parts of cuprous sulfocyanate and 10 to 15 parts of a composite flame retardant. The cable material produced through the method provided by the invention is excellent in fungus resistance and water resistance, can be used for a long term in moist environment, can prevent mildew breeding, and can effectively reduce moisture invasion, moreover, the mildewproof polyphenylene ether cable material is excellent in mechanical strength, electrical insulating property, wearing resistance, heat resistance, corrosion resistance and flame retardance, and compared with the service life of a common cable, the service life of a cable made of the cable material provided by the invention can be prolonged for 2 to 3 times.

Description

Technical field [0001] The invention relates to a cable material, in particular to a mold-proof polyphenylene ether cable material for high-speed railway EMUs and a preparation method thereof. Background technique [0002] With the rapid economic development, wires and cables have been widely used in the high-speed railway train industry. In recent years, the electrical fire accidents of high-speed railway trains have occurred frequently, and 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 and toxic and corrosive gases are released, which seriously hinders people's safe evacuation and fire fighting work, causing serious loss of life and property. At the same time, the cable materials for high-speed railway EMUs currently on the market generally have the disadvantage of poor mildew resistance, which leads to their short service life and cannot meet market demand. ...

AI Technical Summary

Problems solved by technology

When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which seriously hinders people's safe evacuation and fire fighting work, causing serious loss of life and property.

At the same time, the cable materials for high-speed railway EMUs currently on the market generally have the disadvantage of poor mildew resistance, which leads to a short service life and cannot meet market demand.
