Low-water-adsorbing cable material for high-speed railway motor train unit and preparation method of low-water-adsorbing cable material

Abstract

The invention discloses a low-water-absorbing cable material for a high-speed railway motor train unit and a preparation method of the Low-water-adsorbing cable material. The low-water-absorbing cable material for the high-speed railway motor train unit comprises the following raw materials in parts by weight: 81 to 92 parts of polypropylene, 43 to 55 parts of polybutylene terephthalate, 27 to 39 parts of poly (vinyl chloride co-isobutyl vinyl ether), 3 to 5 parts of vaseline, 22 to 26 parts of crystal silicon micro-powder, 4 to 6 parts of triethoxy-1H,1H,2H,2H-tridecafluoro-n-octylsilane, 1 to 2 parts of 4-hydroxybenzoic acid hydrazide, 3 to 4 parts of zinc pyrrolidone carboxylic acid, 2 to 3 parts of stannous octoate, 4 to 6 parts of glyceryl tristearate, 15 to 20 parts of calcined kaolin, 3 to 4 parts of lead maleate tribasic, 1 to 2 parts of alpha-phenylindole, 21 to 27 parts of a composite fire retardant, and 1.5 to 2.5 parts of an anti-oxidant 1520. The cable material produced by the preparation method provided by the invention is low in water absorption and superior in water resistance, further has excellent performance such as high intensity, excellent thermal stability, shock resistance, aging resistance, corrosion resistance, fatigue resistance, environment friendliness and flame retardance, and the like, and has a very wide application prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to a low water-absorbing cable material for high-speed railway EMUs and a preparation method thereof. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in the high-speed railway motor car industry. In recent years, 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, 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 high water absorption, which leads to short service life and cannot meet market demand. Therefore,...

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 still have the disadvantage of high water absorption, which leads to their short service life and cannot meet market demand.
