Abstract

The invention discloses an anti-tear cable material used for a high-speed railway motor train unit and a preparation method of the anti-tear cable material. The anti-tear cable material used for the high-speed railway motor train unit comprises the following raw materials in parts by weight: 67 to 89 parts of polyurethane rubber, 22 to 36 parts of styrene-butadiene rubber, 15 to 25 parts of thermoplastic polyester elastic bodies, 4 to 8 parts of vinyl silicone oil, 17 to 26 parts of fumed silica, 3 to 6 parts of cadmium carbonate, 2 to 3 parts of lauroyl peroxide, 1.5 to 2.5 parts of triallyl isocyanurate, 1 to 2 parts of ammonium benzoate, 3 to 5 parts of poly-alpha-olefin, 5 to 10 parts of tert-butyl phenolic tackifying resin, 2 to 4 parts of triethylhexanoin, 10 to 15 parts of methylpentachlorostearate, 14 to 18 parts of carbon nano tubes, 10 to 15 parts of a diopside powder, 1 to 2 parts of 4,4'-dithiodimorpholine, 0.5 to 1 part of P-tert-butylphenol, and 20 to 25 parts of a composite flame retardant. The cable material provided by the invention combines the advantages of the raw materials such as the polyurethane rubber, the styrene-butadiene rubber, and the thermoplastic polyester elastic bodies, the tearing strength of a conventional cable material is improved, and the cable material is enabled to have excellent tear resistance, has the effect of bearing relatively great mechanical external force, and has the advantages of excellent chemical stability, heat resistance and age resistance, and long service life.

Description

technical field [0001] The invention relates to a cable material, in particular to a tear-resistant cable material for a high-speed railway EMU 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 vehicle 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 poor tear resistance, resulting in short service life and unable to meet market demand. Therefore,...
