Abstract

The invention discloses a high-strength cable material used for a railway vehicle, and a preparation method thereof. The high-strength cable material is prepared from the following raw materials by weight: 85-105 parts of polyphenylene sulfide, 40-60 parts of aromatic polycarbonate, 25-35 parts of ethylene-methyl acrylate-glycidyl methacrylate terpolymer, 4-8 parts of diphenyl-methane-diisocyanate, 12-16 parts of bis(4-carboxyphenyl)phenyl-phosphine oxide, 10-15 parts of zinc aluminate, 20-30 parts of magnesium hydroxide,8-12 parts of basalt short fibers, 2-3 parts of methacryloyloxy propyltrimethoxysilane, 3-5 parts of tri-(stearic mercaptoacetate)antimonium, 2-3 parts of calcium stearate, 1.5-2.5 parts of barium stearate, 4-8 parts of erucyl amide, 3-6 parts of polyethylene wax, 15-20 parts of calcined clay, 10-15 parts of basic magnesium chloride whiskers, 20-30 parts of precipitated white carbon black, 14-18 parts of modified stone powder, 10-15 parts of epoxidized methyl acetorieinoleate and 2-3 parts of an antioxidant 1222. The cable material provided by the invention has the advantages of high mechanical strength, high flame retardance, fire resistance, good thermal stability, excellent electrical insulation property, wide usage temperature range, etc.

Description

technical field [0001] The invention relates to a high-strength cable material for rail vehicles and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] In recent years, with the rapid development of national rail transit, the control of motor train units and high-speed units has become more and more complex, and there are more and more electrical control equipment, the demand for cables will inevitably increase accordingly, and the performance requirements for cable materials will also increase. getting stricter. At present, the mechanical strength of cable materials on the market can no longer meet the performance requirements of rail vehicle cables with faster and faster speeds. Therefore, it is urgent to change the formula of traditional cable materials and develop a high-strength cable material to improve the safety performance of rail vehicle cables. Contents of the invention [0003] The purpose of the present inve...
