Embodiment Construction

[0012] A high weather-resistant cable material for railway passenger cars, made of the following raw materials in parts by weight: EPDM rubber 60, epichlorohydrin rubber 40, polypropylene 25, trifluoropropyl methyl silicone oil 8, dicyclopentadiene petroleum Resin 10, insoluble sulfur 3, N,N'-m-phenylene bismaleimide 2, magnesium methacrylate 2.5, zinc oxide 1.5, low molecular weight polybutadiene 5, titanium dioxide 7, nano xonotlite 12. Cashew nut shell liquid 8, quick press carbon black N55025, o-diallyl bisphenol A6, N,N'-di(β-naphthyl)-p-phenylenediamine 2.5, cadmium diethyldithiocarbamate 2. Zinc hydroxystannate 2, ammonium octamolybdate 16, modified stone powder 18;

[0013] The preparation method of the modified stone powder is as follows: (1) Weigh coke gemstones, volcanic stones, and attapulgite at a weight ratio of 7:5:3, mix them uniformly, calcinate at 780°C for 1.5h, cool naturally to room temperature, pulverize, pass Sieve, stand-by; (2) get the solid content t...

Abstract

The invention discloses a high-weather-resistance cable material for railway passenger trains and a preparation method thereof. The cable material is prepared form the following raw materials in parts by weight: 40-60 parts of ethylene-propylene-diene monomer, 35-45 parts of epichlorohydrin rubber, 20-30 parts of polypropylene, 5-10 parts of silicone OV-210, 10-15 parts of dicyclopentadiene petroleum resin, 2-4 parts of insoluble sulfur, 1.5-2.5 parts of N,N'-m-phenylenedimaleimide, 2-3 parts of magnesium methacrylate, 1-2 parts of zinc oxide, 4-6 parts of low-molecular-weight polybutadiene, 5-10 parts of titanium dioxide, 9-16 parts of nanometer xonotlite, 5-10 parts of cashew shell oil, 20-30 parts of fast extruding furnace black N550, 4-8 parts of diallyl bisphenol A, 2-3 parts of N,N'-di-2-naphthyl-p-phenylenediamine, 2-3 parts of cadmium diethyldithiocarbamate, 1.5-2.5 parts of zinc stannate, 12-18 parts of ammonium octamolybdate and 15-20 parts of modified stone flour. The cable material has excellent weather resistance, thermal aging resistance, chemical corrosion resistance and fatigue resistance, is usable for a long time in environments of sunlight, moisture, ozone, acid rain and the like, and is long in service life and wide in application prospect.

Description

technical field [0001] The invention relates to a high-weather-resistant cable material for railway passenger cars 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 weather resistance of cable materials used in railway passenger vehicles is poor, and aging and cracking are prone to occur after long-term use. performance. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, provide a high weather resistance cable material for railway passenger cars and its preparation metho...
