Problems solved by technology

The oxygen index of polyether polyurethane material is only 18%, which is a flammable material, and it has thick smoke accompanied by toxic gas and severe molten droplets when burned, and the price of polyurethane is relatively high, which limits its application in the cable industry. Therefore, it is necessary to carry out flame-retardant modification of polyether polyurethane and cross-linking modification on the components

Abstract

The invention discloses a polyurethane/PVC crosslink cable compound for automobile cables. The polyurethane/PVC crosslink cable compound is characterized by being prepared from the following raw materials in parts by weight: 100-102 parts of polyether urethane, 20-21.5 parts of diethyl aluminium hypophosphite, 17-18 parts of melamine cyanurate, 4.3-4.5 parts of aluminium titanate, 50-52 parts of PVC, 1.6-1.8 parts of a cross-linking agent TAIC, 6-7 parts of calcium stearate, 20-22 parts of acetyl tributyl citrate, 4-5 parts of zinc oxide, 3-4 parts of sodium stannate, 3-4.2 parts of liquid paraffin, 2-2.5 parts of urea, 1-1.2 parts of bis(P,P-bis-ethylhexyl diphosphato)ethanediolato titanate, 9-11 parts of 600-mesh calcium carbonate, 5-6 parts of high abrasion furnace black and 2-3 parts of maleic acid di-n-butyl ester. According to the polyurethane/PVC crosslink cable compound for automobile cables and the preparation method of the polyurethane/PVC crosslink cable compound, provided by the invention, by scientific and reasonable compatibility of the components and the controllable process, the product prepared by adopting the preparation method has excellent abrasive resistance, can maintain flexibility at a low temperature, is firm, not liable to cracking, and long in service life.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyurethane / PVC cross-linked cable material that can be used for automobile cables and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane is an elastomer material polymerized by diisocyanate, polyol and chain extender. It has the characteristics of high strength, high elasticity, wear resistance, oil resistance, weather resistance, low temperature resistance, and softness. It is a combination of any rubber and plastic Not all available. According to the molecular structure, it can be divided into two categories: polyether type and polyester type. Due to the complicated use environment of the cable, the required service life is more than 10 years, while the high temperature hydrolysis resistance of polyester polyurethane is poor, and low temperature flexibility The performance is not as good as the polyether type, so polyether polyureth...
