Halogen-free flame retardant environment-friendly flexible cable sheathing compound for portable power source and preparation method of sheathing compound

Abstract

The invention discloses a halogen-free flame retardant environment-friendly flexible cable sheathing compound for a portable power source. The sheathing 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 urea, 5-6 parts of powdered phenolic resin, 7-8 parts of cotton pulp, 1.5-2 parts of magnesium methacrylate, 3-4 parts of white oil, 9-11 parts of carbon nano tubes, 2-3 parts of zinc oxide and 1-1.2 parts of allyltriethoxysilane. The halogen-free flame retardant environment-friendly flexible cable sheathing compound provided by the invention is not liable to cracking, fold-resistant, halogen-free, flame retardant, harmless to the environment and human bodies, long in service life and suitable for manufacture of cable materials of portable power sources and sheathing compounds of mobile phone data cables.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flexible cable sheathing material for a halogen-free flame-retardant and environment-friendly mobile power supply 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 fully equipped. According to the molecular structure, it can be divided into two types: 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 polyester type polyurethane has poor high temperature hydrolysis resistance and low temperature flexibility. The resistance is not as good as polyether...

Problems solved by technology

[0003] Due to the structure and material of the existing mobile power supply connection cables, it is easy to be damaged during use, not resistant to twists and turns, easy to break, and has poor flame retardancy, which affects the safety of people's study and life. This requires the production of a high-performance cable. Soft cable sheath material for trial mobile power
