A wear-resistant and tear-resistant flame-retardant cable

Abstract

The invention discloses a wear-resistant, tear-resistant and flame-retardant cable, comprising: a conductive cable core, an inner protective sheath and an outer protective sheath, the inner protective sheath covers the conductive cable core, and the outer protective sheath covers the inner protective sheath; The raw materials of the protective cover include: thermoplastic polyurethane elastomer, maleic anhydride grafted ethylene-vinyl acetate copolymer, hydrogenated nitrile rubber, dioctyl terephthalate, epoxy soybean oil, trioctyl trimellitate, nano Kaolin, nano calcium carbonate, silane coupling agent modified magnesium hydroxide, melamine cyanurate, dicumyl peroxide, vulcanization accelerator TMTD, magnesium oxide, Ca / Zn composite stabilizer, magnesium stearate, anti-aging Agent CPPD, anti-aging agent IPPD, silicone powder. The invention has good wear resistance, strong tensile and tear resistance, good flame retardancy and good weather resistance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wear-resistant, tear-resistant and flame-retardant cable. Background technique [0002] Thermoplastic polyurethane is a new type of organic polymer synthetic material, which can replace rubber and soft polyvinyl chloride materials. The outstanding features of thermoplastic polyurethane elastomers are excellent wear resistance, tensile strength, tear resistance, impact resistance, good ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and resistance environmental performance. [0003] Melamine cyanurate (MCA) is a nitrogen-containing halogen-free environmentally friendly flame retardant, which has the advantages of non-toxicity, good thermal stability, suitable for material processing, and high flame retardant efficiency. [0004] With the development of my country's modern industry, cables are ...

Problems solved by technology

[0004] With the development of my country's modern industry, cables are used in all aspects of the national economy and people's lives, but cables are often subject to friction and stretching during use, which requires improving the wear resistance, stretch resistance and resistance of cable materials. Tear performance, and the addition of flame retardants will reduce the mechanical properties of the cable material, reducing its toughness and impact resistance, making it easy to tear
