Halogen-free low-smoke flame-retardant TPE cable material

Abstract

A provided halogen-free low-smoke flame-retardant TPE cable material is prepared from the following raw materials in parts by weight: 40-50 parts of polyurethane thermoplastic elastomer, 10-20 parts of POE elastomer, 30-40 parts of polypropylene resin resin, 5-10 parts of PE wax, 15-20 parts of aluminum hypophosphite, 8-10 parts of zinc borate, 10-12 parts of ammonium molybdate, 5-10 parts of ethylene-octene copolymer grafted maleic anhydride copolymer, 0.2-0.3 part of antioxidant 1024, 0.3-0.5 part of antioxidant 1035, 10-12 parts of epoxy butyl oleate, 10-12 parts of dicapryl phthalate, 5-10 parts of dioctyl maleate, 5-6 parts of carbon black N220, 5-10 parts of light calcium carbonate, 1-2 parts of zinc oxide, 5-10 parts of wollastonite powder, 10-12 parts of carbon fiber, 8-10 parts of nanometer boron carbide and 15-18 parts of a modified filling material. Cable conductors prepared from the cable material have the characteristics of being retardant in flame, environment friendly, good in flexibility and the like.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a halogen-free, low-smoke, flame-retardant TPE cable material. Background technique [0002] Wire and cable have the function of power transmission and information transmission, and play an important role in people's life and production. Designing and preparing low-smoke, low-toxic cable materials with excellent flame-retardant and insulating properties has become a hot spot in flame-retardant research today. Although the traditional magnesium hydroxide and aluminum hydroxide flame retardants can endow the material with good flame retardancy, however, since the matrix resin of most cable materials is a non-polar polyolefin polymer, the polar hydrogen The compatibility of magnesium oxide and aluminum hydroxide is poor, which often reduces the mechanical properties and processing properties of materials. It has been studied that the cable material material with good flame retardant...
