Problems solved by technology

[0002] Wires and cables are one of the main carriers of power transmission or information transmission, and are widely used in all walks of life. However, wires and cables are used in different environments, and the requirements for sheaths are not exactly the same. Indoors and crowded places Areas usually require flame retardant materials. However, the flame retardant materials for sheaths in the prior art cannot be applied to other occasions, such as torsion resistance, elongation at break, environmental cracking resistance, acid and alkali resistance, and high and low temperature resistance. can not achieve the desired effect

Abstract

The invention belongs to the technical field of wires and particularly relates to a composite flame-retardant material for wire and cable sheaths. The composite flame-retardant material for wire and cable sheaths is characterized by being prepared from, by weight, 65 parts to 75 parts of polyethylene resin, 22 parts to 28 parts of ethylene-vinyl acetate copolymer, 5 parts to 10 parts of epoxy resin, 2 parts to 4 parts of polyethylene wax, 1 part to 3 parts of ammonium polyacrylate, 2 parts to 4 parts of nano-silicon nitride or nano-silicon carbide or nano-zirconium oxide or nano-aluminum oxide, 30 parts to 40 parts of dioctyl oxalate, 10 parts to 20 parts of polyester type plasticizer with the commercially available model number of PN-850, 3 parts to 5 parts of trimellitic anhydride, 30 parts to 40 parts of magnesium hydroxide or aluminum hydroxide, 6 parts to 10 parts of carbon black and 1 part to 2 parts of antioxidant with the commercially available model number of T501. The composite flame-retardant material for wire and cable sheaths has the main advantages of being better in torsional property, processability and environmental suitability, lower in density, and better in tensile strength, elongation at break and other performance.
