The invention provides a halogen-free low-smoke flame-retardant cable material, comprising: 100 parts by weight of matrix resin linear low density polyethylene, 10-14 parts by weight of melamine cyanurate, 30-34 parts by weight of piperazine pyrophosphate, hydrogen 20-40 parts by weight of aluminum oxide, 15-20 parts by weight of magnesium hydroxide, 10-15 parts by weight of compatibilizer, 0.8-1 part by weight of antioxidant, 1-2 parts by weight of silicone masterbatch; The resin is composed of linear low-density polyethylene and ethylene-vinyl acetate, and the mass ratio of the linear low-density polyethylene and ethylene-vinyl acetate is 1-3:1-2. After mixing and processing with multi-component flame retardants such as melamine cyanurate, piperazine pyrophosphate and aluminum hydroxide, the flame retardant performance of the halogen-free low-smoke cable material has been significantly improved while ensuring the mechanical properties. At the same time, it was observed that the amount of smoke generated by the material also decreased, and it has good flame retardancy. |
