Problems solved by technology

However, since polyolefins are mostly non-polar materials, they have poor compatibility with highly polar inorganic flame retardants, which will seriously affect the processing performance and physical and mechanical properties of cable materials after adding a large amount of inorganic flame retardants.

Abstract

The invention discloses a low-smoke halogen-free flame-retardant cable material and a preparation method thereof. The low-smoke halogen-free flame-retardant cable material is prepared from the following raw materials in parts by weight: 100 parts of matrix resin, 50 to 80 parts of modified aluminum hydroxide, 50 to 80 parts of nano magnesium hydroxide, 10 to 35 parts of ammonium polyphosphate, 1 to 3 parts of molybdenum trioxide, 15 to 20 parts of compatilizer, 0.4 to 1.8 parts of silicone master batch, 1 to 10 parts of nano clay, 5 to 7 parts of nano graphene powder and 0.5 to 2.8 parts of antioxidant, wherein the matrix resin is prepared from low-density polyethylene, a polyolefin elastomer and ethylene-vinyl acetate copolymer resin. According to the low-smoke halogen-free flame-retardant cable material, on the basis of ensuring the insulating property and the mechanical property of the cable material, the flame-retardant effect is excellent, low-smoke and non-toxic effects are realized during combustion, meanwhile, the temperature resistance and the aging resistance of the cable material are improved, and the service life of the cable material is prolonged.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a low-smoke, halogen-free, flame-retardant cable material and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and social economy, people have higher and higher requirements for the safety and environmental protection performance of wire and cable products. Traditional halogen-containing cable materials will release a large amount of toxic hydrogen halide gas when burned, causing damage to personnel safety and construction equipment, and their use is increasingly restricted. Therefore, the development of low-smoke halogen-free flame-retardant cable materials is of great importance. significance. Most low-smoke, halogen-free, flame-retardant cable materials are based on polyolefin, and a large amount of inorganic flame retardants are added to achieve low-smoke, halogen-free, and flame-retardant effects. ...
