Abstract

The invention belongs to the technical field of high polymer materials, and particularly discloses a thermoplastic non-halogen low-smoke flame-resistant material with a high oxygen index and a strong self-extinguishing property for an electric wire and cable and a preparation method of the material. The flame-resistant material is prepared from, by weight, 100 parts of base resin, 100-140 parts of silicon-alkane activation aluminum hydroxide, 2-10 parts of composite lubricant, 0.2-2 parts of composite antioxidant and 0-2 parts of color masterbatch; the base resin is composed of, by weight, 25-70 parts of polyethylene vinyl acetate, 10-40 parts of linear low-density polyethylene, 5-40 parts of ethylene-octene copolymer and 8-30 parts of maleic anhydride grafted copolymer. The flame-resistant material has the high oxygen index and the strong self-extinguishing property, self-extinguishing can be achieved under the situation of a fire disaster or other extreme cases, and the use safety of the flame-resistant material is greatly improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high oxygen index, strong self-extinguishing thermoplastic halogen-free low-smoke flame-retardant material for electric wires and cables and a preparation method thereof. Background technique [0002] At present, polyvinyl chloride resin is widely used as a material for wires and cables. This material contains halogens, which will release toxic and harmful gases and generate a lot of black smoke during combustion, which not only pollutes the environment, but also easily causes suffocation and death in the event of a fire; Halogen-free low-smoke flame-retardant materials have great advantages in this regard, but there are also big problems in the process of use: [0003] Adding a large amount of halogen-free low-smoke flame-retardant materials as inorganic materials will easily cause a large drop in the mechanical and physical properties of the base material, such as a...
