Abstract

The invention discloses a flame-retardant plastic for a cable. The flame-retardant plastic is prepared from, by weight, 40-60 parts of polypropylene, 30-40 parts of epoxy resin, 15-35 parts of nitrile rubber, 20-30 parts of polycarbonate, 10-30 parts of nano titanium dioxide, 10-20 parts of silicon micro-powder, 5-15 parts of potassium titanate whiskers, 3-8 parts of silicon carbide nanopowder, 5-10 parts of ethyl naphthol, 8-16 parts of chlorinated paraffin, 2-8 parts of montmorillonite, 5-10 parts of calcium stearate, 4-10 parts of zinc borate, 2-6 parts of carbon black, 2-6 parts of filler and 4-6 parts of assistant. The flame-retardant plastic for the cable has a good flame retardant effect and can meet the requirements of fireproof construction materials. In addition, an operation process is simple and easy to achieve and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a flame-retardant plastic for cables and a preparation method thereof. Background technique [0002] Plastic is a polymer material with special properties. It has the characteristics of light weight, good chemical stability, corrosion resistance, good insulation, convenient molding, and low cost. It is widely used in electronics industry, automobile manufacturing, aerospace, industry and other fields. . However, plastics are flammable and burn quickly, producing a large amount of toxic gases. According to statistics, casualties caused by suffocation and smoke poisoning in fires account for 50-80% of the total fire casualties. In recent years, the rapid development of electronics, construction, aviation and automobile industries has put forward higher requirements on the performance of plastics. Among them, flame-retardant plastics are not easy to burn, have low flame propagat...
