Problems solved by technology

[0008] (2) After the flame retardant is added, it cannot affect the mechanical strength of the plastic, especially it cannot reduce the thermal deformation temperature, mechanical temperature and electrical insulation performance of the plastic product;
Mechanisms such as: protective film mechanism, otherwise gas mechanism, cooling mechanism, and termination chain reaction mechanism are given in existing textbooks. These can provide a vague direction for the selection of flame retardants, but they cannot provide real effective information. s help

Description

technical field [0001] The invention relates to a plastic film, in particular to an antibacterial, high-strength talcum powder modified polypropylene plastic. 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 number of casualties in fires. 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 prop...
