Problems solved by technology

[0003] However, because the TV casing made of high-impact polystyrene (HIPS) is easy to burn under an open flame, a large amount of smoke and toxic gases are generated, and there are great safety hazards. People continue to study the ability to endow high-impact polystyrene ( HIPS) Flame-retardant HIPS plastic modified materials with flame-retardant and self-extinguishing properties. In the past, flame-retardant HIPS plastic modified materials added halogen bromine and antimony inorganic compounds to high-impact polystyrene (HIPS) as flame retardants. , so that the obtained modified material has the performance of flame retardancy
[0004] In order to achieve good flame retardancy, the addition of halogen bromine and antimony is more, which not only leads to high production costs, but also has a serious impact on the physical and mechanical properties of the modified material, resulting in the tensile strength, Bending strength, impact strength, heat distortion temperature and other properties have dropped significantly, resulting in poor impact resistance and short service life of TV casings made of flame-retardant HIPS plastic modified materials. What is more serious is flame-retardant HIPS plastic modified materials. The halogen contained in the material will cause serious harm to the ozone layer of the atmosphere, especially with the improvement of environmental protection standards in various countries, it is required to reduce or eliminate the use of halogen-containing flame retardants, and halogen-containing materials will gradually be eliminated because they do not meet environmental protection requirements
