Problems solved by technology

However, HIPS is very flammable, and releases a large amount of black smoke and toxic gases during combustion, which limits its application. In order to broaden its application range, flame retardant modification must be carried out
The most commonly used flame retardants for traditional flame retardant HIPS are brominated compounds. Although such flame retardants have high flame retardant efficiency and reasonable price, they will release toxic gases when burned, polluting the environment, especially polybrominated diphenyl ethers. PBDD (polybrominated benzoxin) and PBDF (polybrominated dibenzofuran) will be released when thermal degradation or burning of these compounds. The European Union's ROHS directive has proposed to ban the use of brominated biphenyls, polybrominated diphenyl ethers, etc. flame retardant

Description

Technical field [0001] The invention relates to a synthetic material, in particular to a halogen-free flame-retardant high-impact polystyrene blend and a preparation method thereof. Background technique [0002] High-impact polystyrene (HIPS) is generally polystyrene modified by grafting styrene and a small amount of butadiene monomer. It has excellent processing properties, mechanical properties, electrical properties, stable dimensions, and good appearance of molded products. The price is low, so it is widely used in household appliances, office equipment, instruments, auto parts, daily appliances and packaging materials. In recent years, international oil prices have been rising steadily, and the prices of downstream products in the petrochemical industry, such as resin raw materials, have generally risen, putting tremendous production pressure on the home appliance, chemical, and construction industries. The products originally produced using acrylonitrile-butadiene-styrene ...
