Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a recycled high-impact polystyrene material and a preparation method thereof. Background technique [0002] Polystyrene material is a polymer synthesized by free radical addition polymerization of styrene monomer. It is a thermoplastic with high transparency, good insulation, easy coloring, and good chemical corrosion resistance. High-impact polystyrene is a thermoplastic material made of elastomer-modified polystyrene. It is a two-phase system composed of a rubber phase and a continuous polystyrene phase. Compared with polystyrene materials, high-impact polystyrene has more High impact resistance, widely used in automobiles, equipment, electric products, furniture, household appliances, telecommunications, electronics, computers, disposables, medicine, packaging and entertainment markets. [0003] With the rapid development of the plastics industry, polystyrene materi...
