Background
The plastic is used as an indispensable synthetic material in the production and life of people, the yield is increased day by day, and the plastic brings convenience to the life of people. Polystyrene plastic refers to a plastic containing styrene in a macromolecular chain, and is one of the most commonly used plastics at present. The polystyrene has the structural characteristics that the main chain of the macromolecule is a saturated hydrocarbon polymer, and the lateral group is a benzene ring with large volume, so that the polystyrene has good electrical property, chemical property, rigidity, dimensional stability and higher hardness, and the strength and the wear resistance of the polystyrene can be improved by adding fibrous or other shaped materials (such as glass fiber, polyester fiber, graphite, silicate and the like) so that the polystyrene is more durable. However, the rigid and hard properties of polystyrene lead to brittle fracture under external stress, which in turn affects the service life.
The polystyrene has higher surface glossiness, and can reflect light, so that glare is generated, the glare can influence the aesthetic degree and the visual experience of plastic products, and meanwhile, in recent years, low-reflection matte and extinction products are increasingly favored by consumers; at the same time, in certain special cases, certain extinction requirements are also imposed on the surface gloss of the product for aesthetic and technical requirements.
