Abstract

The invention discloses a preparation method of a modified high impact polystyrene (HIPS) composite material. The method includes the following steps: preparing a HIPS prefabricated material, and performing injection molding; putting the material into a polyvinyl alcohol solution, and adding ammonium ferrous sulfate; after soaking is performed, taking out the material, and performing irradiation by using an ultraviolet lamp; performing washing by using acetone, immersing the material into distilled water, and adding [3-(2,3-epoxypropoxy)propyl]trimethoxysilane dropwise; and adding ethylene diamine dropwise, performing heating, performing a reaction, and performing washing to obtain the modified HIPS composite material. According to the method provided by the invention, the surface of the HIPS prefabricated material is treated by ultraviolet cross-linking modification of the polyvinyl alcohol, the [3-(2,3-epoxypropoxy)propyl]trimethoxysilane and the ethylene diamine to obtain the modified HIPS composite material with a hydrophilic surface, and the material has the advantages of fog resistance, lipophobicity and antistatic properties.

Description

technical field [0001] The invention relates to the field of modification of polymer materials, and more specifically relates to a preparation method of a modified HIPS composite material. Background technique [0002] Polystyrene has the advantages of excellent formability, rigidity, transparency, and low hygroscopicity. High-impact polystyrene (HIPS) is prepared by mixing a small amount of elastomer into PS. HIPS material overcomes polystyrene material. Due to the disadvantage of low toughness, it is widely used in electronics, automotive interiors, home appliances and other fields. However, the surface resistance of ordinary HIPS materials is very high, and it is easy to be electrified by friction. The static electricity remaining on the surface of the material is difficult to remove, and it is easy to absorb dust. In severe cases, it is even easy to generate sparks, which poses a great safety hazard. Moreover, because of its translucency, HIPS materials are often used a...
