Abstract

The invention discloses an oil-resistant high-gloss polystyrene material and a preparation method and application thereof. The oil-resistant high-gloss polystyrene material comprises high-impact polystyrene, high-density polyethylene, an interface improving agent and an antioxidant according to a certain proportion, the interface improving agent is a vinyl and dialkenyl thermoplastic elastomer with a certain molecular weight, the oil-resistant high-gloss polystyrene material uses the high impact polystyrene as the base material, has high gloss, further contains the high density polyethylene and the interface improving agent, and further uses a parallel twin-screw extruder with weak shearing to perform extrusion granulation so as to prepare the modified high impact polystyrene, meanwhile,the oil resistance, high glossiness and toughness are higher, and the material can be widely applied to the fields of electric appliances, office supplies, toys, packaging materials and the like.

Description

technical field [0001] The invention relates to the technical field of oil-resistant and high-gloss modified polymer materials, and more particularly, relates to an oil-resistant and high-gloss polystyrene material and its preparation method and application. Background technique [0002] High-impact polystyrene (HIPS) is a two-phase system consisting of a rubber phase and a continuous polystyrene phase. Its special "sea-island structure" endows the material with excellent toughness and rigidity, good processability and dimensional stability , Has been widely used in household appliances, electronic appliances, office, toys and packaging and other fields. In many applications, HIPS requires a high-gloss surface to improve the appearance and grade of the product. However, high-gloss HIPS has poor oil resistance and will come into contact with oily substances in some environments, especially when used in For kitchen utensils, such as refrigerators, due to the weak polarity of ...
