HIPS/PP (high impact polystyrene/polypropylene) alloy plastic with high gloss and excellent oil resistance and preparation method thereof

Abstract

The invention relates to an HIPS / PP (high impact polystyrene / polypropylene) alloy plastic with high gloss and excellent oil resistance and a preparation method thereof. The HIPS / PP alloy plastic is prepared from the following components and raw materials in parts by weight: 45-90 parts of general purpose polystyrene, 5-45 parts of co-polypropylene, 5-35 parts of a flexibilizer, 1-10 parts of a compatilizer, 0.1-2.5 parts of an antioxidant and 0-2.5 parts of other aids. The preparation method comprises the following steps: stirring the raw materials in a high-speed mixer, uniformly mixing, feeding the materials into a twin-screw extruder through a metering device for extruding, drawing, cooling and dicing, thereby obtaining the HIPS / PP alloy plastic with high gloss and excellent oil resistance. Compared with the prior art, the HIPS / PP alloy plastic disclosed by the invention can effectively overcome the defect that the HIPS-related material is high in oil resistance while low in gloss, so that refrigerator inner liners and other HIPS-related products with oil resistance requirements can be widely applied to various household appliance outer parts. According to the alloy plastic disclosed by the invention, a technical support can be provided for producing engineering plastic products which have higher performances and can be manufactured into the outer parts.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high-gloss and oil-resistant HIPS / PP alloy plastic and a preparation method. Background technique [0002] Because of its many excellent properties, such as low density, convenient processing, and low price, HIPS materials are more and more used in people's daily life products, especially in various appearance and structural parts of home appliances. However, HIPS materials also have many disadvantages, such as low gloss, poor chemical resistance (oil resistance), easy cracking and flammability, etc. These are the difficulties that people need to consider and overcome when using HIPS related products. [0003] In recent years, some co-extruded HIPS alloy plastics with high oil resistance and high gloss have been widely used in the appearance or structural parts of products, such as refrigerator liners. These parts are generally made of a layer of HIPS with good gloss but poor ...
