Problems solved by technology

[0002] At present, there are many high-impact polystyrene resins (HIPS) that are close to ABS and other engineering plastics in some properties, but have great advantages in price and processing performance, so HIPS also has certain advantages in the application field of engineering plastics. For example, some electronic and electrical industries such as TV casings, monitors, copiers, fax machines, printers, and refrigerators are continuously increasing the amount of HIPS resin used, but ordinary HIPS is poor in gloss and cannot meet certain requirements. The device requires glossiness in appearance, but the price of high-gloss HIPS on the market is relatively expensive. The present invention is aimed at this situation, and produces a kind of glossiness that is higher than ordinary HIPS, but the cost is relatively low. Moreover, it has little effect on the material performance and can improve the processing fluidity of the HIPS resin. The material has the characteristics of high impact strength, good appearance, and good processing and molding. The key point is that the material has excellent gloss and good appearance, and can be used for injection molding. Forming various occasions such as home appliance casings or bases that have relatively high requirements on the appearance of HIPS

Abstract

The invention belongs to the technical field of alloy materials and relates to a high impact polystyrene (HIPS) resin material with excellent glossiness. The HIPS resin material with excellent glossiness comprises the following components by weight: 50 to 90 parts of high impact polystyrene resin, 10 to 50 parts of general polypropyl ethylene resin, 0.1 to 1 part of photo-thermal stabilizer and 0.1 to 1 part of processing aid. The HIPS resin material with excellent glossiness is prepared by a double-screw extrusion process, has the advantages of simple and continuous flow, high production efficiency and stable product quality; the glossiness is improved; the processing flowability is well improved; the reducing fluctuation of mechanical performance is small; influence on other performance of the material is avoided; and the characteristics of high impact strength, good appearance, high processing formation and the like are obtained. The key point is that: the material has excellent glossiness and good appearance and can be applied to injection molding of various shells or pedestals of household appliances and the like with relatively high requirement on the HIPS appearance.
