Abstract

The invention specifically relates to a high-rigidity high-gloss modified polystyrene material, which belongs to the technical field of modified polystyrene materials. The material comprises the following raw materials: high impact polystyrene, general-purpose polystyrene, a stabilizing agent, white oil and a dye. According to the invention, high impact polystyrene is modified, and the performances of high rigidity and high gloss are obtained.

Description

Technical field [0001] The invention belongs to the technical field of polystyrene modified materials, and specifically relates to a high-rigidity and high-gloss polystyrene modified material. Background technique [0002] The polystyrene material synthesized from styrene monomer through radical condensation reaction is usually called general-purpose polystyrene (GPPS), which is a colorless and transparent general-purpose plastic with low price and excellent thermal insulation, insulation and Transparency, but because of its brittleness and easy cracking and low impact strength, its application is greatly limited. Therefore, high impact polystyrene (HIPS) is prepared by copolymerization of diene rubber and styrene monomer, which improves the toughness of polystyrene materials and broadens the application fields of polystyrene materials. Polystyrene (HIPS) has been widely used in industries such as electronics, electrical appliances, instrumentation, packaging, and daily necessit...
