Abstract

The invention belongs to the technical field of polystyrene modified materials, and concretely relates to a polystyrene resin with high rigidity and high gloss and a preparation method therefor. The composition is composed of the following raw materials: high impact polystyrene, general purpose polystyrene, stabilizing agents, processing aids and dyes. The preparation method comprises the steps of mixing, extrusion and granulation. High impact polystyrene is modified, and 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 in particular relates to a high-rigidity and high-gloss polystyrene resin and a preparation method thereof. Background technique [0002] The polystyrene material synthesized by free radical polycondensation of styrene monomer 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 its application is greatly limited due to its brittleness and low impact strength. Therefore, people use diene rubber and styrene monomer to copolymerize high-impact polystyrene (HIPS), which improves the toughness of polystyrene materials and broadens the application fields of polystyrene materials. Polystyrene (HIPS) has been widely used in electronics, electrical appliances, instruments, packaging, daily necessities and other industries. [0003] Ho...
