Embodiment Construction

[0019] The present invention will be specifically described below in combination with specific embodiments.

[0020] The technical solution provided by this embodiment is a high-rigidity and high-gloss polystyrene modified material, which includes the following raw materials: high-impact polystyrene, general-purpose polystyrene, stabilizers, white oil and dyes; The weight content of impact polystyrene is 75%-90%, and the weight ratio of general-purpose polystyrene to high-impact polystyrene is 1-3:10.

[0021] Wherein, the stabilizer is an antioxidant.

[0022] Wherein, the dyestuff is carbon black.

[0023] The preparation method of the above-mentioned high-rigidity and high-gloss polystyrene modified material provided by this embodiment has the following steps. Firstly, each raw material is stirred and mixed with a high-speed mixer, and then transferred to a twin-screw extruder for melting and extrusion, and cooled. Finally, the product can be obtained by granulation.

Abstract

The invention specifically relates to a high-rigidity high-gloss modified polystyrene material and a preparation method thereof, belonging 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. The preparation method comprises the following steps: mixing; extrusion; and granulation. 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 in particular relates to a high-rigidity and high-gloss polystyrene modified material 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. ...
