Problems solved by technology

[0003] The traditional toughening modification is only a blended elastomer. Although the modification effect is very good, the impact strength can be increased several times to dozens of times, but the rigidity and heat resistance of the material are sacrificed while toughening.

Abstract

The invention belongs to the field of polystyrene sheets and particularly relates to a polystyrene sheet and a preparation method thereof. The polystyrene sheet comprises the following materials in parts by weight: 85-90 parts of polystyrene, 7-9 parts of black master batches, 7-9 parts of a filling agent, 6-8 parts of a toughening agent, 0.5-1 part of a dispersing agent and 0.1 part of an antistatic agent, wherein the toughening agent is a mixture of ABS (Acrylonitrile Butadiene Styrene), SBS (Styrene Butadiene Styrene) and talcum powder according to the weight ratio of 4:3:1. The particle size of the talcum powder is 50-100nm. Compared with the traditional polystyrene sheet, the polystyrene sheet obtained by adopting a formula of the invention is better in property, has the excellent properties of easy stacking, good light transmittance and high toughness, and has the advantages that the application range of the polystyrene sheet is expanded and more application requirements for customers can be better met.

Description

technical field [0001] The invention belongs to the field of polystyrene sheets, and in particular relates to a polystyrene sheet and a preparation method thereof. Background technique [0002] Traditional polystyrene materials have many shortcomings, such as brittleness, low impact strength, easy to crack, poor flame retardancy, poor weather resistance, low heat distortion temperature, etc., and are not easy to stack, low light transmittance, The shortcomings such as single color and not beautiful enough can not meet the increasingly broad application needs of customers. These shortcomings greatly limit the application range of polystyrene. Therefore, under the premise of not reducing the physical properties of polystyrene materials, it is urgent to improve the material production process to obtain biaxially oriented polystyrene with easy stacking, good light transmittance, and high toughness, which meets the current requirements. market demand. [0003] The traditional t...
