Problems solved by technology

However, the molecular structure of ABS determines that it is a poor conductor, and it is easy to accumulate a large amount of static charge during use.
The electrostatic attraction is easy to absorb dust and some dirt in the air, which affects the appearance of the product; especially when the static electricity accumulates to a certain extent, static spark discharge may occur, causing some catastrophic accidents

Abstract

The invention discloses a transparent ABS material and a preparation method thereof. The transparent ABS material comprises the following components by weight percentage: 90-95 percent of ABS, 2-5 percent of main anti-static agent, 1-3 percent of auxiliary anti-static agent and 1-2 percent of high-temperature antioxidant. The transparent ABS material maintains the advantages of the ABS such as easy processing and formation, excellent corrosion resistance, excellent chemical resistance and the like, and also has the advantages of excellent transparency, excellent anti-static effect and permanent anti-static properties. Therefore, the transparent ABS material can substitute glass in various fields, and has broad application prospects in such industries as electrical appliances, instruments,automobiles, medical appliances and electronics.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a transparent ABS material and a preparation method thereof. [Background technique] [0002] Acrylonitrile-butadiene-styrene copolymer (Acrylonitrile ButadieneStyrene, ABS) is currently the largest and most widely used polymer. It organically unifies the various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigid phase balance. It has excellent impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, good molding and machining. However, the molecular structure of ABS determines that it is a poor conductor, and it is easy to accumulate a large amount of static electricity during use. The electrostatic attraction is easy to absorb dust and some dirt in the air, which affects the appearance of the product; especially when the static electricity accumulates ...
