ABS resin composition capable of maintaining high glossiness in thermoforming and ABS sheet using same

Abstract

Disclosed are an ABS resin composition and an ABS sheet using the same, wherein the ABS resin composition has an excellent surface quality and enables the manufacture of a sheet with excellent glossiness even in thermoforming. The ABS resin composition according to the invention comprises a) 50-80 weight% of an acrylonitrile-butadiene-styrene (ABS) resin, b) 10-30 weight% of a styrene-acrylonitrile (SAN) copolymer, and c) 10-20 weight% of a rubber resin, wherein the ABS resin is a bulk polymerization-type ABS resin.

Description

technical field [0001] The present invention relates to the preparation technology of ABS (Acrylonitrile-Butadiene-Styrene, acrylonitrile-butadiene-styrene) sheet, more specifically, relate to ABS resin composition and utilize the ABS sheet of this ABS resin composition, it and present Some sheets made of ABS resin have superior surface quality, and high gloss can be ensured even during thermoforming. Background technique [0002] ABS resins are broadly classified into bulk polymerized ABS resins, emulsion polymerized ABS resins, and suspension polymerized ABS resins. Among them, the most widely used are bulk polymerized ABS resin and emulsion polymerized ABS resin. [0003] ABS resin has different physical properties and characteristics according to its different polymerization methods. [0004] If a bulk polymerized ABS resin is used to manufacture a thin sheet exhibiting optical properties, the surface quality is excellent due to less gel, but when thermoforming is perf...

Problems solved by technology

[0005] On the contrary, if an emulsion-polymerized ABS resin is used to manufacture a sheet exhibiting optical properties, the rubber particles can exhibit optical properties due to the small size, and especially during thermoforming, the optical properties can also be maintained to some extent. Although there are such advantages, the emulsifiers and coagulants that must be used in the characteristics of the emulsion polymerization process cannot be completely removed in the coagulation and dehydration process, but remain on the final product, resulting in a decrease in physical properties, and A large amount of gel forms on the surface of the flake

[0006] Therefore, up to now, no matter whether it is the case of using bulk polymerized ABS resin or the case of using emulsion polymerized ABS resin, the surface quality and high gloss cannot be satisfied.
