Method for preparing little odor acrylonitrile-butadiene-styrene ternary copolymerized resin material using odor agglomerate

Abstract

The invention relates to a method for preparing little odor acrylonitrile-butadiene-styrene ternary copolymerized resin material by utilizing odor agglomerate, which can effectively reduce the bad smell in ABS composite material, and is prepared from the following raw material (by weight percent), base resin 20-70, odor depressant 30-80, wherein the base resin comprises (by weight ratio) rubber 5-30%, acrylic nitrile 10-30%, phenylethene 40-70%, the odor depressant is alkali metal aluminosilicate powder, or one or combination of silica gel materials.

Description

technical field

[0001] The present invention relates to a method for preparing low-odor acrylonitrile-butadiene-styrene terpolymer resin (ABS) material by using odor masterbatch, more specifically relates to the odor that can effectively suppress the unpleasant odor in the ABS composite material The inhibitor and the matrix resin are first made into a high-concentration odor masterbatch, then sealed, and finally mixed with the ABS material when the ABS material is molded to form a low-odor ABS material. Background technique

[0002] Styrene acrylonitrile copolymer, namely ABS (acrylnitrole-butadiene-styrene copolymer), is a copolymer of acrylonitrile-butadiene-styrene, which is the most developed and changed variety among styrene series resins. Due to the advanced performance Compared with other resins, ABS has undoubted advantages and competitiveness due to its relatively low price. Therefore, ABS with various characteristics has been continuously developed and applied, whi...
