Abstract

The invention relates to a low-odor acrylon-butadiene-styrene copolymer resin material and its preparing process, wherein the material comprises (by weight portions) ABS100, porous silica gel material 0.5-5, toughening agent 0-5, anti-oxidant 168 0.1-1.0, anti-oxidant 245 0.1-1.0, ultraviolet absorbent 0-2.0, free radical quenching agent 0-2.0, wherein the the ABS comprises rubber 5-30 wt%, acrylic nitrile 10-30%, phenylethene 40-70%, the porous silica gel material is a silicon oxide porous powder material with a grain size greater than 200 meshes, and a micropore diameter between 20-30A. The toughening agent is a high-colloidal ABS.

Description

technical field [0001] The present invention relates to a kind of low-odor acrylonitrile-butadiene-styrene terpolymer resin (ABS) material, more specifically relate to by adding a kind of odor inhibitor that can effectively suppress the unpleasant smell in the polypropylene composite material, Thereby preparing a kind of low smell ABS material. [0002] The invention also relates to a method for preparing the composite material. Background technique [0003] 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, which makes ABS the most widely used variety in engineering plastics. It is u...
