Problems solved by technology

[0003] Although ABS has many excellent properties and has become one of the most used polymer materials at present, due to the volatility of ABS, commonly used ABS products often produce certain volatiles during use, which will produce certain volatile substances on the surface of the parts. Distributed matter affects the use of parts, and also produces a certain unpleasant smell, which has a negative impact on the air—especially the air quality of some indoor spaces, and causes certain damage to the health of users and environmental protection.
With the increasingly higher requirements for people's environmental protection and physical and mental health, ABS has certain hidden dangers in the use process due to the unpleasant smell caused by its volatility, which greatly limits the development of ABS. Detection and Control

Abstract

The invention provides low-odor ABS engineering plastic, which is characterized in that the ABS engineering plastic contains, by weight percentage, 60 to 94.5 percent of ABS resin, 5 to 37.5 percent of modifier, 0.1 to 0.5 percent of antioxidant, 0.1 to 0.5 percent of lubricant, 0.15 to 0.5 percent of sodium aluminosilicate, and 0.15 to 1.0 percent of castor oil zinc salt. The method for preparing the low-odor ABS engineering plastic comprises the following steps: weighing above materials according to a certain ratio, mixing uniformly in a high-speed mixer, and extruding and granulating in a double-screw extruder. The method can reduce the odor of general plastic and at the same time keep the original properties of the ABS engineering plastic.

Description

technical field [0001] The invention relates to a preparation method of low-odor ABS engineering plastics. Background technique [0002] ABS resin was first introduced by the American Rubber Company. It has the characteristics of high impact strength, good dimensional stability, excellent electrical properties, excellent wear resistance and good molding performance, so it has become Ideal material for automotive components such as dashboards. [0003] Although ABS has many excellent properties and has become one of the most used polymer materials at present, due to the volatility of ABS, commonly used ABS products often produce certain volatiles during use, which will produce certain volatile substances on the surface of the parts. The emitted matter affects the use of the parts, and also produces a certain unpleasant smell, which has a negative impact on the air—especially the air quality of some indoor spaces, and causes certain damage to the health of users and environme...
