Acrylonitrile butadiene styrene (ABS) with controllable photodegradation speed and preparation method thereof

Abstract

The invention relates to acrylonitrile butadiene styrene (ABS) with a controllable photodegradation speed and a preparation method. The ABS with the controllable photodegradation speed is obtained through melt mixing of ABS master batches and composite photocatalysts of nanometer titanium dioxide and fluorine or nanometer titanium dioxide, fluorine, manganese, copper or aluminum according to a mass ratio of 91 to 98 / 2 to 9. After the addition of the photocatalysts, any adverse effect is not generated on the processing performance and the use performance of products. The invention solves the problems of nondegradation and degradation speed of the ABS in the natural light state. Because the ABS has low price and large market consumption, but the nondegradation is caused through the stability of the ABS, and higher environment load is caused after the ABS is abandoned.

Description

Technical field [0001] The invention relates to an ABS formula, in particular to an ABS with a controllable photodegradation rate and a preparation method thereof. Background technique [0002] ABS (acrylonitrile-styrene-butadiene copolymer) has been widely used due to its excellent properties, but the environmental pressure caused by its stability continues to increase. The post-treatment of ABS has particularly problems. Tricky. Although methods such as landfilling, burning and recycling can be adopted, the existing research results and industrial practice have proved that these methods have varying degrees of drawbacks. Because of its excellent properties, ABS has been widely used in various fields, but the non-degradability of ABS and the environmental load caused by disposal are one of the problems facing humans. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned existing problems in the prior art, and to provide an ABS wi...
