Weather-resistant, bending-resistant, high-gloss and low-light-transmittance ABS material and preparation method thereof

Abstract

The invention discloses a weather-resistant, bending-resistant, high-gloss and low-light-transmittance ABS (Acrylonitrile Butadiene Styrene) material. The key point of the technical scheme is that the weather-resistant, bending-resistant, high-gloss and low-light-transmittance ABS material contains the following components in percentage by mass: 79-91wt% of weather-resistant ABS resin, 0.2-0.4wt% of a dispersant, 0.2-0.4wt% of an antioxidant, 0.3-0.6wt% of a lubricant, and 8-20wt% of a light-screening agent. The weather-resistant, bending-resistant, high-gloss and low-light-transmittance ABS material provided by the invention is relatively good in shading effect, better in weather resistance and fluidity and lower in cost.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of macromolecules, and in particular relates to an ABS material with weather resistance, bending resistance, high gloss and low light transmittance and a preparation method thereof. [0003] 【Background technique】 [0004] Acrylonitrile-butadiene-styrene copolymer is a terpolymer composed of acrylonitrile, butadiene and styrene, referred to as ABS. ABS has good chemical resistance, high notched impact strength, good processing fluidity, excellent gloss, excellent coloring and good electroplating performance, but it is exposed to ultraviolet light for a long time due to its double bond Yellows and becomes brittle when exposed to light. To improve the weather resistance of ABS resin, a relatively simple method is to add antioxidants, ultraviolet absorbers and light stabilizers to ABS resin, but the weather-resistant ABS produced by this method only has a short-term weather resistance effect, and it wi...
