Problems solved by technology

However, the above methods generally cost relatively high, and will reduce the toughness of the material itself to a certain extent.
[0005] The high-impact polystyrene resin HIPS with large particle size has a very low gloss when the particle size is above 5um, and the material price ratio is relatively low. However, due to the poor compatibility between HIPS and ABS materials, it is not used as a material at present. Related reports of ABS matte agent

Abstract

The invention provides a low-gloss heat-proof ABS (Acrylonitrile Butadiene Styrene) resin and a preparation method thereof. The ABS resin is prepared from the following components in parts by weight: 65-94 parts of acrylonitrile-butadiene-styrene resin, 5-25 parts of heat-proof agent, 1-10 parts of matte masterbatch and 0.1-1 part of accessory ingredient. Compared with the prior art, the low-gloss heat-proof ABS resin is characterized in that the matte masterbatch which takes large particle size HIPS (High Impact Polystyrene) as a main body is added into the heat-proof ABS resin, the compatibility of the HIPS and the ABS is improved through SBS (Styrene-Butadiene-Styrene) flexibilizer and the compatilizer of a core-shell structure, surface gloss is obviously lowered on a premise that the toughness is not affected, cost is relatively low, and the low-gloss heat-proof ABS resin can be applied to automobile interior trim parts which have a matte requirement.

Description

technical field [0001] The invention relates to a modified resin, in particular to a low-gloss heat-resistant ABS resin and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer (ABS) is a common general-purpose resin. ABS has excellent characteristics such as high toughness, easy processing, and easy coloring. Its comprehensive performance is good, and it is widely used in automobiles, electronics, military, machinery and other industries. With the development of modern technology, the demand for ABS is also growing rapidly, especially in the automotive industry. With the increase in car sales, the amount of ABS is also increasing. [0003] Automotive interior parts are generally required to use materials with relatively low gloss in order to avoid potential safety hazards caused by strong light and visual pollution to drivers caused by sunlight reflection. The gloss of ABS resin is mainly determined by the particle size of...
