Abstract

The invention relates to the field of polymer materials, specifically a PC / ABS alloy with no pitting, high weather resistance and high black and bright spray-free effect, which is composed of the following components in parts by weight: 40-80 parts of PC resin, 20-60 parts of ABS resin 0.1 to 1 part of lubricant, 0.1 to 1 part of antioxidant, 0.1 to 5 parts of PMMA carbon black masterbatch; the PMMA carbon black masterbatch is composed of the following components according to the following weight percentage: MMA monomer 20~60 %, carbon black 5-30%, dispersant 0.1-2%, emulsifier 0.1-5%, initiator 0.1-2%, deionized water 30-50%. The invention provides a PC / ABS alloy with no pitting, high weather resistance and high black and bright spray-free effect and a preparation method thereof, which can also achieve the high gloss black effect and weather resistance requirements without spraying high-gloss paint, so as to meet the requirements of automobile The interior has a high-gloss black exterior effect.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PC / ABS alloy with no pitting, high weather resistance and high black and bright spray-free effect and a preparation method thereof. Background technique [0002] Polycarbonate / acrylonitrile-butadiene-styrene copolymer (PC / ABS) has excellent mechanical properties, heat resistance, etc., and is a widely used engineering plastic. At present, the design of the central control panel of the car interior tends to have a high-gloss black effect. In order to achieve this high-gloss black effect, it is usually achieved by spraying high-gloss paint. However, the comprehensive cost of spraying high-gloss paint will increase by 40%, and the odor and VOC often fail to meet the requirements of the OEM. Therefore, it is of great significance to develop a PC / ABS alloy with no pitting, high weather resistance and spray-free effect. [0003] Usually the color of high-black and bright products is...
