Problems solved by technology

However, on the one hand, spraying paint will greatly increase the processing cost of plastic parts, and on the other hand, the amount of VOC released during the spraying process will increase, causing environmental pollution
[0005] The current technical solutions often have defects such as large fluctuations in physical and mechanical properties, insufficient blackness, poor appearance, and high cost; ultra-black, bright, high-gloss, scratch-resistant ABS materials that can directly replace painting effects have not yet been reported.

Abstract

The invention provides an ultra-black bright high-gloss scratch-resistant ABS compound as well as a preparation method and application thereof. The ultra-black bright high-gloss scratch-resistant ABScompound comprises the following components in percentage by mass: 12-54% of AS; 15-20% of high glue powder; 20-60% of PMMA; 5-20% of MABS; 0.1-1% of a high-blackness toner; 0.3-1% of an antioxidant;and 0.1-1% of a processing aid; the high-blackness toner is a compound of inorganic black powder and organic black powder; and the mass ratio of the inorganic black powder to the organic black powderin the compound is (5-30): (21-106). The ABS compound provided by the invention has the characteristic of high blackness, and the blackness value (L value) of the material can be controlled within therange of less than 26.2.

Description

technical field [0001] The invention belongs to the technical field of ABS materials, and in particular relates to an ultra-black, bright, high-gloss, scratch-resistant ABS compound, its preparation method and application. Background technique [0002] ABS (Acrylonitrile butadiene Styrene) resin is a terpolymer with excellent comprehensive properties composed of acrylonitrile, butadiene and styrene. Because of the synergistic performance of the three components, ABS resin has good fluidity, toughness, good low temperature impact resistance, good creep resistance, good dimensional stability, small molding shrinkage, good gloss, and excellent formability. It is widely used in household appliances, mechanical parts, office supplies, electronic devices, automobile industry and other fields, and has become the mainstream plastic raw material favored by major enterprises and research institutions. [0003] With people's pursuit of high-quality life, the noble, elegant, and stable...
