Abstract

The invention relates to a dust-proof anti-aging black high-gloss ABS (acrylonitrile-butadiene-styrene) alloy which comprises the following components in percentage by weight: 48-60% of ABS resin, 22-30% of PMMA (polymethyl methacrylate) resin, 12-18% of compatilizer and 4-6% of dust-proof anti-aging high-gloss black master batch. The anti-aging agent and pigment carbon black in the dust-proof anti-aging high-gloss black master batch constitute an anti-aging system; and the carbon nanotubes, pigment carbon black and lauryl amine polyoxyethylene (2) ether constitute a dust-proof system, thereby effectively preventing aging of ABS, and satisfying the requirements of the high-gloss ABS alloy for coloration, color protection, gloss protection and dust-proofing. The preparation method comprises the following steps: preparing the dust-proof anti-aging high-gloss black master batch, and preparing the dust-proof anti-aging black high-gloss ABS alloy by using the master batch. The multifunctional master batch technique provided by the invention eliminates environmental pollution of dust, implements green clean production of the ABS resin and alloy, has the characteristics of low consumption of carrier resin and lubricating dispersant and low consumption of master batch processing energy and processing assistants, and can be widely applicable to formation processing of the ABS and alloy.

Description

technical field [0001] The invention relates to the technical field of polymer alloys, in particular to a dust-proof and aging-resistant black high-gloss ABS alloy and a preparation method thereof. Background technique [0002] ABS resin obtained by ternary copolymerization of acrylonitrile, butadiene, and styrene is widely used in the electronics and electrical industries due to its excellent comprehensive properties. High-gloss ABS alloys occupy a large share in high-gloss plastics. The high-gloss ABS alloy realizes the ABS spray-free process, which is a new technology for energy saving and environmental protection in the electronic and electrical industry. [0003] The main chain of ABS resin contains double bonds, which is one of the most prominent plastics with aging problems. Poor aging resistance is one of the biggest shortcomings of ABS. The earliest aging phenomenon during product use is loss of gloss (loss of gloss), so it is particularly important for gloss reten...
