Dust-proof anti-aging black high-gloss ABS (acrylonitrile-butadiene-styrene) alloy and preparation method thereof

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.
