Abstract

The invention discloses a high-gloss scratch-resistant ABS / PVC (acrylonitrile-butadiene-styrene / polyvinyl chloride) alloy and a preparation method thereof. The alloy comprises ABS, PVC, PMMA (polymethyl methacrylate), toughening agent, assistant, stabilizer, lubricant and antioxidant. The ABS / PVC alloy is balance in mechanical property, excellent in flame retardancy, easy to machine, low in cost, easy to color, scratch-resistant, high in surface hardness, and is applicable to high-gloss and scratch-resistant products such as electronic appliances, automobiles and machinery.

Description

technical field [0001] The invention belongs to the field of polymer modification, and in particular relates to an ABS / PVC alloy and a preparation method thereof. [0002] Background technique [0003] Acrylonitrile-butadiene-styrene terpolymer (ABS) and polyvinyl chloride (PVC) are currently the most widely used general-purpose plastics in the world, among which the amount of PVC ranks second in the world, and ABS ranks fifth. PVC has good physical and chemical properties, excellent chemical stability, flame retardancy and electrical insulation, but its processing performance is poor; while ABS has excellent comprehensive properties and toughness, easy to color and process, but The flame retardant performance is poor. Combining ABS and PVC can not only combine the comprehensive properties of the two, but also make up for the weaknesses of the two. [0004] ABS / PVC alloy has been widely used in household appliances, electronic appliances, automobiles, machinery and other ...
