Problems solved by technology

[0008] Although there are many reports on scratch-resistant materials, there is still no good report on the scratch resistance of PC / ABS.
Such as CN105623233A, the introduction of calcium carbonate will lead to the decline of mechanical properties, and at the same time, the improvement of scratching behavior is limited; although CN107674396A can improve the hardness by introducing PMMA, there are still obvious problems of compatibility and scratches; and CN105778232A Fluorinated ethylene propylene, polyvinylidene fluoride or ethylene tetrafluoroethylene copolymers are used in PE, but these substances are not compatible enough in the PC / ABS matrix on the one hand, and secondly, due to their low hardness, they are still very Easily scratched by nails, hard objects, etc.

Abstract

The invention provides a PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) alloy with scratch resistance and a preparation method thereof. The PC / ABS alloy comprises, by weight, 30-80 parts of PC, 15-60 parts of ABS, 1-20 parts of polyvinylidene fluoride masterbatch, 0.5-5 parts of a compatibilizer, 2-15 pats of a toughener, 0.1-1 part of an antioxidant, and 0.1-1 part of a lubricant. The preparation method comprises preparing the materials by weight, adding the materials into a medium-speed mixer except for the polyvinylidene fluoride masterbatch, mixing for 5-30 min to obtain a mixture,adding the mixture into a twin-screw extruder under controlled speed of 180-600 rpm, feeding the polyvinylidene fluoride masterbatch from the lateral side, melting and extruding, and granulating to obtain the finished PC / ABS alloy. Compared with the prior art, the PC / ABS alloy with scratch resistance provided herein has high processibility and high scratch resistance.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PC / ABS alloy with scratch resistance and a preparation method thereof. Background technique [0002] PC / ABS alloy is a common engineering plastic alloy product. Due to its high heat resistance and excellent mechanical properties, it is widely used in automobiles, electronics, home appliances and other fields. However, as PC / ABS is more and more used in surface decoration parts, the requirements for aesthetics are getting higher and higher. At the same time, because decorative parts are often touched or touched, the scratch resistance of the material is also paid more and more attention. . [0003] Currently, there are many scratch-resistant patents. [0004] For example, Hu Senchuan et al. described in the CN105623233A patent that the wear resistance and scratch resistance of PC / ABS alloys can be improved by modifying calcium carbonate. [0005] Jiantian Maoxing described in...
