Problems solved by technology

[0003] On some parts of the car, in order to achieve a high-gloss effect, the usual practice is to spray high-gloss paint on the plastic substrate, but the spray paint is not only expensive to process, but also not conducive to environmental protection. With the introduction of the automobile ELV law, more and more The thermoplastic material can be directly recycled without the need for the process of separating the thermosetting paint film

Abstract

The invention relates to a scratch-resistant high-light PC / ABS (Polycarbonate / Acrylonitrile-Butadiene-Styrene) material and a preparation method thereof. The scratch-resistant high-light PC / ABS material disclosed by the invention comprises 60-80% of PC resin, 3-8% of ABS resin, 5-25% of AS resin, 3-8% of a scratch-resistant agent, 3-6% of a compatilizer and 0.2-0.4% of antioxidant. The preparation method disclosed by the invention comprises the following steps: adding various components into a mixing barrel according to the mixture ratio to mix uniformly; adding the mixture into a double-screw extruder to mix, wherein the extrusion temperature of the first section and the second section of the double-screw extruder is 220-230 DEG C; the extrusion temperature of other sections is 240-270 DEG C; the rotation speed of a screw is 300-420 rpm; and finally, cooling and cutting after extruding the material so as to obtain the scratch-resistant high-light PC / ABS ally material. The scratch-resistant property of the high-light PC / ABS is improved by adopting the scratch-resistant agent; therefore, the scratch-resistant property of the high-light PC / ABS ally is increased; and thus, the scratch-resistant high-light PC / ABS material can be applied to real spraying-free automobile parts.

Description

technical field [0001] The invention relates to a modified resin and a preparation method thereof, in particular to a scratch-resistant high-gloss PC / ABS material and a preparation method thereof. Background technique [0002] With people's attention to the energy crisis, the energy saving and emission reduction of automobiles is the development requirement of today's automobile industry. Among them, the lightweight of automobiles, "replacing steel with plastic" has become an important development direction of today's automobile industry, so it provides a great opportunity for the development of the plastics industry. A good opportunity, but also higher and higher requirements for plastic performance. [0003] On some parts of the car, in order to achieve a high-gloss effect, the usual practice is to spray high-gloss paint on the plastic substrate, but the spray paint is not only expensive to process, but also not conducive to environmental protection. With the introduction ...
