Embodiment

[0020] This embodiment includes the following steps:

[0021] 1) Preparation of PBT / PEG-g-MSA: First add phenol solvent to a three-necked flask equipped with a stirrer, a thermometer, and a reflux condenser, and dissolve 50 parts by mass of PBT / PEG block copolymer in carbon tetrachloride : In a solvent of xylene=1:1. Heat and stir, reflux until the PBT / PEG is completely dissolved, then add 10 parts of MMA, St and AN at 70°C, and then add 0.1 part of BPO, react at a constant temperature of 70°C for 8 hours, then cool the reaction system to 50°C and pour In a petri dish, dry to constant weight in a vacuum oven at 0.1 MPa and 50°C. The reaction product is in the form of a film. Cut the film into pieces, wrap it in filter paper, and extract it with phenol in a Soxhlet extractor for 20 hours to obtain the grafting ratio of PBT / PEG-g-MSA.

[0022] Preparation of surface-modified HGB: first add 10 parts by mass of HGB into deionized water, stir, filter, then add into absolute ethan...

Abstract

Provided are a highlight high-impact abrasion-resistant PC / ABS alloy and a preparation method thereof. The highlight high-impact abrasion-resistant PC / ABS alloy is formed by causing PC, ABS, PBT / PEG-g-MSA and silicone powder to be evenly mixed and then undergo melt blending with surface modification HGB. The PC / ABS alloy contains surface modification HGB and silicone powder, the 60-degree gloss (GU) reaches over 80, the cantilever beam notch impact strength reaches over 600J / m; the highlight high-impact abrasion-resistant PC / ABS alloy has the advantages of high gloss, high normal temperature impact and low temperature impact toughness and abrasion resistance, paint spraying secondary processing processes are reduced, and the highlight high-impact abrasion-resistant PC / ABS alloy is low in cost and has wide market value.

Description

technical field [0001] The invention relates to a modification technology in the field of polymer materials, in particular to a high-gloss high-impact wear-resistant modified PC / ABS alloy material and a preparation method thereof. The alloy material contains surface-modified HGB (HollowGlassBall hollow glass spheres) ) and silicone powder, the 60°gloss (GU) reaches more than 80, and the Izod notched impact strength reaches more than 600J / m. Background technique [0002] Polycarbonate (PC) is an engineering plastic with excellent performance. It has good comprehensive properties, high mechanical strength, good impact toughness, stable size, good heat resistance, and good electrical insulation; acrylonitrile-butadiene-benzene Ethylene copolymer (ABS), with excellent impact resistance, good low temperature performance and chemical resistance, good dimensional stability, good surface gloss, good fluidity, easy to process. PC / ABS alloy products not only retain the toughness, hea...
