Abstract

Belonging to the technical field of high polymer materials, the invention relates to an ABS / PC (acrylonitrile-butadiene-styrene / polycarbonate) material and a preparation method thereof. The ABS / PC material comprises the following components by weight: 100 parts of ABS resin, 10-50 parts of PC resin, 15-80 parts of glass fiber, 5-20 parts of a compatibilizer, 0.2-1.5 parts of an anti-glass fiber exposure agent, and 0.3-1.0 part of an antioxidant. The ABS / PC material provided by the invention has excellent extrusion molding performance, the weather resistance, oil resistance, solvent resistance and physical and mechanical properties are obviously superior to those of unmodified ABS materials, and the extruded products have the characteristics of smooth surface, no floating fiber, and excellent performance, thus being widely applicable in pipelines, building profiles, sheet materials and every field of social life and having great economic and social value.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an ABS / PC material for high-gloss extrusion technology and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) is widely used in various fields of social life because of its excellent mechanical properties, dimensional stability, easy processing, coloring, and convenient post-processing. One of the wide range of polymers. At the same time, ABS has the advantages of high melt strength, excellent chemical resistance, good extrusion performance, and low price. But at the same time, ABS plastic also has disadvantages such as low heat distortion temperature, poor weather resistance, relatively high impact strength and tensile strength, which limit its application. [0003] Polycarbonate (PC) is an amorphous thermoplastic polyester with the advantages of non-toxicity, good weather resistance, high mechanical strength, outstanding ...
