Abstract

The invention relates to a high molecular polycarbonate alloy material and a preparation method thereof. The alloy material comprises the following raw materials in parts by weight: 60 to 80 parts of PC, 20 to 30 parts of ABS, 1 to 4 parts of compatibilizer a, 1 to 4 parts of compatibilizer b, and 0.2 to 0.4 part of antioxidant, wherein the compatibilizer a and compatibilizer b are maleic anhydride grafted polyethylene, and the softening point of the polyethylene for grafting is not higher than 85 DEG C. The preparation method comprises the following steps: at first, blending PC and the compatilizer a once, extruding the mixture to obtain PC / PE-g-MAH, then fully mixing PC / PE-g-MAH with ABS, the compatilizer b, and an antioxidant in a high speed mixing machine, extruding the mixture by a dual screw extruder, and finally carrying out secondary melting and granulation to obtain the high molecular polycarbonate alloy material. The prepared polycarbonate alloy has a stable property and an excellent performance on resisting impact. The phenomenon of severe layering and cracks on the surface during the processing process are improved.

Description

Technical field [0001] The invention relates to the technical preparation field of polycarbonate alloys, in particular to a polymer polycarbonate alloy material and a preparation method thereof. Background technique [0002] The blend with ABS and PC as the main raw material is an important engineering plastic alloy. It has the advantages of ABS and PC, that is, it has good molding fluidity and high heat distortion temperature and stability. Compared with PC, it reduces the melt viscosity, improves the processing performance, improves the low-temperature impact strength and reduces the thickness sensitivity and price; compared with ABS, it increases the heat distortion temperature and improves its mechanical properties, and it has better performance It is widely used in automobile, electronics and office machine tool manufacturing industries. [0003] However, there is a benzene ring structure in PC, and the styrene content of the main component SAN in ABS is generally more than 7...
