Abstract

The invention discloses a blow-molded PC/ABS composite material with high heat resistance and high melt strength and a preparation method therefor. The composite material is prepared from the following raw materials in percentage by weight: 35% to 60% of polycarbonate, 20% to 40% of SAN, 5% to 20% of melt reinforcer, 5% to 20% of toughener, 5% to 10% of compatibilizer, 0.4% to 1% of antioxidant and 0.4% to 1% of lubricant. The composite material and the preparation method therefor have the advantages that the PC/ABS composite material prepared by the method can be subjected to blow molding toproduce various parts of complicated structures; the melt strength of the prepared blow-molded PC/ABS composite material is obviously improved, and thus, the thickness of products can be uniform; andthe blow-molded PC/ABS composite material with high heat resistance and high melt strength, disclosed by the invention, is relatively simple in preparation process, has the characteristics of high heat resistance, high melt strength and the like and can be applied to automobile tail wings, spoilers and the like.

Description

technical field [0001] The invention relates to a high heat resistance, high melt strength blow molding PC / ABS composite material, specifically a blow molding PC / ABS composite material with high heat resistance and high melt strength, and the composite The method of preparation of the material. Background technique [0002] Car tail fins and spoilers are generally blow-molded. This molding method can produce various complex and irregular monolithic products. When injection molding is used, two or more products need to be produced first. Finally, they are assembled together by snap fit or ultrasonic welding. [0003] Generally, ABS materials are difficult to balance impact and heat resistance, and the parts are easy to be brittle or not resistant to high temperature; while PC / ABS has an excellent balance of mechanical properties, and it also has high impact performance at low temperatures. Moreover, the addition of PC can make the melt strength of the material higher and ea...
