High- fluidity and high-impact ASA material and preparation method thereof

Abstract

The invention discloses a high-fluidity and high-impact ASA material and a preparation method thereof and belongs to the field of polymer composite materials. The ASA material comprises the following raw materials in percentage by weight: 60-80% of an acrylonitrile-styrene copolymer, 20-40% of an acrylonitrile-styrene-acrylate graft copolymer, 2-10% of a compatibilizer, 0.2-1% of an antioxidant and 0.2-2% of a light stabilizer. The ASA material prepared by the preparation method has high impact performance and good processing fluidity, is easy to fill molded large-size abrasive tools and can be widely applied to interior and exterior decorative parts of automobiles and parts of electronic electric appliances.

Description

Technical field [0001] The invention relates to a high-flow, high-impact ASA material and a preparation method thereof, in particular to a high-flow, high-impact ASA material that can be applied to automobile interior and exterior trim parts, electronic and electrical parts, and belongs to polymer modification and processing field. Background technique [0002] ASA resin is a ternary graft copolymer composed of acrylate-styrene-acrylonitrile. It has excellent comprehensive properties, good mechanical and physical properties, high temperature resistance, antistatic properties, and it has excellent weather resistance. Its weather resistance is about 10 times higher than that of ABS. It has a wide range of uses and is widely used in automobiles, electronic appliances, outdoor equipment and other fields. [0003] However, ASA material has low impact resistance, which limits its application in automotive exterior parts, such as car grilles. ASA material has poor fluidity and is not eas...

AI Technical Summary

Problems solved by technology

[0003] However, the impact resistance of ASA materials is low, which limits its application in automotive exterior parts, such as automotive grilles; Application of interior parts, such as car door panels, etc.

[0004] At present, the common measure to improve the impact resistance of ASA materials is to add PC resin. However, the disadvantage of this method is to further increase the difficulty of forming and processing ASA materials by adding PC.

In addition, in order to solve the problem of poor fluidity of ASA materials, the traditional solution is to appropriately increase the injection temperature in the injection molding process to improve its processing fluidity, but this also increases the processing cost virtually.
