Abstract

The invention discloses a glass fiber reinforced AES composite material and a preparation method thereof. The glass fiber reinforced AES composite material comprises the following ingredients by weight percent: 50-85% of AES resin, 5-30% of glass fiber, 3-8% of a compatilizer, 5-15% of a flexibilizer, 0.1-1% of an antioxidant, 0.5-2% of a coupling agent, and 0.5-1% of a lubricating agent. The glass fiber reinforced AES composite material has excellent overall performance, high strength, preferable rigidity, high-temperature resistance, preferable forming property and stable size; by adding the glass fiber, the heat deflection temperature of the composite material can be improved, the coefficient of linear expansion and the molding shrinkage of the material can be reduced, and therefore the application field of the AES material is expanded.

Description

[technical field] [0001] The invention relates to the field of polymer materials, in particular to a glass fiber reinforced AES composite material and a preparation method thereof. [Background technique] [0002] AES is a terpolymer of acrylonitrile, ethylene propylene diene monomer and styrene. Because of the synergistic performance of the three components, AES has excellent properties such as high surface hardness, good low temperature impact resistance, good weather resistance, good dimensional stability, small molding shrinkage, and excellent processing performance. [0003] At present, AES is mainly used in industries such as machinery manufacturing, automobile manufacturing, and electronic appliances that require high weather resistance. However, the mechanical properties, dimensional stability and thermal deformation temperature of AES cannot meet the requirements of engineering parts. Therefore, it must be modified to be suitable for some structural parts. [Conte...
