Abstract

The invention provides an environment-friendly glass fiber reinforced AS composite material. The environment-friendly glass fiber reinforced AS composite material comprises, by weight percentage, AS resin, glass fiber, compatilizer, jellyfish grain, coupling agent, antibacterial agent and adjuvant, wherein the jellyfish grain comprises, by weight percentage, polypropylene, mineral filler and water. Compared with the prior art, the environment-friendly glass fiber reinforced AS composite material and the preparation method have the advantages that (1) a silane coupling agent is added, so that the adhesive strength between the glass fiber and the resin is enhanced; (2) the flavor can be removed effectively, and the mechanical property of the composite material is not affected by the utilization of the jellyfish grain; and (3) the prepared glass fiber reinforced AS composite material has excellent antibacterial effect through the addition of the antibacterial agent and can be utilized as antibacterial materials to be used in car, refrigerator and television industries.

Description

technical field [0001] The invention belongs to the field of plastic modification, and in particular relates to an environment-friendly glass fiber reinforced AS composite material and a preparation method thereof. Background technique [0002] Acrylonitrile-styrene (AS) resin is a thermoplastic produced by copolymerization of two monomers, styrene (St) and acrylonitrile (AN). AS resin has excellent properties, excellent dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, good molding and mechanical processing, and is an important engineering plastic. [0003] Glass fiber reinforced plastics have the advantages of high specific strength, corrosion resistance, heat insulation, and small molding shrinkage. In addition, the use of glass fiber reinforcement can greatly improve the tensile properties of plastics. Adding glass fiber to AS resin can enhance the strength and thermal deformation resistance of AS resin, and can also reduce...
