Abstract

The invention provides a multifunctional ABS composite material, which is characterized being composed of the following components in parts by weight: 60 to 90 parts of ABS resin, 10 parts of ABS-g-MAH, 5 to 10 parts of alkali-free chopped glass fiber, 0.5 to 1.0 part of ferroferric oxide, 2 to 3 parts of composite carbon black, 0.5 to 0.8 part of lubricant, 5 to 10 parts of phosphorus flame retardant, 5 to 10 parts of nitrogen flame retardant, 0.5 to 1.0 part of silicon synergist, 2 to 3 parts of antistatic agent, and 0.5 to 1.0 part of antioxidant 1010. The phosphorus flame retardant and nitrogen flame retardant or the phosphorus flame retardant and silicon synergist are used together to generate a synergetic effect so as to improve the flame retardant efficiency, moreover, the toxic gas released during the burning process is reduced, and the provided ABS composite material has the advantages of low smoke and toxicity. Furthermore, the ABS composite material has a good mechanical property and a good electromagnet shielding performance, and has the advantages of rapid heat radiation, high electromagnet shielding efficiency, long-lasting antistatic effect, high mechanical strength, and easiness for flow processing. The application range of the ABS composite material is enlarged.

Description

technical field [0001] The invention belongs to the field of composite material processing, and in particular relates to a multi-performance ABS composite material. Background technique [0002] ABS resin is a blend of acrylonitrile-butadiene-styrene copolymer or acrylonitrile / styrene copolymer and styrene / butadiene copolymer, which is a graft copolymer of butadiene and acrylonitrile - Mixtures of styrene copolymers comprising 15%-35% acrylonitrile, 5%-30% butadiene and 40-60% styrene. As the ratio of the three components changes, the physical and mechanical properties of the ABS resin change accordingly. ABS resin is a thermoplastic polymer material with high strength, good toughness, heat resistance, low temperature resistance, chemical corrosion resistance, excellent mechanical strength and electrical properties, and easy processing and molding. ABS is widely used in automobiles, electronic appliances, building materials, packaging, sporting goods, machinery and instru...
