Abstract

The invention discloses an ABS plastic with high impact resistance. The ABS plastic comprises the following components, by weight: 70-120 parts of ABS resin, 0.1-2 parts of a heat-conducting filler, 2-4 parts of an antioxidant, 5-10 parts of a silane coupling agent, 5-15 parts of a flame retardant, 0.3-1 part of an anti-ultraviolet agent, 1-4 parts of an initiator and 5-10 parts of modified nanocellulose. According to the invention, the auxiliary agent is added to modify the nano cellulose, and due to high strength, high modulus, good matrix compatibility and special effects of the nano cellulose, the impact resistance of the ABS plastic can be effectively improved when the nano cellulose is used as a reinforcing agent; and the ABS plastic is very suitable for manufacturing shells of household appliances.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to an ABS plastic with high impact resistance and high heat dissipation performance. Background technique [0002] ABS plastic is a terpolymer of acrylonitrile, butadiene and styrene. The addition of acrylonitrile provides ABS with high hardness and strength, heat resistance and corrosion resistance; butadiene gives ABS high impact resistance , toughness, cold resistance and certain ductility; while styrene ensures the good surface gloss, easy coloring and processability of ABS. ABS plastic is currently one of the most widely used thermoplastic engineering plastics with the largest production volume. ABS plastic is widely used in the manufacture of casings for household appliances, such as televisions, refrigerators, and computers. [0003] Home appliances may encounter certain impacts during transportation and use. ABS plastic is used as the housing of home appliance...
