Abstract

The invention discloses enhanced modified ABS resin and a preparation method thereof. The enhanced modified ABS resin is prepared from the following components in parts by weight: 80-120 parts of ABSresin, 20-30 parts of acrylonitrile-styrene resin, 13-67 parts of glass fibers, 4.5-6 parts of glass beads, 6-8 parts of a styrene-maleic anhydride copolymer, 4.5-6 parts of maleic anhydride grafted polypropylene, 4.5-6 parts of high rubber content ABS and 1.1-1.4 parts of auxiliaries. The invention provides enhanced modified ABS resin and a preparation method thereof. According to the enhanced modified ABS resin, spherical glass beads and maleic anhydride grafted polypropylene are added, so that the problem that the enhanced ABS resin is locally whitened when being used for injection moldingof workpieces is solved, meanwhile, the modified ABS resin has excellent physical and mechanical properties, and the requirements of air conditioner fan blades on strength and thermal change performance are met.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a reinforced modified ABS resin and a preparation method thereof. Background technique [0002] Because of its high strength and hardness, excellent impact resistance and toughness, and heat resistance and corrosion resistance, ABS plastic has become one of the thermoplastic engineering plastics with the largest production volume and the most widely used. It is widely used in machinery, automobiles, and home appliances. manufacturing, etc. Among them, the axial flow fan blade of the outdoor unit of the air conditioner is a moving part, which is in a high temperature or low temperature environment for a long time. Therefore, the blade is required to have high tensile and bending strength, good heat resistance, and small linear expansion coefficient to ensure the stable performance of the whole machine. ABS plastic is widely used in the production of axial flow fan blade...
