Abstract

The invention discloses a weather-resistant matte PC / ASA alloy material, which comprises the following components in parts by weight: 69-75 parts of bisphenol A polycarbonate resin, acrylate rubber-acrylonitrile-styrene bonded Branch copolymer 14-20 parts, silicone toughening agent 3-7 parts, compatibilizer 2-4 parts, matting agent 4 parts, hindered phenolic antioxidant 0.2 part, auxiliary antioxidant 0.2 part, ultraviolet absorber 0.3 parts and lubricant 0.2 parts. The alloy material is made of bisphenol A polycarbonate, acrylic rubber, acrylonitrile and styrene graft copolymer as the main raw materials, supplemented by silicone compatible toughening, organic matting agent, high-efficiency antioxidant and special UV Absorbent and other components are combined, and the synergy of each component is used to achieve a matte matte effect on the surface of the material; the alloy material has the performance of weather resistance and high cold resistance, and has excellent physical properties, which can meet the requirements of outdoor weather resistance and can be widely used Used in automotive interior and exterior decoration, office equipment, communication equipment and outdoor lighting components.

Description

technical field [0001] The invention relates to an alloy material, in particular to a weather-resistant matte PC / ASA alloy material. Background technique [0002] Alloy materials are widely used. When used in interior and exterior decoration of automobiles, indoor office and outdoor electronic equipment, in order to avoid visual fatigue caused by people's long-term contact, the parts must have a matting effect. The traditional matting plastic products rely on "sandblasting" on the surface of the injection mold to achieve the matting effect. This method has the following disadvantages: first, the gloss of the plastic itself cannot be effectively reduced by external matting, and second, the mold needs to be frequently cleaned processing, increasing maintenance costs. [0003] Traditional PC alloy material matting technology, for example: PC / ABS alloy mainly uses bisphenol A type PC and matte grade ABS275 (Huajin Chemical) to add inorganic silica filling, inorganic matting age...
