Abstract

The invention discloses a weather-resisting matte PC / ASA alloy material. The weather-resisting matte PC / ASA alloy material is prepared from the following components in parts by weight: 69 to 75 partsof bisphenol A polycarbonate resin, 14 to 20 parts of acrylic rubber-acrylonitrile-styrene grafted copolymer, 3 to 7 parts of an organosilicone toughening agent, 2 to 4 parts of a compatilizer, 4 parts of a flatting agent, 0.2 part of a hindered phenol antioxidant, 0.2 part of an auxiliary antioxidant, 0.3 part of an ultraviolet absorbent and 0.2 part of a lubricant. The alloy material mainly takes the bisphenol A polycarbonate, an acrylic rubber body, acrylonitrile and a styrene grafted copolymer as main raw materials which are combined with the organosilicone toughening agent, an organic flatting agent, a high efficiency antioxidant, a special UV absorbent and other components, so that the matte fogging surface effect on the surface of the material is achieved by utilizing synergistic interaction of various components; the alloy material has the properties of weather resistance and high and cold resistance; meanwhile, the alloy material has excellent physical properties, can meet theoutdoor weather resistance requirements, and can be widely applied to automotive interior and exterior decoration, office equipment, communication equipment, outdoor lighting components and the like.

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...
