Abstract

The invention discloses a highlight high-weather-resistance and heat-resistant ASA composite material, relating to the technical field of high polymer materials. A coextruded material contains the following raw materials in parts by weight: 25-35 parts of ASA rubber powder, 30-45 parts of AS resin, 30-40 parts of PMMA, 30-40 parts of an n-phenylmaleimide-styrene-maleic anhydride copolymer, 0.1-0.3 part of a ultraviolet absorber, 0.3-0.5 part of a light stabilizer, 0.3-0.8 part of an antioxidant, 0.5-1.5 parts of a brightener, 0.1-0.3 part of a demolding agent, 0.3-0.6 part of a dispersing agent and 1-3 parts of a toner. The invention further discloses a preparation method of the highlight high-weather-resistance and heat-resistant ASA composite material. The highlight high-weather-resistance and heat-resistant ASA composite material has excellent weather resistance, good heat resistance and high luster and is unlikely to fade.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss high-weather-resistant and heat-resistant ASA composite material and a preparation method thereof. Background technique [0002] ASA (English name: Acrylonitrile Styrene acrylate copolymer), engineering plastics, is a graft copolymer of acrylic rubber, acrylonitrile, and styrene, and the molding temperature is 170-230°C. [0003] Advantages of ASA: [0004] (1) ASA has good mechanical and physical properties; [0005] The structure of ASA and ABS is similar, and it retains the excellent mechanical and physical properties of ABS as an engineering plastic. [0006] (2) ASA has strong weather resistance; [0007] If the high molecular polymer contains double bonds, the double bonds are easily opened by the ultraviolet rays in the sunlight with high energy intensity, resulting in a decrease in the aging resistance of the high molecular polymer, and ASA is us...
