Abstract

The invention discloses a high-gloss and high-impact-resistance ASA/PMMA (Acrylonitrile Styrene Acrylate/Polymethyl Methacrylate) material for an automobile and a preparation method thereof. The high-gloss and high-impact-resistance ASA/PMMA material is prepared by the following steps: taking the following raw materials in parts by weight: 100 parts of ASA, 40 to 60 parts of PMMA, 2 to 8 parts ofmaleic anhydride, 3 to 8 parts of 2,4-dichlorobenzoyl peroxide and 10 to 20 parts of impact modifying agent MBS; mixing for 3 to 5min until the appearance is uniform; adding 5 to 12 parts of dicumyl peroxide, 0.5 to 2 parts of antioxidant and 0.5 to 3 parts of halogen-free and high-gloss grease black pigment; carrying out mixing treatment until the appearance is uniform; adding mixed materials into a hopper of a double-screw extruder and melting and extruding, wherein the double-screw extruder has first-region temperature of 170 to 190 DEG C, second-region temperature of 175 to 195 DEG C, thethird-region temperature of 180 to 200 DEG C, the fourth-region temperature of 185 to 200 DEG C and the machine head temperature of 200 to 220 DEG C, the staying time is 2 to 3min and the pressure is10 to 20Mpa; extruding and granulating. The high-gloss and high-impact-resistance ASA/PMMA material disclosed by the invention has the advantages of high gloss, high impact resistance and relatively high weather resistance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and specifically relates to an ASA / PMMA material for high-gloss and high-impact automobiles, and also relates to a preparation method of the ASA / PMMA material for high-gloss and high-impact automobiles. Background technique [0002] Acrylonitrile-acrylate-styrene terpolymer (ASA) is a new type of resin with improved weather resistance compared to ABS. Compared with ABS, because the butadiene component is replaced by acrylate, it is no longer It has an unsaturated structure, so it has excellent weather resistance, which is about 10 times higher than that of ABS. At the same time, its mechanical properties, processing properties, electrical insulation, and chemical resistance are similar to ABS. ASA products can be used outdoors directly. After being exposed to sunlight for 9-15 months, the impact strength and elongation hardly decrease, and the color hardly changes. It can be applied to some ap...
