[0030] After blending the components according to the formula shown in Table 1 below, stir and mix them evenly in a high-speed mixer, then add them to the granulator together, and keep the temperature at 180°C-220°C for granulation to obtain anti-aging UV weather resistance ASA resin. After granulating and molding the UV and weather resistant ASA resin pellets, the properties of the UV and weather resistant ASA resin pellets were tested, as shown in Tables 1 and 2 below.

Abstract

The invention relates to an uvioresistant weather fastness ASA resin, a co-extrusion plastic product, a plastic thin film and a plastic product, wherein the uvioresistant weather fastness ASA resin comprises the following components according to weight percentage: 28%-96% of acrylonitrile-styrol copolymer, 3%-70% of polyacrylic core-shell copolymer, and 0.1%-5% of assistant. The uvioresistant weather fastness ASA resin is poly-blended with SAN through the polyacrylic core-shell copolymer (PBA-MMA), so that the weather fastness and low-temperature or room-temperature shock resistance of the ASA resin are remarkably improved, and the other physical properties of the ASA resin are not affected. The ASA resin has an excellent property of ultraviolet resistance as well as weather fastness, is easy to process, is further excellent in surface cleanness, keeps excellent rigidity, and is widely applied to various co-extrusion plastic products and thin films.

Description

technical field [0001] The invention relates to the technical field of polymer ASA resin, in particular to an ultraviolet-resistant and weather-resistant ASA resin, a co-extruded plastic product, a plastic film and a plastic product. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, polymer materials are more and more used in daily life, for example, various plastic products for life, auto parts, electrical casings and other fields. Especially for some plastic products that have been exposed to the outside for a long time, such as door and window profile products, on the one hand, they require a bright appearance, and on the other hand, they require high mechanical strength, impact resistance and weather resistance. [0003] SAN is acrylonitrile-styrene copolymer material is one of the most widely used plastics, acrylonitrile-styrene copolymer has high gloss, high transparency, high impac...
