Abstract

The invention discloses a high-impact resistance and high-brightness acrylonitrile-styrene-acrylate copolymer (ASA) alloy material and a preparation method thereof. The preparation method is characterized in that main raw materials of 30 to 90 parts of ASA, 0 to 50 parts of polycarbonate (PC) and 0 to 20 parts of polymethyl methacrylate (PMMA) is added with a dispersant, a lubricant, an anti-oxidant, a ultraviolet ray absorber and color pigment, and the mixture is subjected to mixing extrusion in a double-screw extruder to form the ASA alloy material. The ASA alloy material retains excellent ultraviolet ray resistance, excellent weatherability, high rigid, good chemical stability, good stainability and good chemical resistance of ASA resin, has high toughness, high brightness, excellent comprehensive properties, a low cost, good co-extrusion compatibility with polyvinyl chloride (PVC) and stable co-extruded layer thickness, does not produce distortion, layering and warping under a large temperature difference condition, can be utilized for preparation of uniform and stable profiles having different colors, and can be widely utilized for the building fields of plastic doors and windows.

Description

technical field [0001] The invention discloses a high-impact, high-brightness ASA alloy material and a preparation method thereof. Specifically, it relates to a high-impact, high-brightness ASA alloy co-extrusion material that can be used in construction fields such as plastic-steel door and window profiles or plastic-steel tiles, and a preparation method thereof. technical background [0002] With the development of social economy and the continuous improvement of people's living standards, the optimization of living environment and the beautification of urban buildings have become a beautiful landscape of modern cities. The single-color white PVC plastic profile can no longer adapt to the diversification of building wall decoration. The requirements of colored profiles and plastic doors and windows are gaining more and more favor due to their bright color, rich tones, and beautiful appearance. They will become a hot spot for consumption of plastic doors and windows in the ...
