Abstract

The invention relates to a low temperature resistant and weather-proof ASA (acrylonitrile styrene acrylate copolymer) material and a preparation method thereof. The ASA material comprises the following components: acrylate rubber, SAN (styrene-acrylonitrile copolymer) resin, a low temperature resistant modifier, PC (polycarbonate) resin, a UV (ultraviolet) absorbent, a UV stabilizer and antioxidants. The low-temperature impact resistance of the ASA material is obviously improved; the preparation process is simple, is low in cost, has high efficiency and has good application prospect.

Description

technical field [0001] The invention belongs to the field of ASA materials, in particular to a low-temperature and weather-resistant ASA material and a preparation method thereof. Background technique [0002] Acrylonitrile-styrene-acrylate terpolymerization (hereinafter referred to as ASA) material is one of the schemes to replace ABS material and improve weather resistance (the main molecular chain has no double bond weak point). Like ABS materials, ASA materials have the advantages of excellent mechanical properties, convenient processing and molding, recyclable scraps and less investment in equipment, etc., and are widely used in construction, automobile industry, outdoor sporting goods and other fields. As a paint-free material to replace ABS for outdoor use, it has become increasingly mature. [0003] The key technology for preparing low-temperature and weather-resistant ASA materials lies in the blending and dispersion of rubber content, low-temperature-resistant mod...
