Problems solved by technology

[0004] Although ASA has good weather resistance, it still needs to be improved in terms of UV aging resistance. Adding other materials with poor weather resistance will affect its weather resistance, so it is often necessary to further improve its weather resistance

Abstract

The invention relates to an antistatic ultraviolet-resistant ASA / PET alloy material and a preparation method thereof; the material is prepared from the following components by weight: 60-90 parts of acrylonitrile-styrene-acrylate copolymer (ASA), 10-30 parts of polyethylene terephthalate (PET), 1-5 parts of styrene-grafted maleic anhydride copolymer, 2-5 parts of ethylene-acrylate copolymer, 0.2-3 parts of antistatic agents, 0.3-1 part of lubricants, 0.2-2 parts of light stabilizers, and 0.2-1 part of antioxidants. The product is prepared by preparing the raw materials in proportion, premixing, performing extrusion by a double screw extruder, and performing granulation. Compared with the prior art, the alloy material of the invention has the advantages of excellent mechanical properties, weatherability, antistatic performance, ultraviolet resistance, reduced cost, suitability of industrial scale production and popularization application, and the like.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to an antistatic and anti-ultraviolet ASA / PET alloy material and a preparation method thereof. Background technique [0002] Acrylonitrile-styrene-acrylate copolymer (ASA) is an impact-modified resin formed by the ternary copolymerization of styrene, acrylonitrile and acrylate. The structure of ASA and ABS is similar, and both contain styrene and Acrylonitrile, which retains the good mechanical and physical properties of ABS as an engineering plastic. Because it does not contain double bond structure, its weather resistance is much higher than that of ABS. At the same time, ASA resin has high impact resistance and high mechanical strength. Performance, good heat resistance and excellent coloring, etc. Polyethylene terephthalate (PET for short) has good physical and mechanical properties, especially in a wide temperature range, and has excellent electrical insulation, heat r...
