Problems solved by technology

[0009] However, there are still many technical problems in the co-extrusion of ASA and PVC profiles used for building materials in China, including raw materials and process technology: because the thickness of the ASA extrusion layer is very thin, the melt is very easy to break during extrusion; color co-extrusion At the same time, the toner is easy to remain and accumulate at the corner of the mold, which will damage the flatness and smoothness of the extruded profile surface

Abstract

The invention relates to an acrylonitrile-acrylate-styrene resin composite and a preparation method thereof. The composite comprises the following components in parts by weight: 10-80 of styrene-acrylate resin, 20-70 of acrylonitrile-acrylate-styrene resin, 0.5-10 of inorganic filler and 0.5-8 of processing auxiliary agent; the preparation method comprises the following steps that: the raw materials are put in a high-speed mixer for premixing for 3-10min, the obtained premixed materials are melted and extruded by a double-screw extruder, then cooling and granulation are carried out to obtain the extrusion-grade acrylonitrile-acrylate-styrene resin composite. Compared with the prior art, the invention has reasonable preparation technique, solves the problems of cracking due to insufficient strength of melt and surface defect caused by residual metal color powder, and simultaneously has the functions of purifying air and sterilizing.

Description

technical field [0001] The invention relates to a polymer composition and a preparation method, in particular to an acrylonitrile-acrylate-styrene resin composition and a preparation method. Background technique [0002] The performance characteristics of acrylonitrile-acrylate-styrene resin (ASA) can be summarized as follows: [0003] (1) ASA is an amorphous terpolymer with a saturated main chain structure and does not contain double bonds, so it has a strong resistance to ultraviolet light. The carbonyl and nitrile groups in the macromolecular chain have strong UV resistance, while the benzene ring is a typical stable structure, which is difficult to undergo photochemical reactions. Therefore, ASA has strong UV resistance, stable color, and good weather resistance. [0004] (2) Due to the introduction of acrylate rubber into the ASA structure, the copolymer has excellent impact resistance, especially low temperature impact resistance. [0005] (3) Since the ASA structure...
