Embodiment 1

[0034] step 1:

[0035] First, mix the raw materials of each layer of the board above evenly in their respective mixing hoppers, and at the same time, carry out drying treatment at 80°C for 5 hours, and set the temperature of one of the extruders in the range of 200-250°C. The mixture of 96.9% PMMA, 3% titanium dioxide color masterbatch, and 0.1% benzotriazole UV absorber is melted and plasticized and then extruded to the distributor as the second layer of the plate, and the second extruder The temperature of the fuselage is set at 200-260°C. The mixture of 64% ABS, 30% PMMA and 6% titanium dioxide masterbatch is melted and plasticized, and then extruded into the distributor as the third layer of the board. The temperature of the body of the third extruder is set at 200-250°C, and the mixture of 0.2% benzotriazole UV absorber and 99.8% PMMA is melted and plasticized and extruded to the distributor as a plate fourth floor;

Abstract

The invention discloses an extruded acryl composite foam board and a preparation method thereof. The extruded acryl composite foam board comprises polymethyl methacrylate, a titanium dioxide color master batch, a benzotriazole ultra-violet absorber and an acrylonitrile-polystyrene copolymer. The raw materials are dried firstly, and then the extruded acryl composite foam board is produced by special four-layer co-extrusion and secondary compound methods. The invention has the advantages that the thickness of the prepared acryl composite foam board can be controlled within the range of 0.8-10 mm; the acryl composite foam board is more widely applied; and in performance, acryl composite layers have better homogeneity and cohesiveness. Because an arabesquitic, colored and uvioresistant PMMA layer is adopted as a second layer, the color of a product can be kept stable throughout the year, and the product has the function of ultraviolet resistance.

Description

technical field [0001] The invention relates to an extruded acrylic composite pearl board and a preparation method thereof, in particular to a preparation method of co-extrusion and secondary compounding, which is suitable for preparing extruded acrylic composite pearl boards for sanitary ware and decorative materials Methods. Background technique [0002] Acrylic composite pearl board is widely used in the fields of decorative materials, craft products and various sanitary ware because of its pearl-like noble and elegant luster, light weight, and easy processing, and is deeply loved and welcomed by people. But the variety of traditional acrylic composite pearl board is very single, and the surface hardness and smoothness are not high enough. It is generally made by secondary casting method. Due to the complicated process and low production efficiency of this production method, it cannot form batches and specialization. production. Secondly, the brittleness of the product ...
