Problems solved by technology

[0002] Today's domestic two-color co-extrusion materials are all made of imported ASA and PMMA base materials, and then added processing aids, antioxidants, ultraviolet absorbers, pigments, etc. It is extruded and granulated with ASA and PMMA as base materials, but the additives added are unknown. Compared with imported materials, the performance of domestic materials is very different. The processing technology of imported materials is unknown. Imported materials are used for two-color co-extrusion. Fast speed, good surface gloss, bright color, no shrinkage deformation, no chipping, and domestic materials are not good at all, only some small factories use them, imported materials are expensive, and there is little choice

Embodiment 1

[0012] Embodiment 1: A two-color co-extruded polymer alloy material is made of the following raw materials in parts by weight: acrylate rubber grafted styrene-methacrylate-N-phenylmaleimide copolymer resin 100 2-5 parts of plasticizer, 3-5 parts of antioxidant, 2.5 parts of lubricant, 0.1-1 part of ultraviolet absorber, 0.5-2 parts of pigment.

[0013] A preparation process for a two-color co-extruded polymer alloy material according to claim 1 comprises the steps of:

[0014] a) Add 100 parts by weight of acrylate rubber grafted styrene-methacrylate-N-phenylmaleimide copolymer resin into a high-mixer and mix for 3 to 5 minutes. When the temperature rises to 40°C Add plasticizer at ~60°C, add antioxidant when the temperature rises to 60°C-80°C after mixing for 5-7 minutes, add ultraviolet absorber when the temperature rises to 80°C-100°C after mixing for 3-5 minutes, Lubricant, continue mixing for 5-7 minutes, then add pigment, mix for 3-5 minutes, then cool and discharge;

Abstract

The present invention relates to a double color co-extrusion polymer alloy material and a preparation process thereof. The double color co-extrusion polymer alloy material is prepared from the following raw materials, by weight: 100 parts of an acrylate rubber grafted styrene-methacrylate-N-phenylmaleimide copolymer resin, 2-5 parts of a plasticizer, 3-5 parts of an antioxidant, 2.5 parts of a lubricant, 0.1-1 part of an ultraviolet absorber, and 0.5-2 parts of a pigment. According to the present invention, the acrylate rubber grafted styrene-methacrylate-N-phenylmaleimide copolymer resin is selected as the base material, and a plurality of auxiliary agents, the rational formula scheme and the rational preparation process are matched to produce the plastic alloy so as to replace the imported product, such that the cost is reduced, weathering resistance and aging resistance of the plastic alloy are better than weathering resistance and aging resistance of the imported product, and applicability is good, wherein the quality and the appearance of the plastic alloy achieve the similar foreign products, and the plastic alloy is suitable for double color double extrusion.
