Problems solved by technology

[0002] Most of the plastic pipes on the market are single-color or full-color PVC pipes. Although the single white plastic pipes are low in cost, they are poor in decoration, and the surface is prone to yellowing after a period of use; although the full-color PVC pipes are rich in color , strong decoration, but the cost is high, and after a period of use of ordinary colored PVC pipes, the surface gloss will decrease and the color will fade.

Abstract

The invention discloses a colorful co-extruded plastic pipeline. The pipeline comprises a PVC base material and an ASA resin modified layer, wherein the ASA resin modified layer is prepared from the following components in percentage by mass: 5-45 percent of polycarbonate, 8-20 percent of PMMA, 0.1-0.4 percent of lubricant, 0.2-1.2 percent of dispersant, 0.4-0.8 percent of antioxidant, 0.25-0.7 percent of ultraviolet absorbent, 2-8 percent of pigment, 6-8 percent of calcium carbonate, 0.3-0.8 percent of silicon dioxide, 3-6 percent of stabilizer and the balance of ASA resin. The invention further discloses a particular method for compounding the PVC base material and the ASA resin modified layer by means of co-extrusion molding. The color durability of the colorful co-extruded plastic pipeline is greatly improved, and the prepared pipeline has uniform wall thickness and excellent surface performance.

Description

technical field [0001] The invention belongs to the field of plastic profile molding, and relates to a co-extruded plastic pipe, in particular to a plastic pipe formed by a color co-extruded method. Background technique [0002] Most of the plastic pipes on the market are single-color or full-color PVC pipes. Although the single white plastic pipes are low in cost, they are poor in decoration, and the surface is prone to yellowing after a period of use; although the full-color PVC pipes are rich in color , strong decorative, but the cost is high, and ordinary colored PVC pipes are also prone to "fading" phenomenon that the surface gloss will decrease and the color will lighten after a period of use. [0003] Therefore, it is necessary to provide a color co-extruded plastic pipe with low cost and good weather resistance. Contents of the invention [0004] In view of this, the object of the present invention is to provide a colored co-extruded plastic pipe, which has the ad...
