ASA/PVC co-extrusion ultra-weather resisting colorful rainwater pipeline

Abstract

The invention discloses an ASA / PVC co-extrusion ultra-weather resisting colorful rainwater pipeline special for outdoor rainwater drainage. The traditional VPC rainwater pipelines are white, and are hard to be harmonized with the appearance of a building or be applied to western high altitude areas. The pipeline consists of an internal layer and an external layer, and is characterized in that the external layer is made of an ASA modified material, and comprises the following compositions: acrylonitrile, styrene, acrylic rubber terpolymer, complex pigment, chlorinated polyethylene, stearic acid, calcium stearate, nanometer calcium carbonate, compounded lubricant, titanium pigment, UV absorbent and antioxidizer; the internal layer is prepared by the following compositions: polyvinyl chloride, chlorinated polyethylene, calcium stearate, titanium pigment, organic stabilizer and PE wax. The external layer made of the ASA material has ultra-weather resistance and multiple colors to meet the requirement on the colorful pipeline in the market currently; and the internal layer greatly improves the toughness of the pipeline.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to an ASA / PVC co-extruded super weather-resistant rainwater pipeline specially used for outdoor rainwater discharge. Background technique [0002] PVC rainwater pipe is a traditional pipe, which has been widely used in the field of building rainwater drainage, but the market segmentation of PVC rainwater pipes is not enough, no matter whether it is high-end or low-end, there is no obvious difference, especially in the high-end field However, there is no new pipe that can replace the traditional PVC rainwater pipe. [0003] Now more and more high-end real estates attach great importance to the appearance, the exterior design of the building is very colorful, but the traditional PVC rainwater pipes are all white, which is difficult to coordinate with the appearance of the building, so the applicant keeps receiving requests for colored PVC Market Feedback for Storm Sewer Pipes. In addition, ...

[0002] PVC rainwater pipe is a traditional pipe, which has been widely used in the field of building rainwater drainage, but the market segmentation of PVC rainwater pipes is not enough, no matter whether it is high-end or low-end, there is no obvious difference, especially in the high-end field , there is no new pipe that can replace the traditional PVC rainwater pipe

[0003] Now more and more high-end real estates attach great importance to the appearance, the exterior design of the building is very colorful, but the traditional PVC rainwater pipes are all white, which is difficult to coordinate with the appearance of the building, so the applicant keeps receiving requests for colored PVC Market feedback on storm sewer pipes

In addition, compared with the internal drainage of rainwater, the external drainage pipes of rainwater are exposed to the sun all the year round, which puts forward higher requirements for weather resistance, especially in high-altitude areas in the west, where the sun’s ultraviolet radiation is very severe. If there is no high weather resistance , the appearance and performance of the pipe will affect the service life of the pipe
