Problems solved by technology

For example, the Chinese patent application (publication number: CN105778355A) discloses a low-density impact-modified polyvinyl chloride pipe and its production process. It uses polyvinyl chloride resin as the matrix material and adds polymer hollow microspheres to improve the composite pipe. The toughness and low-temperature impact resistance of the material, however, the high-molecular hollow microspheres have high cost in the production and processing process, are not easy to process, and are not conducive to industrial production

Description

technical field [0001] The invention relates to a composite material used for a high-impact polyvinyl chloride reinforced pipe, which belongs to the technical field of polymer materials. Background technique [0002] Polyvinyl chloride is one of the five general-purpose plastics at present, and polyvinyl chloride pipes have become the most widely used pipe type due to their low cost, simple processing and convenient construction. [0003] Rigid polyvinyl chloride (PVC-U) reinforced pipe is a novel pipe with smooth inner wall and vertical reinforcing ribs on the outer wall produced by processing hard polyvinyl chloride as the main raw material. Its main performance is: strength and rigidity can withstand the load capacity under the geographical environment; hydraulic characteristics are suitable for the ability to transport liquid; no leakage, prevent environmental pollution, wear resistance, easy installation, and comprehensive economy. Mainly used for underground sewage an...
