Description

Technical field [0001] The invention relates to a PVC pipe, in particular to a modified PVC pipe with high toughness and high temperature resistance. Background technique [0002] The main component of PVC resin is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. In the synthesis process, PVC pipes require a variety of raw materials, and the cost is relatively high. Because PVC pipes have high stability, they are often used in water pipes and other pipelines that transport liquids. In use, a large number of fractures will occur due to external force extrusion. In the case of liquid leakage, the compressive strength and high temperature resistance of rigid PVC pipes currently on the market need to be improved. Summary of the invention [0003] In order to solve the technical problems existing in the background art, the present invention proposes a modified PVC pipe with high toughness and high temperature resistance, whi...
