Problems solved by technology

[0003] However, due to the disadvantages of PVC resin itself, such as poor thermal stability, poor low temperature resistance, poor fluidity and insufficient toughness, it is necessary to add various additives to improve its performance.
Therefore, domestic and foreign countries have successively developed high-impact PVC pipes, mainly using elastomers for toughening, and the most widely used is chlorinated polyethylene (CPE). This method can improve the toughness of PVC pipes, but the amount of CPE added Larger, due to the network toughening mechanism of CPE, the processing conditions are relatively harsh, and it is difficult to achieve a rigid-tough balance
Although this kind of pipe has been promoted to a certain extent, its impact resistance at low temperature (-10°C) is still poor. At the same time, the existing pipe has high density, short pressure resistance time, and high production cost.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, in particular to a high-rise laminated rainwater pipe and a manufacturing method thereof. Background technique [0002] In the water supply system, plastic pipes have the characteristics of non-corrosion, good hygienic performance, and easy installation. They have been vigorously promoted in my country, and it is the general trend to replace traditional galvanized iron pipes. Plastic water supply pipes mainly include: PVC, polyethylene (PE), polypropylene (PP), etc. Compared with other polyolefin pipes, PVC pipes have high strength, good flame retardant performance, high ring stiffness, and excellent weather resistance. The advantages of performance and lower price are widely used. [0003] However, due to the shortcomings of PVC resin itself, such as poor thermal stability, poor low temperature resistance, poor fluidity and insufficient toughness, various additives should be added to impr...
