High-performance PVC pipe for drainage and preparation method thereof

Abstract

The invention provides a high-performance PVC pipe for drainage. The high-performance PVC pipe comprises the following raw materials in parts by weight: 100 parts of a PVC main material; 0.5-4 part oftitanium dioxide; 0.4-1.3 parts of organic tin; 0.2-1.4 parts of an internal lubricant KG-16; 0.1-0.9 part of PE wax; 0.02-0.17 part of oxidized polyethylene wax; 0.03-0.4 part of glyceryl monostearate (GMS); 0.04-0.45 part of calcium stearate; 0.5-6.4 part of an MBS impact modifier; 1-18 parts of calcium carbonate; and 0.6-3.7 part of a green master batch. The PVC pipe structurally comprises a flaring, wherein a rubber ring is fixed at the flaring, and when the pipe is flared, the rubber ring and the pipe are integrally formed. The invention further provides a preparation method of the high-performance PVC pipe for drainage. According to the pipe produced by applying the pipe formula provided by the invention, the toughness and weather resistance are improved, and the pressure bearing capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of pipes, in particular to a high-performance PVC pipe for drainage and a preparation method thereof. Background technique [0002] In recent years, there has been an upsurge of investing in the construction of sewage pipeline systems in various parts of our country. Judging from the current situation in our country, China is a country with a serious shortage of water resources. Very limited water resources have been seriously polluted, causing a water crisis that hinders economic growth and social development. [0003] In order to solve the serious water crisis problem in our country, it is an effective and feasible way to improve the efficiency of sewage treatment. Therefore, there will be a strong market demand for buried sewage pipes. In addition, rainwater is a precious resource, and there is also a broad market for rainwater pipes that transport rainwater. The rainfall in many areas of China is conc...

AI Technical Summary

Problems solved by technology

[0005] 1. The quality of the existing PVC drainage pipes cannot meet the requirements of long-term use, and they are brittle, fragile and not durable;

[0006] 2. The pressure bearing capacity is poor, and when the drainage pressure is high, the water will not drain out or the pipe will rupture due to the high drainage pressure;

[0007] 3. Most of the existing pipe connection methods are glued, and the pipes and drainage pipes are bonded with glue; the joints are prone to failure, and it is difficult to guarantee the application performance
