Preparation method of friction-resistant drainage pipeline

Abstract

The invention discloses a preparation method of a friction-resistant drainage pipeline. A formula comprises the following raw materials in parts by weight, 80-90 parts of chlorinated polyethylene, 15-20 parts of fluororubber, 8-12 parts of nano silicon dioxide, 4-9 parts of nano silicon carbide, 6-8 parts of nano calcium carbonate, 3-5 parts of nano bamboo charcoal powder, 6-10 parts of glass fiber, 1-2 parts of titanate coupling agent, 2-3 parts of an antibacterial agent, 3-5 parts of a plasticizer, 1-3 parts of an antioxidant and 1-3 parts of a light stabilizer. Nano silicon dioxide, nano silicon carbide and nano calcium carbonate are used as mixed auxiliary materials for preparing the drainage pipeline, so that polymer material strength can be increased; the nano bamboo charcoal powderis added in drainage pipeline material preparation process, the nano bamboo charcoal powder and the antibacterial agent are combined to improve the antibacterial property of the pipeline material, thedrainage pipeline corrosion resistance is improved further, and drainage pipeline service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of drainage pipes, in particular to a preparation method of a friction-resistant drainage pipe. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. At present, the main plastic pipes include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, polypropylene PPR hot water pipes, e...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing drainage pipes exposed to the ground for a long time are prone to aging, deformation, cracking and other problems, and have the disadvantages of poor weather resistance, temperature resistance and mechanical impact resistance. When the drainage pipe is damaged, it will take time to repair and replace Laborious, increasing the use cost of drainage pipes;

[0005] 2. The existing drainage pipes have poor antibacterial properties, and bacteria are easy to breed inside during long-term use, which will cause certain pollution to the drained water flow under certain circumstances and affect the use of water sources;

[0006] 3. In the preparation process of existing drainage pipes, the paint is usually dried by natural air drying after spraying the inner wall of the pipe. This kind of paint drying method takes a long time and has low efficiency, which greatly reduces the production efficiency of the enterprise. At the same time By natural air drying, it is easy to cause uneven coating of the paint inside the pipe wall, which reduces the production quality of the drainage pipe
