Corrosion-resistant sewage drainage tube material and preparation method thereof

Abstract

The invention discloses a corrosion-resistant sewage drainage tube material and a preparation method thereof, and relates to the field of pipeline materials. The corrosion-resistant sewage drainage tube material is prepared from the following raw materials in parts by weight: 60-70 parts of polyvinyl chloride, 20-30 parts of acrylonitrile-butadiene-styrene copolymer, 20-30 parts of polyacrylate, 4-10 parts of dioctyl phthalate, 3-8 parts of dioctyl sebacate, 15-20 parts of heavy calcium carbonate, 8-16 parts of barium sulfate, 6-13 parts of red mud, 8-15 parts of modified glass fibers, 5-10 parts of glass micro beads, 3-8 parts of polyglutarylimide, 4-7 parts of nano titanium dioxide, 2-5 parts of magnesium stearate, 2-5 parts of calcium stearate and 2.5-5 parts of titanate coupling agent.The corrosion-resistant sewage drainage tube material is stable in physical and chemical property, has excellent corrosion resistance, wear resistance, temperature resistance and mechanical impact resistance, is resistant to corrosion of chemical substances in sewage, and is long in service life.

Description

Technical field [0001] The invention relates to the field of pipeline materials, in particular to a corrosion-resistant sewage drainage pipe material and a preparation method thereof. Background technique [0002] Like the development of my country's construction water supply and drainage profession, my country's water supply pipes have experienced a single variety and slow development in the past. Traditional drainage pipes mostly use non-galvanized steel pipes (black iron pipes) and galvanized steel pipes, which have now been eliminated in most places. In order to save steel, the reinforced concrete pipes popularized in the last century can withstand higher working pressure, are corrosion-resistant, low-priced, and durable. They will not reduce the drainage capacity of the water pipe, but they have a large weight, hard and brittle texture, and fear of collision. , The interface is easy to leak, difficult to install and difficult to maintain. Plastic pipes are now mostly used. ...

AI Technical Summary

Problems solved by technology

In order to save steel, reinforced concrete pipes popularized in the last century can withstand high working pressure, are corrosion-resistant, cheap, and durable, and will not reduce the drainage capacity of water pipes, but they have a large weight, hard and brittle texture, and are afraid of collisions. , the interface is easy to leak, difficult to install and maintain

Nowadays, plastic pipes are mostly used. Plastic pipes have good anti-corrosion and shock resistance, and have certain tensile and bending resistance elasticity, but they have the disadvantages of brittle texture, easy corrosion and aging.
