Anticorrosive abrasion-resistant coating of pipe

Abstract

The invention relates to an anticorrosive abrasion-resistant coating of a pipe. The anticorrosive abrasion-resistant coating is prepared from the following components in parts by weight: 80 to 120 parts of organic silicon resin, 20 to 30 parts of polyurethane, 35 to 55 parts of carbon black, 45 to 52 parts of dispersing agent, 5 to 25 parts of dicyandiamide, 6 to 18 parts of ammonium polyphosphate, 10 to 15 parts of stabilizer, 0 to 8 parts of aluminium oxide, 5 to 12 parts of copper dioxide, 8 to 15 parts of glyceryl tristearate, and 43 to 60 parts of absolute ethyl alcohol. By using the coating, a pipe is difficult to scratch in an application process, and the service life of the pipe is prolonged.

Description

Technical field [0001] The invention relates to a coating, in particular to an anti-corrosion and wear-resistant coating of a pipe. Background technique [0002] Laying links often occupy an important position in the cost and energy consumption of plastic pipeline engineering. The basic method of trenchless laying technology is to use the trenchless method to lay the pipeline to the required underground line position. The most widely used trenchless technology for laying concrete pipes and steel pipes is the pipe jacking method. The most widely used method of trenchless technology is the horizontal directional drilling method. Because trenchless paving requires the plastic pipe to be pulled or pushed into the low hole drilled or the old pipe to be repaired, the surface of the pipe will inevitably be affected during this process. Damage, it is possible to directly contact sharp stones, etc., which will form a concentrated load in the pipe wall, which will damage the high stress c...

Problems solved by technology

The basis of trenchless laying technology is to lay the pipeline to the required underground line position by using the trenchless method. The most widely used trenchless technology for laying concrete pipes and steel pipes is the pipe jacking method. In the laying of plastic pipes The most widely used non-excavation technology is the horizontal directional drilling method, because the non-excavation laying needs to pull or push the plastic pipe into the hole drilled at the bottom or into the old pipe to be repaired. During this process, the surface of the pipe will inevitably be damaged. It is very likely that direct contact with sharp stones will form a concentrated load in the pipe wall, thereby damaging the high stress concentration and causing potential use risks. However, the wear resistance of ordinary polyethylene pipe coatings is not high, and the surface is easily worn
