Anticorrosion pipeline coating material

Abstract

The present invention relates to an anticorrosion pipeline coating material, which comprises, by mass, 60-90 parts of polyurethane, 20-30 parts of toluene diisocyanate, 15-20 parts of trihydroxy polyether, 11-15 parts of quartz powder, 4-6 parts of zinc phosphate, 3-6 parts of talc powder, 5-10 parts of barium sulfate, 1-2 parts of castor oil, and 2-3 parts of zinc powder. According to the presentinvention, the anticorrosion pipeline coating material has the improved formula and has strong corrosion resistance; and after the pipeline is coated with the coating material prepared according to the formula, the anticorrosion effect can be maintained for ten years.

Description

technical field [0001] In particular, the invention relates to an anti-corrosion pipeline coating. Background technique [0002] In recent years, with the rapid development of my country's petrochemical industry and the improvement of the construction speed of urban public facilities, the construction of underground metal pipelines in my country is also developing rapidly. Since most of the underground pipelines are made of metal, they are easily corroded by factors such as soil and bacteria. Corrosion of underground pipelines will bring huge economic losses and social security to human beings and the social environment. Therefore, the construction of new pipelines and the maintenance of existing pipelines have put forward important tasks for anticorrosion engineering. Contents of the invention [0003] The present invention proposes a kind of anticorrosion pipe coating to above-mentioned problem. [0004] The specific technical scheme is as follows: [0005] A kind of ...
