Abstract

The invention relates to pipeline anticorrosive paint. The pipeline anticorrosive paint is prepared from, by weight, 29% of epoxy resin, 18% of polyurethane, 26% of coal tar, 9% of pigments, 3% of a regulator, 2% of a curing agent, 2% of a defoamer, 4% of a flame retardant, 3% of an antibacterial agent and 4% of a reactive diluent. By the arrangement, the paint prepared is good in electrical insulation and cohesive property, resistant to cathode stripping, good in physical and mechanical properties, high in stability and good in anti-microbial performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a pipeline anticorrosion coating. Background technique [0002] Pipelines are means of transportation for transporting large amounts of energy such as oil and gas. With the development of oil fields, chemical industry and urban construction, the laying of underground pipelines in our country will increase at an astonishing scale and speed. Under the influence of factors such as environment and service conditions, underground pipelines are prone to corrosion. Once the pipeline is corroded, it will cause serious economic losses and potential safety hazards. Coating anticorrosion is one of the important means of pipeline anticorrosion, so anticorrosion coatings, especially heavy anticorrosion pipeline coatings, have great potential in pipeline engineering and have a broad market prospect. The most direct reflection of the construction quality of long-distance oil and gas pipelines is the q...
