Abstract
The invention discloses a paint for pipelines, and belongs to the technical field of chemical industry paints. The paint comprises the following components in parts by weight: 15-25 parts of modified asphalt liquid, 2-5 parts of molybdenum disulfide, 0.5-1.3 parts of sodium pyrophosphate, 0.2-1.4 parts of N,N-dimethyl pyrrolidinone, 0.2-1.5 parts of anhydride maleique, 1-3 parts of polybutadiene epoxy resin, 0.3-1.5 parts of a dual-imidazoline quaternary ammonium salt corrosion inhibitor, 0.5-1.8 parts of ammonium persulfate, 2-3 parts of calcium metaaluminate and 2-6 parts of maleic acid. The paint has a good bacterial inhibition property, besides, a coating uniformly and effectively prevents the electrochemical reaction, and further the service life of the paint is prolonged.
Description
technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a coating for pipelines. Background technique [0002] When pipelines are used to transport fluids such as natural gas, coal, and oil, the pipelines are generally buried underground. However, due to soil corrosion, oil, gas, and water seepage, resulting in losses or accidents. Therefore, it is of great significance to study soil corrosion. . Soil corrosion is the corrosion of metals in soil. Soil is a special solid electrolyte with capillary porosity. The cathodic process of soil corrosion is mainly oxygen depolarization. Since oxygen reaches the cathode through the solid microporous electrolyte, the process is complicated and slow, and the structure and humidity of the soil have a great influence on the flow of oxygen. , the main corrosion factors are soil conductivity, air permeability (porosity), salt content, bacteria in the soil, and stray current. At present, t...
