Abstract

The invention relates to a water-based coating for a pipeline. The water-based coating for the pipeline comprises the following components: hydroxylated fiber resin, modified phenolic resin, asphalt, alkyd emulsion, carboxylic dibasic ester, isooctyl acrylate, man-made glass fiber, nano-powder, talcum powder, iron titanium powder, chromium oxide green, sodium hexametaphosphate, a methylalkylpolysiloxane solution, dodecyl mercaptan, a bactericide, a rust inhibitor, 1, 2-propylene glycol, additives and deionized water. The water-based coating for the pipeline has the following beneficial effects that the coating is good in adhesion, less prone to shedding and long in service life; furthermore, a preservative is added in the coating, so that the water-based coating can effectively prevent natural corrosion and microbial corrosion of the pipeline caused by iron bacteria.

Description

technical field [0001] The invention relates to a water-based paint for pipelines and relates to the field of paint preparation. Background technique [0002] Liquids or gases such as natural gas, oil, and tap water need to be transported by pipelines. During long-distance transportation, pipelines are generally buried underground. Due to the action of air, moisture and corrosive bacteria, the pipeline is prone to corrosion, causing the leakage of the transported fluid, resulting in serious consequences. Coating a layer of anti-corrosion paint on the surface of the pipeline is an effective means to protect the pipeline. Common pipeline coatings are generally solvent-based coatings, which seriously pollute the environment and consume organic matter that uses petroleum as raw materials during the production process. The application of water-based paint on pipelines as an environmentally friendly new paint is rarely seen so far. Contents of the invention [0003] The techn...
