Abstract

The invention relates to a nanometer scaling-resistant and anticorrosion coating material used in gathering pipelines, which is utilized to prevent scaling and corrosion inside petroleum gathering pipelines and characterized in that: the coating material consists of 1 weight portion of an agent A and 0.1 to 0.3 weight portion of an agent B, wherein, the agent A comprises bisphenol A epoxy resin, n-butyl alcohol, xylene, dibasic ester, polyether modified polydimethylsiloxane, high molecular weight block copolymer containing pigment affinity group, defoaming polysiloxane, polyether oxosilane copolymer, polyacrylate, high molecular weight poly carboxylic acid and nanometer titanium dioxide containing amine derivative, nanometer silicon dioxide, sericite, talcum powder and crystalline flake graphite; and the agent B comprises polyamide additive product, n-butyl alcohol and dibasic ester. The effects of the invention are that: the coating material has good constructability and storage stability and the film coating thereof has excellent scaling-resistant performance and good anticorrosion performance; the rate of scaling prevention for the pipelines can achieve above 80 percent.

Description

technical field [0001] The invention relates to the technical field of pipeline anti-corrosion coatings, in particular to a nano-scale anti-scaling and anti-corrosion coating for oil gathering and transportation pipelines with excellent anti-scaling performance and corrosion resistance and a manufacturing method thereof. technical background [0002] As the oilfield development enters the middle and later stages, the water content in the produced fluid increases sharply. The high liquid volume, high salinity, high sand content, low pH value of the produced water, and the mixed operation of heterogeneous water production wells in different blocks lead to increasingly serious fouling of oilfield gathering and transportation pipelines, and the scaling and blockage of pipelines intensifies , greatly reducing the life of the gathering pipeline. Frequent cleaning and descaling and replacement of pipelines have destroyed the continuous production of oil wells, seriously affected t...
