Geothermal pipeline anti-scaling coating and preparation method thereof

The invention discloses an anti-scaling coating for geothermal pipelines. The anti-scaling coating comprises the following raw materials in parts by weight: 20-30 parts of epoxy resin E51, 3-6 parts of polyoxyethylene sorbitan fatty acid ester, 2-5 parts of a silane coupling agent KH560, 8-12 parts of a stability improver, 1-2 parts of an alicyclic amine curing agent, 4-7 parts of a wollastonite adjusting whisker agent and 25-30 parts of deionized water. According to the anti-scaling coating, the epoxy resin E51 is adopted and matched with the polyoxyethylene sorbitan fatty acid ester, the silane coupling agent KH560, the alicyclic amine curing agent and other raw materials, the stability improver and the wollastonite adjusting whisker agent are added for mutual blending and common synergistic effect, and the obtained product has the advantages of being anti-scaling, easy to clean and remarkable in acid corrosion resistance and water resistance stability effect. 本发明公开了一种地热管道防垢涂料，包括以下重量份原料：环氧树脂E51 20-30份、聚氧乙烯山
