Description

technical field [0001] The invention relates to a fluorine silicon nanometer anti-corrosion engineering paint and a preparation method thereof. Background technique [0002] With the rapid development of modern industry, engineering anti-corrosion has attracted more and more attention from all aspects. The use of coatings is the most economical and effective method of anti-corrosion methods. In order to obtain excellent corrosion resistance, impurities such as rust on the substrate must be removed before painting. However, some large buildings, bridges, petrochemical, electric power, mining machinery and other complex equipment, oil and gas transmission pipelines, storage equipment, etc. have higher requirements for anti-corrosion paint. At present, engineering anti-corrosion paints have problems such as poor wear resistance, poor weather resistance, poor high temperature resistance, and short anti-corrosion period. Contents of the invention [0003] The technical probl...
