The invention relates to a preparation method of a
corrosion-resistant environment-friendly
coating. The preparation method comprises the following steps of: step 1, weighing the following raw materials in parts by weight: 55-75 parts of modified organic
silicon, 25-30 parts of an environment-friendly
emulsion, 8-15 parts of a nano filler, 1-3 parts of a
thickening agent, 0.5-1.5 parts of a stabilizer and 55-60 parts of absolute ethyl
alcohol; step 2, adding the modified organic
silicon, the environment-friendly
emulsion and the stabilizer into the absolute ethyl
alcohol to obtain a
mixed solution; and 3, adding the nano-filler into the
mixed solution prepared in the step 2, and performing dispersing for 30 minutes at the rotating speed of 160-180 r / min to obtain the
corrosion-resistant environment-friendly
coating. A second intermediate ismixed with dissolved methyl phenyl
silicone rubber under the action of tetraethoxysilane serving as a curing agent, and
dibutyltin dilaurate servingas a catalyst, and the methyl phenyl
silicone rubber is modified, and therefore, the technical problem of poor compatibility of a first intermediate and the methyl phenyl
silicone rubber is solved; and moreover, the prepared
coating has excellent
corrosion resistance.
