Anticorrosive paint for concrete and manufacturing method thereof

The invention relates to an anticorrosive paint for concrete and a manufacturing method thereof. The anticorrosive paint for the concrete consists of a primer and a finishing coat, the primer consistsof amorphous silica, amorphous alumina, polymethyl acrylate, polyacrylamide, sodium dodecyl sulfonate, ammonium persulfate and deionized water, and the finishing coat consists of nano aluminum oxides, nano silicon oxides, isopropanol, fillers, methyltrimethoxysilane, polydimethylsiloxane, gamma-glycidyloxypropyl trimethoxysilane, acetic acid and the like. The manufacturing method of the anticorrosive paint for the concrete includes the steps of obtaining a dispersion A, obtaining a semi-finished product B, mixing the semi-finished product B with the dispersion A to obtain the primer, and stirring the components A and B after mixing to prepare the finishing coat. According to the technical scheme, inorganic polymer materials are adopted, harmful volatile organic substances are not generated, the paint itself is mo
