Abstract

The invention discloses a water-based primer-topcoat coating which comprises the following components in parts by weight: 40-60 parts of a phosphate adhesive, 15-25 parts of titanium dioxide, 10-15 parts of barium sulfate, 2-5 parts of aluminum oxide, 2-5 parts of magnesium oxide, 5-15 parts of silica sol, 0.1-0.5 part of graphene oxide, 0.1-0.5 part of a thickening agent, 0.1-0.5 part of a surfactant and 30-50 parts of distilled water, by adding the silica sol, the graphene oxide and the aluminum oxide, improvement is achieved.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a water-based bottom surface integrated coating and a preparation method thereof. Background technique [0002] At present, the traditional anti-corrosion coating system is mainly two-side paint. The composite anti-corrosion coating system is composed of primer and top paint. The primer mainly plays the role of anti-corrosion and rust prevention, and the top paint mainly plays the role of anti-corrosion decoration. However, this kind of coating system has complicated process, long construction period, high cost, and it is easy to cause poor compatibility of the entire coating system, resulting in a decline in the performance of the entire coating. SUMMARY OF THE INVENTION [0003] The first object of the present invention is to provide a water-based bottom-surface-in-one coating, which has the advantages of smooth coating surface and high corrosion resistance. [0004] T...
