Abstract

The invention provides an aqueous rusty brushing anti-corrosion paint for an electric transmission and transformation iron tower and a preparation method thereof; the formulation of the paint comprises liquid epoxide resin, aqueous epoxy hardener, rustproofing pigment, extender pigment and other paint additives, and deionized water is used as solvent; liquid epoxide resin includes bisphenol A-type liquid epoxide resin and I-type aqueous epoxy hardener, the rustproofing pigment includes aluminium trippolyhosphate, zinc phosphate and the like, and the extender pigment includes barium sulfate, talcum powder and titanium and the like; the anti-corrosion paint prepared by the invention can be used for anticorrosion of a rusted iron tower surface, slight treatment to the surface of the rusted iron tower is only needed, so as to remove surface bulk materials, grease and other bulk material, and then coating can be carried out; the coating can remarkably improve the corrosion resistance of steel products and has good salt fog resistance and weather resistance.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and relates to a water-based anti-corrosion paint for brushing with rust and a preparation method thereof. Background technique [0002] Rust is a porous, constantly producing (expanding) substance, and applying paint to its surface will reduce the corrosion protection of the paint film. Generally, before painting, it is necessary to carry out strict and complicated surface treatment procedures on the surface of the rusted steel, which is time-consuming and labor-intensive and increases the cost. The structure of the power transmission and transformation tower is complex. During the maintenance process, limited by the construction conditions, the rust layer is not thoroughly treated, and there are residual rust and various corrosion residues, which reduces the corrosion resistance of the paint film. Therefore, more and more attention is paid to the anti-corrosion of rust-bearing coa...
