Abstract

The invention discloses a single-component scale type epoxy zinc-rich anti-corrosive primer and a preparation method thereof, belongs to the field of industrial anti-corrosive coatings, and solves the problems of poor paint film flexibility, serious zinc powder precipitation and poor salt spray resistance of existing anti-corrosive coatings. The anti-corrosive primer comprises linseed oil modified epoxy resin, a dispersing agent, bentonite, fumed silica, flaky zinc powder, glass flakes, nano nickel-titanium alloy, superfine ferrophosphorus powder, a drier cobalt iso-octoate, an adhesion promoter, xylene and butyl acetate. The preparation method comprises the following steps: sequentially adding the linseed oil modified epoxy resin, the dispersing agent, the bentonite, the fumed silica, the flaky zinc powder, the glass flake, the nano nickel-titanium alloy and the superfine ferrophosphorus powder, and performing uniform stirring; increasing the rotating speed for high-speed dispersion; adding the drier cobalt iso-octoate, the adhesion promoter, the xylene and the butyl acetate while stirring; and performing filtering and packaging. The anti-corrosive primer is excellent in performance and convenient to prepare.

Description

technical field [0001] The invention belongs to the field of industrial anticorrosion coatings, and in particular relates to a single-component scale-type epoxy zinc-rich antirust primer and a preparation method thereof. Background technique [0002] The anticorrosion of coatings often requires primer, intermediate paint, topcoat or a paint system that cooperates with each other between primer and topcoat. The role of primer in the entire paint system is particularly important. The commonly used primers are: : Two-component epoxy zinc-rich primer, one-component epoxy antirust primer and hot-dip galvanized coating. The most widely used is epoxy zinc-rich primer. It not only has excellent anti-corrosion performance, but also has excellent adhesion, heat resistance and does not affect welding. It is a steel structure bridge, ship, dock, factory building, pipeline, etc. The main supporting primer in heavy anti-corrosion coatings such as steel towers and iron towers. Commonly u...
