Abstract

The invention discloses a single-component primer-topcoat paint commonly used on stainless steel, a galvanized sheet and an aluminum alloy, and a preparation method for the single-component primer-topcoat paint commonly used on the stainless steel, the galvanized sheet and the aluminum alloy. The single-component primer-topcoat paint commonly used on the stainless steel, the galvanized sheet and the aluminum alloy is prepared from the following components: epoxy modified acrylate resin, dimethylbenzene, butyl acetate, a flatting agent, a defoaming agent, an adhesion promoter, chlorinated paraffin, precipitated barium sulfate, rutile type titanium dioxide, carbon black powder, medium chrome yellow powder and polyamide wax. The paint prepared by the preparation method disclosed by the invention can meet the needs of a stainless steel substrate, a galvanized sheet bottom substrate and an aluminum alloy substrate, and really achieves multiple purposes. Meanwhile, the prepared paint is convenient to construct, stable in performance and great in quantity demand. As primer, the single-component primer-topcoat paint is excellent in adhesion with the three substrates, can be coated with polyurethane acrylate finish, fluorocarbon finish, and the like, and is good in covering power while being used as finish, and excellent in weather resistance.

Description

Technical field: [0001] The invention belongs to the technical field of coating chemicals, and in particular relates to a single-component, bottom-surface-in-one coating that can be used on stainless steel, galvanized sheets, and aluminum alloy surfaces and a preparation method thereof. The coating method can be spray coating or roller coating. technical background: [0002] For a long time, due to the different surface energies of the metal surfaces of stainless steel, galvanized sheets and aluminum alloys, the adhesion of paint on their surfaces is relatively poor, and corresponding paints should be made according to their different situations. In order to meet the performance requirements of adhesion, hardness, flexibility and impact at the same time. The one-component coating does not require a curing agent during construction, and has the advantages of fast drying speed, convenient construction, and high coating efficiency. But if you want to use a one-component bottom...
