Abstract

The invention discloses an aqueous antirust paint with rust. The antirust paint contains EVA (ethylene-vinyl acetate) emulsion, styrene-acrylate emulsion, pigment and filler, a dispersing agent, a film-forming aid, a penetrant, water and other components. The aqueous antirust paint with rust provided by the invention is convenient to construct, can be directly brushed without a rust removal process, has excellent rustproof, waterproof, anti-corrosion and other overall properties, and can be used for various metal surfaces with an antirust requirement.

Description

technical field [0001] The invention relates to a paint, in particular to a water-based anti-rust paint with rust. Background technique [0002] According to statistics, the direct economic loss caused by metal corrosion accounts for about 4% of the gross national product in my country every year. Therefore, the corrosion protection of metals has attracted more and more attention. In the previous metal anti-corrosion coating technology, the metal surface pretreatment before painting accounted for about 45% of the total price of the entire coating project. If the surface treatment processes such as rust removal, oil removal, and water removal can be reduced or omitted, the coating cost can be significantly reduced, and the painting process can be greatly simplified at the same time, thereby reducing labor intensity and reducing the harm of rust dust to the human body. At present, the solvent-based anti-rust paint with rust widely used in the industry is simple in constructi...
