Abstract

The invention discloses a waterborne waterproof anticorrosive and antirust coating for metal. The waterborne waterproof anticorrosive and antirust coating is prepared from the following raw materials: deionized water, phosphoric acid, acetone, talcum powder, lac, butanol, zinc chrome, ethanol, zinc dihydrogen phosphate and butyl acrylate. The impact strength of a coating film is 5 to 25MPa; the coating film is flat and bright in appearance, and the viscosity is 55 to 75s; an adhesive force is a first grade, and salt-fog resistance can be lasted for 15 to 35 days without abnormality; water resistance can be lasted for 10 to 50 days, no discoloration and foaming occur, surface dryness needs 10 to 30 minutes, and hard dryness needs 1 to 5 hours. A preparation method is simple; raw materials are simple and easy to obtain; the waterborne waterproof anticorrosive and antirust coating can be widely produced and be used for continuously replacing an existing material.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a water-based waterproof, anti-corrosion and anti-rust paint for metal. Background technique [0002] Coatings that protect metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea deionized water, etc. Coating anti-rust coatings on the metal surface can effectively prevent the direct invasion of various corrosive substances in the atmosphere, so as to maximize the extension of the service life of the metal. It can be divided into two categories: physical and chemical antirust paint. The former relies on the proper coordination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical antirust effect of antirust pigments, such as red Dan, zinc yellow antirust paint, etc. Used for rust prevention of bridg...
