Abstract

The invention discloses a waterproof and antirust paint for metal. The raw materials are: water, silver paste powder, graphite powder, polyamide, tri-n-butylamine, wollastonite, potassium dichromate, ammonium molybdate, titanium dioxide and carbonic acid Calcium; used for anti-rust and anti-corrosion of medical appliances, the coating film has a smooth and bright appearance, and has a viscosity of 60-80s; first-class adhesion, no abnormality in salt spray resistance for 10-30d, water resistance for 20-60d without foaming or falling off; salt resistance The properties are 30-50d without abnormality, the surface dryness is 1-4h, and the actual dryness is 18-22h, the preparation method is simple, the raw materials are simple and easy to obtain, and it can be widely produced and continuously replace the existing materials.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a waterproof and antirust paint for metal. Background technique [0002] Coatings that protect metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea 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 bridges, ships, pipelines and other metals. ...
