Abstract

The invention provides a single liquid type metal antirust paint, which comprises the following components by weight: 35-42 parts of a styrene acrylic emulsion, 15-20 parts of filler, 3-6 parts of pigment, 2-5 parts of a flame retardant, 5-10 parts of a cosolvent, 2-4 parts of a film-forming assistant, 3-5 parts of a dispersion agent, 1-3 parts of an anti-scratch agent, 60-70 parts of deionized water, 10-15 parts of PFA, and 6-8 parts of copper sulfate. The invention also discloses a preparation method of the single liquid type metal antirust paint. The single liquid type metal antirust paint provided by the invention has good flex resistance and high glossiness, and also has very strong corrosion resistance.

Description

Technical field: [0001] The invention relates to a single-liquid metal antirust paint. Background technique: [0002] Metal antirust coatings are coatings that can protect metal surfaces from chemical or electrochemical corrosion of 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 and maximize the service life of the metal. According to the principle of antirust, it can be divided into two categories: physical and chemical antirust paints. 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, etc. Anti-rust paint, etc.; the latter relies on the chemical anti-rust effect of anti-rust pigments, such as red lead, zinc yellow anti-rust paint, etc., used for rust prevention of metals such as bridges, ships, and pipelines. ...
