Abstract

The invention relates to the field of organic coatings and discloses a quick-forming organic antiseptic protective film for the metal surface. The organic antiseptic protective film is formed by curing an organic antiseptic protective coating, the organic antiseptic protective coating is prepared from components in parts by mass as follows: 40-50 parts of an acrylic emulsion, 5-15 parts of inositol hexaphosphate, 5-15 parts of hydrated magnesium-aluminum silicate filler, 3-7 parts of iron oxide red, 3-7 parts of antibacterial particles, 2-4 parts of a compound tackifier, 3-7 parts of pigment, 0.5-1.5 parts of a dispersing agent, 0.5-1.5 parts of a defoaming agent, 3-7 parts of ethanol and 10-20 parts of water. The quick-forming organic antiseptic protective film has high binding force with the metal surface, no bubbles are generated after the film is formed, and the organic antiseptic protective film is corrosion resistance and ageing resistance and has an antibacterial property.

Description

technical field [0001] The invention relates to the field of organic coatings, in particular to a quick-formed organic anti-corrosion protective film on metal surfaces. Background technique [0002] Anti-rust coatings applied to metal surfaces, coatings that 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, 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 fo...
