Problems solved by technology

[0003] As an anti-corrosion coating, it will be applied to metals in various fields and occasions, and it must adapt to various natural or artificial environments. For the existing anti-corrosion coatings, it can only be applied in some relatively mild places. Once in some harsh conditions In the environment, its life will be greatly shortened
[0004] The most important thing is that most of the existing metal anti-corrosion coatings contain some harmful substances such as benzene, toluene and xylene, and some coatings contain formaldehyde, which are relatively harmful to the environment and human body

Abstract

The invention discloses a weather-resistant environmentally-friendly water-based metal anticorrosive coating. The weather-resistant environmentally-friendly water-based metal anticorrosive coating comprises, by mass, 45 to 52 parts of a styrene-acrylic emulsion, 15 to 25 parts of an acrylic emulsion, 6 to 12 parts of silicone resin, 10 to 16 parts of polyurethane resin, 14 to 20 parts of a filler,1 to 3 parts of a dispersant, 2 to 5 parts of a thickener, 4 to 7 parts of a stabilizer, 2 to 5 parts of a drier, 0.5 to 3 parts of a filming aid and 80 to 100 parts of water. The weather-resistant environmentally-friendly water-based metal anticorrosive coating is water-based paint, is free of harmful odor and few substances, can recoat a used position, can be cleaned with clear water and soap,is not combined with dangerous and flammable solvents, is free of solvent remove after construction, can be fast dried and fast coat, has strong UV resistance, can be used in different environments and has good weather resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a weather-resistant and environment-friendly water-based metal anti-corrosion coating. Background technique [0002] Anti-corrosion technology For metal materials and their products in corrosive media, various anti-corrosion technologies are used to prolong the service life of metal products and ensure the safe and smooth operation of process equipment. [0003] As an anti-corrosion coating, it will be applied to metals in various fields and occasions, and it must adapt to various natural or artificial environments. For the existing anti-corrosion coatings, it can only be applied in some relatively mild places. Once in some harsh conditions environment, its lifespan will be greatly shortened. [0004] The most important thing is that most of the existing metal anti-corrosion coatings contain some harmful substances such as benzene, toluene and xylene, and some coatings contain ...
