Problems solved by technology
However, the three-dimensional network structure of the emulsion prepared by this method has a low degree of crosslinking, insufficient water resistance, and insufficient protection for the surface of the substrate, which affects its anti-corrosion performance, and cannot deal with anti-corrosion caused by coating defects or coating damage. Persistence decreases, so it needs further improvement in practical applications

Abstract
The invention discloses antibacterial and mouldproof epoxy-acrylic acid anti-corrosion waterborne paint for indoor copper sculptures. The waterborne paint is prepared from, by weight, 40-60 parts of epoxy resin E-44, 0.1-0.15 part of 2-methyl-4-isothiazoline-3-ketone, 10-15 parts of ethylene glycol butyl ether, 15-25 parts of n-butyl alcohol, 0.1-0.15 part of glycerol monolaurate, 6-8 parts of methacrylic acid, 4-6 parts of styrene, 3-5 parts of butyl acrylate, 0.5-1 part of benzoyl peroxide, 4-6 parts of N,N-diformyl ethanol, 3-5 parts of titanium dioxide nanotubes, 0.3-0.5 part of nanosilver, 0.3-0.5 part of 1,2-aminoazophenylene, 0.1-0.15 part of gamma-mercaptopropyltriethoxysilane, 0.1-0.2 part of carboxymethyl chitosan and 100-120 parts of water. The waterborne paint for the copper sculptures has the excellent anti-corrosion property, mechanical property and lasting effectiveness and the antibacterial and mouldproof effects and is good in sanitary property.
Description
technical field [0001] The invention relates to the technical field of coatings for copper sculptures, in particular to an antibacterial and mildew-resistant epoxy-acrylic anticorrosive water-based paint for indoor copper sculptures and a preparation method thereof. Background technique [0002] With the improvement of modern living standards and aesthetic awareness, sculpture, a traditional handicraft, is loved by more and more designers and the public. Among them, copper sculpture is not only unique in style, but also has high appreciation value. Compared with sculptures made of other materials, it is also durable and not easy to damage, and has been widely used. Copper sculptures do not require frequent maintenance and repairs, but using them under conditions of excessive air humidity will seriously affect the quality of copper sculptures. In order to reduce corrosion and prolong the service life of copper sculptures, preventive measures are usually taken to protect the ...
