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 epoxy-acrylic acid antiseptic waterborne varnish for a copper sculpture. The epoxy-acrylic acid antiseptic waterborne varnish is prepared from the following components in parts by weight: 40-60 parts of epoxy resin E-44, 3-5 parts of benzil dimethyl ketal, 5-10 parts of ethylene glycol monobutyl ether, 15-25 parts of n-butyl alcohol, 6-8 parts of methacrylic acid, 4-6 parts of styrene, 3-5 parts of isobornyl acrylate, 0.5-1 part of trimethylolpropane triacrylate, 1-2 parts of butyl acrylate, 0.5-1 part of benzoyl peroxide, 4-6 parts of N,N-dimethyl acyl ethanol, 3-5 parts of titanium dioxide nanotube, 0.3-0.5 part of benzene acrylic triazole, 0.1-0.15 part of gamma-mercaptopropyl triethoxy silane, 0.3-0.5 part of dimethyl silicone, 0.1-0.2 part of Tween-80, and 100-120 parts of water. The waterborne varnish for the copper sculpture has excellent anti-corrosion performance, mechanical performance and lasting effectiveness, and is good in fullness and excellent in appearance quality.
Description
Technical field [0001] The invention relates to the technical field of coatings for copper sculptures, in particular to an epoxy-acrylic acid anticorrosive waterborne bright paint for copper sculptures and a preparation method thereof. Background technique [0002] With the improvement of modern living standards and aesthetic awareness, sculpture, a traditional craft, is loved by more and more designers and the public. Among them, bronze sculptures are not only unique in style, but also have a high appreciation value. Compared with sculptures of other materials, they are also strong and durable, and are not easily damaged. They are especially widely used in modern urban landscape construction. Bronze sculptures do not require frequent maintenance and repairs, but they are used under conditions of excessive humidity, especially outdoor exposure to sunlight and rain, which will seriously affect the quality of bronze sculptures. In order to reduce corrosion and prolong the service ...
