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 high-flexibility anti-crack anticorrosion epoxy-acrylic acid water-based paint for copper sculptures. The water-based paint is prepared from, by weight, 40-60 parts of epoxy resin E-44, 3-5 parts of polyvinyl butyral, 10-15 parts of ethylene glycol butyl ether, 15-25 parts of n-butyl alcohol, 0.3-0.5 part of diacetyl tartaric acid ester of mono(di)glycerides, 6-8 parts of methylacrylic 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-dicarboxy ethanol, 0.1-0.15 part of sodium lignosulphonate, 3-5 parts of titanium dioxide nanotubes, 0.3-0.5 part of benzotriazole, 0.1-0.15 part of gamma-mercaptopropyltriethoxysilane, 0.3-0.5 part of hydroxypropyl guar gum and 100-120 parts of water. The water-based paint for the copper sculptures has advantages of excellent corrosion resistance, mechanical property and lasting effectiveness, high flexibility, excellent crack resistance and high durability.

Description

technical field [0001] The invention relates to the technical field of coatings for copper sculptures, in particular to an epoxy-acrylic anticorrosive water-based paint for highly flexible and crack-resistant 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. It is especially widely used in modern urban landscape construction. Copper sculptures do not require frequent maintenance and repairs, but use under conditions of excessive air humidity, especially outdoor sun and rain, will seriously affect the quality of copper sculptures. In order to reduce corrosion and prolong the service life of copper s...
