Epoxy-acrylic acid antiseptic water paint for yttrium aluminium garnet modified copper sculpture and preparation method thereof

Abstract

The invention discloses an epoxy-acrylic acid antiseptic water paint for yttrium aluminium garnet modified copper sculpture. The epoxy-acrylic acid antiseptic water paint is prepared from, by weight, 40-60 parts of epoxy resin E-44, 2-4 parts of amino resin, 10-15 parts of ethylene glycol butyl ether, 15-25 parts of n-butyl alcohol, 6-8 parts of methacrylic acid, 4-6 parts of styrene, 2-4 parts of butyl acrylate, 1-2 parts of itaconic acid di-butyl ester, 0.5-1 part of benzoyl peroxide, 4-6 parts of N,N-dicarboxy ethyl alcohol, 0.5-1 part of nanometer cerium fluoride, 3-5 parts of titanium dioxide nanotubes, 2-4 parts of nanometer yttrium aluminum garnet powder, 0.3-0.5 part of 1,2-aminoazophenylene, 0.1-0.15 part of gamma-mercaptopropyl triethoxy silane, 3-5 parts of PTFE emulsion and 100-120 parts of water. The copper sculpture water paint has the good antiseptic performance, mechanical performance and long-acting effectiveness, high in hardness, good in glossiness and high in weather resistance.

Description

Technical field [0001] The invention relates to the technical field of coatings for copper sculptures, in particular to an epoxy-acrylic acid anticorrosive water-based paint for yttrium aluminum garnet modified 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 durable and not easy to destroy. 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 ...

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
