Embodiment 1

[0021] The present invention provides a kind of mirror back protection coating with anticorrosion, and by weight percentage, described coating comprises following raw material:

[0022]

[0023] The fluorine-containing acrylic resin is a polymer of perfluoroethylene and fluorine-containing acrylic monomer, wherein the fluorine-containing acrylic monomer is not less than 60% of the total weight of the monomers.

[0024] The modified acrylic resin is a polymer of trifluoropropylene oxide and fluorine-containing acrylic monomer, wherein the fluorine-containing acrylic monomer is not less than 60% of the total weight of the monomers.

[0025] The fluorine-containing acrylic monomer is one or more of trifluoroethyl acrylate and trifluoroethyl methacrylate, that is, the fluorine-containing acrylic monomer is trifluoroethyl acrylate, or trifluoroethyl methacrylate Ethyl ester, or a mixture of trifluoroethyl acrylate and trifluoroethyl methacrylate in any proportion.

[0026] The ...

Embodiment 2

[0033] On the basis of embodiment 1, present embodiment 2 is as a preferred embodiment of the present invention, and a kind of mirror back protection paint with anticorrosion, by weight percentage, comprises following raw material:

[0034]

[0035]

[0036] Wherein, the filler is prepared from aluminum tripolyphosphate, glass flakes, mica powder and wollastonite in a weight ratio of 12:10:7:6; , N-methylpyrrolidone and ethanol are prepared by mixing in a weight ratio of 20:21:22:29; the preparation method of the mirror back protective coating is the same as in Example 1.

Abstract

The invention discloses an anticorrosive mirror back protecting coating and a preparation method thereof, and relates to the field of mirror back protecting coatings. The coating comprises the following raw materials in percent by weight: 15-25% of fluorine-containing acrylic resin, 10-25% of modified acrylic resin, 0-15% of fillers, 2-15% of a pigment, 0-10% of an auxiliary agent and 15-45 % of asolvent. Through the use of the fluorine-containing acrylic resin and the modified acrylic resin as main film-forming substances, the anticorrosive mirror back protecting coating has a high film-forming speed, excellent corrosion resistance, acid and alkali resistance and water resistance, can be applied to shower coating, spray coating or roll coating, adopts a simple and easily operated coatingprocess, and has a good coating effect.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a mirror back protection coating with anti-corrosion properties and a preparation method thereof. Background technique [0002] Mirrors used in daily life, such as mirrors on furniture, mirrors hung in shops and living rooms, people always hope to use for a long time to keep the mirror surface bright and clear forever. However, if the mirror is used for a period of time, or even several months, some light green or black spots will appear on the surface, and in severe cases, the entire mirror surface will be blurred. [0003] Mirrors are divided into silver mirrors and aluminum mirrors, which are composed of three parts: flat glass, metal reflective layer (silver layer or aluminum layer) and mirror back paint. The mirror surface of the mirror becomes blurred, mainly because the hot and humid environment in the rainy season first destroys the mirror back coating and then damages the metal ...
