Problems solved by technology

[0002] Most of the existing spectacle frames are of a single color, and some spectacle frames with color-changing function are only made by spraying temperature-sensitive color-changing powder or light-sensitive color-changing powder on the surface of the spectacle frame. The color presented is not bright enough, and the color change is not obvious enough, the aesthetics is low, and the temperature change is often very slow. If you go out, the temperature generally does not change a lot, and it is easy to fall in sweat and rain. resulting in a shorter service life
[0003] Because glasses are products that people carry with them, they are often irradiated by outdoor ultraviolet rays and exposed to oxygen and moisture in the air for a long time, which leads to aging of ordinary eyeglass frames, and loss of light, color, and hair loss over time. Darkness and other disadvantages, the surface color will turn yellow. For some light-colored spectacle frames, the yellowing is more obvious, which seriously affects the aesthetics of the glasses and limits daily use.

Abstract

The invention discloses an ultrathin photosensitive resin coating and a preparation method thereof, and relates to the technical field of coating materials. The preparation method comprises the following steps: firstly, modifying epoxy resin by utilizing 3-hydroxy-1-naphthylamine, 5-chloro-1, 3, 3-trimethyl-2-methylene indoline, 3-amino phthalate and silver chloride to form photosensitive resin, so that a coating can be changed along with the change of illumination; then, ion beam assisted spinning is utilized, a copper fiber film is formed on the surface of the spectacle frame, the copper fiber film serves as an electric field cathode, photosensitive resin is ionized and deposited on the spectacle frame through a high-voltage electric field, aluminum oxide and silicon dioxide films grow layer by layer through electrostatic field assisted spraying, and water and oxygen substances are effectively blocked. The ultrathin photosensitive resin coating prepared by the invention has the effects of photochromic and yellowing resistance.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to an ultra-thin photosensitive resin coating and a preparation method thereof. Background technique [0002] Most of the existing spectacle frames are of a single color, and some spectacle frames with a color-changing function are only made by spraying thermochromic powder or photochromic powder on the surface of the spectacle frame. The color presented is not bright enough, the color change is not obvious enough, the aesthetics is low, and the temperature change is often very slow. resulting in a shorter service life. [0003] Since glasses are products that people carry with them, they are often exposed to outdoor ultraviolet rays, and they are exposed to oxygen and moisture in the air for a long time, which causes the aging of ordinary glasses frames. Darkness and other disadvantages, the surface color will turn yellow, and for some light-colored glasses frames, the ...
