Abstract

The invention discloses a silver-plated mirror and a preparation method thereof. The silver-plated mirror comprises a transparent substrate photochromic base material, wherein a nanometer anti-reflecting layer is formed by etching of the upper surface of the transparent substrate photochromic base material, a silver mirror layer is formed by chemical silvering of the lower surface of the transparent substrate photochromic base material, and a paint coating coats the silver mirror layer. When the silver-plated mirror prepared by the invention is used under strong light, the light incidence amount and the light reflection amount of the silver mirror layer are reduced, and the dazzling phenomenon is prevented; when the silver-plated mirror is used under dark light, the optical effect is closeto that of a common mirror, the Fresnel reflection is remarkably reduced, so that the viewing angle of the mirror surface is wider, and the influence of reflection shadow on optical performance is avoided. A preparation step of the nanometer anti-reflecting layer not only can prevent Fresnel reflection but also can properly coarsen the lower surface of the base material before the second silver plating, the adhesion of the silver mirror layer on the lower surface is improved, and the peeling phenomenon of a silver coating is prevented.

Description

technical field [0001] The invention relates to the technical field of silver mirror preparation, in particular to a silver-coated mirror and a preparation method thereof. Background technique [0002] The Fresnel reflection on the surface of the object often leads to the reduction of the optoelectronic performance of the device. In the optical system, the reflectivity of each layer of air-glass interface is nearly 4%, and the resulting "ghost image" leads to a decrease in image contrast. In the car dashboard It may even cause security problems. Therefore, it is of great significance to develop a surface anti-reflection structure with large-angle and wide-band characteristics. By forming an irregular nano-concave-convex structure with a characteristic size below 200nm on the surface of the object, it is equivalent to a layer of gradient refractive index interface, which can effectively reduce surface reflection. . [0003] Using nano metal particles (silver, gold, nickel, ...
