Abstract

The invention discloses an amorphous alloy reflection mirror and a preparing method thereof. The reflection mirror comprises a base plate, a Zr-Ti-Cu-Ni-Al-Ag-Re amorphous coating with which the baseplate is coated, and a transition layer arranged between the base plate and the amorphous coating. The preparing method of the amorphous alloy reflection mirror mainly comprises the steps that firstly, Ti or Ni or Cr or Al serves as a target material, and the transition layer is prepared on the base plate; and secondly, the coating material serves as a target material, and an amorphous alloy reflection coating is sputtered to the transition layer. The disclosed reflection coating material has high reflectivity and is high in hardness, resistant to abrasion, resistant to corrosion, resistant tooxidization and resistant to vulcanization, the reflection coating material is used for manufacturing the reflection mirror, a protection layer is not needed for the surface, the manufacturing cost is lower than that of a pure silver and silver alloy reflection mirror, and the amorphous alloy reflection mirror is suitable for various occasions and particularly suitable for being used in the desert, high and cold and other severe environments.

Description

technical field [0001] The invention relates to the technical field of reflective coating materials, in particular to an amorphous alloy reflective mirror and a preparation method thereof. Background technique [0002] Utilizing the high reflectivity of silver, silver mirrors can be manufactured by vacuum coating or chemical reduction reaction. Although the silver reflective mirror has a high reflectivity, the silver reflective layer is expensive, has low hardness, and is not strong in oxidation resistance, vulcanization and corrosion resistance. It is an effective way to improve the physical and chemical properties of the silver layer by coating a protective layer on the surface of the silver reflective layer, such as the polyurethane protective layer used in Chinese patent CN102419459B and the SiOx protective layer used in Chinese patent CN101776778B. Contents of the invention [0003] The invention provides an amorphous reflective coating material, which is used to rep...
