Abstract

The invention belongs to an anti-oxidation material, in particular to an anti-oxidation film and a preparation method, comprising the following components in parts by weight: 45-60 parts of silicon dioxide, 5-10 parts of boron oxide, and 5-10 parts of zinc oxide 15 parts, potassium oxide 20‑30 parts, the film is nano-scale, dense and transparent, uniform and continuous, and has anti-oxidation, high temperature resistance, and good weather resistance, which effectively solves the problem of easy oxidation and discoloration of carrier materials.

Description

technical field [0001] The invention belongs to an anti-oxidation material, and in particular relates to an anti-oxidation film and a preparation method. Background technique [0002] Sterling silver is a beautiful silvery-white metal with attractive metallic luster and collection value. It is favored by people, so it has the reputation of women's metal and is widely used as jewelry, decorations, silverware, tableware, congratulations Gifts, medals and coins. There are mainly three grades of silver for traditional decoration: sterling silver, 958 silver and 925 silver, among which 958 silver and 925 silver are binary alloys composed of copper as an alloying element. No matter what brand of silver it is, there is a problem of easy discoloration. In the atmospheric atmosphere, the surface of the jewelry will lose its white luster after a period of time and turn yellow and black, which seriously affects the ornamental effect of the jewelry. [0003] In order to improve the an...
