Problems solved by technology

[0002] At present, the commonly used jewelry surface protection mostly uses a layer of metal plating on the jewelry surface, such as gold, silver, platinum, copper, rhodium, etc., to prevent the wear and loss of luster on the jewelry surface. Although these materials are easy to mold, shape, and polish, this This kind of electroplating surface is actually easy to wear and lose luster, and the surface of electroplated jewelry is easily damaged, which will also reduce the life and value of jewelry, and this coating method is not suitable for the surface of gemstones, especially fragile gemstones. In addition, the electroplating process will produce a large number of toxic pollutants, causing environmental pollution

Abstract

The invention discloses a jewelry surface protective film prepared by adopting the following raw materials according to parts by weight: 0.5-3 parts of aminopropyltriethoxysilane, 1-5 parts of Al2O3, 15-25 parts of SiO2, 20-30 parts of isopropanol and 35-42 parts of water. The preparation method of the jewelry surface protective film comprises the following steps: (1) adding 10-15 parts (by weight) of the isopropanol in SiO2 micro-powder, carrying out even stirring, then adding Al2O3 micro-powder and the aminopropyltriethoxysilane, then adding the rest isopropanol and the water for even stirring, and finally forming a coating solution of the jewelry surface protective film; (2) cleaning a jewelry surface; (3) coating the coating solution of the jewelry surface protective film on the jewelry surface; and (4) drying, i.e. forming a layer of hard protective film on the piece of jewelry. The protective film has the advantages of high hardness, good protection effect, good protection against easy damage, simple production process and low cost.
