Abstract

The invention discloses a jewelry surface protective film and a jewelry processing technology. The jewelry processing technology comprises the following steps of material selection, cutting, preforming and polishing. The invention also provides a jewelry surface protective film which is obtained by uniformly spraying the protective film treatment precursor on the jewelry surface subjected to dust removal and oil removal and then airing. Silicon dioxide sol and waterborne polyurethane are used as main raw materials of a protective film treatment precursor, the protective film is sprayed on the surface of jewelry and then naturally aired to form a colorless, transparent and high-hardness protective film layer, the thickness of the protective film is 200-350 nm, and the influence on the color of the jewelry is small; moreover, the protective film has good friction resistance and elasticity modulus, jewelry can be effectively separated from substances easy to rub in daily life, and the protective film has good durability in application scenes such as falling due to the good elasticity modulus.

Description

technical field [0001] The invention belongs to the technical field of jewelry processing, and in particular relates to a jewelry surface protective film and a jewelry processing technology. Background technique [0002] Jewelry can be divided into broad sense and narrow sense. Jewelry in the narrow sense refers to jade products. Jewelry in the broad sense includes gold, silver and natural materials (minerals, rocks, organisms, etc.) Collections are collectively referred to as jewelry. Today, in addition to natural gemstones and artificial gemstones, the concept of jewelry has been expanded to include gold, silver, jewelry, etc. [0003] In order to protect the pits, cracks, scratches and other defects on the surface of jewelry, to change or improve the visual color and surface finish of jewelry, surface treatment of jewelry is a common method. [0004] CN 104544802 A discloses a jewelry with a protective film and its manufacturing process, including a jade body, and the w...
