Abstract

The invention discloses a thermochromic process for noble metal. The thermochromic process comprises the following steps: firstly, plating a black primer on the surface of the noble metal; then, plating a forming coating of thermochromic paint on the basis of the black primer; finally, plating a protective layer, wherein the thermochromic coating has the effect of changing color with temperature. The thermochromic process is simple to operate, environmentally friendly and healthy; an obtained noble metal product is colorful and diversified, and the ornamental property and collection value of the noble metal product are greatly improved.

Description

technical field [0001] The invention relates to the field of precious metal processing, in particular to a temperature-sensitive discoloration process for precious metals. Background technique [0002] Today, people's living standards are constantly improving, and people's entertainment life and personal collection hobbies are becoming more and more extensive. Jewelry, precious metals and other accessories are increasingly becoming the embodiment of people's pursuit of quality of life. For precious metals, such as gold, silver, K gold, platinum, etc., people's requirements for them can no longer be satisfied with the previous relatively simple beautification, and colorful, precious metals with more ornamental value are deeply loved by the public; at the same time, precious metals are not only As an entertainment accessory, it also has the value of collection and investment, and the quality of its use and preservation is also the content that people pay attention to. [000...
