A kind of blending agent for tin carving handicraft welding process and preparation method thereof

Abstract

The invention discloses a dispensing agent for a tin carving craft welding process and a preparation method of the dispensing agent. The dispensing agent comprises the following components in a mass ratio: 20-30 parts of a fatty acid group non-ionic surfactant, 18-22 parts of an aromatic non-ionic surfactant, 10-12 parts of alkanolamine, 3-5 parts of a phthalic acid activator, 2-4 parts of carbazole and 15-20 parts of an organic acid composition activator. Through the multiple non-ionic surfactants, the capability of the prepared dispensing agent to reduce the surface tension of molten solderduring the welding process can be effectively improved; meanwhile, the bonding wettability between the molten solder and a tin carving craft is high, the emulsification cleaning capability is relatively high, and the welding tightness and integrity can be improved; among the components, alkanolamine and the phthalic acid activator are matched with other components, so that the weld corrosion, caused by the residue of the molten solder, of the tin carving craft after the completion of welding can be avoided; and the surface structure stability and the high strength of the welded tin carving craft can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of making tin carving handicrafts, in particular to a compounding agent for the welding process of tin carving handicrafts and a preparation method thereof. Background technique [0002] Tin is the fourth precious metal next to gold, silver, and copper. It has the appearance characteristics of "bright as a mirror, color like silver" and anti-alkali, non-toxic, and stainless anti-corrosion properties. Tin carving crafts are mainly based on Tin ingots with a purity of 99.99% are made as raw materials. Tin carving crafts adopt traditional manual techniques, and go through dozens of steps such as casting, blanking, precision casting, welding, modeling, grinding, polishing, engraving, assembly, and trimming. The process is refined. [0003] During the welding process of tin carving crafts, the oxide film on the surface of tin carving crafts, solder and other impurities directly affect the quality and aesthetics ...

Problems solved by technology

[0003] During the soldering process of tin carving handicrafts, the oxide film on the surface of tin carving handicrafts, solder and other impurities directly affect the quality and aesthetics of finished tin carving handicrafts. Mutual wetting and tight bonding is the key point of welding. At present, in the soldering process of tin carving crafts, rosin, alcohol and water are usually used to reduce the surface tension of molten solder. However, rosin perfume has poor soldering ability. , the shortcoming of poor insulation stability cannot improve the welding quality of tin carving handicrafts well. Therefore, the present invention proposes a compounding agent for tin carving handicraft welding process and its preparation method to solve the deficiencies in the prior art.
