Embodiment 1

[0015] After the solder wire drawing process, a coating process is set, and air drying is performed after the coating process. The proportion of the solution used in the coating process is as follows: containing 1 × 10 -4 mol / L tris(8-hydroxyquinoline)aluminum (fluorescent material), 0.05% polyvinyl butyral (film-forming material), and glycerol as a solvent.

[0016] After the solder wire is coated with the solution, the fluorescent substance on the solder wire is relatively clear, the film forming speed is fast, and the anti-counterfeiting effect is excellent.

Embodiment 2

[0018] After the solder wire drawing process, a coating process is set, and air drying is performed after the coating process. The proportion of the solution used in the coating process is as follows: containing 1 × 10 -4 mol / L tris(2-thienyltrifluoroacetone)-(1,10-phenanthroline)europium (luminescent material), 0.04% polyvinyl butyral (film-forming material), solvent is glycerol alcohol.

[0019] After the solder wire is coated with the solution, the fluorescent substance on the solder wire is relatively clear, the film forming speed is fast, and the anti-counterfeiting effect is excellent.

Embodiment 3

[0021] After the solder wire drawing process, a coating process is set, and air drying is performed after the coating process. The proportion of the solution used in the coating process is as follows: the composition contains 1×10 -6 mol / L1, 5-diphenyl-3-(4-chloro)phenyl-2-pyrazoline (luminescent material), 0.08% sodium carboxymethyl cellulose (film-forming material), solvent is glycerol alcohol.

[0022] After the solder wire is coated with the solution, the fluorescent substance on the solder wire can be easily identified, the film forming speed is fast, and the anti-counterfeiting effect is excellent.

Abstract

The invention discloses a soldering tin wire with a counterfeit identification and a production method thereof. The production method of the soldering tin wire comprises the following steps of: immersing the soldering tin wire obtained by a wiredrawing procedure into a solution which has luminescence characteristics after the film is formed; and then air drying to obtain a counterfeit soldering tin wire with a luminescence performance. The solution with the luminescence characteristics contains 1*10<-4>-1*10<-6> fluorescent material, a film-forming material with the concentration of 0.01-0.1 percent and the balance of water or organic solvent, wherein the organic solvent is one or more of organic alcohols, organic ketones and organic ethers; and the film-forming material comprises one or several of sodium carboxymethyl cellulose, polyvinyl butyral and polyving akohol. The soldering tin wire can achieve the counterfeit function by adopting a chemical method; the prepared soldering tin wire has the luminescence performance; the counterfeit identification is not easy to replace and easy to identify; the counterfeit soldering tin wire has simple production method and low cost; and manual operation is nearly needed in the production process without influencing production efficiency.

Description

technical field [0001] The invention relates to an anti-counterfeit solder wire and a manufacturing method thereof. Background technique [0002] Anti-counterfeiting is a preventive technology adopted by enterprises in order to protect the corporate brand, protect the market, and protect the legitimate rights and interests of consumers in the current situation of lack of social integrity and counterfeit and shoddy goods that disrupt the normal operation of the enterprise and damage the interests of the enterprise and consumers. measure. While enterprises make full use of anti-counterfeiting technology to combat counterfeiting, rectify and regulate the market, they can also enhance the social image of enterprises and their products. At the same time, enterprises should take anti-counterfeiting as an opportunity, take effective anti-counterfeiting measures as a kind of strategic investment of enterprises, formulate and gradually realize anti-counterfeiting work goals in a pla...
