Problems solved by technology

[0004] However, due to the improvement of imitation technology and the popularity of anti-counterfeiting inks in the market, the explicit anti-counterfeiting technology is likely to be copied, and the invisible anti-counterfeiting technology mostly uses identification methods such as infrared and ultraviolet, which is not convenient and fast enough.

Embodiment 1

[0038] This embodiment provides a preparation method and application of reflective anti-counterfeiting ink, which specifically includes the following steps:

[0039] S1. Weighing: Weigh the components of the reflective anti-counterfeiting ink in proportion, and the mass percentages of each component are as follows: 500 mesh glass beads 6%, water-based polyurethane 46%, pure water 7%, absolute ethanol 30%, sulfur Diisooctyl Sodium Diethylsuccinate Anionic Surfactant 5%, Defoamer 3%, Fumed Silica 3%;

[0040] S2. Prepare the solvent: mix pure water and absolute ethanol to obtain a solvent, add water-based polyurethane and mix evenly;

[0041] S3. Stir once: add glass beads to the solution prepared in step S1, then stir once, the stirring speed is 600r / min, and the stirring time is 30min;

[0042] S4. secondary stirring: add diisooctyl sodium sulfosuccinate anionic surfactant, defoamer and anti-sedimentation agent to the solution stirred in step S2, carry out secondary stirring,...

Embodiment 2

[0046] This embodiment provides a preparation method and application of reflective anti-counterfeiting ink, which specifically includes the following steps:

[0047] S1. Weighing: Weigh each component of the reflective anti-counterfeiting ink in proportion, and the mass percentage of each component is as follows: 400 mesh glass beads 10%, water-based polyurethane 50%, pure water 10%, absolute ethanol 20%, sulfur Diisooctyl sodium diethyl succinate anionic surfactant 5%, defoamer 3%, fumed silica 2%;

[0048] S2. Prepare the solvent: mix pure water and absolute ethanol to obtain a solvent, add water-based polyurethane and mix evenly;

[0049] S3. Stir once: add glass beads to the solution prepared in step S1, then stir once, the stirring speed is 600r / min, and the stirring time is 30min;

[0050] S4. secondary stirring: add diisooctyl sodium sulfosuccinate anionic surfactant, defoamer and anti-sedimentation agent to the solution stirred in step S2, carry out secondary stirring...

Abstract

The invention discloses reflective anti-counterfeiting ink as well as a preparation method and application thereof. The reflective anti-counterfeiting ink comprises the following components in percentage by weight: 6-18% of glass beads, 36-60% of waterborne polyurethane, 6-10% of purified water, 10-40% of absolute ethyl alcohol, 1-5% of a dispersing agent, 2-3% of a defoaming agent and 1-3% of ananti-settling agent. The reflective anti-counterfeiting ink is prepared by weighing the components, preparing a solvent, performing stirring for a first time and performing stirring for a second time.The reflective anti-counterfeiting ink prepared by the invention can be applied to the aspect of silk-screen printing. According to the invention, the glass beads are added into the reflective anti-counterfeiting ink, then the glass beads have physical structures of high refractive indexes, and the reflective anti-counterfeiting ink has the characteristic of retroreflection and has an anti-counterfeiting effect. During use, printed images and texts can be identified through a flash shooting function of a mobile phone, and the identification method is convenient and rapid and has interactivity.

Description

technical field [0001] The invention relates to the technical field of inks, and more specifically, to a reflective anti-counterfeiting ink and a preparation method and application thereof. Background technique [0002] With the substantial improvement of social productivity, the imitation technology has also been continuously developed, which has led to the influx of various counterfeit and shoddy products into the market, which has had a great impact on genuine product enterprises and seriously disrupted the order of the market economy. [0003] In order to crack down on illegal acts of counterfeiting and selling counterfeit products, safeguard the legitimate rights and interests of enterprises and consumers, promote the healthy development of the market economy, and establish an atmosphere of honest transactions, it is necessary to improve anti-counterfeiting technology. The key to anti-counterfeiting technology is to extend the timeliness and uniqueness of anti-counterfe...
