Problems solved by technology

[0003] Existing fluorescent inks are generally solvent-based fluorescent inks. Even if organic solvents such as benzene, formaldehyde, benzaldehyde, and cyclohexanone are used as dissolution carriers, not only the composition is complex, but also easy to settle, and it is difficult to store for a long time. Its VOC (volatile organic compounds, Organic volatiles) emissions are also high, affecting the health of printing workers and polluting the environment

Embodiment 1

[0023] Example 1 Aqueous fluorescent liquid

[0024] The aqueous fluorescent liquid was prepared according to the following mass percentages: fluorescent pigment 4%, water 46%, ethanol 50%.

[0025] Water and ethanol were firstly added to the reaction vessel, and then fluorescent pigments were added under the condition of 550 r / min, and the mixture was dispersed for 50 minutes for later use.

Embodiment 2

[0027] The environment-friendly fluorescent ink was prepared according to the following mass percentages: 10% of the aqueous fluorescent liquid in Example 1; 45% of the first acrylic emulsion; 0.5% of emulsified Brazilian wax; 0.2% of tego8300; 1% of ethylene glycol methyl ether; 21% of ethanol ; Water 22.3%.

[0028] Add the remaining water and ethanol to the reaction kettle, slowly add acrylic emulsion, emulsified Brazilian wax, tego830 and ethylene glycol methyl ether while stirring under the condition of 300r / min, adjust the rotation speed to 600r / min after adding, Disperse for 30min and filter with 200 mesh filter cloth.

[0029] The fluorescent ink prepared in this example has no abnormal toxicity, and can be used for printing on white cardboard and coated paper. The drying speed is fast, and the printing speed is 80m / min~120m / min.

Embodiment 3

[0031] Prepare environment-friendly fluorescent ink according to the following mass percentages: 14% of the aqueous fluorescent liquid in Example 1; 50% of the first acrylic emulsion; 1.6% of Brazilian wax; 0.1% of tego8300; 1% of ethylene glycol methyl ether; 17.3% of ethanol; Water 16%.

[0032] Add the remaining water and ethanol to the reaction kettle, slowly add acrylic emulsion, Brazilian wax, tego830 and ethylene glycol methyl ether while stirring under the condition of 300r / min. 30min, use 200 mesh filter cloth to filter.

[0033] The fluorescent ink prepared in this example has no abnormal toxicity, and can be used for white cardboard, coated paper, and corrugated paper printing. It has fast drying speed, excellent printing effect and full color. The printing speed is 80m / min~120m / min. Table 1 to Table 3.

Abstract

The invention provides environment-friendly fluorescent printing ink and a preparation method thereof. The fluorescent printing ink comprises the following components by weight percent: 0.1%-4% of a fluorescent pigment, 30%-60% of an acrylic emulsion, 0.2%-5% of a wear-resistant aid, 0.1%-1% of a de-foaming agent, 1%-5% of a film-forming agent, 15%-30% of ethanol and 15%-30% of water. Compared with an existing solvent type fluorescent printing ink, the fluorescent printing ink provided by the invention has the advantages that fluorescent color is bright, the dispersity is good, and no color migration is caused; the heat resistance is good, so that high temperature of 600 DEG C can be resisted; the water and ethanol are used as dissolving carriers, so that the ink is nontoxic, non-combustible, non-explosive and free of volatile organic gas; material components are simple and the cost is low.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting ink, in particular to an environment-friendly fluorescent ink and a preparation method thereof. Background technique [0002] Anti-counterfeiting inks include fluorescent inks, temperature-changing inks, optical color-changing inks, metal color-changing inks, anti-tampering inks and mirror-color-changing inks, among which fluorescent inks are widely accepted for their mature technology, stable quality, complete varieties, and diverse printing methods. Fluorescent inks are colorless, transparent or nearly white under ordinary light sources, and show no color when printed on paper or plastic films. Under ultraviolet light, they show different colors such as red, yellow, green, white, orange, and purple. [0003] The existing fluorescent inks are generally solvent-based fluorescent inks, that is, organic solvents such as benzene, formaldehyde, benzaldehyde, cyclohexanone, etc. are used as dissolvin...
