Special water-based fluorescent ink for fluorescent screen and preparation method of ink

Abstract

The invention discloses special water-based fluorescent ink for a fluorescent screen and a preparation method of the special water-based fluorescent ink, and the special water-based fluorescent ink comprises the following components in percentage by weight: 15-35% of a fluorescent color paste, 2-8% of a wetting dispersant, 10-20% of a covering, 0.5-5% of an anti-settling assistant, 0.03-0.1% of bactericide, 2-8% of film-forming resin, 1-5% of a wetting leveling agent and the balance of deionized water. The preparation method of the water-based fluorescent ink comprises the following steps: adding the wetting dispersant and the deionized water into a reaction kettle at the same time, then stirring for 1-2h at room temperature, and adding the fluorescent color paste; and under the conditionof stirring, sequentially adding the covering and the anti-settling additive, and finally adding the bactericide, the film-forming resin and the wetting leveling agent. The formula is reasonable in design, writing on the fluorescent screen can be smooth and smooth, the color is bright, handwriting is clear, and no trace is left after erasing; and the ink is also suitable for writing on smooth surfaces of glass plates, plastic plates, blackboards and the like with various colors, and the dried color is rich and bright.

Description

technical field [0001] The invention relates to the technical field of fluorescent inks, in particular to a special water-based fluorescent ink for fluorescent plates and a preparation method thereof. Background technique [0002] Fluorescent boards are written on fluorescent boards with fluorescent pens of various colors, plugged in, and written on acrylic panels, tempered glass panels or tempered glass through the LED highlight patch light source on the side of the fluorescent boards. Words are issued in different colors to achieve advertising effects. [0003] In the prior art, the disclosed cases of water-based fluorescent inks are found by retrieval: Case 1) The patent specification whose publication number is CN105462359B discloses a preparation method of water-based color fluorescent inks, adding deionized water into an ultrasonic disperser with stirring , under the action of stirring and ultrasound, sequentially add dyes, film-forming agents, wetting agents, defoame...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned fluorescent inks in the prior art have deficiencies during use. The first is that the color is dull after being written on the fluorescent board, and it is not easy to scrub; It has a better display effect when it is energized, and it is invisible when it is not energized, so it is only suitable for advertising at night when it is energized, and its use is greatly restricted.
