Problems solved by technology

In addition, pigment-based fluorescent inks have properties such as water resistance, acid and alkali resistance, and weather resistance, but pigment-based fluorescent compounds are very difficult to disperse in water-based systems, and if other compounds are exceptionally added to the dispersed fluorescent concentrate, it is very easy to cause Agglomeration occurs

Embodiment 1

[0037]

[0038] First add glycerin and deionized water into the reaction kettle at the same time, and then stir at room temperature for 0.5-1 hour. Then add the blue fluorescent concentrate and stir at the same speed for 1 hour.

[0039] Under the condition of stirring, add BrijC20 polyoxyethylene ether, daily chemical grade water-based blueberry flavor and flavor slow-release agent vinyl cage polysilsesquioxane in turn, stir at room temperature for 2-4 hours, then reduce the stirring speed and The antifoaming agent polydimethylsiloxane was added to defoam, and finally the preservative 1,2-benzisothiazol-3-one was added to prepare the blue blueberry-flavored pigment-type aromatic fluorescent ink. Filled fluorescent markers The filled fluorescent markers can be written normally after 120 days in normal environment, and the intermittent writing experiment is carried out in an environment with a temperature of 25°C and a humidity of 50%. Write normally. And in the process of...

Embodiment 2

[0041]

[0042] First add glycerin, propylene glycol and deionized water into the reaction kettle at the same time, and then stir at room temperature for 0.5-1 hour. Then add yellow fluorescent color paste and stir at the same speed for 1 hour.

[0043] Under the condition of stirring, add 100% polyoxyethylene stearate, daily chemical grade water-based banana flavor and flavor slow-release agent amino cage polysilsesquioxane in turn, stir at room temperature for 2-4 hours, then reduce the stirring Then add antifoaming agent polyvinyl siloxane to defoam, and finally add preservative isothiazolinone to make yellow banana-flavored pigment-type aromatic fluorescent ink. The filled fluorescent marker pen can be written normally after 120 days in normal environment, and the intermittent writing experiment is carried out in an environment with a temperature of 25°C and a humidity of 50%, and it can still write normally after 72 hours of opening. And in the process of writing and ...

Abstract

The invention provides pigment type fragrant fluorescent ink. The pigment type fragrant fluorescent ink is prepared from, by weight, 40-60% of fluorescent color paste, 13-20% of a humectant, 0.5-0.8% of essence, 0.1-0.18% of an essence slow-release agent, 0.1-0.2% of cosolvent, 0.01-0.2% of a defoaming agent, 0.1-0.2% of preservative and the balance water. The invention further provides a preparing method for the pigment type fragrant fluorescent ink. As the essence slow-release agent is added into the ink, the fragrance time of the essence in the ink is prolonged, and the cosolvent is added to solve the problem that the stability of the fluorescent ink is reduced after the essence is added, so that fluorescent compounds different in color and fragrance type are high in suitability, and the pigment type fragrant fluorescent ink has high stability.

Description

technical field [0001] The invention relates to a new formula of fluorescent water-based ink, in particular to a pigment-type aromatic fluorescent ink and a preparation method thereof. Background technique [0002] Fluorescent water-based ink refers to water-based ink with fluorescent effect, mainly by adding visible fluorescent compound pigments with photoinduced excitation in the process of preparing fluorescent ink color paste. Fluorescent compound pigments can absorb light energy and produce atomic energy level transitions, and then release The absorbed energy emits fluorescent photons, thus having a fluorescent effect. [0003] Fluorescent water-based ink can be used in fluorescent marker pens, which can mark the key points of books without covering the original handwriting, so it is very popular among consumers. In addition, pigment-based fluorescent inks have properties such as water resistance, acid and alkali resistance, and weather resistance, but pigment-based fl...
