Description

Pigment type aromatic fluorescent ink and preparation method thereof

technical field

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

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.

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 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. Therefore, it is very important to add reasonable flavors to fluorescent compounds of different colors.

Therefore, there is a need in the art for a method for matching suitable fragrances for fluorescent color pastes with good dispersion stability, and finally, fluorescent water-based inks with different colors and different fragrances can be obtained.

Detailed ways

The technical solutions of the present invention will be further described below according to specific embodiments. The protection scope of the present invention is not limited to the following examples, which are listed for illustrative purposes only and do not limit the present invention in any way.

The pigment type aromatic fluorescent ink of the present invention, by weight percentage, its component comprises: 40-60% of fluorescent color paste, 13-20% of moisturizing agent, 0.5-0.8% of flavor, 0.1-0.18% of flavor slow-release agent, assistant 0.1-0.2% of solvent, 0.01-0.2% of defoamer, 0.1-0.2% of preservative, and the balance is water.

The fluorescent color paste used in the present invention is one of blue fluorescent color paste, yellow fluorescent color paste, orange fluorescent color paste and pink fluorescent color paste.

The humectant used in the present invention is glycerin, propylene glycol, or a mixture of glycerin and propylene glycol.

The essence used in the present invention is the water-soluble essence of daily cosmetic grade, and the water-based essence of daily cosmetic grade belongs to synthetic essence, and the composition of its component is also different according to the difference of its fragrance type, and synthetic essence can be made up of dozens of kinds Compounded from hundreds of components. Therefore, due to the complex composition of the essence, it is extremely easy to cause the stability of the pigment-type fluorescent color paste to deteriorate, mainly in the shortening of its storage time, the reduction of its writing performance, and especially the shortening of the intermittent writing time.

The fragrance slow-release agent used in the present invention is a macromolecular polymer with any one or more groups of OH-, -SH, -NH ₂ , -CHO, -COOH and -H ₃ PO ₂ .

The co-solvent used in the present invention is a surfactant selected from alkylphenol polyoxyethylene ethers.

The defoaming agent used in the present invention is one of polyether, polyorganosiloxane and polyether modified organosiloxane.

The preservative used in the present invention is 1,2-benzisothiazol-3-one or isothiazolone.

The water used in the present invention is deionized water.

According to the composition analysis of different fluorescent pigment compounds and different flavor essences, the present invention uses them together, and additionally adds flavor slow-release agents, co-solvents, etc. to maintain their original stability and correspondingly increase the fragrance lasting time of the essence. The final finished fluorescent ink formulated with different ratios was used to fill the finished fluorescent marker pen for testing of writing performance.

The final experimental test results found that the intermittent writing performance of the formulated pigment-based aromatic fluorescent ink, such as intermittent writing time, is better than that of the fluorescent ink formulated with the same pigment-based fluorescent color paste. Therefore, it shows that the pigment-type aromatic fluorescent ink provided by the present invention is very stable.

Unless otherwise defined, the terms used in the present invention have meanings commonly understood by those skilled in the art.

The present invention will be described in further detail below through examples.

Example

Example 1

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.

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 writing and on the paper after writing, it will emit a fresh blueberry fragrance.

Example 2

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.

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 on the paper after writing, it will emit a fresh banana fragrance.

In summary, the pigment-type aromatic fluorescent ink, the final product obtained in the present invention, has good stability. It can be placed at a high temperature of 50°C for 60 days, and at room temperature for more than 2 years, and can still write normally. Under normal circumstances, the initial writing can be normal after 120 days of opening the pen, and the intermittent writing experiment is carried out in an environment with a temperature of 25°C and a humidity of 50%, and the longest writing can still be written normally after 72 hours of opening. Moreover, fresh and fruity fragrances will be emitted during the writing process and on the paper after writing, so the pigment-type aromatic fluorescent ink of the present invention has high stability.
