Embodiment 1

[0040] A halogen-free, water-based, room-temperature phosphorescent material, which uses sodium polyvinylbenzenesulfonate as a raw material and has a number-average molecular weight of 7000, is dissolved in water to prepare an aqueous solution with a mass fraction of 2%.

[0041] Use the solution prepared above as a raw material for printing, and the specific process is as follows: use 2% mass fraction of sodium polyvinylbenzenesulfonate aqueous solution to carry out letterpress printing on paper, and after printing, dry the paper at 70 degrees for 1 hour, and then it can be printed on A printed pattern with green fluorescence-green phosphorescence is left on the paper.

[0042] When the above patterns are directly placed in the air, due to the water absorption of the paper, the clusters will gradually lose their room temperature phosphorescent properties. In order to maintain the phosphorescent properties of the pattern, it can be protected by overmolding, so that the pattern...

Embodiment 2

[0045] A halogen-free, water-based room-temperature phosphorescent material, which uses polyvinylbenzenesulfonic acid as a raw material and has a number-average molecular weight of 7000, is dissolved in water to prepare an aqueous solution with a mass fraction of 0.2%.

[0046] The solution prepared above is used as a raw material for printing, and the specific process is as follows: use 0.2% mass fraction of polyvinylbenzenesulfonic acid aqueous solution to inkjet print on the ethylene terephthalate film, and then print the film After drying at 90 degrees for 15 minutes, a green fluorescent-green phosphorescent printing pattern can be left on the film.

[0047]After plasticizing the film, a polymer film with room temperature phosphorescent patterns can be formed. Under the 365nm ultraviolet laser, the pattern shows green phosphorescence for 1.5 seconds after the light is turned off.

Embodiment 3

[0049] A method for preparing a halogen-free, water-based printing room-temperature phosphorescent material, using polyvinylbenzenesulfonic acid-melamine salt as a raw material, whose number average molecular weight is 7000, dissolving it in water, and preparing a polyvinylbenzenesulfonic acid-melamine salt with a mass fraction of 1%. aqueous solution.

[0050] Use the solution prepared above as a raw material for printing, and the specific process is as follows: use 1% by mass fraction of polyvinylbenzenesulfonic acid-melamine salt solution, screen-print on the self-adhesive film, and dry the paper at 70 degrees after printing After 1 hour, a printed pattern with blue fluorescence-blue-green phosphorescence can be left on the self-adhesive film.

[0051] Apply and protect with an acrylic paint that dries to form a long-lasting room temperature phosphorescent pattern on the self-adhesive film.

[0052] The prepared patterns and luminescent properties are as follows figure 2...

Abstract

The invention discloses application of polyvinyl benzene sulfonic acid or salt thereof as a room-temperature phosphorescent material. The structure of the polyvinyl benzene sulfonic acid or the salt thereof is represented by formula (I) shown in the description, and in the formula (I), R<+> is a hydrogen ion, a metal cation or an organic cation. The halogen-free and water-based printable room-temperature phosphorescent material disclosed by the invention has a very strong luminescent property at room temperature, the phosphorescent external quantum efficiency can reach 7-20%, the luminescent life is relatively long and is generally 1-3 seconds, and the luminescent range from blue to green can be covered; and the raw materials are simple and easy to obtain, the preparation method is simpleand rapid, the cost is low, no toxic halogen element exists, water can be used as a solvent in the whole processing process, and no organic solvent is used, so the method has obvious advantages in environmental protection, is suitable for industrial preparation and has good practical application and popularization value. .

Description

technical field [0001] The present invention relates to the technical field of organic luminescent materials, more specifically, relates to the application of polyvinylbenzenesulfonic acid or its salts as room temperature phosphorescent materials. Background technique [0002] Compared with fluorescence, room temperature phosphorescence has special time-delay characteristics. On the one hand, it can avoid the interference of short-lived fluorescence and scattered light. Anti-counterfeiting performance. [0003] However, there are certain limitations in the application of existing inorganic room temperature phosphorescent materials, such as rare earth long afterglow materials, which are difficult to play a role in anti-counterfeiting due to their long room temperature phosphorescent life and difficulty in processing. However, most organic room-temperature phosphorescent materials have the problems of difficult synthesis, difficult processing, and high pollution during proces...
