[0003] Chinese patent CN202410465311.9 discloses a method for preparing photoluminescent powder, ceramic ink and invisible anti-counterfeiting ceramic, wherein the ceramic ink comprises, by weight, 2 to 6 parts of photoluminescent powder, 84 to 96 parts of solvent, 0.5 to 5 parts of dispersant and 1.5 to 5 parts of surfactant. However, since the pigment particles used to make the photoluminescent body are relatively large, after the ink is prepared, the particle size of the ink is relatively large and is easy to settle, causing discoloration and stratification, and easily clogging the nozzle.

[0004] Photoluminescent coating ink is an important variety of coating ink and its demand is growing day by day. Therefore, there is an urgent need for a photoluminescent ink with good stability and fluidity. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a photoluminescent heat transfer ink with a metallic luster and high luminous efficiency, high durability and stability, which solves the problem that the current photoluminescent ink has a large particle size and is easy to settle, causing discoloration and stratification and easily clogging the nozzle.

[0006] To achieve the above purpose, the specific technical solutions of the present invention are as follows: The invention provides a photoluminescent heat transfer ink with metallic luster, which comprises the following components by mass percentage: 20% to 30% of metallic photoluminescent pigment paste, 50% to 60% of water-based resin, 5% to 10% of moisturizer, 0.5% to 2% of acid-base regulator, 0.5% to 5% of surfactant, 0.1% to 1% of bactericide, and the balance of deionized water.

[0007] Furthermore, the water-based resin is a water-based polyurethane emulsion, and the particle size is less than or equal to 100 nm.

[0008] Furthermore, the moisturizing agent is one or more of ethylene glycol, propylene glycol, and glycerol.

[0009] Furthermore, the surfactant is a fluorinated nonionic surfactant FS-31 (DuPont, USA).

[0010] Further, the fungicide is a mixture of salicylic acid, 1,2-benzisothiazolinone and 8-hydroxyquinoline, and the mass ratio of salicylic acid, 1,2-benzisothiazolinone and 8-hydroxyquinoline is 2:2:1.

[0011] Furthermore, the acid-base regulator is one or more of sodium hydroxide, potassium hydroxide, ammonia water, and triethylamine.

[0012] Furthermore, the metal photoluminescent pigment paste is an inorganic-organic mixed photochromic pigment dispersion, and the preparation method is as follows: (1) Add nano glass fiber, nano silicon dioxide, cerium sulfide, lanthanum sulfide, strontium carbonate and copper phthalocyanine blue to methanol and mix them evenly, then dry them at 80-120° C. for 18-24 hours, and grind them in a ball mill for 2-4 hours to obtain material 1; (2) sintering material 1 in a hollow carbon nanotube reducing atmosphere at 1300-1500° C. for 3-4 hours to obtain material 2; (3) Place material 2 in a ball mill and grind it for 2 to 4 hours, then mix it with the organic pigment dispersion and stir it evenly to obtain a metallic photoluminescent pigment paste.

[0013] Furthermore, the mass ratio of the nano glass fiber, nano silicon dioxide, hollow carbon nanotube, cerium sulfide, lanthanum sulfide, strontium carbonate and copper phthalocyanine blue in step (1) and step (2) is 1:1.5:1:3:3:4.5:2.

[0014] Furthermore, in step (1), the diameter of the nano glass fiber is less than 20 nm and the length is less than 200 nm, the particle size of the nano silicon dioxide is less than 70 nm, the particle size of the cerium sulfide is less than 120 nm, the particle size of the lanthanum sulfide is less than 150 nm, the particle size of the strontium carbonate is less than 200 nm, and the particle size of the copper phthalocyanine blue is less than 200 nm.

[0015] Furthermore, the hollow carbon nanotubes in step (2) have a diameter less than 10 nm and a length less than 200 nm.

[0016] Furthermore, the organic pigment dispersion in step (3) is one or more of pigment red 254, pigment yellow 180, and pigment blue 60 aqueous dispersions, the pigment particle size is less than 120 nm, and the solid content is 20% to 35%.

[0017] Furthermore, the rotation speed of the ball mill in steps (1) and (3) is 500 to 1000 rpm.

[0018] Nano-silica has the optical property of resisting ultraviolet rays. Adding nano-silica in the preparation process of metal photoluminescent pigment paste can improve the ink's anti-aging, strength and chemical resistance, improve the ink's strength and smoothness, and keep the color from fading for a long time; at the same time, it can form a coating effect on the pigment, which can resist ultraviolet aging and heat and increase the ink's weather resistance.

[0019] Nano glass fiber is a nano-level fiber made of glass balls or waste glass through high-temperature melting, drawing and other processes. It has the advantages of good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, etc. Adding nano glass fiber in the preparation process of metal photoluminescent pigment paste can not only enhance the strength and stability of the pigment paste, improve the wear resistance and overall mechanical properties of the ink coating, but also help improve the light propagation of the ink in the luminescent material due to the high transparency of nano glass fiber, and enhance the overall luminescent effect; at the same time, it can also act as a support agent to make the luminescent material more evenly distributed, effectively preventing the luminescent material from settling during the drying process of the ink, thereby improving the stability of the ink and the quality of the coating.

[0020] Solid content is an important indicator for measuring the concentration of pigment dispersion. A higher solid content means that the pigment paste has higher color strength and hiding power, but it may also affect its fluidity and coating performance; a lower solid content makes the pigment paste easier to apply, but the color strength and hiding power may be relatively weak. The solid content of the organic pigment in the present invention is 20% to 35%, which is moderate and will not affect the fluidity and coating performance of the ink, while also having certain strength and hiding power.

[0021] The present invention combines inorganic luminescent materials such as cerium sulfide, lanthanum sulfide and strontium carbonate with organic materials such as copper phthalocyanine blue. Different inorganic and organic luminescent materials can adjust the color of the luminescence to achieve richer color display; inorganic materials provide higher stability and electron transport performance, and organic materials have good luminescent performance and color adjustability. Combining the characteristics of inorganic and organic luminescent materials, more efficient luminescence can be achieved; at the same time, inorganic materials have good thermal stability and chemical stability, and can improve the stability of the entire luminescent system after being combined with organic materials.

[0022] The principle of the metal photoluminescent pigment paste is photoluminescence, which refers to the luminescence phenomenon caused by the use of light to excite the luminescent body. After three main stages of absorption, energy transfer and light emission, the electrons in the luminescent material absorb the energy of the photon and transition to a higher energy level. When the electrons return to the ground state, they release energy, which is emitted in the form of light, thereby generating the luminescence phenomenon. In the preparation process of the metal photoluminescent pigment paste, in step (2), the material 1 is sintered in the hollow carbon nanotube reducing atmosphere. The reducing atmosphere helps the metal ions in cerium sulfide and lanthanum sulfide to change their valence state under the high-temperature reducing atmosphere. The change in the valence state of the metal ions will change their energy level structure. In the photoluminescence process, the transition of electrons between different energy levels will generate luminescence of a specific wavelength. When the metal ions are reduced from a high valence state to a low valence state, their energy level structure changes, resulting in the movement of the luminescence wavelength, thereby affecting the optical properties and luminescence characteristics of the pigment.

[0023] Hollow carbon nanotubes have a large specific surface area and a special nanostructure. The hollow structure of carbon nanotubes also provides a stable accommodation space for pigment particles. As the sintering process proceeds, the surface energy of the pigment particles increases under high temperature conditions, and the atoms or molecules in the pigment particles diffuse to the surface and interior of the hollow carbon nanotubes, making it easier for them to physically contact and adsorb with the carbon nanotubes. The pigment particles are attached to the carbon nanotubes through physical adsorption such as van der Waals force and electrostatic attraction. The pigment particles may gradually wrap around the carbon nanotubes to form a composite structure similar to a core-shell structure, which can improve the strength and stability of the pigment. During the high-temperature sintering process, chemical bonding occurs between the pigment particles and the hollow carbon nanotubes. The functional groups such as carboxyl and hydroxyl groups on the surface of the carbon nanotubes react chemically with the active groups on the surface of the pigment particles to form covalent bonds or ionic bonds. This chemical bonding can also greatly improve the strength and stability of the pigment.

[0024] In addition, carbon nanotubes have a high light capture ability. Adding them to photoluminescent heat transfer ink can enhance the luminescent material's absorption of external light sources, thereby enhancing the brightness and durability of photoluminescence. The carbon nanotube component also has extremely high thermal conductivity, which can effectively disperse the heat generated by the luminescent material during operation and prevent overheating, thereby extending the life of the luminescent material and improving the stability of the ink, reducing the occurrence of ink discoloration, stratification and nozzle clogging.

[0025] The present invention provides a photoluminescent heat transfer ink with a metallic luster, and a specific preparation method comprises the following steps: S1: mixing the acid-base regulator and the water-based resin and stirring them evenly to obtain a mixed solution 1; S2: adding deionized water, a surfactant, and a moisturizer to the mixed solution 1 of step S1 in sequence, and stirring evenly to obtain a mixed solution 2; S3: adding the metal photoluminescent pigment paste and the fungicide to the mixed solution 2 of step S2 in sequence, mixing and stirring to obtain a mixed solution 3; S4: filtering the mixed solution 3 of step S3 using a filter membrane with a pore size of 0.45 μm to obtain a filtrate 4; S5: degassing the filtrate obtained in step S4 under a vacuum degree of 0.06-0.1 MPa for 10-40 minutes to obtain a photoluminescent heat transfer ink with a metallic luster.

[0026] The heat transfer ink is sprayed on the PET transfer film in the order of color first and then white by a commercial digital printing machine, and then the pattern part is adhered with hot melt adhesive powder, and the hot melt adhesive powder that is not firmly adhered is removed through a powder shaking step to obtain a heat transfer film to be transferred. The pattern side of the heat transfer film is placed close to the fabric, and a heat press is used at a temperature of 150℃ to 180℃ for 8 to 25 seconds, and then the heat transfer film is torn off to obtain the heat transfer fabric.

[0027] The present invention prepares a photoluminescent heat transfer ink with a metallic luster, wherein the heat transfer ink contains a photoluminescent pigment paste, wherein the ink contains components such as nano glass fibers and carbon nanotubes, and is a photoluminescent heat transfer ink with a metallic luster with high luminous efficiency, high durability and stability. Compared with traditional heat transfer inks, the ink has photoluminescent properties, and due to its special composition, has higher ink stability and coating quality, and has a good photoluminescent effect. The fabric printed with this ink overcomes the multiple defects of traditional technologies and opens up new possibilities for the application of protective clothing, industrial fabrics and other special working equipment.

[0028] The beneficial effects of the present invention are: The invention provides a photoluminescent heat transfer ink with a metallic luster and a preparation method thereof. Nano glass fibers are added during the preparation of the metal photoluminescent pigment paste, thereby improving the wear resistance and overall mechanical properties of the ink coating, and helping to improve the light propagation of the ink in the luminescent material, thereby enhancing the overall luminescent effect. The ink can also act as a support agent, thereby making the luminescent material more evenly distributed, effectively preventing the luminescent material from settling during the ink drying process, and improving the ink stability and coating quality. The added carbon nanotubes can enhance the luminescent material's absorption of external light sources, enhance the brightness and durability of the photoluminescence, and have extremely high thermal conductivity, thereby effectively dispersing the heat generated by the luminescent material during operation, preventing overheating, extending the life of the luminescent material, and improving the long-term stability of the ink. By preparing the metal photoluminescent pigment paste, the application effect of the photoluminescent heat transfer ink is greatly improved, and its application scenarios are expanded, such as application in protective clothing, industrial fabrics, and other special operating equipment.
