[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0017] As shown in the drawings, the embodiments of the present application comprise: Figs. 1-3

[0018] A high-temperature heat protection heat sublimation transfer paper, comprising a base paper 1, a grid support layer 2, a grid-shaped cavity 3, an elastic bag body 4, an inert gas 5, an aluminum foil pressing strip 6, a heat-conducting metal paint layer 7, a heat sublimation dye adsorbing cellulose layer 8, and a dye moisture absorption layer 9. The surface of the base paper 1 is glued with the grid support layer 2. The grid support layer 2 has a plurality of parallelly arranged grid-shaped cavities 3. The grid-shaped cavities 3 are filled with the elastic bag body 4. The elastic bag body 4 is provided with a dot-shaped fusion portion 10 along the center line. The dot-shaped fusion portion 10 separates the elastic bag body 4 into a first bag portion 41 and a second bag portion 42. The first bag portion 41 is filled with the inert gas 5. The second bag portion 42 is externally pressed with the aluminum foil pressing strip 6. The upper surface of the grid support layer 2 is sprayed with the heat-conducting metal paint layer 7 covering the elastic bag body 4 and the aluminum foil pressing strip 6. The heat-conducting metal paint layer 7 is externally coated with the heat sublimation dye adsorbing cellulose layer 8. The heat sublimation dye adsorbing cellulose layer 8 is externally covered with the dye moisture absorption layer 9.

[0019] Further, the dot-shaped fusion portion 10 fuses the upper wall and the lower wall of the elastic bag body 4 to form a plurality of dot-shaped nodes. The dot-shaped nodes form through openings between the dot-shaped nodes. The upper wall and the lower wall of the elastic bag body 4 are in interference fit closure with each other at the through openings due to the connection of the dot-shaped nodes. The through openings are closed. When the inert gas 5 expands due to heat, the through openings are opened under the expansion pressure, and the inert gas 5 enters the second bag portion 42 from the first bag portion 41.

[0020] Further, the grid support layer 2 is composed of a metal mesh plate or a hard cardboard. The width of the grid-shaped cavity 3 is in the range of 5-16 mm.

[0021] Further, the inert gas 5 is helium or argon.

[0022] ​Further, when the inert gas 5 expands in the high-temperature environment during thermal sublimation transfer, the volume of the aluminum foil 6 is equal to the volume of the elastic bag 4, which is equal to the volume of the grid-shaped cavity 3. Assuming that the design high-temperature protection threshold of the thermal sublimation transfer paper is 199℃, in order to achieve high-temperature protection at 200℃, the following technical ideas are used to design the internal structure:

[0023] Under the theoretical conditions of the ideal gas state equation and constant pressure, when the temperature of helium changes from room temperature 25℃ to 200℃, the volume of helium increases by a factor of 1.59. The volume of the grid-shaped cavity 3 is set to be 2.2 times the volume of helium at room temperature, so the volume of the pressure strip is 0.61 times the volume of helium at room temperature. In this way, a uniform helium heat insulation layer is formed, which can provide good high-temperature protection when the temperature exceeds 200℃.

[0024] Generally, high-temperature protection occurs in a local area of the thermal sublimation transfer region. In order to further reduce the temperature in the high-temperature area, the heat-conducting metal paint layer 7 contains heat-conducting metal powder, including but not limited to copper powder, aluminum powder, and iron powder. The thickness of the heat-conducting metal paint layer 7 is not less than 100μm. When high-temperature protection occurs, the local high temperature is transmitted to the entire surface of the thermal sublimation transfer paper through the heat-conducting metal paint layer 7.

[0025] As the temperature returns, the expanded volume of helium returns to normal.

[0026] In conclusion, the utility model provides a kind of high temperature thermal protection thermal sublimation transfer paper, by adding grid support layer constructs grid-shaped cavity, utilize the high temperature expansion characteristics of inert gas to control the filling rate of elastic capsule in grid-shaped cavity, to rapidly establish heat insulation gas layer when local high temperature overheating, delay the transmission of overheating temperature to thermal sublimation dye adsorbed cellulose layer, on this basis, contact effect of aluminium foil batten and heat-conducting metal paint layer is used to control the rapid export of local high temperature, to form effective local high temperature material protection mechanism, significantly improve the transfer printing effect of thermal sublimation dye.
