Problems solved by technology

[0005] Therefore, the shortcoming of the thermal transfer film made of the above-mentioned PET flakes is: there is not only the problem of melting of the PET flakes under the action of high temperature, but also the need to protect the particularity of the transferred film made of various physical properties from damage, deformation and Damaged, instant thermal transfer, printing effect is unstable under strong adhesion, using the existing thermal transfer film, it is impossible to apply thermal transfer printing products on the specific transferees with different physical properties, With the existing thermal transfer film, it must be transferred to the object to be transferred by high temperature and high pressure, and the damage, deformation and breakage of the printed surface cannot be avoided. In particular, the problem of limited mass production

Embodiment 1

[0025] Dye-sublimation transfer film, including a base film made of polyethylene terephthalate, the surface of the base film is coated with a printing layer, the thickness of the base film is 25 μm, and the thickness of the printing layer is 2 μm. The printing layer is composed of pigments, Polyurethane, butanone and cellulose acetate are mixed, soaked, dispersed and dissolved at high speed, and the weight ratio of pigment, polyurethane, butanone and cellulose acetate is 20:25:39:0.1.

[0026] The light fastness, water resistance and scratch resistance of the transfer film are tested to achieve the following results. The light fastness test is measured at 60°C using a QUV fading instrument. It is required that the transfer film can pass the 200-hour exposure test without cracks or peeling off. layers, fading or discoloration. After 200 hours, the sample reaches level 4 of the gray standard. The comparative standard is: ISO Gray Scale For Coiour Change; the water resistance tes...

Abstract

The invention belongs to the technical field of thermal transfer films, in particular to a thermal dye sublimation transfer film and a preparation method thereof. The thermal dye sublimation transfer film comprises a base film, wherein a printing layer is coated on the surface of the base film. The thermal dye sublimation transfer film has excellent light resistance, water resistance and scratch resistance, the transfer is extremely convenient by employing the thermal dye sublimation transfer film, and the requirement on transfer conditions is extremely low.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer printing films, and in particular relates to a thermal sublimation transfer printing film and a preparation method thereof. Background technique [0002] Generally speaking, using the existing transfer film, the transfer is carried out by vacuum adsorption and high temperature (200°C~240°C), or transfer is carried out under high temperature and high pressure. The above-mentioned prior art requires air vacuum, which is cumbersome, and is limited to one transfer film for transfer, so the work efficiency is very low, and the productivity is limited. In addition, equipment and equipment required for air vacuum are required, and the cost is high. When transferring by vacuum adsorption and high temperature, film damage often occurs, the transfer surface is deformed, the concentration and clarity of textures and the like are reduced, and the defect rate is high. . [0003] Especially when the ...
