Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat transfer film, in particular to a heat transfer film for improving color adhesion. BACKGROUND

[0002] Heat transfer printing is a type of transfer printing, which is essentially a process of pre-printing patterns or characters on a substrate film to form a heat-mounted hidden, and then transferring the printed layer of patterns to the surface of the printed matter by heat and pressure. As a mature special printing technology, heat transfer printing is green and environmentally friendly, meets international non-toxic standards, does not require plate making or batch production, and can form multi-color patterns at one time without color matching. The printed patterns are rich in layers, have small color difference, good reproducibility, and can achieve the desired effect of design patterns.

[0003] Referring to the Chinese patent application with publication number CN221049326U, a heat transfer film is disclosed, in which moisture-absorbing silica gel particles are bonded inside the protective film, and the bottom of the moisture-absorbing silica gel particles is fixedly connected with a bonding bottom plate. A plurality of gas exchange holes are formed on the surface of the bonding bottom plate. When the outside of the heat transfer film body is in a relatively humid environment, the gas exchange holes are formed on the surface of the protective film close to the heat transfer film body, so that the moisture can be absorbed by the moisture-absorbing silica gel particles inside the protective film through the gas exchange holes. Thus, the heat transfer film body is less affected by moisture, thereby improving the protection of the heat transfer film body. In addition, since the upper surface of the protective film is provided with a glue release pad, the glue release pad can increase the friction force after the heat transfer film body is wound, so that the heat transfer film body will not easily fall off during use.

[0004] However, the color adhesion of the existing heat transfer film is poor. During daily use, the parts that are frequently contacted or rubbed are prone to pattern peeling or wear, which affects the appearance and quality of the product. Once the pattern peels off or is damaged after heat transfer of the heat transfer film with poor color adhesion, it is difficult to repair. Therefore, even a small amount of damage may require replacement of the entire heat transfer film, increasing the cost and trouble. Therefore, we designed a heat transfer film for improving color adhesion. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0022] Based on this, in order to improve the poor color adhesion of the thermal transfer film in the related art, the parts that are often contacted or rubbed in the daily use process are prone to pattern peeling or wear, which affects the aesthetic degree and quality of the product. Once the pattern peeling or damage occurs after the thermal transfer film with poor color adhesion is transferred, it is difficult to repair. Therefore, even if there is only a little damage, the entire thermal transfer film may need to be replaced, which increases the cost and trouble. The embodiments of the present application provide the following solutions.

[0023] Please refer to Figures 1 to 4The application discloses a heat transfer film with improved color adhesion, which comprises a heat transfer film body 1, an anti-warping assembly 3 and an anti-color-falling structure 2.

[0024] Please refer to Figures 2 to 4 The anti-color-falling structure 2 comprises an adhesion promoting coating 21 and a heat-sensitive coating 22, the adhesion promoting coating 21 is fixedly bonded to the heat transfer film body 1, and the heat-sensitive coating 22 is fixedly bonded to the adhesion promoting coating 21; the anti-warping assembly 3 is used for preventing the corners of the heat transfer film from warping; the anti-color-falling structure 2 is used for improving the color adhesion of the heat transfer film; the anti-color-falling structure 2 further comprises an anti-static coating 23, a wear-resistant coating 24 and a waterproof coating 25, the anti-static coating 23 is fixedly bonded to the heat-sensitive coating 22, the wear-resistant coating 24 is fixedly bonded to the anti-static coating 23, and the waterproof coating 25 is fixedly bonded to the wear-resistant coating 24; a plurality of bonding plates 4 are uniformly arranged on the bottom surface of the anti-static layer, a plurality of silica gel water-absorbing particles 5 are uniformly arranged on the bonding plates 4, a plurality of through holes 6 are uniformly arranged on the anti-static coating 23, one end of the through holes 6 is in abutment with the silica gel water-absorbing particles 5, the heat transfer film body 1 is made of a polyester material, the thicknesses of the anti-static coating 23, the wear-resistant coating 24 and the waterproof coating 25 are 0.2-0.3 mm, the thickness of the heat-sensitive coating 22 is 0.2 mm, and the thickness of the adhesion promoting coating 21 is 0.1 mm.

[0025] When water exists on the heat transfer film, the water on the surface of the heat transfer film can flow into the waterproof coating 25 through the through holes 6 arranged on the waterproof coating 25, and then the flowing water can be absorbed by the silica gel water-absorbing particles 5 in the waterproof coating 25; when the heat transfer film exists in a dark and humid environment, the moisture in the air can be absorbed by the silica gel water-absorbing particles 5 through the through holes 6; when the temperature reaches a specific threshold value of the heat-sensitive coating 22, the heat-sensitive material in the coating begins to soften or melt, and the change of the heat-sensitive coating 22 under high temperature can improve the adhesion between the heat transfer film body 1 and a target surface; when static electricity energy is accumulated on the surface of the heat transfer film body 1, the anti-static coating 23 can release the charges through conductivity, so that the static charges cannot be accumulated on the surface of the film, thereby reducing the adsorption of the heat transfer film body 1 to impurities around; the surface of the wear-resistant coating 24 has a low friction coefficient, the heat energy generated in the friction process is reduced, thereby reducing the wear rate, and the wear and friction between the heat transfer film body 1 and a contact surface are reduced.

[0026] The effects of such an arrangement are that by setting the adhesion-promoting coating 21, the adhesion strength between the thermal transfer film and the target material is enhanced, thereby improving the durability and permanence of the pattern, by setting the waterproof coating 25, additional waterproof function can be provided to prevent moisture from damaging the transferred pattern, improving the performance and application range of the thermal transfer film, by setting the anti-static coating 23, preventing static energy from accumulating on the surface of the thermal transfer film, reducing the adhesion of dust and dirt, keeping the transferred pattern clean, by setting the heat-sensitive coating 22, the thermal transfer film can change state at a specific temperature, enhancing the adhesion or color effect during the thermal transfer process, by setting the wear-resistant coating 24, the wear resistance of the thermal transfer film pattern is improved, and the hardness of the surface is enhanced to resist scratches and wear.

[0027] Referring to Figure 3 The anti-warping assembly 3 comprises an anti-warping edge adhesive strip 31 and a tearable handle 32. The anti-warping edge adhesive strip 31 is attached to the corners of the thermal transfer film body 1, and the tearable handle 32 is fixedly connected to one end of the anti-warping edge adhesive strip 31.

[0028] In this way, when using the thermal transfer film, the user tears off the anti-warping edge adhesive strip 31 attached to the corners of the thermal transfer film body 1 through the tearable handle 32 on the anti-warping edge adhesive strip 31, and then uses the thermal transfer film body 1 to adhere to the target surface.

[0029] The effects of such an arrangement are that by setting the anti-warping edge adhesive strip 31 around the thermal transfer film, the corners of the thermal transfer film will not warp during the winding process of the thermal transfer film body 1, thereby affecting the next use of the thermal transfer film, and by setting the tearable handle 32 on the anti-warping edge adhesive strip 31, it is convenient to tear open the anti-warping edge adhesive strip 31 for use of the thermal transfer film, increasing the convenience of use.

[0030] From the above, the working principle of the present application is as follows:

[0031] In use, the user tears off the anti-warping edge adhesive strip 31 attached to the corners of the thermal transfer film body 1 through the tearable handle 32 on the anti-warping edge adhesive strip 31, and then uses the thermal transfer film body 1 to adhere to the target surface.

[0032] When there is water on the heat transfer film, the water on the surface of the heat transfer film will flow into the waterproof coating 25 through the through hole 6 opened on the waterproof coating 25, and then the flowing water will be absorbed by the silica gel water absorption particles 5 inside the waterproof coating 25. When there is water on the heat transfer film, the moisture in the air will be absorbed by the silica gel water absorption particles 5 through the through hole 6 when it is in a dark and humid environment. When the temperature reaches a certain threshold of the heat-sensitive coating 22, the heat-sensitive material in the coating begins to soften or melt. Due to the change of the heat-sensitive coating 22 at high temperature, the adhesion between the heat transfer film body 1 and the target surface is improved. When static electricity energy accumulates on the surface of the heat transfer film body 1, the anti-static coating 23 can release these charges through conductivity, so that static charges will not accumulate on the surface of the film, thereby reducing the adsorption of the heat transfer film body 1 to the surrounding impurities. The surface of the wear-resistant coating 24 has a low friction coefficient, which reduces the generation of heat energy during friction, thereby reducing the wear rate, and the wear and friction between the heat transfer film body 1 and the contact surface will be reduced.

[0033] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
