Description

Technical Field

[0001] This utility model relates to the field of transfer paper technology, and in particular to a tear-resistant heat sublimation transfer paper. Background Technology

[0002] Existing tear-resistant sublimation transfer paper is a special type of paper used in the sublimation transfer process, mainly for transferring various patterns, texts, or images onto different substrates.

[0003] However, it has low strength and is easily torn when subjected to external force during handling, printing, or transfer, which reduces the durability of the transfer paper, increases the cost of use and time, and has poor moisture resistance. In humid environments, moisture can easily penetrate the paper, leading to a decrease in paper strength. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a tear-resistant sublimation transfer paper. Through the surface layer of polyester fiber, which has excellent adsorption properties for sublimation ink, the pattern carried by the ink can be accurately transferred to the substrate. The reinforcing layer one, made of aramid fiber, significantly enhances the overall tear resistance, effectively resisting external pulling forces during the transfer process and greatly reducing the risk of paper tearing. The reinforcing layer two, made of glass fiber, further improves the tear resistance of the transfer paper, allowing it to maintain good integrity even when facing various complex external forces. The moisture-proof layer, made of nano-silica coating, effectively blocks the intrusion of external moisture, ensuring the transfer paper remains intact even in humid environments during storage or use. It also avoids the decrease in strength caused by moisture. The polymer heat-stabilizing layer filled with mica powder can effectively maintain the shape stability of the paper during high-temperature transfer, preventing the paper from shrinking or deforming due to excessive temperature. The polyurethane elastomer flexibility enhancement layer gives the transfer paper better bending and folding performance. During the transfer process, it can adapt to the substrate of various shapes and fit tightly to its surface, reducing the risk of loose adhesion or tearing caused by excessive paper rigidity. The polytetrafluoroethylene film isolation layer can effectively prevent ink and other substances from penetrating, which ensures that the ink of the heat transfer layer will not be contaminated. The kraft paper base layer can bear the weight of other functional layers and maintain the overall structural stability of the paper during the processing, handling and use of the transfer paper.

[0005] This utility model also provides a tear-resistant sublimation transfer paper, comprising: a transfer paper body, wherein the transfer paper body is composed of a surface layer, a first reinforcing layer, a second reinforcing layer, a moisture-proof layer, a heat-stabilizing layer, a flexibility-enhancing layer, an isolation layer, and a base layer; the first reinforcing layer is fixedly connected to the lower surface of the surface layer; the second reinforcing layer is fixedly connected to the lower surface of the first reinforcing layer; the moisture-proof layer is fixedly connected to the lower surface of the second reinforcing layer; the heat-stabilizing layer is fixedly connected to the lower surface of the moisture-proof layer; the flexibility-enhancing layer is fixedly connected to the lower surface of the heat-stabilizing layer; the isolation layer is fixedly connected to the lower surface of the flexibility-enhancing layer; the base layer is fixedly connected to the lower surface of the isolation layer; and a supporting frame is fixedly connected to the outer surface of the transfer paper body.

[0006] According to the present invention, a tear-resistant sublimation transfer paper is provided, wherein the surface material is polyester fiber.

[0007] According to the present invention, the material of the first reinforcing layer is aramid fiber.

[0008] According to the present invention, the material of the second reinforcing layer is glass fiber.

[0009] According to the present invention, a tear-resistant sublimation transfer paper is provided, wherein the moisture-proof layer is made of nano-silica coating.

[0010] According to the present invention, a tear-resistant sublimation transfer paper is provided, wherein the heat-stabilizing layer is a polymer filled with mica powder.

[0011] According to the present invention, the material of the flexible reinforcement layer of the tear-resistant heat sublimation transfer paper is polyurethane elastomer.

[0012] According to the present invention, a tear-resistant heat sublimation transfer paper is provided, wherein the isolation layer is made of polytetrafluoroethylene film and the base layer is made of kraft paper.

[0013] Compared to existing technologies, this tear-resistant sublimation transfer paper utilizes a polyester fiber surface layer. Polyester fibers have excellent adsorption properties for sublimation ink, allowing for precise transfer of the ink-carried pattern onto the substrate. A reinforcing layer one made of aramid fiber significantly enhances overall tear resistance, effectively resisting external pulling forces during the transfer process and greatly reducing the risk of tearing. A second reinforcing layer made of glass fiber further improves the tear resistance, ensuring the transfer paper maintains its integrity even under various complex external forces. Finally, a moisture-proof layer made of nano-silica coating effectively prevents the intrusion of external moisture, preventing damage from damp environments during storage or use. Despite the reduced strength, the polymer heat-stabilizing layer filled with mica powder effectively maintains the shape stability of the paper during high-temperature transfer, preventing shrinkage and deformation due to excessive temperature. The polyurethane elastomer flexibility enhancement layer gives the transfer paper better bending and folding properties, allowing it to adapt to various shapes of substrates during the transfer process and adhere closely to their surfaces, reducing the risk of loose adhesion or tearing caused by excessive paper rigidity. The polytetrafluoroethylene film isolation layer effectively prevents ink and other substances from penetrating, ensuring that the ink in the heat transfer layer is not contaminated. The kraft paper base layer can support the weight of other functional layers, maintaining the overall structural stability of the paper during processing, handling, and use.
