Description

Technical Field

[0001] This utility model relates to the field of inkjet printing film technology, specifically to an ink-absorbing inkjet printing film. Background Technology

[0002] Inkjet film is used as a carrier for advertising patterns. Patterns are drawn on the inkjet film using a printer and then affixed to the desired location for display. It is a flexible film material with advantages such as high-quality printing effects, strong weather resistance, and wide applicability. However, existing inkjet films have simple structures, mostly single-layer structures, which are insufficient in durability, anti-smudging ability, and weather resistance, thus affecting the quality and durability of the inkjet images. In addition, the toughness is poor, resulting in poor tear resistance and tensile strength of the film. This may lead to damage or deformation of the film during transportation, installation, and use, affecting the use effect of the inkjet film. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: an ink-absorbing inkjet printing film.

[0004] Includes: PVC structural base layer, a pair of toughening layers, anti-smudging layer, ink-absorbing layer, pattern layer, weather-resistant coating, and a pair of protective layers;

[0005] A pair of the aforementioned toughening layers are disposed on the upper and lower walls of the PVC structural base layer;

[0006] The anti-smudging layer is disposed on the upper wall surface of the upper toughness layer;

[0007] The ink-absorbing layer is disposed on the upper wall surface of the anti-smudging layer;

[0008] The pattern layer is disposed on the outer wall surface of the pattern layer;

[0009] The weather-resistant coating is applied to the upper wall surface of the pattern layer;

[0010] A pair of protective layers are respectively disposed on the upper wall surface of the pattern layer and below the lower toughness layer.

[0011] Preferably, one or more of the toughening layers is a polyurethane (PU) film.

[0012] Preferably, the pair of the toughening layers are bonded to the upper and lower walls of the PVC structural base layer by an adhesive.

[0013] Preferably, the ink-absorbing layer is a microporous inkjet printing layer.

[0014] Preferably, the weather-resistant coating contains acrylate powder.

[0015] Preferably, the outer wall surface of the pair of protective layers is coated with a hydrophobic coating.

[0016] Beneficial effects

[0017] This invention provides an ink-absorbing inkjet printing film with the following beneficial effects: This solution employs a multi-layer composite structure, assembling the printing film through multi-functional layer lamination. The addition of a toughening layer significantly enhances the film's tear resistance, tensile strength, and impact resistance, making the film more durable and less prone to damage during transportation, installation, and use. Simultaneously, it enhances the film's coating reinforcement effect, ensuring the final image quality and lifespan. This solves the problem of existing inkjet printing films having simple structures, mostly single-layered, resulting in insufficient durability, smudging resistance, and weather resistance, thus affecting the quality and durability of the printed image. Furthermore, their poor toughness leads to poor tear and tensile strength, potentially causing damage or deformation during transportation, installation, and use, thus affecting the printing film's performance.

[0023] Includes: 1. PVC structural base layer, 2. a pair of toughening layers, 3. anti-smudging layer, 4. ink-absorbing layer, 5. pattern layer, 6. weather-resistant coating, and 7. a pair of protective layers;

[0024] A pair of the toughening layers 2 are disposed on the upper and lower walls of the PVC structural base layer 1;

[0025] The anti-smudging layer 3 is disposed on the upper wall surface of the upper toughness layer 2;

[0030] It should be noted that the PVC structural base layer 1 and the toughness layer 2 are integrally molded to form the main structure of the film. The toughness layer 2 is used to increase the overall strength of the film and ensure the tear resistance and tensile strength of the inkjet film. The anti-smudging layer 3 is set below the ink absorption layer 4. The ink absorption layer 4 works with the pattern layer 5 to adsorb and fix the imaging paint to form images or text. The anti-smudging layer 3 below assists in increasing the fixing effect of the paint, preventing ink smudging, and ensuring clear inkjet imaging. The weather-resistant coating 6 is located on the surface of the pattern layer 5 and is used to protect the inkjet image from damage caused by environmental factors such as ultraviolet rays and moisture. It has excellent weather resistance, anti-aging and waterproof performance to ensure the long-term preservation of the inkjet image. The protective layer 7 is used to further protect the inkjet image and improve the durability of the film, increase the wear resistance and scratch resistance of the film, and protect the surface of the film.
