Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a multifunctional printed material that is easy to display flexibly. Background Technology

[0002] In the field of traditional printing, printed materials such as paper and rigid plastics often suffer from poor flexibility and limited functionality. Traditional paper printed materials are prone to creases and damage during bending and folding, making it difficult to meet the needs of flexible displays, and they also lack special functions such as fire resistance and abrasion resistance. While rigid plastic printed materials have a certain strength, they cannot achieve flexible shape changes such as curling, thus limiting their display formats.

[0003] With technological advancements, some flexographic printed materials utilize a single flexible material, but their overall performance in terms of flexibility, functionality, and durability is unsatisfactory. For example, some flexographic printed materials only improve material selection, lacking effective structural design, making them prone to damage to internal printed patterns during frequent bending. Some smart printed materials integrating chips suffer from poor compatibility between chip packaging and flexible materials, leading to chip detachment or failure, thus failing to meet the needs of practical applications. Furthermore, existing printed materials often employ conventional cutting methods for edge structure design, resulting in tearing and deformation issues during flexible display. Therefore, there is an urgent need for a type of printed material that combines excellent flexible display performance with multifunctional characteristics to meet the market's demand for diverse, high-performance printed materials.

Combined with the deformable toothed structure on the edge, the flexible connection part is made of elastic rubber material, which allows the printed matter to be rolled and bent freely, meeting the flexible display needs in different scenarios, and is not easy to tear or break during deformation. The serpentine reinforcing fiber mesh set between the flexible substrate layer and the elastic buffer layer further enhances the overall flexibility and tensile strength of the printed matter, ensuring that it can still maintain a good shape after multiple bends.

[0022] (2) In terms of functional integration, the surface functional layer is composed of refractory coating and quartz sand, giving printed materials such as stamps fireproof and wear-resistant properties; the internally embedded flexible NFC chip adopts an island-bridge structure packaging, so that the hard chip part is connected through the flexible bridge part, which not only adapts to the flexible deformation of printed materials, but also realizes fast and stable data interaction with smart devices. When users scan printed materials with NFC-enabled devices, they can quickly read the diverse information such as pictures, videos, and URLs pre-stored in the chip, and can also write new data into the chip to complete information update storage as needed, realizing personalized information management of "one item, one code". In addition, the information encryption characteristics of the NFC chip ensure data security and prevent information leakage or tampering.

[0033] I. Preparation of each layer of the printed matter

[0034] ① Flexible substrate layer 11: A 50μm thick polyimide film is selected. Polyimide film has excellent flexibility, high temperature resistance, and chemical stability. The polyimide film is cut into the required printing size through a cutting process.

[0035] ② Image Printing Layer 12: Flexographic printing technology is used to print the designed graphics and patterns onto the upper surface of the flexible substrate layer 11. Environmentally friendly flexographic inks are selected to ensure clear patterns, vibrant colors, and good adhesion to the polyimide film.

[0036] ③ Elastic buffer layer 13: A 100μm thick polyurethane elastomer material is selected and uniformly coated onto the image printing layer 12 using a coating process. The polyurethane elastomer has good elasticity and buffering properties, which can effectively protect the image printing layer from damage during bending and folding.

[0037] ④ Surface functional layer 14: The refractory coating and quartz sand are mixed evenly at a mass ratio of 3:1, and a composite layer is formed on the surface of the elastic buffer layer 13 using a scraping process. The refractory coating is an intumescent fire-retardant coating, and the quartz sand has a particle size of 50-100 mesh, so that the surface functional layer 14 has both fire-retardant and wear-resistant properties. Foldable grooves 141 are made on the surface functional layer 14 using a laser engraving process, and the groove depth is controlled to be 1 / 2 of the thickness of the surface functional layer.

[0038] ⑤ Self-healing protective film layer 5: A self-healing film containing thermo-responsive microparticles 51 is prepared. The thermo-responsive microparticles are selected from cholesteric liquid crystal materials and are uniformly dispersed in a polyurethane matrix through a co-extrusion process to form a film with a thickness of 30 μm. Micron-level uneven texture 52 is pressed onto the surface of the film using an embossing process. The uneven texture is honeycomb-shaped and has a height of 5-10 μm.
