Technical Field

[0001] The utility model relates to the technical field of color inkjet lamp sheets, in particular to a structure of a color inkjet lamp sheet with bactericidal and antiviral properties and degradability. Background Art

[0002] With the continuous development of color inkjet technology, color inkjet lamp sheets are increasingly used in the medical field due to their price advantages, such as medical imaging diagnosis, etc. In hospitals and environments where viruses are easily transmitted, traditional lamp sheets are likely to carry viruses as a medium. After being used as a diagnostic basis, they are generally quickly discarded or taken away by patients, resulting in further cross-infection. Moreover, those discarded virus-containing lamp sheets will also cause "white pollution" to the environment, which does not meet the current green environmental protection concept and environmental protection requirements.

[0003] The present utility model is made based on the above situation. Content of the Utility Model

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following further details the specific embodiments of the present utility model with reference to the drawings, wherein:

[0019] Figure 1 is a schematic structural diagram of the present utility model. SPECIFIC EMBODIMENTS

[0020] The following further describes the present utility model with reference to the drawings:

[0021] As Figure 1 shown, a kind of bactericidal and antiviral degradable color inkjet lamp sheet structure includes a degradable and light-transmitting PLA substrate 1, a primer layer 2 is provided on the surface of the PLA substrate 1, a waterproof and light-transmitting color inkjet ink absorption layer 3 is provided on the surface of the primer layer 2, and a bactericidal material layer 4 capable of bactericidal and antiviral is provided on the surface of the color inkjet ink absorption layer 3, which can inhibit or kill microorganisms such as bacteria, viruses, and fungi through this bactericidal material layer 4, reduce the transmission of pathogens, thereby reducing the risk of hospital-acquired infections.

[0022] Specifically, the sterilizing material layer 4 can be a silver ion nano-sterilizing and antiviral coating. The silver ion nano-sterilizing and antiviral coating is generally safe for the human body and will not produce obvious side effects or toxicity. It can kill various types of bacteria, fungi, and viruses, having a wide antibacterial spectrum. It can continuously release silver ions for a long time, thereby providing a lasting antibacterial and antiviral effect. In some cases, it can degrade or decompose into environmentally friendly substances. The silver ion nano-sterilizing and antiviral coating is composed of a silica sol dispersion of nano silver ions, and its color is close to transparent, having good light transmission performance. Of course, it can also be other silver ion nano-sterilizing and antiviral coatings. The silver ion nano-sterilizing and antiviral coating can be quantitatively sprayed by a coater, and the coating weight after drying is 0.3 - 1 g / m².

[0023] In some embodiments, the sterilizing material layer 4 is disposed on the lower surface of the color inkjet absorbing layer 3, the color inkjet absorbing layer 3 is disposed on the lower surface of the primer layer 2, and the primer layer 2 is disposed on the lower surface of the PLA substrate 1.

[0024] The PLA substrate 1 is made of a bio-based starch material, such as corn, beet, sugarcane, etc. Through the process of microbial fermentation, starch is converted into lactic acid, and lactic acid is chemically treated to convert it into lactic acid monomers. Subsequently, these monomers form PLA through a polymerization reaction. Since it is derived from plants, under appropriate conditions, PLA can degrade into water and carbon dioxide. The weight per unit area of the PLA substrate 1 is 80 - 150 g / m².

[0025] In some embodiments, the primer layer 2 includes an aqueous acrylic copolymer primer layer. It can significantly improve the adhesion between the subsequent color inkjet absorbing layer 3 and the substrate. The primer layer 2 can be coated on the PLA substrate 1 by a bridge coater blade coater, and the weight per unit area of the aqueous acrylic copolymer primer coating after drying is 0.5 - 2 g / m².

[0026] In some embodiments, the color inkjet absorbing layer 3 includes a waterproof and high-gloss transparent nano-aluminum glue color inkjet layer. It has excellent waterproof performance and can remain clear even in a humid environment. At the same time, it can also provide a more delicate and smooth surface, which is helpful for the coating of the silver ion nano-sterilizing and antiviral coating. The color inkjet absorbing layer 3 can be coated by a bridge coater with a slot extrusion coating head. After drying by a drying oven, the weight per unit area of the color inkjet absorbing layer 3 is 25 - 30 g / m².
