Description

Technical Field

[0001] The utility model relates to the technical field of decorative films, in particular to a sterilization decorative film. Background Art

[0002] Nowadays, decorative films are often applied to the surfaces of furniture, electrical appliances, and other items that people come into contact with daily, providing both protection and aesthetics. However, bacteria and viruses are ubiquitous in our daily lives and work. If these decorative films, which we often come into contact with, could also have a bactericidal effect, they would be extremely beneficial to improving people's health and quality of life.

[0003] For example, Chinese patent publication number CN 202826938 U discloses a bactericidal decorative film comprising a PVC plastic layer bonded to a substrate and a bactericidal material layer bonded to the PVC plastic layer via an adhesive layer. However, the bactericidal decorative film of this technical solution requires further improvement due to the poor environmental performance and aging resistance of the PVC film layer. Therefore, it is necessary to provide a new bactericidal decorative film to address these technical issues. Utility Model Content

[0004] In order to solve at least one of the above-mentioned technical problems, the purpose of the present invention is to provide a sterilization decorative film that is more environmentally friendly and has better aging resistance.

[0005] Based on the above problems, the technical solution provided by the present invention is:

[0006] The utility model aims to provide a bactericidal decorative film, comprising a substrate layer, wherein the substrate layer is a fluorocarbon PET film or a POD film, and a bactericidal material layer is combined on one surface of the substrate layer in the thickness direction by coating or spraying.

[0007] Optionally, the substrate layer and the sterilization material layer are bonded together via an adhesive layer.

[0008] Optionally, the bonding layer is a nano water-based adhesive.

[0009] Optionally, the adhesive layer is bonded to the side of the substrate layer facing the sterilization material layer by coating or spraying.

[0012] Optionally, the sterilization material layer is formed by mixing and extruding PET plastic and sterilization material, and the sterilization material layer is combined with the base material layer by lamination.

[0013] Optionally, the sterilization material layer is formed by mixing fluorocarbon resin and powdered sterilization material, and the sterilization material layer is combined on the substrate layer by coating or spraying.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] This new antibacterial decorative film utilizes fluorocarbon PDF and POD films as the substrate layer, replacing the PVC plastic layer used in prior art. This significantly improves the product's aging resistance, reduces costs, and makes the material more environmentally friendly. The thinner structural layer meets current lightweighting requirements while also lowering costs. A concave-convex or roughened surface is incorporated into the substrate layer on the side that contacts the adhesive layer, enhancing the bonding strength between the two layers.

[0020] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0021] The bactericidal decorative film of the utility model embodiment is shown in FIG. Figure 1 , including a substrate layer 10 and a surface provided on one of the substrate layers 10, namely Figure 1 Above and from the inside out, that is, Figure 1As shown, the adhesive layer 30, pearlescent powder layer 40, and sterilizing material layer 20 are arranged sequentially from bottom to top. In this embodiment of the present invention, the substrate layer 10 is a fluorocarbon PET film or POD film. The thickness of the substrate layer 10 is not limited and can be selected from 0.2-1.0 mm. The adhesive layer 30 is disposed on the surface of the substrate layer 10 facing the sterilizing material layer 20, and the pearlescent powder layer 40 is disposed on the surface of the adhesive layer 30 facing the sterilizing material layer 20. As an alternative embodiment, the sterilizing decorative film of this embodiment of the present invention includes a substrate layer 10 and a sterilizing material layer 20. The substrate layer 10 can also be a fluorocarbon PDF film or POD film. The sterilizing material layer 20 is formed by extruding a mixture of PET plastic and sterilizing material into a film layer. The sterilizing material layer 20 is then bonded to the upper surface of the substrate layer 10 using a conventional laminating device, resulting in a thinner thickness and lower cost. As another alternative embodiment, the pearlescent powder layer 40 is not disposed between the adhesive layer 30 and the sterilizing material layer 20.

[0022] Regarding the substrate layer 10, in an embodiment of the present invention, in one optional embodiment, the substrate layer 10 is a conventional fluorocarbon PET film currently available on the market, also known as a PET-based fluorocarbon film. In another optional embodiment, the substrate layer 10 is a conventional POD film currently available on the market. Fluorocarbon PET film is a film made by coating a fluorocarbon resin on the surface of polyethylene terephthalate (PET) using polyethylene terephthalate (PET) as a substrate. Fluorocarbon resin has excellent weather resistance, chemical resistance, and self-cleaning properties, and is widely used in fields such as long-term corrosion protection of steel structures, marine corrosion protection, exterior building decoration, and solar cell backplanes. In summary, the fluorocarbon PET film used in the present invention has weather resistance and aging resistance. Automobile exterior steel plates are often exposed to sunlight, and the decorative films thereon are also often exposed to sunlight. This can improve the steel plates' UV resistance and aging resistance, thereby extending the product's service life. As for POD membrane, POD (polyoxadiazole) membrane refers to a special porous, breathable membrane material made from ultra-high molecular weight polyethylene powder through a special process. This membrane is breathable and has a low friction coefficient, while maintaining the chemical resistance, wear resistance, and anti-stickiness properties of ultra-high molecular weight polyethylene. This membrane is widely used in semiconductor manufacturing equipment, for example, playing a key protective role in sensors. Furthermore, POD membrane is cheaper than commercially available PVC and PET films (according to the current market price of PVC is approximately 5,436.00 yuan / ton, PP is approximately 5,426.00 yuan / ton, and POD is approximately 5,080.00 yuan / ton), which can reduce costs.

[0023] For the sterilization material layer 20, the existing conventional sterilization materials such as inorganic sterilization paint (silver, zinc and the like), organic antibacterial material, natural antibacterial material such as some minerals or composite antibacterial material and the like can be selected to be blended with PET plastic, then co-extrusion molding is performed to form a film or the sterilization material is supported in powder form, then mixed uniformly with fluorocarbon resin paint, and then combined on the substrate layer 10 by coating or spraying. Details are not particularly described and limited.

[0024] For the bonding layer 30, the existing conventional nano water-based adhesive on the market is preferred in the embodiment of the present application. The nano water-based adhesive has high temperature resistance, does not cause corrosion to the object, is firmly combined, is not easy to fall off even if exposed to the sun, and is more environmentally friendly compared with other adhesives. The thickness of the bonding layer 30 is not particularly limited and described. The person skilled in the art can select and design according to the actual scene or the required amount of nano adhesive. In a preferred embodiment of the present application, the substrate layer 10 and the sterilization material layer 20 are combined together through the bonding layer. The substrate layer 10 and the sterilization material layer 20 can also be directly combined together by pressing.

[0025] In a preferred embodiment of the present application, some rough structures or concave-convex structures are provided on the side of the bonding layer 30 facing the sterilization material layer 20. For example, the surface of the substrate layer 10 can be made rough and uneven by sandblasting or some concave stripes are formed on the surface of the substrate layer 10, so as to improve the bonding strength of the bonding layer 30 and the substrate layer 10.

[0026] In summary, compared with the sterilization decorative film in the background art, the sterilization decorative film in the embodiment of the present application uses fluorocarbon PDF film and POD film instead of PVC film in the background art. The aging resistance of the product is greatly improved and the cost is reduced. The material is more environmentally friendly. The structure layer is thinner, meets the existing lightweight requirements, and has lower cost. The side of the substrate layer 10 contacting the bonding layer 30 is provided with concave-convex structures (not shown) or rough structures (not shown), so as to improve the bonding strength of the substrate layer 10 and the bonding layer 30.

[0027] In addition, it should be noted that, Figure 1 The thickness of each layer shown in the above-mentioned embodiment does not represent the actual thickness.

[0028] The above examples are only for illustrating the technical concept and characteristics of the present application. The purpose is to enable those skilled in the art to understand the content of the present application and to implement it. It cannot limit the protection scope of the present application. Any equivalent transformation or modification made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
