[0001] This invention relates to the field of thin-layer plastics technology, and in particular to a luminescent antibacterial and dust-adhesive product and its preparation method. Background Technology
[0002] Dust removal products on the market are often limited in function and primarily focus on physical dust collection. For example, traditional dust collection pads and adhesive films, after capturing dust and dirt, can easily become breeding grounds for bacteria and mites, especially in humid environments, potentially causing secondary pollution. Alternatively, they lack additional features and fail to meet users' higher demands for health, safety, and convenience. Furthermore, conventional dust removal products have low visibility in dimly lit environments, affecting ease of use and safety. Summary of the Invention
[0003] The main objective of this invention is to develop a product that combines antibacterial, mite-removing, and luminous functions. This product comes in various forms, including but not limited to dust removal rollers and sticky mats, and can be used for dust removal, mite removal, and antibacterial purposes in various scenarios and for various objects.
[0004] To achieve the above objectives, the present invention proposes a luminescent antibacterial adhesive product, wherein the luminescent antibacterial adhesive product includes at least one tearable unit; the tearable unit includes a base film layer, a luminescent layer and an adhesive layer stacked sequentially from top to bottom; wherein the luminescent layer includes a luminescent ink layer or a luminescent powder layer.
[0005] In one embodiment, the luminous antibacterial adhesive product includes a luminous antibacterial adhesive mat, which comprises a plurality of tearable units stacked together; or, the luminous antibacterial adhesive product includes a luminous antibacterial adhesive roller, which comprises a plurality of tearable units wound together.
[0006] In one embodiment, the ink used to prepare the luminescent ink layer comprises the following raw materials in weight percentages: UV transparent varnish: 58.4wt%~99wt%; luminescent powder: 0.2wt%~40wt%; antibacterial agent: 0.2wt%~0.6wt%; dispersant: 0.4wt%~0.8wt%.

[0009] In one embodiment, the base film layer is selected from any one of polylactic acid film, polybutylene succinate film, polyhydroxybutyrate film, polyethylene film, polypropylene film, and OPP film.
[0010] In one embodiment, the adhesive used to prepare the adhesive layer comprises the following raw materials in weight percentages: acrylic pressure-sensitive adhesive: 98.8wt%~99.2wt%; antibacterial agent: 0.4wt%~0.6wt%; acaricide: 0.4wt%~0.6wt%; wherein the acaricide comprises 0.2wt%~35wt% p-chloro-m-xylenol and 0.2wt%~30wt% sodium hydroxide.
[0011] In one embodiment, the tearable unit includes a first base film layer, a luminescent layer, a second base film layer, and an adhesive layer stacked sequentially from top to bottom.

[0013] The present invention also proposes a method for preparing the aforementioned luminescent antibacterial and dust-adhesive product, comprising the following steps: S10. Perform corona treatment on the base film layer and set aside for later use; S20. Prepare luminescent ink, sieve it, screen print it onto the surface of the base film layer in step S10, and cure it to form a luminescent ink layer. S30. Prepare an adhesive, apply it to the surface of the luminescent ink layer in step S20, dry it to form an adhesive layer, roll it, cure it to obtain an intermediate, and then wind and cut it to obtain the luminescent antibacterial adhesive product.
[0014] The present invention also proposes another method for preparing the aforementioned luminescent antibacterial and dust-adhesive product, comprising the following steps: S10. The base film layer is subjected to constant temperature baking treatment until the base film layer softens; S20. The softened base film layer is uniformly coated with phosphorescent powder to form a phosphorescent layer. S21. Lay another base film layer on the surface of the luminescent layer and roll it; S30. Prepare an adhesive, apply it to the surface of the other base film layer after rolling in step S21, dry it to form an adhesive layer, roll it, cure it to obtain an intermediate, and then wind and cut it to obtain the luminous antibacterial dust-adhesive product.
[0015] The technical solution of this invention designs a luminescent antibacterial dust-adhesive product. Through the composite structure design of the base film layer, the luminescent layer and the adhesive layer, combined with the synergistic effect of antibacterial agents and luminescent materials, it achieves efficient dust adhesion while also having luminescent visibility and antibacterial and anti-mite functions. It has the advantages of effectively solving the problems of easy bacterial growth, low nighttime visibility and secondary pollution of traditional products. Detailed Implementation
[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0017] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0018] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0019] The technical problem addressed by this application is that, in existing technologies, traditional dust removal products mainly rely on physical adhesion to capture dust, but microorganisms easily accumulate on the surface after use, which may cause secondary pollution, especially in humid environments. Such products also have insufficient visibility in low-light environments, affecting user positioning and operational safety; for example, it is difficult to quickly identify dust removal areas at night or in poorly lit indoor environments.
[0020] To address the aforementioned technical challenges, the research and development process revealed that single-function designs could not meet modern cleaning needs, requiring simultaneous solutions to microbial growth and low-light environment performance. By analyzing the possibilities of material function integration, the feasibility of integrating optical properties and antibacterial performance into the dust-adhesive structure was explored, ultimately leading to a design concept of separable functional units.
[0021] Therefore, this application proposes a luminescent antibacterial adhesive product, including at least one tearable unit, which comprises a base film layer, a luminescent layer and an adhesive layer stacked sequentially from top to bottom.
[0022] The tearable unit refers to a functional unit that can be independently peeled off. This can be achieved through a slitting process to create weak interlayer adhesion, facilitating layer-by-layer replacement. The base film layer is the substrate material that supports the functional coating. It can be made using a biodegradable polymer film, providing structural support and surface smoothness. The luminescent layer is a functional layer with light-gathering properties. It can be achieved through luminescent ink printing or luminescent powder coating, absorbing and storing energy from external light sources to achieve self-luminescence. The adhesive layer is a gel-like layer with adhesive properties. It can be made using pressure-sensitive adhesive with added antibacterial components, adhering to dust while inhibiting microbial growth.
[0023] Specifically, the base film layer acts as a supporting carrier, bearing the optical function of the luminescent layer. The luminescent layer releases visible light in dark environments through light-gathering substances, enhancing product visibility. The adhesive layer, in addition to its conventional dust-adhesive function, inhibits the growth of bacteria and mites by adding antibacterial agents to disrupt the structure of microbial cells. Once the surface adhesive layer is saturated, the old unit can be peeled off along the interlayer separation interface, activating the underlying cleaning unit.
[0024] Compared with existing technologies, traditional products use a single dust-adhesive layer structure and lack active antibacterial mechanisms and optical auxiliary functions. In contrast, this solution achieves dust adhesion, antibacterial and luminous functions simultaneously through a multi-layer composite structure, which expands environmental adaptability and hygiene safety while maintaining basic cleaning performance.
[0025] Through the above technical solutions, this application effectively reduces the risk of secondary microbial contamination during the cleaning process, improves product visibility and ease of operation in low-light environments, and extends the effective service life of cleaning tools.
[0026] This application further proposes a luminous antibacterial adhesive dust product including a luminous antibacterial adhesive dust mat, the luminous antibacterial adhesive dust mat including a plurality of tearable units stacked together; or a luminous antibacterial adhesive dust product including a luminous antibacterial adhesive roller, the luminous antibacterial adhesive roller including a plurality of tearable units wound together.
[0027] Among them, the luminous antibacterial adhesive mat refers to a planar structure formed by multiple tearable units stacked together, specifically using polypropylene film as the substrate. The stacked structure allows for layer-by-layer peeling and replacement, preventing overall failure due to single-layer contamination. The luminous antibacterial adhesive roller refers to a cylindrical structure formed by multiple tearable units wound together, specifically using polyethylene film as the substrate. The wound structure allows for continuous peeling and use, reducing frequent replacement operations. The stacking configuration refers to multiple tearable units stacked vertically, specifically fixed by heat pressing or adhesive bonding, ensuring each layer remains independently peelable, guaranteeing that only the surface layer needs to be removed after contamination. The winding configuration refers to multiple tearable units spirally wound around a central axis, specifically formed into a continuous roll through a roller pressing process, utilizing a rotational peeling mechanism to automatically replace the cleaning surface.
[0028] Specifically, the luminous antibacterial adhesive mat uses multiple tearable units stacked together, allowing the surface layer to be quickly removed after becoming soiled, while the uncontaminated adhesive layer underneath continues to function, extending the product's lifespan. For example, when laying this mat at the entrance of a public place, the surface layer can be directly peeled off after absorbing dust, eliminating the need for complete replacement. The luminous antibacterial adhesive roller uses multiple tearable units wound together, rotating during cleaning to cover the surface with a new adhesive layer. For example, when cleaning walls, the roller automatically exposes the unused layer after rolling, reducing manual intervention. Both structures address the frequent replacement issues of traditional single-layer products through multi-unit design, while the luminous layer enhances visibility in low-light environments.
[0029] This application further proposes that the ink used to prepare the luminescent ink layer comprises the following raw materials in weight percentages: 58.4wt%~99wt% UV transparent varnish; 0.2wt%~40wt% luminescent powder; 0.2wt%~0.6wt% antibacterial agent; and 0.4wt%~0.8wt% dispersant. The UV transparent varnish refers to a transparent resin matrix with ultraviolet curing properties, specifically achieved using a mixture of acrylate prepolymers and photoinitiators. Its function is to provide a carrier matrix for the luminescent powder and form a transparent protective layer. The luminescent powder refers to inorganic or organic materials that store and emit light upon exposure to light, specifically achieved using a rare-earth-doped aluminate system. Its function is to continuously release the stored light energy in a dark environment. The antibacterial agent refers to compounds that can inhibit microbial growth, specifically achieved using quaternary ammonium salts or nano-silver. Its function is to reduce the risk of bacterial growth by disrupting the microbial cell membrane structure.
[0030] It should be noted that when the tearable unit of the luminescent antibacterial adhesive product in this application consists of only three layers stacked from top to bottom: a base film layer, a luminescent layer, and an adhesive layer, the luminescent layer can only be a luminescent ink layer.
[0031] In one specific embodiment, the thickness of the luminescent ink layer is 10μm to 200μm. Optionally, the thickness of the luminescent ink layer can be 10μm, 20μm, 50μm, 100μm, or 200μm, and any thickness within the above range is acceptable. By limiting the thickness of the luminescent ink layer, the luminescence brightness of the luminescent ink layer in the tearable unit is further ensured, allowing it to emit higher brightness and a longer afterglow time while being thinner and lighter.
[0032] This application further proposes that in the luminescent antibacterial dust-adhesive product, the luminescent powder includes long afterglow type luminescent powder, and the particle size of the luminescent powder is 200 mesh to 800 mesh; and / or, the antibacterial agent includes nano silver.
[0033] Long-afterglow luminescent powder refers to a luminescent material that can emit light continuously for more than one hour after being excited by a light source. It can be achieved using rare-earth doped materials with aluminate or silicate matrices, such as the SrAl2O4:Eu,Dy system. This material releases energy slowly through electron traps formed by crystal defects, thus maintaining visibility in dark environments. Luminescent powder with a particle size of 200-800 mesh refers to powder with a particle size distribution within this range. This can be controlled through mechanical grinding and grading processes, such as using an air jet mill to process the raw powder. This particle size range ensures the fluidity of the ink during printing while avoiding attenuation of luminescence intensity due to excessively fine particles. Nano-silver refers to elemental silver particles with a particle size in the range of 1-100 nm, which can be prepared using chemical reduction or physical vapor deposition methods. Nano-silver achieves broad-spectrum antibacterial effects by releasing silver ions to disrupt the cell membrane structure of microorganisms.
[0034] Specifically, long-afterglow luminescent powder is uniformly dispersed in UV transparent varnish to form a luminescent ink layer. When ambient light levels decrease, this material continuously releases visible light through stored light energy, ensuring the clear visibility of the mat's edge outline in low-light areas such as corridors or stairwells. The luminescent powder particle size is controlled within the range of 200-800 mesh to avoid particle agglomeration affecting ink printing uniformity while ensuring the effective number of luminescent particles per unit area. Nano-silver is dispersed in the adhesive, inhibiting the growth of microorganisms in adhered contaminants through contact sterilization; for example, the growth of Staphylococcus aureus and Escherichia coli is effectively blocked.
[0035] In one embodiment, the base film layer is selected from any one of polylactic acid film, polybutylene succinate film, polyhydroxybutyrate film, polyethylene film, polypropylene film, and OPP film.
[0036] In one embodiment, the thickness of the base film layer is 0.02 mm to 1 mm. Optionally, the thickness of the base film layer can be 0.02 mm, 0.03 mm, 0.1 mm, 0.5 mm, 1 mm, etc., and any thickness within the above range is acceptable.
[0037] This application further proposes that the adhesive used to prepare the bonding layer comprises the following raw materials in weight percentages: acrylic pressure-sensitive adhesive 98.8wt%~99.2wt%; antibacterial agent 0.4wt%~0.6wt%; acaricide 0.4wt%~0.6wt%; wherein the acaricide comprises 0.2wt%~35wt% p-chloro-m-xylenol and 0.2wt%~30wt% sodium hydroxide.
[0038] Acrylic pressure-sensitive adhesives are pressure-sensitive adhesives with acrylate monomers as the main component. They are specifically prepared using emulsion polymerization processes and possess high initial tack and holding power, forming a uniform adhesive layer on the substrate surface. Specifically, the adhesive uses acrylic pressure-sensitive adhesive as the base bonding material, combined with a specific ratio of antibacterial agents and composite acaricides to form an adhesive layer with continuous antibacterial and acaricide functions. During the adhesive coating process, the acrylic pressure-sensitive adhesive provides stable bonding performance, while nano-silver particles are uniformly dispersed in the adhesive layer to form an antibacterial network. The synergistic effect of chloro-m-xylenol and sodium hydroxide ensures that the acaricide active ingredients remain effective within the adhesive layer for a long period. When this adhesive is applied to dust-collecting products, it not only captures dust particles but also releases antibacterial and acaricide components upon contact, blocking the reproduction pathways of microorganisms on the adhesive layer surface.
[0039] In one embodiment, the thickness of the adhesive layer is 10 μm to 200 μm; optionally, the thickness of the adhesive layer can be 10 μm, 20 μm, 50 μm, 100 μm, or 200 μm, and any thickness within the above range is acceptable. By further limiting the thickness range of the adhesive layer, the bonding strength of the adhesive layer is further limited, allowing it to be easily torn off from the next tearable unit under manual tearing conditions.
[0040] This application further proposes that the tearable unit includes a first base film layer, a luminescent layer, a second base film layer, and an adhesive layer stacked sequentially from top to bottom.
[0041] Specifically, the first base film layer, as the outermost layer, protects the underlying structure through mechanical strength. The luminescent layer is sandwiched between the two base film layers, preventing direct contact with the external environment or adhesives that could lead to performance degradation. When the second base film layer is combined with the adhesive layer, it prevents adhesive components from back-permeating into the luminescent layer and allows for layer-by-layer peeling and replacement through a tear-away design. When the tear-away unit is used, after dust adheres to the adhesive layer, the second base film layer can be peeled off along with the adhesive layer, while the luminescent layer and the first base film layer remain intact, ensuring that the remaining unused portion continues to glow.
[0042] Through the above technical solution, this application solves the problem that single-layer base film structures are easily affected by adhesive penetration, thus impacting their luminescent performance. Simultaneously, the layered peeling mechanism reduces the risk of contamination in unused portions. The synergistic effect of the double-layer base film enhances the structural stability of the peelable unit, ensuring that the luminescent layer maintains its luminescent function even after multiple peeling operations, thereby continuously improving usability in dim environments.
[0043] In one embodiment, when the tearable unit of the luminescent antibacterial adhesive product in this application comprises a four-layer structure consisting of a first base film layer, a luminescent layer, a second base film layer, and an adhesive layer stacked sequentially from top to bottom, the luminescent layer can be a luminescent ink layer or a luminescent powder layer.
[0044] In one specific embodiment, the amount of luminescent powder in the luminescent powder layer is 0.2wt% to 40wt% of the tearable unit mass.
[0045] This application further proposes that the initial brightness of the luminescent antibacterial and dust-adhesive product should not be less than 280 mcd / m 2 The afterglow time of the luminescent antibacterial and dust-adhesive product is 6-8 hours. Initial brightness refers to the luminous intensity of the luminescent material immediately after the excitation source is stopped. This is achieved by mixing long-afterglow luminescent powder with UV transparent varnish and then forming a uniform coating through screen printing. This parameter ensures sufficient visibility of the product in dim environments. Afterglow time refers to the duration after excitation stops, when the brightness of the luminescent material decays to a level visible to the human eye. This is achieved by controlling the particle size distribution and addition ratio of the luminescent powder. This parameter allows the product to continuously provide illumination guidance even in the absence of an external light source.
[0046] In one embodiment, the present invention further provides a method for preparing the above-mentioned luminescent antibacterial and adhesive dust-repellent product, comprising the following steps: S10. Perform corona treatment on the base film layer and set aside for later use; S20. Prepare luminescent ink, sieve it, screen print it onto the surface of the base film layer in step S10, and cure it to form a luminescent ink layer. S30. Prepare an adhesive, apply it to the surface of the luminescent ink layer in step S20, dry it to form an adhesive layer, roll it, cure it to obtain an intermediate, and then wind and cut it to obtain the luminescent antibacterial adhesive product.
[0047] In another embodiment, the present invention further provides a method for preparing the above-mentioned luminescent antibacterial and dust-adhesive product, comprising the following steps: S10. The base film layer is subjected to constant temperature baking treatment until the base film layer softens; S20. The softened base film layer is uniformly coated with phosphorescent powder to form a phosphorescent layer. S21. Lay another base film layer on the surface of the luminescent layer and roll it; S30. Prepare an adhesive, apply it to the surface of the other base film layer after rolling in step S21, dry it to form an adhesive layer, roll it, cure it to obtain an intermediate, and then wind and cut it to obtain the luminous antibacterial dust-adhesive product.
[0048] The constant-temperature baking process involves softening the base film layer by controlling the temperature. This can be achieved using a hot air circulating oven at 50℃~80℃ for 5~10 minutes. This process increases the surface activity of the base film layer, facilitating the subsequent adhesion of the luminescent powder. Uniform adhesion of the luminescent powder involves dispersing it onto the softened base film surface through mechanical vibration or electrostatic adsorption. This can be achieved using vibrating sieving equipment or electrostatic spraying devices. This method avoids the influence of the ink carrier on the luminescent powder's luminescent properties. Rolling involves applying pressure between two base film layers to enhance interlayer adhesion, allowing the luminescent powder to be embedded onto the substrate film by the pressure rollers. This can be done using rubber or metal rollers at a pressure of 0.2~0.5MPa. This operation eliminates air bubbles and improves the density of the luminescent layer.
[0049] Specifically, after the base film layer is softened by constant-temperature baking, its surface forms a slightly molten state. At this point, the phosphorescent powder is evenly embedded into the surface of the base film layer through vibration or electrostatic action. Subsequently, another base film layer is covered and tightly bonded by roller pressing. After the adhesive is applied to the surface of the outer base film, it is dried to form an adhesive layer with antibacterial and anti-mite functions. Finally, through curing and cutting, a tearable unit structure is obtained.
[0050] Through the above technical solution, this application solves the risk of bacterial growth caused by the introduction of organic matter into traditional adhesive products due to ink carriers, while reducing production costs by simplifying the process. Direct adhesion of the luminescent powder avoids the impact of ink on luminescence efficiency, ensuring high visibility of the product in dim environments. The rolling and curing processes further enhance the durability of the multi-layered structure, ensuring long-term effectiveness of the adhesive function.
[0051] The present invention will be further illustrated below through specific embodiments: The raw materials, reagents, or devices used in the embodiments of this invention are all commercially available.
