Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, and in particular to a luminescent antibacterial and dust-adhesive product. 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 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. Utility Model Content

[0003] The main purpose of this utility model is to develop a product that combines antibacterial, mite-removing, and luminous functions. This product has 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] This utility model proposes a luminescent antibacterial dust-adhesive product, which 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.

[0005] In one embodiment, the luminous antibacterial adhesive product includes a luminous antibacterial adhesive mat, which comprises a plurality of tearable units stacked together; in the luminous antibacterial adhesive mat, the adhesive layer is used to contact the soles of the feet.

[0006] In one embodiment, the luminous antibacterial adhesive product includes a luminous antibacterial adhesive roller, which includes a plurality of tearable units wound together; in the luminous antibacterial adhesive roller, the adhesive layer is used to contact the object to be cleaned.

[0007] In one embodiment, the base film layer is selected from any one of polylactic acid film layer, polybutylene succinate film layer, polyhydroxybutyrate film layer, polyethylene film layer, polypropylene film layer, and OPP film layer.

[0008] In one embodiment, the luminescent layer comprises a luminescent ink layer.

[0009] In one embodiment, the thickness of the base film layer is 0.02 mm to 1 mm; and / or, the thickness of the luminescent layer is 10 μm to 200 μm; and / or, the thickness of the adhesive layer is 50 μm to 200 μm.

[0011] In one embodiment, the luminescent layer comprises a luminescent powder layer or a luminescent ink layer.

[0012] In one embodiment, the first base film layer and the second base film layer have the same shape and size.

[0013] This invention relates to a luminescent antibacterial dust-adhesive product. The product comprises multiple peelable units stacked or wound together.

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] It should be noted that if the embodiments of this utility model 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.

[0020] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such 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.

[0021] 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 cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] The technical problem solved by this invention is that, in the prior art, 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 the dust removal area at night or in poorly lit indoor settings.

[0023] 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.

[0024] To solve the above problems, refer to Figure 1 This utility model proposes a luminescent antibacterial dust-adhesive product, including at least one tearable unit 1; the tearable unit 1 includes a base film layer 11, a luminescent layer 12 and an adhesive layer 13 stacked sequentially from top to bottom.

[0025] Among them, the tearable unit 1 refers to a functional unit that can be independently peeled off. The tearable unit 1 can be stacked as a whole or rolled up into a whole. The base film layer 11 refers to the base material that carries the functional coating, which can be implemented using a biodegradable polymer film. The luminescent layer 12 refers to a functional layer with light-emitting properties, which can be implemented by printing and curing luminescent ink or coating with luminescent powder. The adhesive layer 13 refers to an adhesive layer with adhesive properties, which can be implemented using a pressure-sensitive adhesive compounded with antibacterial and anti-mite components, which can inhibit the growth of microorganisms while adhering to dust.

[0026] Specifically, the base film layer 11 serves as a supporting carrier for the optical function of the luminescent layer 12, which releases visible light in dark environments through light-gathering materials, enhancing product visibility. The adhesive layer 13, 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 tearable units can be peeled off along the interlayer separation interface, activating the new tearable units on the lower layer.

[0027] 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.

[0028] In one embodiment, this application further proposes a luminous antibacterial adhesive mat, which includes a plurality of tearable units 1 stacked together; in the luminous antibacterial adhesive mat, the adhesive layer 13 is used to contact the soles of the feet.

[0029] It should be noted that the layered setup refers to multiple tearable units 1 being stacked sequentially in the vertical direction. Specifically, they can be fixed by hot pressing or adhesive, so that each layer remains independent and peelable, ensuring that only the surface layer needs to be removed after contamination.

[0030] The luminescent antibacterial dust-adhesive mat is a planar structure formed by stacking multiple tearable units. Specifically, it can be achieved using a polypropylene film as the substrate. The stacked structure allows for layer-by-layer peeling and replacement, preventing overall failure due to contamination of a single layer. For example, when laying this mat at the entrance of a public place, the surface layer can be directly peeled off after absorbing dust, without the need for complete replacement.

[0031] In another embodiment, the luminous antibacterial adhesive product includes a luminous antibacterial adhesive roller, which includes a plurality of tearable units 1 wound together; in the luminous antibacterial adhesive roller, the adhesive layer 13 is used to contact the object to be cleaned.

[0032] It should be noted that the winding setting refers to multiple tearable units spirally wound around a central axis. Specifically, it can be formed into a continuous roll through a roll pressing process, and the cleaning surface can be automatically replaced using a rotary peeling mechanism.

[0033] The luminous antibacterial adhesive roller is a cylindrical structure formed by winding multiple tearable units 1. Specifically, it can be made using polyethylene film or polypropylene film as the substrate. The winding structure allows for continuous peeling and reduces frequent replacement. During cleaning, the luminous antibacterial adhesive roller winds up multiple tearable units 1, and during rotation, a new layer of adhesive 13 covers the surface.

[0034] In one embodiment, the base film layer 12 is selected from any one of polylactic acid film layer, polybutylene succinate film layer, polyhydroxybutyrate film layer, polyethylene film layer, polypropylene film layer, and OPP film layer.

[0035] In this embodiment, the base film layer 11 is a plastic film that is both elastic and tough, and not easily torn. Exemplarily, it can be any one of a polylactic acid film layer, a polybutylene succinate film layer, a polyhydroxybutyrate film layer, a polyethylene film layer, a polypropylene film layer, or an OPP film layer. Preferably, a plastic film of the same material is used, but different materials can also be used; this is not a limiting factor.

[0036] In one embodiment, the luminescent layer 12 includes a luminescent ink layer. It should be noted that when each peelable unit of the luminescent antibacterial and dust-adhesive product consists of only three layers—a base film layer 11, a luminescent layer 12, and an adhesive layer 13—the luminescent layer 12 can only be a luminescent ink layer and cannot be a luminescent powder layer; otherwise, powder shedding may occur, affecting the user experience.

[0037] In one specific embodiment, the ink used to prepare the luminescent ink layer comprises the following raw materials by weight percentage: 58.4wt%~99wt% UV transparent varnish; 0.2wt%~40wt% luminescent powder; 0.2wt%~0.6wt% antibacterial agent; and 0.4wt%~0.8wt% dispersant.

[0038] It is understandable that luminescent powder is uniformly dispersed in UV transparent varnish to form a luminescent ink layer. When the ambient light level decreases, this material continuously releases visible light through stored light energy. Here, UV transparent varnish refers to a transparent resin matrix with ultraviolet curing properties, specifically achieved using a mixture of acrylate prepolymers and photoinitiators; luminescent powder refers to inorganic or organic materials that store and emit light upon exposure to light, specifically achieved using rare-earth-doped aluminate systems, its function being to continuously release stored light energy in dark environments; and antibacterial agent refers to compounds that inhibit microbial growth, specifically achieved using quaternary ammonium salts or nano-silver.

[0039] In one specific 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% of p-chloro-m-xylenol and 0.2wt%~30wt% of sodium hydroxide.

[0040] 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.

[0041] In one specific embodiment, a method for preparing the above-mentioned luminescent antibacterial dust-adhesive product is further proposed, 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.

[0042] In one embodiment, the thickness of the base film layer is 0.02 mm to 1 mm; and / or, the thickness of the luminescent ink layer is 10 μm to 200 μm; and / or, the thickness of the adhesive layer is 50 μm to 200 μm.

[0043] In a preferred embodiment, the base film layer 11 includes a first base film layer 111 and a second base film layer 112; the tearable unit 1 includes a first base film layer 111, a luminescent layer 12, a second base film layer 112 and an adhesive layer 13 stacked sequentially from top to bottom.

[0044] It should be noted that, in this embodiment, by combining the second base film layer 112 with the adhesive layer 13, it can prevent the adhesive components from penetrating back into the luminescent layer 12, and also allows for layer-by-layer peeling and replacement through the tearable design.

[0045] Through the above technical solution, this application solves the problem that the single-layer base film structure is easily affected by adhesive penetration, thus impacting the 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 12 maintains its luminescent function after multiple peeling operations, thereby continuously improving usability in dim environments.

[0046] In a preferred embodiment, the luminescent layer 12 includes a luminescent powder layer or a luminescent ink layer.

[0047] Specifically, the luminescent antibacterial adhesive product in this embodiment differs from the luminescent antibacterial adhesive product with only one base film layer 11. When the luminescent layer 12 is a luminescent powder layer, the luminescent powder is sandwiched between two base films by rolling, thereby embedding the luminescent powder into the surface of the first base film layer 111 and the second base film layer 112. This avoids the luminescent powder from directly contacting the external environment or adhesive, which could lead to performance degradation. The amount of luminescent powder used is 0.2wt% to 40wt% of the total mass of the film structure. Compared with the technical solution using a luminescent ink layer, this embodiment does not require the preparation of luminescent ink, the production process is simpler, and the production cost is significantly lower.

[0048] In one embodiment, the first base film layer 111 and the second base film layer 112 have the same shape and size.

[0049] It is understandable that during the preparation process, by rolling the first base film layer 111 and the second base film layer 112 and hot-melting their sides, the luminescent powder in the luminescent powder layer is not easily leaked out during use, thereby preventing secondary pollution.

[0050] In one specific embodiment, a method for preparing the above-mentioned luminescent antibacterial dust-adhesive product is further proposed, comprising the following steps: S10. The first base film layer is subjected to constant temperature baking treatment until the first base film layer softens. S20. The softened first base film layer is uniformly coated with phosphorescent powder to form a phosphorescent layer. S21. Lay a second base film layer on the surface of the luminescent layer and roll it; S30. Prepare an adhesive, apply it to the surface of the second 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.

[0051] Among them, constant temperature baking treatment refers to softening the base film layer by controlling the temperature. Specifically, it can be achieved by using a hot air circulating oven at 50℃~80℃ for 5~10 minutes.

[0052] Specifically, after the base film layer 11 is softened by constant temperature baking, its surface forms a slightly molten state. At this time, the phosphorescent powder is evenly embedded into the surface of the base film layer through vibration or electrostatic action. Then, another base film layer 11 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, a tearable unit structure is obtained through curing and cutting.

[0053] The present invention will be further described below through specific embodiments: Example 1 Example 1 is a luminescent antibacterial dust-adhesive floor mat, comprising approximately 30 layers of tearable units 1 stacked together. Each tearable unit 1 includes a base film layer 11, a luminescent layer 12, and an adhesive layer 13 stacked sequentially from top to bottom.

[0054] In Example 1, the base film layer 11 is a PE film with a thickness of 0.02 mm to 1 mm; the luminescent layer 12 is a luminescent ink layer, which includes 70 wt% UV transparent varnish, 25 wt% luminescent powder, 0.3 wt% nano silver, 0.5 wt% dispersant, and the balance being solvent.

[0055] The adhesive corresponding to the adhesive layer 13 in Example 1 includes 99.2 wt% acrylic pressure-sensitive adhesive, 0.4 wt% nano silver and 0.4 wt% acaricide; wherein the acaricide includes 35 wt% p-chloro-m-xylenol, 30 wt% sodium hydroxide and the balance being water.

[0056] The preparation process of the luminescent antibacterial adhesive mat in Example 1 includes the following steps: S10. Perform corona treatment on the base film layer to make its surface tension not less than 50 dyn / cm, and set aside for later use; S20.

S30. Prepare an adhesive and apply it to the surface of the luminescent ink layer in step S20 at a coating speed of 5 m / min. Then, heat-seal and dry it at 80°C to form an adhesive layer. Then, roll it at 50°C with a pressure of 0.5 MPa and then cure it at 25°C for 24 hours to obtain an intermediate. Wrap and cut it to obtain a luminescent antibacterial dust-adhesive mat.

[0060] Example 2 Example 2 is a luminescent antibacterial dust-adhesive mat, which includes approximately 50 layers of tearable units 1 stacked together. Each tearable unit 1 includes a first base film layer 111, a luminescent layer 12, a second base film layer 112, and an adhesive layer 13 stacked from top to bottom.

[0061] In Example 2, the base film layer 11 is a PE film with a thickness of 0.02 mm to 1 mm; the luminescent layer 12 is a luminescent powder layer. The luminescent powder is a lower-cost zinc sulfide-based luminescent powder with a particle size of approximately 200 mesh.

[0062] The adhesive corresponding to the adhesive layer 13 in Example 2 includes 99.2 wt% acrylic pressure-sensitive adhesive, 0.4 wt% nano silver and 0.4 wt% acaricide; wherein the acaricide includes 35 wt% p-chloro-m-xylenol, 30 wt% sodium hydroxide and the balance being solvent.

[0063] The preparation process of the luminescent antibacterial adhesive mat in Example 2 includes the following steps: S10. The first base film layer is baked at a constant temperature of 70°C until it softens. S20. Make the phosphorescent powder uniformly adhered to the surface of the softened first base film layer to form a phosphorescent layer; S21. Lay a second base film layer on the surface of the luminescent layer and roll it on both sides with a pressure of 0.5MPa. S30. Prepare an adhesive and apply it to the surface of the second base film layer after rolling in step S21 at a coating speed of 5 m / min. Then, heat-seal and dry it at 80°C to form an adhesive layer.
