[0018] The present application will be further described in detail below with reference to the accompanying drawings.
[0019] Please see Figure 1 and Figure 2 This application discloses an anti-mildew and antibacterial corrugated cardboard box, comprising a corrugated cardboard 1, which includes at least one corrugated board layer 11, which includes corrugated core paper 111 and inner paper 112 bonded together, and an outermost corrugated core paper 111 bonded with a face paper 12. The key feature is that a layer of desiccant particles 2 is laid on the corrugated core paper 111, and a liquid antibacterial agent 3 is sprayed on one side of the desiccant particle layer 2. The desiccant particles 2 are silica gel desiccants, and the antibacterial agent 3 is a curable quaternary ammonium salt.
[0020] Specifically, a corrugated cardboard box is a box body made by cutting and folding corrugated cardboard 1, with desiccant granules 2 placed in the middle of the corrugated cardboard 1, and a liquid antibacterial agent 3 sprayed on the desiccant granule 2 layer.
[0021] In this way, by setting up a layer of desiccant particles 2 and antibacterial agent 3, a dry environment is formed by the desiccant particles 2, and bacterial growth is inhibited by the antibacterial agent 3, reducing the possibility of mold. At the same time, the desiccant particles 2 achieve the drying effect by adsorbing moisture. The liquid antibacterial agent 3 is atomized and sprayed onto the layer of desiccant particles 2. Through the adsorption of the desiccant particles 2, some of the antibacterial agent 3 is adsorbed, achieving a longer-lasting antibacterial effect.
[0022] Depending on the specific application environment, silica gel desiccant works by removing water molecules from damp substances through adsorption. Its porous structure provides a large surface area, allowing for better dehumidification while also maximizing the retention of the liquid antibacterial agent 3, thus extending its antibacterial effect. Furthermore, macroporous silica gel often serves as a catalyst carrier in reactions, making it more suitable for the release of antibacterial agent 3, resulting in a superior antibacterial effect.
[0023] Corrugated cardboard boxes are typically products used multiple times or stored for extended periods. Curable quaternary ammonium salts offer a longer-lasting antibacterial effect compared to other antibacterial materials. Furthermore, curable quaternary ammonium salts are colorless, odorless, and have stable performance. Since corrugated cardboard requires exposure to high temperatures during manufacturing, curable quaternary ammonium salts exhibit excellent light and heat resistance, making them more adaptable to various usage environments.
[0024] In some feasible methods, the desiccant particles 2 (silica gel) are macroporous silica gel. Macroporous silica gel is often used as a catalyst carrier in reactions, and it is also more suitable for the release of antibacterial agent 3, thus giving it a better antibacterial effect.
[0025] Furthermore, the desiccant particles 2 are embedded into the corrugated core paper 111 layers by high-pressure injection.
[0026] It should be understood that the desiccant particles 2, as silica gel desiccant, mainly achieve the drying effect through surface adsorption. The desiccant particles 2 are fixed by embedding them into the corrugated core paper 111 layers through high-pressure spraying, which reduces the impact of adhesive adhering to the desiccant particles 2 on their performance when using bonding methods.
[0027] Furthermore, antibacterial agent 3 is sprayed on both sides of the face paper 12 and the inner paper 112.
[0028] It should be understood that by spraying antibacterial agent 3 on both sides of the face paper 12 and the inner paper 112, the curable quaternary ammonium salt also forms an antibacterial film layer on the surface of the face paper 12 and the inner paper 112, reducing the possibility of mold growth.
[0029] As a specific embodiment of the anti-mildew and antibacterial corrugated cardboard box provided in the application, the face paper 12 and the inner paper 112 are provided with a number of breathable micropores.
[0030] It should be understood that one of the causes of mold growth is a humid environment. By setting up a breathable microporous structure, the ventilation of the corrugated cardboard 1 is increased, while the moisture retention of the face paper 12 is reduced, allowing more moisture to enter the corrugated core paper 111 layer, which is then absorbed by the desiccant particles 2, reducing the moisture content of the corrugated cardboard 1 and thus inhibiting mold growth.
[0031] This application also discloses a method for producing the above-mentioned anti-mildew and antibacterial corrugated cardboard box, including: a. Place the paperboard roll on the paperboard holder and place the free end of the paperboard in the working position; b. The paperboard base paper enters the preheating equipment for preheating; c. The 111-layer corrugated core paper and the 112-layer liner paper enter the single-facer, and the 12-layer face paper enters the double-facer. d. The corrugated core paper 111 layers are laid with desiccant granules 2 layers by the desiccant granule 2 laying equipment; e. The 111-layer corrugated core paper, 112-layer inner paper, and 12-layer face paper are sprayed with antibacterial agent 3 using an antibacterial agent 3 spraying equipment; f. The 111-layer corrugated core paper is pressed into 111 layers of corrugated core paper by a single-facer corrugated roll; g. The 111th layer of corrugated core paper and the 112th layer of inner paper are glued together by a single-facer. h. The 111th layer of corrugated core paper and the 112th layer of liner paper enter the double-facer and are glued together with the 12th layer of face paper to form corrugated cardboard 1. i. Corrugated cardboard 1 is cut to the appropriate size using a cutting machine; j. Corrugated cardboard 1 enters the printing and slotting equipment for printing, slotting, corner cutting, creasing and edge trimming; k. Use a nailing device to nail the corrugated cardboard board 1 end to end.
[0032] Depending on the specific application scenario, the 111-layer corrugated core paper is pressed into shape by the corrugated rollers of a single-facer. The desiccant granule layer 2 is placed before the 111-layer corrugated core paper is formed. After the desiccant granule 2 is laid, the pressing by the corrugated rollers facilitates the embedding of the desiccant granule 2. At the same time, the 111-layer corrugated core paper is in a flat state, which makes it easier to lay the desiccant granule layer 2 evenly compared to the wavy shape after pressing.
[0033] Furthermore, in step e, the corrugated core paper 111 layers, the inner paper 112 layers, and the outer paper 12 layers are all sprayed with antibacterial agent 3 on both sides.
[0034] To facilitate understanding of the production method in this embodiment, this embodiment also discloses an apparatus for producing mildew-proof and antibacterial corrugated boxes. Please refer to [link to relevant documentation]. Figure 3 It includes a first paper roll 411 and a second paper roll 412. Multiple spray guns 42 are arranged in an array between the first paper roll 411 and the second paper roll 412. The spray guns 42 are connected to an air pump 43. A feeding section 44 is connected to the upper side of the spray guns 42. Desiccant particles 2 are disposed in the feeding section 44.
[0035] Depending on the specific usage environment, the desiccant particles 2 in the feeding section 44 are sprayed onto the base paper of the corrugated core paper 111 layer at a certain air pressure through the spray gun 42, so that the desiccant particles 2 are embedded in the base paper.
[0036] Furthermore, the plane containing the axes of the first paper roll 411 and the second paper roll 412 is perpendicular to the horizontal plane.
[0037] Depending on the specific usage environment, by setting the base paper to run vertically and horizontally, when some desiccant particles 2 are not embedded, they will automatically fall off, reducing resource waste.
[0038] A method for producing anti-mildew and antibacterial corrugated boxes involves setting a linerboard 45 with a rough surface on one side of the original cardboard, allowing some desiccant particles 2 to penetrate the original paper.
[0039] In some feasible embodiments, the first paper roll 411 and the second paper roll 412 are motor-driven circular rolls. The paper passes through the first paper roll 411 and the second paper roll 412 before entering the single-facer. A spray gun 42 is provided between the first paper roll 411 and the second paper roll 412, with the nozzle of the spray gun 42 facing the paper between the first paper roll 411 and the second paper roll 412. The end of the spray gun 42 is connected to an air pump 43. The feeding section 44 is a cylindrical shape with a conical bottom and is located on the side of the spray gun 42. The desiccant particles 2 in the feeding section 44 fall into the spray gun. Inside 42, air pressure is provided by air pump 43 to spray out the desiccant particles 2, which are embedded in the original paperboard. A liner 45 is also provided. The liner 45 is located on the side of the original paperboard away from the spray gun 42 and is attached to the original paperboard so that the desiccant particles 2 sprayed by the spray gun 42 will not fall through the original paper. At the same time, the side of the liner 45 that is attached to the original paperboard is rough, so that some desiccant particles 2 can penetrate the original paper on one side. The size of the pits and depressions on the rough surface should not be greater than the average particle size of the desiccant particles 2, and the depth should not exceed half the average particle size of the desiccant particles 2, so that the desiccant particles 2 are stuck in the original paper after penetrating it but do not fall off.
[0040] In some feasible methods, an antibacterial agent spraying device 5 is provided below the spray gun 42, which sprays the antibacterial agent 3 into the corrugated core paper 111 base paper embedded with desiccant particles 2 by a high-pressure pump.
[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
