Description

Technical Field

[0001] The utility model relates to the field of antibacterial and mildew-proof corrugated paper, in particular to antibacterial and mildew-proof corrugated paper and a production device thereof. Background Art

[0002] According to the requirements of the new version of the plastic ban, the selection of express packaging materials is increasingly inclined to the principle of sustainability. In addition to requiring packaging materials to be green and degradable, they are also required to be quickly recycled and reused. Therefore, paper packaging materials have become the focus of attention in the papermaking industry, especially industrial packaging paper. Paper packaging materials are widely used in the transportation and packaging of various industries such as food, home appliances, textiles, food industry, and daily chemicals. However, during the production and processing process, some microorganisms such as bacteria and mold usually invade, causing the packaging paper to be contaminated, and then contaminating its contents. In addition, since paper packaging materials are mainly made of plant fibers after pulping, cellulose has adsorption capacity and can absorb moisture in the air and on the contact surface. Especially in coastal provinces with high temperature and humidity, packaging paper is prone to moisture resurgence, bacterial growth, and mold, which reduces the performance of the packaging paper, reduces quality, and increases transportation costs. For example, corrugated boxes, as a lightweight, environmentally friendly, low-cost, and high-strength packaging material, are constantly expanding in scope of application. However, the surface of the carton is easy to absorb water, and its various properties are greatly reduced after being damp. In addition, the surface of processed cartons is usually coated with paint, ink, color, etc., which makes the cartons and contents susceptible to problems such as mold and mildew. Therefore, it is very necessary to give the packaging base paper "antibacterial and mildew-proof" function. At present, most packaging papers do not have antibacterial properties, so the research and development of corrugated paper with antibacterial and mildew-proof technology is of great research significance.

[0003] At present, the processing methods of antibacterial and mildew-proof packaging paper mainly include the following: (1) Coating processing method: Usually, the antibacterial agent and other materials are first prepared into a mixed liquid, and then the mixed liquid containing the antibacterial agent is coated on the surface of the paper by a surface coating method, and the antibacterial paper is obtained after drying. For example, Nisin and chitosan are used as antibacterial agents, and vinyl acetate-ethylene copolymer is used as an adhesive medium to prepare antibacterial paper by coating. This antibacterial paper significantly inhibits the activity of Listeria and Escherichia coli, and can improve the microbial stability of milk and orange juice stored at 10°C. The coating method has the advantages of simple operation, low production cost, good uniformity, easy control of dosage, and suitability for industrial production. (2) Spraying / immersion method: Antibacterial paper is prepared by spraying, sprinkling or immersion. Although this method can make the retention rate of the antibacterial agent higher, spraying and immersion can easily lead to uneven moisture distribution of the paper, which in turn affects the mechanical strength of the paper, and problems such as paper breakage may occur during the production process. (3) Wet-end addition method: Antimicrobial agents are added to the pulp before papermaking, and then antimicrobial paper is prepared. For example, natural antimicrobial agents such as chitin and its derivatives are used to obtain antimicrobial fibers through spinning, which are mixed with pulp for modification to prepare antimicrobial paper. The wet-end addition method is suitable for industrial production and basically does not require the addition of additional process links and equipment. However, this method is prone to waste of antimicrobial agents. It is necessary to consider the recycling and reuse of antimicrobial agents that are not attached to the paper, and to prevent the reaction or interference between the antimicrobial agent and the pulp and other additives. (4) Fiber modification method: The cellulose structure is mainly modified by chemical modification, physical modification or biological modification, so that the fiber itself has antibacterial function and antimicrobial paper is prepared. For example, the antimicrobial agent Mg(OH)2 nanoparticles are directly added to wood pulp. The prepared paper can effectively inhibit Escherichia coli, and the antibacterial rate increases with the increase of the amount of nanoparticles added. The fiber modification method is relatively complicated and requires the search for natural antimicrobial agents that are non-toxic and easy to extract from fibers. (5) Corrugated paper structure design: mainly through some structural designs, the air permeability, waterproofness, strength and other properties of corrugated paper packaging materials are improved, and at the same time combined with the use of antibacterial and mildew-proof agents, the antibacterial and mildew-proof effects are finally achieved.

[0004] At present, the research on antibacterial and mildew-proof technology for corrugated paper is only in the preliminary stage, and there are few commercial products. The road to developing safe, green and efficient antibacterial and mildew-proof corrugated paper is long and arduous. The main problems are as follows:

[0005] 1. Additional manufacturing equipment and corresponding processes are required. For example, the coating process and spray / immersion process require additional coating and spray equipment.

[0006] Second, the amount of antibacterial and antifungal agents required in the above technology is large and the cost is high;

[0007] Third, the coating process and the spraying / immersion process have problems such as the corrugated paper losing its strength structure due to moisture because a relatively large amount of liquid is required to contact the surface of the paper material.

[0008] The wet-end addition method and the fiber modification method have problems such as damaging the pulp properties and wasting the antibacterial and mildew-proof agent being encapsulated inside the paper product. Utility Model Content

[0040] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0041] Please refer to Figure 1 to Figure 2The utility model provides an antibacterial and mildew-proof corrugated paper, comprising a corrugated paper body and an antibacterial and mildew-proof agent arranged on the surface of the corrugated paper body.

[0042] Wherein, the antibacterial and mildew-proof agent is evenly distributed on the surface of the corrugated paper body in the form of dots;

[0043] When in use, the placement of the antibacterial and mildew-proof agent makes the corrugated paper body have antibacterial and mildew-proof functions, greatly improving its service life. The uniformly dotted antibacterial and mildew-proof agent can prevent a large amount of liquid from contacting the surface of the paper material, causing the corrugated paper to lose its strength structure due to moisture, while reducing the time and cost of drying. The principle of this application is that the antibacterial and mildew-proof agent has a certain inhibition zone. For example, if an area with a diameter of 2mm is printed with the antibacterial and mildew-proof agent at a certain point, then there will be an inhibition zone of 5 to 10mm around this point, that is, an area with antibacterial and mildew-proof effects. Therefore, the entire area is not fully coated, but selectively dotted in some areas.

[0044] A production device for antibacterial and mildew-proof corrugated paper, comprising an industrial corrugated paper printer, an ink cartridge and a drying mechanism;

[0045] The ink cartridge is installed in the industrial corrugated paper printer, and the ink cartridge contains an antibacterial and anti-mildew agent;

[0046] The drying mechanism is installed at the discharge port of the industrial corrugated paper printer.

[0047] Wherein, the industrial corrugated paper printer adopts a dot matrix printing pattern to print the antibacterial and mildew-proof agent in the ink cartridge on the surface of the corrugated paper body;

[0048] The antibacterial and antifungal agent is a highly dispersed composite nano antibacterial and antifungal agent ink;

[0049] The printing mode adopted in this application is a special dot matrix printing, not the traditional printing that fills the entire page. The advantages of this method are:

[0050] 1. Save the use of antibacterial and antifungal agents;

[0051] 2. Using less ink can prevent a large amount of liquid from coming into contact with the surface of the paper material, causing the corrugated paper to lose its strength structure due to moisture;

[0052] 3. Using less ink can reduce drying time and cost.

[0053] In this embodiment, the drying mechanism 3 includes a conveyor belt 31, a drying component 32 and a rolling and dust removal component 33. The movement starting end of the conveyor belt 31 is connected to the discharge end of the industrial corrugated paper printer, and the drying component 32 and the rolling and dust removal component 33 are sequentially installed on the conveyor belt 31;

[0054] Wherein, the drying component 32 adopts an infrared drying machine.

[0055] The rolling dust removal assembly 33 includes a support frame 333, a rolling roller 331 and a negative pressure dust removal nozzle 332;

[0056] The cross section of the support frame 333 is a convex structure;

[0057] The flattening rollers 331 are provided in two groups and are rotatably mounted in the support frame 333 , and the gap between the flattening rollers 331 and the conveyor belt 31 is the flattening gap;

[0058] The negative pressure dust removal nozzle 332 is disposed between the two groups of flattening rollers 331 .

[0059] In this embodiment, after the corrugated paper body is printed by the industrial corrugated paper printer, the antibacterial and mildew-proof agent is arranged on the surface of the corrugated paper body. After the corrugated paper body is transported by the conveyor belt 31, it moves to the drying component 32, and is dried by the drying component 32. The dried corrugated paper body enters the support frame 333, and after being rolled by the flattening roller 331, the flatness of the corrugated paper body can be improved. In the flattening process, the negative pressure dust removal nozzle 332 sucks out dust or impurities that may exist on the surface of the corrugated paper body.

[0060] The working principle of the utility model is as follows:

[0061] The layout of the antibacterial and mildew-proof agent makes the corrugated paper body have antibacterial and mildew-proof functions, greatly improving its service life. The uniformly dotted antibacterial and mildew-proof agent can prevent a large amount of liquid from contacting the surface of the paper material, causing the corrugated paper to lose its strength structure due to moisture, while reducing the time and cost of drying. The principle of this application is that the antibacterial and mildew-proof agent has a certain inhibition zone. For example, if an area with a diameter of 2mm is printed on a certain point, then there will be an inhibition zone of 5 to 10mm around this point, that is, an area with antibacterial and mildew-proof effects. Therefore, the entire area is not fully coated, but selectively printed in some areas.
