Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper, in particular to moisture-proof and mildew-proof corrugated paper and a production process. Background Art

[0002] Corrugated paper, thanks to its superior mechanical properties and processing capabilities, has gradually replaced traditional wood panels as the primary material for transport packaging. In addition to effectively protecting objects, corrugated paper can also be printed with patterns and text, playing a significant role in beautification and promotion. However, existing corrugated paper has a relatively simple structure, typically consisting of a wavy core layer and a surface layer. This makes wrapped objects susceptible to moisture and bacterial erosion, leading to dampness and mold. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a moisture-proof and mildew-proof corrugated paper and a production process, which can prevent objects wrapped by the corrugated paper from being easily corroded by water vapor and bacteria.

[0004] The present invention adopts the following technical solutions.

[0005] A moisture-proof and mildew-proof corrugated paper comprises base paper, wherein the top and bottom sides of the base paper are respectively provided with wavy interlayer paper, and the side of the interlayer paper facing away from the base paper is provided with surface paper, and a receiving cavity is formed between the trough of the interlayer paper close to the base paper and the surface paper, and the receiving cavity is evenly distributed with a plurality of sealing members along its length, and the plurality of sealing members divide the receiving cavity into a plurality of receiving chambers, and the receiving chambers are filled with desiccant particles and mildew-proof agent particles, and the surface paper is penetrated by a plurality of air holes connected to the receiving chambers.

[0006] Furthermore, the wave direction of the top interlayer paper is perpendicular to the wave direction of the bottom interlayer paper.

[0007] A production process for moisture-proof and mildew-proof corrugated paper, the process comprising the following steps:

[0008] S1. Preheating the interlayer paper by using a heating roller, and pressing the preheated interlayer paper into a corrugated shape by using a corrugating machine;

[0009] S2. Using a multi-point glue applicator, apply multiple lines of glue paste evenly distributed on the top side of the interlayer paper obtained in step S1 and extending along the direction of the wave.

[0010] S3, using a spatula to horizontally draw the glue line obtained in step S2 along the direction of the wave, and smear the portion of the glue line on the crest into the trough to achieve leveling of the glue line;

[0011] S4. Using a hot air blower to heat the glue line that has been flattened in step S3, hardening the portion of the glue line located in the trough into a blocking piece. The blocking pieces divide the trough into a plurality of receiving chambers.

[0012] S5. Mixing the desiccant particles and the mildew-proofing agent particles in proportion and spreading them on the top side of the interlayer paper treated in step S4, and vibrating the interlayer paper with a vibrator to evenly distribute the desiccant particles and mildew-proofing agent particles to each receiving chamber;

[0013] S6. Preheating the surface paper using a heating roller and applying glue on the top side of the surface paper using a roller glue applicator;

[0014] S7, using a scraper to scratch the top side of the surface paper treated in step S6 to control the thickness of the glue;

[0015] S8. Turn the top paper treated in step S7 over so that the glued side of the top paper faces downward, and use a bonding machine to bond the bottom side of the top paper to the top side of the interlayer paper treated in step S5. Then, allow the paper to cool to harden the glue between the top paper and the interlayer paper.

[0016] S9, using a needle loom to create a plurality of ventilation holes on the surface paper treated in step S8;

[0017] S10, preheating the base paper using a heating roller, and applying glue on the top and bottom of the base paper using a roller glue applicator;

[0018] S11, using a scraper to scratch the top and bottom sides of the base paper treated in step S10 to control the thickness of the glue;

[0019] S12. Using a bonding machine, bond the interlayer paper treated in step S9 to the top and bottom sides of the base paper treated in step S11, respectively. The interlayer paper is bonded to the base paper on the side facing away from the surface paper, and the wave direction of the top interlayer paper is perpendicular to the wave direction of the bottom interlayer paper. The paper is then allowed to cool to harden the glue between the base paper and the interlayer paper.

[0020] Furthermore, in step S1, the wave height of the interlayer paper is 5 mm to 10 mm.

[0021] Furthermore, in step S2, the width of the glue line is 3 mm to 5 mm, and the thickness is half of the wave height of the interlayer paper.

[0022] Furthermore, the radius of the desiccant particles and the mildewcide particles in step S5 is 2 mm to 3 mm.

[0025] The beneficial effects of the present invention are:

[0026] The corrugated paper of the present invention is provided with desiccant particles and mildewcide particles. During use, the desiccant particles absorb moisture from the air, while the mildewcide particles slowly release a sterilizing gas, making objects wrapped in the corrugated paper of the present invention less susceptible to moisture and bacterial corrosion. Furthermore, the desiccant and mildewcide particles are stored in multiple storage chambers. If one chamber is damaged, the particles in other intact chambers will not leak, thus enhancing the usability.

[0027] In addition, the production process of the present invention is also relatively reasonable and simple. BRIEF DESCRIPTION OF THE DRAWINGS
