Description

Technical Field

[0001] This utility model relates to the field of coated paper technology, specifically to a wear-resistant coated paper. Background Technology

[0002] Coated paper is a special type of processed paper made by coating a base paper with one or more layers of a coating material composed of pigments, adhesives, additives, and solvents (usually water) evenly applied. This coating is then dried and calendered. The base paper is typically made from wood pulp or chemimechanical pulp to ensure good strength and surface properties. Pigments in the coating, such as kaolin and calcium carbonate, impart high whiteness and hiding power. Adhesives firmly bond the pigments to the base paper, while additives such as dispersants and lubricants further optimize the coating performance. During production, processes such as blade coating, air knife coating, and roller coating are selected based on product requirements. Precise control of coating thickness and speed ensures a uniform and smooth coating. Coated paper not only possesses excellent optical properties such as high whiteness, high gloss, and good opacity, resulting in vibrant colors and clear contrasts in printed materials, but also exhibits excellent printability due to its smooth surface and uniform ink absorption, enabling clear reproduction of fine images and text. Simultaneously, its physical strength is enhanced, with increased stiffness and tensile strength, meeting various printing and packaging needs.

[0003] Currently, coated paper is often used to process various packaging boxes. During daily use, it will rub against other objects. However, the existing coated paper has poor abrasion resistance and is easily damaged and unusable during friction. Therefore, we propose a wear-resistant coated paper. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant coated paper that improves the wear resistance of the coated paper and effectively prevents it from breaking during friction. This solves the problem that current coated papers are often used to process various packaging boxes, and they will rub against other objects during daily use. However, the existing coated papers have poor wear resistance and are easily damaged and unusable during friction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant coated paper, comprising a coating layer, a first adhesive layer, a second adhesive layer, and a base paper body. The base paper body is fixedly connected to both the upper and lower surfaces of the first adhesive layer. The second adhesive layer is provided on the opposite sides of the two base paper bodies, and the coating layer is provided on the opposite sides of the two second adhesive layers. A plurality of through holes are equidistantly arranged in a rectangular array on the upper surfaces of the two base paper bodies. A protruding post is formed at each through hole position on the upper and lower surfaces of the first adhesive layer, and the protruding post is fixedly connected to the outer surface of the second adhesive layer after passing through the through hole.

[0006] Preferably, both of the opposite sides of the two coating layers are provided with a wear-resistant coating. The wear-resistant coating can improve the wear resistance of the coating layer, effectively prevent the wear of the coating layer, extend the service life of the coating layer, and also protect the base paper.

[0007] Preferably, nylon fibers are provided inside the first adhesive layer, the second adhesive layer, and the protruding post. The nylon fibers increase the strength of the first adhesive layer and the second adhesive layer, and also improve the wear resistance of the second adhesive layer.

[0008] Preferably, the outer surface of the base paper is fixedly connected with sealing strips on all four sides. The sealing strips can prevent the base paper from coming into contact with water, thus effectively protecting the coated paper.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by setting up a base paper body, a first adhesive layer, a second adhesive layer, a through hole, a raised post, and a coating layer, achieves the effect of improving the wear resistance of the coated paper and effectively preventing it from being damaged during friction. The base paper body, the first adhesive layer, the second adhesive layer, and the coating layer constitute the main structure of the coated paper. When the coating layer on the outer surface of the coated paper is worn, the second adhesive layer plays a protective role for the base paper body, effectively preventing the base paper body from being damaged due to wear. Moreover, the sandwich structure formed by the base paper body, the first adhesive layer, and the second adhesive layer effectively improves the strength of the coated paper, making the coated paper less prone to damage when subjected to friction.

[0011] 2. By setting a wear-resistant coating, this utility model can improve the wear resistance of the coating layer, effectively avoid wear of the coating layer, extend the service life of the coating layer, and also protect the base paper.

[0012] 3. By incorporating nylon fibers, this invention effectively increases the strength and bonding strength of the first and second adhesive layers, making it difficult for the two base paper bodies and the base paper body and the coating layer to separate. It also improves the wear resistance of the second adhesive layer. Attached Figure Description

The second adhesive layer 5 is provided on the opposite sides of the two base paper bodies 6, and the coating layer 2 is provided on the opposite sides of the two second adhesive layers 5. A plurality of through holes 9 are equidistantly arranged in a rectangular array on the upper surface of the two base paper bodies 6. A protruding post 8 is formed at each through hole 9 on the upper and lower surfaces of the first adhesive layer 4, and the protruding post 8 is fixedly connected to the outer surface of the second adhesive layer 5 after passing through the through hole 9. An edge sealing strip 1 is fixedly connected to all four sides of the outer surface of the base paper body 6. The edge sealing strip 1 is a waterproof adhesive strip to prevent the base paper body 6 from being damaged by contact with water, thus protecting the base paper body 6.

When the coating layer 2 on the outer surface of the coated paper is worn, the second adhesive layer 5 protects the base paper body 6, effectively preventing the base paper body 6 from being damaged due to wear. Furthermore, the sandwich structure composed of the base paper body 6, the first adhesive layer 4, and the second adhesive layer 5 effectively improves the strength of the coated paper, making it less prone to damage when subjected to friction.
