Description

Technical Field

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

[0002] Laminated paper is a type of paper product with special functions. It uses base paper as a substrate and coats its surface with a uniform layer of plastic film, typically thermoplastic such as polyethylene (PE). This coating not only gives the paper excellent waterproof and moisture-proof properties, preventing the intrusion of external moisture and protecting the packaged goods from moisture and deterioration, but also possesses excellent oil-resistant properties, effectively preventing grease penetration. It is ideal for packaging oily foods. Furthermore, laminated paper has a certain strength and toughness, is not easily torn, and has a smooth, flat surface with good printability, allowing for exquisite pattern printing and text labeling, enhancing the aesthetics and appeal of the packaging. In addition, depending on different application requirements, laminated paper can undergo special treatments, such as adding a heat insulation layer to reduce heat transfer, or being made into release paper for the production of tapes, labels, and other products, facilitating product peeling and use. Laminated paper is widely used in food, pharmaceuticals, electronics, construction, and many other fields, and is an indispensable material in the modern packaging industry.

[0003] Currently, when coated paper is used, the coating layer on its surface is easily damaged when it is scratched by external force, and may even cause the coating layer to separate from the base paper layer. To address this, we propose a highly scratch-resistant coated paper. Utility Model Content

[0004] The purpose of this invention is to provide a highly scratch-resistant coated paper, which enhances the bonding strength between the coated layer and the base paper layer, improves the scratch resistance of the coated layer surface, and effectively prevents the coated layer from being damaged by external scratches and from separating from the base paper layer. This solves the problem that the coated layer of current coated paper is prone to surface damage when subjected to external scratches, and may even lead to separation between the coated layer and the base paper layer.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high scratch-resistant coated paper, comprising a base paper body and a coating layer, wherein the base paper body is provided with a coating layer on its upper surface, and the coating layer is provided with a smooth and wear-resistant coating on its upper surface, wherein a plurality of bonding grooves are uniformly provided on the upper surface of the base paper body, and a raised point is formed at each bonding groove position on the lower surface of the coating layer, and the raised point is located inside the bonding groove.

[0006] Preferably, the coating layer contains polyamide fibers. Polyamide fibers have high strength and good toughness. Adding them to the coating layer can significantly improve the tensile strength, tear resistance and puncture resistance of the coating layer. At the same time, polyamide fibers have good wear resistance, which can make the coating layer more wear-resistant and extend the service life of the coating layer.

[0007] Preferably, the upper surface of the coating layer is provided with a film, which covers the coating layer and effectively prevents dust and impurities from adhering to the surface of the coating layer during the transportation of the coating paper. At the same time, it also protects the coating layer and prevents it from being scratched. The film can be removed before the coating paper is used.

[0008] Preferably, the lower surface of the base paper body is provided with a heat insulation layer. The heat insulation layer mainly serves to prevent heat transfer. It can effectively reduce the transfer of external heat to the packaged items, preventing the items from deteriorating, deforming or being damaged due to heat.

[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 bonding groove, a coating layer, a smooth and wear-resistant coating, and raised points, achieves the effect of enhancing the bonding strength between the coating layer and the base paper layer, improving the scratch resistance of the coating layer surface, effectively preventing the coating layer on the surface of the coated paper from being damaged by external scratches and the phenomenon of separation between the coating layer and the base paper layer. The smooth and wear-resistant coating can improve the smoothness of the coating layer surface, so that the coefficient of friction of the coating layer is reduced when scratching occurs, reducing the friction force during scratching, and improving the wear resistance of the coating layer, effectively preventing the coating layer from being damaged by scratches. At the same time, the raised points on the coating layer are inserted into the bonding groove, which improves the bonding strength between the coating layer and the base paper body, making it less likely for the coating layer to separate from the base paper body when scratching occurs.

[0011] 2. By incorporating polyamide fibers, this invention achieves the effect of further improving the strength and wear resistance of the coating layer. Polyamide fibers have high strength and good toughness. When added to the coating layer, they can significantly improve the tensile strength, tear resistance, and puncture resistance of the coating layer. At the same time, the good wear resistance of polyamide fibers can make the coating layer more wear-resistant and extend its service life.

[0012] 3. By setting a film, this utility model covers the coated layer, effectively preventing dust and impurities from adhering to the surface of the coated layer during the transportation of the coated paper. It also protects the coated layer from scratches. The film can be removed before the coated paper is used. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-4 As shown, the present invention proposes a high scratch-resistant coated paper, comprising a base paper body 1 and a coating layer 3. The upper surface of the base paper body 1 is provided with the coating layer 3, and the upper surface of the coating layer 3 is provided with a smooth and wear-resistant coating 4, which is a nano-composite coating. The upper surface of the base paper body 1 is uniformly provided with a plurality of bonding grooves 6, and the lower surface of the coating layer 3 forms a raised point 7 at the position of each bonding groove 6, and the raised point 7 is located inside the bonding groove 6. When the coating layer 3 is applied to the base paper body 1 through the coating process, the raised point 7 is simultaneously formed inside the bonding groove 6.

[0021] In this embodiment, the smooth and wear-resistant coating 4 can improve the smoothness of the surface of the coating layer 3, thereby reducing the coefficient of friction when the coating layer 3 is scratched, reducing the friction force during scratching, and improving the wear resistance of the coating layer 3. This effectively prevents the coating layer 3 from being damaged due to scratching. At the same time, the protruding points 7 on the coating layer 3 are inserted into the bonding groove 6, which improves the bonding strength between the coating layer 3 and the base paper body 1, making it less likely for the coating layer 3 to separate from the base paper body 1 when scratching occurs, thereby improving the scratch resistance of the coated paper.

Compared with Embodiment 1, this embodiment further includes a polyamide fiber 8 disposed inside the coated layer 3, a film 5 disposed on the upper surface of the coated layer 3, and a smooth and wear-resistant coating 4 located between the film 5 and the coated layer 3. The film 5 covers the coated layer 3, effectively preventing dust and impurities from adhering to the surface of the coated layer 3 during the transportation of the coated paper, and also protecting the coated layer 3 from scratches. Before using the coated paper, the film 5 can be removed. A heat insulation layer 2 is disposed on the lower surface of the original paper body 1. The heat insulation layer 2 mainly serves to prevent heat transfer. It can effectively reduce the transfer of external heat to the packaged items, preventing the items from deteriorating, deforming or being damaged due to heat.

[0024] In this embodiment, polyamide fiber 8 has high strength and good toughness. When added to the coating layer 3, it can significantly improve the tensile strength, tear resistance and puncture resistance of the coating layer 3. At the same time, polyamide fiber 8 has good wear resistance, which can make the coating layer 3 more wear-resistant and extend the service life of the coating layer 3.
