Description

Technical Field

[0001] The utility model belongs to the technical field of sandpaper, and particularly relates to an anti-slip sandpaper. Background Art

[0002] Sandpaper is a paper-like article used for grinding, polishing, and abrasive treatment. One side of it is smooth for holding by hand, while the other side is attached with particles. The side with particles faces the object to be ground, and by rubbing it back and forth against the surface of the object, the surface of the object can be polished and ground.

[0003] A Chinese patent application (or patent) with the publication number CN215283843U discloses a luminous anti-slip sandpaper, which includes a wear-resistant layer. A paper base layer is arranged on the upper end surface of the wear-resistant layer, a fiberglass reinforcement layer is arranged on the upper end surface of the paper base layer, a heat dissipation layer is arranged on the upper end surface of the fiberglass reinforcement layer, a heat insulation layer is arranged on the upper end surface of the heat dissipation layer, a luminous film layer is arranged on the upper end surface of the heat insulation layer, a transparent protective layer is arranged on the upper end surface of the luminous film layer, a particle layer is arranged on the lower end surface of the wear-resistant layer, and a release paper is arranged on the lower end surface of the particle layer. The setting of the fiberglass reinforcement layer can increase the anti-deformation ability of the sandpaper and prevent the sandpaper from being easily deformed and wrinkled during the grinding process; the design of the heat dissipation layer can timely dissipate the heat generated during the grinding process to the surrounding environment and avoid the sandpaper from getting too hot; the design of the luminous film layer can facilitate the taking of the sandpaper in low-light conditions and is convenient to use.

[0004] For the above-mentioned luminous anti-slip sandpaper, a fiberglass reinforcement layer is arranged on the upper end surface of the paper base layer, and a heat dissipation layer is arranged on the upper end surface of the fiberglass reinforcement layer. Among them, the fiberglass reinforcement layer is used to enhance the anti-deformation ability of the anti-slip sandpaper and prevent the sandpaper from being easily deformed and wrinkled during the grinding process. However, the strength of the fiberglass filaments of the fiberglass itself is relatively high. During use, the user needs to hold the paper base layer by hand and then rub the sandpaper on the surface of the object. In this operation, the fiberglass in the fiberglass reinforcement layer will extremely pierce the heat dissipation layer and the paper base layer on both sides of it. After piercing, the fiberglass will cause a certain degree of injury to the user's hand; in addition, a particle layer is arranged on the lower end surface of the wear-resistant layer, a release paper is arranged on the lower end surface of the particle layer, and the particle layer is provided with grit particles and diamond particles. Both types of particles are adhered to the particle layer by an adhesive method. Therefore, when tearing the release paper, the grit particles and diamond particles will also be torn off. For this reason, we provide an anti-slip sandpaper to solve the problems that occur above. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide an anti-slip sandpaper. By using the anti-slip component, the friction between the user's palm and fingers and the base cardboard can be increased during use to achieve an anti-slip effect. By using the heat insulation board and the reinforcing board therein, the overall strength of the sandpaper can be improved. Moreover, the friction particles embedded in the base cardboard will not be affected when disassembling and installing the release cardboard, avoiding the falling of the friction particles, thus solving the problems that occur in the above-mentioned luminous anti-slip sandpaper.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

An installation hole for placing the friction particles is provided at the bottom of the base cardboard. Both the friction particles and the installation hole are in the shape of a frustum of a cone, which ensures that the friction particles inside the base cardboard can be prevented from leaking out from the bottom of the installation hole. At the same time, an adhesive layer is coated on the bottom of the heat insulation board above the friction particles, which can adhere to the top of the friction particles and further improve the non-detachment effect of the friction particles. Finally, the release paper board at the bottom of the base cardboard is adhered to the bottom of the base cardboard by grid-shaped adhesive strips, and the mesh holes are exactly located above the friction particles. Therefore, when tearing and replacing the release paper board, it will not affect the friction particles at the back.
