Description

Technical Field

[0001] This utility model belongs to the field of sanding technology, specifically relating to a fracture-resistant and anti-slip sanding patch. Background Technology

[0002] Skateboarding is an extreme sport, a type of board sport where athletes use their feet to glide across various terrains, surfaces, and facilities, performing complex gliding, jumping, spinning, and flipping maneuvers to music. To increase friction between the skateboard and the shoe sole, a layer of textured material is typically glued to the skateboard surface. However, traditional textured materials rely primarily on a base material layer for toughness and strength, resulting in relatively weak toughness. When the skateboard surface has areas of geometric abrupt changes or significant deformation, over prolonged use, the textured material will develop microcracks due to mechanical wear and fatigue. These microcracks gradually expand under repeated stress, eventually leading to breakage, thus reducing the lifespan of the textured material and limiting its effectiveness.

[0003] A patent with publication number CN207657324U discloses an anti-slip abrasive patch with glitter powder, comprising a multi-layered abrasive patch body. The abrasive patch body has multiple through holes opened by a hollowing process. The abrasive patch body includes, from bottom to top, release paper, adhesive layer, base layer, and surface layer. The release paper is adhered to the lower surface of the adhesive layer, the adhesive layer is adhered to the lower surface of the base layer, and the surface layer is adhered to the upper surface of the base layer. The surface layer is made of anti-slip abrasive particles and glitter powder.

[0004] However, sandpaper is prone to developing longitudinal microcracks under mechanical wear and fatigue during prolonged use. These microcracks gradually expand under repeated stress, eventually leading to fracture. Furthermore, the toughness provided by the sandpaper in the aforementioned solutions largely originates from the substrate, resulting in a relatively weak toughness effect and making the sandpaper susceptible to breakage. This reduces the lifespan of the sandpaper and limits its effectiveness. Summary of the Invention

[0005] To address the problems existing in the background technology, this utility model provides a fracture-resistant and anti-slip sand sticker.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fracture-resistant and anti-slip mat includes a substrate layer, a nylon fiber mesh layer fixedly disposed on the top of the substrate layer, and an aluminum alloy layer fixedly disposed on the top of the nylon fiber mesh layer. An anti-slip layer is bonded to the top of the aluminum alloy layer by a first adhesive layer, and release paper is bonded to the bottom of the substrate layer by a second adhesive layer. Several aluminum alloy posts are fixedly disposed at the bottom of the aluminum alloy layer. The nylon fiber mesh layer is arranged in a grid pattern, and the posts correspond to the mesh openings of the nylon fiber mesh layer. Each post is inserted into the corresponding mesh opening of the nylon fiber mesh layer.

[0008] Furthermore, the anti-slip layer, the first adhesive layer, the aluminum alloy layer, the nylon fiber mesh layer, the substrate layer, the second adhesive layer, and the release paper are arranged sequentially from top to bottom; each of the anti-slip layer, the first adhesive layer, the aluminum alloy layer, the substrate layer, the second adhesive layer, and the release paper has several through holes; the several through holes on the anti-slip layer, the first adhesive layer, the aluminum alloy layer, the substrate layer, the second adhesive layer, and the release paper are connected one-to-one and form multiple sets of channels, which are symmetrically distributed on both sides of the sandpaper.

[0009] Furthermore, the anti-slip layer is provided with abrasive particles, which are made of corundum.

[0010] Furthermore, the substrate layer is made of waterproof PVC material, and the first adhesive layer and the second adhesive layer can be made of tape or glue.

[0011] This application has the following beneficial effects:

[0012] By incorporating an aluminum alloy layer and a nylon fiber mesh layer, and leveraging the high toughness of both, the toughness of the sandpaper in this design is diversified, significantly improving its overall toughness and ensuring its service life. Simultaneously, several aluminum alloy posts are placed at the bottom of the aluminum alloy layer and inserted into the mesh of the nylon fiber mesh layer. This not only significantly improves the bonding strength between the aluminum alloy and nylon fiber mesh layers but also enhances their interlocking performance, further improving the sandpaper's toughness and resulting in better overall practical performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: a fracture-resistant and anti-slip sand patch, including a substrate layer 4, a nylon fiber mesh layer 3 fixedly disposed on the top of the substrate layer 4, and an aluminum alloy layer 2 fixedly disposed on the top of the nylon fiber mesh layer 3. Both the nylon fiber mesh layer 3 and the aluminum alloy layer 2 have good toughness, which can improve the strength and toughness of the sand patch.

[0021] The top of the aluminum alloy layer 2 is bonded with an anti-slip layer 1 by a first adhesive layer 5, and the bottom of the substrate layer 4 is bonded with release paper 6 by a second adhesive layer 9.

[0022] The anti-slip layer 1, the first adhesive layer 5, the aluminum alloy layer 2, the nylon fiber mesh layer 3, the substrate layer 4, the second adhesive layer 9, and the release paper 6 are arranged sequentially from top to bottom. Several through holes 7 are opened on the anti-slip layer 1, the first adhesive layer 5, the aluminum alloy layer 2, the substrate layer 4, the second adhesive layer 9, and the release paper 6. The through holes 7 on the anti-slip layer 1, the first adhesive layer 5, the aluminum alloy layer 2, the substrate layer 4, the second adhesive layer 9, and the release paper 6 are connected one-to-one and form multiple sets of channels. The multiple sets of channels are symmetrically distributed on both sides of the sandpaper.

[0023] When applying the anti-slip abrasive to the skateboard surface, the abrasive is relatively large and easily forms air bubbles between the second adhesive layer 9 and the skateboard surface. These air bubbles prevent the abrasive from adhering completely to the skateboard surface. The channels formed by the through-holes 7 increase the space between the second adhesive layer 9 and the skateboard surface, allowing for better contact with the outside environment and preventing air bubbles from forming during the application process. Furthermore, distributing the channels evenly on both sides of the abrasive allows the operator to squeeze out air from the center outwards, facilitating air expulsion and resulting in a smoother abrasive surface after air removal.

[0024] The anti-slip layer 1 has abrasive particles, which can be made of corundum. When the sole of the shoe steps on the corundum surface, it can create a good friction effect. The base layer 4 is made of waterproof PVC material, and the first adhesive layer 5 and the second adhesive layer 9 can be made of tape or glue.

[0025] In addition, several aluminum alloy posts 8 are fixedly installed at the bottom of the aluminum alloy layer 2. The posts 8 are evenly distributed at the bottom of the aluminum alloy layer 2, and the bottom of the posts 8 is smoothly curved. The nylon fiber mesh layer 3 is arranged in a grid pattern, and the posts 8 correspond to the mesh openings of the nylon fiber mesh layer 3. Inserting several posts 8 into the mesh openings of the nylon fiber mesh layer 3 can not only significantly improve the bonding strength between the aluminum alloy layer 2 and the nylon fiber mesh layer 3, but also enhance the interlocking performance and the degree of bonding between the two, further improving the toughness of the sandpaper, ensuring the service life of the sandpaper, and resulting in better overall practical effect.

[0026] Working principle: When using, peel off the release paper 6 at the bottom of the second adhesive layer 9 and attach the bottom of the second adhesive layer 9 to the skateboard surface. The diamond abrasive on the anti-slip layer 1 can ensure the friction effect brought by the abrasive.

[0027] The strength and toughness of the sandpaper can be improved by using the nylon fiber mesh layer 3 and the aluminum alloy layer 2. Furthermore, inserting several posts 8 into the mesh of the nylon fiber mesh layer 3 can not only significantly improve the bonding strength between the aluminum alloy layer 2 and the nylon fiber mesh layer 3, but also enhance the interlocking performance and the degree of bonding between the two, further improving the toughness of the sandpaper and ensuring its service life.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
