[0002] Sandpaper is a material used for grinding. It is used to grind the surfaces of metals, wood, etc. to make them smooth and clean. It is usually made by gluing various grinding grains on base paper. The surface of sandpaper has dense particles of different sizes to form different grinding effects. Nowadays, when using sandpaper to grind the surface of an object, you can hold the sandpaper and push it in a reciprocating direction to grind the surface of the object. During grinding, the grinding debris will adhere to the particles of the sandpaper, causing the surface of the sandpaper to slowly flatten, affecting the grinding effect of the sandpaper.

[0021] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0022] A novel composite sandpaper according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.
[0023] Example 1
[0024] For easier understanding, see Figures 1 to 3An embodiment of a new type of composite sandpaper provided by the utility model includes a base layer 1, and grinding collection components are arranged at both ends of the base layer 1; the grinding collection components include a plurality of grinding strips 2, a plurality of through holes 3, a receiving layer 4, and a plurality of support strips 6, the plurality of grinding strips 2 are pasted on one end of the base layer 1, the plurality of through holes 3 are opened at one end of the base layer 1, and the through holes 3 penetrate the base layer 1, and the receiving layer 4 and the plurality of support strips 6 are pasted on one end of the base layer 1.
[0025] It should be noted that, by setting up a grinding collection component, when sandpaper is used to push the surface of an object in a reciprocating direction to grind, the debris generated by grinding can enter the groove between adjacent sanding strips 2 through one side of the arc of the sanding strip 2, and enter the first reinforcement layer 5 and the base layer 1 through the through hole 3 for collection, which can reduce the debris on the surface of the object being grinded, reduce the debris entering between the sandpaper particles, and increase the service life of the sandpaper; the base layer 1 and the receiving layer 4 can be made of kraft paper, and the first reinforcement layer 5 can be made of nylon cloth, and a space for collecting debris is formed between the base layer 1, the receiving layer 4 and the first reinforcement layer 5.
[0026] In some embodiments, Figure 3 As shown, a slot is formed between adjacent grinding strips 2, and a through hole 3 is opened at the slot between adjacent grinding strips 2. One side of the grinding strip 2 is arc-shaped, and the arc-shaped side of the grinding strip 2 corresponds to the edge of one side of the through hole 3.
[0027] It should be noted that when using sandpaper for grinding, the direction of the curved surface on one side of the grinding strip 2 is toward the direction of the sandpaper's retreat, and the sandpaper moves back and forth to grind the surface of the object. When the sandpaper retreats, the curved surface on one side of the grinding strip 2 pushes the debris into the grooves and through holes 3 between adjacent grinding strips 2, and the debris below pushes the debris above into the space between the base layer 1 and the first reinforcement layer 5.
[0028] In some embodiments, Figure 2 As shown, the first reinforcement layer 5 is pasted on one end of the receiving layer 4, and one end of the support bar 6 is pasted on one end of the first reinforcement layer 5. The support bar 6 is located between the base layer 1, the receiving layer 4 and the first reinforcement layer 5. The through hole 3 is connected to the space between the base layer 1 and the first reinforcement layer 5, and a plurality of support bars 6 are arranged obliquely and staggered between the base layer 1 and the first reinforcement layer 5.
[0029] It should be noted that one side of the grinding strip 2 is made of silicon carbide abrasive, and the support strip 6 can be made of silicone strip, which plays a supporting role between the first reinforcement layer 5 and the base layer 1 to prevent the first reinforcement layer 5 and the base layer 1 from being pressed together when pressed, and the support strip 6 is arranged in an inclined and staggered manner to reduce the space occupied and increase the space for collecting debris between the first reinforcement layer 5 and the base layer 1.
[0030] In some embodiments, Figure 1As shown, the second reinforcing layer 7 is adhered to one end of the first reinforcing layer 5 , the adhesive layer 8 is adhered to one end of the second reinforcing layer 7 , and the anti-slip layer 9 is adhered to one end of the adhesive layer 8 .
[0031] It should be noted that graphene paper can be selected for the second reinforcement layer 7. By setting the first reinforcement layer 5 and the second reinforcement layer 7, the nylon cloth and the graphene paper have the characteristics of high strength and high hardness, which can enhance the tear resistance of the sandpaper. The anti-slip layer 9 can be made of anti-slip paper, and a release film is set between the anti-slip layer 9 and the adhesive layer 8, so that the sandpaper can be used by hand, and the anti-slip layer 9 can also be torn off and pasted to other objects through the adhesive layer 8 for use.
[0032] In this embodiment, the adhesive layer 8 may be made of polyurethane adhesive.
[0033] In this example, the grinding strip 2, the base layer 1, the receiving layer 4, the support strip 6, the first reinforcement layer 5, and the second reinforcement layer 7 are bonded to each other from bottom to top with a synthetic resin adhesive.
[0034] Working principle: When using sandpaper for grinding, the curved surface on one side of the grinding strip 2 is directed toward the direction in which the sandpaper retreats, and the sandpaper reciprocates back and forth to grind the surface of the object. When the sandpaper retreats, the curved surface on one side of the grinding strip 2 pushes the debris into the grooves and through holes 3 between adjacent grinding strips 2, and the debris below pushes the debris above into the space between the base layer 1 and the first reinforcement layer 5.
[0035] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
