[0002] Sponge sand is often used to grind the surfaces of metals, woods, etc. to make them smooth and shiny. The existing sponge sand blocks are formed by implanting a grinding sand layer on the sponge. The water absorption of sponge sand mainly comes from the porous structure of the sponge, and it is relatively easy for liquid to enter and exit the sponge. Therefore, there is a problem that the water locking property of sponge sand is not good, that is, after the polishing liquid enters the sponge sand, it will also flow out quickly, resulting in low utilization rate of the polishing liquid.

[0031] Sponge sand, please refer to Figures 1-3 As shown, it includes: a base material layer 100, a metal mesh layer 200, and an abrasive layer 300.

[0032] The metal mesh layer 200 covers at least the upper surface and the lower surface of the base material layer 100, and the abrasive layer 300 covers the metal mesh layer 200 and corresponds to the upper surface and the lower surface of the base material layer 100.

[0033] In this embodiment, the shape of the base material layer 100 is designed as a three-dimensional rectangle.

[0034] A water-locking cloth 110 is provided inside the base material layer 100, and the water-locking cloth 110 is made of high-absorbency fibers. Specifically, two chambers are provided inside the base material layer 100, and the two chambers are distributed vertically as shown in the Figure 1 direction, and the two chambers are at least connected to one side of the base material layer 100; the water-locking cloth 110 is filled in the two chambers; that is, two layers of water-locking cloth 110 are provided inside the base material layer 100, and the two layers of water-locking cloth 110 are separated from each other.

[0035] The water-locking cloth 110 is mainly used to increase the water-locking performance of the base material layer 100, and the spaced arrangement of the water-locking cloth 110 is to make the locking performance of the base material layer 100 more uniform.

[0036] Further, the base material layer 100 and the water-locking cloth 110 are fixed by hot pressing or by glue, so that when the base material layer 100 is extruded and deformed, the water-locking cloth 110 is still stably installed in the base material layer 100, preventing the water-locking cloth 110 from shifting or falling out of the chamber.

[0037] The metal mesh layer 200 covers at least the upper surface and the lower surface of the base material layer 100. The metal mesh layer 200 enhances the durability of the base material layer 100 and extends the service life of the base material layer 100;

[0038] Further, the metal mesh layer 200 is arranged in multiple layers, and the mesh size on each metal mesh layer from the inside to the outside is distributed in a gradually decreasing structure, which can reduce the entry of dirt or particulate matter into the base material layer 100 and reduce the accumulation of dirt in the base material layer 100.

[0039] Optionally, the metal mesh layer 200 can also extend to the side surface of the base material layer 100;

[0040] Further, the metal mesh layer 200 and the base material layer 100 are fixed by gluing.

[0041] The matte layer 300 covers the metal mesh layer 200 and corresponds to the upper surface and the lower surface of the base material layer 100; the matte layer 300 is provided with bumps 310 protruding away from the base material layer 100, which can enhance its polishing performance.

[0042] In one embodiment, as Figure 2 shown, the bump 310 is rectangular;

[0043] In one embodiment, as Figure 3 shown, the bump 310 is triangular.

[0044] Whether it is rectangular or triangular, the corners of the bump 310 are set as R corners, that is, they have arcs. If it is triangular, the three corners of the triangle are arc-shaped corners. If it is rectangular, the four corners of the rectangle are arc-shaped corners. The R-corner polished product will not cause scratches and make the product glossier.

[0045] The matte layer 300 and the metal mesh layer 200, the base material layer 100 are fixed by gluing.

[0046] In one embodiment, the base material layer 100 is any one of TPU, PE, PET, EVA or cloth base.

[0047] In one embodiment, the substrate layer is a sponge body.

[0048] During use, when the sponge abrasive is used to polish a workpiece, the abrasive layer 300 polishes the surface of the workpiece. The substrate layer 100 and the water-locking cloth 110 can better absorb the polishing liquid and have better retention performance for the polishing liquid, which is beneficial to improving the polishing effect on the workpiece. For the waste chips, particles, etc. generated during the polishing process, due to the blocking effect of the metal mesh, the waste chips, particles, etc. are reduced from being collected in the sponge body 100.

[0049] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
