A grinding material product with a concave-convex structure and a preparation method of the grinding material product. When being used for cleaning an LCD liquid crystal panel, the grinding material product with a concave-convex structure has advantages of a continuous and stable cutting force, no scratch on a glass substrate, a long service life, and the like. The grinding material product with a concave-convex structure is characterized by comprising three laminated planar structure layers and grinding material layers with concave-convex structures located on upper surfaces of the three planar structure layers, the grinding material layers with concave-convex structures are grinding material block arrays, a ditch groove is arranged between one grinding material block in the grinding material block array and any adjacent grinding material block, the ditch groove is a chip groove, and the grinding material block comprises an adhesive and abrasive grains distributed in the adhesive. |
