GRINDING MATERIAL PRODUCT WITH CONCAVE-CONVEX STRUCTURE AND PREPARATION METHOD THEREOF

摘要

An abrasive product with a concave-convex structure and preparation method thereof. When being used for cleaning an LCD liquid crystal panel, the abrasive product with a concave-convex structure has advantages of a continuous and stable cutting force and a long service life, without causing scratch on a glass substrate. The abrasive product with a concave-convex structure comprises laminated three planar layers and an abrasive layer with a concave-convex structures located on an upper surface of the three planar layers. The abrasive layer with a concave-convex structure is an array of abrasive blocks, and a groove serving as chips discharging groove is formed between each two adjacent abrasive blocks. The abrasive block comprises a binder and abrasive grains distributed therein.
