Abrasive, abrasive article and the method for preparing the same

Abstract

An abrasive comprising abrasive particles and an adhesive matrix is provided, with the abrasive particles being distributed in the adhesive matrix, wherein the abrasive particles comprise aluminum hydroxide abrasive particles, and the adhesive matrix comprises a triacrylate, a diacrylate and an initiator. The abrasive article prepared using the abrasive of the present invention has proper wear resistance and can be used to a clean LCD panel surface without scratching the ITO coating on an LCD panel surface.
