摘要:
An abrasive that can impart a mirror finish, glossiness, or the like to a surface of a workpiece by blasting is provided. A crosslinked polyrotaxane compound having a network structure where crosslinking points are circular molecules of polyrotaxane and also having abrasive grains dispersedly mixed therein is obtained by causing chemical bonding between the circular molecules of the polyrotaxane in a state where the abrasive grains and the polyrotaxane are mixed. Then, the crosslinked polyrotaxane compound is granulated to a predetermined grain diameter to obtain a gel-like abrasive where a part of the dispersedly mixed abrasive grain is exposed at the surface. By using the thus-obtained gel-like abrasive in blasting by projecting the abrasive at an angle tilted with respect to a surface of a workpiece, mirror finishing or the like is possible without making the surface of the workpiece pearskin-like.
