Abstract:
1. A method for manufacturing an elastic abrasive comprising: preparing a core by granulating a crosslinked polyrotaxane compound having a rubber hardness of 30 or less and having autohesion properties so as to have a predetermined grain diameter, and after sprinkling abrasive grains having an average grain diameter of 0.1 μm to 12 μm on the surface of the core, applying a pressing force to the surface of the core having the abrasive grains sprinkled thereto to fix the abrasive grains on the surface of the core, and forming an abrasive-grain layer having a masonry structure formed by integrally forming multiple abrasive grains in the thickness direction on the surface of the core by repeating similar fixation by sprinkling abrasive grains and applying a pressing force on the surface of the core having the abrasive grains fixed thereon.
