METHOD FOR PRODUCING ELASTIC GRINDING MATERIAL, ELASTIC GRINDING MATERIAL, AND BLASTING METHOD USING SAID ELASTIC GRINDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/094492
Kind Code:
A1
Abstract:
A long-lasting elastic grinding material capable of subjecting surfaces of objects to mirror-finishing, glossifying and the like via blasting thereof. A nucleus (2) is obtained by granulating a crosslinked polyrotaxane compound having self-tackiness and a rubber hardness of 30 or less into particles of a prescribed diameter. The nucleus (2), which is soft and exhibits significant deformability, is sealed on the inside of an abrasive-particle layer (3) by: adhering abrasive particles (31) to the surface of the nucleus (2); then affixing the abrasive particles (31) to the surface of the nucleus (2) by applying pressure to the surface of the nucleus (2) to which the abrasive particles (31) are adhered; and forming the abrasive-particle layer (3), which has a masonry-like structure formed by attaching a plurality of the abrasive particles (31) in the thickness direction to the surface of the nucleus (2), by further subjecting the surface of the nucleus (2) to which the abrasive particles (31) are affixed to repeated adhesion of identical abrasive particles (31) and affixing by application of pressure.
