Document Type and Number:
Japanese Patent JP2018103342
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polishing material which can achieve high machinability and high durability, and can be suitably used for applications of grinding and polishing of a steel material.SOLUTION: A polishing material contains a porous body obtained by generating a plurality of air bubbles derived a thermally expandable microsphere through a step of mixing thermosetting resin powder containing an epoxy resin having an average particle size of 5-300 μm, the thermally expandable microsphere which contains a volatile component in an outer shell as a foaming agent and can be expanded at a curing temperature of the thermosetting resin powder or lower, and abrasive grains, and heating the mixed substance in a molding die to cure curable resin powder, and abrasive grains dispersed into the porous body.SELECTED DRAWING: None
