ものである。Phenolic resin, which is the main component of the abrasive of the present invention, is one of the most rigid resins among the resins, and because of its good binding force with the reinforcing material and the filler, it has a grinding wheel, a friction material, and a refractory material. It is used as a binder for shell molds and the like. That is, although phenolic resin has high rigidity and high mechanical strength among thermosetting resins for abrasives, the objects to be abraded have been diversified recently, and an abrasive having both abrasivity and flexibility is required. ing. The abrasive of the present invention is a cured product of a composition containing a phenol resin and a glass filler as essential components, has a high hardness as high as glass, and has the rigidity and strength of the phenol resin added thereto.

The spherical glass and crushed powder glass can have various particle sizes, but preferably 300 μm or less. It is preferable that the single fiber glass has a diameter of 30 μm or less and a length of 5 mm or less. Spherical glass is used for abrasives with good polishing power and durability, crushed powdered glass is used for abrasives that require particularly high polishing power, and single fiber glass is used for abrasives that require more flexibility. And exhibits excellent characteristics.

The content of the phenolic resin is 20 to 70% by weight, but if it is less than 20% by weight, the bonding strength of the cured product is lowered, so that the durability is insufficient and the polishing power is lowered, and if it exceeds 70% by weight, the filling is completed. The effect of blending materials, especially glass filler, becomes insufficient. The content of the glass filler is 30 to 80% by weight, but if it is less than 30% by weight, the effect of compounding the glass filler is small, and if it exceeds 80% by weight, the binding force by the phenol resin is decreased. When a filler other than glass is blended, glass or part of the glass and phenol resin is replaced with the filler. The amount thereof is preferably 1 to 25% by weight from the viewpoint of abrasive material characteristics, that is, abrasiveness and flexibility.
