沢鏡面を形成する。On the other hand, cerium oxide is known for use as described above or as an abrasive for final polishing of precision ultra-thin glass such as flat display glass, magneto-optical disks, and CCD cover glasses. This cerium oxide abrasive has a Mohs hardness of 6 and is characterized by being softer than abrasives such as diamond and silicon carbide. Before use, the particle size of the cerium oxide abrasive is mainly submicron, and it is well suspended in water, and this water acts as a grinding aid. Also, cerium oxide causes mechanical destruction by itself during polishing, and becomes fine powder. This creates a glossy mirror surface while polishing the surface of the workpiece without damaging it.

とである。従って、酸化珪素研磨材のようにペースト状

て使用すると、研磨後はペーストを洗い流すことから、
ペーストが無駄になり、不経済となるものであった。As described above, cerium oxide abrasives have many features not found elsewhere, but the drawback is that they are expensive. Therefore, when using a paste like silicon oxide abrasive, for example, if you sprinkle this paste on cloth etc., the paste will be washed away after polishing.
The paste was wasted and was uneconomical.
本発明は上記した現状に鑑み、高価な酸化セリウム研磨
材を有効に利用でき、しかも研磨に際して効率の良い研
磨部材を提供することを目的とするものである。In view of the above-mentioned current situation, it is an object of the present invention to provide a polishing member that can effectively utilize an expensive cerium oxide polishing material and is highly efficient in polishing.
本発明は、酸化セリウム研磨材を繊維で強化された多孔
ウレタン樹脂に固定した研磨布により、前記課題を遠戚
したものである。The present invention is a distant relative of the above problem by providing an abrasive cloth in which a cerium oxide abrasive material is fixed to a porous urethane resin reinforced with fibers.

易に洗い流せ、何回でも繰返して使用できる。In the present invention, since the cerium oxide abrasive material is fixed to the porous urethane resin, the cerium oxide abrasive material is firmly supported by the resin, and the cerium oxide inside also participates in polishing. Furthermore, by soaking in water before use, moisture is sufficiently removed from the resin pores. This water acts as a polishing aid (slip material) during polishing, and since the porous resin to which cerium oxide is fixed is reinforced with fibers, it maintains the flexibility of the fibers while increasing its strength. The polishing cloth has improved polishing properties, and the workpiece (dust) attached to the polishing cloth can be easily washed away with detergent, allowing it to be used over and over again.
以下に本発明の実施例を図面を参照して説明する。Embodiments of the present invention will be described below with reference to the drawings.

The urethane resin contains 5 to 75% by weight of particles having an average particle size of 1 μm or less and a maximum particle size of 5 μm or less. 2 is a porous urethane resin, and the above-mentioned cerium oxide abrasive material is fixed to this porous urethane resin 2. When the porous urethane resin 2 is fixed on the cerium oxide abrasive material, the foaming conditions are controlled to the optimum relationship between the abrasive particle diameter and the bubble diameter, and the bubbles are filled with water, which is an auxiliary material during the polishing process. Those that can be retained by capillary action, specifically, the bubble diameter is controlled to 100 μm or less during the foaming process, and the bubbles are opened and open. 3 is a fiber reinforcing the porous urethane resin 2 to which the cerium oxide abrasive material 1 is fixed, and is a nonwoven fabric or other base fabric suitable for polishing, specifically polyester, nylon, rayon, acrylic, polypropylene, cotton, etc. is suitable.
