| description | PROBLEM TO BE SOLVED: To provide composite particles which enable mirror polishing by flow machining, can be used over a long period of time, have less time degradation of performance, and are mainly used as abrasive grains, and to provide a method for producing the same.SOLUTION: Composite particles include a plurality of particles formed of a material having new Mohs hardness of 13 or more and a resin containing polyvinyl alcohol. The material having the new Mohs hardness of 13 or more is preferably silicon carbide, and the resin preferably contains an elastomer. A production method includes: a first step of dispersing powder formed of a material having new Mohs hardness of 13 or more into an aqueous solution containing polyvinyl alcohol and alkali metal salt of an alginic acid; a second step of bringing the dispersion obtained in the first step in contact with an aqueous solution containing a cation-containing compound; and a third step of drying a molding obtained by the second step.SELECTED DRAWING: Figure 1
【課題】本発明の目的は、流動加工による鏡面研磨が可能で、かつ長期にわたって使用することができるとともに、性能の経時劣化も少ない、主に砥粒として用いられる複合粒子及びその製造方法を提供することである。【解決手段】本発明の複合粒子は、新モース硬度が１３以上の材料からなる複数の粒子と、ポリビニルアルコールを含む樹脂から構成されていることを特徴とする。新モース硬度が１３以上の材料は炭化ケイ素であることが好ましく、その樹脂はエラストマーを含むことが好ましい。また、本発明の製造方法は、新モース硬度が１３以上の材料からなる粉体をポリビニルアルコールとアルギン酸のアルカリ金属塩を含む水溶液中に分散させる第一の工程と、第一の工程によって得られた分散液をカチオン含有化合物を含む水溶液に接触させる第二の工程と、第二の工程によって得られた成形物を乾燥させる第三の工程を含むことを特徴とする。【選択図】図１ |
