    MANUFACTURING METHOD OF POROUS CERAMIC PARTICLES WITH COATED SURFACE, AND MANUFACTURING METHOD OF COMPOSITE MATERIAL AND INSULATION MATERIAL USING THE SAME

    New search for: HASHIBA TOMOHIKO

    PROBLEM TO BE SOLVED: To provide a stable manufacturing method of porous ceramic particles with a coated surface, including one step process only, causing no adhesion of particles to each other.SOLUTION: To a mixture solution of porous ceramic particles and a reductant injected into air from a nozzle tip, a coating liquid including a metal salt or a mixture solution of a metal salt and an organic material supplied from a flow channel different from that of the mixture solution of the porous ceramic particles and the reductant is sprayed. Further, to the mixture solution of the porous ceramic particles and the reductant sprayed with the coating liquid, a gas is sprayed so that a solvent is instantly dried. The porous ceramic particles with a coated surface are thus manufactured. The porous ceramic particles with a coated surface obtained by the method are mixed with and dispersed in an epoxy resin so as to manufacture a composite material and an insulation material.

    【課題】１段階の工程で、粒子同士がくっついてしまうことなく安定して多孔質セラミック表面コーティング粒子を製造できる方法を提供する。【解決手段】ノズル先端から空中に噴射された多孔質セラミック粒子と還元剤との混合溶液に、当該多孔質セラミック粒子と還元剤との混合溶液とは別の流路から供給された金属塩若しくは金属塩と有機材料との混合溶液からなるコーティング液を噴きつけ、かつ、コーティング液が噴きつけられた多孔質セラミック粒子と還元剤との混合溶液にガスを噴きつけて溶媒を瞬時に乾燥させる、多孔質セラミック表面コーティング粒子の製造方法、ならびに、当該方法で得られた多孔質セラミック表面コーティング粒子を、エポキシ樹脂と混合分散させる、複合材料及び絶縁材の製造方法。【選択図】図１
