| description | To provide a porous metal oxide powder capable of suppressing intrusion of a liquid resin into particle pores in mixing with the liquid resin, maintaining large-capacity pores derived from particles formed by primary particles, and imparting high heat insulation property to a resin composition obtained by the mixing, and a method for producing the same.SOLUTION: A porous spherical metal oxide powder has a specific surface area measured by BET method of 400 m2/g or more and 1000 m2/g or less, a pore volume (V: ml) measured by BJH method of 2 ml/g or more and 8 ml/g or less, an oil absorption amount of 90 V+200 ml/100 g or less, and a median diameter in a particle size distribution measured by a laser diffraction method of 2 μm or more and 200 μm or less. The porous spherical metal oxide powder is obtainable by forming a W/O pickering emulsion from a metal oxide aqueous sol, an organic solvent, and a hydrophobic inorganic fine powder, gelatinizing the metal oxide aqueous sol, and then adding a hydrophilic organic solvent and water for demulsification.SELECTED DRAWING: None
【課題】 液状樹脂との混合において、粒子細孔内への上記液状樹脂の浸入を抑制し、一次粒子によって形成された粒子由来の大容量の細孔を維持することができ、上記混合によって得られる樹脂組成物に高い断熱性を付与することが可能な多孔質金属酸化物粉末とその製造方法を提供する。【解決手段】 ＢＥＴ法により測定される比表面積が４００ｍ２／ｇ以上１０００ｍ２／ｇ以下、ＢＪＨ法により測定される細孔容積（Ｖ：ｍｌ）が２ｍｌ／ｇ以上８ｍｌ／ｇ以下、吸油量が９０Ｖ＋２００ｍｌ／１００ｇ以下およびレーザー回折式測定による粒度分布におけるメジアン径が２μｍ以上、２００μｍ以下である多孔質球状金属酸化物粉末であり、金属酸化物水性ゾル、有機溶媒及び疎水性無機微粉末よりＷ／Ｏピッカリングエマルジョンを形成した後に、金属酸化物水性ゾルをゲル化させ、次いで、親水性有機溶媒と水を添加して解乳することにより得ることができる。【選択図】 なし |
