Title (EN) FLUORINE-CONTAINING COMPOSITE PARTICLES
(FR) PARTICULES COMPOSITES CONTENANT DU FLUOR
(JA) フッ素含有複合粒子
Abstract:
(EN) Provided are fine particles that can exhibit higher water repellency and higher oil repellency than conventional ones. The present invention pertains to fluorine-containing composite particles obtained by coating the surface of silica fine particles with at least one of 1) a fluorine-containing compound and 2) a fluorine-containing group formed by siloxane bonding between the fluorine-containing compound and silicon in the silica fine particles, wherein (1) the fluorine-containing compound includes a functional group represented by [-Si(OR)3] (wherein, three Rs may be the same or different and each represent hydrogen or a C1-10 alkyl group) at at least one end of the main chain of perfluoropolyether, and (2) the fluorine content per unit surface area of the silica fine particles is 0.8 mg/m2 to 1.0 g/m2.
(FR) L'invention concerne des particules fines qui peuvent présenter un caractère hydrofuge supérieur et un caractère oléofuge supérieur à ceux des particules fines classiques. La présente invention concerne des particules composites contenant du fluor obtenues par revêtement de la surface de particules fines de silice avec au moins l'un de 1) un composé contenant du fluor et 2) un groupe contenant du fluor formé par liaison siloxane entre le composé contenant du fluor et le silicium dans les fines particules de silice, (1) le composé contenant du fluor comprenant un groupe fonctionnel représenté par [-Si(OR)3] (les trois R pouvant être identiques ou différents et représentent chacun un atome d'hydrogène ou un groupe alkyle en C1-10) au niveau d'au moins une extrémité de la chaîne principale de perfluoropolyéther, et (2) la teneur en fluor par unité de surface des particules fines de silice est de 0,8 mg/m2 à 1,0 g/m2.
(JA) 従来よりも高い撥水性及び撥油性を発揮できる微粒子を提供する。 シリカ系微粒子の表面が1)フッ素含有化合物及び2)それがシリカ系微粒子のケイ素とシロキサン結合してなるフッ素含有基の少なくとも1種で被覆されている複合粒子であって、(1)前記フッ素含有化合物が、パーフルオロポリエーテルからなる主鎖の少なくとも一方の末端側に[-Si(OR)](但し、3つのRは、互いに同一又は異なって、水素又は炭素数1~10のアルキル基を示す。)で示される官能基を含む化合物であり、(2)前記シリカ系微粒子の単位表面積当たりのフッ素含有量が0.8mg/m~1.0g/mである、ことを特徴とするフッ素含有複合粒子に係る。
