技術摘要: |
本發明提供一種有機/無機複合型分散劑及其應用,可有效分散金屬氧化物奈米粒子。本發明之有機/無機複合型分散劑可為無機黏土及與該無機黏土結合之有機界面活性劑、或無機黏土及與該無機黏土結合之聚醚胺、或聚異丁烯琥珀酸酐(PIB-SA)及與該聚異丁烯琥珀酸酐結合之聚醚胺。將本發明之有機/無機複合型分散劑混合於金屬氧化物奈米粒子中,可使其均勻分散、有效避免粒子之聚集、降低分散液之黏度及提升分散穩定性效果。
The present invention discloses an inorganic/organic mixed component (I/O) dispersant and applications thereof, which is primarily applied to dispersing nanoparticles of metal oxides. The I/O dispersant of the present invention can be a composite of inorganic clay and an organic surfactant, a composite of inorganic clay and polyoxyalkylene-amine, or a composite of inorganic clay, polyisobutylene succinic anhydride (PIB-SA) and hydrochloric acid salt or tetraalkyl quaternary salt of polyoxyalkylene-amine, or fatty amines. By mixing with the I/O dispersant of the present invention, nanoparticles of a metal oxide can be uniformly dispersed without aggregation particularly at high solid content. The dispersion has a lower viscosity and is relatively stable in storage even at high temperature.
