Surface-fluorinated metal oxide particulates, process for manufacturing the same and use of the same |
摘要 |
A surface-fluorinated metal oxide particulate comprising a metal oxide particulate selected from titanium, aluminum, silicon, silver, copper, zirconium, zinc, tin, germanium, tantalum and the like, being reacted with fluorine and a process for manufacturing such surface-treated metal oxide particulates are disclosed. The process allows easy and efficient fluorination of the surface of metal oxide particulates in any desired ratio. The surface-fluorinated metal oxide particulates of the present invention are useful as an additive for weatherable paints, weatherable resins, cosmetics and the like. Surface-fluorinated titanium oxide particulates obtained by fluorination of titanium oxide particulates have improved light stability, water-repellence, and dispersibility as compared with conventional titanium oxide particulates and maintains surface smoothness of the resin-coated substrate when contained in high concentrations in thermoplastic resins as a white pigment with water content being controlled in a specified range and prevents the occurrence of troubles at the time of melt extrusion coating for obtaining resin-coated substrates. |
