PROCESSES FOR PREPARING HYDROPHOBIC INORGANIC OXIDE PIGMENTS |
摘要 |
The present invention provides a treatment method for rendering inorganic oxide particles, such as TiO2 pigment, hydrophobic by predispersing a suitably reactive organohalosilane into an aqueous media, using intensive mixing means (such as a rotor stator emulsifier or inline static mixer) to form a reactive dispersion. When this dispersion is combined with inorganic oxide particles, such as TiO2 pigment, under sufficient agitation, a hydrophobic inorganic oxide can be formed. The oxides formed by the present invention have good mechanical properties, such as dispersibility in nonpolar substance (<i>i.e.</i>, plastics), and they do not degrade physical properties of the pigmented nonpolar substance, such as lacing resistance of thermoplastics.
