Method for producing composite pigment |
| abstract |
(57) [Abstract] [Objective] A method for producing a composite pigment, particularly a composite pigment from titanium dioxide and calcium sulfate. [Composition] An aqueous dispersion of granular calcium sulfate is formed, The dispersion is pulverized to give an average particle size of calcium sulfate of 10 less than μ, preferably less than 5 μ, and finely ground calcium sulfate is mixed with pigmentary titanium dioxide to form an aqueous dispersion of mixed particles of titanium dioxide and calcium sulfate, It is produced by coating the mixed particles with an oxide or hydrated oxide of metal or silicon. This composite pigment exhibits improved optical properties when used in coating compositions such as paints over simple mixtures of titanium dioxide and calcium sulfate. |
