Abstract

PURPOSE:To obtain coated talc having excellent dispersibility, pigment characteristics, etc., by dispersing calcined talc in an aq. soln. of a water-soluble hydrolyzable metallic compd. to precipitate a metal oxide or hydroxide over the entire surface of the talc particle and achieve uniform coating. CONSTITUTION:An aq. soln. of a water-soluble hydrolyzable metallic compd. such as titanium sulfate, aluminum chloride, zinc sulfate, ferrous sulfate, cobalt chloride or sodium silicate is prepd. Calcined talc which has been calcined at 500-950 deg.C, is dispersed in this soln. to precipitate a metal hydroxide and/or a metal oxide over the entire surface of the talc particle. The coated talc is recovered by filtration and optionally calcined to obtain coated talc whose surface is completely coated with the metal hydroxide and/or the metal oxide and which is colored, in a desired color such as black, red, yellow, green or blue.

Good shellfish are white in color, but those containing impurities are gray or pale green. It is called talcum because it has a smooth texture. In Japan, it is also called stone penstone because of the use of dense block-like stones.
B-that was amazing. In foreign countries, it is called soapstone because the flakes and powder are mixed into soap.

性や色調等の顔料特性が不満足なものであつブこ　。Traditionally, talc was processed by dispersing Merck in a surfactant-containing aqueous solution, adding a ferric chloride aqueous solution, adjusting the pH to 9.5 with caustic soda, stirring, washing with water, and drying. A method of obtaining a colored processed powder is known (see Japanese Patent Laid-Open No. 54-86633). It is also known to obtain a white extender pigment by mixing titanium oxide and talc and firing the mixture (Japanese Patent Publication No. 53-1.3491
(see publication). However, with these methods, colored talc powder cannot be obtained, but the surface of each talc particle cannot be effectively cut out, and the resulting product has poor pigment properties such as dispersibility and color tone. I'm disappointed in something unsatisfactory.

(It was generally considered difficult to remove substances such as acid and arsenic. Therefore, the present invention has been able to achieve uniform and complete coverage of the entire surface of the talcum coating.) That's a bit of a contradiction.

is defective. If the temperature exceeds 950°C, the original tactile feel of talc will be lost and the hiding power will become excessively strong.
By firing at a temperature exceeding 950°C, the acid groups contained between the talc layers are released, resulting in magnesium silicate h (M9S Ia 0

The pH of the solution is adjusted as a condition for water decomposition, and depending on the case, the pH of the solution is adjusted by heating the solution. Disperse calcined talc in an aqueous solution of the coating reagent, and when the pH of the solution becomes acidic, add an alkali to cause precipitation; when the solution becomes alkaline, add acid to cause precipitation. The temperature may be room temperature, but may be raised to about 100°C.
