Abstract

PURPOSE: To simply obtain surface treated calcium carbonate useful as a rubber reinforcing filler by hydrolyzing silicic acid ester coexisting with calcium carbonate and by covering the carbonate with the resulting silicon dioxide.
CONSTITUTION: Heavy or light calcium carbonate and silicic acid ester are allowed to coexist, and the surface of the carbonate is covered with silicon dioxide formed by hydrolyzing the ester in a basic region. In order to accelerate the hydrolysis a basic cpd. is pref. added. With respect to the treating method a method of spryaing a treating soln. contg. silicic acid ester upon calcium carbonate powder and drying the sprayed powder is advantageous in cost. In case of heavy calcium carbonate esp. remarkable rubber reinforcing properties are shown.
