Abstract

PURPOSE: To prepare calcium carbonate having improved dispersibility in polyolefin, whiteness, and reinforcing characteristics, etc., by adding an alkylnaphthalenesulfonic acid and a higher fatty acid to a suspension of cubic calcium carbonate, and treating the mixture.
CONSTITUTION: An aqueous suspension of cubic calcium carbonate particles having an average particle diameter of 0.1W0.5μ is added and adsorbed with (A) an alkylnaphthalenesulfonic acid (salt) and/or an alkylbenzenesulfonic acid (salt) and (B) one or more higher fatty acids (or salts) having an iodine value of ≤20. The suspension is dehydrated, dried, crushed, and classified to a desired grain size. 20W 80pts.wt. of the surface-treated calcium carbonate thus obtained is dispersed in 100pts.wt. of a polyolefin resin. The modified calcium carbonate has excellent dispersibility, and gives a plastic with excellent physical properties such as whiteness, gloss, impact strength, etc.
