| titleOfInvention | Preparation method of flake-shaped aragonite calcium carbonate |
| abstract | The invention discloses a preparation method of flake-shaped aragonite calcium carbonate. The preparation method comprises the following steps: (1) performing dry method coarse grinding to a shell raw material, soaking the shell raw material in lotion for 4-48h at normal temperature, utilizing roller watering to remove a cuticle layer and a prismatic layer, and obtaining nacreous layer calcium carbonate by washing; (2) adding water to the nacreous layer calcium carbonate, performing high-speed agitation to prepare slurry with the concentration to be 30-80wt%, adding a grinding aid with the weight being 0.5-5% that of the nacreous layer calcium carbonate, and using a stripping machine to perform wet grinding for 60-180min with zirconia ball, alumina balls or ceramic balls serving as grinding mediums; and (3) performing filter pressing and drying grinding to obtain the flake-shaped aragonite calcium carbonate. The preparation method of the flake-shaped aragonite calcium carbonate is simple in process and does not use a poisonous harmful reagent, the operation conditions are mild, the surface activity of the prepared flake-shaped aragonite calcium carbonate is good, and the flake-shaped aragonite calcium carbonate can be widely applied to industries such as plastics, papermaking, rubber, ink, coating, building materials, medicines and food. |
