▎ 摘　　要

NOVELTY - Preparing calcium carbonate complex particles comprises (i) pulping, (ii) carbonizing, (iii) treatment agent, (iv) secondary carbonizing, (v) drying the finished product. The calcium carbonate complex particle comprises 50-80 pts. wt. quicklime, 2-5 pts. wt. crystal form control agent, 1-2 pts. wt. graphene, 0.5-1 pts. wt. chitosan, 1-2 pts. wt. glass fiber, 1-2 pts. wt. sodium stearate, 1-2 pts. wt. aluminum silicate, 1-2 pts. wt. 2-propenyl propylene, and 1-2 pts. wt. styrene-acrylic emulsion, and auxiliary material comprising carbon dioxide, methanol or ethanol solution, and water. USE - The method is useful for preparing calcium carbonate complex particles. ADVANTAGE - The method is simple; has excellent effect, and wide application range, and effectively solves the shortcomings of the prior art.
