Research on Preparation of Heavy Calcium Carbonate Functional Filler with Mechanical Chemical Methods

Abstract:

Ultra-fine heavy calcium carbonate functional filler was prepared by aluminum titanium complex coupling agent with mechanical chemical methods and characterized by IR and SEM. The results show that the optimum conditions of mechanical chemistry preparation of heavy calcium carbonate functional filler: the modifier dosage is 1% (mass fraction), the milling time is 2.5h, and grinding ball ratio is 35:45. Under the optimal conditions, the activated degree of heavy calcium carbonate is 99.5%, the particle size of D₅₀ is 4.56μm, and D₉₀ is 9.72μm. FIR and SEM analysis show that the surface of modified heavy calcium carbonate has been coated aluminum and titanium complex coupling agent.
