A method of modifying calcium carbonate particles was investigated by coating sodium stearate or sodium oleate on the surface of calcium carbonate by wet method. The results of FTIR, activation and dispersion index, dispersity in kerosene, surface wettability tests and zeta potential tests show that sodium stearate or sodium oleate has successfully coated on the surfaces of calcium carbonate. The main factors were researched and the optimal parameters were obtained for the best modification effect. Compared with common rubber, the modified calcium carbonate added rubber has larger breaking tensile strength (more than 21%) and larger elongation at break (more than 16%). This research provides a feasible way of modifying calcium carbonate for its use as filler in organic matrix, reduces the cost and has a potential application in large-scale production of modified calcium carbonate.
