Abstract:
     The present invention relates to the preparation method of one kind of new active calcium carbonate used in plastics, rubber, paint and printing ink. New type Al-system coupling agent is used as modifier, organic substance containing O, N, S, P or other atoms with solitary electron pair is used as synegist, and some necessary processing assistant is added. The new active calcium carbonate features its great additive amount, good dispersivity and processability, low water-absorbing rate and oil-absorbing amount, light colour, high thermal stability, simple process technology and low cost.
