For raw material, the aqueous sodium carbonate that concentration is 0.3~0.8mol/L is configured to water；Using calcium chloride as raw material, absolute ethyl alcohol is used
The calcium chloride alcoholic solution that concentration is 0.3~0.8mol/L is configured to, then aqueous sodium carbonate and calcium chloride alcoholic solution is distinguished
Purification by filtration, then calcium chloride alcoholic solution is slowly added into aqueous sodium carbonate, the addition of calcium chloride alcoholic solution presses chlorination
The molal quantity of the molal quantity: sodium carbonate of calcium is 1: 1~1.1 meters, enters water-filling/alcoholic solution 0.5~2h of interfacial reaction, and generation is precipitated
Centrifugation, and with after redistilled water and absolute ethyl alcohol alternately washing, in being dried at 95~105 DEG C, obtain tangerine flap calcium carbonate micro-
Grain.
The present invention further technical scheme be：Purification by filtration is to lead to aqueous sodium carbonate and calcium chloride alcoholic solution respectively
Cross 0.45 μm of membrane filtration purifying.
Calcium chloride alcoholic solution is added in aqueous sodium carbonate, it is desirable to which calcium chloride alcoholic solution need to be slowly added to, and keeps chlorination
Calcium alcoholic solution is stable to float over aqueous sodium carbonate upper strata, carries out follow-up interfacial reaction until reaction terminates.
The present invention has synthesized tangerine flap calcium carbonate microparticle first, and product morphology is unique, and particle size is at 3 ~ 6 μm, and distribution is equal
It is even.And present invention process method is simple to operate, raw material environmental protection, safety non-toxic.
