Description

A kind of processing technique of modified calcium carbonate
Technical field
The present invention relates to calcium carbonate production and processing technical field, particularly relate to the processing technique of a kind of modified calcium carbonate.
Background technology
Calcium carbonate can play a kind of skeleton function as Chinese white in coating, and inserting of calcium carbonate can strengthen priming paint Deposition and permeability to substrate surface.Currently, the calcium carbonate of the production such as day raw white stone company, Lyceum company of Italy is main It is applicable to improve the serviceability of water paint.But, the hydrophilic oleophobic of calcium carbonate surface, in highly polar, difficult in organic media With dispersed, poor with the adhesion of base material, easily cause boundary defect, cause material property to decline；Calcium carbonate particle particle diameter is more Little, the atomic number on surface is the most, and surface can be the highest, and adsorption is the strongest, is in thermodynamics unsteady state, between each particle easily Reunite mutually, it is impossible to well disperse in polymeric matrix.Live in the miniaturization of calcium carbonate particle, the complication of structure, surface Property is the main development direction of calcium carbonate industry from now on.
Summary of the invention
The problem that the present invention is directed to above-mentioned calcium carbonate, it is provided that the processing technique of a kind of modified calcium carbonate, this processing technique is led to Cross and calcium carbonate and modifying agent titanate coupling agent, stearic acid are carried out activation modification process in high-speed mixer, activated Degree is high, the powder hydrophobic calcium carbonate of good dispersion.
For achieving the above object, the technical solution used in the present invention is:
The processing technique of a kind of modified calcium carbonate, comprises the following steps:
S1, choose calcium carbonate 90-110 part, titanate coupling agent 1.5-2.5 part, stearic acid 2-3 part according to mass parts；
S2, putting in high-speed mixer by calcium carbonate, heated up mixing, treats that temperature reaches 100 DEG C, except water 5-10 minute；
S3, titanate coupling agent is put in high-speed mixer, be 110-130 DEG C in temperature, activation processing calcium carbonate 5-10 minute, add stearic acid modified process 10-20 minute；
S4, by modified calcium carbonate at 110 DEG C of discharge high-speed mixers, cooling, obtain activation grade high, good dispersion Powder hydrophobic calcium carbonate.
Further, calcium carbonate 100 parts, titanate coupling agent 2 parts, stearic acid 2.5 parts in described S1.
Further, in described S1, titanate coupling agent is chelating titanate coupling agent KR-201.
Further, calcium carbonate mesh number described in described S1 is 2000 mesh.
Further, described S3 high-speed mixer rotating speed is 2000-3000r/min.
Beneficial effects of the present invention: the processing technique of a kind of modified calcium carbonate, this processing technique by by calcium carbonate with change Property agent titanate coupling agent, stearic acid in high-speed mixer, carry out activation modification process, obtain activation grade high, good dispersion Powder hydrophobic calcium carbonate；After modification, calcium carbonate dispersibility is improved, and calcium carbonate surface is hydrophobicity, has good Adsorptivity.
