Abstract
The invention provides a kind of preparation method of composite calcium carbonate, the composite calcium carbonate is prepared by the raw material of following parts by weight：30 60 parts of nano level light calcium carbonate, 10 30 parts of powdered whiting, 5 15 parts of silane coupler；The preparation method of the composite calcium carbonate is：After nano level light calcium carbonate and powdered whiting are prepared by proportioning, it is sent in high-speed mixer, then adds silane coupler, composite calcium carbonate finished product is obtained after mixing 20 30min.On the one hand there are the partial properties of nano level light calcium carbonate, the partial properties on the other hand also with powdered whiting, obtained composite calcium carbonate has high dispersive, the superior function of low oil absorption ferric.
Description
Technical field
The invention belongs to calcium carbonate preparing technical field, and in particular to a kind of preparation method of composite calcium carbonate.
Background technology
In the last few years, it is that macromolecule is compound as expanding economy, the application of precipitated calcium carbonate are further developed
A kind of inorganic filler being most widely used in material, is widely used in rubber, plastics, paper, coating, adhesive, ink, electricity
In the industries such as cable, although because precipitated calcium carbonate is that performance in some respects is made by chemical method to be better than by physics side
Powdered whiting made from method, but again not as good as powdered whiting in terms of having, the lightweight carbon that our in the markets are produced
The dispersive property of sour calcium is more than the dispersive property of powdered whiting, and oil absorbency is less than the oil absorbency of powdered whiting
This develops a kind of composite calcium carbonate and solves the problem.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of preparation method of composite calcium carbonate, specific skill
Art scheme is：A kind of preparation method of composite calcium carbonate, the composite calcium carbonate are prepared by the raw material of following parts by weight：
Nano level light calcium carbonate 30-60 parts, powdered whiting 10-30 parts, silane coupler 5-15 parts；The composite carbon
The preparation method of sour calcium is：After nano level light calcium carbonate and powdered whiting are prepared by proportioning, it is sent to mixed at a high speed
In conjunction machine, silane coupler is then added, composite calcium carbonate finished product is obtained after mixing 20-30min.
Further, the rotating speed of the mixer is 300-800r/min, and the temperature in mixer is 50-80 DEG C.
Further, the preparation method of the nano level light calcium carbonate is：It is molten to the calcium hydroxide that concentration is 10-20%
The kiln gas of carbonated 35% is passed through in liquid, calcium hydroxide is carbonized, then filters, dry, crushing obtains nanoscale
Precipitated calcium carbonate.
Further, the dispersant in the carburising step added with 5-10 parts and the defoamer of 3-8 parts.
Further, the dispersant is polycarboxylic acid dispersant.
Further, the defoamer is the aqueous defoamer being made up of dimethicone, white carbon, emulsifying agent.
Beneficial effect：The invention provides a kind of preparation method of composite calcium carbonate, the present invention uses nanoscale lightweight carbon
Sour calcium mixes with powdered whiting to be made by silane coupler modified, on the one hand with the partial of nano level light calcium carbonate
Can, on the other hand also have powdered whiting partial properties, obtained composite calcium carbonate have high dispersive, low oil absorption ferric it is excellent
More performance, the calcium carbonate of low oil absorption ferric are added to the dosage that plasticizer can be reduced in plastics, can also increase adding for calcium carbonate
Dosage reduces the cost of plastic product, improves the mechanical property of plastic products；Dispersant is with the addition of in carbonizatin method preparation process
The dispersive property of finished product nano level light calcium carbonate is ensure that with defoamer.
