Abstract
It is ultra-fine with modified processing technology the invention discloses a kind of powdered whiting dry method, comprise the following steps：1) powdered whiting that particle diameter is 200 mesh is chosen, being put into drying chamber carries out drying 4 hours；2) modifying agent stearic acid, calcium stearate, zinc stearate is chosen to be well mixed；3) powdered whiting and modifying agent after drying are put into airslide disintegrating mill to crush, delivery rate is 5-10kg/min, and operating pressure is 0.7-1.0Mpa；4) powdered whiting after crushing is cooled down, screening obtains finished product.Processing technology of the present invention, carries out that dry method is ultra-fine and modification to powdered whiting, calcium carbonate can be changed into functional filler from fillibility filler, improves its dispersiveness in the composite and the compatibility with organic polymer；The technique have simple low production cost, control it is simple and convenient, be adapted to large-scale production, reduce equipment investment, the characteristics of influence factor is few.
Description
Technical field
The present invention relates to the modified processing technique field of powdered whiting, more particularly to a kind of heavy carbon
Sour calcium dry method is ultra-fine with modified processing technology.
Background technology
Calcium carbonate raw material is wide, cheap, non-toxic, easy to use, be domestic and international yield and
One of maximum inorganic filler agent of consumption, mainly as plastics, rubber, coating, paint and
The inserts of the industries such as papermaking.But use common process typically to use wet processing, manufacture
Calcium carbonate has the surface characteristic of hydrophilic oleophobic, can only play increment and filling, and wet method adds
Work not only complex operation, and increase the production cost of modified heavy calcium carbonate.
The content of the invention
The present invention is for above-mentioned calcium carbonate defect problem of the prior art, there is provided a kind of heavy
Calcium carbonate dry method is ultra-fine with modified processing technology, and the processing technology carries out dry method to powdered whiting
Ultra-fine and modification, can be changed into functional filler by calcium carbonate from fillibility filler, improve
Its dispersiveness in the composite and the compatibility with organic polymer；The technique has letter raw
Low cost is produced, simple and convenient, suitable large-scale production is controlled, is reduced equipment investment, influence
The characteristics of factor is few.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of powdered whiting dry method is ultra-fine with modified processing technology, comprises the following steps：
1) powdered whiting that particle diameter is 200 mesh is chosen, being put into drying chamber, to carry out drying 4 small
When；
2) modifying agent stearic acid, calcium stearate, zinc stearate is chosen to be well mixed；
3) powdered whiting and modifying agent after drying are put into airslide disintegrating mill to crush, feed
Speed is 5-10kg/min, and operating pressure is 0.7-1.0Mpa；
4) powdered whiting after crushing is cooled down, screening obtains finished product.
Further, the modifying agent stearic acid, calcium stearate, the mass fraction of zinc stearate
It is the 1-2% of powdered whiting.
Further, the modifying agent stearic acid, calcium stearate, the mass fraction of zinc stearate
It is the 1.5% of powdered whiting.
Further, the stearic acid, calcium stearate, the mass ratio of zinc stearate are 1：1：
1。
Further, the operating pressure of the airslide disintegrating mill is 0.8Mpa.
Beneficial effects of the present invention：A kind of powdered whiting dry method is ultra-fine with modified processing technology,
The processing technology carries out that dry method is ultra-fine and modification to powdered whiting, can be by calcium carbonate from filling out
Filling property filler is changed into functional filler, improve its in the composite dispersiveness and with have
The compatibility of machine high polymer；The technique has simple low production cost, control simple and convenient, suitable
The characteristics of mass producing, reduce equipment investment, influence factor less.
