Abstract
The invention discloses an active extra-fine grinding calcium carbonate processing method which belongs to the technical calcium carbonate processing field. In the active extra-fine grinding calcium carbonate processing method, stearic acid is used as an activating agent for activating and modifying calcium carbonate. The active extra-fine grinding calcium carbonate produced by using the processing method has the grain size being up to 1.7 mum and has advanced powder fineness. The activating agent modifies inorganic padding, plays a role of bridging an interface of the inorganic material and a high polymer material, improves the compatibility of the inorganic material and the high polymer material, and has the efficacy which can not be matched by singly modifying triple superphosphate and precipitated calcium carbonate.
Description
Technical field
The invention belongs to the technical field of calcium carbonate processing superfine, modification, specifically refer to calcium carbonate powder modification processing treatment.
Background technology
In the inorganic chemicals industry product, calcium carbonate is to belong to the Chemicals that turnout is very big, purposes is extremely wide, the consumption maximum is paper-making industry in the world, next is as weighting agent, strengthening agent, extender, especially for the polyvinyl chloride plastic material products, such as being used for plastic-steel door and window, upper and lower conduit, cable, pipe etc. for plastics.Calcium carbonate also is used as a kind of filler of tackiness agent, seal gum, coating, paint.Water-ground limestone is one take natural calcite as raw material, with its ink powder, reaches certain fineness standard with the method for machinery.It is different that water-ground limestone is pressed particle diameter, is divided into particulate calcium carbonate, micro mist calcium carbonate, fine calcium carbonate, calcium carbonate superfine powder, super fine calcium carbonate.
Summary of the invention
The purpose of this invention is to provide a kind of calcium carbonate active working method, i.e. a kind of active extra-fine grinding calcium carbonate processing method.
The present invention to achieve these goals, the technical scheme that adopts is: a kind of active extra-fine grinding calcium carbonate processing method is provided, and described active extra-fine grinding calcium carbonate processing method uses stearic acid as activator.
Active extra-fine grinding calcium carbonate processing method one preferred version of the present invention: described active extra-fine grinding calcium carbonate complete processing is,
(1) with the calcite of supplied materials less than 400mm, respectively through jaw crusher, hammer crushing crusher machine, the calcite particle diameter that obtains advances storage bin and stores less than 5mm;
(2) through three grades of pulverizing, grading machine classification, classification is not up to standard sends storage bin back to material by storage bin;
(3) classification material up to standard carries out the activator activation modification in the turbine mill.
Active extra-fine grinding calcium carbonate processing method one preferred version of the present invention: described active extra-fine grinding calcium carbonate complete processing turbine mill rotating speed is 3000 rev/mins, and Heating temperature is 100-110 ℃.
Active extra-fine grinding calcium carbonate processing method beneficial effect of the present invention is:
1, the calcite particle diameter after classified can reach 1.7 μ m, and powder fineness is leading.
2, calcium carbonate do super-refinement can improve filled articles snappiness, improve to stretch, impact property.
3, activator modified inorganic filler plays the effect of on inorganic materials and macromolecular material interface " bridge formation ", improves the consistency of inorganic materials and macromolecular material.
4, the active extra-fine grinding calcium carbonate that utilizes working method of the present invention to produce has simple modified heavy calcium carbonate, the simple incomparable effect of modification fine particle calcium carbonate.
Embodiment
Embodiment
A kind of complete processing of using stearic acid to produce active extra-fine grinding calcium carbonate as activator is:
(1) with the calcite of supplied materials less than 400mm, respectively through jaw crusher, hammer crushing crusher machine, the calcite particle diameter that obtains advances storage bin and stores less than 5mm;
(2) through three grades of pulverizing, grading machine classification, classification is not up to standard sends storage bin back to material by storage bin;
(3) classification material up to standard carries out the activator activation modification in the turbine mill, turbine mill rotating speed is 3000 rev/mins, and Heating temperature is 100-110 ℃.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
