Abstract
The invention discloses a method for processing coupled superfinely ground and heavy calcium carbonates, which belongs to the field of calcium carbonate processing. The method for processing the coupled superfinely ground and heavy calcium carbonates uses a borate ester coupling agent to activate and modify the calcium carbonates. The particle size of the coupled superfinely ground and heavy calcium carbonates produced by the method can reach 1.7 micrometers, and the powder fineness is higher than before. A coupling agent modified inorganic filler plays a role in 'bridging' an interface of an inorganic material and a high polymer material and improves the compatibility of the inorganic material with the high polymer material. The coupled superfinely ground and heavy calcium carbonates produced by the method can be used as a filling agent in PVC plastic-steel windows and doors, wires and cables, and the processability and the physical and mechanical performance of a finished product of the coupled superfinely ground and heavy calcium carbonates are obviously better that those of generally ground powder and stearic acid modified powder.
Description
Technical field
The invention belongs to the lime carbonate manufacture field, concrete is calcium carbonate superfineization, modification field, i.e. the working method of coupling extra-fine grinding water-ground limestone.
Background technology
In the inorganic chemicals industry product, lime 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 to be used for plastics as weighting agent, strengthening agent, extender, especially for the polyvinyl chloride plastic material products, for example is used for plastic-steel door and window, upper and lower conduit, cable, pipe etc.Lime carbonate also is used as a kind of filler of tackiness agent, seal gum, coating, paint.Water-ground limestone is one to be raw material with natural calcite, with its ink powder, reaches certain fineness standard with the method for machinery.Water-ground limestone is pressed the particle diameter difference, is divided into particulate lime carbonate, micro mist lime carbonate, fine calcium carbonate, calcium carbonate superfine powder, super fine calcium carbonate.
Summary of the invention
The purpose of this invention is to provide the active working method of a kind of lime carbonate, promptly a kind of method for processing coupled superfinely ground and heavy calcium carbonates.
The present invention to achieve these goals, the technical scheme that is adopted is: a kind of method for processing coupled superfinely ground and heavy calcium carbonates is provided, and described method for processing coupled superfinely ground and heavy calcium carbonates uses boric acid ester coupler.
A kind of method for processing coupled superfinely ground and heavy calcium carbonates one preferred version of the present invention: described coupling extra-fine grinding water-ground limestone 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 coupling agent activation modification in the turbine mill.
A kind of method for processing coupled superfinely ground and heavy calcium carbonates one preferred version of the present invention: described coupling extra-fine grinding water-ground limestone complete processing turbine mill rotating speed is 3000 rev/mins, and Heating temperature is 100 1 110 ℃.
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, lime carbonate do super-refinement can improve filled articles snappiness, improve to stretch, impact property.
3, the effect of on inorganic materials and macromolecular material interface " bridge formation " is played in coupling agent modified mineral filler, improves the consistency of inorganic materials and macromolecular material.
4, the coupling extra-fine grinding water-ground limestone that utilizes working method of the present invention to produce can be applied to the PVC plastic-steel door and window, electric wire uses as weighting agent, and its processing characteristics and finished product physical and mechanical properties are apparently higher than common flour abrasive dust and stearic acid modified powder.
