Abstract
The invention relates to a method for producing magnetic black powder through a physical method. The magnetic black powder comprises the following components in parts by weight: 30-70 parts of resin, 25-60 parts of magnetic powder, 0.1-10 parts of a colouring agent, 2-10 parts of paraffin, 0.1-4 parts of a charge agent, 0.1-10 parts of alkaline earth metal oxide, and 3-50 parts of an external additive. The method comprises the following steps: filling 30-70 parts of the resin, 25-60 parts of the magnetic powder, 0.1-10 parts of the colouring agent, 2-10 parts of the paraffin, 0.1-4 parts of the charge agent and 0.1-10 parts of the alkaline earth metal oxide into a raw material mixing machine, sufficiently mixing for 10-30 min, preparing into a sheet through a mixing mill, crushing and grading to obtain a graded product, wherein the particle size of the graded product is 5-14 microns, finally, adding 3-50 parts of the external additive, sufficiently mixing through a high-speed mixing machine for 3-30 min, and filtering by using a 30-100-mesh sieve. On the premise that the quality is ensured, the cost can be greatly reduced.
Description
Technical field
The invention belongs to the production method of black powder, particularly the method for the black powder of a kind of Physical production magnetic.
Background of invention
At present, the manufacturer of the black powder of the magnetic for laser printer is numerous, on most type, its product can meet the basic demand of terminal client in blackness, bottom ash, image level, resolution, sticky bulging, fixing, mobility, environmental suitability, storage, transport etc.But because the cost of raw material is high, cause the cost of product high.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides the method for the black powder of a kind of Physical production magnetic.Under the prerequisite of ensuring the quality of products, can significantly reduce costs.
The present invention solves the technical scheme that its technical matters takes: resin 30-70 part, magnetic 25-60 part, colorant 0.1-10 part, paraffin 2-10 part, charged dose of 0.1-4 part, alkaline earth oxide 0.1-10 part and adjuvant 3-50 part; Its production method is: by the resin of described weight portion, magnetic, colorant, paraffin, charged dose, alkaline earth oxide charging feedstock mixer, abundant mixing 10-30 minute, sheet is made through mixing roll, classification product are obtained after crushing and classification, superfine product particle size is divided to be 5-14 micron, finally add the adjuvant of described weight portion, fully mix 3-30 minute through high-speed mixer, with 30-100 object screen filtration.
The present invention has following advantages: 1), technique is simple; 2), under the prerequisite of ensuring the quality of products, can significantly reduce costs.
