Again carbon black, resin, polypropylene wax, quaternary amine are poured in the mixing roll, evenly mixed, process compound.
Afterwards, above-mentioned compound is dropped in the extruding machine, under 90 ~ 150 ℃ temperature, compound is extruded slabbing, then the sheet compound is cooled off to 40 ~ 45 ℃, and be ground into fragment.
Afterwards, above-mentioned fragment is ground into the flour that particle diameter is 40 ~ 50 μ m.
Afterwards, using fluidized bed air flow crusher is 6 ~ 7kg/m at pressure
3Air under carry out air-flow and pulverize, and carry out classification with 5000 ~ 5500 rev/mins grader, remove particle diameter greater than 16 μ m or less than the flour of 5.04 μ m with drip catcher, obtain the semi-manufacture that mean grain size is 8 ~ 9 μ m.
Again, add silicon dioxide and zinc stearate, mixed 3 ~ 4 minutes, make its flowability greater than 20% with 900 rev/mins stirring machines.
At last, sieve, process the two component electropositivity ink powders of laser printer dry type of the present invention with 200 eye mesh screens.
Adopt above scheme, have the following advantages:
Owing to contain quaternary amine in the used electropositivity ink powder of the laser printer of the present invention raw material, adopt quaternary amine as charge adjusting agent, and the quaternary amine electric weight be high.Owing to added zinc stearate as surface modifier, improved the flowability of electropositivity ink powder, reduced carried charge; Feasible manuscript of printing and image not only blackness are high; Black print is even, clear picture, and no picture and text place does not have bottom ash; And along with the increase of number of copies, the color of picture and text also can thin out, decay.
