Preparation method of powdered ink suitable for aluminum developing roller

Abstract

The invention relates to a preparation method of powdered ink suitable for an aluminum developing roller. The preparation method of the powdered ink suitable for the aluminum developing roller comprises the following steps of mixing 85-90% of polyester resin, 2-5% of PP wax, 0.5-2% of PE wax, 0.5-3% of ferrous series complex and 5-10% of nanometer carbon black in a high-speed mixing machine according to mass proportion of each constituent; performing melt extrusion and smashing after rolling; performing fine smashing, wherein the obtained material is a powdered ink half-finished product; mixing modified silicon dioxide, modified nanometer ferric oxide, nanometer aluminum oxide and silicon dioxide in the mixing machine according to the mass ratios of the modified silicon dioxide, the modified nanometer ferric oxide, the nanometer aluminum oxide and the silicon dioxide respectively accounting for 0.5-2%, 0.3-1%, 0.05-0.3% and 0.3-0.8% of the powdered ink half-finished product; and screening the obtained mixture with a vibration screen, wherein the obtained powdered ink is a powered ink qualified product. The preparation method of the powdered ink suitable for the aluminum developing roller, provided by the invention, is simple in step, and the obtained powdered ink is relatively high in live-line stability, long in storage cycle and more stable in quality.

Description

technical field [0001] The invention relates to a method for preparing toner, in particular to a method for preparing toner suitable for aluminum developing rollers. Background technique [0002] In the development technology, most of the toner development technology is completed by matching the magnetic developing roller with the magnetic toner or matching the rubber developing roller with the non-magnetic toner. Nowadays, because aluminum has good ductility and conductivity, and can be recycled and reprocessed, there is currently a matching development method of aluminum developing roller and non-magnetic toner. [0003] In order to cope with this technological innovation, toner manufacturing mainly uses silicon dioxide to ensure the stability of its charge at present, and silicon dioxide with a general particle size is easy to fall into the recess of the toner, and cannot achieve the isolation effect on the toner , so that the charging stability of the toner is not enoug...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the embodiments of the present invention is that the charging stability of the toner suitable for the aluminum developing roller is not strong, the electrostatic charge generated by the friction of the toner is uneven during use, and the bottom dust is prone to appear during the printing process. The storage period of toner is short, and a method for preparing toner suitable for aluminum developing rollers is proposed
