Abstract

The invention provides a nonmagnetic negative electricity laser printer ink powder. A styrene-acrylic acid copolymer is selected as an adhesive resin, a carbon black is selected as a pigment, zinc salicylate is selected as a charge conditioning agent, low molecular poly propylene wax is selected as an inner additive, and hydrophobic silica is selected as an external additive. The weight percentage of each component is as follows: 78-90% of adhesive resin, 3-9% of pigment, 2.1-8% of charge conditioning agent, 0.4-2.8% of inner additive and 0.1-4% of external additive. The styrene-acrylic acid copolymer is selected as the adhesive resin, so that two different ingredients are contained, thereby improving performance index of the ink powder, simplifying production technology, and reducing cost. Furtherly, hydrophobic degree of the hydrophobic silica can be controlled, thereby preventing influence to the printing effect due to moisture absorbing and clustering of a toner. According to the invention, the printing image obtained by using the nonmagnetic negative electricity laser printer ink powder has high image resolution and small backgrounding.

Description

Non magnetic negative electricity ink powder of laser printer
Technical field
The present invention relates to the technical field of ink powder of laser printer, is a kind of non magnetic negative electricity ink powder of laser printer specifically.
Background technology
The ink powder of laser printer can be divided into positive electricity powder and negative electricity powder by being divided into electrical property, can be divided into by magnetic property and have magnetic and non-magnetic, one-component and bi-component can be divided into by component, due to the iron powder containing pitchy in one-component magnetic toner, so can not be used in color printer, think and ensure the versatility of ink powder in printer, the exploitation of one-component non-magnetic toner more and more comes into one's own, the non magnetic negative electricity ink powder of one-component is recycling and almost without useless powder, make photosensitive drums without cleaning balde, drum assembly does not have waste powder hopper, structure simplifies greatly.But in the use of the non magnetic negative electricity ink powder of one-component, the migration of ink powder is entirely by mobility and the charging stability of ink powder self, therefore all much higher than one-component magnetic developer mode to the size-grade distribution of ink powder, spheroidization, charging uniformity and electrification speed, stability.
