The content of the invention
In order to overcome the shortcoming of prior art, the present invention to provide a kind of ultralow magnetic single component suitable for magnetic developer roller
Ink powder and preparation method.Its process is simple, low cost, powder consumption is low.
A kind of ultralow magnetic single component powdered ink suitable for magnetic developer roller includes following weight portion：65-90 parts of resin, 2-
18 parts of magnetics, 0-10 parts of colouring agent, 0.5-8 parts of wax, 0.1-4 parts of charger and 0.5-8 parts of additives.
Described colouring agent is carbon black.
Described charger is metal salicylate complex compound, metallic azo complex, aniline black byestuffs, doped quaternary ammonium salt or triphen
Methane complex compound.
Described additive is hydrophobic silica, titanium dioxide, alundum (Al2O3) or PMMA (poly-methyl methacrylates
Ester).
A kind of preparation method of ultralow magnetic single component powdered ink suitable for magnetic developer roller, comprises the following steps：1), will
Resin, magnetic, colouring agent, wax and charger are weighed in the ratio, and charging feedstock mixer is sufficiently mixed 10-30 minutes；2)、
Kneading machine mixing is pressed into sheet；3) particle of the coarse crushing into particle diameter less than 3mm；4), divided by after airflow milling crushing and classification
Level product, classification product particle size D50V is 6-14 μm；5), to the additive that the weight portion is added in classification product, mixer fills
Divide mixing 3-30 minutes, cross 50-200 mesh sieves.
The present invention has following advantages：1), powder consumption is low, is calculated by 5% coverage rate, and every page of consumption powder is less than 2.6mg, than
