Description

Environment-friendly color ink powder for printing

Technical Field

The invention relates to the field of printing ink powder, in particular to environment-friendly color ink powder for printing.

Background

Toner is one of the very critical factors that ensures print quality. The main component of the toner is not carbon, but most of them is composed of resin and carbon black, a charge agent, magnetic powder, and the like. At present, the ink powder on the market is diversified, but the great trend is that the carbon powder production develops towards refinement, colorization and high speed. The current toners are generally subject to the following problems: the particle size distribution range of the toner is wide, so that a part of large toner particles of the toner are not melted when the toner is used, the printed image is blocked due to uneven color and the unfused toner particles are suspended in the air along with the printing paper and become inhalable particles, and the traditional color pigment also has certain toxicity, influences the human health and pollutes the air.

Therefore, it is necessary to design an environmentally friendly toner for color printing to develop new prospects following the development of situation.

Disclosure of Invention

The invention aims to provide an environment-friendly color ink powder for printing, which adopts more environment-friendly raw materials, ensures the adhesiveness and fastness of various colors of pigments, and even naturally emits unique luster so as to overcome the problems in the prior art.

In order to achieve the above purpose, the technical scheme of the invention is as follows:

an environment-friendly color ink powder for printing comprises the following components in parts by weight:

preferably, the modified acrylic resin is a silica-modified acrylic resin. The silicon dioxide modified acrylic resin has good compatibility and stability to other substances in the system.

Preferably, the particle size range of the nano ferroferric oxide is 8-40 nm. The ferroferric oxide has good magnetism, fluidity and dispersibility due to the grain size.

Preferably, the color pigment powder includes white pigment powder, red pigment powder, yellow-green pigment powder, blue pigment powder and black pigment powder. The combination of black and white pigment powder and tricolor pigment powder can form most colors.

Further, the white pigment powder is one of fumed silica, titanium dioxide, zinc oxide and pearl powder, the red pigment powder is one of iron oxide red, cerium sulfide, hematite, pyrite sinter, Venice red and cuprous oxide, the yellowish green pigment powder is one of nickel oxide, cobalt green, iron oxide yellow, cobalt yellow and mosaic gold, the blue pigment powder is one of Prussian blue, Tengshan blue, cobalt violet and ultramarine, and the black pigment powder is one of carbon black, manganese oxide and lamp black. The pigment powder is inorganic mineral or simple artificial composition, and is stable in performance and environment-friendly compared with the unstable organic pigment and the pigment containing a large amount of heavy metals.

Preferably, the silane comprises dimethyldichlorosilane and hexamethyldisilazane, and the ratio of the dimethyldichlorosilane to the hexamethyldisilazane is (2-3): 1. the silane species and the composition thereof enable the surface, compatibility and bonding of the system to have strong comprehensive improvement performance.

Preferably, the charge regulator is one of a tert-butyl salicylic acid metal complex, an azo metal complex and a benzilic acid metal complex. The charge regulator has stable regulation and lasting efficacy.

The invention has the beneficial effects that: the color toner is environment-friendly and has good color blending. The nano ferroferric oxide has magnetism and excellent fluidity; the polyethylene wax, the rosin powder and the organic modified diatomite ensure that the toner system has good performances of compatibility, bonding and the like; the framework of the ink powder formed by the modified acrylic resin and the styrene-acrylic resin and the base material have good comprehensive performance; the color pigment powder is obtained from natural inorganic minerals or is primarily processed manually, and has stable pigment performance and environmental friendliness. The toner disclosed by the invention is simple in formula, comprehensive in performance, good in component compatibility, dispersibility and durability in use, comprehensive in color blending, stable in coloring and environment-friendly, and is prepared from inorganic minerals or primary processing products thereof.
