Problems solved by technology

The current toner generally has the following problems: the particle size distribution of the toner is wide, resulting in some large toner particles not melting when the toner is used, the printed image is uneven in color and the non-melting toner particles cause clogging and As the printing paper comes out, it becomes inhalable particles suspended in the air, which affects human health and pollutes the air

Abstract

The invention discloses environment-friendly bright black ink powder for printing. The ink powder comprises, by weight, 40-45 parts of polyurethane modified acrylic resin, 22-30 parts of silica sol modified acrylic emulsion, 10-15 parts of modified montmorillonite, 8-11 parts of rosin powder, 2-18 parts of carbon black, 5-8 parts of wax, 5-8 parts of graphene oxide, 1.5-2.5 parts of nano ferriferous oxide, 0-3 parts of charge regulator and 4-12 parts of silane. Materials used in the ink powder are environmentally friendly and simple in formula, the compatibility and black adhesion fastness of an ink powder system are excellent, and the ink powder is durable and does not fade; meanwhile, a product printed by means of the ink powder shows a high-end bright effect under the sunlight, and the texture and grade of the printed product are improved.

Description

technical field [0001] The invention relates to the field of printing toner, in particular to an environmentally friendly bright black toner for printing. Background technique [0002] Toner is one of the most critical factors to ensure printing quality. The main component of toner is not carbon, but most of them are composed of resin and carbon black, charging agent, magnetic powder and so on. At present, there are many kinds of toners on the market, but the general situation is that the production of toners is developing in the direction of refinement, colorization and high speed. The current toner generally has the following problems: the particle size distribution of the toner is wide, resulting in some large toner particles not melting when the toner is used, the printed image is uneven in color and the non-melting toner particles cause clogging and As the printing paper comes out, it becomes inhalable particles suspended in the air, which affects human health and pol...
