Abstract

The invention discloses powdered ink for a laser printer and a preparation method thereof, and relates to the technical field of printing consumables. The powdered ink for the laser printer is prepared from the following raw materials of 13 to 30 parts of carbon black, 15 to 35 parts of butyl acrylate, 5 to 15 parts of hollow glass beads, 3 to 6 parts of silicon dioxide, 1 to 5 parts of surfactant, 15 to 30 parts of styrene, 18 to 35 parts of azodiisobutyronitrile, 18 to 30 parts of polyvinyl alcohol, and 8 to 15 parts of polypropylene wax, wherein the particle size of the hollow glass bead issmaller than 2 micrometers. The preparation method of the powdered ink for the laser printer comprises the following steps of firstly, mixing the butyl acrylate, the styrene and the hollow glass beads, and then performing condensation reaction. The powdered ink adopting the formula and the preparation method has the advantages that the storable property is excellent, the caking is avoided even ifstoring for a long time, the comprehensive property is excellent, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of printing consumables, and in particular to a toner for a laser printer and a preparation method thereof. Background technique [0002] Toner is the main consumable used in photographic processes such as electrostatic copying and laser printing. With the development of information technology and office automation, equipment such as electrostatic copiers, laser printers and fax machines have become the main tools for information dissemination. Therefore, for toner demand is also increasing. [0003] The extensive use and replacement of laser printers has put forward higher requirements for toner. However, the existing toner has the problem that it cannot be stored for a long time, and slight agglomeration occurs during the storage process, resulting in poor printing effect. Contents of the invention [0004] The object of the present invention is to provide a toner used in laser printers, aiming to impr...
