Abstract

The invention discloses a storable toner and a preparation method thereof and relates to the technical field of print consumables. The storable toner is prepared from the following raw materials: 15 to 35 parts of nano-carbon black, 15 to 30 parts of butyl acrylate, 5 to 15 parts of hollow glass beads, 2 to 6 parts of silicon dioxide, 1 to 5 parts of surfactant, 20 to 30 parts of styrene, 20 to 35parts of azodiisobutyronitrile, 15 to 30 parts of polyvinyl alcohol and 10 to 18 parts of silane coupling agent, wherein the particle size of the hollow glass beads is smaller than 2 microns. The preparation method of the storable toner comprises the following steps: firstly, mixing the butyl acrylate, the styrene and the hollow glass beads; secondly, carrying out polymerization reaction. The toner prepared by the preparation method and a formula provided by the invention has the advantages that storability is excellent and the agglomerating phenomenon is avoided after long-term storage; meanwhile, the comprehensive performance 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 storage-stable toner 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 storage-stable toner, aiming to improve the probl...
