Abstract

The present invention provides a method for manufacturing yellow carbon powder for color laser printing by using multi-component mixed resin. By adding polyester resin and epoxy resin into copolymerized styrene-acrylic acid resin, triboelectrification performance of powder can be improved, and the powder achieves relatively low melt temperature and relatively high glass transition temperature, and heating performance is improved, and a melt property is improved at a relatively low temperature; and By adding the three types of resin, fixing performance and developing performance of the powder can be improved, a fixing temperature range becomes wider, a fixing effect becomes better, color mixture becomes uniformer, a developing fastness degree is increased, the demands of multiple types of printers are met, and an application range of the powder is expanded.

Description

technical field [0001] The invention relates to the preparation technology of yellow toner for color laser printing, in particular to a method for preparing yellow toner for color laser printing with multiple mixed resins. Background technique [0002] At present, with the increasing use of color printing, customers have higher and higher requirements for printing or copying quality, and the fixing and developing toner originally used in black printers are less and less able to meet the demand. The specific performance is: (1) The fixing temperature must meet the requirements of the fixing range of the color copier; (2) The fixing stability is not good enough: (3) The color reproduction degree is not enough; (4) The fixing degree is low and ghosting is easy to occur; ( 5) In addition, due to the development of more and more printers of various types, it is difficult to have a kind of toner that can meet the needs of multiple printers. Contents of the invention [0003] In...
