摘要: Toner particles are prepared by a process comprising providing an extrusion apparatus; adding resin particles and additive particles to a supply means in the extrusion apparatus; adding the resin particles and the additive particles to a blending chamber in the extrusion apparatus, which blending chamber is maintained at a temperature of from about 50° C. to about 120° C.; blending the resin particles and the additive particles to form a mixture; extruding the resin particles to form extruded material; injecting liquid substances, which have a lower boiling point than the melt temperature of the resin particles, into the blending chamber during extrusion without the application of a vacuum to remove the liquid substances prior to extrusion; and grinding the extruded material to form toner particles.

摘要: Processes for preparing toner compositions used with electrostatographic imaging members. The processes utilize screw extruders to facilitate continuous dispersion and aggregation of toner components, such as color pigments and wax. The continuous dispersion produces the toner components with more control and better product yield. The products produced are also improved in quality.

摘要: The continuous process for manufacturing toners disclosed herein includes continuously feeding components of a toner composition into a feed section of a screw extruder at a controlled rate. The continuous process for manufacturing toners may include feeding the components of a toner composition into the feed section of a screw extruder without performing an external or secondary dispersion step. That is to say, the components of the toner composition may be fed directly into the extruder without using dispersions of individual components as used in batch processes. Rather, the toner components are added to the extruder in dry form, melt-mixed, and may be dispersed in aqueous form in the extruder. The process may produce micron-sized toner particles, thus no further size reduction may be necessary.
摘要翻译: 本文公开的用于制造调色剂的连续方法包括以受控的速率将调色剂组合物的组分连续进料到螺杆挤出机的进料段中。 用于制造调色剂的连续方法可以包括将调色剂组合物的组分进料到螺杆挤出机的进料部分中,而不进行外部或二次分散步骤。 也就是说,调色剂组合物的组分可以直接进料到挤出机中而不使用分批方法中使用的各个组分的分散体。 相反,调色剂组分以干燥形式加入到挤出机中,熔融混合,并且可以以水性形式分散在挤出机中。 该方法可以产生微米级的调色剂颗粒,因此不需要进一步的尺寸减小。

摘要: A process for preparing toner compositions using a dry pigment is provided. The process comprises combining a base toner resin composition, a dry pigment, and dispersion agent in a one step process, without the need any pre-processing of the pigments such as by, for example, flushing. The process includes combining the base toner resin, dry pigment and dispersion agent in a processing apparatus such as an extruder. The process may also comprise preparing the toners via an extrusion process utilizing a screw having a configuration designated herein as a Type C screw.
