According to different needs, toner production is developing in the direction of refinement, colorization, and high speed. There are many traditional methods for manufacturing toner, mainly pulverization and polymerization. The polymerization process is complicated, the waste of water resources is serious, and the industrial wastewater produced There are also many, which have a great impact on the environment, and the technical difficulty is high, and the professionalism required is also very high. At present, the pulverization method is more widely used.
However, there are also many defects in the pulverization method. The distribution of the components in the toner is not uniform enough, and the printing and imaging of the toner has poor adhesion stability and poor fluidity. Phenomenon that affects the quality of toner

The invention relates to a preparation process flow of colored carbon powder. The process flow comprises the following steps: proportionally adding resin, a colorant, a charge control agent and magnetic powder into a high-speed mixer, performing mixing, sequentially processing the mixture into sheets by an internal mixer and a cooling tablet press, carrying out coarse crushing and secondary crushing, and adding a release agent in the crushing process to obtain a semi-finished product; adding a dispersing agent into the semi-finished product, performing mixing on a high-speed mixer and performing sieving to obtain a finished product. The preparation process of the colored carbon powder provided by the invention is simple in flow, suitable for industrial production, uniform in carbon powdersize and more sufficient in mixing, the produced carbon powder is better in stability, the transfer printing efficiency of the carbon powder is greatly improved, the waste powder rate of the carbon powder is reduced, and the phenomenon of a use interruption point is also greatly reduced.
Description
technical field [0001] The invention relates to the field of manufacturing carbon powder, in particular to a process flow for preparing colored carbon powder. Background technique [0002] Toner, also called toner, is a powdery substance used in laser printers for imaging and fixing on paper. Toner is divided into black toner and colored toner, with rich colors. Black carbon powder is composed of binder resin, carbon black, charge control agent, external additives and other components. Pigments of other colors, etc. also need to be added in the color toner. According to different needs, toner production is developing in the direction of refinement, colorization, and high speed. There are many traditional methods for manufacturing toner, mainly pulverization and polymerization. The polymerization process is complicated, the waste of water resources is serious, and the industrial wastewater produced There are also many, which have a great impact on the environment, and the ...
