preparation example Construction

[0038] In order to solve the technical problems in the prior art, the invention provides a method and system for preparing toner predispersed material.

[0039] First of all, it should be noted that the kneader mentioned in the present invention is a machine for uniform mixing of semi-dry or viscous materials composed of a pair of intermeshing and rotating Z-shaped or S-shaped blades. the

[0040] The kneader is mainly composed of five parts: the kneading part, the base part, the hydraulic system, the transmission system and the electric control system. The hydraulic system uses a hydraulic station to control the large oil cylinder to complete the opening and closing function, and the hydraulic system uses a hydraulic station to control the oil cylinder to complete functions such as turning over the cylinder and opening the cover. The detailed parameters can be set and requested by the user arbitrarily. Easy to operate and reliable. The transmission system is composed of ele...

Embodiment 1

[0061] The method of the first embodiment specifically includes:

[0062] Step 200, prepare the raw materials and heat the kneader;

[0063] After accurately weighing and marking all kinds of raw materials, put them neatly for use, and check whether the kneader needs to be cleaned; confirm that the kneader is clean, and knead in strict accordance with the process requirements after the heating is completed.

[0064] Step 201, adjusting the rotational speed of the kneader to 200~300 rpm;

[0065] Specifically, it can be 200 rpm, 250 rpm, 300 rpm, etc. The speed of the kneader should not be too fast, so as not to affect the kneading effect due to idling.

[0066] Step 202, adding the first batch of raw materials consisting of the azo pigments, polyethylene wax, and polar wax to a kneader for kneading treatment, and after the first batch of raw materials are kneaded into agglomerates and no dust floats out , continue to add the second batch of raw materials for kneading treatm...

Abstract

The invention provides a preparation method and a system of a toner pre-dispersing material. The method comprises preparing all raw materials and heating a kneading machine; adjusting rotation speed of the kneading machine to be 200-300 circle / minute and using the kneading machine to conduct kneading treatment on the raw materials; adjusting a gap between a first roller and a second roller of a three-roll grinder to be 1-2mm and adjusting a gap between a second roller and a third roller of the three-roll grinder to be 0.5-1mm, enabling the first roller and the second roller of the three-roll grinder to adopt hot rollers and enabling the third roller of the three-roll grinder to adopt a cold roller; adjusting rotation speed of the three-roll grinder to be 300-400 circle / minute; and adding materials treated by the kneading machine between the first roller and the second roller of the three-roll grinder, and treating and grinding the materials through the three rollers to obtain the toner pre-dispersing material. The preparation method and the system adopt the kneading machine for fusion and the three-roll grinder for repeated grinding and enable organic pigments to be sufficiently soaked and wrapped by a dispersing agent to remove harmful effects that organic pigment particles are difficult to disperse due to aggregation and the like.

Description

technical field [0001] The invention relates to a method for preparing a pigment, in particular to a method and system for preparing a toner predispersed material. Background technique [0002] Organic pigments refer to a class of pigments made from organic compounds that have color and a series of other pigment properties. Pigment properties include light fastness, acid resistance, alkali resistance, organic solvent resistance, heat resistance, crystal stability, dispersion and hiding power, etc. The difference between organic pigments and dyes is that they have no affinity with the object to be colored, and only disperse the organic pigment evenly in the object to be colored through physical action to make the object colored. The intermediates, production equipment and synthesis process required for its production are similar to the production of dyes, so the production of organic pigments is often organized in the dye industry. Compared with ordinary inorganic pigments,...
