Problems solved by technology

At present, despite the rapid development of inkjet printing technology without water and less water, it is still difficult to achieve large-scale promotion and application due to the disadvantages of the technology itself, such as slow printing speed, expensive ink, and easy clogging of nozzles, resulting in the use of screen printing Traditional printing methods represented by long production cycles, high energy consumption, and large sewage discharges still occupy a relatively high proportion in textile printing production.

Embodiment 1

[0045] The preparation of black toner among the present invention comprises the steps:

[0046] (1) According to the formula ratio in Table 1, polyester resin, styrene-acrylic resin, disperse black, carbon black, wax, charge regulator, fiber swelling agent are mixed uniformly to form mixture A;

[0047] (2) After the mixture A is melted and mixed in a kneader (mixing temperature 100° C.), it is cooled and pressed into tablets to form flakes, and the flakes are then mechanically crushed to a particle size of 1 to 2 mm;

[0048] (3) The flakes that have been mechanically crushed enter the jet mill (pressure 0.9MPa, frequency 45Hz), ultra-fine crushing and grading system (speed 14000rpm, air volume 80Nm 3 / h), to obtain a graded product with a volume D50 of 7-8 μm;

[0049] (4) After mixing the graded product and the external additive, stirring for 10 min at a stirring rate of 30 m / s, a black toner was obtained.
