Embodiment 1

[0040] The preparation of black toner among the present invention comprises the steps:

[0041] (1) According to the formula proportioning in table 1, styrene-acrylic resin, dispersion black, wax, charge regulator are mixed uniformly, form mixture A;

[0042] (2) The mixture A is melted and mixed by a kneader (mixing temperature 100° C.), and then pressed into tablets to form flakes, which are then mechanically crushed to a particle size of 1 to 2 mm;

[0043] (3) The flakes that have been mechanically crushed enter the jet mill (pressure 1.0MPa, frequency 50Hz), ultra-fine crushing and grading system (speed 15000rpm, air volume 100Nm 3 / h), to obtain a graded product with a volume D50 of 6-7 μm;

[0044] (4) After mixing the classified product and the external additive, stirring for 5 minutes at a stirring rate of 30 m / s, a black toner was obtained.

Abstract

The invention discloses colorful powdered ink, a preparation method thereof and a method for digital thermal transfer printing. The colorful powdered ink is composed of, by mass, 77-95% of resin, 2-8% of disperse dye, 2-7% of paraffin, 0.1-4% of charge control agent and 0.9-4% of external addition agent. The colorful powdered ink, with disperse printing dye, prepared through a dry-type physical method has the function of thermal transfer printing. After patterns are printed through a laser printing machine, the patterns can be subjected to transfer printing on substrates of textile products, ceramic, metal, glass, plastic and others through transfer printing equipment by the adoption of a thermal transfer technology of 180-230 DEG C and 10-120 s. Compared with a current ink-spraying thermal transfer technology, the method for digital thermal transfer printing has the advantages that printing speed is high, the production technology is mature, the production process is safer and environmentally friendlier, cost is low, the substrates are wide in application range, the firmness of the patterns after transfer printing is good, and the method is suitable for large-scale printing and personalized customization.

Description

technical field [0001] The invention relates to a color toner used in laser printers and copiers, in particular to a color toner, a preparation method thereof, and a digital thermal transfer printing method. Background technique [0002] Laser printers and electrostatic copiers are the main equipment of office automation. Toner, the main consumable for printing and copying, has a huge market and has become the main growth point of industry output value and profit. [0003] Color toner (also known as color toner) is a key consumable for color laser printing and color digital copying. It is mainly composed of resins, pigments, charge regulators, and various additives. At present, toner preparation methods are mainly divided into two types: physical method (that is, traditional melting and pulverization method) and chemical method (suspension polymerization method, aggregation-fusion method, etc.). [0004] At present, laser printing color toners used in office usually use org...
