preparation example Construction

[0020] The preparation method of the thermal sublimation ink suitable for lithographic printing described in the present invention, the specific steps of the method are as follows: first melt the lipophilic surfactant at 70-80°C, slowly add the dye, stir while adding, wait for the dye to After adding everything, stir at high speed; after it is dispersed evenly, add alkyd resin and stir until evenly dispersed, put the material into a three-roller mill for more than 70 minutes, until the fineness of the material is less than 7.5 microns, and the dye base is formed Ink; mix dye-based ink and lithographic ink binder, turn on mechanical stirring, and stir at high speed for 30 minutes to fully wet the two to form a slurry, add viscosity modifier and anti-drying agent, adjust the viscosity to 40000‐70000mPa.s / 25 ℃, filling ink finished product.

Abstract

The invention discloses thermal sublimation ink applicable to planographic printing and a preparation method thereof. The thermal sublimation ink comprises the following constituting components in parts by weight: 30-80 parts of base dye ink, 20-40 parts of planographic printing ink connecting material, 1-15 parts of viscosity regulating agent and 0.5-1 part of antidesiccant, wherein the base dye ink comprises the following components in parts by weight: 15-45 parts of dye, 25-45 parts of lipophilic surfactant and 5-10 parts of alkyd resin; the dye is dispersed dye with the thermal sublimation dying function. The thermal sublimation ink has the beneficial effects that the ink adopts a special base dye ink production process, not only can the dye be dispersed in an oil system, but also the dispersion concentration of the dye can be 35%, which is far higher than the level of about 25% of the ordinary ink. The ink can be used for transfer printing for multiple times, and the concentration in each transfer printing can be greater than 1.0.

Description

technical field [0001] The invention relates to the field of ink, and mainly relates to a sublimation ink suitable for lithographic printing and a preparation method thereof. Background technique [0002] Sublimation is the process in which a substance changes directly from a solid state to a gaseous state without going through a liquid state. Sublimation transfer printing, also known as "gas dyeing", is to use dye-based inks with sublimation conditions to print images and texts on paper in a mirror-reversed manner through printing, and then place the printed paper on the substrate In the above process, the pigment in the ink on the paper is sublimated and transformed into a gaseous state by means of heat and pressure, thereby transferring the image and text to the substrate. Nowadays, many printed cloths (clothes), shoes and blankets use sublimation transfer printing. [0003] Since most sublimation dyes contain non-ionic polar groups, have a small molecular weight and ha...
