[0032] The second aspect of the present invention provides a kind of preparation method of described novel hot press printing ink, and the step comprises at least:

[0033] S1: Stir and mix the wetting agent, acid-base regulator, surfactant, bactericide, and deionized water evenly to obtain the first mixed solution:

[0034] S1: Add resin and curing agent to the first mixed solution in turn, stir and mix evenly, and ensure to stir for more than half an hour to obtain the second mixed solution:

[0035] S3: Add the pigment dispersion liquid to the second mixed liquid, stir and mix evenly, and age for four hours to obtain the third mixed liquid:

[0036] S4: Filter the third mixed solution twice with a PP membrane with a pore size not greater than 0.45 μm, and take the filtrate.

Abstract

The invention discloses pyrography water-based white ink suitable for an Epson nozzle, and a preparation method thereof, and belongs to the technical field of printing ink. The pyrography water-based white ink suitable for the Epson nozzle is prepared from, by mass,20 to 40 percent of a pigment dispersion liquid, 20 to 40 percent of resin, 0.2 to 3 percent of a curing agent, 0.1 to 0.5 percent of an acid-base regulator, 10 to 30 percent of a wetting agent, 0.2 to 2.0 percent of a surfactant, 0.1 to 0.2 percent of a bactericide, and the balance of water. The printing fluency on all Epson sprayers is good, the standby performance is good, the fastness is high, moisture regaining is not prone to occurring, covering is good, ink flowing of any film is avoided, and mutual halo of color ink is avoided.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to the water-based white ink for heat press suitable for Epson nozzles. Background technique [0002] Customized heat press technology is a popular trend in recent years, and it is very popular in the clothing circle. Because it can be applied to a variety of fabrics, whether it is high-elasticity jerseys or low-elasticity advertising shirts, shipping marks, shoe labels, etc., it is very suitable to use heat transfer to print patterns, the patterns are bright and the price is affordable. [0003] Traditional heat press is to print the transfer film with weak solvent, then engrave and transfer. The disadvantage is that the weak solvent has a strong smell, needs engraving, cannot print gradients, cannot print small characters, and has serious white edges. The new type of hot stamping ink is to print PET film first, then sprinkle hot-melt powder on the pattern, bake to melt the...
