Embodiment Construction

[0037] The present invention prepares anti-sublimation heat transfer ink according to the following steps:

[0038] S1: Weigh 20% to 50% of the water-based polymer resin, 20% to 50% of the adsorbent, 5% to 10% of the internal dispersant and the balance of water by weight percentage, and mix the adsorbent, internal dispersant and Add water to the stirring tank and stir and mix at room temperature at a speed of 800rpm to 1200rpm for 60min to 120min to obtain a primary dispersion;

[0039]S2: inject the primary dispersion liquid into a horizontal sand mill, and use zirconium beads with a particle size of 0.3 mm to grind at a speed of 1200 rpm to 1800 rpm for 4 hours to obtain a secondary dispersion liquid;

[0040] S3: Inject the water-based polymer resin and the secondary dispersion liquid into the stirring tank, stir at 800rpm to 1000rpm for 1h to 2h, and then filter through a 0.45μm pore size PP filter membrane to obtain a solid content of 20% to 50% and a viscosity of less th...

Abstract

The invention relates to the technical field of printing ink, in particular to anti-sublimation pyrography ink and a preparation method thereof. The anti-sublimation pyrography ink comprises anti-sublimation resin dispersoid, and the anti-sublimation resin dispersoid comprises water-based polymer resin, an adsorbent, an internal dispersing agent and water. The water-based polymer resin is modifiedacrylic resin or modified polyurethane resin or styrene acrylic resin with the molecular weight ranging from 10,000 to 500,000 and Tg smaller than or equal to 0 DEG C; the adsorbent is nano activatedcarbon or fumed silica or carbon black or activated aluminum oxide; and the anti-sublimation resin dispersoid accounts for 10%-30% of the total weight of the anti-sublimation pyrography ink. According to the pyrography ink, an ideal printing effect can be obtained on a dark-color fabric by directly carrying out heat transfer printing through a conventional pyrography process, the pyrography process can be simplified, the printing efficiency is improved, and the printing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to an anti-sublimation heat transfer ink and a preparation method thereof. Background technique [0002] Heat transfer ink is a special ink used for printing in the field of digital heat transfer. In the printing process, it is necessary to use heat transfer ink to print out the printing pattern on the transfer film, and then transfer the printing pattern on the transfer film to the printing substrate. on the fabric. The printed pattern obtained by the heat transfer process has the advantages of heat resistance, water resistance, friction resistance, light resistance and other performance advantages. [0003] However, since the transfer printing needs to be carried out under high temperature conditions, when the printing fabric is polyester fabric dyed with disperse dyes, it is easy to cause the secondary sublimation of the disperse dyes in the fabric, and then mix into the he...
