Problems solved by technology

However, due to the low polarity of the dye, it is not only insoluble in water, but also has a weak binding force with many dispersants, so it is prone to secondary aggregation and poor storage stability.

Abstract

The invention discloses water-based nanometer color paste, water-based thermal sublimation jet ink containing the same, and a method for preparing the water-based thermal sublimation jet ink. The water-based nanometer color paste is prepared from, by weight, 10-40 parts of thermal sublimation dye, 1-20 parts of cladding treating agent, 1-80 parts of dispersing agent, 1-30 parts of auxiliaries and 1-400 parts of water. The thermal sublimation dye in the water-based nanometer color paste exists in the form of dye particles, and the mean grain size of the dye particles is smaller than 100 nanometers. A unique two-step dispersion technology is adopted, the thermal sublimation dye is subjected to surface cladding and nano-scale dispersion in sequence, and then the stable water-based nanometer color paste is obtained. The obtained water-based nanometer color paste is evenly mixed with resin, auxiliaries, cosolvent and water to obtain the water-based thermal sublimation jet ink.

Description

technical field [0001] The invention relates to the fields of chemical industry, materials and environmental protection, in particular to a water-based nano color paste, a water-based sublimation ink-jet ink containing the same and a preparation method thereof. Background technique [0002] Sublimation ink is a kind of disperse dye ink. Different from conventional inks, sublimation inks need to undergo high temperature to transfer the color to the object to show the original color, that is to say, before heat treatment, the color displayed by sublimation ink on the transfer paper is not the final color. color. The color development principle of sublimation ink is that, using the sublimation phenomenon, the dye in the ink is directly converted from solid to gas at high temperature, so that the color is transferred from the transfer paper to the surface of the object to be transferred. [0003] Stability is one of the most important properties of sublimation ink in practical...
