Abstract

The invention discloses thermal transfer printing ink and a preparation method thereof. The thermal transfer printing ink is prepared from the following components in parts by weight: 15 to 25 parts of heat transfer printing disperse dye, 1 to 4 parts of rosin polyether sulfonate, 0.1 to 0.5 part of graphene, 10 to 15 parts of betaine, 1 to 3 parts of rose extract, 15 to 20 parts of hyperbranched polyglycerol, 1 to 2 parts of water-soluble chitosan, 0.1 to 0.5 part of preservative, 0.3 to 0.6 part of macromolecular surfactant, 30 to 40 parts of water and 10 to 20 parts of alcohol solvent. The invention also discloses a preparation method of the thermal transfer printing ink. The thermal transfer printing ink is high in fixation rate, antibacterial, good in storage stability, high in printing fluency, excellent in color reducibility, remarkable in waterproof, scratch-resistant and sun-proof effects, safe and environment-friendly to use and not liable to age, and white smoke and odor cannot be generated during color development of the ink.

Description

technical field [0001] The invention relates to the technical fields of fine chemical industry and light chemical industry, in particular to a thermal transfer printing ink and a preparation method thereof. Background technique [0002] Thermal transfer ink is also called sublimation ink, which is mainly used for heating transfer printing products. Thermal transfer ink can clearly print patterns and characters on other products after being heated by a thermal transfer machine, so it is a thermal transfer ink. One of the essential materials in the transfer printing industry. Compared with other dye inks, pigment inks and water-based inks, thermal transfer inks are bright and thick in color and high in density. After being heated and transferred by a thermal transfer machine, The image is clear and the color reproduction is high. Its appearance has aroused people's extensive attention, and the development of thermal transfer ink with excellent comprehensive performance has be...
