Novel pyrograph color ink suitable for Epson repiece

Abstract

The invention relates to a novel pyrograph color ink suitable for Epspinning, which comprises 20-40% of a pigment dispersion liquid, 20-30% of resin, 10-30% of a wetting agent, 0.2-2.0% of a surfactant, 0.1-0.2% of a bactericide, 0.1-3% of a film forming agent polyvinylpyrrolidone, and the balance of water. A preparation method includes steps of: sequentially adding a wetting agent, a surfactant, a bactericide, deionized water and a coalescing agent, uniformly stirring and mixing the components to obtain a primary mixed solution, the stirring time lasting for more than 2 hours; sequentially adding resin into the preliminary mixed solution, and uniformly stirring and mixing the components to obtain a mixed solution; adding the pigment dispersion liquid into the mixed liquid, uniformly stirring and mixing the components, and aging the mixed solution for 2 hours; filtering the aged mixed solution twice by using a glass fiber membrane with the pore diameter precision of not more than 1.0 micron and collecting the filtrate. the novel pyrograph color ink suitable for the Epson repiece does not dry or plug in a standby test of a printer, is good in continuous printing performance, and solves the technical problems that PET films with various qualities cannot be compatible, various pyrograph white inks are poor in compatibility, oil returns, ink flows and the like.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a novel heat transfer color ink suitable for Epson heads. Background technique [0002] With the development and progress of society, the demand for printing advertisements, photo printing, etc. is also increasing, and printing technology is also advancing with society to meet the needs of the market. [0003] The heat transfer process is very popular because it can be customized, bright in color, high in fastness, and suitable for a variety of materials. But at present, the price of PET film is different, and the quality is uneven. [0004] Color inks generally need to be printed on the bottom and then covered with white ink. However, the performance of color inks in the market is not good enough, and the film is seriously problematic. When encountering cheap films, it is easy to smudge, return oil, or even flow ink, and the compatibility of white ink is poor. Cheap films and...
