Pyrography ink with high ink bearing capacity and preparation method thereof

Abstract

The invention provides pyrography ink with high ink bearing capacity and a preparation method of the pyrography ink. The pyrography ink comprises a pigment dispersion, a water-soluble organic solvent, water-soluble film-forming resin, a coalescing agent, a dispersing agent and a surfactant, the water-soluble film-forming resin is modified polyurethane resin with the glass transition temperature lower than-5 DEG C, the film-forming auxiliary agent comprises at least one of alkynediol, polyether modified organic silicon and alkyl diol, and the ratio of the film-forming resin to the film-forming auxiliary agent is 300: 1-150: 1. By controlling the addition amount of the coalescing agent, during film forming, the coalescing agent reduces the glass transition temperature of film-forming resin and accelerates the film forming speed of ink on a pyrograph medium, so that the ink can be rapidly fixed on the pyrograph medium and forms a film, the plasticization effect of the coalescing agent on the film-forming resin is realized, the conditions of halo ink, flowing ink, diffusion and the like are avoided, and the film-forming efficiency is improved. The problems that ink is low in ink bearing capacity and poor in compatibility with a transfer printing film are solved.

Description

Technical field [0001] The present invention relates to the field of ink, in particular to a high ink-bearing hot stamping ink and a method for preparing it. Background [0002] Hot stamping ink is a special ink used for printing in the field of digital hot stamping, when using it is necessary to first print the hot stamping ink to a special bearing medium to form a printing pattern, and then transfer the printing pattern on the bearing medium to the printing fabric after high temperature. The ink on the bearing medium is pressed and finished under high temperature conditions, and transferred to the printing fabric, which has the advantages of high temperature resistance without yellowing, washability, rubbing resistance, and good sun resistance, and is suitable for printing personalized T-shirts, advertising shirts, personal characteristic clothing, etc., which are welcomed by everyone. As mentioned above, the ink needs to be printed on the corresponding transfer film when using...

Problems solved by technology

As mentioned above, the ink needs to be printed on the corresponding transfer film when used. For this type of ink, the amount of ink on the transfer film will affect the vividness of the color of the ink transferred on the clothes and the pull of the pattern. Stretchability, which affects the use of users

[0003] However, the performance of color inks in the current market is not good enough, and the film is seriously selected. In addition, the quality of the transfer film with different prices is uneven, and the ink capacity is small, which will lead to ink blurring and ink flow when printing with a large amount of ink on cheap film. , diffusion or infiltration, etc., which makes the printed image look dirty, blurred, with reduced contrast, and the imaging is not delicate and uniform enough, which seriously affects the customer experience
