Preparation method of easy-to-remove glass printing ink

Abstract

The invention provides a preparation method of easy-to-remove glass printing ink. The preparation method comprises the following steps: preparing a pigment; preparing an ink binder; preparing the materials, wherein high-temperature printing ink and tempered printing ink are subjected to ink blending according to a mass ratio of 1:7; stirring, wherein the pigment, the ink binder, the ink and an auxiliary agent are weighed according to the amount, and put into a blending barrel, stirring is performed by using a stirrer at a low speed to prevent toner from flying, and then stirring is performed at a high speed until the ink material is blended into paste; carrying out rolling grinding, wherein the pasty ink material is rolled and grinded through a grinding machine so as to disperse the pigment in the ink binder; and mixing, after ink rolling, part of the solvent, varnish, the auxiliary agent and the rolled ink material are uniformly mixed until the required viscosity is reached so as to obtain the ink. The ink prepared by the invention realizes good printing and heat transfer printing on glass, can be removed from the glass after high temperature of 600 DEG C, can be recycled, and iseconomic and environment-friendly.

Description

technical field [0001] The invention belongs to the field of printing and dyeing materials, and more specifically relates to a preparation method of an easy-to-clear glass printing ink. Background technique [0002] The inks used in the printing industry are generally used for paper printing or inkjet printing of documents by printers, or for directly writing on glass. However, this kind of ink has low temperature resistance and contains harmful ingredients that will cause environmental pollution. Chinese patents 02124255.0 / 97111774.8 and 96101181.5 propose a clean printing technology, which directly prints patterns or words on the printing area on the glass, and the words and patterns on the glass are transferred to the substrate by hot pressing; the glass has The residual graphics can be removed, and the clean glass is recycled to the printing area for reuse. After the realization of this clean printing and dyeing technology, it can solve the problem of a large amount of ...
