Abstract

The invention discloses high-temperature-resistant printing ink and a preparation method thereof. The preparation method comprises the steps that firstly, ethyl silicate, azodicarbonamide and nano titanium dioxide are mixed to prepare a mixture M1; secondly, organic amine is added into the mixture M1 dropwise to react to prepare a mixture M2; thirdly, the mixture M2, diaminodiphenyl sulfone, 2-methyl imidazole and dibutyl phthalate are mixed to prepare a curing agent; fourthly, the organic silicon resin, the curing agent, kaolin, barium sulfate and a silane coupling agent are mixed to preparethe high-temperature-resistant printing ink. According to the preparation method, ethyl silicate, azodicarbonamide and nano titanium dioxide are mixed, then organic amine is added into the mixture dropwise, the mixture is mixed with diaminodiphenyl sulfone, 2-methyl imidazole and dibutyl phthalate, and then the curing agent is mixed with organic silicon resin, kaolin, barium sulfate and the silanecoupling agent, so that the printing ink prepared from the materials has good effects of preventing fading, yellowing and the like at a high temperature.

Description

technical field [0001] The invention relates to the field of production and preparation of inks, in particular to high-temperature resistant inks and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the living environment, and the development of ink has also greatly improved the decorative effect in daily life. However, in daily use, it is often found that when the ink encounters a high temperature environment, it is very easy to cause problems such as yellowing and fading in a short period of time, resulting in a decrease in its performance. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a high-temperature-resistant ink that can effectively reduce problems such as fading and the like under long-term use in a high-temperature environment and a preparation method thereof. Contents of the invention [0004] In view of t...
