Abstract

The invention discloses high-temperature and low-temperature resistant printing ink and a preparation method thereof. The problem that labels crack under the high / low-temperature using environment is solved. According to the technical scheme, the high-temperature and low-temperature resistant printing ink is prepared from, by weight, 20-30 parts of organic silicon resin, 10-20 parts of acrylic resin, 10-15 parts of a grease solvent, 10-15 parts of carboxy methyl amylum ester, 10-30 parts of temperature-resistant padding, 1-3 parts of a straight-acrylic dispersant, 1-3 parts of anti-cracking additive and 0.5-2 parts of a flatting agent. The prepared printing ink can bear the high temperature and the low temperature on the high-temperature using occasion and the low-temperature using occasion, and the application universality of the printing ink is enhanced.

Description

technical field [0001] The invention relates to printing ink, in particular to a high and low temperature resistant ink and a preparation method thereof. Background technique [0002] Ink is a substance used to form graphic information in the printing process. It is a paste-like adhesive body with a certain fluidity composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, and additional materials. A homogeneous mixture that can be printed and dried on the printed body. Therefore, the ink should have bright colors, good printing adaptability, and appropriate drying speed. In addition, it also has certain application indicators such as resistance to solvents, acids, alkalis, water, light, heat, abrasion resistance, sterilization and mildew resistance. [0003] The back of the existing label is often pre-cured with ink, and the label can be bonded to the product carrier by using the cohesive force of the ink. However, in some...
