Abstract

The invention discloses a temperature sensitive ink, which comprises the following materials in parts by weight: 10 to 30 parts of temperature sensitive pigment, 20 to 60 parts of binder, 25 to 65 parts of solvent, 1 to 2 parts of calcium carbonate, 0.5 to 1 part of defoaming agent, 1 to 3 parts of leveling agent, 2 to 8 parts of 5A molecular sieve, 1 to 2 parts of fumed silica, 2 to 5 parts of dispersing agent and 0.5 to 1.5 parts of adhesion promoting agent. According to the invention, the adhesion of the ink can be enhanced, and the phenomenon of ink infiltration and inking can be prevented, the discoloration speed is quick, the chemical stability is strong, and the storage time is long.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a temperature-changing ink. Background technique [0002] Temperature-changing ink is an ink that appears as one color within a certain temperature range. At present, ordinary temperature-changing inks are mainly divided into organic thermal inks, inorganic thermal inks or liquid crystal thermal inks. The existing ordinary temperature-changing ink can be printed on the glass surface through the silk screen printing process, and it can also be used in other fields such as packaging and decoration. The temperature-changing ink is divided into two forms: reversible and irreversible. The currently used temperature-changing inks mainly have the following defects: 1. Poor wettability: For some materials with low surface energy such as leather, the wettability is poor; 2. Low solid content; 3. High cost; 4. Ink viscosity 5. Poor storage stability and short storage time. Contents of the...
