Abstract

The invention discloses thermosensitive color-changing microcapsule UV (Ultraviolet) photo-cured printing ink and a preparation method thereof, and belongs to the technical field of printing ink. The thermosensitive color-changing microcapsule UV photo-cured printing ink is prepared from the following raw materials in parts by weight: 22 to 60 parts of epoxy acrylate, 15 to 25 parts of color developing microcapsule, 15 to 25 parts of polyester acrylate, 10 to 15 parts of dipropylene glycol diacrylate, 5 to 10 parts of trimethylolpropane triacrylate, 5 to 10 parts of acrylic acid-4-polyhydroxybutyrate, 0.5 to 3 parts of benzil dimethyl ketal, 1 to 5 parts of dispersing agent, 1 to 5 parts of hollow glass beads and 1 to 3 parts of UV varnish. The thermosensitive color-changing microcapsule UV photo-cured printing ink is cured by UV, and has the advantages of high drying speed, good fixing effect, clear meshes, water resistance, solvent resistance, abrasion resistance and the like, is almost zero in VOCs (Volatile Organic Compounds) emission, is environment-friendly, and has a wide application range and a higher application value.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a heat-sensitive color-changing microcapsule UV photocurable ink and a preparation method thereof. Background technique [0002] Heat-sensitive paint is a chemical decomposition reaction under a certain temperature and pressure, and becomes a new substance, thus reflecting different colors. In the prior art, heat-sensitive paints are prone to rapid fading when stored at humid room temperature or slightly higher temperature, and the process of making heat-sensitive paints is cumbersome, and the general formula uses solvents, which causes great environmental pollution. It is of little significance to make it into a solvent-based ink, but to make it into a paste ink has poor dispersion and poor color rendering effect. This is a technical problem that cannot be solved for a long time in the industry. [0003] UV ink is a kind of printing ink. It is an ink that is cured and dried by ult...
