Abstract

A diacetylene temperature-sensitive color-changing ink and a preparation method thereof. The diacetylene temperature-sensitive color-changing ink is composed of the following raw materials in parts by mass: diacetylene temperature-sensitive color-changing material: 8-15 parts; vegetable oil-type varnish : 40-50 parts; calcium carbonate: 20-25 parts; barium sulfate: 10-15 parts. The diacetylene temperature-sensitive color-changing ink of the present invention has evenly dispersed color components, strong viscosity with printed matter, and no fading phenomenon. The equipment used in the preparation process is simple, easy to transform into mass production, easy to promote, and forms production capacity. The raw and auxiliary materials used Food-grade materials are selected in accordance with the regulations, which can be used for food packaging and printing.

Description

technical field [0001] The invention belongs to the field of screen printing inks for paper, and in particular relates to a diacetylene temperature-sensitive color-changing ink and a preparation method thereof. Background technique [0002] Thermochromic inks have been widely used in daily life, but most of them contain toxic or harmful substances, which are restricted when used in the field of food or food packaging materials. Usually, reusable packaging containers for food or medicine need to be sterilized at high temperature. During disinfection, real-time monitoring of the disinfection effect is required. Since the containers are stacked together during disinfection, they will affect each other, and some containers cannot reach the temperature set for disinfection, but the disinfection effect cannot be judged intuitively. In addition, if the traditional temperature-sensitive color-changing ink is used, it is easy to cause secondary pollution, and the purpose of disinfec...
