Temperature change printing ink production technology

Abstract

The invention discloses a temperature change printing ink production technology. The printing ink comprises the following components in percentage by weight: 36-39% of water-based acrylic resin, 18-22% of temperature change pigment, 0-10% of common pigment, 1-3% of dispersing agent, 10-20% of organic solvent, 2-8% of antifoaming agent and 10-20% of water. The production technology comprises the following steps of: accurately preparing the raw materials according to the production formula proportion, stirring and dispersing, wherein the stirring time is 30-45 minutes; and then generally grinding for four times, and controlling the grain fineness at 10-15 micrometers after grinding. The invention provides a temperature change printing ink which is strong in high temperature resistance and adhesive force, and shows different colors with temperature rising or dropping.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a production process of temperature-changing ink. Background technique [0002] The existing anti-counterfeiting mark of the product has important guarantee significance for the quality of the product, and is an important means for consumers to distinguish the authenticity of the product. At present, products on the market generally adopt technical means such as laser anti-counterfeiting and printing anti-counterfeiting. The traditional printing anti-counterfeiting process is complicated, and its anti-counterfeiting means are single, such as gravure printing, rainbow printing, pattern butt joint, invisible image, etc., which are easy to be imitated and lose the anti-counterfeiting function. Also in the food industry, the traditional sterilization process is mainly used, so that the temperature-changing ink cannot be used on the outer packaging of products in the food and bevera...
