Abstract

The invention relates to the technical field of printing ink, in particular to mildew-proof and antibacterial water-based printing ink for printing packaging cartons and a production method of the mildew-proof and antibacterial water-based printing ink. The printing ink comprises, by weight, 60-70 parts of water-soluble acrylic resin, 25-30 parts of a water-based pigment, 2-4 parts of isopropanol,0.1-0.3 part of chitosan, 0.5-1 part of cinnamon oil, 0.5-1 part of an antibacterial agent, 3-5 parts of a pH value stabilizer, 0.2-0.4 part of lauryl sodium sulfate, 0.2-0.4 part of a GPE defoamingagent, 3-5 parts of propylene glycol alginate and 45-55 parts of water. The water-based ink produced by the method has good antibacterial and mildew-proof effects, so that the antibacterial and mildew-proof capability of a packaging carton product printed by the water-based ink is improved, and the water-based ink is safe, environment-friendly, good in wear resistance and water resistance and lowin production cost, and can be widely applied to printing of outer packaging cartons of foods and the like.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a mildew-proof and antibacterial water-based ink for packaging carton printing and a production method thereof. Background technique [0002] With the development of social culture, science and technology, and economy, the printing industry is developing at an unprecedented speed.
