Problems solved by technology

[0003] During the printing process of ink, static electricity will easily lead to poor printing effect
In order to reduce the harm caused by static electricity, people usually add antistatic additives to the ink to suppress the generation of static charge and promote the leakage of static charge. Antistatic additives can reduce the resistance of the ink, but at the same time the adhesion and brightness of the ink will decrease. , the printing effect is poor

Abstract

The invention discloses a preparing method of multifunctional water-based ink. The preparing method includes the steps that 1, half of waterborne polyurethane resin, an antibacterial composite material and conducting filler are added into a reaction kettle and stirred uniformly, and an emulsifying agent is added dropwise; temperature raising, heat preservation and temperature lowering are carried out, a dispersing agent and water-based pigment are added, and pigment slurry is prepared through grinding after the mixture is stirred uniformly and is filtered; 2, remaining waterborne polyurethane resin, water, neutralizer, cosolvent and a defoaming agent are added into the pigment slurry, the mixture is dispersed through a grinding miller, and when the fineness reaches 5 micrometers or below, the mixture is packaged to obtain water-based ink. The conducting filler and the antibacterial composite material are reasonably matched, and therefore the ink has conductivity and durable antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a multifunctional water-based ink and a preparation method thereof. Background technique [0002] With the enhancement of people's ecological awareness, the development and application of environmentally friendly materials have been paid more and more attention. Inks are developing in the direction of high-performance and environmentally friendly. Among them, water-based inks are mainly water-based and equipped with non-toxic water-based binders. Much favored by the printing industry. [0003] During the printing process of ink, static electricity will easily lead to poor printing effect. In order to reduce the harm caused by static electricity, people usually add antistatic additives to the ink to suppress the generation of static charge and promote the leakage of static charge. Antistatic additives can reduce the resistance of the ink, but at the same time the adhesion and brigh...
