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 conductive waterborne ink. The preparing method includes the following steps that 1, a half of waterborne polyurethane resin, a half of antibacterial composite materials and a half of conductive filler are added into a reaction kettle and stirred to be even, an emulsifying agent is dropwise added, heating, heat preservation and cooling are carried out, a dispersing agent and waterborne pigment are added, the mixture is stirred to be even, and then color paste is grinded, prepared and filtered; 2, the residual waterborne polyurethane resin, water, a neutralizing agent, a solubilizing assistant and an antifoaming agent are added into the color paste, the mixture is dispersed through a grinding miller, and when the fineness is 5 microns or below, packaging is carried out, and the waterborne ink is obtained. According to the preparing method, the conductive filler and the antibacterial composite materials are reasonably matched, and the ink has the conduction characteristic and further has the lasting antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a conductive 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 brightness ...
