Problems solved by technology

[0004] 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 ink and accelerate the leakage of ink, but the adhesion of ink , the brightness will be reduced, and the printing effect will be poor

Abstract

The present invention relates to the technical field of ink, in particular to an antistatic water-based ink and a preparation method thereof, which consists of the following raw materials in parts by weight: 25-35 parts of toner, 30-40 parts of acrylic resin, and 1-4 parts of anti-wear agent , 0.5-1.5 parts of anti-scratch agent, 0.1-1 part of transfer agent, 0.1-0.6 part of defoamer, 26-35 parts of water. The present invention adopts conductive carbon black as toner, because conductive carbon black has more pores, it is easy to absorb impurity atoms such as H and O other than carbon atoms and obtain saturation, hindering the normal connection between carbon atoms, so that conductive carbon black has a lower Therefore, the present invention does not need to add antistatic additives to make the ink have better antistatic performance, and the conductivity of the ink is reduced to 500-700kΩ, and avoids the addition of antistatic additives to affect the adhesion and brightness of the ink. Influence, but also save the manufacturing cost of the product.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an antistatic 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] At present, in the packaging and printing industry, static electricity can easily lead to poor printing effect. When static electricity is generated during printing, it will easily lead to the following situations: ①The ink flies out of the edge of the printed pattern or text, in the shape of an irregular beard; ②When the depth of the plate is 5 ~20μm is prone to spotting on the actual printed p...
