Problems solved by technology

But the disadvantage is that titanium dioxide and other ingredients are only physically mixed, although it has an antibacterial effect, but the dispersion is average
The water-based ink for smoking water pine paper of the invention has the advantages of small fineness, fast drying speed, high consistency, low viscosity, good dispersion stability, no induration precipitation, no coagulation, no residual odor, etc., but the invention uses the fungicide directly Mixed into water-based ink, although the bactericide can play a bactericidal effect, but the bactericidal broad-spectrum of a single bactericide is small, the bactericidal effect is limited, and it may also be harmful to the human body and cause side effects

Abstract

The invention relates to the technical field of water-based ink and discloses a preparation method of water-based ink, containing an Ag-carrying chitosan composite antibacterial material, for tipping paper. The preparation method comprises the following steps: (1) preparing Ag-carrying chitosan; (2) compounding Ag-carrying chitosan with a water-based resin liquid A and a water-based resin liquid B and then compounding a mixed resin liquid with deionized water, ethanol, tea saponin, an organic pigment, a defoaming agent, a levelling agent and a buffer agent, thus preparing the water-based ink, containing the Ag-carrying chitosan composite antibacterial material, for tipping paper. The preparation method has the beneficial effects that containing various antibacterial components, such as nano-silver, chitosan, titanium dioxide and tea saponin, the water-based ink prepared by the preparation method has strong bactericidal broad-spectrum property; the bactericidal components have synergistic effects, so that the bactericidal effects are greatly enhanced; the dispersibility of the bactericidal components in the water-based ink is quite outstanding.

Description

technical field [0001] The invention relates to the technical field of water-based inks, in particular to a method for preparing tipping paper water-based inks containing silver-loaded chitosan composite antibacterial materials. Background technique [0002] Tipping paper, also known as "tipping paper", is one of the important materials for producing cigarettes. It uses pine base paper as the base material, and is a special industrial paper that connects filter tips and cigarettes through pre-press design, printing processing and post-press processing. Since the tipping paper is in direct contact with the lips during use, the paper of the tipping paper and the ink printed on the tipping paper must be non-toxic and harmless to the human body. Because solvent-based ink contains a large amount of organic volatile solvents, it is not only harmful to the human body, but also not conducive to environmental protection, because water-based ink has gradually received more and more a...
