Problems solved by technology

[0006] The disadvantage of the above two products is that the antibacterial ingredients are only physically mixed with other ingredients. Although they have an antibacterial effect, the dispersibility and effect are 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-soluble varnish and discloses a preparation method of water-soluble varnish containing Ag-carrying sepiolite. The preparation method comprises the following steps: (1) preparing Ag-carrying sepiolite; (2) compounding silane coupling agent modified Ag-carrying sepiolite with a water-soluble resin liquid A and a water-soluble resin liquid B and then compounding a mixed resin liquid with deionized water, ethanol, tea saponin, water-soluble wax emulsion, a defoaming agent, a levelling agent and a buffer agent, thus preparing the water-soluble varnish containing Ag-carrying sepiolite. The preparation method has the beneficial effects that containing various antibacterial components, such as nano-silver, titanium dioxide and tea saponin, the water-soluble varnish 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-soluble varnish is quite outstanding.

Description

technical field [0001] The invention relates to the technical field of water-based varnish, in particular to a preparation method of water-based varnish containing silver-loaded sepiolite. Background technique [0002] As a new green printing material, water-based varnish is widely used in the printing of food packaging, pharmaceutical packaging, cigarette packs, books, calendars, etc. Water-based varnish has excellent surface gloss, because its solvent is mainly water, not It will emit harmful volatile gases into the atmosphere, which is more environmentally friendly and conforms to the current concept of promoting environmental protection and health. Therefore, water-based varnish has a broad space for development in the future. [0003] For water-based varnish used in areas with high hygienic requirements such as cigarette packs, medical packaging, food packaging and printing, the water-based varnish itself is required to be non-toxic and harmless. However, although the...
