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, it may also be harmful to the human body and cause side effects

Abstract

The invention relates to the technical field of waterborne gloss oil and discloses a method for preparing compound antibacterial waterborne gloss oil. The method comprises the following steps: (1) preparing a silane coupling agent modified halloysite nanotube; (2) preparing a silver-loaded halloysite nanotube; and (3) combining the silver-loaded halloysite nanotube with a waterborne resin liquid A and a waterborne resin liquid B, compounding the mixed resin liquid with a waterborne wax emulsion, deionized water, ethanol, tea saponin, a defoamer, a flatting agent and a buffer agent to obtain the compound antibacterial waterborne gloss oil. The waterborne gloss oil prepared by the invention contains various antibacterial components such as nano-silver, titanium dioxide and tea saponin so that the waterborne gloss oil has strong antibacterial broad spectrum; due to the synergistic effect of each antibacterial component, the antibacterial effect is greatly reinforced and the dispersibility of each antibacterial compound in the waterborne gloss oil is excellent.

Description

technical field [0001] The invention relates to the technical field of water-based varnish, in particular to a method for preparing a composite antibacterial water-based varnish. 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 water-bas...
