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 water-based polishing oil and discloses water-based polishing oil with an antibacterial function. The water-based polishing oil is prepared from nano-titanium dioxide modified water-based acrylic resin liquid, water-based resin liquid B, water-based wax emulsion, deionized water, ethanol, a defoaming agent, a flatting agent and a buffer agent. The process for preparing the water-based polishing oil comprises the following steps: preparing silane coupling agent modified inorganic nanoparticles by using nano-titanium dioxide, ethanol, deionized water and a silane coupling agent; preparing the nano-titanium dioxide modified water-based acrylic resin liquid by using an acrylic monomer, the silane coupling agent modified inorganic nanoparticles, polyethylene glycol, a water-soluble initiator, an emulsifier, ammonium hydroxide and deionized water; and preparing the water-based polishing oil from the nano-titanium dioxide modified water-based acrylic resin liquid, water-based resin liquid B, water-based wax emulsion, tea saponin, deionized water, ethanol, a defoaming agent, a flatting agent and a buffer agent. The water-based polishing oil has the advantages of no toxicity, no hazard, good dispersion and strong antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of water-based varnish, in particular to a water-based varnish with antibacterial function. 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-based varnish itself i...
