Abstract

The invention provides a preparation method of large biological water-based gloss oil. The preparation method comprises diatomite modification and water-based gloss oil preparation. According to the large biological water-based gloss oil prepared by the preparation method disclosed by the invention, plant active ingredients are added, so that the inhibition rate on staphylococcus aureus is 95.2 to 95.6 percent, the inhibition rate on escherichia coli is 96.7 to 97.2 percent, the inhibition rate on pseudomonas aeruginosa is 95.6 to 96.4 percent, and the inhibition rate on candida albicans is 93.4 to 93.9 percent; the transparency is high, the glossiness is good, and the glossiness is 93-95%; and the wear resistance and the scratch resistance are high, the wear resistance times can reach 450-500 times or above when the paper product is coated with the gloss oil, and the hardness can reach 3H.

Description

technical field [0001] The invention relates to a method for preparing large biological water-based varnish, which belongs to the technical field of printing varnish. Background technique [0002] With the development of society, human beings' awareness of the protection of the living environment has also been continuously improved. For the printing industry, many requirements and constraints on hygiene, environmental protection, and labor protection have gradually increased, especially the requirements for food packaging and printing. More stringent, the only way to meet the requirements of international health standards. Therefore, it is imperative to develop and apply pollution-free and pollution-free "green" materials. Water-based varnish has the characteristics of non-toxic, odorless, high gloss, and convenient use. It has been widely used in the field of packaging and printing in recent years, and has achieved a rising trend. [0003] CN108385435B discloses water-bas...
