Abstract

The invention relates to an antibacterial combination and a preparation method thereof as well as application of the antibacterial combination in preparation of antibacterial paper. The antibacterial combination contains atractylodes oil and an inorganic silver antibacterial agent. The antibacterial combination disclosed by the invention is sprayed on the surface of a piece of proper paper to prepare the antibacterial paper; the antibacterial paper can be used as food packaging paper, tobacco tipping paper and the like.

Description

Technical field [0001] The invention belongs to the field of chemistry and chemical engineering, and specifically relates to an antibacterial composition, its preparation method and its use in the preparation of antibacterial paper. The antibacterial composition contains atractylodes stearin and an inorganic silver antibacterial agent. The antibacterial paper can be prepared by spraying the antibacterial agent on the surface of a suitable paper. The antibacterial paper can be used as food packaging paper, tobacco tipping paper, and the like. Background technique [0002] With the continuous improvement of people's research and understanding of environmental microorganisms, while using the benefits of microorganisms, they are also very vigilant about their harmfulness as pathogens. In the long river of human history, various infectious diseases of various sizes have been prevalent in different periods and in different regions. These diseases have seriously threatened the survival ...
