Abstract
A method for preparing a natural antibacterial agent by utilizing attapulgite pore channels to immobilize plant essential oil. Natural antibacterial agent plant essential oil is sprayed on the surface of attapulgite powder while stirring, after mechanically grinding the materials, a liquid glycerol monolaurate and quaternary ammonium salt aqueous solution are sequentially sprayed, after uniformly stirring and mixing the materials, a mixture is extruded by using an extruder, and drying, crushing and packaging are performed.
