Abstract

The invention discloses a polymerizable rosin quaternary ammonium salt bactericide, a preparation method thereof, and a polymerized rosin quaternary ammonium salt bactericide prepared from the polymerizable rosin quaternary ammonium salt bactericide. The structural formula of the polymerizable rosin quaternary ammonium salt bactericide is shown in the specification. The polymerizable rosin quaternary ammonium salt bactericide has good biocompatibility and efficient bactericidal property, and also has polymerizable active groups; and the preparation method of the polymerizable rosin quaternaryammonium salt bactericide develops the novel efficient bactericide from natural biomass resource rosin, provides a new way for high-valued utilization of the rosin resource, and ha a simple synthesisprocess.

Description

technical field [0001] The invention relates to a polymerizable rosin quaternary ammonium salt bactericide, a preparation method thereof and a polymerized rosin quaternary ammonium salt bactericide, belonging to the field of novel bactericides. Background technique [0002] In recent years, cationic fungicides based on quaternary ammonium compounds have been developed with high-efficiency and broad-spectrum bactericidal properties, and have been widely used in various fields such as biomedical materials, water purification systems, and food storage. Its mechanism of action is that cations adsorb negatively charged bacteria through electrostatic forces, hydrogen bonds, etc., and gather on the cell wall, resulting in a room resistance effect, inhibiting the growth of bacteria and causing them to die; at the same time, the hydrophobic alkyl group can also change the permeability of the membrane. Permeability, followed by lysis, destroys the cell structure, causing cell lysis an...
