In the process of making some products, it is necessary to add an appropriate amount of antimicrobial agent, mainly to improve the ability of the product to resist microbial erosion. In order for the antimicrobial agent to function effectively to prevent microbial growth on the surface of the polymer, the added dose should be sufficient to migrate to the surface of the polymer.
That is, a certain amount of antimicrobial agent has a positive effect on extending the useful life of the article. This series of products has the advantages of good storage stability, good compatibility with pigments, and low shipping cost. At present, according to the way of obtaining phenolic hydroxyl groups, the synthetic process of antimicrobial agents can be divided into different process methods, mainly including the following:
The first one is the diazotization process, that is, the corresponding diazonium salt is first prepared, and then the diazonium salt is hydrolyzed to obtain an antimicrobial agent; the second is called a transesterification process, and the ester of the antimicrobial agent is first obtained, and then Transesterification with an alcohol to obtain an antimicrobial agent; third, a peroxidic compound prepared with an antimicrobial agent, and then hydrolyzed under certain conditions to obtain an antimicrobial agent; and fourth, an ether compound of an antimicrobial agent is fixed Dealkylation under conditions provides a dealkylation process for the antimicrobial agent.
