| Abstract |
Dimethylaminoethylmethacrylate as a tertiary amine and Dimethylsulfate as a cationizing agent were synthesized at a ratio of 1: 1.2, and quaternary ammonium salt was synthesized and used to synthesize an antimicrobial acrylic polymer through acrylate and emulsion polymerization.
To confirm the antimicrobial effect on various factors, 70g CCL nonwoven fabric was padded and confirmed by shaking flask method. Factors considered include pick-up amount, quaternary ammonium salt content, and C12 content.
First, according to the pick up amount, the higher the pick-up amount, the better the antimicrobial activity.
According to one report, the alkyl chain length of the quaternary ammonium salt was changed and the dodecyl compound was found to have the best antibacterial properties. Then, the contents of lauryl methacrylate with C12 were 0%, 10% and 20%, respectively. All of them showed 99.9% antibacterial activity.
Finally, the antimicrobial activity of the quaternary ammonium salt was confirmed, and the content of quaternary ammonium salt was 20%, 25% and 30%, respectively. All of them showed 99.9% antibacterial activity. |
