| Abstract |
In general, the antibacterial agent applied to the antibacterial filter for air cleaners is mainly composed of a low-molecular type substances. As time elapses, the antimicrobial effect deteriorates due to the desorption, and the desorbed substances spreads into the air, which has a bad influence on health.
To solve this problem, a quaternary ammonium salt acrylic polymer was applied to an antibacterial filter. Acrylic polymers with fixed strength are slow to release and thus have an continuous antibacterial effect. It is well known that quaternary ammonium salts are cationic and have an antibacterial effect.
First, to synthesize the quaternary ammonium salt was used DMAEMA (2-Dimethylaminoethylmetacrylate) as the tertiary amine and DMS (Dimethylsulfate) as the cationic agent. The reaction between DMAEMA and DMS was exothermic and showed the highest yield of 96.5% at reaction ratio (DMS / DMAEMA) of 1.2 and reaction temperature of 45 ℃.
Quaternary ammonium salt acrylic polymers were synthesized by emulsion polymerization using DMAEMA-DMS of 18.0% , Ethyl acrylate of 11.0% , Glycidyl methacrylate of 4.0% , Acrylic acid of 2.0%, Methyl methacrylate of 2.5%.
The synthetic quaternary ammonium acrylate polymer showed 99.9% antibacterial activity against Staphylococcus aureus and Pneumococcus by the shaking flask method. |
