| titleOfInvention | Preparation method of gemini quaternary ammonium salt polyurethane coating material with antibacterial property |
| abstract | The invention discloses a preparation method of a gemini quaternary ammonium salt polyurethane coating material with antibacterial property, which is characterized by synthesizing a di-tertiary amine monomer containing double bonds through nucleophilic substitution reaction of secondary amine and acyl chloride, then entering dihydroxyl into the di-tertiary amine monomer by utilizing Michael addition reaction of sulfydryl-double bonds to obtain a dihydroxyl di-tertiary amine monomer, adding halogenated alkane or halogenated fluorine-containing alkane to quaternize two tertiary amines in the dihydroxyl di-tertiary amine to obtain a gemini quaternary ammonium salt diol monomer, then introducing the gemini quaternary ammonium salt diol into polyurethane in the form of a chain extender at the molecular level through addition polymerization reaction of the gemini quaternary ammonium salt diol and a polyurethane prepolymer, and finally obtaining the gemini quaternary ammonium salt polyurethane coating material with antibacterial property through chain extension reaction. The disclosed Gemini quaternary ammonium salt polyurethane coating material has good biocompatibility, film forming property and antibacterial property, and can be widely applied to the fields of biomedicine, leather finishing agent, food packaging, water treatment and the like. |
