复配抗菌剂对紫外光固化抗菌涂料性能的影响

摘要

采用紫外光固化技术，以自制抗菌剂三丁基对乙烯基苄基氯化鏻（DA）与甲基丙烯酰氧乙基十二烷基二甲基溴化铵（VP）复配作为抗菌单体，制备了紫外光固化抗菌涂料.研究了抗菌单体对固化膜性能的影响，并测试了紫外光固化抗菌涂料的理化性能和抗菌性能.结果表明：抗菌单体对固化膜性能有显著影响；当DA/VP用量比为0.4时，固化膜硬度、附着力和抗冲击性均能达到最佳；制备的紫外光固化抗菌涂料具有良好的抗菌性能，其各项理化性能均达到国家或行业标准.%The UV curable antimicrobial coating was prepared by UV curing technology with tributyl vinyl benzyl phosphonium chloride(DA)and methyl acryloyloxyethyl dodecyl dimethyl ammonium bromide(VP)as antibacterial monomer. The effect of antibacterial monomer ratio on the properties of the cured film was studied. The antibacterial properties and the physical and chemical properties of the UV cured coatings were tested. The results showed that the antibacterial monomer has a significant influence on the properties of cured film. When the amount of DA/VP ratio is 0.4,curing film hardness,adhesion,impact resistance and gloss can reach the optimum. The prepared UV curable antimicrobial coatings have excellent antibacterial properties ,and the physical and chemical properties have reached the national standard or industry standard.
