| 摘 要： | 采用离子交换法制备了载银沸石抗菌剂,并在质量分数为2%的PVA中添加不同浓度的载银沸石抗菌剂,制备了抗菌牛皮纸,研究了不同抗菌剂添加量下抗菌牛皮纸的厚度和定量的变化及抑菌与防霉效果。结果表明:制得的载银沸石中银离子含量较高,且沸石的基本结构未被破坏;添加载银沸石使纸张的厚度和定量略有增大,且当100mL质量分数为2%的表面施胶剂中载银沸石的添加量为0.5g时,抗菌牛皮纸对大肠杆菌的抗菌率达到99.94%,并能有效抑制黑曲霉菌的生长。

| Abstract: | silver-loaded zeolite antibacterial agent was prepared by ion-exchanging method,and different concentrations of silver-loaded zeolite were added into 2%(w/w)PVA solution to prepare antibacterial kraft paper.Thickness and quantities,antibacterial and antifungal properties of antibacterial kraft papers were studied respectively.The results showed that the content of silver in silver-loaded zeolites is high and the structure of zeolite isn’t damaged;the addition of antibacterial agent has a little effect on the thickness and quantity of kraft paper;when the addition of silver-loaded zeolite in 100ml 2%(w/w)surface sizing agent is 0.5 g,antibacterial rate of the antibacterial kraft paper to E.coli is up to 99.94% and the growth of aspergillus niger can be inhibited effectively. |
