研究了自制ZnO/Ag纳米复合抗菌剂的亲油改性,利用改性后的ZnO/Ag纳米复合抗菌剂制备天然橡胶(NR)纳米复合材料,探讨了抗菌NR纳米复合材料的抗菌、抗藻性能。结果表明:ZnO/Ag纳米复合抗菌剂经磷酸三丁酯(TBP)改性后,沉降率从接近1减小到0.2以下,亲油性和稳定性大大提高,将TBP改性后的抗菌剂加入到油性介质正己烷中,抗菌剂分散均匀,粒径在100nm以内;在NR纳米复合材料的制备中,随着ZnO/Ag纳米复合抗菌剂添加量的增加,正硫化时间减小;经检测,抗菌NR纳米复合材料对大肠埃希氏菌的抗菌率达98%以上,且抗菌率随抗菌剂添加量的增加而增大,抗藻性能达到最优零级标准。
The self-made ZnO / Ag nanocomposite antibacterial agent lipophilic modification of the use of modified ZnO / Ag nanocomposite antibacterial agent preparation of natural rubber (NR) nanocomposites, discussed the antibacterial NR nanocomposites antibacterial, anti-algae performance. The results showed that the rate of lipophilicity and stability of ZnO / Ag nanocomposite antibacterial agent modified by tributyl phosphate (TBP) decreased from nearly 1 to below 0.2, and the TBP modified antibacterial agent was added To the oily medium n-hexane, the antibacterial agent dispersed evenly, the particle size of less than 100nm; NR nanocomposite preparation, with the addition of ZnO / Ag nanocomposite antibacterial agent decreases, the positive curing time decreases; After testing, Antibacterial NR nanocomposites antibacterial rate of Escherichia coli over 98%, and the antibacterial rate increases with the addition of antibacterial agent, anti-algae properties to achieve the optimal zero-scale standards.
