利用自制的纳米抗菌SiOx颗粒制备了PVC/季铵盐(Q)-SiOx纳米抗菌复合材料,研究了材料的抗菌效果、力学性能及抗菌长效性。结果表明,Q-SiOx质量分数为1%的材料抗菌率达到90%左右,抗菌率高于相同含量的锌系抗菌材料;与未添加Q-SiOx的材料相比,其拉伸强度和冲击强度分别提高了66.3%和124.1%,且均优于同条件下制备的金属离子型抗菌材料;放置一年并加速老化后的材料基本保持了原有的抗菌性能。
PVC / quaternary ammonium salt (Q) -SiOx nano-antibacterial composite was prepared by self-made nano-antibacterial SiOx particles. The antibacterial effect, mechanical properties and antibacterial long-term effect of the material were studied. The results showed that the antibacterial rate of Q-SiOx with the mass fraction of 1% was about 90% and the antibacterial rate was higher than that with the same content of zinc antibacterial material. Compared with the material without Q-SiOx, the tensile strength and impact strength Respectively, increased by 66.3% and 124.1%, respectively, and were better than those prepared under the same conditions of ionic antibacterial materials; placed one year and accelerated aging of the material basically maintained the original antibacterial properties.
