The invention belongs to the technical application field of diatom plates, and particularly relates to a diatom plate with an antibacterial function and a preparation method thereof.The diatom plate is prepared from 30-55 parts of diatomite, 16-25 parts of cement, 8-12 parts of kaolin, 10-15 parts of quartz sand, 10-15 parts of resin, 8-10 parts of Ag-doped SiO2 nanofiber, 4-6 parts of calcium sulfate whisker, 2-3 parts of polyethylene wax, 1-3 parts of dispersing agent and 1-10 parts of chemical additive. 0.1-2 parts of a thickening agent; and 1-3 parts of a defoaming agent. The diatom plate manufactured by utilizing a specific formula has the characteristic of excellent antibacterial property, the Ag-doped SiO2 nanofibers are added, and released ions have high reactivity through reasonable matching of the Ag-doped SiO2 nanofibers and the diatomite and can be combined with tissue protein, so that the structures of bacterial cell walls and nuclear membranes are changed, the inside and the outside of the membranes cannot be normally polarized, and the antibacterial property of the diatom plate is improved. Molecular transport required for maintaining normal operation of cells is hindered, so that the cells are lack of nutrients, and cell deformation and death are caused. Meanwhile, bacteria DNA and RNA can be combined through denaturation, bacteria replication is inhibited, and most of cells in microorganisms are killed, so that the antibacterial effect is improved, the use range of the material is widened, a new material is provided for hospitals and purified rooms, the problems that an existing antibacterial material is heavy, fragile, much in construction waste and the like are solved, the antibacterial value is indirectly increased, and the application prospect is wide. The composite material can be widely applied to the fields of indoor decoration, environmental protection, energy conservation, daily necessities and the like.
本发明属于硅藻板技术应用领域，具体一种具有抗菌功能的硅藻板及其制备方法，其组成成分包括：硅藻土30‑55份，水泥16‑25份，高岭土8‑12份，石英砂10‑15份，树脂10‑15份，Ag掺杂SiO2纳米纤维8‑10份，硫酸钙晶须4‑6份，聚乙烯蜡2‑3份，分散剂1‑3份，化学添加剂1‑10份，增稠剂0.1‑2份和消泡剂1‑3份。利用特定配方制造的硅藻板，具有抗菌性能优良的特点，其中添加Ag掺杂SiO2纳米纤维，通过Ag掺杂SiO2纳米纤维和硅藻土的合理搭配，释放的离子具有高度反应性，其可以与组织蛋白质结合并使细菌细胞壁和核膜的结构发生变化，膜内外不能正常极化，阻碍维持细胞正常运转所需的分子运输，使得细胞缺少养分，导致细胞变形和死亡。同时还可以通过变性结合细菌DNA和RNA并抑制细菌复制，杀死微生物体内的大多数细胞，进而加大抗菌效果，提高了材料的使用范围，使医院和净化房间又有了新的材料，解决了现有抗菌材料笨重，易碎，建筑垃圾多等问题，也间接提高了抗菌数值，可广泛应用室内装饰与装修、环保、节能以及日常生活用品等领域。
