The invention belongs to the technical field of antibacterial ceramics, and particularly relates to an antibacterial ceramic and a preparation method thereof. The antibacterial ceramic disclosed by the invention is composed of a green body and an antibacterial coating, the green body is prepared from the following raw materials: pyrophyllite, cordierite, montmorillonite, wollastonite, magnesite, barite, cryolite, lithium chinastone, silicon nitride, boric sludge, nano lanthanum oxide and nano zinc phosphate; the antibacterial coating is prepared from the following raw materials: graphene oxide, modified red mud, 2-bromo-2-nitropropane-1, 3-diol, polyvinylidene fluoride, N-methyl pyrrolidone and perfluorodecyl triethoxy silane. According to the antibacterial ceramic disclosed by the invention, the mixture of the silicon nitride, the boric sludge, the nano lanthanum oxide and the nano zinc phosphate is additionally added into the green body layer, so that the green body has lasting antibacterial property. In addition, the hydrophobic antibacterial coating is arranged on the green body, so that the prepared ceramic has the advantages of bacterial adhesion reduction and antibacterial activity.
本发明属于抗菌陶瓷技术领域，具体的涉及一种抗菌陶瓷及其制备方法。本发明所述的抗菌陶瓷，由坯体和抗菌涂层组成；所述坯体，由以下原料组成：叶腊石、堇青石、蒙脱土、硅灰石、菱镁矿、重晶石、冰晶石、锂瓷石、氮化硅、硼泥、纳米氧化镧、纳米磷酸锌；所述抗菌涂层，由以下原料组成：氧化石墨烯、改性赤泥、2‑溴‑2‑硝基丙烷‑1,3‑二醇、聚偏二氟乙烯、N‑甲基吡咯烷酮、全氟癸基三乙氧基硅烷。本发明所述的抗菌陶瓷，坯体层中额外添加的氮化硅、硼泥、纳米氧化镧和纳米磷酸锌的混合物，使得坯体具有持久抗菌性。此外，通过在坯体上设置疏水的抗菌涂层，使得制备的陶瓷具有减少细菌粘附性和抑菌性。
