Abstract

The invention provides antibacterial, mildew-proof and antiviral porous ceramic. The surface of the antibacterial, mildew-proof and antiviral porous ceramic is coated with antibacterial glaze; and the antibacterial glaze comprises an inorganic silver-loaded antibacterial agent, nano zinc oxide, a binder and a ceramic glaze. The inorganic silver-carrying antibacterial agent and the nano zinc oxide are added into the ceramic glaze to prepare the antibacterial glaze, the surface of the porous ceramic is coated with the antibacterial glaze, and the inorganic silver-carrying antibacterial agent, the nano zinc oxide, the binder and the ceramic glaze are fully mixed in a reasonable proportion. The prepared antibacterial glaze not only has excellent antibacterial, mildew-proof and antiviral performance, but also has a sound flowing state, so that the antibacterial, mildew-proof and antiviral porous ceramic not only has antibacterial performance, but also can adsorb microorganisms such as pathogenic bacteria, fungi and viruses through the porous structure, and the effect of purifying air or water is achieved.

Description

technical field [0001] The invention belongs to the technical field of antibacterial, mildew-proof and anti-virus ceramics, and relates to an anti-bacterial, mildew-proof and anti-virus porous ceramic and its preparation method and application. Background technique [0002] In daily life, microorganisms such as various pathogenic bacteria, fungi, and viruses may exist in the air, water bodies, and surfaces in contact with objects. When the human body comes into contact with pathogenic microorganisms or drinks water contaminated by pathogenic microorganisms, it is easy to cause a variety of diseases and seriously threaten human health. Therefore, it is very important to effectively remove pathogenic microorganisms in water. [0003] R & D workers have developed a variety of antibacterial materials, including organic antibacterial materials, inorganic antibacterial materials and natural antibacterial materials. Among them, inorganic antibacterial materials have the character...
