Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to an environment-friendly nanometer metallic silver antibacterial coating with good antibacterial properties and a preparation method thereof. Background technique: [0002] Architectural coatings have bright color, excellent quality, convenient construction, easy renovation, light weight, and low price. They are indispensable raw materials in the architectural decoration industry and are closely related to people's lives. [0003] There are various harmful microorganisms in people's living environment, which have a negative impact on human life, especially in some humid places in the home environment (such as kitchens, bathrooms, etc.) Bacterial concentration increased. [0004] With the continuous improvement of people's health awareness, the market has put forward higher requirements for architectural coatings: architectural coatings must also have antibacterial properties...
