Abstract

The invention discloses a preparation method of antibacterial powders for an antibacterial coating. The preparation method comprises the following steps of: (1) weighing: weighing the prepared raw materials in parts by weight; (2) pouring a Na3PO4 gelatin solution into a reaction kettle, then, dropwise adding a silver nitrate solution, a copper nitrate solution and a zinc nitrate solution into the reaction kettle within 30min, adjusting the pH value to be between 6 and 7, then, adding triethyltin chloride and stirring to obtain a colloid; (3) deposition and filtration: depositing the obtained colloid for 2-3h, and then, filtering; (4), washing; (5) drying; and (6) calcining: calcining at the temperature of 70-90 DEG C for 2-3 hours to obtain Ag3PO4 powder, Ag3PO4-Zn3(PO4)2 powder, Ag3PO4-Cu3(PO4)2 powder and Ag3PO4-Cu3(PO4)2-Zn3(PO4)2 powder. The antibacterial powders provided by the invention can be favorably applied to the antibacterial coating, is environment friendly, free of pollution to human bodies and the environment, has high antibacterial rate of over 99.9% and is suitable for occasions such as a food factory, a pharmaceutical factory, a brewery, a hospital and the like with relatively high requirements on the environment.

Description

technical field [0001] The invention relates to an antibacterial material, in particular to a method for preparing antibacterial powder used for antibacterial coatings. Background technique [0002] Microorganisms can be found on almost all abiotic surfaces. There are also various types of microorganisms in other places, such as: medical care institutions; public places with high risk of infection: stations, hotels, hotels, airports; bathrooms in humid environments, hot springs and cooling towers. In the above sensitive areas, the so-called multi-drug resistance Bacteria and pathogenic bacteria (Gram-positive and negative bacteria), fungi have a tendency to grow, and the surfaces of places where bacteria grow can threaten human health. [0003] The existing antibacterial coating has poor antibacterial effect and short time, which is far from meeting the requirements of places with relatively high environmental requirements such as food factories, pharmaceutical factories, b...
