Preparation method of nano silicon dioxide silver-loaded antibacterial material

The invention relates to the technical field of preparation methods of chemical products, in particular to a preparation method of a nano-silica silver-loaded antibacterial material, which comprises the following steps: preparing a soluble silver nitrate and glucose solution; preparing water glass; carrying out reaction synthesis; washing the mixture through a plate frame; carrying out spray drying; and carrying out crushing package. The beneficial effects of the invention are that: the silicon dioxide nanoparticles generated by the preparation method disclosed by the invention are uniform insize and have a regular secondary aggregate structure; nano-silica prepared by a gel sol method is used as a network skeleton, soluble silver ions are adsorbed in the porous and rich skeleton of the nano-silica, and an AgNO3 solution is reduced into nano-Ag particles by glucose under a high-temperature alkaline condition and adsorbed on the surface of the nano-silica to form nano-silver with uniform particles; in addition
