Abstract

The invention discloses a long-acting silyl nano antibacterial agent and a preparation method thereof in the field of antibacterial agents. The long-acting silyl nano antibacterial agent is prepared from the following raw materials: trialkoxysilyl, nano titanium dioxide, nano silicon dioxide, nano zinc oxide, nano silicate, a silane coupling agent, ethanol, methyl benzene and an activating agent. According to the invention, the trialkoxysilyl group and the silane coupling agent are adopted, so that the anti-adhesion performance among nano titanium dioxide, nano silicon dioxide, nano zinc oxide and nano silicate can be improved, and the water resistance and weather resistance of the antibacterial agent can be enhanced, so that the product can be almost applicable to the surface of any object, an antibacterial protection layer is effectively formed, and viruses and bacteria can be killed for 90 days.

Description

technical field [0001] The invention relates to the field of antibacterial agents, in particular to a long-acting silane-based nano-antibacterial agent and a preparation method thereof. Background technique [0002] Antibacterial agents refer to a class of agents used to prevent and control plant diseases caused by various pathogenic microorganisms. Agents that can kill or inhibit the growth of pathogenic microorganisms without hindering the normal growth of plants. Fungicides can be classified according to their mode of action, source of raw materials, and chemical composition. Internationally, it is usually used as a general term for agents to prevent and control various pathogenic microorganisms. With the development of fungicides, subclasses such as bactericides, virucides, and algicides are distinguished. [0003] With the rapid development of nanotechnology, new ways to efficiently eliminate extracellular and intracellular pathogenic bacteria have gradually appeared...
