Indoor efficient antibacterial deodorant as well as preparation method and application thereof

The invention relates to the technical field of environmental protection, in particular to an indoor efficient antibacterial deodorant and a preparation method and application thereof.The indoor efficient antibacterial deodorant is prepared from a composite antibacterial agent, silver bromide-silver/nano silicon, hydrogel, a wetting agent, a defoaming agent and the balance water; the composite antibacterial agent is a trichoderma C4-position ester derivative and/or a copper-loaded zinc oxide nano material; the silver bromide-silver/nano silicon is formed by loading silver-silver bromide on a nano silicon wafer. The environment adaptability is extremely good, the antibacterial property is obvious under the conditions of natural light, weak light or no light, the broad-spectrum, efficient and rapid sterilization effect is achieved, the killing rate of most bacteria and viruses is 99% or above, and fungi are inhibited and cannot grow; under visible light, the excellent effects of decomposing formaldehyde and rem
