The invention discloses a preparation method of a photocatalytic mite removing and antibacterial disinfectant, comprising the following steps: adding titanium trichloride into deionized water, ultrasonically dispersing, adding hydrochloric acid during the ultrasonic dispersing process, continuing ultrasonic dispersion, and adding metavanadic acid Sodium is stirred at high temperature, centrifuged, washed, dried, and calcined to obtain nano-powder; the nano-powder is added to sodium hydroxide solution, stirred evenly, hydrothermally reacted, washed to neutrality, then pickled, dried, under argon protection for 300 Heat treatment at ‑400℃ for 1‑2h to obtain composite nano-titanium dioxide powder; add graphene oxide to the ethanol aqueous solution for ultrasonic dispersion, add the composite nano-titanium dioxide powder to disperse evenly, hydrothermally react at 140‑180 ℃ for 20‑30h, and then add ten Sodium dialkylbenzene sulfonate, cocoyl diethanolamine, fatty alcohol polyoxyethylene ether, fatty alcohol polyoxyethylene ether sodium sulfate, plant essential oil, and water are mixed uniformly to obtain a photocatalytic acarid removal and antibacterial disinfectant. |
