NOVELTY - Surface long-acting antibacterial and disinfectant composition includes component A, component B and auxiliary materials, where the component A, component B, and auxiliary materials are all inorganic components, and the component A is self-dispersed graphene and iron-doped nano titanium dioxide powder. The components of component A include titanium salt, alcohols, graphene and iron trichloride, and component B is small molecule water with acidic oxidation potential. USE - The agent is useful for indoor environment, long-acting antibacterial and antivirus, car interior environment, personal protection and hygiene, antibacterial and antifungal of buildings, etc. ADVANTAGE - The agent has good killing performance, one-time spraying, long-term effective, is safe and friendly, and is easy to transport and store. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing long-acting surface antibacterial and disinfectant, comprising: (i) (1) preparation of component A: (a) pumping the alcohol substance into the batching kettle through a metering pump, and stirring, and turning the jacket cooling water on to cool down; (b) pumping the titanium salt into the batching kettle through a metering pump, cooling while stirring, until the titanium salt and the alcohol are fully mixed and reacting; (c) adding quantitative graphene and quantitative ferric chloride; (d) stirring and reacting for 0.5-2 hours to obtain solution C; (e) transferring solution C into a special reactor, and heating the reactor through the jacket of the reactor, controlling at 100-400degrees Celsius, for 8-24 hours; (f) after the reaction is completed, passing through the reactor pressure generated by the reaction, releasing from the bottom valve of the reactor to the cyclone separator to realize the separation of gas and solid, collecting the solid powder by the bottom container of the separator to obtain self-dispersed graphene and iron-doped nano titanium dioxide powder, which is a group part A, the powder is monodisperse in the order of 5 nm, and the gas enters the tail gas treatment device, and is discharged after the treatment is qualified; (j) purging the residual powder in the reactor with nitrogen into the cyclone separator until the reactor is purged clean, the component A is further dried in a vacuum dryer to remove the volatile organic matter in the component A, the tail gas enters the tail gas treatment device, and is discharged after the treatment is qualified; (ii) preparation of component B: (h) allowing tap water passes through the RO reverse osmosis membrane treatment unit to remove ions in the water to obtain pure water, adding additives into the pure water and entering the electrolysis device to obtain acidic oxidation potential small molecule water, namely component B; (iii) preparation of surface long-acting antibacterial disinfectant: (i) adding component A, component B and auxiliary materials in a certain ratio in the batching kettle to obtain the surface long-acting antibacterial disinfectant of the final product, where the mass percentage is the component A: Component B: auxiliary material = 0.5-5%: 94-99%: 0.5%.
