NOVELTY - Preparing rod-shaped zinc oxide-based composite photocatalytic antibacterial aqueous interior wall paint involves weighing the zinc oxide zinc source and dissolving it in ultrapure water, controlling the precipitation of zinc-ammonia complex by adding an aqueous ammonia solution, and then separating the precipitate by suction filtration, and then fully washing the precipitate with ultrapure water and absolute ethanol, and drying in a constant temperature drying oven to obtain zinc oxide-based composite photocatalytic particle precursor solution. 6mg/ml Solution of photocatalytic nanoparticles attached to the zinc ammonia complex precipitate is added, 6-8mol/l precursor solution is configured with ammonia water and ultrapure water, and sonicated for 30 minutes and dispersed sufficiently to obtain a precursor solution of zinc oxide-based composite photocatalytic particles. USE - Method for preparing rod-shaped zinc oxide-based composite photocatalytic antibacterial aqueous interior wall paint. ADVANTAGE - The method enables to prepare rod-shaped zinc oxide-based composite photocatalytic antibacterial aqueous interior wall paint with high safety and good mechanical properties in an eco-friendly manner. DETAILED DESCRIPTION - Preparing rod-shaped zinc oxide-based composite photocatalytic antibacterial aqueous interior wall paint involves weighing the zinc oxide zinc source and dissolving it in ultrapure water, controlling the precipitation of zinc-ammonia complex by adding an aqueous ammonia solution, and then separating the precipitate by suction filtration, and then fully washing the precipitate with ultrapure water and absolute ethanol, and drying in a constant temperature drying oven to obtain zinc oxide-based composite photocatalytic particle precursor solution. 6mg/ml Solution of photocatalytic nanoparticles attached to the zinc ammonia complex precipitate is added, 6-8mol/l precursor solution is configured with ammonia water and ultrapure water, and sonicated for 30 minutes and dispersed sufficiently to obtain a precursor solution of zinc oxide-based composite photocatalytic particles. The composite precursor solution and the components of the water-based interior wall paint are sequentially mechanically stirred and mixed in a reaction kettle to obtain a mixed coating. The microwave reaction synthesis of the mixed paint is performed to obtain rod-shaped zinc oxide-based composite photocatalytic particle antibacterial waterborne interior wall paint.
