NOVELTY - Cationic modified graphene antibacterial spray comprises 1-10 %mass cationic resin, 1-10 %mass modified graphene nano-silver solution, 1-10 %mass nano titanium dioxide, 75 %mass ethanol, 0.1-5%mass additive agent and remaining is deionized water. USE - The antibacterial spray is used in application such as public toilets, shopping malls, schools, and farms. ADVANTAGE - The antibacterial spray has excellent antibacterial effect, and excellent lasting antibacterial property and does not produce offensive odor during the spraying process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the cationic modified graphene antibacterial spray involving adding ethanol and deionized water to a container, adding the cationic resin, the modified graphene nano-silver solution, nano-titanium dioxide and the additive agent while stirring at a rotating speed of 300-1000 rpm, continuing to stir for 30-120 minutes after all the addition, and leaving still for 12 minutes to 24 hours and obtaining the cationic modified graphene antibacterial spray.
