[0025] Example 1
[0026] Prepare a 1.5mol / L nitric acid aqueous solution, add propyl silicate to the above nitric acid solution at 50°C, the molar ratio of the added propyl silicate to nitric acid is 1:1.75, stir until it dissolves; under stirring conditions, Add titanium tetrachloride to the solution of step (b) dropwise in 35 minutes, add titanium tetrachloride to propyl silicate in a molar ratio of 1:1.75, continue to stir for 1 hour to obtain a new solution; The solution was transferred to the reaction kettle and reacted at 180°C for 30 hours; the product was dried at 200°C and then calcined at 400°C for 2 hours to obtain a titanium dioxide-silicon oxide composite oxide; 20% by mass Fractional ATO powder is melted and blended into the titanium dioxide-silicon oxide composite oxide at 150 DEG C to 250 DEG C to obtain an environmentally friendly nano coating material.
