Embodiment Construction
[0068] The present invention will be specifically described below with reference to the accompanying drawings and in combination with embodiments.
[0069] Such as Figure 1~6 Shown, the present invention adopts following steps to realize:
[0070] a) prepare the base material and the lining of the ceramic tile body according to the conventional method, and set aside;
[0071] b) preparing a nanocomposite photocatalytic functional material, the composite photocatalytic functional material comprising a nanocomposite photocatalytic powder, polyurethane and sodium carboxymethylcellulose-polyamine derivative aqueous solution; the specific preparation is as follows:
[0072] Prepare 0.5~1.0mol / L Na 2 WO 6 2H 2 O and 0.5-2.5mol / L Bi(NO 3 ) 3 ·5H 2 O, invert both into a container filled with 50vol% deionized water at the same time, and sonicate for 20min. After the ultrasound is over, centrifuge and wash the liquid in the beaker, put it in the reaction kettle, add 45-65vol% d...
