The invention discloses a stirring reactor and a coating method based on titanium dioxide gas phase coating. It includes a pipeline system, a reaction chamber and a test control system; the reaction chamber includes a cylinder, a heating element is arranged outside the cylinder, and a pipeline system and agitator for feeding and/or air intake are arranged on the cylinder. In the present invention, the titanium dioxide powder is fully disturbed and fully contacted and reacted with the gas precursor through high-speed stirring, so that the surface of the titanium dioxide can be covered with an inert layer, thereby improving the weather resistance of the titanium dioxide and realizing the enlargement of the gas-phase coating process of the titanium dioxide. , to obtain a product that can be used in the next step. |
