The development of the self-cleaning material is mainly to coat a layer of coating with self-cleaning performance and a certain anti-reflection effect on the surface of a base material, and titanium dioxide is commonly applied in the self-cleaning coating, and the surface of the self-cleaning coating can keep clean by utilizing sunlight and natural rainfall, so that the maintenance time, cost and energy can be saved, the air can be purified, and the environmental pollution can be reduced. Titanium dioxide has wide application in high-tech fields such as photocatalysis, sensors, solar cells, biomaterials and the like. Under the irradiation of light, the titanium dioxide has the functions of super-hydrophilicity, photocatalysis (organic matter decomposition), negative oxygen ion release and the like, namely the titanium dioxide has the self-cleaning function. The titanium dioxide self-cleaning function is applied to the aluminum plate, so that the cleaning problem can be solved, and the effect of naturally cleaning the aluminum plate can be achieved by rain wash and regular running water wash. However, in the prior art, when titanium dioxide is applied to a coating system, titanium dioxide has poor compatibility, and cannot fully exert the self-cleaning effect, and the self-cleaning effect is still greatly limited, so that the titanium dioxide is difficult to be really widely applied. In addition, the coating system has poor washing and brushing resistance, and the coating can generate color change and fall off after a short time, so that the surface of an object is rusted and corroded, and the like. And with the increasing urban environmental pollution, the dust pollution and the gas pollution are particularly serious, the comprehensive performance of the self-cleaning coating applied to doors and windows is reduced, and the service life of the base material is indirectly reduced in the application process.
