Abstract
A superhydrophobic coating is provided and contains organosilane, an inorganic nanomaterial, and an emulsifying agent. A mass proportion of the components is controlled, so that the superhydrophobic coating can form a micro-nano mixed microstructure inside foam concrete. The organosilane first forms dense hydrophobic surface layers on the surface and in inner pores of the foam concrete, and the nanomaterial forms uniformly distributed nano-bulges on the hydrophobic surface layers formed by the silane. The superhydrophobic performance of the foam concrete can be effectively improved by combining the two microstructures. The foam concrete exhibits excellent superhydrophobic performance.
