Abstract
Provided are an abrasion-resistant, stable and flame-resistant superhydrophobic/superoleophobic coating, and a preparation and application thereof, belonging to the field of new materials; the preparation includes: taking a superhydrophobic/superoleophobic suspension as a top-layer spraying solution; dispersing epoxy resin in a solvent, and adding a fluorine-containing curing agent and a flame retardant for reaction to obtain a bottom-layer spraying solution; and first spraying the bottom-layer spraying solution to a surface of a substrate, then spraying the top-layer spraying solution, and drying the surface to obtain a bilayer abrasion-resistant superhydrophobic flame-resistant coating; the superhydrophobic/superoleophobic suspension contains multi-level micro nano structural particles, a fluorine-containing curing agent and fluorinated epoxy resin; the prepared single-layer coating and bilayer structure (BLC) have hydrophobicity, flame resistance, good mechanical properties and excellent corrosion resistance performance.
