Description

technical field [0001] The invention relates to the technical field of iron and steel, in particular to a hydrophobic composite material. Background technique [0002] CN201510552308.1 discloses a hydrophobic anti-corrosion dacromet coating and a preparation method thereof, belonging to the technical field of metal anti-corrosion. It is composed of surface-modified scaly zinc and aluminum powder, organic solvent, film-forming aid, hydrophobic nano-sol and hydrophobic nano-powder; in the total weight of 100%, zinc powder accounts for 18-23%, aluminum powder accounts for 2 ~4.5%, hydrophobic nano-sol accounts for 34-42%, hydrophobic nano-powder accounts for 0.8-3.5%, film-forming aid accounts for 0.4-0.9%, and solvent accounts for 33-40%. The invention makes the surface of the dacromet coating exhibit hydrophobicity through the hydrophobic nano sol and nano powder, and improves the anti-corrosion performance. The technical scheme is to disperse the zinc-aluminum powder modif...
