Abstract

The invention provides a super-hydrophobic anticorrosive paint and a preparation method thereof, and belongs to the technical field of chemical paints, and the super-hydrophobic anticorrosive paint is a super-hydrophobic surface layer generated by an anticorrosive paint prepared from fluorocarbon resin and long-chain silane, so that the contact angle of water is greater than or equal to 150 degrees, the thickness exceeds 50 microns, and the super-hydrophobic anticorrosive paint has relatively strong durability; and the super-hydrophobic effect is achieved on the whole, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a super-hydrophobic anti-corrosion coating and a preparation method thereof. Background technique [0002] The anti-corrosion work of metal components and concrete components is more important. For example, if the oil casing, oil pipe and drill pipe are corroded and damaged, it will lead to serious consequences, and even the entire oil well will be scrapped, resulting in high economic losses. However, when the existing anti-corrosion paint encounters water vapor condensation, the water film will spread on the surface, and the corrosive media such as ions and oxygen in the water film will penetrate to the substrate through the paint film, causing the anti-corrosion effect to be greatly weakened. [0003] In the prior art, techniques such as template method, phase separation method, soft etching method, chemical vapor deposition method, electrospinning method and self-ass...
