Research and preparation of superhydrophobic coating and its application in the equipments of pump station

For the Mohe-Daqing Oil Pipeline and pump station equipments, the surface temperature is lower than ambient temperature from the early spring to the late autumn, severe condensate water corrosion will be caused in a very wet environment. Hence, a kind of anti-corrosive superhydrophobic coating is developed. The coating is simple to paint and easy for large-area application. It is to form rough-surface hydrophobic coating by simple one-step mixing with inorganic nanoparticles and fluoride acrylic resin after hydrophobic modification. The SEM photo of the coating suggests that the coating surface has a classⅡ micro-nano rough structure. The testing results of coating hydrophobic property indicate that the contact angle reaches 155.6°, and the coating has superhydrophobic ability. The various tests (adhesion, resistance against chemical reagents, salt spray resistance, impact resistance, et al) and site condensate water test of the coating confirm thatthe product has excellent performance resisting condensate water corrosion.
