The invention discloses a composite coating for preventing the adhesion of freshwater shellfish. The sealing primer layer includes the following components: silane coupling agent modified epoxy resin, polyetheramine epoxy curing agent; the silicone anti-adhesion middle coating layer includes the following components: 107 silicone rubber, cross-linking agent, nano-filler, Thinner, catalyst; Fluorosilicone anti-adhesion surface coating includes the following components: hydroxyfluorosilicone oil modified silicone rubber, nano-filler, diluent, and catalyst. The composite coating of the invention can effectively reduce the breeding and adhesion of aquatic organisms and impurities such as freshwater shellfish on the inner walls of tunnels and pipes in water delivery projects. The present invention also provides a method for preparing the composite coating, which is simple, convenient and easy to operate. |
