Abstract
The present invention relates to the technical field of flexible drag reduction coatings, and in particular to a method for preparing a flexible and elastic drag reduction film. The flexible and elastic drag reduction film prepared by the present invention has excellent flexibility and elasticity. The film has a groove structure on a surface, and is suitable for curved surfaces and pipe surfaces of different diameters. The film is directly used without the need for an adhesive. It is sheathed on curved structures or devices of different diameters and curvatures by virtue of its own flexibility and elasticity, reducing an error due to the film adhesion.
