Abstract

The invention discloses a method for preparing a fiber-reinforced epoxy resin-based composite material super-hydrophobic surface, which comprises the following steps of: firstly preparing fiber-reinforced materials, inorganic powder, an epoxy resin adhesive and a curing agent and then mixing the raw materials according to a certain mixing ratio to form an external coating resin system; additionally weighing the epoxy resin adhesive and the curing agent and mixing to form an intermediate layer resin system; coating the external coating resin system in a forming mold and laying a first layer of the fiber-reinforced materials; coating the intermediate layer resin system on the first layer of the fiber-reinforced materials and laying a second layer of the fiber-reinforced materials; repeatedly coating the intermediate layer resin system on the second layer of the fiber-reinforced materials and then doing in the same manner to obtain a preformed body of a composite material; and finally obtaining the fiber-reinforced epoxy resin-based composite material super-hydrophobic surface through curing, acid dipping, taking out and drying. The preparing method disclosed by the invention has the advantages of simple operating process, good controllability, good reproduction, low cost, environment protection and safety, excellent product quality and the like.

Description

technical field [0001] The invention relates to a preparation method of a superhydrophobic surface material, in particular to a preparation method of a superhydrophobic surface of an epoxy resin-based composite material. Background technique [0002] Fiber-reinforced epoxy resin-based composites have attracted extensive attention due to their designability, high specific strength, and light weight. They have very important applications in various fields such as wind turbine blades, large aircraft, ships, and automobiles. However, the surface of the current commercial fiber-reinforced epoxy resin-based composites is not self-cleaning, and it is easy to accumulate dust after long-term use outdoors, which affects the appearance. When sewage drops (or splashes) on the surface of fiber-reinforced epoxy resin-based composites When it is not wiped off in time, obvious pollution marks will often be left on the surface. In addition, many epoxy resin-based composite materials have cer...
