Abstract

The invention discloses a superhydrophobic coating layer with an adjustable particle concentration, and a preparation method thereof. The superhydrophobic coating layer is composed of a component A and a component B according to a mass ratio of 75:1; the component A is composed of silicone resin, an organic solvent, silicon oxide, a dispersant, an antifoaming agent and a leveling agent, and the component B is a silicone resin curing agent. The preparation method comprises the following steps: (1) preparing a mixed solvent; (2) pre-dispersing particles; (3) dispersing a film forming matter; (4)preparing a superhydrophobic coating; (5) weighing a curing agent according to the mass ratio of the component A to the component B of 75:1, and performing stirring until uniformity; and (6) preparing the superhydrophobic coating layer. The superhydrophobic coating layer is constructed by using the unmodified particles, and the superhydrophobic effect of the coating layer can be realized within avery wide particle additive amount range without influencing the film-forming property of the coating layer.

Description

technical field [0001] The invention relates to a super-hydrophobic coating with adjustable particle concentration and a preparation method thereof, belonging to the technical field of super-hydrophobic coatings. Background technique [0002] A super-hydrophobic surface refers to a surface with a hydrophobic angle greater than 150° and a rolling angle less than 10°. In recent years, super-hydrophobic surfaces have attracted widespread attention due to their unique super-hydrophobic properties and self-cleaning properties, and have shown broad application prospects in both production and life. [0003] A large number of studies have shown that the construction methods of superhydrophobic surfaces are mainly divided into two categories: one is to construct micro-nano structures on the surface of low surface energy materials; the other is to reduce the surface energy of materials with micro-nano structures. [0004] Constructing micro-nanostructures on the surface of low surfa...
