Abstract

The invention discloses a method for preparing an epoxy resin super-hydrophobic coat, comprising the following steps: (1), preparing collosol of the coat: dissolving silicon dioxide particles in a solvent, adding a silane coupling agent, heating and stirring for reaction, adding an epoxy resin paint and a hydrophobing agent, stirring for reaction, and obtaining the collosol of the coating layer; (2) coating film on the surface of a substrate material: coating the collosol obtained in the step (1) on the surface of the substrate through the way of lifting-pulling coating film, rotationally coating, curtain coating or spraying, after lifting, placing statically at the room temperature for using; and (3) heating and curing: putting the substrate material coated by the film in the step (2) in an oven, raising temperature to heat to make the epoxy resin cure and cross, taking out to obtain the epoxy resin super-hydrophobic coat. The invention has the advantages of easy technique, easily obtained raw materials, low cost and good repeatability; and the obtained coat has good super-hydrophobicity and self-cleaning performance for the industrial production of the super-hydrophobic paint properly.

Description

technical field

[0001] The invention relates to a method for preparing a hydrophobic coating, in particular to a method for preparing an epoxy resin super-hydrophobic coating by a surface graft modification method and organic / inorganic composite. Background technique

[0002] Surface properties are one of the most important physical and chemical properties of solid materials, and many physical and chemical processes, such as adsorption, catalysis, adhesion, friction, etc., are closely related to the surface properties of substances. The wettability is a main aspect of the surface properties of materials, and plays an important role in the fields of catalysis, coating, waterproofing, and biomedical materials. In recent years, superhydrophobic surfaces have attracted widespread attention. The hydrophobic properties of surfaces are usually described by the static contact angle and dynamic rolling angle of the surface with water. The so-called superhydrophobic surface refers to ...
