Abstract

The invention discloses a method for preparing a superhydrophobic coating and a film with a hydrophobic migration property, and relates to the technical field of hydrophobic materials. A method of introducing silicone oil having a migration property into the superhydrophobic coating is adopted, and the superhydrophobic coating has hydrophobic migration characteristics under the conditions that a superhydrophobic function of the original superhydrophobic coating is not weakened. The superhydrophobic insulating film formed by coating and curing of the superhydrophobic coating with the hydrophobic migration property has a 167-degree static state hydrophobic angle with water, and a roll angle can be as low as 1.6 degrees; hydrophilic diatomaceous earth is adopted on the surface of the film forsmearing, the static contact angle between the surface of the diatomaceous earth and the water is 151.2 degrees in 72 h, and the roll angle is 7.2 degrees, showing excellent hydrophobic migration. The product has great application value in the fields of self-cleaning anti-pollution flashover, electric anti-condensation, anti-icing and the like of high-voltage insulators.

Description

technical field [0001] The invention relates to the technical field of hydrophobic materials, in particular to a method for preparing a superhydrophobic coating and a film with hydrophobic mobility. Background technique [0002] Superhydrophobic film refers to a film with a contact angle of more than 150 degrees to water droplets and a roll angle of less than 10 degrees. It has functions such as waterproof, self-cleaning, and anti-fouling, so it has broad application prospects in daily life and industrial fields. The bionic superhydrophobic surface utilizes the bionic superhydrophobic self-cleaning principle of lotus leaves and cicada wings, etc., by modifying low surface energy components on the surface with micro-nano rough structure or constructing roughness on the surface of low surface energy, to realize the self-cleaning of solid surface. Super hydrophobic function. Due to the superhydrophobic properties, the water droplets take away the dust particles and dirt adheri...
