Description
Technical Field
The invention relates to preparation of a super-hydrophobic coating with an anti-icing/deicing function, in particular to a super-hydrophobic coating compounded based on hydrophobic nano silicon dioxide and hydrophobic carbon nano tubes and a preparation method thereof.
Background
Icing of the transmission line may cause severe problems of short circuit due to overload of the line, frequent ice flashing due to ice coating of the insulator string, and line breakage due to uneven ice coating of adjacent blocks. Most of the conventional deicing methods are high-altitude manual deicing or power line heating to melt an ice layer. However, these methods are either dangerous or energy intensive, making it difficult to remove the ice layer safely and with low energy consumption. The super-hydrophobic coating has low surface energy, so that water drops are difficult to stay on the surface of the super-hydrophobic coating, and meanwhile, an air layer existing on the surface of the super-hydrophobic coating can play a role in delaying heat transfer. Therefore, the super-hydrophobic coating also has higher research value in the anti-icing field. The nano silicon dioxide has good ageing resistance and ultraviolet resistance and higher stability, and is widely applied to the fields of resin composite materials, coatings, sealants and the like. The carbon nano tube has many mechanical, electrical and chemical properties and has wide application prospect. And the tubular rod structure is easier to build up proper structure fluctuation, so that a micro-nano structure is formed, and the method can be applied to the field of super-hydrophobicity.
