Abstract

The invention provides high hydrophobic static-electricity conducting anti-icing coating and a method for producing the same, aiming at solving the problem existing in the prior art that the common low surface energy coating can not balance both hydrophilic characteristic and static-electricity conducting function. According to the technical scheme adopted to solve the problem, the high hydrophobic static-electricity conducting anti-icing coating comprises component A and component B, wherein the weight ratio of the component A to the component B is 9-16:1. The component A comprises the following materials by weight percent: 35-60 percent of the fluorocarbon resin, 10-40 percent of conductive powder, 1-8 percent of organic silicon compound, 0.5-3 percent of anti-aging agent, 0.5-5 percent of dispersant, 0.5-3 percent of anti-sedimentation agent and 10-40 percent of organic solvent. The component B is aliphatic and/or aromatic curing agent. After being coated on the surface of an electric wire, the high hydrophobic static-electricity conducting low surface energy anti-icing coating can delay the icing and reduce the adhesion force of the ice and the surface of the electric wire. In addition, with the static-electricity conducting performance, the high hydrophobic static-electricity conducting low surface energy anti-icing coating can protect the electric wire against lightning stroke.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a static-conductive anti-icing coating with high hydrophobicity and a preparation method thereof, which uses fluorocarbon resin as a film-forming material. Background technique [0002] Transmission lines are exposed in the natural environment, and their safe operation is closely related to the natural environment. For example, exposure to the sun and rain will cause the aging of the wires; the outer insulating surface of the power equipment will gradually accumulate dirt during operation; Great harm. [0003] my country's power grid construction is distributed in a wide range, spanning complex and diverse geographical terrains and climate environments, and is easily damaged by severe natural disasters such as ice and snow, lightning strikes, earthquakes, strong winds, and heavy rains. For example, in 2008, a large area of ​​freezing rain and icing occurred in the ...
