Abstract

The invention discloses an anti-condensation coating and a preparation method thereof, and relates to the technical field of coatings. According to the anti-condensation coating provided by the invention, fluorosilicon resin is taken as a main body, and the fluorosilicon resin low-surface-energy coating has both organic silicon resin and organic fluororesin, so that the content of low-surface-energy components in the coating is increased, on the basis, other resin systems, cross-linking agents and auxiliaries are matched, so that the coating can be endowed with excellent weather resistance, hydrophobic property and the like, and therefore, the long-acting and lasting anti-condensation effect and excellent low surface energy performance are achieved. When the anti-condensation coating is sprayed on the surface of power distribution equipment, the surface performance of an insulating part and a cabinet body can be improved for a long time, condensation is prevented, and the construction, operation and maintenance cost of the anti-condensation device of the power distribution equipment can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-condensation coating and a preparation method thereof. Background technique [0002] In the power system, all kinds of switches, controls, terminal cabinets and other power equipment are the core of connecting to the power grid. Whether they can operate safely and stably affects the reliability of the power grid. When the power distribution equipment operates in an area with high relative humidity or large temperature difference, condensation is easily generated on the surface of the cabinet and the surface of the insulating parts, resulting in electrical accidents. The commonly used anti-condensation method is to suppress the generation of condensation by destroying the physical conditions of condensation formation, that is, to install various heating, ventilation, and dehumidification equipment to keep the environment in the power distribution equipment cabinet dry, wh...
