Problems solved by technology

Although this measure can improve the performance of the RTV coating, it cannot eradicate the above-mentioned defects, and will cause other adverse effects
For example, with the increase of silica, the hydrophobic migration speed of the coating will decrease significantly

Abstract

The invention discloses room-temperature type power insulator anti-fouling flashover paint, a preparation method thereof and a power insulator. The paint comprises a hard paint and a room-temperature curing agent, wherein the hard paint comprises the following components: resin with hydrophobic migrating performance, silicone acrylic resin, a solvent and a leveling agent; and the room-temperature curing agent comprises the following components: a catalyst and ethyl orthosilicate. Compared with the prior art, the paint has excellent hardness, a self-cleaning property, hydrophobicity and curing performance.

Description

technical field [0001] The invention relates to coatings, in particular to a room temperature type power insulator anti-pollution flashover coating and a preparation method thereof, as well as a power insulator. Background technique [0002] Anti-pollution flashover room temperature vulcanized silicone rubber coating (RTV coating) has been widely used in the external insulation of power systems, which has prevented the occurrence of pollution flashover accidents to a certain extent. However, difficult defects are also exposed during use, which is manifested in the poor self-cleaning performance of the RTV coating. The surface of silicone rubber material has the characteristics of "oiliness", which is easier to absorb dirt than the surface of hard and smooth materials. After absorbing dirt, it is more difficult to clean the dirt on the surface of RTV under the action of natural wind and precipitation. Therefore, compared with the surface of glass and porcelain insulators, th...
