Problems solved by technology

However, there is a lack of practical testing and theoretical support for recoating RTV coatings. During the use of RTV coating cleaning agents, many problems should be paid attention to: such as the type, composition and amount of pollutants attached to the surface of RTV coatings, and the aging residue of RTV coatings. Chemical composition, equipment, time and cost of cleaning operations, safety of cleaning operations, cleanliness after cleaning, environmental protection during cleaning, etc.
This limits the popularization and use of RTV paint cleaning agent to a certain extent
[0004] At present, it is also reported that the bionic lotus leaf effect is used to prepare superhydrophobic anti-fouling flashover coatings, such as Chinese Patent No. CN102417773, Chinese Patent No. CN102660182, Chinese Patent No. CN103666173 and Chinese Patent No. CN103642378 disclose four kinds of low Surface energy binder, a hydrophobic coating composed of hydrophobic nanoparticles as fillers, in certain occasions, it can have a good super-hydrophobic effect, but its wear resistance and adhesion are poor, and it will be damaged after a short period of wind erosion or friction Loss of super-hydrophobic properties, poor adhesion to plastic, glass and other substrates, limited use

Description

Technical field [0001] The invention belongs to the technical field of insulation protection, and specifically relates to a dirt-removing and self-cleaning insulator protection agent and a preparation method thereof. Background technique [0002] In severe weather conditions (such as rain, fog, dew, etc.), flashover will occur along the contaminated and humid insulator surface, causing a pollution flashover accident in the power system. In the power system, due to the wide range of power grid pollution flashover accidents and long power outages, they seriously threaten the safe operation of power transmission and transformation equipment and cause huge economic losses to the national economy. Therefore, the pollution flashover problem of the power grid has always plagued power An important subject of business development, how to effectively solve the problem of power grid pollution flashover has become an important task to ensure the safe production of power systems. [0003] In r...
