Description

technical field [0001] The invention belongs to the technical field of insulating materials, and in particular relates to an insulating coating for electrical equipment and a preparation method thereof. Background technique [0002] Insulating coatings are coatings with excellent electrical insulation properties and good electrical, thermal, mechanical and chemical properties. Insulating coatings are divided into two types: solvent-based and 600-1700°C water-based. The coating can form a layer of ceramic coating with high volume resistivity on the surface of the object to be coated, which can withstand a strong electric field without being broken down. The coating has high mechanical strength and good chemical stability, and is resistant to aging, water, and chemical corrosion; it also has mechanical shock and thermal shock resistance, and the coating can work continuously at the corresponding working temperature. [0003] The publication number is CN104341828A, which disc...
