Summary: | The invention relates to the technical field of dielectric functional materials, in particular to a dielectric dielectric coating, a preparation method thereof and a solid insulation component. The preparation method of the dielectric constant coating comprises the following steps: preparing a liquid composite coating containing a dielectric filler, a reactive diluent, a photocuring prepolymer and a photoinitiator; coating the surface of a base material with the liquid composite coating to obtain a liquid coating; and carrying out electro-optical excitation treatment on the liquid coating, and then carrying out light curing to obtain the dielectric gradient coating. According to the preparation method, electro-optical excitation is adopted for assisting photocuring, self-adaptive enrichment/orientation of the dielectric filler can be achieved through electric field force, and therefore the surface dielectric strength can be constructed, and the along-surface electric strength is improved. Therefore, the prepa |
