Environment-friendly photocuring insulating repair material and preparation method thereof

The invention discloses an environment-friendly light-cured insulating repair material and a preparation method thereof, and the light-cured insulating repair material comprises the following components in percentage by mass: 60-80% of light-cured resin, 1-5% of a photoinitiator, 10-30% of a reactive diluent and 1-26% of modified mica powder. The composite insulating material prepared by mixing the modified mica powder and the ultraviolet curing resin has good electrical performance, can ensure the safety and reliability of the generator before and after repairing the part, and meanwhile, by screening and compounding a plurality of reactive diluents, while the electrical performance is met, the service life of the generator is prolonged, and the service life of the generator is prolonged. The prepared repairing material is high in curing speed, not prone to cracking and small in pungent smell generation amount, overcomes the defects of an existing ultraviolet curing resin material, and is more environmentally
