Low viscosity and high temperature resistance, environmental corona insulating paint and preparation method

The present invention relates to a low viscosity, high temperature resistance, environmental corona insulating paint and its preparation method, the insulating lacquer comprising: vinylphenyl silicon nano-silica hybrid was 100 parts; 5 to 50 parts of an organic resin; tetra isopropyl ester 0.5 to 1.5 parts; 1 ~ 5 parts of vinyl initiator; and 0.1 to 2 parts accelerator; 0.01 to 0.1 parts storage stabilizer. The resulting product of the present invention, the nanoparticles are small size, good distribution of the resin, no agglomeration, does not settle, the resulting product viscosity controllable, insulating paint of the present invention is environmentally friendly, low temperature curing, high temperature levels, corona resistant resistance, excellent dielectric loss, good storage stability, high mechanical strength, excellent in overall performance, fast drying and low viscosity advantages of simple preparation process various insulating paint, low raw material cost, suitable for large-scale production.
