AI Technical Summary
Existing epoxy resin materials have poor durability in humid and hot environments, leading to aging of composite insulators and affecting the reliability of power systems. Traditional vulcanized silicone rubber and epoxy resin coatings have problems with poor mechanical strength and inadequate protective effects.
The plasma surface modification method is adopted. By coating the epoxy resin surface with dimethyl silicone oil and performing plasma treatment, combined with raw materials such as biphenyl epoxy resin and 4,4'-diaminodiphenyl sulfone, the resin's resistance to damp heat and hydrophobicity are enhanced.
It significantly improves the moisture and heat resistance and hydrophobicity of epoxy resin, reduces the entry of water molecules into the resin, extends the service life of the material, and enhances the stability of composite insulators.
