Description

Technical field [0001] The invention belongs to the technical field of unsaturated polyester resins, and particularly relates to an unsaturated polyester resin with excellent insulating properties and a preparation method thereof. Background technique [0002] Unsaturated polyester resins are generally linear polymer compounds with ester bonds and unsaturated double bonds formed by condensation polymerization of unsaturated dibasic acid diols or saturated dibasic acid unsaturated diols. Usually the expected acid value is reached. After the polyesterification reaction is completed, a certain amount of vinyl monomer is added while it is hot to prepare a viscous liquid. Such a polymer solution is called an unsaturated polyester resin. [0003] The insulating properties of the unsaturated polyester resins in the prior art cannot meet the requirements in actual use. Therefore, it is urgent to design an unsaturated polyester resin with excellent insulating properties to solve the problem...
