Study on the HEA-Blocking Unsaturated Polyester Solventless Impregnating Varnish

Abstract:

An unsaturated polyester is synthesized by EG, BDO, PA, MA and other materials, and it is blocked by HEA lastly. After the resin is synthesized completely, adding additives of reactive diluent and initiator, etc, prepare the HEA-blocking unsaturated polyesters solventless impregnating varnish. The impact of technology on varnish is analyzed in the paper. The characterization of FTIR, TG, DSC and the testing result of main properties show the temperature of curing reaction is 125°C and 165°C; the temperature index of the impregnating varnish after curing is 182°C,.The volatile value of the varnish is 4.6%; The impregnating varnish has excellent electrical insulation properties, storage stability should be better.
