【Abstract】 With isothermal and dynamic method,an analysis was made on the curing reaction of 250℃ high temperature strain gauge adhesive composed of unsaturated polyester 3301, styrene, cyclohexanone peroxide and cobalt(II)naphthqnate by using CDR-1 differential scaning calorimqter. Thermal effect and curing parameters were obtained in isothermal and dynamic conditions Apparent activity energy in isothermal and dynamic conditions were computed by using Arrhenius and Kissinger＇s equa-tions. The results obtained from this work provided very important infor-mation for determining processing coaditions of 250℃ high temperture stain gauae adhesive.更多还原
