| Abstract: | The rheology property and curing reaction process under different technological conditions of benzoxazine-MA resin system were studied by viscosity testings and dynamic DSC.The results showed that the time of the resin with viscosity lower than 500 mPa · s at 95-115 ℃ was up to 350 min and the gel temperature,curing temperature and the post treatment temperature of the resin systems were 185 ℃,213 ℃ and 248 ℃,respectively.The apparent activation energy was 87.5 kJ/mol according to Arrhenius formula.The curing technology and post treatment process was determined to be 130 ℃/3 h+140 ℃/1 h+150 ℃/1 h+160 ℃/1 h+170 ℃/1 h+180 ℃/2 h+210 ℃/2 h and 250 ℃/2 h,respectively. |
