Abstract
The curing process and kinetics of tris (dimethylaminomethyl)phenol(DMP-30)/epoxy resin(E-51)/maleic anhydride(MA) systems were investigated by DSC using a non-isothermal method under different heating-up rates. The apparent activation energy of the curing system was calculated by Kissinger method and Ozawa method respectively, and the reaction was classified by Crane formula. Moreover, the optimized curing process was analyzed by DSC, and the curing behavior of the curing system with 2% (wt) DMP-30 was predicted. The results indicate that the apparent activation energy and reaction temperature of DMP-30/E-51/MA systems decrease with the increase of DMP-30, and the curing process of the curing reactions follows the first order reaction. The addition of DMP-30 does not change epoxy resin curing mechanism. DSC data shows that the optimized curing process of the curing systems is℃℃℃90/2h→120/2h→130/1h. The curing behavior of the curing system with 2% (wt) DMP-30 is predicted by curing kinetics equations, which provides theoretical basis to achieve higher curing degree by raising temperature and increasing reaction time.关键词
