摘要
Abstract
The EP/MNA/8280N75 epoxy resin system was made through adding benzoxazine into the EP/MNA system. The effect of benzoxazine on thermal property of EP/MNA system and its mechanism were researched. According to Thermo-gravimetric analysis ( TGA) and differential scanning calorimeter ( DSC) ,when adding benzoxazine at 40% of epoxy resin, the decomposition temperature increased to about 310 ℃ and the residue increased to 19. 8% with the curing temperature increasing a little. Fourier Transform Infrared Spectroscopy ( FT-IR) indicated the reaction mechanism which formed cross-linked structure with a high density. It could be attained because of the benzene rings in benzxazine molecule and the C—O—C rings opening reaction with epoxy. The results show that benzoxazine improves the thermal stability under a high temperature.关键词
