通过加入活性单体E,对自制苯并口恶嗪(FBZ)及FBZ/E的反应性进行了研究,并制作了FBZ层压板和FBZ/E层压板,研究了其力学性能、阻燃性及热稳定性。实验结果表明,加入活性单体E后,FBZ的凝胶时间缩短、活化能降低;FBZ/E层压板的弯曲强度和冲击强度都比FBZ层压板提高3倍多;FBZ层压板和FBZ/E层压板的氧指数都大于50,为难燃材料,且其热稳定性也有所提高。
The reactivity of home-made benzoxazine (FBZ) and FBZ / E was studied by adding reactive monomer E, and the properties of FBZ and FBZ / E laminates were also studied. The mechanical properties, Thermal stability. The experimental results show that the FBZ gel time is shortened and the activation energy is decreased after the addition of reactive monomer E. The flexural strength and impact strength of FBZ / E laminates are more than 3 times higher than that of FBZ laminates. FBZ laminates and FBZ / E Laminate oxygen index greater than 50, a flame retardant material, and its thermal stability has also been improved.
