Research on the Fire Resistance of BMI/DDM Resin Toughened by CTBN

摘要

Many factors that affect the flame resistance of the modified BMI system were studied, including the effect of different content of P_4, C_24H_29Cl_21/ZnO_3B_2o_3·5H_2O and C_24H_29Cl_21/MoO_3 on Oxygen Index of the modified Bismaleimide resin. The thermal stability and mechanical properties of the cured BMI resin were also measured. It showed that this new kind of modified bismaleimide resin had nice fire resistance, excellent thermal stability and mechanical properties.
