Meanwhile, a series of flame-retardant functional groups such as P, N and S are introduced, so that the flame retardancy of the nylon 66 is greatly improved, the smoke suppression effect is achieved to a certain extent. Therefore, the prepared intrinsic nylon 66 composite material has desirable flame retardancy (an oxygen index can reach 25.8) and low smoke effect.
