The present invention discloses a method for preparing a halogen-free low-smoke intrinsic flame-retardant nylon 66 composite material, which is implemented according to a conventional preparation process by taking an organic acid-modified metal hydroxide as a flame retardant. According to the present invention, an organic acid containing flame-retardant elements such as P, N and S is used for carrying out reactive modification on the metal hydroxide, so that the agglomeration behavior of the metal hydroxide in a polymer is effectively reduced, the compatibility between the flame retardant and nylon 66 is improved. 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.
