The invention discloses a nylon 66 material and a preparation method thereof, and belongs to the technical field of high polymer materials. The nylon 66 material comprises the following components in percentage by weight: 27%-86.7% of PA66, 0.1%-1% of a first flash inhibitor, 3%-10% of a second flash inhibitor, 10%-60% of glass fibers, 0.1%-1% of an antioxidant and 0.1%-1% of a lubricant, and the second flash inhibitor is aromatic polyamide. Aromatic polyamide is used as the second flash inhibitor and can be mutually entangled with PA66 molecular chains by utilizing the characteristics that molecules of the aromatic polyamide have rigid benzene rings, the crystallization temperature is relatively high, and the compatibility with PA66 is good, so that the aromatic polyamide can flow well, can be quickly formed, and greatly inhibits the generation of flashes. Meanwhile, the first flash inhibitor and the second flash inhibitor can generate a synergistic effect to further reduce the generation of flashes.
