Modified nylon material and preparing method of modified nylon material

The invention discloses a modified nylon material and a preparing method of the modified nylon material. The modified nylon material comprises the following ingredients in percentage by weight: 45 percent to 55 percent of PA66, 10 percent to 15 percent of red phosphorus flame retardants, 22 percent to 30 percent of glass fiber, 5 percent to 8 percent of anti-freezing agents, 1 percent to 4.5 percent of mica powder and 0.5 percent to 1.5 percent of assisting agents. The preparing method of the modified nylon material comprises the following steps that: the PA66, the red phosphorus flame retardants, the mica powder and the assisting agents are weighed according to the weight ratio and are mixed; then, the mixture is added into a high-speed stirring pot to be stirred for 3 to 5 minutes at a high speed and is then added into a double-screw extruder; the glass fiber is added from an inlet of the extruder; the temperature is regulated to a specified value; and finally, discharging, water cooling, grain cutting and
