USE - Antistatic polyamide composite material. ADVANTAGE - The antistatic polyamide composite material has better thermal properties, mechanical properties and good antistatic property, greatly broadens the range of processing and use temperature of the manufactured products, satisfies the requirements for use of various environmental temperatures and people flexibly adjusts the nano-scale graphene content in the products according to the anti-static requirements in practical applications to meet the requirements of practical applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an antistatic polyamide composite material, which involves: (A) adding 20-80 pts. wt. aliphatic dibasic acid, 20-80 pts. wt. aliphatic diamine, 5-100 pts. wt. nano graphene aqueous solution, 0.1-0.4 pts. wt. blocking agent, 0.01-0.06 pts. wt. catalyst and 30-160 pts. wt. deionized water to the autoclave; (B) vacuuming high pressure reaction kettle to nitrogen, and then the pressure is adjusted to be higher than the normal pressure of 30-50 kPa; (C) heating the high pressure reaction kettle, heating to the first temperature, the pressure is increased to 0.1-0.2 MPa, and then the constant temperature reaction is carried out for 1-3 hours; (D) raising the temperature to the second temperature and increasing the pressure to 1-3 MPa while maintaining the pressure constant; (E) heating up at a rate of 0.2-1.8 degrees C/min for 1-3 hours to a third temperature, the pressure is 1-3 MPa; (F) raising temperature, the pressure in the autoclave is released to normal pressure, and the pressure relief time is 0.5-2 hours, while maintaining the temperature constant until no exhaust gas escapes; and (G) completing reaction, the autoclave is filled with nitrogen gas, the pressure is adjusted to 0.5-1.0 MPa, and finally the material is pressed out of the strand to pelletize to obtain the antistatic polyamide composite material.
