NOVELTY - Flame retardant high temperature nylon-graphene composite material comprises 95-105 pts. wt. nylon salt, 2-10 pts. wt. graphene oxide, 3-8 pts. wt. organic nano-montmorillonite, 3-8 pts. wt. expanded graphite, 2-6 pts. wt. silane coupling agent KH560, 1-4 pts. wt. nanocarbon sols having 20-25% solids content, 2-4 pts. wt. nano titanium dioxide, 1-3 pts. wt. vermiculite powder, 0.5-2 pts. wt. strontium stearate, 0.2-1 pts. wt. capping agent, 0.1-0.6 pts. wt. 6-aminocaproic acid and 40-70 pts. wt. deionized water. USE - Used as flame retardant high temperature nylon-graphene composite material. ADVANTAGE - The material has excellent flame retardancy, high temperature resistance and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing flame retardant high temperature nylon-graphene composite material comprising (i) mixing nylon salt, graphene oxide, capping agent and 6-aminocaproic acid and ultrasonically dispersing at 50-85 degrees C for 1-3 hours to form premix which is then added into autoclave, (ii) adding nano carbon sol, organic nano montmorillonite, expanded graphite, silane coupling agent KH560, nano titanium dioxide, vermiculite powder and barium stearate with solid content of 20-25% into deionized water and ultrasonically stirring, then adding into high pressure reactor, and (iii) replacing air in the autoclave by nitrogen at least three times, then introducing nitrogen gas as reaction protective gas, heating at 160-260 degrees C until pressure reaches 2-3.5 MPa, maintaining pressure at 2-3.5 MPa by releasing water vapor in the reactor and constant pressure reaction time is 1-3 hours, releasing pressure in the reactor to normal pressure and discharging, where temperature in the kettle does not exceed 280 degrees C.
