NOVELTY - High temperature resistant nylon composite functional material comprises 95-105 pts. wt. nylon salt, 2-10 pts. wt. graphene oxide, 2-6 pts. wt. organic nano-montmorillonite, 3-8 pts. wt. expanded graphite, 2-6 pts. wt. silane coupling agent KH560 (3-glycidoxypropyltrimethoxysilane), 1-4 pts. wt. nano-carbon sol having solid content of 20-25%, 1-4 pts. wt. nano titanium dioxide, 1-3 pts. wt. nano zirconium silicate, 1-3 pts. wt. sepiolite powder, 0.2-1 pts. wt. blocking agent, 0.1-0.6 pts. wt. 6-aminocaproic acid and 40-70 pts. wt. deionized water. USE - Used as high temperature resistant nylon composite functional material. ADVANTAGE - The composite functional material: has excellent flame retardancy, abrasion resistance and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nylon composite functional material, comprising (i) mixing uniformly nylon salt, graphene oxide, blocking agent and 6-aminocaproic acid, and ultrasonic dispersing at 50-85 degrees C for 1-3 hours to obtain premix, and adding the premix into high pressure reaction kettle, (ii) adding nano-carbon sol having solid content of 20-25%, organic nano-montmorillonite, expandable graphite, silane coupling agent KH560 (3-glycidoxypropyltrimethoxysilane), nano titanium dioxide, nano zirconium silicate and sepiolite powder into deionized water, mixing under ultrasonic stirring condition, then adding into the reaction kettle, and (iii) replacing air in high pressure reaction kettle with nitrogen gas for at least three times, under nitrogen gas atmosphere, heating to 160-260 degrees C and pressurizing to 2-3.5 MPa, releasing water vapor in the reaction kettle at 2-3.5 MPa, carrying out pressure reaction for 1-3 hours, releasing pressure in the reactor to atmospheric pressure, then discharging, and reacting at not greater than 280 degrees C.
