▎ 摘  要

NOVELTY - Flame-retardant high temperature-resistant nylon graphene composite 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, 1-4 pts. wt. nano-carbon sol containing 20-25% solid content, 1-4 pts. wt. nano titanium dioxide, 1-3 pts. wt. mica, 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 flame-retardant high-temperature nylon graphene composite material. ADVANTAGE - The composite material has mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite material, comprising (i) mixing nylon salt, graphene oxide, blocking agent and 6-aminocaproic acid, and ultrasonically dispersing for 1-3 hours at 50-85 degrees C to form a premix and adding the premix into a high-pressure reaction kettle, (ii) adding nano-carbon sol containing 20-25% solid content, organic nano montmorillonite, expandable graphite, silane coupling agent KH560, nano titanium dioxide and mica into deionized water, ultrasonically mixing, and adding to the reaction kettle, and (iii) replacing air by nitrogen in the reaction kettle for at least 3 times, introducing nitrogen as reaction gas, heating to 160-260 degrees C under pressure of 2-3.5 MPa, maintaining pressure at 2-3.5 MPa by releasing water vapor in the reactor, maintaining constant pressure reaction time for 1-3 hours, then releasing the pressure in the reaction kettle to atmospheric pressure, discharging, and maintaining the temperature in the kettle not greater than 280 degrees C during the reaction.
