▎ 摘  要

NOVELTY - High temperature-resistant wear-resistant nylon 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 (solid content of 20-25%), 1-4 pts. wt. nano-titanium dioxide, 1-3 pts. wt. talc, 1-3 pts. wt. sepiolite powder, 1-2 pts. wt. vermiculite 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 wear-resistant nylon composite material. ADVANTAGE - The nylon composite material has high-temperature resistance, wear resistance, good flame retardance and abrasion resistance with good mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the nylon composite material, comprising: (i) mixing the nylon salt, graphene oxide, blocking agent and 6-aminocaproic acid, ultrasonically dispersing at 50-85 degrees C for 1-3 hours to obtain a premix, then adding the premix into a high pressure reactor; (ii) adding nano-carbon sol, organic nano-montmorillonite, expanded graphite, silane coupling agent KH560, nano-titanium dioxide, talc, sepiolite powder and vermiculite powder into deionized water and mixing ultrasonically, then adding into a high pressure reactor; and (iii) replacing air in the reactor by nitrogen for at least three times, where the nitrogen gas is used as a reaction protective gas, reacting at 160-260 degrees C with a pressure of 2-3.5 MPa for 1-3 hours by releasing water vapor in the reactor, rleasing the pressure in the reactor to atmospheric pressure, maintaining a temperature of not greater than 280 degrees C in the reactor during the reaction and then discharging.
