▎ 摘　　要

NOVELTY - High temperature resistant flame retardant graphene coating comprises urea-formaldehyde resin, 10-20 wt.% melamine resin and 5.5-8.5 wt.% graphene. The graphene includes a multiple stacked graphene monolithic layer structures. The monolithic layer structure includes a conjugated region and an edge region. The conjugated region is grafted with octadecylamine. The graft ratio of the octadecylamine is 3-5%. USE - High temperature resistant flame retardant graphene coating. ADVANTAGE - The high temperature resistant flame retardant graphene coating has improved high-temperature resistance and flame retardance graphene coating by uniform dispersion of the graphene in the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high temperature resistant flame retardant graphite coating, which involves: (a) mixing, dispersing graphene oxide and octadecylamine in a mass ratio of 1:1-1: (b)heating, stirring reaction, controlling the reaction temperature to be 85-95℃, the stirring speed is 300-800 revolutions per minute, and the reaction time is 80-120 minutes; (c) regulating, controlling the molecular structure of graphene oxide in order, where the graft ratio of octadecylamine is 3-5% to obtain graphene; (d) stirring, mixing uniformly urea-formaldehyde resin and the 10-20 wt.% melamine resin to obtain a compound resin; (e) dividing the graphene of 5.5-8.5% of urea-formaldehyde resin into three equal portion, marking as group first, second group and third group respectively; (f) adding first group to the compound resin, stirring, dispersing uniformly; (g)adding second group, stirring continuously, dispersing uniformly; (h)adding third group, stirring continuously, dispersing uniformly, and discharging the material to obtain the product, that is high temperature resistant flame retardant graphite.
