▎ 摘　　要

NOVELTY - Graphene oxide/silicate stable dispersion system comprises 5-60 pts. wt. silicate oxide and 0.01-1 pts. wt. modified graphene oxide. The modified graphene oxide is prepared by dispersing graphene oxide in amino sugar. USE - Used as graphene oxide/silicate stable dispersion system. ADVANTAGE - The system: modifies graphene oxide by using amino sugar containing highly active amino functional groups; uses the amino functional group of the amino sugar for the graft reaction with the carboxy group and epoxy group on the surface of graphene oxide; achieves the grafting of amino sugar on the surface of graphene oxide; and improves the dispersion stability of the system, and dispersion performance of graphene oxide in water. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the graphene oxide/silicate stable dispersion system, comprising (i) dissolving the amino sugar in the solvent, and stirring to obtain an amino sugar solution, (ii) adding graphene oxide to the amino sugar solution, stirring and dispersing, and adding water to obtain a modified graphene oxide dispersion liquid, and (iii) adding a silicate solution dropwise to the modified graphene oxide dispersion liquid under stirring conditions, and adding water to disperse; and (2) a silicate paint comprising the graphene oxide/silicate stable dispersion system.
