The graphene was decorated by carbon nanotubes(MWCNTs)and zinc hydroxystannate(ZHS),respectively.The hybrid nanoparticles were used as the core,the surfactant KH560 as the corona and polyether amine M2070 as the canopy.The solvent-free(GNS-MWCNTs)@M2070 and solvent-free(GNS-ZHS)@M2070 nanofluids were prepared,respectively.Then both of them with mass fraction is 2.0wt% were added into the epoxy resin(EP)to prepare(GNS-MWCNTs)@M2070/EP and(GNS-ZHS)@M2070/EP composites.The flame retardant property of the composites was characterized by the cone calorimeter test.The results show that the value of FIGRA index of pure EP,(GNS-MWCNTs)@M2070/EP and(GNS-ZHS)@M2070/EP are 3.682,3.118 and 4.391kW(m~2·s)~(-1),respectively.Compared with(GNS-MWCNTs)@M2070/EP,(GNS-ZHS)@M2070/EP has a lower smoke productiom rate(SPR),total smoke production(TSR)and carbon monoxide production(COP),which confirms that the ZHS deposited on the graphene sheet layers solvent-free nanofluid can better improve the flame retardant property of the epoxy resin.
