Three kinds of flame retardant used herein were: 1 the artificial mesophase graphite powder MGP , 2 the sericite Al4 OH 4 KAlSi3O10 2 and 3 the graphite/sericite mixture. The sizes of MGP and sericite were sieved, and then the surfaces of MGP and sericite were modified using a Mechanofusion system. The MGP and sercite were characterized using a scanning electron microscope SEM , a particle size analyzer and an energy dispersive spectrum EDS . The IFRC, which consisted of 19.8 % of the flame retardant, 15 % of the dehydrate agent, 18 % of the foaming agent, 7.2 % of the resin binder and 40 % of the solvent, was prepared and daubed on the top of the plywood. The test of the fire protection of IFRC was conducted using a flammabilitytester. The IFRC with the flame retardant of the raw MGP or sericite was also prepared to realize the effects of the size distribution and the configuration of the flame retardant on the capability of fire protection of IFRC. The mass ratio of MGP to sericite also substantially affects the capability of fire protection of IFRC. Most interestingly, the capability o
