Abstract A flame retardant composition was prepared by using phosphoguanidine, guanidine sulfamate, disodium octaborate
tetrahydrate and dodecyl dimethyl benzyl ammonium chloride. Veneers were immersed in such flame retardant mixture to prepare plywood. The combustion characteristics and thermal stability of plywood were assessed using a cone
calorimeter and TG. Results showed that: (1) High concentration and loading of flame retardant were beneficial for
the fire resistance of the plywood. (2) The limiting oxygen index (LOI) and residual mass of plywood processed using
the flame retardant was increased by 87.52% and 58.66% compared to those of the untreated… More >
