Effect of coupling agent modified intumescent flame retardant on the mechanical properties, thermal degradation behavior, and flame retardancy of wood-flour/polypropylene composites
In this study,the effect of silane coupling agent modified intumescent flame retardant(K-IFR)on the mechanical properties,thermal degradation behavior,and flame retardancy of wood-flour/polypropylene composites(WPCs)were investigated.The tests showed that the mechanical properties of the WPCs contained K-IFR were better than those of the WPCs contained the unmodified IFR,especially the impact strength,which increased by 24.7%.Thermogravimetric analysis showed that K-IFR could catalyze the WPCs to form more charred residue and endowed the WPCs with higher thermal stability.The incorporation of it increased the limiting oxygen index(LOI)by 23%and decreased the heat release rate by about 55%as compared with the WPCs without flame retardant.In addition,the results of LOI tests also demonstrated that K-IFR had better water resistance in the composite matrix than the unmodified one.
