| 英文摘要 | The synergistic effect of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) immobilized silica (SiO2-DOPO) nanoparticles with an intumescent flame retardant (IFR) on the flame retardancy of polypropylene (PP) was investigated by UL 94 vertical tests and limiting oxygen index (LOI) measurements. It was found that the PP/IFR composites (25 wt%) achieved the UL94 V0 grade and LOI increased to 32.1 with an incorporation of 1.0 wt% SiO2-DOPO nanoparticles. Based on thermogravimetric analysis, scanning electronic microscopy and rheological analysis, it is speculated that three factors are mainly contributed to the improvement of the flame retardancy. First, the thermal stability of PP/IFR composites was improved by incorporating SiO2-DOPO nanoparticles. Second, the presence of SiO2-DOPO nanoparticles could induce the formation of a continuous char skin layer during combustion. The compact char layer could effectively impede the transport of bubbles and heat. Third, rheological analysis indicated that SiO2-DOPO nanoparticles could increase viscosity of the PP/IFR composites, which was also benefited to increase flame retardancy.
