摘要：

Nano-Sb2O3/mica flame retardant composition is synthesized by colloidal and assembling techniques. The morphology and assembled behavior of nano-Sb2O3 on mica are analyzed by means of X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The flame retardant properties and mechanism of nano-Sb2O3 and nano-Sb2O3/milica composition are studied by combustion test, thermogravimetric (TG) analysis, and differential scanning calorimetry (DSC). The results show that the nano-Sb2O3 particles assembling in nano-Sb2O3/mica composition distribute on the mica surface with smaller size (about 5 nm), higher dispersivity, narrower size distribution and alike shapes, compared with nano-Sb2O3 prepared by the normal method. The nano-Sb2O3/mica composition has achieved the same synergistic effects with chlorinated paraffin as nano-Sb2O3, and its flame retardant properties have been improved prominently through decreasing the temperature and combustion reaction rate of the polymer effectively and forming char. When the FRP sample contains about 7 wt% nanocomposition (i.e., containing about 0.8 wt% mica), it is self-extinguished once departing from the fire while combusting.
