Abstract

Montmorillonite as flame retardant was used to flexible poly (vinyl chloride) (PVC), and the flame retardant and smoke suppressant properties of PVC were investigated by the limiting oxygen index, smoke density rating, and cone calorimeter tests (CONE), the thermal degradation behaviors of PVC were studied by thermogravimetric analysis (TG) in nitrogen atmosphere. The mechanical properties testing resultant data show that montmorillonite better effect on the tensile strength of the sample. The CONE result indicated that montmorillonite can reduce the heat release rate in flame-retardant PVC: a more compact char residue formed on the surface of the sample with montmorillonite of the sample during the combustion process. The TG result showed that the sample with montmorillonite has higher thermal stability than pure PVC. Besides, PVC treated with montmorillonite and Sb2O3 showed a high limiting oxygen index, high decomposition temperature, which indicated that the flame retardance of the treated PVC was improved.
