Novel Synthesis of Activated Carbon Spheres-Supported SnO2 for Reducing Smoke Release Volume and Fire Hazard in Flexible Poly(Vinyl Chloride)

摘要：

　　A novel catalyst combining activated carbon spheres (ACS) supported SnO2 (ACS@SnO2) was demonstrated to be more efficient than ACS or SnO2 alone to improve the thermal stability and flame retardancy of flexible poly(vinyl chloride) (fPVC).The resultant composite (ACS@SnO2) exhibits higher reactivity and excellent stability due to the well-dispersed SnO2 particles attached to ACS and the highly graphitized of ACS.Smoke suppression and the synergistic effect of ACS@SnO2 on fPVC were investigated by cone calorimeter test (CCT), and thermogravimetric analysis (TGA).The CCT data reveal that the addition of ACS@SnO2 notably improved the flame retardancy of fPVC, showing 32% and 58.4% decrease in peak heat release rate (pHRR) and in smoke production rate (SPR), respectively.The higher char yield which could retard the heat and mass transfer between gas and polymers.Furthermore, the ACS@SnO2/fPVC composite notably increased the amount of char residue, thereby decreasing the fire hazard of composites.
