Flame retardance and thermal degradation of CMC-Na fibers were investigated using limiting oxygen index (LOI), thermal gravimetry (TG), differential TG (DTG) and Scanning electron microscopy (SEM). The LOI values of different CMC-Na fibers are 23, 26, 28.5, 31 and 34, compared with about 20 for viscose fiber. TG and DTG studies indicate that the temperature of maximum degradation rate and the maximum degradation rate for CMC-Na fibers are much lower than those of viscose fiber. However, CMC-Na fibers generate much more residues or carbonaceous char than does viscose fiber. The increase of sodium ion content, the carbon residual also increases. SEM studies of combustion residues after LOI testing indicate that all CMC-Na fibers produce intumescent, hard and brittle residue crusts.

Hemp was treated with guanidine nitrate to impart flame retardance. The thermal degradation of the samples were studied by thermogravimetry (TG) and differential thermal analysis (DTA). The flame retardance was determined by LOI. Morphology of the char structure was studied by SEM to obtain information concerning the thermal degradation mechanism. For hemp treated with guanidine nitrate, which has higher LOI and char yield values, the oxidative decomposition stages include a decomposition stage at lower temperatures (203-240°C) , leading to more carbonaceous residue and small amount of flammable products to get the good flame retardance. The SEM of the chars of hemp treated with guanidine nitrate also indicate the structure of the charring layer may increase heat insulation, and protect inner matrix materials.

Degradation Behaviour

The effect of intumescent flame retardant (IFR) contained microencapsulated red phosphorus on the flame retardance of E-44 epoxy resin (EP) was studied. The test results indicated that good flame retardancy can be realized when epoxy resin treated with 30% IFR. Thermogravimetric analysis showed that the charring amount at high temperature of EP can increase substantially when IFR was incorporated. In order to further explain this phenomenon, Dolye integration method of thermal degradation dynamics was employed to study the thermal degradation process of EP treated with IFR based on the microencapsulated red phosphrous according to the thermal gravimetry analysis results.The activation energy and reactor order of different thermal degradation stages were obtained. The results of thermal degradation dynamics implied the intumescent flame retardants can improve the flame retardance of the epoxy resin through decrease the degradation speed and increase the activation energy of the second thermal degradation stage.
