Kinetic study on pyrolysis of KFR-2 finishing fire retardant paints

The present article aims to introduce our analysis of TG and DSC curves of KFR-2 finishing fire retardant paints and ordinary Latex paints by using METTLER TA4000. It has also studied 25-TC15 thermal analytical apparatus and their pyrolysis courses. According to the DSC curve, it is possible to reduce the heat release of KFR-2 finishing fire retardant paints. TG and DTG curves show that the pyrolysis starting temperature is high while its ending temperature is low. As the decomposing distributing temperature is wide, the ratio of char can increase about 8% for KFR-2 finishing fire retardant paints. Based on the analysis of the thermodynamic model, we have obtained the thermodynamic parameter-activation energy of KFR-2 finishing fire retardant paints and its difference with ordinary Latex paints from the thermal analytical data. The results show that due to the addition of the retardants, the active energy of KFR-2 finishing fire retardant paints can obviously be enhanced. At the same time, its thermal stability and the heat-resistance can remarkably be improved.
