Popis: Prediction of flammability characteristics of materials is possible via molar group contribution calculations. However, in most industries raw material composition is unknown and micro combustion calorimeter (MCC) is applied for measuring heat release rate (HRR) and calculates flammability characteristics. This work predicts HRR and flammability characteristics for complex formulations based on HRR from a reduced number of the individual constituents, all with unknown chemical composition. Water-based paints (> 15 components) with and without chemical interaction during thermal decomposition were predicted via linear combinations of component HRR and validated against experimental MCC data. Prediction of HRR and flammability characteristics was successful, and the obvious breakdown for reactive mixtures was confirmed. These results can be utilized as screening tool for flammability characteristics and identity component interaction in mixtures—which considerably enhances the strength of MCC in development of new materials.
