Thermal Decomposition and Flame Retardance Behavior of Nanometer Magnesium Oxychloride Crystal Salt Involved in SMC
A detailed study of thermal decomposition behavior of nanometer magnesium oxychloride crystal salt involved in sheet molding compound has been carried out using differential scanning calorimetry, thermogravimetry and X-ray diffraction. The decomposing temperature changed from 112°C at the initial stage to 559°C at the end of the process. The results indicated that the thermal decomposition was carried out in the following three steps: releasing crystal water, then HCl secondly and finally structural water, the residua was magnesia. Nanometer magnesium oxychloride crystal salt addictives was used as flame retardance in sheet molding compound.
