Abstract

In order to study the thermal safety of ANPyO and NBR moulding powder, the ANPyO was improved moldability with NBR by means of the solution-water suspending-distillation method and its thermal behavior was studied by Thermogravimetric-Differential Scanning Calorimeter (TG-DSC) thermal analyzer. The thermal decomposition activation energy and the pre-exponential factor were calculated by Kissinger method, Ozawa method and various integral methods. And the self-accelerating decomposition temperature, the thermal ignition temperature, and the critical temperature of thermal explosion of ANPyO / NBR were calculated. Then the time to ignition of spherical ANPyO / NBR samples with radius of 1m at different supercritical ambient temperatures was calculated. The results show that the moulding powder ANPyO / NBR has good heat resistance and thermal safety performance, and that the thermal safety of ANPyO / NBR is decided by the ambient temperature. © 2019 China Safety Science Journal
