| Abstract: | The thermal decomposition kinetics of the aluminum diethylphosphinate（DEPA） flame retardant was studied by TG-DTG techniques.The kinetic parameters,including the activation energy and frequency factor of the decomposition process for the compound were calculated through the Kissinger-AkahiraSunose（KAS） and Flynn-Wall-Ozawa（FWO） method and the thermal decomposition mechanism was also studied with the atava-estk method.The results show that the activation energy was 260.2 kJ / mol and with the KAS method and 259.4 kJ / molwith the FWO method respectively.The thermal decomposition mechanism belongs to phase boundary reaction and the kinetic equation of the novel flame retardant can be expressed as g（α） = 1-（1-α）^1 /3. |
