The thermal behavior of polyurethane adhesive in air atmosphere was investigated by thermogravimetry (TG) and derivative thermogravimetry (DTG). The kinetic parameters were evaluated by TG method and dynamic method, and the isoconversional method was employed to verify the values. The results showed that there were three main decomposition stages in the DTG curves. The apparent activation energy values determined using the TG method were 144.31-148.35 kJ·mol-1 for the first stage of decomposition, 196.96-204.26 kJ·mol-1 for the second stage and 202.97-205.27 kJ·mol -1 for the third stage. The non-isothermal degradation was found to be first order reaction, and the activation energy increased with the increase of mass loss. The lifetime estimate indicated the maximum lifetime of polyurethane under 35 ℃in air to be 10 years . The kinetic data suggested that polyurethane adhesive had excellent thermal stability.
