Abstract
To reveal the curing reaction characteristics of polyurethane-crosslinked energetic composite slurry,this study derived the curing kinetic equations for the HTPB/IPDI system based on the evolution of characteristic functional groups monitored by in-situ ATR-FTIR spectroscopy during the curing process.The evolution of characteristic groups was monitored at 45℃,50℃,55℃,60℃and 65℃.Using the derived equations,kinetic curves for the slurry curing reaction were constructed,and the ap-parent activation energy was determined.The results indicate a two-stage curing process.The first stage corresponds to the pre-gelation period,with an apparent activation energy(Ea1)of 69.83±5.54 kJ·mol-1.The second stage corresponds to the post-gelation curing period,with an apparent activation energy(Ea2)of 71.31±4.45 kJ·mol-1.The apparent activation energy for the HTPB/IPDI energetic composite slurry is significantly higher than that of a homogeneous HTPB/IPDI mixture.关键词
