摘要

为研究高温环境对于2

6-三硝基间苯二酚铅（LeadTrinitroresorcinate

LTNR）热稳定性的影响，设计了71~100℃条件下的老化试验，采用形貌表征和热分解动力学分析相结合的方法研究LTNR在不同高温环境下的热稳定性变化。研究结果表明：高温环境下，LTNR的分子结构保持稳定，晶体缺陷显著增加，结晶性有所下降；其热稳定性呈现明显降低趋势，活化能

a从158.41kJ/mol降低至25.41 kJ/mol；试验后，LTNR的摩擦感度呈现敏感化趋势，摩擦感度值从16N降低至6N；高温环境下破坏LTNR晶体结构，导致其热稳定性降低。

Abstract

To investigate the influence of high-temperature environments on the thermal stability of leadTrinitroresorcinate(LTNR)

an aging testunder conditions ranging from 71℃to 100℃was conducted.Morphological characterization andthermaldecomposition kinetics analysiswasemployedto studyLTNR’sthermal stability evolution under different high-temperature conditions.The results show that

although the molecular structure of LTNR remains stable in high-temperature environments

crystal defects increase significantly and crystallinity decreases.The thermal stability of LTNR decreases markedly

withitsactivation energy

adroppingfrom 158.41 kJ/molto 25.41 kJ/mol.After high-temperatureexposure

the friction sensitivity of LTNR turns sensitive

with the value dropping from 16N to 6N.Overall

the thermal stability

reduction of LTNR in high-temperature environments is attributed to damage to its crystal structure.
