摘要为利用炔基化合物实现聚叠氮缩水甘油醚（GAP）的非异氰酸酯固化，解决传统异氰酸酯固化剂对水十分敏感，环境不友好，与二硝酰胺铵（ADN）相容性差、稳定性差等问题。选择和制备了两种多炔基化合物——均苯三甲酸三炔丙酯（TPTM）和均苯三甲酸三炔丁酯（TBTM），采用傅里叶红外光谱法(FT-IR)和差示扫描量热法(DSC)对其结构和性能进行了表征。通过傅里叶红外光谱法跟综了多炔基化合物与GAP的固化反应历程并与N100固化体系作对比，利用非等温差示扫描量热法研究了其反应动力学，获得了相关动力学参数，比较了相关固化剂的固化活性。选取活性较好的TPTM、N100制作了不同固化剂比例的固化胶片，通过拉伸试验研究了胶片的力学性能。结果表明：合成的TBTM和TPTM均能够固化GAP，但TBTM的反应活性较差。在60℃下TPTM可以在一天内与GAP反应完全，而TBTM体系6天也不能完全反应。TPTM、TBTM体系的固化反应活化能分别为80.3、87.7kJ/mol。固化胶片显微镜观察、拉力机作拉伸试验以及DSC胶片分解放热试验表明，TPTM胶片的各方性能要优于N100胶片。28889

Title GAP energetic adhesive curing agent and its curing process research
Abstract
For the use of acetylene compound realize glycidyl azide polymer (GAP) is a non-isocyanate curing, so as to solve the conventional isocyanate hardener very sensitive to water, environmentally unfriendly, and ammonium dinitramide (ADN) poor compatibility, poor stability issues. So choose prepared two more acetylene compound trimesic three propargyl (TPTM) and trimesic three alkyne ester (TBTM), using Fourier transform infrared spectroscopy (FT-IR) and differential scanning Calorimetry (DSC) structure and properties were characterized. By Fourier transform infrared spectroscopy (FT-IR) curing reaction mechanism with comprehensive multi-alkynyl compounds with GAP and the N100 curing system for comparison, reaction kinetics was studied using non-isothermal differential scanning calorimetry, get the relevant kinetic parameters associated with the activity compared curing curing agent. Select good activity TPTM, N100 produced different proportions of cured film hardener, test the mechanical properties of the film by stretching. The results showed that: synthetic TBTM and TPTM are capable of curing GAP, and reactivity TBTM poor. At 60 ℃ TPTM can react with GAP complete, but six days TBTM system can not completely respond within a day. TPTM, the curing reaction TBTM activation energy were 80.3,87.7kJ / mol-1. Cured film microscope, Rally for the tensile test and DSC film exothermic decomposition tests show that the parties to the performance of the film is better than N100 TPTM film.
