    摘要:

    为实现聚叠氮缩水甘油醚(GAP)的非异氰酸酯固化, 用多炔基化合物(TPTM)作GAP的固化剂, 通过傅里叶红外光谱(FT-IR)、力学性能和光学显微试验, 研究了TPTM体系和多异氰酸酯(N100)体系的反应活性和胶片性能。用差示扫描量热法(DSC)研究了TPTM体系的固化动力学。结果表明:在60 ℃下, TPTM与GAP可发生1, 3-偶极环加成反应形成三唑交联体系, 固化反应活性明显好于N100体系。TPTM含量变化对活化能影响较小, 对反应机理没有影响。得到的动力学方程能很好地预测实际应用时的固化历程。TPTM质量分数由3%增加到9.7%时, TPTM胶片拉伸强度由0.16 MPa增加到0.82 MPa, 断裂伸长率由149%降到17%。TPTM的质量分数为4%时, 达到N100固化体系在实际应用时(N100质量分数约10%)的力学性能, 且没有气孔。

    Abstract:

    To achieve the isocyanate-free curing of glycidyl azide polymer (GAP), the curing reactivity and properties of the films under multiple acetylene-terminated compound (TPTM) curing system and triisocyanate (N100) curing system were studied via FT-IR technology, test machine and optical microscope. The curing reaction kinetics of TPTM curing system was explored by differential scanning calorimetry. Results indicate that GAP and TPTM can happen 1, 3-dipolar cycloaddition reaction to form triazole cross linking system at 60 ℃, and the curing reactivity is much better than that of N100 curing system. The effect of TPTM content on activation energy is slight, but on the reaction mechanism is little.The kinetic equation obtained can well predict the curing process in actual application. With the mass fraction of TPTM increasing from 3% to 9.7%, the tensile strength of TPTM curing films increases from 0.16 MPa to 0.82 MPa, and the elongation at break decreases from 149% to 17%. When the mass fraction of TPTM is 4%, the TPTM curing films meet N100 curing system in actual application on the mechanical properties (the mass fraction of N100 is about 10%) and there is no air hole in the films.
