芳香二胺的四缩水甘油醚树脂的湿热稳定性研究

Study on the Wet-hot Stability of Some TetraglycidylAromatic Diamine Resins

利用高效液相色谱、富里叶转换红外、差示量热扫描以及环氧值法研究了4,4'-二氨基二苯砜的四缩水甘油醚树脂(TGDDS)、4,4'-二氨基二苯醚的四缩水甘油醚树脂(TGDDE)和4,4'-二氨基二苯甲烷的四缩水甘油醚树脂(TGDDM)的湿热稳定性.实验结果表明水加速了化学变化,且其湿热稳定性为TGDDM^TGDDE>TGDDS.

:The wet-hot stability of N,N,N' ,N'-tetraglycidyl 4,4'diaminodiphenyl sulfon(TGDDS) N,N,N' ,N'-tetraglycidyl-4?'-diaminodtphenyl methane and N>N,N' ,N'-tetraglycidyl-4,4'-diamtnodiphenyl etherhas been investigated by using FT-IR, HPLC, DSC and the method of checking epoxide content- We foundthat water absorption by resins may significantly accelerata the hydrolytic rection.the wet-hot stability ofthree resins is TGDDS<TGDDE^TGDDM.
