| 摘 要： | 在厌氧胶中添加了N,N’-4,4’-二苯甲烷双马来酰亚胺（BDM）和苯乙炔苯酐封端的聚酰亚胺（PBDB-I）,测试了热强度、高温老化强度和热失重,考察了BDM和PBDB-I对厌氧胶的高温力学性能的影响,并借助FT-IR、DSC和SEM分析了耐高温树脂对厌氧胶耐热改性的机理。BDM与厌氧胶单体具有较好的热反应协同性,而PBDB-I与厌氧胶单体的热反应协同性较差,但将BDM与PBDB-I相结合作为耐热树脂可使耐热性大大提高,厌氧胶耐300℃老化的时间可超过60h。

| Abstract: | The hot strength, heat aging strength and TG of high-temperature resistant anaerobic adhesive containing BDM and PBDB-I were examined. The effect of BDM and PBDB-I on the high temperature mechanical property were investigated. FT-IR, DSC and SEM were used to analyze the modification mechanism. BDM had better thermal reaction synchronism with anaerobic adhesive monomer than that of PBDB-I. The combination of BDM and PBDB-I could greatly improve the high-temperature resistance of anaerobic adhesive. The aging time at 300℃ of the anaerobic adhesive could be more than 60h. |
