摘要
以乙二胺(EDA)、己二胺(HDA)、二乙烯三胺(DETA)和异佛尔酮二胺(IPDA)等四种脂肪族多胺室温固化剂对丙烯酸改性环氧树脂(AC-E44)进行了固化研究。实验研究表明:在相同的固化条件下,四种固化产物的综合性能都是随着固化剂用量增大而先增加后降低的,即存在着最佳固化量:EDA为8%,HDA为14%,DETA为10%,IPDA为22%。采用DSC技术研究固化产物的热稳定性。
The modified acrylic epoxy resin was cured by ethylenediamine （ EDA）, hexanediamine （ HDA）, diethyle-netriamine （DETA） and isophorone diamine （IPDA） as curing agent at room temperature. The experimental results indicated that the comprehensive properties of the four curing products first increased and then decreased varing with the amount of curing agent increasing. The optimal contents are EDA 8%, HDA 14%, DETA 10% and IPDA 22%, respectively. The thermostabilities of cured products were characterized by DSC.
