摘　　要：以腰果酚、甲醛和三乙烯四胺(TETA)为原料,通过曼尼希(Mannich)反应制备了腰果酚醛胺环氧固化剂(PCT);然后采用该固化剂制备出适合低温及潮湿基面粘接的新型环氧树脂(EP)灌浆料。研究结果表明:该EP灌浆料具有在潮湿基面上的可操作时间长(初凝时间为95 min)、拉伸剪切强度(最高为8.16 MPa)和湿态粘接强度(最高为3.18 MPa)高等优点;当m(EP)∶m(PCT)∶m(BGE)=100∶40∶20时,EP灌浆料的综合性能良好,完全符合JC/T 1041—2007标准要求。With cardanol,formaldehyde and triethylene tetramine（TETA）as raw materials,a cashew phenolic aldehyde amine epoxy curing agent（PCT）was prepared by Mannich reaction. Then,a new EP（epoxy resin）grouting material,which was used for bonding at low temperature and wet base surface,was prepared by the curing agent. The research results showed that the EP grouting material had some advantages such as the longer operable time（initial gel time at 95 min）on wet base surface,higher tensile shear strength（maximum at 8.16 MPa）and wet-bondingstrength（maximum at 3.18 MPa）. The EP grouting material had the good combination property,and could completely meet standard request of JC/T 1041—2007 when mass ratio of m（EP）∶m（PCT）∶m（diluent）was 100∶40∶20.
