摘　　要：以环氧大豆油与苯胺反应制备了环氧大豆油仲胺树脂,较优合成条件为0.3%三氟化硼乙醚催化、60~80℃反应24~48 h。控制苯胺/ESO反应投料物质的量比为2.5~3.0、实际反应物质的量比为2.0~2.5时得到的仲胺树脂具有较低的黏度及适当的反应活性,与HDI三聚体、TDI/TMP加成物、聚合MDI等种类固化剂配合使用,得到聚脲涂层具有优良的综合性能。Epoxy soybean oil secondary amine resin was prepared by reacting epoxy soybean oil with aniline.The optimal synthesis conditions are 0.3%catalyst of boron trifluoride ether,and 60~80℃for24~48h.Thesecondary amineresinobtained haslow viscosity and appropriate reaction activity when the aniline/ESO molar ratio of reaction feed is 2.5~3.0,and the actual reaction molar ratio is 2.0~2.5.The resin is used in combination with curing agents such as HDI trimer,TDI/TMP adduct,and polymeric MDI,to form a polyurea coating film which has excellent comprehensive performance.
