【摘要】：以改性胺固化剂(1618)为囊芯、聚醚酰亚胺(PEI)为囊壁,采用溶剂蒸发法制备了EP(环氧树脂)固化用PEI包覆1618微胶囊。研究结果表明:固化剂芯材已被微胶囊PEI壁材成功包覆,其热稳定温度为130℃;以明胶作为分散剂时,制得的固化剂微胶囊表面光滑,分散性较好;随着芯壁比的增加,固化剂微胶囊的表面变得光滑、致密,并且其平均粒径减小(当芯壁比从1.0∶2.0增至1.5∶1.0时,平均粒径由45.8μm减至24.7μm)。
[Abstract]:Using modified amine curing agent (1618) as capsule core and polyetherimide (PEI) as capsule wall, 1618 microcapsules of EP (epoxy resin) cured by PEI were prepared by solvent evaporation method. The results show that the core material of curing agent has been successfully coated with microencapsulated PEI wall material, and its thermal stability is 130 鈩，
