【摘要】：以改性胺固化劑(1618)為囊芯、聚醚酰亞胺(PEI)為囊壁,采用溶劑蒸發(fā)法制備了EP(環(huán)氧樹脂)固化用PEI包覆1618微膠囊。研究結(jié)果表明:固化劑芯材已被微膠囊PEI壁材成功包覆,其熱穩(wěn)定溫度為130℃;以明膠作為分散劑時,制得的固化劑微膠囊表面光滑,分散性較好;隨著芯壁比的增加,固化劑微膠囊的表面變得光滑、致密,并且其平均粒徑減小(當(dāng)芯壁比從1.0∶2.0增至1.5∶1.0時,平均粒徑由45.8μm減至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，
