Beschreibung
Zusammenfassung:	The invention belongs to the technical field of materials, and particularly relates to a self-healing microcapsule and a preparation method thereof, a self-healing basalt fiber and a preparation method thereof. The self-healing microcapsule comprises an epoxy resin capsule-core and a melamine-urea-formaldehyde copolymer wall layer, a curing agent layer and a melamine-urea-formaldehyde copolymer layer successively coated on the surface of the epoxy resin capsule-core. The self-healing microcapsule can be firmly loaded on the surface of basalt fiber, when the basalt fiber is damaged, the self-healing microcapsule with a double-layer structure can crack due to crack propagation, a repairing agent (epoxy resin) and a curing agent flowing from the self-healing microcapsule can polymerize to generate network macromolecules to repair cracks, and performance of the basalt fiber can be repaired. 本发明属于材料技术领域，特别涉及一种自修复微胶囊及其制备方法、自修复玄武岩纤维及其制备方法。本发明提供的自修复微胶囊包括环氧树脂囊芯和依次包覆在所述环氧树脂囊芯表面的三聚氰胺-尿素-甲醛共聚物囊壁层、固化剂层和三聚氰胺-尿素-甲醛共聚物层。本发明所
