Montmorillonite modified epoxy resin slow-release self-repairing microcapsule and preparation method thereof
The invention provides a montmorillonite modified epoxy resin slow-release self-repairing microcapsule and a preparation method thereof, and belongs to the technical field of microcapsules. A solvent evaporation method is adopted, ethyl cellulose serves as a wall material, montmorillonite modified epoxy resin serves as a core material, the particle characteristics of the montmorillonite modified epoxy resin slow-release self-repairing microcapsule are controlled by changing the content of montmorillonite, and the release rate is adjusted. The montmorillonite-modified epoxy resin slow-release self-repairing microcapsule prepared by the invention is good in microstructure, narrow in particle size distribution, high in microcapsule yield and core material content, stable in chemical structure and relatively high in encapsulation efficiency. The montmorillonite modified epoxy resin slow-release self-repairing microcapsule can better regulate and control the slow-release performance, and can release the core material more stably for a long time.
本发明提供了一种蒙脱土改性环氧树脂缓释型自修复微胶囊及其制备方法，属于微胶囊技术领域。本发明采用溶剂蒸发法，以乙基纤维素为壁材，蒙脱土改性环氧树脂为芯材，通过改变蒙脱土含量来控制蒙脱土改性环氧树脂缓释型自修复微胶囊颗粒特征，调节释放速率。本发明制得的蒙脱土改性环氧树脂缓释型自修复微胶囊微观形貌良好，粒径分布窄，微胶囊产率和芯材含量高，化学结构稳定，包封率较高。本发明蒙脱土改性环氧树脂缓释型自修复微胶囊能够更好地调控缓释性能，能够更稳定且长期地释放芯材。
