本发明公开了一种原位反应法制备环氧树脂改性的纤维素纳米颗粒及其应用,属于薄膜材料领域。该方法以E44环氧树脂和CNC为原料,反应生成CNP/E44;然后加入双酚A,制备获得CNP/EP;加入固化剂、刮膜,得到CNP/EPF。与现有的纳米纤维素/有机溶剂型环氧树脂复合材料相比,原位反应法制备的CNP‑g‑E44可以同时增强和增韧有机溶剂型环氧树脂薄膜,具有很好的实用性。
The present invention discloses an in-situ reaction method for preparing epoxy resin modified cellulose nanoparticles and its application, belonging to the field of thin film materials. This method uses E44 epoxy resin and CNC as raw materials to react to generate CNP/E44; Then add bisphenol A to prepare CNP/EP; Add curing agent and scraping film to obtain CNP/EPF. Compared with existing nanocellulose/organic solvent based epoxy resin composite materials, the CNP-g-E44 prepared by in-situ reaction method can simultaneously enhance and toughen organic solvent based epoxy resin films, which has good practicality.
