Abstract
This study employed an oil-in-water (O/M) emulsion to create microcapsules with urea-formaldehyde resincoated modified epoxy resin core material using a one-step in-situ polymerization approach. The drawback of utilizing n-butyl glycidyl ether (501) as a modified epoxy resin diluent. The impacts of several process factors on the size distribution, average diameter, and surface morphology of microcapsules were explored in this article, including heating rate, stirring rate, reactant ratio, and concentration. Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), optical microscope (OM), laser particle size analyzer, thermogravimetric analyzer (TG), and other techniques were used to investigate the chemical structure, surface morphology, and particle size of the microcapsules. The findings reveal that the microcapsules’ performance has substantially improved, providing a theoretical foundation for their widespread use.
