摘要

The essence oil is difficult to microencapsulate and difficult to envelop into wall to prepare pressure sensitive microcapsules. The paper studied the preparation and micro-encapsulation of pressure sensitive perfume microcapsules with melamine formaldehyde resin (MF) and urea formaldehyde resin (UF) as double wall first time by using the in situ polymerization method, and the optimal preparation conditions were also studied. The double wall can enlarge the distortion of the passage of the essence oil leaving away, which prolongs the retaining time of essence oil from microcapsules applied to fragrance paper. The microcapsules were characterized on the structure, morphologies, thermal properties, mean particle size and size distribution. The experiment illustrated that the wall of microcapsule consisted of the MF resin, the UF resin had been synthesized in the process of preparation, the essence oil was encapsulated into the microcapsules, and the mean particle size and size distribution were well-proportioned and narrowed respectively. The particle morphologies were single core and global, and the wall was hermetically sealed. The results indicated that the influencing factors on the preparation of the microcapsules mainly were the temperature, pH value, and the reaction time.
