Abstract
In order to apply to the one liquid type blocking adhesive, it was tried to microencapsulate the hardening agent for epoxy resin with epoxy resin by the interfacial hardening reaction method.In the experiment, the reaction time, the concentration of epoxy resin as the shell material and the impeller speed during the microencapsulation process were changed stepwise.It was investigated how these experimental conditions affect the structure, the gelation time and storage stability of microcapsules.It is found that the size, the content of hardening agent and the shell thickness of microcapsules could be controlled by changing the reaction time, the concentration of epoxy resin and the impeller speed.As a result, the storage stability and the gelation time of microcapsules were able to be changed widely.
