With the development of economy and the progress of science and technology, the application of synthetic adhesives has been extended to all fields in the life. And it has become a very promising fine chemical industry. Epoxy resin adhesive has a series of excellent properties, making it popular in various industries. One-component epoxy component adhesives are also been focused on owing to its convenient use, long service life, environmental protection and low cost. In this study, we develop a one-component epoxy adhesives with microencapsulated amines by simply integrating a kind of amine microcapsules which were synthesized and investigated systematically in the epoxy matrix without external intervention.

With the development of economy and the progress of science and technology, the application of synthetic adhesives has been extended to all fields in the life. And it has become a very promising fine chemical industry. Epoxy resin adhesive has a series of excellent properties, making it popular in various industries. One-component epoxy component adhesives are also been focused on owing to its convenient use, long service life, environmental protection and low cost. In this study, we develop a one-component epoxy adhesives with microencapsulated amines by simply integrating a kind of amine microcapsules which were synthesized and investigated systematically in the epoxy matrix without external intervention. The morphology of amine microcapsules can be adjusted: spherical-fusiform-tubular. The obtained microcapsule possesses superior core fraction which was higher than reported work. And the prepared the one-component epoxy adhesives present excellent adhesion performance. With TEPA microcapsules which in possession of small particle size the one-part adhesives present comparable adhesion properties to the traditional two-part adhesives. This moderate and viable strategy provides a flesh route to encapsulate the hydrophilic amine and the preparation of one-component adhesives, which are charming, potential and of great importance in practical applications.
