With bisphenol A type epoxy resin (E - 5 1) for sac core， 酫 resin urea formaldehyde， urea - (UF) for bursa wall， using in situ polymerization synthesis microcapsule preparation different microcapsule content of polyester/microcapsule Through electronic tensile machine determination of the mechanical properties of materials， scanning electron microscope specimens cross-section Microcapsules on polyester material has toughening and repair Since repair mechanism is the crack front microcapsule， bursa wall under stress rupture， appear capsule core epoxy resin outflow and inflows cracks， the fracture surface glue， achieve self-repairing Since restorative materials design and engineering application， to extend materials at impact， loading and high temperature condition and improve the service life of construction safety has important
Abstract: Take the double phenol A epoxy resin (E -5 1) as the pouch core， the urea 酫 resin (urea-formaldehyde， UF) is the pouch wall， uses the home position polymerization law to synthesize the micro capsule， the preparation different micro capsule content polyester/micro capsule Through electronic pulling force machine determination material mechanical properties， scanning electronic microscope observation test sample cross section The micro capsule has the plasticizing and the repair function to the polyester From the repair mechanisms is the micro capsule front end the crack under the stress function， the pouch wall presents the breakage， the pouch core epoxy resin flows out and flows in the crack， binds the crack surface， achieves from the repair From the repair material's design and the project application， to lengthen the material in is under the impact， the load and the hot conditions service life and enhances the project to have important safely
： With polyphenol a type of epoxy resin (e -5 1 for every) core， 脲 酫 resin (urea - formaldehyde， uf) for every wall and the place got into a lawful capsule， the capsule with different levels of polyester a by the pull of the determination of the materials have to scan electron microscopic studies have this type of a capsule is polyester materials having 增韧 and repair since the restoration of mechanism is in a capsule the front-end stress， a breakup， a purse for epoxide resins comes out every lead and into the cracks in the sticks together to achieve since the restoration of since the restoration of the design and engineering applications for extension of material under the impact， loading and the conditions of life and improve the security
