Technical field
The present invention relates to a kind of biomimetic material technology field, particularly relate to a kind of selfreparing macromolecular material.
Background technology
Macromolecular material inevitably produces local damage and tiny crack in its forming process and use procedure, and then cause macroscopic fracture and destroy, affect normal use and the reduction of service life of related products, and often these micro-damages are being difficult to find at first, even if or be found also because the restrictions such as shape of product cannot be repaired in time.Therefore, if macromolecular material self-repair function can be given, can solve the problem, significantly improve the security of product, extend its work-ing life.
Summary of the invention
Goal of the invention: the present invention is in order to repair the micro-damage problem of macromolecular material inside.
Technical scheme: the invention provides a kind of selfreparing macromolecular material, the repairing capsule comprising modified epoxy and be mixed in described epoxy resin and catalysis capsule, described repairing capsule and described catalysis capsule comprise capsule wall, described capsule wall consists of the following composition, 100-120 part epoxy resin-tetrahydrophthalic acid glycidyl ester, 60-100 part Epocryl.
Preferably, described repairing capsule inside comprises renovation agent, and described repair machine agent comprises: 60-80 part epoxy resin, 30-40 part polythiol-tetramethylolmethane four mercaptopropionic acid ester, 20-35 part sulfonated polyether-ether-ketone, 12-19 part PAH, 5-8 part water, 30-45 part perfluoro capryl Trimethoxy silane.
Preferably, be provided with catalyzer in described catalysis capsule, described catalyzer is benzyldimethylamine.
Preferably, described catalyzer can also be imidazoles renovation agent and dibrominated cylinder mixture the former have particulate state, profile is irregular and can produce focal point of stress, ensures to repair temperature at 120-140, has played renovation agent high temperature fixed line advantage.
Beneficial effect: compared with prior art, its advantage is to find the infringement in macromolecular material early, repairs infringement early in the present invention, capsule wall state of cure of the present invention and damaged degree moderate, repair rate is up to 90%.
Embodiment
Below in conjunction with embodiment, illustrate the present invention further.
