| Outline of Final Research Achievements |
The influence of ion exchange zeolites in thermosetting resins such as unsaturated polyester resin and amine type epoxy resin on degradation behavior and control effects in acidic and alkali environment were investigated. Degradation behaviors were conducted by weight change, flexural strength, infrared spectrum analysis, energy dispersive X-ray spectroscopy, and its rate was evaluated element penetration depth and corrosion depth. The degradation behavior of zeolite filled thermosetting resins were different, and its rate was affected by ion exchange ability in the chemical structure of zeolite. Particularly, the degradation rate of zeolite HS-320 filled thermosetting resins was superior to the neat resins degradation rate. Consequently, the influence of ion exchange filler like zeolite on corrosion mechanism of thermosetting resin was considered to be an interesting result for discusses the degradation resistance of the materials and also for the life prediction.
