碩士 === 國立臺北科技大學 === 化學工程所 === 93 === The first part of this study , Nylon6/6 film and the laminate of sheet nitrile rubber (NBR) were laminated by a hot press ,which investigated oil resistance .In this study, optical microscope(OM) and scanning electron microscope(SEM) are used to observe the adhesive joints. At the same time, this study by way of permeability, peel swelling, tensile, and tensile creeping test as test program. The second part of this study discussed the different adhesive formulas, peel strength, the anti-oil characteristic, and the aging process of composite materials. The result showed the NBR rubber had better swelling than the Nylon film. But, Nylon 6,6 had better anti-oils characteristics than NBR. In addition, comparing to NBR/ Nylon/NBR laminate composite, NBR rubber, and the Nylon film, it had been found that NBR/Nylon/NBR laminate composite and the Nylon film had the better resistance when blocked on the top of aluminum bottle, which filled with the JP-10. On the other hand, the NBR rubber (0.75mm is thick) was found leaking approximately 45 days. Besides, in the adhesive part, the NBR/Nylon laminate composite applied Chemlok 402 and Chemlok 233 as the adhesive. When using the T-type peel test to analysis the strength of its adhesive joints, the result was found that the strength able reach above 120N. And then mixing PF+DER331 and PF+DER331+NBR as the major adhesive components, the strength was able to reach above 100N and 80N.Moreover, when using 180-degree peel test to test the joint strength of NBR/ aluminum alloy material adhered by Chemlok233/205, the strength was able to reach above 200N. Finally, under different conditions, this study to analyze the relation between the tensile creeping and ageing. With limited test data and Tobolsky-Eyring model, the limitation of applying laminate composite was predicted. When NBR stress is below 2x 106N/ m2, and the NBR/ Nylon / NBR stress is below 2x 106N / m2, they should be allowed the long-term use in oil.
