摘要

本研究乃利用尼龍6,6 ( Nylon 6,6)薄膜與丙烯腈-丁二烯橡膠(NBR)藉熱壓進行硫化反應製備積層複合材料，並探討其阻油性能。此外，利用光學顯微鏡(OM)、 掃瞄式電子顯微鏡(SEM)觀察其黏著界面的形態，並以滲透(permeability)、溶脹(swelling)、剝離(peel)、抗張潛變(tensile creeping)等試驗進行研究，探討NBR/尼龍、NBR/鋁合金和尼龍/鋁合金在不同界面時的接合劑配方、黏著強度、單一材料抗油特性及NBR、NBR/Nylon/NBR材料在潛變過程中的破壞時程。
結果發現NBR橡膠相對於Nylon膜有較大之溶脹程度，而Nylon 6,6阻油之特性較佳。此外，以NBR/Nylon/NBR積層複材、NBR橡膠、還有Nylon膜為容油容器的封口時，顯示NBR/Nylon/NBR積層複材與Nylon 膜為封口，有較佳的阻油效果(Nylon 6,6膜與NBR/Nylon/NBR積層複材隔片經過180天後皆仍具有良好之阻油性能)。而對0.75mm厚之NBR橡膠隔片而言，約於第45天左右隔片即已造成損裂。此外，以Chemlok 402 與Chemlok 233為接合黏著劑，NBR/Nylon接合之剝離強度可達120N以上(經T-type剝離試驗)。而吾人以PF+DER331為主原料之接合劑與PF+DER331+NBR為主原料之接合劑其剝離強度亦可達100N與80N以上。在NBR/鋁合金的接合上，則以Chemlok233/205接合，其接著強度可達200N以上(經180度剝離試驗)。最後在不同條件下吾人進行抗張潛變試驗，過程中記錄試驗材料的變化與斷裂時間，並在油中材料無缺陷之前提下，就目前有限之實驗資料及Tobolsky-Eyring模式進行評估，推測當NBR在應力106N/m2以下、NBR/Nylon/NBR複材在應力2×106N/m2以下，應皆可以長期使用。

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.
