摘要: 
本研究以丁腈橡膠(NBR)為主體,添加Cloisite 30B、Cloisite 15A蒙脫土,C30B處理劑為methyl tallow bis(2-hydroxyethyl) quaternary ammonium(MT2EtOH),C15A處理劑為dimethyl dihydrogenatedtallow quaternary ammonIum(2MT2HT),藉由奈米等級蒙脫土提昇其物理特性,區分為三系統進行討論,分別為:NBR/蒙脫土系統、NBR/碳黑/蒙脫土系統、NBR/碳黑/PEG分散劑/蒙脫土系統。實驗的方式為利用高剪切力混練進行掺合製作NBR/奈米蒙脫土複合材料,再以XRD分析、橡膠流變機、木尼粘度計、萬能試驗機等進行物性試驗。
在NBR/蒙脫土系統中經過拉伸試驗,可看到控制組加入C30B 1 phr,其抗拉強度降幅近45 %,而延伸率降幅19 %,以雙滾輪進行分散作業時亦發現C30B微粒的凝集現象,使得奈米蒙脫土帶有兩個-OH基,形成氫鍵而凝集是造成物性大幅下降的主要原因。同一系統中,配方NBR/C15A1中為控制組加入C15A 1 phr後抗拉強度大幅提昇39 %,而延伸率小幅上升8 %;在NBR/碳黑/蒙脫土系統中控制組磨耗損失體積為162 mm3加入C30B 1 phr後磨耗損失體積提高為166 mm3,加入C15A 1 phr後磨耗損失體積下降為106 mm3,降幅為35 %,由以上兩系統單一物性數據差異,瞭解NBR添加1 phr蒙脫土可以影響物性19 ~ 45 %,而蒙脫土的改質劑所付予的官能基是關鍵。由XRD分析出現數個繞射峰,形成插層結構。
在NBR/碳黑/PEG分散劑/蒙脫土系統中,以PA(PEG400)/C30B為例,NBR添加C30B 1、3、5 phr的ts2時間逐漸縮短,由2分27秒縮短為2分1秒,硫化曲線中扭矩逐漸降低,表示交聯效率降低,而硫化曲線中ML及MH也同步下降,由17.35 lbf/in降低至15.84 lbf/in;原因是分散劑添加量過多所導致,必須控制在1~3 phr之間或分散劑添加量全部固定為1 phr。
在NBR/碳黑/蒙脫土系統及NBR/碳黑/PEG/蒙脫土系統添加碳黑20 phr會大幅提升物理性質,例如:抗拉強度提昇、DIN磨耗大幅度降低,使得蒙脫土添加的差異性被掩蓋,造成不易辨識奈米蒙脫土所構成的特性。

In is research, the mechanical properties of the nitrile rubber (NBR) were studied by adding the commercial organic clays Cloisite 30B and Cloisite 15A montmorillonite (MMT). Three systems were investigated. These were the NBR/MMT, the NBR/carbon black/MMT and the NBR/carbon black/PEG dispersant/MMT systems.
These NBR/MMT nanocomposites were obtained by using high-shear mixer XRD, the rubber Rheometer , Mooney viscometer and universal testing machine were used to analyze the NBR/MMT nanocomposites.
In the tensile test, the NBR/montmorillonite system gives the tensile stress of the control group of 36 kgf/cm2. In the control group, the NBR/C30B1 gives the tensile stress which reduces to 20 kgf/cm2 and declines nearly 45 %. The elongation reduces from 793 % to 643 %. The total decrease of 19 % via double roller decentralized operations is due to the particles agglomeration for C30B. From the test data, we assume that the surface treatment agent of MT2EtOH gives C30B with two-OHs and forms hydrogen bonds between clay platelets. Agglomeration is the main cause for the substantial decline in mechanical properties.
The tensile strength of NBR/C15A1 blend, containing C15A 1 phr, increases from 36 to 51 kgf/cm2, a 39 % difference compared with the control. The elongation increses from 793 % to 859 % which is slightly higher of 8 %. In the NBR/carbon black/ MMT system, the abration increases from 162 mm3 to 166 mm3. The abration decreases from 162 to 106 after adding 1phr C15A1 with a decrease of 35 percent compared with the control.
For the systems studied, we find that for the NBR with 1 phr MMT, the difference of physical properties ranging from 19 % to 45 %. The key point is the montmorillonite modifier. According to XRD, its pattern shows apparent diffraction peaks and exhibits intercalated structure.
