橡胶材料具有广泛的商业应用，例如婴儿尿布、饥荒卫生用品、药物输送装置和失禁产品（例如橡胶管、七弦琴等）。在目前的工作中，对一些选定的橡胶材料（天然橡胶（NR）、苯乙烯丁二烯橡胶（SBR）、丁腈橡胶（NBR）和三元乙丙橡胶（EPDM））的机械性能进行了研究，即在三种状态下进行，即生胶、生胶、三元乙丙橡胶。硫化和增强。为了提高橡胶弹性体的质量，人们尝试制备称为聚合物共混物的新型弹性体。在本研究中，尝试将 NR 与 NBR 和 EPDM 混合。我们在这里报告了一种评估各种物理机械性能（例如机械强度、拉伸强度、伸长率和硬度）的新方法。该方法简单、直接、快速，并涉及红外光谱测量来评估这些特性。随着现代红外光谱的应用，通过计算FTIR光谱获得的甲基和亚甲基振动频率之间的内标，分析了这些橡胶材料的机械强度。还通过万能试验机进行拉伸强度测量。本研究中通过基于红外的方法获得的橡胶衍生物的物理机械性能结果与标准方法得出的数据非常一致。 (C) 2006 Elsevier B.V. 保留所有权利。
Rubber materials have wide range of commercial applications such as, infant diapers, famine hygiene products, drug delivery devices and incontinency products such as rubber tubes, lyres, etc. In the present work, studies on mechanical properties of some selected rubber materials viz., natural rubber (NR), styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR) and ethylene propylene diene monomer (EPDM) have been carried out in three states viz., raw, vulcanized and reinforced. To enhance the quality of rubber elastomers, an attempt is made to prepare new elastomers called polyblends. In the present study an attempt is made to blend NR with NBR and with EPDM. We here report, a novel approach for the evaluation of various physico-mechanical properties such as mechanical strength, tensile strength, elongation and hardness. The method is simple, direct and fast and involves infrared spectral measurements for the evaluation of these properties. With the applications of modern infrared spectroscopy, the mechanical strength of these rubber materials have been analyzed by calculating the internal standards among the methyl and methylene group vibrational frequencies obtained from FTIR spectroscopy. Also the tensile strength measurements carried out by universal testing machine. The results pertaining physico-mechanical properties of the rubber derivatives undertaken in the present study obtained by IR-based method are in good agreement with data resulted from the standard methods.
