Abstract

In this study, the lipid contents of different kinds of natural rubber were measured by attenuated total reflection–Fourier transform infrared spectroscopy. The correlation between these amounts were considered with the tensile properties of natural rubber compounds. The Pearson correlation coefficients were more than −0.9 for all cases, which confirms that the models are acceptable. These models were applied for the estimation of tensile properties in the case study. It was observed that the tensile strength, elongation at break, modulus 100%, and modulus 300% can be predicted by errors of about 4%, 17%, 18%, and 18% respectively. This is a simple, fast, and nondestructive way to estimate the tensile properties before the compound preparation.

摘要

本研究采用衰减全反射-傅里叶变换红外光谱法测定不同种类天然橡胶的脂质含量。这些量之间的相关性被认为与天然橡胶化合物的拉伸性能有关。所有案例的 Pearson 相关系数均大于 −0.9，这证实了模型是可以接受的。在案例研究中，这些模型被用于估计拉伸性能。据观察，拉伸强度、断裂伸长率、模量 100% 和模量 300% 的预测误差分别约为 4%、17%、18% 和 18%。这是一种在化合物制备前评估拉伸性能的简单、快速且无损的方法。
