摘要采用傅里叶变换红外光谱（FTIR）-衰减全反射光谱（ATR）研究了锌活化硫磺硫化顺式-1，4-聚异戊二烯（IR）中二氧化硅填料的相互作用。检查的变量是增加的二氧化硅水平和批次的混合质量。增加的二氧化硅水平导致带变宽和向二氧化硅吸收区域（1250-1000 cm-1）的较低波数的频移，这是由于橡胶和部分固化体系在二氧化硅表面上的物理和化学吸附的组合。在1040和1017 cm−1附近出现的峰归因于二氧化硅和天然橡胶之间的物理相互作用。然而，由于在研磨过程中发生的自由基反应，存在IR的一些化学键合。根据上述结果，低效混合具有与添加较少填料相当的影响。也就是说，有较少的“有效”的填料在混合不好的样品，因为穷人的迪…
Abstract The interactions of silica filler in zinc activated, sulfur vulcanized cis-1,4-polyisoprene (IR) were characterized using Fourier Transform Infrared (FTIR)-Attenuated Total Reflectance (ATR) spectroscopy. The variables examined were increased levels of silica and quality of mixing of the batch. The increased silica level resulted in band broadening and a frequency shift to lower wavenumbers of the silica absorbance region (1250-1000 cm−1) due to a combination of physical and chemical adsorption of the rubber and parts of cure system on the silica surface. The peaks that appeared near 1040 and 1017 cm−1 were attributed to physical interactions between silica and the natural rubber. However some chemical bonding of the IR was present as a result of a free radical reaction that takes place during the milling process. Inefficient mixing had an affect comparable to adding less filler, according to the results above. That is, there was less “effective” filler in the poorly mixed samples because poor di...
