红外光谱法鉴定并用橡胶成分

Identification of Blend Compound by FT-IR Spectrometry

应用红外光谱法研究并用橡胶体系中各种成分的定性分析。对并用橡胶体系的红外光谱进行分析得出,可通过各种橡胶的特征峰进行并用胶成分定性鉴定,在由Ⅰ、Ⅱ组成的二元并用橡胶体系中,随着并用比增大,Ⅰ的特征官能团含量增大,Ⅱ的特征官能团含量减少,所对应的吸光度比值(AⅠ/AⅡ)也随之增大。

Blend compound is identified by FT-IR spectrometric. The results show that blend compound is identified through characteristic peaks of different kinds of rubber. When the quality ratio of rubber I and rubber II decreases, the content of characteristic functional group of rubber I increases and the content of characteristic functional group of rubber II decreases, the absorbance ratio of rubber I and rubber II （A I/A II ） also increases.
