| 中文摘要: |
| 对三元乙丙橡胶（EPDM）混炼胶的各组分进行分离并对配方进行分析。以正庚烷溶解EPDM混炼胶，将其有机组分与无机组分分离；有机组分在甲醇中沉淀后经二氯甲烷抽提，将EPDM与石蜡油分离；以盐酸溶解无机组分，将碳酸盐和氧化锌与白炭黑分离；采用核磁共振氢谱、核磁共振扩散序谱、傅里叶红外光谱、X-射线衍射谱和X-射线光电子能谱，对各组分进行定性和定量分析，建立一套EPDM混炼胶组分的分析方法，有助于EPDM混炼胶的生产过程质量监控和配方改进。 |
| 英文摘要: |
| The components of ethylene-propylene-diene rubber（EPDM） compound were separated and it formulation was analyzed. EPDM compound was dissolved in n-hexane to separate its organic and inorganic components. The organic components were precipitated in methanol and extracted with dichloromethane to separate EPDM from paraffin oil. The inorganic components were dissolved in hydrochloric acid to separate carbonate and zinc oxide from silica. The nuclear magnetic resonance hydrogen spectroscopy，nuclear magnetic resonance diffusion ordered spectroscopy，Fourier transform infrared spectroscopy，X-ray diffraction spectrum and X-ray photoelectron spectroscopy were used to qualitatively and quantitatively analyze each component，and a set of analysis method for the components of EPDM compound was established，which was helpful for quality monitoring in the production process of EPDM compound and its formulation improvement. |
