摘要

介绍了一种炭黑填充型氯丁橡胶(CR)胶料的成分分析方法。实验数据与实际值吻合较好。该方法是基于三个实验，即热重分析、溶剂萃取和新开发的硫化CR化合物在镍催化剂存在下的热和热氧化降解。热重分析实验给出了橡胶胶料中无机物的含量。溶剂萃取得到可萃取量。热氧化降解实验给出了聚合物的用量。在热氧化降解实验中，用摩尔法滴定游离氯离子，由氯含量反算CR的量。

Composition Analysis of Carbon Black-Filled Polychloroprene Rubber Compound by Thermo-Oxidative Degradation of the Compound

This study describes a method for the composition analysis of the carbon black-filled polychloroprene rubber (CR) compound. Good agreement of the experimental data with the actual value was found. The method is based on three experiments namely thermogravimetric analysis, solvent extraction, and newly developed thermo and thermo-oxidative degradation of the vulcanized CR compound in the presence of nickel catalyst. Thermogravimetric analysis experiment gives the amount of inorganic material in the rubber compound. Solvent extraction gives the extractable amount. Thermo-oxidative degradation experiment gives the polymer amount. In thermo-oxidative degradation experiment, liberated chloride ion was titrated by Mohr’s method, and the amount of CR was back calculated from the chlorine content.
