| 中文摘要: |
| 采用差示扫描量热（DSC）法研究钴盐粘合增进剂硼酰化钴、癸酸钴和硬脂酸钴的热稳定性，用Ozawa方程和Kissinger方程计算活化能。结果表明：根据DSC曲线，用Ozawa方程和Kissinger方程求得的钴盐粘合增进剂的活化能相近，线性相关因数都在0.998以上；3种钴盐粘合增进剂热稳定性从高到低依次为硼酰化钴、癸酸钴、硬脂酸钴。DSC法测定橡胶助剂的热稳定性具有快速、准确和高效的特点。 |
| 英文摘要: |
| The thermal stability of several cobalt salts， cobalt boroacylate， cobalt decanoate， cobalt stearate， which were used as adhesion promoter， was investigated by using differential scanning calorimetry (DSC)， and the activation energy of thermal degradation was calculated by Ozawa equation and Kissinger equation. By either equation， the linear correlation coefficient was over 0.998， and the calculated result was about the same. The experimental results showed that cobalt boroacylate possessed the highest thermal stability， followed by cobalt decanoate， while cobalt stearate had the lowest thermal stability. This method was fast， accurate and efficient to determine the thermal stability of rubber additives. |
