中文摘要: |
分别制备不同相对分子质量和游离酚含量的热塑性苯酚甲醛树脂,并测试添加这些树脂的天然橡胶(NR)的加工性能。结果表明:热塑性苯酚甲醛树脂的相对分子质量对胶料的焦烧时间和门尼粘度有一定影响,树脂的相对分子质量增大,胶料的焦烧时间趋于延长,门尼粘度有增大趋势;热塑性苯酚甲醛树脂中游离酚含量对胶料硫化时间和门尼粘度有影响,树脂中游离酚含量增加,胶料的硫化时间趋于缩短,门尼粘度有减小趋势。 |
英文摘要: |
Thermoplastic phenolic-formaldehyde resins with different molecular weight and free phenol content were prepared,and the processing properties of natural rubber (NR) compounds with the resins were tested.The results showed that,the molecular weight of thermoplastic phenolic-formaldehyde resin had some effects on the scorch time and Mooney viscosity of the compound.For example,the compound with high molecular weight resin had longer scorch time and higher Mooney viscosity.The free phenol content of thermoplastic phenolic-formaldehyde resin had effects on the vulcanization time and Mooney viscosity of the compound.It was found that the compound with the resin having high content of free phenol had shorter vulcanization time and lower Mooney viscosity. |
