摘要
研究不饱和脂肪酸锌皂类加工助剂硬酯酸锌、增塑剂A和加工助剂HA60对天然橡胶(NR)性能的影响。结果表明:加入不饱和脂肪酸锌皂类加工助剂,NR胶料的门尼粘度显著降低,硫化速度加快,炭黑分散性和抗硫化返原性能提高;随着脂肪酸锌皂类加工助剂不饱和度增大(不饱和度由小到大的顺序为硬脂酸锌、增塑剂A和加工助剂HA60),NR胶料的门尼粘度增大,炭黑分散性能提高,抗硫化返原性能提高,耐热老化性能降低。
In this study, the inlfuence of zinc salts of fatty acid, speciifcally, zinc stearate, plasticizer A and processing aid HA60, on the properties of NR was investigated. The results showed that with zinc salts of fatty acid, the Mooney viscosity of NR compound was signiifcantly reduced, the curing speed increased, and the dispersion of carbon black and anti-reversion property were improved. It was found that when the unsaturation degree of the fatty acid increased, which was in the order of zinc stearate < plasticizer A < HA60, the Mooney viscosity of NR compound increased, the dispersion of carbon black was improved, anti-reversion property was improved, but the heat aging resistance decreased.
