浅色橡胶油溶解度参数的估算及应用

Estimation of Solubility Parameter of Light Color Rubber Oil and Its Application

以Hildebrand提出的溶解度参数为基础,结合试验经验推导出通过表面张力估算浅色橡胶油溶解度参数的拟合公式。采用该公式计算了11种常用弱极性溶剂和8种浅色橡胶油的溶解度参数,并与其文献值进行对比,验证了橡胶油溶解度参数拟合公式的可靠性。该公式采用现有国家标准和石油石化行业标准测试基本数据,易于在化工行业推广。利用橡胶油溶解度参数估算结果可以很好地预测充油橡胶的吸油能力、充油胶中橡胶油的稳定性等,对橡胶配方设计工作具有指导意义。

In this work,a fitting formula for estimation of the solubility parameter of light color rubber oil by surface tension was established based on Hildebrand solubility parameter theory and experimental testing results. The solubility parameters of 11 solvents with weak polarity and 8 light color rubber oils were calculated by the formula,and compared with their literature values. The results verified the reliability of thisformula. The basic data of the formula was tested according to existing national standards and petrochemical industry standards. Therefore,the fitting formula could be easily applied in the petrochemical industry. The solubility parameter of rubber oil was useful to predict the oil absorption ability of the oil-filled rubber and the stability of the rubber oil,which was an effective tool in rubber formulation design.
