| Abstract: |
| On the basis of the solubility parameter proposed by Hildebrand and the experimental experience，a fitting formula for estimating the solubility parameter of light color rubber oil by surface tension was established. 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 reliability of this formula was verified. The basic data of the formula were tested according to existing national standards and petrochemical industry standards，therefore，the fitting formula was easy to spread and apply in 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，et al. The solubility parameter fitting formula was an effective method in rubber recipe design. |
