| 中文摘要: |
| 以自制的单羟基封端二甲基硅油和低含氢硅油为原材料，采用皮尔斯-罗宾逊反应“一锅法”制备超支化结构硅油，在对超支化硅油结构与性能分析的基础上，研究其对中苯基硅橡胶性能的影响。结果表明：超支化硅油具有良好的热稳定性，其流变性能接近牛顿流体；超支化硅油具有内增塑作用，可以提高中苯基硅橡胶的弹性，降低动力学损耗。 |
| 英文摘要: |
| In this study，hyperbranched silicone oil was prepared by Piers-Rubinsztajn reaction in one potand using lab-made single hydroxyl terminated dimethyl silicone oil and low hydrogen silicone oil as raw materials. The structure and properties of the hyperbranched silicone oil were analyzed，and its influence on the properties of phenyl silicone rubber with medium phenyl content was studied. The results showed that hyperbranched silicone oil had good thermal stability and its rheological properties were close to Newtonian fluids. Hyperbranched silicone oil had internal plasticizing effect，and could improve the elasticity of phenyl silicone rubber and reduce the dynamic loss. |
