| 中文摘要: |
| 对单萜烯环保溶胀助剂与超临界二氧化碳（ScCO2）协同溶胀废橡胶（废橡胶轮胎胎面胶条）的再生（低温机械力-化学再生）工艺条件进行试验研究。结果得出，单萜烯环保溶胀助剂与ScCO2协同溶胀废橡胶（在高压反应釜中）的再生优化工艺条件为：单萜烯环保溶胀助剂用量 2份，反应温度 100～120 ℃，反应压力 8～10 MPa，反应时间 15～20 min。与传统废橡胶再生工艺相比，单萜烯环保溶胀助剂与ScCO2协同溶胀废橡胶的再生工艺制备的再生橡胶胶料在门尼粘度、硫化特性、拉伸性能和动态力学性能等方面均具有明显优势。 |

| The regeneration（low-temperature mechanical-chemical regeneration） process conditions of waste rubber（waste rubber tire tread compound strip） based on monoterpene environmentally friendly swelling additive and supercritical carbon dioxide（ScCO2） synergistic swelling were experimentally studied.The results showed that the optimized regeneration process conditions of waste rubber（in a high-pressure reaction vessel） based on monoterpene environmentally friendly swelling additive and ScCO2 synergistic swelling were as follows：the dosage of monoterpene environmentally friendly swelling additive 2 phr，reaction temperature 100～120 ℃，reaction pressure 8～10 MPa，reaction time 15～20 min.Compared recycled rubber compounds prepared by the traditional regeneration process of waste rubber，the recycled rubber compounds prepared by the regeneration process of waste rubber based on monoterpene environmentally friendly swelling additive and ScCO2 synergistic swelling exhibited significant advantages in terms of Mooney viscosity，vulcanization characteristics，tensile properties and dynamic mechanical properties. |
