| 中文摘要: |
| 研究螺杆挤出机在白炭黑填充橡胶混炼中的应用效果。结果表明：相对传统密炼机，螺杆挤出机通过强剪切作用和排气功能，显著降低了白炭黑填充橡胶的门尼粘度，同时提高了白炭黑的硅烷化反应程度和分散效果；螺杆挤出机混炼的胶料在Payne效应、硫化特性、物理性能、耐磨性能和动态力学性能方面均较优，特别是0 ℃时的损耗因子的增大，显著提高了轮胎的抗湿滑性能。本研究可为绿色轮胎的高性能化提供新的技术思路，并为螺杆挤出机在轮胎行业的扩大应用提供理论依据。 |
| 英文摘要: |
| The application effects of a screw extruder in the mixing of silica-filled rubber were investigated.The results showed that compared to a traditional internal mixer，the screw extruder significantly reduced the Mooney viscosity of silica-filled rubber through strong shear action and venting functions，while also improving the silanization reaction degree and dispersion of silica.The compound mixed by the screw extruder exhibited superior performance in terms of Payne effect，vulcanization characteristics，physical properties，wear resistance and dynamic mechanical properties，particularly the improvement in the loss factor at 0 ℃，which significantly enhanced the wet skid resistance of tires.This research could provide new technical insights for the high-performance development of green tires and offer a theoretical basis for the expanded application of screw extruders in the tire industry. |
