采用在废旧轮胎胶粉熔融挤出过程中提高双螺杆挤出机螺杆转速的高剪切应力诱导方法，研究了双螺杆挤出机的螺杆转速、挤出反应温度及脱硫促进剂品种对轮胎胶脱硫共混物的熔体流动速率、凝胶含量、溶胶红外吸收光谱的影响；对脱硫轮胎胶（DGTR）/高密度聚乙烯（HDPE）/三元乙丙橡胶(EPDM)动态硫化热塑性弹性体力学性能的影响及其制备的工艺条件进行考察。研究了亚临界水结合高剪切应力对轮胎胶应力诱导脱硫的影响。实验结果表明：
（1）在轮胎胶粉与HDPE的熔融挤出高剪切应力诱导脱硫反应过程中，高转速同向双螺杆挤出机的高剪切作用，可诱发废旧轮胎胶混合物中交联网络的断链和解交联反应，引起脱硫共混物凝胶含量的下降、未熔融凝胶颗粒尺寸的减小以及熔体流动速率的增加；挤出机螺杆转速越快、挤出反应温度越高，这种断链和解交联反应越明显。
（2）在轮胎胶粉与HDPE的熔融挤出高剪切应力诱导脱硫反应过程中，促进剂仲丁醇、多烷基苯酚二硫化物（420或450）及正丁胺均具有明显促进脱硫化反应的作用，引起了脱硫反应产物溶胶中丁苯橡胶成分的明显增加。四种促进剂相比较，450或正丁胺作为促进剂的脱硫效果较好，并引起脱硫产物凝胶含量的下降、熔体流动速率的上升及动态交联热塑性弹性体力学性能的明显改善。
（3）在采用脱硫共混物与EPDM制备DGTR/HDPE/EPDM动态交联热塑性弹性体的过程中，选择DCP为主交联剂，S为辅助交联剂时，此动态交联体系的交联效果最优。
（4）在正丁胺作为脱硫反应促进剂的最佳脱硫反应条件（240℃和1000r/min）下，高剪切应力诱导脱硫反应所得脱硫共混物的凝胶含量可达26.1%，熔体流动速率可达9.2g/10min。 动态硫化时选择DCP为2phr，S为0.5phr的复合交联体系，硫化时间为10分钟时所得材料力学性能较佳。在此条件下，DGTR/HDPE/EPDM（40/40/20）动态硫化热塑性弹性体材料的拉伸强度和断裂伸长率分别达到12.5Mpa和440.6%。
（5）采用亚临界水挤出法应力诱导废旧轮胎胶脱硫化反应，将高剪切应力诱导解交联反应技术与亚临界流体分解、降解的解交联反应技术相结合，这两种作

用可产生协同效应，降低了交联键发生断裂的活化能，提高了交联网络断裂效率，从而得到更好的脱硫效果。
（6）亚临界水挤出法应力诱导废旧轮胎胶粉与HDPE的熔融挤出脱硫反应过程中，挤出机螺杆转速越快、挤出反应温度越高以及亚临界水压力越大，轮胎胶粉交联网络受到的机械剪切应力和热能作用越强，亚临界水对轮胎胶交联网络的溶解和解交联反应作用也明显增强，这两种作用的协同解交联反应，引起脱硫共混物凝胶含量的下降和熔体流动速率的提升，引起脱硫共混物溶胶中双键特征吸收峰强度明显增大以及热塑性弹性体材料力学性能的明显改善。
（7）在亚临界水挤出法应力诱导废旧轮胎胶粉与HDPE的熔融挤出脱硫反应过程中，正丁胺作为脱硫促进剂时，脱硫共混物凝胶含量下降明显，熔体流动速率上升，动态交联热塑性弹性体材料中未熔融的凝胶粒子尺寸较小，力学性能明显改善。在正丁胺作为脱硫促进剂的最佳脱硫反应条件（220℃，1000rpm，2.4MPa）下，亚临界水挤出法所得脱硫共混物制备DGTR/HDPE/EPDM热塑性弹性体的拉伸强度和断裂伸长率分别达到12.8MPa和614.6%。

看楼主够诚意，花了一个多小时翻译了一下，仅供参考，非机械力化学专业，但曾经翻阅过双螺杆挤出的资料。翻译的不好，您再找同行多改改吧。
During the melting extrusion process for the powder of waste tire rubber, a high shear stress induced effects could be obtained by increasing the screw speed of Twin-screw extruder. On the one hand, the effects of the screw speed, extrusion reaction temperature and desulfurization accelerator varieties on the melt flow rate of the tire rubber desulfurization blends, gel content, infrared absorption spectra of the sol were systematically investigated. On the other hand, the dynamic mechanical properties of the dynamically Vulcanized Thermoplastic Elastomer-Desulfurization Tire Glue (DGTR) / High Density Polyethylene (HDPE) / Ethylene Propylene Diene Monomer (EPDM) rubber and its preparation conditions were examined. Besides, the effects of subcritical water combined with high shear stress on the stress-induced desulfurization for tire rubber was also included. The following conclusions could be made:
(1) During the melting extrusion process for the mixture of the tire crumb rubber and HDPE, the desulfurization reaction could be induced by high shear stress inside. In fact, the high-speed shearing in twin-screw extruder can induce waste tire rubber mixture reconciliation crosslinking reaction and chain scissions in network, causing the decline of the gel content of melting desulfurization blends, decrease of particle sizes of solid and increase of the melt flow rate. The faster the extruder screws speed, higher the extrusion reaction temperature and reconciliation rates of this broken crosslinking chain;
(2) During the desulfurization reaction induced by high shear stress in the tire crumb rubber and HDPE melt extrusion process, the promotion agent butanol, multi-alkyl phenol disulfide (420 or 450) and n-butylamine significantly improved the desulfurization reaction. This caused a significant increase in styrene-butadiene rubber content in the desulfurization reaction products sol. 450 or n-butylamine accelerator are considered better due to greater desulfurization effects, which decreased the gel content for the desulfurization products, while increased the melt flow rate. In this way, mechanical performance of the dynamically crosslinked thermoplastic elastomer was significantly improved.
(3) In the preparation process of thermoplastic elastomer DGTR/HDPE/EPDM by using cross-linking desulfurization blends and the EPDM, the DCP-based crosslinking agent was selected, and S was used as the secondary cross-linking agent. In this way, the dynamic crosslinking system was found to be the best.
(4) During the desulfurization reactions, in which n-butylamine was used as the accelerator with the reaction conditions (240 °C and 1000 r/min), the gel content of desulfurization blends after the desulfurization reaction induced by high shear stress could arrive at 26.1% and the melting body flow rate could go up to 9.2g/10min. During the Dynamically vulcanized process, the 2phr DCP with 0.5phr S crosslinked system was selected, based on which the curing time should be 10 minutes to obtain a better mechanical properties. Under these conditions, tensile strength and fracture elongation of dynamically vulcanized thermoplastic elastomer DGTR/HDPE/EPDM (40/40/20) was tested as 12.5MPa and 440.6 %, respectively.
(5) Subcritical water extrusion method was used in stress-induced desulfurization reaction for waste tire rubber, in which the technique of high shear stress induced decomposition cross-linking reaction and subcritical fluid decomposition was combined to reduce the cross-linked bond rupture activation energy due to synergistic effects. In fact, this could improve the efficiency of cross-linked network fracture, resulting in better desulfurization output.
(6) During the process of the stress induced desulfurization reaction of the scrap tire rubber powder and HDPE melt by the sub-critical water extrusion method, the faster the extruder screw speed, the higher extrusion reaction temperature and the greater the pressure of subcritical water. In this way, the tire crumb rubber cross-linked network by mechanical shear stress and thermal effect is stronger, and subcritical water dissolved reconciliation of tire rubber cross-linked network crosslinking reaction effect is also significantly enhanced. After the synergy of these two solutions cross-linking reaction, caused by desulfurization blends of the decline of the gel content and increase of the melt flow rate, the double bond in the desulfurization blends Sol characteristic absorption peak intensity was increased significantly. At the same time, of the mechanical properties of thermoplastic elastomer material was significantly improved.
(7) In stress-induced desulfurization reaction process for scrap tire rubber powder and HDPE melts, the subcritical water extrusion method was used and n-butylamine was selected as the accelerator of the desulfurization, which significantly decreased the gel content, and increased flow rate of the melt gel. The particle size of the dynamically crosslinked thermoplastic elastomer material that does not melt is smaller, and its mechanical properties was significantly improved. When butylamine was used as an accelerator of desulfurization, under the reaction a certain condition (220 °C, 1000rpm, 2.4MPa), the tensile strength and elongation at break of obtained thermoplastic elastomer DGTR/HDPE/EPDM were tested as 12.8MPa and 614.6%, respectively.
