A novel filler for rubber was prepared by deep processing of coal gasification fine slag (CGFS) using an airflow sorter. Five processed CGFS samples with different sizes and carbon contents were obtained. The effects of particle size, unburned carbon, and surface properties of CGFS on the comprehensive properties of filled styrene butadiene rubber (SBR) were investigated. The mechanical properties were improved with decreasing CGFS size, and the curing and mechanical properties exhibited better performance owing to the unburned carbon. Unburned carbon can improve the dispersion properties of the filler and the compatibility between the matrix and filler. The best values for the curing characteristics and mechanical properties of SBR appeared when CGFS-S2 and CGFS-S3 were used as the fillers, respectively. Heavy calcium carbonate (CaCO 3 ) particles were used as a comparative filler, and the results demonstrated that CGFS particles have the potential to replace CaCO 3 in rubber. A novel method for preparing coal gasification fine slag (CGFS) samples utilized as a reinforcing filler for the SBR matrix through an efficient pneumatic separation technique has been demonstrated. The superior filler–rubber interfacial interaction can contribute to significant reinforcement in the comprehensive performances of composites by the addition of CGFS series fillers into the SBR matrix. CGFS particles have great potential for application in rubber composites, and a new strategy of using CGFS as fillers has been established.

煤气化细渣气选技术制备低成本、高价值的丁苯橡胶补强填料

采用气流分选机对煤气化细渣（CGFS）进行深加工制备了一种新型橡胶填料。获得了五个不同尺寸和碳含量的加工过的 CGFS 样品。研究了CGFS的粒径、未燃碳和表面性能对填充丁苯橡胶（SBR）综合性能的影响。随着CGFS尺寸的减小，机械性能得到改善，并且由于未燃烧的碳，固化和机械性能表现出更好的性能。未燃炭可以提高填料的分散性能和基体与填料的相容性。当分别使用 CGFS-S2 和 CGFS-S3 作为填料时，SBR 的固化特性和机械性能的最佳值出现。使用重质碳酸钙 (CaCO 3 ) 颗粒作为对比填料，结果表明 CGFS 颗粒具有替代橡胶中 CaCO 3 的潜力。已经证明了一种通过有效的气动分离技术制备用作 SBR 基质增强填料的煤气化细渣 (CGFS) 样品的新方法。通过将 CGFS 系列填料添加到 SBR 基体中，优异的填料-橡胶界面相互作用有助于显着增强复合材料的综合性能。CGFS颗粒在橡胶复合材料中具有巨大的应用潜力，已经建立了一种以CGFS作为填料的新策略。已经证明了一种通过有效的气动分离技术制备用作 SBR 基质增强填料的煤气化细渣 (CGFS) 样品的新方法。通过将 CGFS 系列填料添加到 SBR 基体中，优异的填料-橡胶界面相互作用有助于显着增强复合材料的综合性能。CGFS颗粒在橡胶复合材料中具有巨大的应用潜力，已经建立了一种以CGFS作为填料的新策略。已经证明了一种通过有效的气动分离技术制备用作 SBR 基质增强填料的煤气化细渣 (CGFS) 样品的新方法。通过将 CGFS 系列填料添加到 SBR 基体中，优异的填料-橡胶界面相互作用有助于显着增强复合材料的综合性能。CGFS颗粒在橡胶复合材料中具有巨大的应用潜力，已经建立了一种以CGFS作为填料的新策略。通过将 CGFS 系列填料添加到 SBR 基体中，优异的填料-橡胶界面相互作用有助于显着增强复合材料的综合性能。CGFS颗粒在橡胶复合材料中具有巨大的应用潜力，已经建立了一种以CGFS作为填料的新策略。通过将 CGFS 系列填料添加到 SBR 基体中，优异的填料-橡胶界面相互作用有助于显着增强复合材料的综合性能。CGFS颗粒在橡胶复合材料中具有巨大的应用潜力，已经建立了一种以CGFS作为填料的新策略。
