摘要: 将水合肼与氧化石墨烯(GO)在特定条件下进行反应，通过水合肼的还原作用，成功制得还原氧化石墨烯(RGO)。随后，将RGO与溶聚丁苯橡胶(SSBR)进行胶液搅拌混合，利用高温煮出工艺，使RGO均匀分散在SSBR胶液中。对制备的RGO/白炭黑/SSBR纳米复合材料进行性能测试。结果显示，RGO的加入显著提高了材料的力学性能，拉伸强度从10.7 MPa提升至13.1 MPa，提高约22.4%，硬度从65提高至68，这主要归因于RGO与橡胶基体之间的良好界面相互作用以及其优异的力学增强效果。同时，白炭黑的协同作用进一步优化了材料的耐磨性，磨耗从0.432 cm3减少到0.332 cm3，下降幅度23.2%。此外，通过动态力学分析发现，复合材料在0℃时抗湿滑性能和60℃时滚动阻力均有所改善，使其在高性能橡胶制品领域具有广阔的应用前景。
Abstract: Hydrazine hydrate and graphene oxide (GO) were reacted under specific conditions. Through the reduction effect of hydrazine hydrate, reduced graphene oxide (RGO) was successfully prepared. Subsequently, RGO was mixed with solution-polymerized styrene-butadiene rubber (SSBR) by stirring the rubber solution. The high-temperature cooking process was used to evenly disperse RGO in the SSBR solution. The performance of the prepared RGO/silica/SSBR nanocomposites was tested. The results showed that the addition of RGO significantly improved the mechanical properties of the material. The tensile strength increased from 10.7 MPa to 13.1 MPa, an increase of approximately 22.4%, and the hardness increased from 65 to 68. This was mainly attributed to the good interfacial interaction between RGO and the rubber matrix and its excellent mechanical reinforcing effect. At the same time, the synergistic effect of silica further optimized the wear resistance of the material, with the abrasion decreasing from 0.432 cm3 to 0.332 cm3, a reduction of 23.2%. In addition, dynamic mechanical analysis revealed that the wet skid resistance at 0˚C and the rolling resistance at 60˚C of the composite material were both improved, indicating a broad application prospect in the field of high-performance rubber products.
