摘要

本研究探讨了橡胶复合材料与碳纳米管结合的性能,以改善其在硫化过程中的物理化学特性,从而提高篮球的质量。天然橡胶和丁基橡胶以 7:3 的比例混合,制备橡胶复合材料。随后,将橡胶复合材料与碳纳米管混合。结果表明,采用湿法混合制备的橡胶纳米复合材料具有耐热老化性。此外,纳米橡胶复合材料还具有优异的硫化特性,可使纳米橡胶复合材料的硫化时间缩短 10%以上。此外,纳米橡胶复合材料还具有良好的相容性和机械性能,如断裂伸长率、硬度、膨胀系数和交联密度。值得注意的是,在高硫和低硫条件下,纳米橡胶复合材料拉伸强度的下降幅度明显小于正常条件下的下降幅度,这表明该纳米橡胶复合材料的抗弯强度得到了大幅提高。总之,制备的橡胶纳米复合材料的机械性能得到了改善,这对提高橡胶篮球的质量和促进橡胶制品的应用具有重要意义。

The performance improvement of basketball shell prepared with nanomaterials modified rubber supported by wet mixing method
This study investigates the performance of rubber composite combined with carbon nanotubes to improve its physicochemical properties during the vulcanization process, thereby improving the quality of basketballs. Natural rubber and butyl rubber were mixed in a 7:3 ratio to prepare a rubber composite. Subsequently, the rubber composite was mixed with carbon nanotubes. The results demonstrate that the rubber nanocomposite prepared using wet mixing exhibits thermal aging resistance. Furthermore, the rubber nanocomposite demonstrates excellent vulcanization characteristics, which can achieve a reduction in the cure time of the rubber nanocomposite exceeding 10%. Additionally, the rubber nanocomposite shows good compatibility and mechanical properties, such as elongation at break, hardness, swelling coefficient, and cross-linking density. Notably, under high sulfur and low sulfur conditions, the decrease in tensile strength of the rubber nanocomposite is significantly smaller compared to that under the normal conditions, indicating a substantial enhancement in flexural resistance for this rubber nanocomposite. In conclusion, the prepared rubber nanocomposite shows an improvement in mechanical properties, which holds valuable implications for enhancing the quality of rubber basketballs and promoting applications of rubber products.
