The recycling of leather solid waste not only involves resource utilization and environmental protection but also has important significance for the sustainable development of the leather industry. In this paper, the leather waste was crushed into fibers, which were stabilized and mixed with nitrile-butadiene rubber (NBR). The mixture was milled and vulcanized and a composite NBR-SLF (Stabilized Leather Fiber) is prepared for sealing material. The physical and mechanical properties, water resistance, oil resistance and aging resistance of NBR-SLF were tested and analyzed. It is found that the optimized NBR-SLF not only reduces the cost of raw material, but also changes the physical and mechanical performance of NBR. As a sealing material, it satisfies the substitution of NBR in terms of hardness and thermal stability. Especially the anti-aging ability is better than NBR.

丁腈橡胶与皮革纤维混合的复合材料和功能特性的研究

皮革固体废弃物的回收利用不仅涉及资源利用和环境保护，对于皮革工业的可持续发展也具有重要意义。本文将皮革废料粉碎成纤维，然后将其稳定并与丁腈橡胶（NBR）混合。将混合物研磨并硫化，然后准备复合NBR-SLF（稳定的皮革纤维）作为密封材料。对NBR-SLF的物理机械性能，耐水性，耐油性和耐老化性进行了测试和分析。发现优化的NBR-SLF不仅降低了原材料成本，而且改变了NBR的物理和机械性能。作为密封材料，就硬度和热稳定性而言，它满足了NBR的替代要求。
