玄武岩纤维增强聚丙烯回料性能衰减规律与循环利用研究

Research on the Performance Attenuation Law and Recycling of Basalt Fiber Reinforced Polypropylene Recycled Materials

摘要: 为应对汽车制造业对材料循环利用的迫切需求，本文系统研究了玄武岩纤维增强聚丙烯新材料在经历多次物理粉碎与再注塑后的性能衰减规律。通过对15% BF + PP材料进行至多5次的循环再生处理，并测试其关键力学性能，结果表明：经历3次循环后，材料综合性能保持率仍高于78%；经历5次循环后，性能保持率稳定在77.8%以内。本研究证实，BF + PP回料具有卓越的性能稳定性，能够满足主流主机厂对回料使用的严苛标准，为在汽车零部件中大规模应用回料、减少原生材料消耗与工业废料提供了可靠的数据支撑与解决方案。

Abstract: To address the urgent demand of the automotive manufacturing industry for material recycling, this paper systematically studies the performance degradation law of basalt fiber reinforced polypropylene new materials after multiple physical crushing and re-injection molding. Through the recycling treatment of 15% BF + PP material for up to 5 times and the testing of its key mechanical properties, the results show that after 3 cycles, the comprehensive performance retention rate of the material is still higher than 78%. After five cycles, the performance retention rate remained stable within 77.8%. This study confirms that BF + PP recycled materials have outstanding performance stability and can meet the strict standards of mainstream Oems for the use of recycled materials. It provides reliable data support and solutions for the large-scale application of recycled materials in automotive parts, reducing the consumption of virgin materials and industrial waste.
