Waste shellfish shell stacking with a significant odor and toxicity which are hazardous to human constitutes a serious environmental hazard. For utilization of waste shellfish shell resource, granule of shellfish shell (SS) was prepared from waste shellfish shell by removing cuticle, crushing, grinding and shearing emulsification and was introduced as a filler to reinforce polypropylene (PP). The mechanical behavior of PP/SS composite shows a higher yield strain, yield strength, tensile strength and elongation at break than traditional commercial calcium carbonate (CC) filled PP. Yield strength of PP/SS composite with 2% SS is improved by 11.1% due to the formation of β-crystalline PP phase. Using waste SS for producing bio-filler for filling PP is an effective and prospective measure to deal with waste SS, which is valuable for industrial production and practical application as fillers for reinforcing polymers.
废弃贝类贝壳堆积物具有强烈的气味和毒性，对人体构成严重的环境危害。为了利用废弃贝类贝壳资源，通过去除外皮、粉碎、研磨和剪切乳化，将贝类贝壳颗粒（SS）从废弃贝类贝壳中制备出来，并作为一种填料来增强聚丙烯（PP）。PP/SS 复合材料的力学性能表现出更高的屈服应变、屈服强度、拉伸强度和断裂伸长率，优于传统的商业碳酸钙（CC）填充 PP。由于β-晶型 PP 相的形成，添加 2% SS 的 PP/SS 复合材料的屈服强度提高了 11.1%。利用废弃 SS 生产生物填料来填充 PP 是处理废弃 SS 的有效和有前景的措施，这对于工业生产和作为聚合物增强填料的实际应用具有重要价值。
