摘要/Abstract

摘要： 以废弃贻贝壳为原料, 经去除角质层、粉碎、研磨、剪切乳化得到生物填料, 然后对聚丙烯(PP)进行充填. 研究分析了生物填料的物相组成、微观形貌、热稳定性和对其PP充填力学性能的影响. 实验结果表明, 制备的生物填料主要成分为文石碳酸钙, 成片状, 粒径大小约为40~500 nm, 有机物含量约为2.04wt%, 热稳定性良好. 生物填料(YBCC)对PP具有增强效果. 当填充比例为3wt%时, PP/(YBCC)复合材料屈服强度比PP提高了约11.1%; 对PP亦具有异相成核的作用, 可诱导形成?晶. 利用废弃物贻贝壳为原料生产的生物填料填充PP可降低材料成本, 提高力学性能和结晶性能, 具有广阔的应用前景.

Abstract: Waste mussel shell stacking with a significant odor and toxicity which are hazardous to human constitutes a serious environmental hazard. For utilization of waste mussel shell resource, granule of mussel shell (YBCC) was prepared from waste mussel shell by removing cuticle, crushing, grinding and shearing emulsification and was introduced as a filler to reinforce polypropylene (PP). The characterization results of YBCC show that the mainly composition of YBCC is aragonite (CaCO₃) platelets and the particle size distribution range of YBCC powder is from 40 nm to 500 nm, the proportion of organic components of YBCC is about 2.04wt% and YBCC has a good thermal stability. The mechanical behavior of PP/YBCC composite shows a higher yield strain, yield strength, tensile strength and elongation at break than traditional commercial calcium carbonate (CMCC) filled PP. Yield strength of PP/YBCC composite with 3wt% YBCC is improved by about 11.1%. A small content (about 1wt%) of YBCC can promote the heterogeneous nucleation for PP crystallization and the formation β-crystalline PP. Using mussel shell for producing bio-filler is valuable for industrial production and practical application as fillers for reinforcing polymers.
