Abstract

Xuan-paper waste residue (XPWR) is an unfamiliar and unique solid waste in China, which caused serious environmental pollution and waste of resources. Therefore, it is extremely important to explore the characteristics of XPWR and its application. In this paper, XPWR was analyzed and used as a reinforcing filler to prepare red mud/waste polyethylene/Xuan-paper waste residue (RM/WPE/XPWR) composites by molding method at 160 °C with a pressure of 10 MPa for 5-10 min. There were about 27 wt% of mineral particles and 63 wt% of organic fibers in XPWR, indicating that XPWR can be used as a reinforcing filler. When 60 wt% of XPWR was added in RM/WPE, the bending strength reached 71.81 MPa, which surpassed 43.08 % than that of RM/WPE. Besides, the addition of XPWR increased the water absorption of the composites and helped to promote the crystallization of the composites. This work presented the characteristics of XPWR and provided a new way to use XPWR.

摘要

萱纸废渣（XPWR）是中国一种陌生而独特的固体废物，它造成了严重的环境污染和资源浪费。因此，探索 XPWR 的特性及其应用极为重要。本文分析了 XPWR，并将其作为增强填料，通过模压法在 160°C 下以 10 MPa 的压力成型 5-10 分钟，制备了赤泥/废聚乙烯/萱纸废渣（RM/WPE/XPWR）复合材料。XPWR 中约有 27wt%的矿物质颗粒和 63wt%的有机纤维，表明 XPWR 可以用作增强填料。当 RM/WPE 中添加 60wt%的 XPWR 时，弯曲强度达到 71.81MPa，比 RM/WPE 提高了 43.08%。此外，XPWR 的添加增加了复合材料的吸水性，并有助于促进复合材料的结晶。本工作介绍了 XPWR 的特性，并为 XPWR 的利用提供了新途径。
