ABSTRACT

In this study, the composite materials based on high density polyethylene (HDPE) and yellow phosphorus slag (YPS, by-product of yellow phosphorus production) were prepared using melt blending method in a Haake intermixer. Some kinds of YPS particles with different size were used as additives for the composites, in which, the YPS particles having size lower than 10 µm (L4 particle sample) were the most suitable additive for the composites based on HDPE. Thanks to the good dispersion of L4 particles in HDPE matrix, properties of HDPE/L4 composites such as mechanical, electrical and thermal properties, as well as flame resistance of HDPE/L4 composites were significantly improved. The HDPEL4 composite containing 5 wt.% of L4 particles had high tensile strength and elongation at break, regular structure, high thermal stability and good fire resistance. It is promising for the applications in technical fields.

摘要

在这项研究中，采用熔体共混法在 Haake 混合机中制备了基于高密度聚乙烯 (HDPE) 和黄磷渣（YPS，黄磷生产的副产品）的复合材料。一些不同尺寸的 YPS 颗粒被用作复合材料的添加剂，其中尺寸小于 10 µm 的 YPS 颗粒（L4 颗粒样品）是最适合基于 HDPE 的复合材料的添加剂。由于L4颗粒在HDPE基体中的良好分散性，HDPE/L4复合材料的力学、电学、热学等性能以及HDPE/L4复合材料的阻燃性能得到显着提高。含有5 wt.% L4颗粒的HDPEL4复合材料具有较高的拉伸强度和断裂伸长率、规则的结构、较高的热稳定性和良好的耐火性。
