摘要

采用固相力化学技术制备废旧电路板非金属材料(WPCB)改性粉体

填充废弃聚丙烯(PP)

制备了高性能废旧PP/WPCB复合材料

研究了固相剪切对WPCB粒度、粒度分布以及PP/WPCB复合材料结构、流变性能和力学性能的影响。结果表明

磨盘碾磨使WPCB粉体体积粒径由282.4μm降到63.5μm

比表面积由0.06m

/g提高到0.14m

粒度分布明显变窄

玻纤与环氧树脂剥离效果明显。固相力化学方法制备WPCB粉体填充废旧PP后

其分散大幅改善

加工性能明显优于未碾磨体系

复合材料力学性能优于纯PP和未经固相力化学处理的PP/WPCB复合材料

相对于纯PP拉伸强度提高14.6%

弯曲模量提高82.5%

缺口冲击强度提高11.2%。得到的材料表面色泽均一、成本低廉

具有良好工业化前景。

Abstract

In this article

pan milled wasted printed circuit boards (WPCB) powder and polypropylene (PP)/Waste Printed Circuit Boards (WPCB) composite with high performance were prepared by Solid State Shear Milling (S

M). The particles size and distribution of WPCB powder

dispersion

rheology and mechanical properties of the composite were further investigated. The results showed that the average particle size and surface area of WPCB powder dropped from 282.4um to 63.5um and 0.06m

/g to 0.14m

/g respectively. Meanwhile

the particles size distribution become narrow and the epoxy resin exfoliated from fiberglass obviously. After pan milled the dispersion of WPCB and the processibility of composite is significantly improved. The mechanical test result showed that the mechanical properties of PP/WPCB composites which prepared by S

M was superior to pure PP. The maximum increment of tensile strength

flexural modulus and the heated-distortion temperature is 14.6%

82.5% respectively. The composite obtained has a good surface color

low cost and a very broad prospect for industrialization.
