摘要

以3-氨基丙基三乙氧基硅烷(KH-550)为改性剂

在导向管喷动流化床内对废弃印刷线路板的非金属颗粒(NPWPCB)进行包覆改性

研究了颗粒包覆过程中KH-550溶液(体积分数20%)用量、喷雾速率、雾化气速、床层温度及喷动气速等操作参数对NPWPCB改性效果的影响。以聚丙烯(PP)为基体、改性NPWPCB为填料

采用挤出注塑工艺制备了PP/NPWPCB复合材料。通过红外光谱图和扫描电子显微镜对改性前后NPWPCB表面官能团及复合材料冲击断面微观形貌的分析表明

KH-550可以增加NPWPCB与PP基体之间的界面黏结强度

提高PP/NPWPCB复合材料的力学性能。当KH-550溶液用量为75 ml、喷雾速率为3.2 cm·s-1、雾化气速为58.98 m·s-1、床层温度为80℃、喷动气速为29.49 m·s-1时

复合材料的弯曲、拉伸和冲击强度较改性前分别提高了15.07%、17.52%和16.32%。

Abstract

Non-metal particles of waste printed circuit boards (NPWPCB) were modified with 3-aminopropyltriethoxysilane (KH-550) by coating in a spout-fluid bed with draft tube. To obtain the range of operating parameters for the modification

the effects of KH-550 solution (20%(vol)) volume

spray rate

atomizing gas velocity

bed temperature

and spouting gas velocity on modification were evaluated. The modified NPWPCB were used as filler to fabricate PP/NPWPCB composites by extrusion and injection molding. The variations of the surface functional groups and the cross-section morphology were characterized by infrared spectroscopy and scanning electron microscopy. Modified NPWPCB improved the interface bonding between NPWPCB and PP

which enhanced the mechanical properties of PP/NPWPCB composites. At KH-550 solution (20%(vol)) volume of 75 ml

spray rate of 3.2 cm·s-1

atomizing gas velocity of 58.98 m·s-1

bed temperature of 80℃

and spouting gas velocity of 29.49 m·s-1

flexural strength

tensile strength

and impact strength of the composites increased by 15.07%

17.52% and 16.32%

respectively.
