中文摘要：

为研究马来酸酐接枝聚乙烯（MAPE）、异丙基三（硬脂酰基）钛酸酯（YB-510）、γ-（2,3-环氧丙氧）丙基三甲氧基硅烷（KH-560）3种偶联剂对稀土荧光竹塑复合材料发光性能、力学性能和热稳定性的影响,利用荧光分光光度计、电子万能试验机、摆锤冲击仪和热重分析仪对复合材料的荧光性能、力学性能和热稳定性进行了表征,并利用场发射扫描电子显微镜（FESEM）对稀土荧光竹塑复合材料的拉伸断面的微观形貌进行观察。结果表明,3种偶联剂都能改善稀土荧光竹塑复合材料的分散性、流动性、发光性能、弯曲强度、弯曲模量、拉伸强度和冲击强度;场发射扫描电镜显示,铝酸锶荧光粉在有偶联剂添加的稀土荧光竹塑复合材料的基体中分散均匀、团聚减少、界面黏合作用改善;相比于钛酸酯（YB-510）和KH-560,MAPE对稀土荧光竹塑复合材料的发光性能、力学性能和分散性提高更明显;热失重（TG）曲线和一阶微分（DTG）曲线分析表明,KH-560提高稀土荧光竹塑复合材料的热稳定性,钛酸酯（YB-510）对稀土荧光竹塑复合材料的热稳定性产生不良影响,MAPE对稀土荧光竹塑复合材料的热稳定性的影响不明显。

英文摘要：

In order to investigate the effects of three coupling agents（MAPE, YB-510, KH-560） on the luminescence property, the mechanical property and the thermal stability of the rare earth fluorescent bamboo plastic composites, the fluorescence spectrophotometer,the electronic universal testing machine, the pendulum impact tester and the thermogravimetric analyzer are employed, in addition, the tensile fracture microstructures of the rare earth fluorescent bamboo plastic composites are observed by the field emission scanning electron microscopy（FESEM）. The results show that the three coupling agents can improve the dispersion, the fluidity, the luminescence property,the bending strength, the bending modulus, the tensile strength and the impact strength of the rare earth fluorescent bamboo plastic composites. The scanning electron microscopy shows that the dispersibility and the interface bonding of the strontium aluminate phosphor are improved in the composites by using the coupling agent, the birdnesting is decreased too. The MAPE is better in improving the properties of the rare earth fluorescent bamboo plastic composites than the YB-510 and the KH-560. The thermogravimetric（TG） and derivative thermogravimetric（DTG） curves of the rare earth fluorescent bamboo plastic composites indicate that the KH-560 is better to improve the thermal stability of the rare earth fluorescent bamboo plastic composites, the YB-510 has an adverse effect on the thermal stability of the composites, and the MAPE has no effect on the thermal stability of the composites.
