摘　　要：以二苯基甲烷二异氰酸酯(MDI)为改性剂对玻璃纤维表面进行改性,并通过真空导入的方式制备了玻璃钢。通过与硅烷偶联剂KH570进行对比,确认MDI作为改性剂的可行性。通过力学性能测试,结合扫描电子显微镜观察、能谱分析、傅里叶变换红外光谱分析对MDI改性玻璃纤维表面的机理进行了研究。结果表明:采用MDI改性的玻璃纤维制备的玻璃钢制品的层间剪切性能较采用未改性玻璃纤维提升了30%。Dibenyl methane diisocyanate(MDI)was used as modifier to modify the surface of glass fiber,and the glass fiber reinforced plastics was prepared by vacuum injection process.The feasibility of MDI as modifier was confirmed by comparing with silane coupling agent KH570.The mechanism of MDI modified glass fiber surface was studied by means of mechanical properties test,scanning electron microscope analysis,energy spectrum analysis and Fourier transform infrared spectroscopy analysis.The results show that the interlaminar sheer strength of glass fiber reinforced plastics prepared by MDI modified glass fiber is improved by 30%than that of unmodified ones.
