煤矿井下化学注浆与注浆材料与煤体之间的相互作用密切相关。本文采用室温固化工艺，研制了一种高性能、低成本的新型煤基胶粘剂--水玻璃/聚氨酯胶粘剂。为了更直观、全面地了解煤表面的粘结作用，采用石英晶体微天平（QCM）和傅里叶变换红外光谱（FTIR）技术研究了水玻璃/聚氨酯胶粘剂在煤表面的粘结过程。结果表明，pMDI中的NCO基团与煤表面的OH基团之间的相互作用是主要的键合力。力学性能测试表明，煤/胶粘剂复合物的抗压强度和抗折强度分别达到21.4和5.8MPa。
Chemical grouting in underground coal mines is related closely to the interaction between grouting materials and coal. In the present work, a novel adhesive with high properties and low cost, waterglass/polyurethane, has been developed for coal bonding, based on a room-temperature-curing process. To obtain a direct and comprehensive understanding of the adhesive interaction at the surface of coal, quartz crystal microbalance (QCM) and Fourier-transform infrared spectroscopy (FTIR) techniques were employed to investigate the bonding process of waterglass/polyurethane adhesive on coal coating. The obtained information suggests that the interaction between the NCO groups in pMDI and the OH groups at the surface of coal is the dominant bonding force. The mechanical tests indicate that the compressive and flexural strength of the coal/adhesive composition can reach 21.4 and 5.8 MPa, respectively.
