| 研究了含磷阻燃型离子液体（［TCEPMIM］［Cl］）对煤矿用聚氨酯注浆材料结构与性能的影响，重点考察了［TCEPMIM］［Cl］对其导热和热稳定性能的影响.结果表明：［TCEPMIM］［Cl］在聚氨酯注浆材料的固化过程中，会影响其结构形成；当［TCEPMIM］［Cl］掺量（质量分数）从0%增加到20%时，聚氨酯注浆材料的导热系数逐渐增大，最大值为0062W/(m·K)；聚氨酯注浆材料的热稳定性能则随［TCEPMIM］［Cl］掺量的增加呈现先提高后降低的变化趋势；当［TCEPMIM］［Cl］的掺量为2%时，聚氨酯注浆材料的起始分解温度和最大分解速率温度达到最大值，分别为3003，3432℃；当［TCEPMIM］［Cl］的掺量为5%时，聚氨酯注浆材料热分解后残留质量分数最大（280%）；通过比较发现，当［TCEPMIM］［Cl］掺量为5%时，聚氨酯注浆材料的综合性能最佳，在呈现较好抗静电性能和抗压强度的同时，还具有一定的阻燃能力、较高的导热系数和热稳定性. |

| Abstract: |
| The impacts of ［TCEPMIM］［Cl］, one kinds of ionic liquid containing phosphonium, on the structure and properties of polyurethane grouting materials(PUGM) applied in coal mine were investigated, especially the effects of ［TCEPMIM］［Cl］ on their thermal conductivity and thermal stability. The results reveal that ［TCEPMIM］［Cl］ has obvious effects on the structure formation and properties of PUGM. When the addition amount of ［TCEPMIM］［Cl］ changes from 0%(by mass) to 20%, the thermal conductivity of PUGM increases to 0062 W/(m·K). Additionally, the thermal stability of PUGM increases at first and then decreases with gradually increasing amount of ［TCEPMIM］［Cl］ in PUGM. When the amount of ［TCEPMIM］［Cl］ is 2%, the PUGM presents the highest initial decomposition temperature and the maximum decomposition rate temperature will be at 3003℃ and 3432℃ respectively. The maximum residual mass of decomposed PUGM is 28% when the amount of ［TCEPMIM］［Cl］ is 5%. The PUGM exhibits a higher compressive strength, better antistatic property, excellent thermal conductivity and thermal stability, and then it also has a good flame retardant ability when the added amount of ［TCEPMIM］［Cl］ is 5% in its matrices. |
