摘　　要：为解决采空区内液体阻化剂易从岩石缝流失的问题,通过正交试验、对比试验及热重分析,研究新型液体阻化泡沫的发泡性能和阻化性能.结果表明:当AES、MPS、CMC、MgCl_2质量分数分别为0.5%、0.2%、0.1%、5%时,阻化泡沫综合性能最佳.随着AES或CMC质量分数增大,发泡倍数先增加后减小,泡沫稳定性和保水性降低;随着MPS质量分数增大,发泡倍数降低,析液半衰期和保水性先增加后减小;随着MgCl_2质量分数增加,发泡倍数和析液半衰期先增大后减小,保水性增强;阻化泡沫的阻化效果较好.In order to solve the problem of liquid retarder wastage from cracks in the goaf, foaming properties and inhibition performance of a new type of liquid paralysor foam are researched by orthogonal experiment, comparative trial and TGA. The results show that when mass fractions of AES、MPS、CMC、MgCl2 are 0.5%, 0.2%, 0.1% and 5% respectively, comprehensive properties of inhibition foam is the best. Expansion ratios climbs up and then declines with the increasing content of AES or CMC or MgCl2. Foam stability and water retention are reduced with the increasing content of AES or CMC. Fluid half-lives climbs up and then declines with the increasing content of MPS or MgCl2. Expansion ratio declines with the increasing content of MPS. Water retention is enhanced with the increasing content of MgCl2. The effect of inhibitor of retarder is well.
