Flexible solid-waste-based lightweight expansion cementing material for mine leakage stoppage and preparation and use methods thereof
The invention discloses a flexible solid waste based light expansion cementing material for mine plugging and preparation and use methods, the flexible solid waste based light expansion cementing material is prepared by uniformly mixing composite slurry and a foam system according to a volume ratio of 1: 1.8-2.2, and the composite slurry comprises the following components: an industrial solid waste material, cement, waste rubber powder, elastic fiber and an alkaline activator. The water cement ratio is 0.45 to 0.5; the foam system is prepared by mixing an anionic surfactant, a zwitterionic surfactant, a foam stabilizer and water and carrying out physical foaming. The material is doped with a large amount of industrial solid waste, has excellent heat insulation and heat resistance effects, effective sealing and leaking stoppage effects and remarkable energy absorption and shock absorption characteristics, has good bonding and reinforcing effects on loose coal bodies and the like, can effectively reduce spontaneous combustion fire risks and inhibit diffusion of toxic and harmful gases, and is energy-saving and environment-friendly.
本发明公开了一种用于矿井堵漏的柔性固废基轻质膨胀胶凝材料及制备与使用方法，由复合浆体和泡沫体系按照体积比为1：1.8～2.2均匀混合制成，其中所述复合浆体由以下组分组成：工业固体废弃物材料、水泥、废弃橡胶粉、弹性纤维、碱性激发剂，0.45～0.5的水灰比；所述泡沫体系由阴离子表面活性剂、两性离子表面活性剂、稳泡剂和水混合，经物理发泡制成。本发明的材料掺入大量工业固体废弃物，具备优异的隔热耐热效果、有效的密闭堵漏作用及显著的吸能减震特征，且对松散煤体具有良好的黏结加固效果等，能够有效减小自燃火灾风险、抑制有毒有害气体的扩散，节能环保。
