Coalphilic quick-hardening double-liquid grouting material
The invention relates to the technical field of grouting materials, and discloses a coalphilic quick-hardening double-liquid grouting material which comprises slurry A and slurry B, wherein the volume ratio of the slurry A to the slurry B is (2-2.5): 1; the slurry A comprises a material A and water; the material A comprises slag, metakaolin, a water reducing agent, an expanding agent, redispersible latex powder and a suspending agent; the slurry B comprises a material B and water; and the material B comprises alkali metal hydroxide and silicate. According to the coalphilic quick-hardening double-liquid grouting material, the slurry A and the slurry B can react quickly after being mixed, the temperature in the reaction process is lower than 50 DEG C, and toxic and harmful gas is not generated when the slurry A and the slurry B react; the grouting material is mainly used for coal mining and can replace chemical grouting materials to reinforce coal walls; and the coal wall reinforcing effect is good, the reinforced coal wall is complete and hard, and the problem of wall caving of the coal wall can be well solved.
本发明涉及注浆材料技术领域，公开了一种亲煤快硬双液注浆材料，所述亲煤快硬双液注浆材料包括A液浆、B液浆；A液浆与B液浆的体积比为2‑2.5:1；所述A液浆包括A料、水；所述A料包括矿渣、偏高岭土、减水剂、膨胀剂、可再分散乳胶粉、悬浮剂；所述B液浆包括B料、水；所述B料包括碱金属氢氧化物、硅酸盐。本发明的亲煤快硬双液注浆材料，A液浆与B液浆混合后能够快速反应，反应过程中温度低于50℃，且A液浆与B液浆反应时不产生有毒有害气体；主要用于煤矿开采，可代替化学注浆材料加固煤墙；煤墙加固效果好，加固的煤墙完整、坚硬，能很好的解决煤墙片帮的问题。
