Inorganic grouting material based on in-situ polymerization modification, preparation method and application thereof
The embodiment of the invention provides an inorganic grouting material based on in-situ polymerization modification and a preparation method and application of the inorganic grouting material. The inorganic grouting material comprises a material A and a material B. The material A comprises an active mixture, after polymerization of active mixtures such as N-isopropylacrylamide, methylene bisacrylamide, methylene bisacrylamide, methylene bisacrylamide and the like in the active mixtures is completed, multiple amido bonds are formed; after the material A and the material B are mixed, N-isopropylacrylamide, methylene bisacrylamide, methylene bisacrylamide and methylene bisacrylamide are subjected to in-situ polymerization to form copolymer macromolecules, the copolymer macromolecules have an amphiphilic structure, and slurry formed by the inorganic grouting material is rapidly solidified, so that slurry leakage is avoided, and the problem of serious slurry leakage of loose and broken coal mine tunnels is solved.
本申请实施例提出了一种基于原位聚合改性的无机注浆材料、制备方法及其应用，无机注浆材料包括A料和B料，A料中包括活性混合体，活性混合体中N‑异丙基丙烯酰胺、亚甲基双丙烯酰胺、甲撑双丙烯酰胺、次甲基双丙烯酰胺等活性混合体聚合完成后，形成多重酰胺键；当A料和B料混合后，N‑异丙基丙烯酰胺、亚甲基双丙烯酰胺、甲撑双丙烯酰胺、次甲基双丙烯酰胺原位聚合形成共聚物大分子，具有两亲性结构，且无机注浆材料形成的浆液迅速凝固，避免漏浆，解决松散破碎煤矿巷道漏浆严重的问题。
