Soft broken surrounding rock reinforcement grouting material and preparation method thereof
The invention provides a soft broken surrounding rock reinforcement grouting material and a preparation method thereof. The soft broken surrounding rock reinforcement grouting material comprises a component A and a component B, the component A contains foaming microcapsules and sulphoaluminate cement clinker, shells of the foaming microcapsules are methyl methacrylate hollow microspheres, and cores of the foaming microcapsules are foaming agents; the component B contains a mixture of an isocyanate microcapsule and limestone paste, the shell of the isocyanate microcapsule is methyl methacrylate hollow microspheres, and the core of the isocyanate microcapsule is isocyanate. The weak broken surrounding rock reinforcing grouting material is beneficial to enhancing the cohesiveness and filling and water plugging performance of the grouting material, and expansion foaming and active pressure grouting of a goaf can be achieved.
本发明提供了一种软弱破碎围岩加固注浆材料及其制备方法，该软弱破碎围岩加固注浆材料包括A组分和B组分；所述A组分含有发泡微胶囊和硫铝酸盐水泥熟料，所述发泡微胶囊的壳为甲基丙烯酸甲酯空心微珠，所述发泡微胶囊的核为发泡剂；所述B组分含有异氰酸酯微胶囊和石灰石膏混合物，所述异氰酸酯微胶囊的壳为甲基丙烯酸甲酯空心微珠，所述异氰酸酯微胶囊的核为异氰酸酯。本发明的软弱破碎围岩加固注浆材料有助于增强注浆材料的粘结性和充填堵水性能，可实现膨胀发泡，主动施压注浆采空区。
