Grouting material for reinforcement and preparation method thereof
The invention discloses a grouting material for reinforcement. The grouting material is composed of a component A and a component B, the component A comprises isocyanate, a diluent, an emulsifier and superfine three-dimensional silver-zinc superfine powder; the component B comprises water glass, polypropylene short fibers and superfine three-dimensional silver-zinc superfine powder; the volume ratio of the component A to the component B is 1: 1. The grouting material provided by the invention can effectively reduce oil-water interfacial tension, has significantly improved tensile strength, compressive strength, bonding strength and other mechanical properties, has good antibacterial and antistatic capabilities, can be well used in reinforcement operations of coal mine rock masses, tunnel rock masses, hydropower stations and the like, ensures the strength of coal mine deposits and roofs, and has good application prospects. Accidents such as roof falling, roof falling and collapse of a coal mine are avoided or greatly reduced, the safety degree of coal mine operation can be effectively improved, and the coal mining process can be safely and smoothly implemented; in addition, the grouting material provided by the invention is excellent in performance of a consolidated body, easy to operate and beneficial to large-scale use.
本发明公开了一种用于加固的注浆材料，由A组分和B组分构成；A组分为异氰酸酯、稀释剂、乳化剂、超细立体银锌超细粉末；B组分为水玻璃、聚丙烯短纤维、超细立体银锌超细粉末；A组分与B组分的体积比1：1。本发明提供的注浆材料能够有效降低油水界面张力，且其抗拉强度、抗压强度、粘接强度等力学性能均有显著提高，而且具有良好的抗菌和抗静电能力，能够较好用于煤矿岩体、隧道岩体、水电站等的加固作业中，保障煤矿矿床及顶板强度，避免或极大程度降低煤矿发生顶板脱落、冒顶、坍塌等事故，能够有效提高煤矿作业安全程度，使得煤矿开采过程能够安全顺利实施；另外本发明提供的注浆材料其固结体性能优异，操作容易完成，有利于大规模使用。
