Mining full-length bolting-grouting agent and preparation method thereof
The invention discloses a mining full-length bolting-grouting agent and a preparation method thereof. A group of materials comprise, by mass, 40-50 parts of polyisocyanate, 10-20 parts of a reactive diluent, 1-3 parts of a surfactant, 10-20 parts of anhydrous calcium chloride, 20-30 parts of aggregate and 5 parts of a suspending agent; the material group B comprises the following components in parts by mass: 40-50 parts of an inorganic silicate solution, 12-22 parts of small molecular alcohol, 0.1-0.5 part of polymer rubber powder, 0.1 part of a catalyst, 2 parts of a suspending agent and 30-40 parts of aggregate; the volume ratio of the component A material to the component B material is 1: (0.5-1). The problems that an existing anchoring agent is inconvenient to use for full-length anchoring of an anchor rod or an anchor cable, the anchoring force is reduced when the anchoring agent encounters water, and diffusivity is poor are solved.
本发明公开了一种矿用全长锚注剂及其制备方法，其中：A组物料按质量份计为：多异氰酸脂40‑50份，活性稀释剂10‑20份，表面活性剂1‑3份，无水氯化钙10‑20份，骨料20‑30份，悬浮剂5份；B组物料按质量份计为：无机硅酸盐溶液40‑50份，小分子醇12‑22份，聚合物胶粉0.1‑0.5份，催化剂0.1份，悬浮剂2份，骨料30‑40份；A组份物料:B组份物料体积比为1:0.5‑1。本发明解决了现有的锚固剂不方便锚杆或锚索全长锚固使用、遇水锚固力下降及扩散性差的问题。
