Chemical expansion anchoring agent capable of being used for surrounding rock of soft rock roadway and preparation method of chemical expansion anchoring agent
The invention relates to the technical field of anchoring agents, in particular to a chemical expansion anchoring agent capable of being used for surrounding rock of a soft rock roadway and a preparation method of the chemical expansion anchoring agent. The resin mud glue comprises low-curing unsaturated polyester resin, a low-shrinkage additive, a filler, an accelerant and an expanding agent; the curing agent comprises benzoyl peroxide, chlorobenzene, biphenyl and benzene. The low-curing unsaturated polyester resin contains styrene derivatives, and introduced polymer microgel can improve the compressive strength; the low-shrinkage additive is prepared by modifying and coating calcium sulfate whiskers with sodium oleate, and double bonds are introduced to the surface of the low-shrinkage additive, so that the shrinkage rate is reduced. The prepared chemical expansion anchoring agent for the surrounding rock of the soft rock roadway can be well combined with an anchor rod cable into a whole in a soft broken surrounding rock drill hole, stable anchoring of the anchor rod cable in the soft broken surrounding rock is achieved, and strong technical support is provided for supporting of the surrounding rock of the soft rock roadway.
本发明涉及锚固剂技术领域，尤其涉及一种可用于软岩巷道围岩的化学膨胀锚固剂及其制备方法，化学膨胀锚固剂包括树脂泥胶和固化剂；树脂泥胶包括低固化不饱和聚酯树脂、低收缩添加剂、填料、促进剂、膨胀剂；固化剂包括过氧苯甲酰、氯化苯、联苯和苯。低固化不饱和聚酯树脂中含有苯乙烯衍生物，引入的聚合物微凝胶可以提高抗压强度；低收缩添加剂用油酸钠改性包覆硫酸钙晶须制得，在低收缩添加剂表面引入双键，从而降低收缩率。本发明制备的可用于软岩巷道围岩的化学膨胀锚固剂，可以很好的在软弱破碎围岩钻孔中与锚杆索结合为一个整体，实现锚杆索在软弱破碎围岩中稳定锚固，为软岩巷道围岩支护提供强力技术支撑。
