Waterproof anchoring agent for water-containing soft rock and preparation method thereof
The invention relates to the technical field of anchoring agents, in particular to a waterproof anchoring agent for water-containing soft rock and a preparation method thereof.The waterproof anchoring agent comprises a component A and a component B. The component A comprises resin mortar, an accelerant and a coupling agent, and the resin mortar comprises modified unsaturated polyester resin, calcium carbonate, dolomite and mica powder; the modified unsaturated polyester resin comprises palmitoleic acid monoglyceride and conjugated trienylpyridine; the component B comprises benzoyl peroxide, chlorobenzene, biphenyl and polyether polyol, and the polyether polyol is prepared by introducing bisphenol A into epoxypropane and carrying out ring opening polymerization; according to the prepared waterproof anchoring agent, the problems that an anchor cable body and a traditional resin anchoring agent are low in bonding rigidity in argillization roadway surrounding rock and prone to sliding deformation, high pre-tightening force cannot be applied, the utilization rate of an anchor cable is low, and deformation of the roadway surrounding rock cannot be efficiently controlled through the anchor cable are solved; the waterproof anchoring agent can be used for efficiently anchoring an anchor cable in argillization roadway surrounding rock.
本发明涉及锚固剂技术领域，尤其涉及一种用于含水软岩的防水锚固剂及其制备方法，防水锚固剂包括A组分和B组分，A组份包括树脂胶泥、促进剂、偶联剂，树脂胶泥包括改性不饱和聚酯树脂、碳酸钙、白云石和云母粉，改性不饱和聚酯树脂包括棕榈油酸单甘脂和共轭三烯吡啶；B组份包括过氧苯甲酰、氯化苯、联苯和聚醚多元醇，聚醚多元醇是在环氧丙烷中引入双酚A进行开环聚合制得；本发明制备的防水锚固剂，克服了锚索索体与传统树脂锚固剂在泥化巷道巷道围岩中粘结刚度低容易滑动变形而无法施加高预紧力、锚索利用率低、无法实现锚索高效控制巷道围岩变形的问题，该防水锚固剂可用于锚索在泥化巷道围岩中高效锚固。
