Waterproof anchoring agent as well as preparation method, application and performance evaluation method thereof
The invention relates to the technical field of anchoring, and discloses a waterproof anchoring agent as well as a preparation method and application thereof and a performance evaluation method. The waterproof anchoring agent comprises unsaturated polyester resin, silicate, a silane coupling agent, a reactive diluent, a curing agent, an accelerant and instant glue powder. The waterproof resin anchoring agent is prepared by adjusting the raw materials, isocyanate is used as a curing agent, high-energy particles (silicate) are used as filler, the waterproof resin anchoring agent with high strength, high activity and good water resistance is prepared, and the waterproof resin anchoring agent has the excellent performance of ultrafast water absorption, fast solidification and high strength; meanwhile, a new evaluation method is provided on the basis of related requirements of MT146.1-2011 and used for detecting the mechanical property of the waterproof anchoring agent, the waterproof capacity of the anchoring agent is verified through a specially-designed anchoring pull-out test, and compared with a common resin anchoring agent, the applicability of the waterproof anchoring agent under the working condition of the shallow-buried water-rich stratum is determined.
本申请涉及锚固技术领域，公开了一种防水锚固剂及其制备方法和应用及性能评价方法。本申请所述防水锚固剂包括不饱和聚酯树脂、硅酸盐、硅烷偶联剂、活性稀释剂、固化剂、促进剂和速溶胶粉。本申请通过调整原料制作防水树脂锚固剂，以异氰酸酯作为固化剂，以高能粒子(硅酸盐)作为填料，制备出高强度、高活性和耐水性好的防水型树脂锚固剂，具有超快吸水、快速凝固、强度高的优异性能；同时在MT146.1‑2011相关要求的基础上提供了一种新的评价方法，用以检测防水锚固剂的力学性能，通过特殊设计的锚固拉拔试验验证锚固剂的防水能力，并与普通树脂锚固剂对比，确定了防水锚固剂能在浅埋富水地层工况下的适用性。
