Abstract

The invention relates to a resin anchoring agent realizing rapid loading under water. The resin anchoring agent is prepared by mixing epoxy resin cement gum and an organic amine curing agent according to a mass ratio of (2-4):1. By adopting the resin anchoring agent prepared in the invention, rapid curing can be implemented in an underwater environment during specific construction, and anchor rods, anchor ropes and the like can be firmly adhered in anchor eyes to bear enough load so as to achieve a good bottom swelling treatment effect and to provide a reliable anchoring material for rapid construction of a high-pretightening force grouting anchor rope.

Description

technical field [0001] The invention relates to an underwater quick-loading resin anchoring agent and a preparation method thereof, which belong to the treatment project of coal mine roadway bottom. Background technique [0002] Reinforcement of roadway surrounding rock with anchor rods and anchor cables combined with resin anchoring agent is the main method of coal mine roadway support at present. The resin anchoring agent used is basically unsaturated polyester resin as bonding material and stone powder as filler. , with peroxide as the curing agent, together with accelerators, thixotropic agents, thickeners and other additives, packed in double-hole film bags. Due to the poor water resistance of unsaturated polyester resin, it cannot provide effective anchoring force when anchoring in water-bearing formations, especially underwater. [0003] Chinese invention patent CN101041745A discloses a method for preparing a water-resistant resin anchoring agent. By changing the fun...
