preparation example Construction

[0054] A preparation method for mine full-length anchor grouting agent, comprising the following steps:

[0055] ⑴Preparation of component A material: Take it at room temperature, put polyphenyl polymethylene polyisocyanate, reactive diluent, surfactant and suspending agent into the reaction kettle and stir thoroughly; then anhydrous chlorinated Calcium and aggregate are added into the reaction kettle and stirred evenly to obtain component A material, and the component A material is packaged into a cylindrical plastic bottle.

[0056] ⑵Preparation of component B materials: at room temperature, add small molecule alcohol and catalyst into the reactor and stir evenly; add inorganic silicate solution, polymer rubber powder, and suspending agent into the reactor and stir evenly, then put Add it into the reaction kettle and stir well to make the sediment completely suspended, that is, to obtain the B component material, and pack the B component material into a cylindrical plastic b...

Embodiment 1

[0070] (1) Preparation of component A materials: take 40 kg of polyphenyl polymethylene polyisocyanate, 10 kg of reactive diluent, 1 kg of surfactant, 10 kg of anhydrous calcium chloride, 20 kg of aggregate, suspending agent 5 kg. At normal temperature, put polyphenyl polymethylene polyisocyanate, reactive diluent, surfactant and suspending agent into the reactor and stir well; then add anhydrous calcium chloride and aggregate into the reactor Stir evenly to obtain the component A material, and pack the component A material into a cylindrical plastic bottle.

[0071] (2) Preparation of component B materials: Take 40 kg of inorganic silicate solution, 12 kg of small molecule alcohol, 0.1 kg of polymer rubber powder, 0.1 kg of catalyst, 2 kg of suspending agent, and 30 kg of aggregate. At normal temperature, add the small molecule alcohol and catalyst into the reactor and stir evenly; add the inorganic silicate solution, polymer rubber powder, and suspending agent into the reac...

Embodiment 2

[0080] (1) Preparation of component A materials: Take 45 kg of polyphenyl polymethylene polyisocyanate, 15 kg of reactive diluent, 2 kg of surfactant, 15 kg of anhydrous calcium chloride, 25 kg of aggregate, suspending agent 5 kg. At normal temperature, put polyphenyl polymethylene polyisocyanate, reactive diluent, surfactant, and suspending agent into the reactor and stir fully; then add the aggregate into the reactor and stir evenly to obtain Component A material, package the component A material into a cylindrical plastic bottle.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of grouting materials in mine support, in particular to a mine-used full-length anchor grouting agent and a preparation method thereof. Background technique [0002] Now in many mines, tunnels, slopes and other constructions, anchor rods and anchor cables are used to support the rock mass. Insert the anchoring agent into the borehole and send the anchoring agent to the bottom of the drilling hole, use the bolter to drive the anchor rod or the anchor cable body to rotate and stir the anchoring agent to make the end of the anchor rod or anchor cable take root in the rock, so that the anchor rod and anchor cable can Supporting the surrounding rock, due to the technical limitations of the existing drug coil anchoring agent, it is difficult to carry out full-length anchoring construction on the anchor rod or anchor cable. The anchoring agent cannot fill the borehole and can only end the anchor rod or anchor cable...
