Background
In the coal mining process, along with the increase of the mining depth, underground rib caving and roof caving accidents frequently occur. The polyurethane material is widely applied to reinforcement of underground coal rock mass due to the advantages of low viscosity, good permeability, controllable curing time, corrosion resistance, wear resistance and the like. The silicate modified polyurethane reinforcing material is one of polyurethane modified materials, and compared with the traditional polyurethane reinforcing material, the silicate modified polyurethane reinforcing material has the advantages that the material cost is greatly reduced due to the addition of the sodium silicate with lower price, and the silicate modified polyurethane reinforcing material has higher commercial value. But the raw materials for producing the silicate modified polyurethane have high viscosity, the formula has high requirement on the mixing uniformity of materials, and the components cannot be fully and uniformly mixed in a kettle; and because the stirring is insufficient, part of materials can not react, so that the pollution of each component is more easily caused.

Further, the length of the third stirring blade is greater than that of the fourth stirring blade.
Furthermore, a plurality of via holes are uniformly arranged on the central axis of the anchor type blade.
Further, the included angle between the triangular blade and the first stirring blade or the second stirring blade is 60 degrees.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, four stirring blades with different structures are arranged on the stirring shaft, anchor type slurry adding stirring is adopted, and the first and second stirring blades with the slurry structures are additionally provided with the triangular blades with certain angles, so that multi-angle cutting can be formed together with the stirring blades, a multi-directional shearing effect is formed in the stirring process, and the influence of component viscosity on stirring is reduced. The anchor type blade is additionally provided with the through hole, so that the resistance of the stirring blade with relatively large viscosity at the bottom is reduced, the stirring efficiency is improved, and the stirring process is more sufficient under the same stirring time and power.
The structure of the utility model effectively reduces the influence of the viscosity of the components on the stirring process, so that the silicate modified polyurethane reinforcing material is more complete and thorough in the stirring reaction process of production, and the quality of the product is improved.
