[0002] The application of water-based anti-corrosion coatings in infrastructure, oil and gas, and power industries has been increasing year by year. Applications have shown that water-based industrial anti-corrosion coatings can provide some protection for steel under extreme conditions. Graphene, with its unique nanostructure and excellent physical properties, combined with its large specific surface area, good compatibility, and abundant surface hydroxyl groups, is being introduced into a growing number of fields. Adding graphene as a modifier to coatings can compensate for the shortcomings of fillers and resins, effectively preventing corrosion.

[0003] However, during the mixing stage of existing coatings, the stirring structure is mostly a motor-driven stirring blade that stirs the materials back and forth, and the stirring form is relatively simple. For example, when a variety of different materials are added to a solvent (water) for dissolution, large flocs or "fish eyes" often appear, seriously affecting the use effect of graphene-modified waterborne polyurethane-epoxy resin coatings.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 2As shown, the utility model provides a stirring device, comprising a reaction barrel 1, a motor 2 installed on one side of a feeding port 10 of the reaction barrel 1, and a stirring assembly located in the reaction barrel 1 and driven to rotate by the motor 2, the stirring assembly comprising a fixed rod 3, a spiral plate 4 and a plurality of crushing rods 5, one end of the fixed rod 3 is connected to the output shaft of the motor 2 by a coupling, and the other end of the fixed rod 3 extends to the bottom side of the inner wall of the reaction barrel 1; the spiral plate 4 is sleeved on the outer peripheral side of the fixed rod 3, and the two ends of the spiral plate 4 respectively extend spirally along the axial direction of the fixed rod 3 to the upper and lower sides of the inner wall near the reaction barrel 1; the plurality of crushing rods 5 are respectively obliquely installed between the spiral plate 4 and the fixed rod 3, and the plurality of crushing rods 5 are arranged side by side along the axial direction of the fixed rod 3, so as to form a vortex in the reaction barrel 1 when the motor 2 drives the stirring assembly to stir the material, and the crushing rods 5 are used to crush the material in the vortex, thereby avoiding the occurrence of large flocs or "fisheye" phenomenon in the material during the dissolution process, so as to improve the use effect of the graphene modified waterborne polyurethane-epoxy resin coating.

[0021] In this embodiment, in order to improve the turbulent effect of the breaker bar 5, the breaker bar 5 can be designed as a strip plate structure; at the same time, in order to improve the breaker bar 5's crushing effect on large flocs or "fish eyes", spurs can be designed to protrude outward from the outer periphery of the breaker bar 5.

[0022] Furthermore, the number of crushing rods 5 in two adjacent layers decreases in sequence along the vertical direction, so as to mitigate the turbulence effect at the bottom of the reaction barrel 1, so as to avoid re-separation of a variety of different materials under the action of centrifugal force after they are completely dissolved and mixed. In the above, a plate mesh 6 is installed on the periphery of the fixed rod 3, and the periphery of the plate mesh 6 extends to connect with the top of the spiral plate 4, so that the large flocs or "fish eyes" floating on the top side of the solvent can be further ensured to be fully crushed when the solvent passes through the plate mesh 6 under the action of the vortex. Moreover, in order to ensure that the materials at different depths in the reaction barrel 1 are effectively crushed in this embodiment, a plurality of plate meshes 6 are arranged at intervals in the spiral plate 4 along the axial direction of the fixed rod 3, and each plate mesh 6 is located between two adjacent layers of crushing rods 5. Several groups of stirring blades 7 are installed on the periphery of the spiral plate 4. The stirring blades 7 extend from one end away from the fixed rod 3 to the inner wall of the reaction barrel 1 to fully stir the material outside the spiral plate 4. At the same time, the material flowing out of the gap of the spiral plate 4 after eddy current crushing treatment can be quickly mixed with the solvent.
