[0002] Dendritic polymers, with their highly branched three-dimensional spherical structure, abundant terminal functional groups, and low viscosity, have shown great application potential in high-end fields such as conductive pastes, drug carriers, and functional coatings. However, traditional grinding equipment can only achieve micron-level dispersion and cannot be further broken down to the nanoscale, resulting in low efficiency of conductive / thermal / mechanical enhancement in downstream applications.

[0003] However, existing grinding equipment has insufficient shear strength and cannot effectively destroy the chemical cross-linking network of dendritic polymers, resulting in larger particle sizes after grinding and making it difficult to obtain uniform nanoscale particles. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 - Figure 6 The dendritic polymer network structure gel nanoslurry preparation equipment provided in this embodiment includes a frame 10 and a column 11. The frame 10 is equipped with a grinding component 20 that can grind the dendritic polymer network structure gel into nanoslurry. The grinding assembly 20 includes a movable frame 21 disposed at the top of the frame 10, a grinding frame 22 disposed at the top of the movable frame 21, and a grinding tank 23 disposed on the grinding frame 22. The dendritic polymer network structure gel can be ground in the grinding tank 23. The dendritic polymer network structure gel is obtained by first adding ethylenediamine and methyl acrylate to a solvent to react and obtain a colorless and transparent liquid; then adding the liquid to the solvent with ethylenediamine to react and obtain a pale yellow viscous liquid; then adding nicotinic acid or isonicotinic acid and reacting in the presence of a catalyst to remove the white precipitate, and precipitating in diethyl ether to obtain a viscous liquid; finally, washing the obtained viscous liquid, dissolving it with distilled water, evaporating the solution to obtain a yellow solid, i.e., dendritic polymer. By placing the yellow solid in the grinding tank 23 for grinding, it forms a nano-slurry. The nano-sized particles can provide more conductive pathways. In conductive composite materials, nanoparticles can be more tightly filled in the matrix to form a continuous conductive network, thereby improving the conductivity of the material. Several partitions 24 are fixedly installed in the middle of the grinding tank 23. The distance between the partitions 24 is at the nanometer level. The two sides of the grinding tank 23 are set as inclined surfaces. The inclined surfaces can prevent accumulation and grinding dead corners. The grinding roller 25 is set on the column 11. The grinding frame 22 is also equipped with a pushing component 26 that can push the ground gel to grind it back and forth. The column 11 is equipped with a driving component 30 that can drive the grinding roller 25 to grind the gel. The frame 10 is also equipped with a moving component 40 that can move the grinding frame 22 out.

[0017] Reference Figure 2 Specifically, in order to drive the movable frame 21 to move the top grinding frame 22 for loading and unloading, a movable assembly 40 is provided. The movable assembly 40 includes a limiting rod and two lead screws 41 symmetrically arranged on the frame 10. The movable frame 21 is threaded onto the two lead screws 41, which are rotatably connected to the frame 10. The movable frame 21 can move by rotating the lead screws 41 and is slidably connected to the limiting rods. While the movable frame 21 moves, it is kept stable by the limiting rods. A synchronous belt 42 meshes between the two lead screws 41. The meshing transmission of 2 enables the two lead screws 41 to rotate synchronously. One of the lead screws 41 is fixedly connected to the output end of the motor 43. In use, the dendritic polymer network structure gel is placed in the grinding tank 23, and then the motor 43 is started. The motor 43 drives the rotation of the lead screw 41 connected to it. Through the meshing transmission of the synchronous belt 42, the two lead screws 41 can rotate synchronously, which in turn causes the moving frame 21 to move the top grinding frame 22 to below the grinding roller 25, where grinding can be performed.

[0018] Reference Figure 5 - Figure 6 Specifically, in order to enable the grinding roller 25 to grind the dendritic polymer network structure gel, a drive assembly 30 is provided. The drive assembly 30 includes a lead screw 31 and a motor 32 mounted on the column 11. A support frame 33 is threaded onto the lead screw 31 and slidably connected to the column 11. The rotation of the lead screw 31 allows the support frame 33 to be raised and lowered, and it is kept stable by the column 11. A slide 34 is slidably mounted on the support frame 33. A motor 35 is fixedly mounted on the slide 34. An electric actuator 36 is fixedly connected between the slide 34 and the support frame 33. The electric actuator 36 can drive the slide 34 to move on the support frame 33.

[0019] In more detail, the lead screw 31 is fixedly connected to the output end of the motor 32. The motor 32 can drive the lead screw 31 to rotate. The grinding roller 25 is rotatably mounted on the slide 34. A belt is provided between the grinding roller 25 and the output end of the motor 35. When the output end of the motor 35 rotates, the grinding roller 25 will also rotate through the belt drive.

[0020] In more detail, the size of the grinding roller 25 is adapted to the grinding groove 23, allowing the grinding roller 25 to descend into the grinding groove 23. A scraper is fixedly installed on the slide 34, and the scraper is in contact with the surface of the grinding roller 25. The scraper can prevent residue from remaining on the surface of the grinding roller 25. When the moving frame 21 moves the top grinding frame 22 to below the grinding roller 25, the motor 32 is started, which drives the lead screw 31 to rotate, causing the support frame 33 to lower the grinding roller 25 into the grinding groove 23. Then, the motor 35 is started. When the output end of the motor 35 rotates, the grinding roller 25 will also rotate through the belt drive. At the same time, the electric actuator 36 is started. The electric actuator 36 drives the carriage 34 to move on the support frame 33, thereby enabling the grinding roller 25 to reciprocate within the grinding groove 23. This continuously grinds the dendritic polymer network structure gel at the top of the partition 24. Since the distance between the partitions 24 is on the nanometer scale, this nanometer-scale spacing generates extremely high shear force, which helps to efficiently break down the three-dimensional network structure of the dendritic polymer network structure gel, thus grinding it into smaller particles and achieving a nanometer-scale dispersion effect. This keeps the size of the ground particles within the target range. Secondly, the nanometer-scale spacing of the partitions 24 forces the material to pass through uniformly, reducing particle inhomogeneity and missed areas during grinding, and improving grinding efficiency. Furthermore, this design can also create numerous "shear hot spots" at the microscale, allowing the grinding process to more specifically target the chemical bonds or physical network of the dendritic polymer network structure gel, further enhancing the grinding effect.

[0021] Reference Figure 2 - Figure 4Specifically, in order to make the dendritic polymer network structure gel more thoroughly ground, a pushing component 26 is provided. The pushing component 26 includes a lifting plate 261 slidably mounted on the grinding tank 23, and several vertical plates 262 fixedly mounted on the lifting plate 261 and located between several partitions 24. The lifting plate 261 can drive the vertical plates 262 to rise and fall, thereby pushing out the dendritic polymer network structure gel between the partitions 24. At this time, the vertical plates 262 fill the nanometer-level distance between the partitions 24 to form a complete plane, so that the pushed-out dendritic polymer network structure gel can be ground again. This process is repeated. A rectangular frame 263 is fixedly mounted on the bottom of the grinding frame 22, and an electric push rod 264 is fixedly mounted on the rectangular frame 263. The lifting plate 261 is fixedly mounted on the output end of the electric push rod 264. The electric push rod 264 can reciprocate to drive the lifting plate 261 to drive the vertical plates 262 to rise and fall.

[0022] In more detail, the rectangular frame 263 is slidably mounted on the movable frame 21, and the electric push rod 265 is fixedly mounted on the movable frame 21. The rectangular frame 263 is fixedly connected to the output end of the electric push rod 265. The vibrator 266 (model YBZD series) is set on the grinding frame 22. The electric push rod 265 can drive the movable frame 21 to move back and forth in a small amplitude during grinding. In conjunction with the vibrator 266, the grinding frame 22 is vibrated, which can shake the dendritic polymer network structure gel inside the grinding frame 22 to prevent it from accumulating.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
