Description

Technical Field

[0001] This utility model relates to the field of chemical raw material production technology, and in particular to a device for preparing a water-based polyurethane coating self-healing repair material. Background Technology

[0002] Waterborne polyurethanes, due to their hydrophilic groups and ability to disperse in water, suffer from several limitations in performance, such as low relative molecular mass leading to weak mechanical properties, poor compatibility with various substrates resulting in limited functionality, and insufficient water resistance after film formation. Therefore, researchers have been exploring ways to functionalize and modify them through changes in raw materials, formulations, and synthesis processes.

[0003] Elevating waterborne polyurethane from simple basic applications to multifunctional, high-performance, and biodegradable mid-to-high-end application materials, and developing environmentally friendly materials with strong mechanical properties, self-healing capabilities, and biodegradability, can not only greatly boost consumer demand for waterborne polyurethane materials but also significantly increase the price of related products, resulting in considerable economic benefits. Glucose, as a biodegradable polyhydroxy aldehyde, has been shown in studies to effectively improve the mechanical properties of waterborne polyurethane as a crosslinking agent. Therefore, modifying self-healing waterborne polyurethane with glucose to develop novel, high-performance, and multifunctional waterborne polyurethane eco-materials is of great significance in broadening the frontier research field of waterborne polyurethane.

[0004] In the preparation of waterborne polyurethane materials with self-healing properties, mixing equipment is usually required to mix different types of raw materials such as glucose with waterborne polyurethane raw materials. However, existing mixing equipment usually uses a stirring rod to enter the mixing cylinder longitudinally for stirring. This not only limits the stirring range, but also filters and separates impurities in the raw materials while stirring, resulting in low purity of the mixed raw materials and affecting the quality of the material.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1 A device for preparing a water-based polyurethane coating self-healing repair material includes a base 1, a support seat 2 fixedly disposed on the upper surface of the base 1, a limiting support frame 3 rotatably connected to the surface of the support seat 2, a mixing cylinder 4 rotatably disposed on the surface of the limiting support frame 3, a mixing and impurity removal mechanism 5 disposed inside the mixing cylinder 4, an electric heating ring 17 fixedly connected to the inner wall of the mixing cylinder 4, and a temperature gauge 18 embedded in the outer wall of the mixing cylinder 4. A control panel 19 is fixedly installed on the base 1.

[0029] Reference Figure 2 In a preferred embodiment, a hydraulic push rod 14 is rotatably provided on the upper surface of the base 1. The telescopic end of the hydraulic push rod 14 is rotatably connected to the bottom of the limiting support frame 3. Two limiting rollers 15 are rotatably connected to the surface of the limiting support frame 3. The limiting rollers 15 are slidably connected to the bottom of the mixing cylinder 4.

[0030] Specifically, by setting the limiting roller 15, the bottom of the mixing cylinder 4 can be limited and supported, thereby improving the stability of the mixing cylinder 4 during rotation and facilitating the mixing of raw materials.

[0031] Reference Figure 4 In a preferred embodiment, a motor mounting slot is provided on the left side of the limiting support frame 3. A drive motor 9 is fixedly installed on the inner wall of the motor mounting slot. A drive gear 10 is fixedly provided on the output shaft of the drive motor 9. A limiting shaft hole is provided on the surface of the limiting support frame 3. A drive sleeve 11 is rotatably connected to the inner wall of the limiting shaft hole through a bearing. A driven gear 12 is fixed on the surface of the drive sleeve 11. The drive gear 10 meshes with the driven gear 12.

[0032] The heating ring 17 and the drive motor 9 are both electrically connected to the control panel 19.

[0033] By setting the drive motor 9, the drive gear 10 can be driven to rotate, which in turn drives the driven gear 12 and the drive sleeve 11 to rotate, which can drive the mixing cylinder 4 to rotate on the surface of the limit support frame 3.

[0034] It should be noted that the right end of the drive sleeve 11 is fixedly connected to the left end of the mixing cylinder 4, and the right end of the drive sleeve 11 extends into the interior of the circular shell 501. A one-way valve cover 16 is fixedly installed inside the drive sleeve 11. The one-way valve cover 16 is used to prevent the liquid inside the drive sleeve 11 from flowing back into the mixing cylinder 4.

[0035] Specifically, the one-way valve cover 16 can be opened unidirectionally toward the left end of the discharge port of the drive sleeve 11, so as to be used during discharge.

[0036] It should be further explained that a fixed plate is fixedly connected to the left end of the drive sleeve 11. The surface of the fixed plate is fixedly embedded with a discharge pipe 13. A discharge valve is fixedly installed on the surface of the discharge pipe 13. After opening the discharge valve, the discharge pipe 13 is connected to the input pipe of the external discharge pump, and the discharge pump can be used to discharge the material.

[0037] Reference Figure 3 and Figure 5 In a preferred embodiment, the mixing and impurity removal mechanism 5 includes a circular shell 501 fixedly connected to the inner wall of the left end of the mixing cylinder 4. The arc-shaped surface of the circular shell 501 is fixedly embedded with a plurality of radially distributed strip-shaped discharge shells 502. The strip-shaped discharge shells 502 are connected to the circular shell 501. The surface of the strip-shaped discharge shells 502 is provided with a plurality of liquid inlet holes 503. The plurality of liquid inlet holes 503 are evenly distributed in a linear array on the surface of the strip-shaped discharge shells 502.

[0038] It is worth noting that by setting several radially distributed strip-shaped discharge shells 502 inside the mixing cylinder 4, the raw materials after mixing can be discharged through the liquid inlet holes 503 on the surface of the strip-shaped discharge shells 502. Thus, the discharge can be carried out while the mixing cylinder 4 is rotating, thereby avoiding the sedimentation of the raw materials after they are in a static state and improving the mixing effect after the raw materials are prepared.

[0039] A support rod 504 is fixedly installed on the surface of the circular shell 501. A limiting installation plate 505 is fixedly connected to the right end of the support rod 504. A cleaning screen cylinder 506 is fixedly connected to the right side of the limiting installation plate 505.

[0040] It is worth noting that by setting a mixing and impurity removal mechanism 5 inside the mixing cylinder 4 for preparing waterborne polyurethane materials, the impurity removal screen 506 can be used to filter and separate particulate matter and impurities in the raw materials during the material preparation process, thereby achieving the function of removing impurities from the raw materials. Furthermore, by using the rolling mixing cylinder 4 and the impurity removal screen 506, it is possible to prevent impurity particles from clogging the filter screen and to collect impurities, which is convenient for subsequent cleaning.

[0041] It should be noted that a cleaning port is provided at the right end of the mixing cylinder 4, and a cover 6 is rotatably provided on the outside of the cleaning port. A sealing block 7 is fixedly connected to the left side of the cover 6. The position of the sealing block 7 corresponds to that of the impurity removal screen cylinder 506, and the size of the sealing block 7 matches that of the impurity removal screen cylinder 506.

[0042] It should be further explained that the surface of the cover 6 is fixedly embedded with a feed pipe 8, the position of the feed pipe 8 corresponds to the impurity removal screen cylinder 506, and the left end of the feed pipe 8 passes through the sealing block 7 and extends into the interior of the impurity removal screen cylinder 506. When the cover 6 is closed, the sealing block 7 can be used to seal the port of the impurity removal screen cylinder 506, so that the feed pipe 8 can enter the raw material first into the impurity removal screen cylinder 506.

[0043] When cleaning impurities inside the impurity removal screen cylinder 506, the cover 6 can be opened to clean the impurities collected in the impurity removal screen cylinder 506.

[0044] Reference Figure 1 and Figure 4 In a preferred embodiment, a plurality of mixing rods 507 are fixedly disposed on the surface of the limiting mounting plate 505, and a plurality of stirring blades 508 are fixedly disposed on the surface of the mixing rods 507. The plurality of mixing rods 507 are evenly distributed in a ring array inside the impurity removal screen cylinder 506, and the plurality of stirring blades 508 are evenly distributed in a linear array on the surface of the mixing rods 507.

[0045] It is worth noting that by setting several mixing rods 507 and stirring plates 508 inside the impurity removal screen cylinder 506, the mixing rods 507 and stirring plates 508 can be used to disperse and stir raw materials in different states during the rotation of the impurity removal screen cylinder 506, which facilitates the mixing of solid raw materials and thick materials, thereby improving the mixing effect between different types of raw materials.

[0046] Working Principle: In operation, various raw materials for preparing waterborne polyurethane coatings are first fed into the mixing cylinder 4 through the feed pipe 8. Then, the cap 6 is closed, and the hydraulic push rod 14 drives the limiting support frame 3 to rotate, thereby adjusting the mixing cylinder 4 to a horizontal position. Next, the drive motor 9 drives the drive gear 10 to rotate, which in turn drives the driven gear 12 and the drive sleeve 11 to rotate. Simultaneously, the mixing cylinder 4 rotates on the limiting roller 15 surface of the limiting support frame 3. After passing through the feed pipe 8, the raw materials first enter the impurity removal screen 506, where they are filtered and impurities are removed. The mixing rod 507 and stirring plate 508 within the impurity removal screen 506 can also be used to mix different types of materials, improving the mixing effect. During discharge, the mixing cylinder 4 can continue to rotate.

[0047] During discharge, the mixing cylinder 4 is adjusted to an inclined state using the hydraulic push rod 14, and then the discharge pipe 13 is connected to the input pipe of the external discharge pump. The discharge pump is then used to extract the contents of the mixing cylinder 4, and the mixed raw materials are sucked into the circular shell 501 through the liquid inlet hole 503 on the surface of the strip-shaped discharge shell 502. The materials are then discharged through the drive sleeve 11 and the discharge pipe 13. During the preparation of waterborne polyurethane, the raw materials are heated and the temperature is controlled by the electric heating ring 17 when the raw materials are mixed.

[0048] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
