Description

Technical Field

[0001] The invention relates to a production process, in particular to a water-soluble paint production process and dispersion equipment applied in the field of paint dispersion technology. Background Art

[0002] Paint has been deeply rooted in the hearts of consumers, but the paint can only be moved in one month after it is applied. Consumers think that the paint is no longer toxic at this time. In fact, this is wrong. The lack of irritating odor is only because the formaldehyde evaporates to a level that is acceptable to human physiology, while the benzene, toluene, and free TDI contained in the paint curing agent and diluent are still evaporating. It takes at least several decades for these things to completely evaporate, and these aromatic hydrocarbons have a certain impact on the intellectual development of infants and unborn children. Therefore, at this stage, the Institute has developed a water-based solvent that saves a lot of resources, eliminates the risk of fire during construction, reduces air pollution, and uses only a small amount of low-toxic alcohol ether organic solvents to improve the working environment. The organic solvent of general water-based paint (accounting for paint) is between 5% and 15%, while the cathodic electrophoretic paint has dropped to less than 1.2%, which has a significant effect on reducing pollution and saving resources.

[0003] However, water-soluble paint will produce dust during the preparation process, which affects the health of workers. The raw materials are easily unevenly stirred during the dispersion process, resulting in substandard quality of the finished product. It is very easy to re-agglomerate during storage and use, resulting in low purity. In order to solve these problems, when making water-soluble paint, changing the stirring rules and adding an appropriate amount of solvent has become the production method of most manufacturers in the market.

[0004] Chinese invention patent CN219252327U, the specification discloses a stirring component and a stirring kettle for producing water-soluble insulating paint. The technical scheme discloses a stirring component and a stirring kettle for producing water-soluble insulating paint, comprising: a stirring kettle, a mounting plate is provided on one outer wall of the stirring kettle, a motor 1 is installed on one outer wall of the mounting plate, and a driving gear is installed on the outer wall of the stirring kettle away from the motor 1; in actual use, the motor 1 is started to rotate the driven gear to drive the piston sleeve to rotate, so that the stirring rod rotates through the threaded sleeve, the motor 2 is turned on to drive the threaded rod to rotate, so that the threaded sleeve slides on the inner wall of the sliding sleeve, and the stirring rod on the inner wall slides up and down, thereby changing the position of the stirring plate, so that the stirring depth can be adjusted at any time during the stirring process.

[0005] However, in actual use, by adjusting the position of the stirring blade and changing the stirring depth, the stirring efficiency is improved. When the amount of material to be stirred is large, the stirring blade moving up and down disperses and mixes the material. When the content of the material put into the stirring tank is low, the material accumulates and is dispersed at the bottom of the stirring tank, causing the lower half of the stirring blade to contact the material, resulting in poor dispersion effect, making it unable to fully disperse materials of different contents, and even causing air impurities in the dispersion process, polluting the environment and causing physical harm to the staff. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when the content of the material put into the stirring tank is low, the material is accumulated and dispersed at the bottom of the stirring tank, causing the lower half of the stirring plate to contact the material, resulting in poor dispersion effect, resulting in the inability to fully disperse the materials of different contents, and even causing air impurities in the dispersion process, polluting the environment and causing physical harm to the staff.

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: A water-soluble paint production process comprises the following steps: S1. Mixing, dispersing and stirring: Start the dispersing equipment, add the water-based base material and solid pigment or pigment slurry into the dispersing equipment according to the formula ratio, mix the raw materials preliminarily to form a coating solution, add the water-based base material and solid pigment or pigment slurry into the container of the dispersing equipment according to the formula ratio, and mix the two preliminarily through mechanical actions such as stirring or shearing. Then, based on the mixing, the dispersing equipment uses physical actions such as high-speed rotating shear force, impact force or centrifugal force to refine the solid pigment particles, break their agglomeration state, and evenly disperse them into the water-based base material. This process may include multiple cycles and refinement treatments to ensure sufficient dispersion of the pigment particles; S2. Adjust viscosity: Add thickener or solvent to the coating solution in the dispersing device to adjust the viscosity of the coating solution to a preset value. The coating system after dispersion treatment needs to maintain a certain stability to prevent the pigment particles from reaggregating during storage and use. The dispersing device can fully mix the various components by adjusting the stirring speed and temperature to ensure the uniformity and stability of the water-soluble paint. It can also be adjusted by adding thickener or solvent. The adjustment of viscosity can make the construction performance of the water-soluble paint easier to operate and give full play to its application effect; S3. Grinding: The coating solution with adjusted viscosity is transferred to a grinder for grinding and dispersion, so that various pigments and resin particles in the water-soluble paint become finer, thereby improving the quality and glossiness of the paint film; S4. Quality inspection: The ground raw materials are inspected for appearance, viscosity, drying time and weather resistance to ensure that the quality of the water-soluble paint meets the requirements.

[0021] See also Figure 1 , Figure 3 and Figure 5 , a dispersion device for a water-soluble paint production process, comprising a stirring tank 1, a substrate 2 and an intelligent dispersion controller 3.

[0022] A cylinder cover 11 is provided at the top of the mixing cylinder 1, a discharge port 12 is provided at the bottom of the mixing cylinder 1, and telescopic cross bars 22 are provided on both sides of the cylinder body of the mixing cylinder 1. By arranging a feeding port 104 and a discharge port 12 on the cylinder body, materials can be added and the dispersed materials in the mixing cylinder 1 can be taken out, thereby reducing resource waste during assembly and packaging. A stirring rod 102 is rotatably connected in the mixing cylinder 1, and a stirring motor 103 is installed on the top of the stirring rod 102 for stirring control.

[0023] The base 2 is arranged below the mixing cylinder 1, with telescopic parts 21 fixed at both ends of the base 2, and a driving motor 202 is installed on the top of the telescopic part 21 to control the movement of the telescopic part 21. The top of the telescopic part 21 is rotatably connected to the end of the telescopic cross bar 22 away from the mixing cylinder 1. The telescopic part 21 and the telescopic cross bar 22 are an integral structure, which reinforces the movement of the mixing cylinder 1 and improves stability. The telescopic part 21 and the telescopic cross bar 22 are linked to each other to prevent safety accidents caused by the movement of the mixing cylinder 1, and allow the mixing cylinder 1 to shake the cylinder body during the mixing process to disperse the particulate matter more fully. A distance sensor 109 facing the telescopic cross bar 22 is installed on the telescopic part 21 to detect the distance between the telescopic cross bar 22 and the mixing rod 1 during the dispersion process.

[0024] The intelligent dispersed controller 3 is provided with a stirring control module, a tilting control module and a blocking signal module. The stirring control module is electrically connected to the tilting control module and the stirring motor 103 respectively. The stirring control module starts the stirring motor 103 by sending a stirring signal to the stirring motor 103. The stirring control module and the tilting control module work through the blocking signal. The tilting control module is electrically connected to the driving motor 202 and the distance sensor 109 respectively. The distance sensor 109 detects the distance between the telescopic part 21 and the stirring cylinder 1. When the set range is reached, the in-position signal is sent to the tilting control module, and the tilting control module analyzes the signal and transmits the tilting signal and the stop signal to the driving motor 202. The driving motor 202 is electrically connected to the telescopic part 21. The driving motor 202 sends a telescopic signal to the telescopic part 21 to move. The blocking signal module is electrically connected to the tilting control module and the stirring control module respectively, and transmits a blocking signal to the two modules to stop the dispersion device from working.

[0025] See also Figure 1-Figure 4 The stirring rod 1 has a cylindrical body, and a soft ring pad 23 is provided in the center of the base 2 to further ensure the dispersion process. The stirring motor 103 is installed on the top of the cylinder cover 11. The output shaft of the stirring motor 103 is connected to the stirring rod 102 through a coupling 101. The discharge port 12 is provided with a discharge filter 120. During the unloading process, the dispersed material can be further sieved and refined. A feeding port 104 is provided on the top of the cylinder cover 11 to reduce the waste of resources when assembling raw materials. A mounting plate 108 is provided on one side of the stirring motor 103 to fix the stirring motor 103.

[0026] See also Figure 2 and Figure 7An air filter tube 105 penetrating the cylinder cover 11 is arranged on one side of the cylinder cover 11 corresponding to the feeding port 104, and a filter screen 106 matching it is fixedly installed in the air filter tube 105. When the dispersion process is running, powder particles will float, and the substances can be filtered through the air filter tube 105. Pressure sensors 107 are arranged on both sides of the filter screen 106, which can send out a blockage signal when the pressure difference on both sides of the filter screen 106 is large, and inform the intelligent dispersion controller 3 that the dust amount exceeds the standard and the machine operation fails. While avoiding safety accidents, it can also reduce the pollution of dust to the environment. The filter screen 106 is detachable, which also provides convenience for cleaning.

[0027] See also Figure 8 and Fig. 9 The interior of the telescopic cross bar 22 is a hollow cavity, and a movable wood 204 with a notch in the middle is arranged inside the telescopic cross bar 22. When the telescopic member 21 rises on one side, the corresponding movable wood 204 slides toward one end of the telescopic member 21 through the hollow inner cavity. When the telescopic member 21 falls on the other side, the corresponding movable wood 204 slides toward one end of the mixing tank 1 through the hollow inner cavity, so that the mixing tank 1 can be shaken left and right. A driving motor 202 is installed at the connection between the telescopic member 21 and the movable wood 204. The driving motor 202 drives the telescopic member 21 to move it up and down. At the same time, the movable wood 204 rotates up and down along the connection with the telescopic member 21. The mechanical structure of this design makes the mixing tank 1 more flexible during the mixing process.

[0028] See also Figure 1 and Figure 5 The driving motor 202 is electrically connected to the intelligent distributed controller 3 , and the stirring motor 103 is electrically connected to the intelligent distributed controller 3 .

[0029] It can be seen that the structural design of the present invention is ingenious in that by providing the cylinder body with a feeding port 104 and a discharging port 12, materials can be added and the dispersed materials in the mixing cylinder 1 can be taken out, thereby reducing the waste of resources during assembly and packaging. The interior of the telescopic cross bar 22 is a hollow cavity, and a movable wood 204 with a notch in the middle is arranged inside the telescopic cross bar 22. When the telescopic member 21 rises on one side, the corresponding movable wood 204 slides toward one end of the telescopic member 21 through the hollow inner cavity. When the telescopic member 21 falls on the other side, the corresponding movable wood 204 slides toward one end of the mixing cylinder 1 through the hollow inner cavity, so that the mixing cylinder 1 can be shaken left and right. A driving motor 202 is installed at the connection between the telescopic member 21 and the movable wood 204. The driving motor 202 drives the telescopic part 21 to move it up and down. The mechanical structure of this design makes the mixing cylinder 1 more flexible during the mixing process, strengthens the movement of the mixing cylinder 1, and improves stability. During operation, the movement of the mixing cylinder 1 can prevent safety accidents caused by the movement of the mixing cylinder 1. At the same time, the distance sensor 109 installed on the telescopic part 21 detects the moving distance of the telescopic cross bar 22 in real time, sends an electrical signal to the intelligent distributed controller 3, and controls the up and down movement of the telescopic part 21 and the mixing operation of the mixing motor 103 through the mixing control template and the tilt control template. The blocking signal module sends an electrical signal to control the tilt control module and the mixing control module to prevent safety hazards.

[0030] In the design of the mixing tank 1, an air filter tube 105 is arranged on one side of the cylinder cover 11 and passes through the cylinder cover 11. A filter screen 106 is arranged in the middle of the air filter tube 105 to separate it. When the dispersion process is running, powder and particulate matter will float, and the matter can be filtered through the air filter tube 105. The pressure sensor 107 arranged on both sides of the filter screen 106 can send a blockage signal when the pressure difference on both sides of the filter screen 106 is large, and inform the intelligent dispersion controller 3 that the dust amount exceeds the standard and the machine operation fails. While avoiding safety accidents, it can also reduce the pollution of dust to the environment. The filter screen 106 is detachable, which also provides convenience for cleaning. The discharge filter screen 120 arranged at the discharge port 12 can further sieve and refine the dispersed material during the unloading process, and the soft ring pad 23 arranged on the base 2 also provides safety protection to a certain extent.

[0031] The second implementation method: See also Figure 6 , Figure 8 and Fig.10, which is different from the first embodiment, in this embodiment, the stirring blade 110 arranged on the stirring rod 102 is a hollow cavity, and a fan blade tube 121 is installed in the stirring blade 110. When the stirring cylinder 1 is running and shaking the cylinder body, the overall structure of the telescopic member 21 and the telescopic cross bar 22 is linked to shake the cylinder body left and right, and the solution in the cylinder body enters the stirring blade 110 cavity through a plurality of surrounding holes 111 arranged on the stirring blade 110 on one side of the inclined direction, and the fan blade tube 121 is squeezed to be closely attached to the inner cavity of the stirring cylinder 1, and at the same time, the fan blade tube 121 away from the stirring blade 110 on the inclined side falls inward, and the solution in the cavity flows out through the hole 111 and is fully dispersed, and this special structure also During the process, the cylinder body can be divided into multiple spaces to further evenly disperse the materials in the cylinder body to achieve the desired effect. A pressure sensor 113 is arranged in the hole 111 close to the stirring rod 102. The pressure sensor 113 is electrically connected to the stirring control module and the blockage signal module respectively. When the pressure in the inner cavity of the stirring blade 110 is greatly different from the normal operating pressure, a blockage signal is sent to remind the operator that the inner cavity of the stirring blade 110 is blocked, and the operator is reminded to clean it to ensure the normal operation of the equipment. A plurality of curved stirring blades 112 are arranged at intervals between the lower end of the stirring rod 102 and the stirring blade 110, which play a role in further evenly dispersing the materials in the cylinder body during the dispersion process.

[0032] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
