[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] The following is combined with Figure 1 Detailed description, a method for processing a waterborne coating composition, the method comprising the following steps:

[0038] Step 1: Add water, dispersant, defoamer and preservative into a dispersion tank and stir;

[0039] Step 2: Add the coloring pigment and the body material into the material in step 1 in sequence while stirring the material to complete the preparation of the slurry;

[0041] Step 4: Add a thickener, a pH adjuster, an antifreeze agent, a film-forming aid and a defoamer into the material in step 3 in sequence while stirring the material to complete the preparation of the water-based coating;

[0042] Step 5: Add the slurry and water-based paint into a mixing barrel to complete the processing of the water-based paint composition;

[0043] A processing device is also required to complete the waterborne coating composition processing method.

[0044] The following is combined with Figure 1 Specifically, in step 2, a proper amount of HEC can be added to help dispersion, prevent the slurry from sticking to the wall, and improve the dispersion effect.

[0045] The following is combined with Figure 1 In detail, the defoaming agent is added in a way that half is added to the slurry and the other half is added to the paint preparation process, and the defoaming effect is better.

[0046] According to the instruction manual Figure 2-6 In detail, the processing device includes a processing tank 101, a sealing cover 102, a mixing barrel 103, a supporting leg 104 and a stirring member. The sealing cover 102 is fixedly connected to the processing tank 101 by threads, the mixing barrel 103 is fixedly connected to the bottom of the processing tank 101 by welding, the supporting leg 104 is fixedly connected to the mixing barrel 103 by welding, and the stirring member is rotatably connected to the sealing cover 102 through a hole.

[0047] Furthermore, the preparation of slurry and water-based paint can be completed in the processing tank 101, and the sealing cover 102 can cover and seal the opening above the processing tank 101 to prevent debris from entering the processing tank 101. The slurry processed in the processing tank 101 can be first added to the mixing barrel 103, and then the processing tank 101 is used to prepare the water-based paint, and then the processed water-based paint is transferred to the mixing barrel 103 to achieve mixing of the slurry and the water-based paint. The stirring component can be used to stir the various materials in the processing tank 101, and the various materials in the mixing barrel 103 can also be stirred. When the processing tank 101 is used to process the slurry, the stirring of various materials can be achieved, and when the processed slurry enters the mixing barrel 103, the stirring component can be used not only to stir the materials of the water-based paint, but also to stir the slurry in the mixing barrel 103, thereby preventing the slurry in the mixing barrel 103 from solidifying.

[0048] According to the instruction manual Figure 2-5 In detail, the stirring component includes a reduction motor 201, a stirring shaft 202, a stirring plate I203 and a stirring plate II204. The reduction motor 201 is fixedly connected to the sealing cover 102 by welding. The stirring shaft 202 is rotatably connected to the sealing cover 102 through a circular hole. The stirring shaft 202 is slidably connected to the output shaft of the reduction motor 201 through a square column and a groove. A plurality of stirring plates I203 and a plurality of stirring plates II204 are fixedly connected to the stirring shaft 202 by welding. The plurality of stirring plates I203 are located in the processing tank 101, and the plurality of stirring plates II204 are located in the mixing barrel 103.

[0049] Furthermore, starting the reduction motor 201 can drive the stirring shaft 202 to rotate, and the rotating stirring shaft 202 can drive the multiple stirring plates I203 and the multiple stirring plates II204 to rotate, and the rotating multiple stirring plates I203 and the multiple stirring plates II204 can achieve the stirring process of the various materials in the processing tank 101 and the mixing barrel 103, ensuring that a better quality water-based coating composition can be processed.

[0050] According to the instruction manual Figure 2-6 In detail, the processing device also includes a curved convex plate 205 and a horizontal support column 206. Four curved convex plates 205 are fixedly connected to the sealing cover 102 by welding, and four horizontal support columns 206 are fixedly connected to the reduction motor 201 by welding.

[0051] Furthermore, when the reduction motor 201 is started to drive the stirring shaft 202 to rotate, the four horizontal support columns 206 will also rotate. At this time, the four horizontal support columns 206 will intermittently contact the four curved plates 205, so that the stirring shaft 202 can be moved up and down, thereby driving the multiple stirring plates I203 and the multiple stirring plates II204 to move up and down. At this time, the stirring effect of the various materials in the processing tank 101 and the mixing barrel 103 can be further enhanced, ensuring that the various materials can be evenly mixed together to complete the processing of the water-based coating composition.

[0052] According to the instruction manual Figure 2-6 In detail, the processing device also includes a limiting circular plate 207 and a spring I208. The limiting circular plate 207 is fixedly connected to the stirring shaft 202 by welding. The spring I208 is sleeved on the stirring shaft 202. The spring I208 is located between the limiting circular plate 207 and the sealing cover 102.

[0053] Furthermore, the limiting circular plate 207 plays a limiting role. The elastic force generated by the spring I208 can be used to act on the limiting circular plate 207, so that the limiting circular plate 207 has a tendency to move downward, and the limiting circular plate 207 can drive the stirring shaft 202 to move downward. When the four horizontal supporting columns 206 move to the highest point of the four curved convex plates 205, they will move to the lowest point of the four curved convex plates 205. At this time, the elastic force generated by the spring I208 can be used to act on the limiting circular plate 207 to make it move downward, which can accelerate the downward movement of the stirring shaft 202 and ensure that the stirring shaft 202 can move up and down smoothly.

[0054] According to the instruction manual Figure 2 , 3 , 5 and 6 are described in detail, the processing device also includes a switch slide plug 301 and a telescopic rod 302, the switch slide plug 301 is slidably connected to the bottom of the processing tank 101 through a convex plug, the stirring shaft 202 is slidably connected to the switch slide plug 301 through a circular hole, two telescopic rods 302 are fixedly connected to the switch slide plug 301 by welding, and the processing tank 101 is fixedly connected to the two telescopic rods 302 by welding.

[0055] Furthermore, the switch slide 301 can be used to seal the processing tank 101, and the processed slurry and water-based paint in the processing tank 101 can be sealed to prevent the discharge of the slurry and water-based paint. When the slurry and water-based paint in the processing tank 101 need to be discharged, the two telescopic rods 302 can be started to drive the switch slide 301 to move downward. The upper surface of the switch slide 301 is designed with a conical structure. When the slurry and water-based paint fall on the upper surface of the switch slide 301, the slurry and water-based paint on the switch slide 301 can directly slide down and enter the mixing barrel 103, thereby completing the mixing of the slurry and water-based paint.

[0056] According to the instruction manual Figure 2 , 3 , 5, 6 and 7-11 are described in detail, the processing device also includes a sealing ring 401, an adding component, a storage component and a liquid adding component, the sealing ring 401 is slidably connected in the processing tank 101 through two cylinders, the adding component and the storage component are fixedly connected to the left end of the processing tank 101 by welding, the storage component is located below the adding component, and the liquid adding component is fixedly connected to the right end of the processing tank 101 by welding.

[0057] Furthermore, when it is necessary to add multiple materials to the processing tank 101, the multiple materials can be added to the adding component, and the multiple materials can be filtered out by using the adding component. Impurities in the multiple materials can be filtered out to prevent debris from entering the processing tank 101. The debris filtered out by the adding component can be discharged into the storage component to remove the debris and collect and process it in a unified manner. The defoaming agent can be added to the liquid adding component, and the defoaming agent can be added to the processing tank 101 intermittently in batches using the liquid adding component to achieve defoaming treatment of multiple materials.

[0058] The adding components include a transverse pipe 501, a vertical pipe 502, a cone adding port 503, a blocking slide 504, a limit slide 505, a fixing nail 506, a lifting slide 507, a filter cone plate 508 and a storage chamber 509. The transverse pipe 501 is fixedly connected to the upper part of the left end of the processing tank 101 by welding, the transverse pipe 501 is fixedly connected to the vertical pipe 502 by welding, the upper part of the vertical pipe 502 is fixedly connected to the cone adding port 503 by welding, the lower part of the vertical pipe 502 is slidably connected to the blocking slide 504, and the blocking slide 504 is fixedly connected to the upper part of the vertical pipe 502. A limit slide column 505 is fixedly connected by welding, and the limit slide column 505 is slidably connected to the vertical pipe 502. A fixing nail 506 is slidably connected to the vertical pipe 502. The fixing nail 506 is slidably connected to the limit slide column 505. A lifting slide column 507 is slidably connected to the blocking slide plug 504. The lifting slide column 507 is fixedly connected to the filter cone plate 508 by welding. The filter cone plate 508 is slidably connected in the vertical pipe 502. A storage chamber 509 is slidably connected in the vertical pipe 502, and the storage chamber 509 is located above the filter cone plate 508.

[0059] Furthermore, various materials can be placed in the cone addition port 503, and the various materials located in the cone addition port 503 can enter the vertical through pipe 502, flow into the horizontal through pipe 501, and finally enter the processing tank 101. The blocking slide 504 can be used to block the opening below the vertical through pipe 502 to prevent various materials from flowing out from the bottom of the vertical through pipe 502, and the limiting slide 505 can be used to limit the blocking slide 504, and the fixing nail 506 can be used to fix the limiting slide 505, and the blocking slide 504 can be fixed. The lifting slide 507 can provide a fixed space for the filter cone plate 508, and a spring II is provided on the lifting slide 507, and the spring II is located between the filter cone plate 508 and the blocking slide 504. The elastic force generated by the spring II acts on the filter cone plate 508, so that the filter cone plate 508 is at the highest point. The filter cone plate 508 is provided with a plurality of filter holes. Various materials can flow down from the plurality of filter holes through the filter cone plate 508, while debris can remain on the filter cone plate 508, thereby completing the filtering treatment of various materials. The amount of debris on the filter cone plate 508 can be known by the position of the lifting slide column 507. The fixing nail 506 is pulled to disengage it from the limiting slide column 505. At this time, the blocking slide plug 504 slides down, and the debris on the filter cone plate 508 can be processed. The storage chamber 509 can be used to limit the filter cone plate 508. When the filter cone plate 508 slides away from the vertical pipe 502, the storage chamber 509 will be separated from the filter cone plate 508, and the debris on the filter cone plate 508 can be automatically discharged. The advantage of providing the storage chamber 509 is that the filter cone plate 508 can be limited to prevent debris from entering the horizontal pipe 501, thereby playing an isolation role.

[0060] The storage component includes a fixed frame I601, a debris chamber 602 and a discharge pipe 603.

[0061] Furthermore, the fixed frame I601 can provide a fixed space for the debris chamber 602, and debris can enter the debris chamber 602. The bottom of the debris chamber 602 is designed as a slope, and the drainage pipe 603 is located at the lowest point of the debris chamber 602. When the filter cone plate 508 moves downward, the debris located on the filter cone plate 508 can enter the drainage pipe 603 to achieve storage of the debris.

[0062] The liquid adding component includes a fixed frame II701, a liquid storage barrel 702, a discharge pipe I703 and a discharge pipe II704.

Valves are provided on the drain pipe I703 and the drain pipe II704, which can control whether there is defoaming agent discharged from the drain pipe I703 and the drain pipe II704. The volume of the defoaming agent discharged from the drain pipe I703 is half of the defoaming agent stored in the liquid storage barrel 702, and the other half can be discharged from the liquid storage barrel 702, so that half of the defoaming agent is added to the slurry process, and the other half is added to the paint preparation process without manual proportioning, thereby increasing the processing speed of the water-based coating composition.
