[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving protective, decorative, marking, and other special purposes. The authoritative Chinese book on coatings, *Coating Technology*, defines it as follows: "Coating is a material that can be applied to the surface of an object using different construction techniques to form a firmly adhered, continuous solid film with a certain strength. This film is commonly called a coating film, also known as a paint film or coating layer." However, traditional paints contain toxic substances, leading to the emergence of environmentally friendly paints in recent years. However, current technology cannot achieve sequential mixing of multiple raw materials; it can only complete the mixing of multiple raw materials at once, resulting in low-quality environmentally friendly paints.

[0038] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0039] The following is in conjunction with the appendix Figure 1 Detailed description of an environmentally friendly paint preparation process, which includes the following steps:

[0040] Step 1: Add polymer emulsion, leveling agent, bactericide and wetting agent into the processing device and stir to complete the preparation of mixture I;

[0045] Step 6: Fill the semi-finished environmentally friendly paint to complete the preparation of the environmentally friendly paint.

[0046] The following is in conjunction with the appendix Figure 2 The environmentally friendly paint preparation process described above includes the following steps in its processing method:

[0047] S1. Add polymer emulsion, leveling agent, bactericide and wetting agent into mixing tank 101, and use vertical rotating shaft 104 to drive two horizontal stirring plates 105 to rotate, so as to stir the raw materials and complete the preparation of mixture I.

[0048] S2. Add water to mixing tank 101 to mix with mixture I, and continue stirring to form mixture II;

[0049] S3. Add the dispersed zinc stearate slurry to the mixing tank 101 to mix it with mixture II, and continue stirring to form mixture III.

[0050] S4. Add the defoamer to the mixing tank 101 and mix it with the mixture III. Continue stirring to form the mixture IV.

[0051] S5. Add the defoamer to the mixing tank 101 to mix it with the mixture IV, and continue stirring.

[0052] S6. Filter the mixed raw materials in S5 to complete the preparation of environmentally friendly paint semi-finished products.

[0053] According to the instruction manual Figure 1 and 2 In detail, the dispersed zinc stearate slurry is prepared by mixing a dispersant and zinc stearate.

[0054] According to the instruction manual Figure 1 and 2 In detail, when mixing the polymer emulsion, leveling agent, bactericide and wetting agent in S1, the stirring speed is 100 r / min and the stirring time is 5 min.

[0055] According to the instruction manual Figure 1 and2 In detail, when the defoamer in S5 is mixed with the mixture IV, the stirring speed is 100 r / min and the stirring time is 5 min.

[0056] According to the instruction manual Figure 1 and 2 In detail, the pH value of the mixture in S5 is 8.

[0057] According to the instruction manual Figure 1 and 2 In detail, the pH adjustment is accomplished using triethylamine.

[0058] According to the instruction manual Figure 1 and 2 In detail, the internal filtration process in S6 is performed using a 200-mesh silk cloth.

[0059] According to the instruction manual Figure 3-10 In detail, the processing device includes a mixing tank 101 and a support cover plate 102 that is threadedly fixed to the mixing tank 101. A reduction motor 103 is fixedly connected to the support cover plate 102 via a flange plate. A vertical rotating shaft 104 is fixedly connected to the output shaft of the reduction motor 103 via a keyway and a snap ring. Two horizontal stirring plates 105 are fixedly connected to the vertical rotating shaft 104 via welding. A multi-port pipe 106 is fixedly connected to the support cover plate 102 via welding. Multiple auxiliary material storage tanks 107 are uniformly fixedly connected to the mixing tank 101 via welding. A filter component is provided at the bottom of the mixing tank 101.

[0060] Furthermore, the mixing of multiple raw materials is completed in the mixing tank 101, while the supporting cover plate 102 provides a fixed space for the geared motor 103. After the geared motor 103 is started, it can drive the vertical rotating shaft 104 to rotate. The vertical rotating shaft 104 can provide a fixed space for the two horizontal stirring plates 105. When the vertical rotating shaft 104 rotates, it can drive the two horizontal stirring plates 105 to rotate. The polymer emulsion, leveling agent, bactericide and wetting agent enter the mixing tank 101 through the multi-port pipe 106. The multiple auxiliary material storage tanks 107 are at different heights, so that water, dispersant, zinc stearate, defoamer and antifoaming agent can be added to the mixing tank 101 intermittently and sequentially. The mixed raw materials can be filtered by the filter component.

[0061] Water, dispersed zinc stearate slurry, defoamer, and antifoaming agent are sequentially stored in multiple auxiliary material storage tanks 107, with the heights of the water, dispersed zinc stearate slurry, defoamer, and antifoaming agent decreasing sequentially. Polymer emulsion, leveling agent, bactericide, and wetting agent are added to mixing tank 101 through multi-port feed pipe 106. The geared motor 103 is started, and the geared motor 103 drives two horizontal stirring plates 105 to rotate via a vertical rotating shaft 104, thereby agitating the water, dispersed zinc stearate slurry, defoamer, and antifoaming agent entering the mixing tank 101. When the zinc stearate slurry, defoamer, and antifoamer are stirred, the water, dispersed zinc stearate slurry, defoamer, and antifoamer in the multiple auxiliary material storage tanks 107 will flow into the mixing tank 101 in sequence, and the mixing of multiple raw materials will be completed. After the multiple raw materials are mixed, their pH value is tested and adjusted to 8-8.5. Finally, the mixed raw materials will be discharged through the filter component, and the mixed raw materials will be filtered to complete the preparation of the environmentally friendly paint semi-finished product. The environmentally friendly paint semi-finished product will be filled to complete the preparation of the environmentally friendly paint.

[0062] The filter assembly includes multiple discharge pipes 201 with valves, a threaded straight cavity 202, a collecting cone cavity 203, two clamping ring plates 204, and a filter cloth 205. The multiple discharge pipes 201 with valves are evenly arranged on the mixing tank 101. The threaded straight cavity 202 is fixedly connected to the mixing tank 101 by welding. The collecting cone cavity 203 is threadedly connected to the threaded straight cavity 202. The two clamping ring plates 204 are both connected inside the collecting cone cavity 203. The filter cloth 205 is fixed between the two clamping ring plates 204.

[0063] Furthermore, the raw materials mixed in the mixing tank 101 can be discharged through multiple discharge pipes 201 with valves and enter the collecting cone cavity 203. The threaded straight cavity 202 provides space for the collecting cone cavity 203. The mixed raw materials are filtered in the collecting cone cavity 203. The clamping ring plate 204 located below is fixedly connected to the collecting cone cavity 203, and the clamping ring plate 204 located above is slidably connected to the collecting cone cavity 203. The two clamping ring plates 204 are fixedly connected by multiple screws. The advantage of this fixing is that it is convenient to replace the filter cloth 205. The filter cloth 205 can be fixed between the two clamping ring plates 204. The filter cloth 205 can be used to filter the mixed raw materials. When the multiple raw materials are mixed, the valves on the multiple discharge pipes 201 are opened, and the mixed raw materials will fall onto the filter cloth 205 to achieve the filtration of the mixed raw materials, and finally be discharged through the collecting cone cavity 203.

[0064] The processing device also includes an enlarged conical opening 301, a reinforcing plate 302, and a supporting leg 303. The enlarged conical opening 301 is fixedly connected to the multi-port pipe 106 by welding. The reinforcing plate 302 is fixedly connected to the mixing tank 101 by welding. The reinforcing plate 302 is fixedly connected to multiple auxiliary material storage tanks 107 by welding. The supporting leg 303 is fixedly connected to the mixing tank 101 by welding.

[0065] Furthermore, the enlarged conical opening 301 facilitates the passage of polymer emulsions, leveling agents, bactericides, and wetting agents through the multi-port pipe 106. The reinforcing plate 302 reinforces the multiple auxiliary material storage tanks 107 to prevent them from tilting. The supporting legs 303 provide support and fixation, ensuring the device is placed stably on the ground.

[0066] The processing device also includes two central rotating shafts 401, two sets of two horizontal rotating stirring plates 402, two horizontal rotating gears 403, and a fixed gear ring 404. The two central rotating shafts 401 are rotatably connected to the outer ends of the two horizontal stirring plates 105 through round holes. The two sets of two horizontal rotating stirring plates 402 are fixedly connected to the two central rotating shafts 401 by welding. The two horizontal rotating gears 403 are fixedly connected to the two central rotating shafts 401 by keyways and snap rings. The fixed gear ring 404 is fixedly connected to the mixing tank 101 by welding. The fixed gear ring 404 meshes with the two horizontal rotating gears 403 for transmission.

[0067] Furthermore, the two central rotating shafts 401 provide a fixed space for the two sets of two horizontal rotating stirring plates 402. The two sets of two horizontal rotating stirring plates 402 can assist the two horizontal stirring plates 105 in stirring the raw materials. The two horizontal rotating gears 403 can drive the two central rotating shafts 401 to rotate. The fixed gear ring 404 can provide a meshing space for the two horizontal rotating gears 403. When the two horizontal stirring plates 105 rotate, they can drive the two horizontal rotating gears 403 to rotate. The rotating two horizontal rotating gears 403 will drive the two central rotating shafts 401 to rotate, and finally drive the two sets of two horizontal rotating stirring plates 402 to rotate, so as to achieve the mixing and stirring of multiple raw materials in the mixing tank 101. The rotating two sets of two horizontal rotating stirring plates 402 can assist the two horizontal stirring plates 105 in stirring the raw materials, so as to make the multiple raw materials more evenly mixed.

[0068] The processing device also includes a threaded plug cavity 501 and a sliding plate 502. The threaded plug cavity 501 is threadedly connected to the mixing barrel 101, and the sliding plate 502 is fixedly connected to the vertical rotating shaft 104 by welding. The sliding plate 502 and the threaded plug cavity 501 are slidably connected by multiple keyways.

[0069] Furthermore, the threaded plugging cavity 501 can seal multiple auxiliary material storage tanks 107, while the vertical rotating shaft 104 can drive the sliding plate 502 to rotate. When the sliding plate 502 rotates, it can drive the threaded plugging cavity 501 to rotate, allowing the threaded plugging cavity 501 to move downward while rotating. During the downward movement of the threaded plugging cavity 501, the threaded plugging cavity 501 will sequentially unblock multiple auxiliary material storage tanks 107, and the raw materials in the multiple auxiliary material storage tanks 107 will sequentially enter the mixing tank 101, thereby ensuring that water, dispersed zinc stearate slurry, defoamer and antifoaming agent enter the mixing tank 101 in sequence. Without manual control, the sequential discharge of water, dispersed zinc stearate slurry, defoamer and antifoaming agent can be completed during the stirring of polymer emulsion, leveling agent, bactericide and wetting agent, thereby completing the preparation of environmentally friendly paint semi-finished product.
