Description

[0001] This invention relates to the field of waterborne coatings technology, and more specifically to a waterborne coating composition and its processing system and method. Background Technology

[0002] Water-based coatings are coatings that use water as a diluent and do not contain harmful substances such as benzene and toluene. They have advantages such as being environmentally friendly, healthy, and non-flammable. Adding conductive particles to water-based coatings can make them conductive. When applied to the surface of various materials, their conductivity can protect the surface of objects from the effects of static electricity and electromagnetic interference.

[0003] Because conductive particles are insoluble in water-based coatings and tend to settle, the conductivity of the water-based coating is uneven in different parts, which affects the performance of the conductive water-based coating. Summary of the Invention

[0034] A method for processing a water-based coating composition, the method comprising the following steps:

[0035] S1: Weigh the film-forming material, pigment, filler, additives and graphene by weight;

[0036] S2: Grind the material from step S1 into powder;

[0037] S3: Put the ground powder into the processing system and mix with water;

[0038] S4: Dispersing mixtures within the processing system;

[0039] S5: Add additives to adjust the performance parameters of the mixture;

[0040] S6: Discharge the mixture to complete the coating process, and then clean the processing system.

[0041] A water-based coating composition comprises the following raw materials by weight: 600g acrylic resin, 200g graphene, 100g talc, 100g pigment, 50g leveling agent, 40g defoamer, and the balance thickener and diluent.

[0042] like Figure 1-8 As shown, this example demonstrates how to easily prepare water-based coatings with conductive properties.

[0043] The water-based coating composition processing system includes a base 401, a mixing chamber 101 fixedly connected to the upper side of the base 401, a hollow impact chamber 201 fixedly connected inside the mixing chamber 101, a hollow dispersion chamber 301 fixedly connected to the upper side of the impact chamber 201, the lower side of the dispersion chamber 301 communicating with the impact chamber 201, an air inlet pipe 305 fixedly connected to one side of the dispersion chamber 301, a water inlet pipe 304 fixedly connected to the other side of the dispersion chamber 301, and brackets 404 fixedly connected to both ends of the base 401. An air pump 405 is fixedly connected to the upper end of one of the brackets 404. 5 is fixed to the outside of the air inlet pipe 305, and a water pump 406 is fixed to the upper end of the other side bracket 404. The water pump 406 is fixed to the outside of the water inlet pipe 304. The water-based coating raw materials are put into the mixing chamber 101, and then the water is pumped into the water inlet pipe 304 by the water pump 406, and then pumped into the impact chamber 201 through the dispersion chamber 301. The water is then evenly pumped into the mixing chamber 101 through the impact chamber 201, thereby mixing the water-based coating raw materials and evenly mixing the conductive particles and the water-based coating raw materials, thereby completing the preparation of the water-based coating.

[0044] During the mixing of water-based raw materials, high-pressure gas is pumped into the air inlet pipe 305 by the air pump 405, and then evenly dispersed into the impact chamber 201 through the dispersion chamber 301. The high-pressure gas is then evenly sprayed into the mixing chamber 101 through the impact chamber 201, thereby impacting the conductive particles in the mixing chamber 101. This improves the uniformity of the dispersion of the conductive particles in the mixing chamber 101, resulting in a conductive water-based coating with uniform conductivity. The impact of high-pressure gas on the conductive particles helps to mix the conductive particles with the water-based coating, improves the dispersion of the conductive particles, and prevents the conductive particles from depositing at the bottom of the mixing chamber 101 during the mixing process, thus facilitating the preparation of a water-based coating with conductive properties.

[0045] Meanwhile, after the water-based coating is mixed, water can be pumped into the impact chamber 201 by the water pump 406, thereby spraying water evenly inside the mixing chamber 101, which facilitates the removal of residual water-based coating inside the mixing chamber 101 and makes it easier to clean the mixing chamber 101.

[0046] like Figure 1-6 As shown, this example can achieve the effect of mixing water-based coatings.

[0047] In the water-based coating composition processing system, a pressure plate 102 is fixedly connected to the upper side of the mixing chamber 101. A rotating shaft 104 is rotatably connected inside the pressure plate 102, and a mixing plate 105 is fixedly connected to the outer side of the rotating shaft 104. A motor 103 that drives the rotating shaft 104 to rotate is fixedly connected to the upper side of the pressure plate 102. After the motor 103 is started, the rotating shaft 104 is driven to rotate by the motor 103, which in turn drives the mixing plate 105 to rotate. The mixing plate 105 then stirs the raw materials in the mixing chamber 101, thereby achieving the stirring and mixing of the water-based coating and thus achieving the effect of mixing the water-based coating.

[0048] The rotating shaft 104 is fixed by the pressure plate 102, thereby preventing the rotating shaft 104 from vibrating during rotation and affecting the mixing effect of the water-based coating. At the same time, the dispersion chamber 301 is fixed by the pressure plate 102, thereby stabilizing the position of the components during the mixing process.

[0049] like Figure 1-7 As shown, this example can achieve the effect of preventing water-based paint from splashing.

[0050] Because a baffle 303 is fixedly connected to the upper side of the dispersion chamber 301 in the water-based coating composition processing system; the baffle 303 can block the splashing of the mixing plate 105 when mixing the water-based coating raw materials, and at the same time prevent the water-based coating raw materials from being impacted out of the mixing chamber 101 by the impact of high-pressure gas, thereby achieving the effect of preventing water-based coating splashing.

[0051] like Figure 1-7 As shown, this example can facilitate the exhaust of gases.

[0052] Because the baffle 303 in the water-based coating composition processing system is fixedly connected to the upper side of the feed pipe 302, the raw materials of the water-based coating can be conveniently added to the mixing chamber 101 through the feed pipe 302, and the high-pressure gas introduced into the mixing chamber 101 can be discharged at the same time, thereby achieving the effect of easy exhaust.

[0053] like Figure 1-5 As shown, this example can achieve the effect of uniformly injecting high-pressure gas into the mixing chamber 101.

[0054] Because the impact chamber 201 in the water-based coating composition processing system has multiple partitions 202 fixedly connected at uniform intervals inside, and multiple impact holes 203 are uniformly spaced on the inner side of the impact chamber 201, with each impact hole 203 located between two adjacent partitions 202; after the high-pressure gas enters the impact chamber 201 through the dispersion chamber 301, it is evenly separated between two adjacent partitions 202 by the multiple partitions 202, and then sprayed into the mixing chamber 101 through the impact holes 203, which facilitates the uniform entry of high-pressure gas from all sides of the mixing chamber 101, thereby making the mixture uniformly impacted by the high-pressure gas, and thus achieving the effect of uniformly spraying high-pressure gas into the mixing chamber 101.

[0055] like Figure 1-5 As shown, this example can achieve the effect of preventing water-based coatings from entering the impact chamber 201.

[0056] Since a one-way valve 204 is fixedly connected to the inside of each impact hole 203 in the water-based coating composition processing system, the one-way valve 204 inside the impact hole 203 allows gas and water to enter the mixing chamber 101 from the impact chamber 201, while preventing the water-based coating in the mixing chamber 101 from entering the impact chamber 201 through the impact hole 203, thereby achieving the effect of preventing the water-based coating from entering the impact chamber 201.

[0057] like Figure 1-7 As shown, this example can achieve the effect of separating water from high-pressure gas.

[0058] In the water-based coating composition processing system, sealing plates 306 are slidably connected to both sides of the dispersion chamber 301. Springs I 307 are fixedly connected between each sealing plate 306 and the dispersion chamber 301. The two sealing plates 306 are respectively located below the air inlet pipe 305 and the water inlet pipe 304. When the water pump 406 pumps water into the water inlet pipe 304, the water flow squeezes the upper side of the sealing plate 306, thus pushing the sealing plate 306 downwards. This stretches the springs I 307, and simultaneously, the sealing plate 306 no longer obstructs the water inlet pipe 304 and the dispersion chamber 301, allowing water to enter the dispersion chamber 301. Meanwhile, the sealing plate 306 on the other side... The sealing plate 306 is pulled upward by the spring I 307 on the other side, which blocks the air inlet pipe 305, thereby preventing water from entering the air inlet pipe 305 and the air pump 405, which would damage the air pump 405. At the same time, when the air pump 405 is turned on, the high-pressure gas pushes the sealing plate 306 downward, and the sealing plate 306 on the other side is pulled upward by the spring I 307 on the other side, which blocks the water inlet pipe 304, thereby preventing high-pressure gas from entering the water inlet pipe 304 and the water pump 406, which would damage the air pump 405. This achieves the effect of separating water from high-pressure gas.

[0059] like Figure 1-4As shown in Figure 8-11, this example can achieve the effect of facilitating the discharge of mixed water-based coatings.

[0060] Because the mixing chamber 101 in the water-based coating composition processing system has a discharge pipe 106 fixedly connected to its lower side, a fixing groove 402 fixedly connected to the middle of the base 401, a sliding sleeve 502 slidably connected inside the fixing groove 402, a spring II 403 fixedly connected between the sliding sleeve 502 and the fixing groove 402, a switch 501 rotatably connected inside the sliding sleeve 502, a control groove 503 fixedly connected to the upper end of the switch 501, and the discharge pipe 106 slidably connected inside the control groove 503; the elastic force generated by the spring II 403 presses the sliding sleeve 502 upward, thereby pushing the switch 501 upward, thereby pushing the control groove 503 upward, and thus the control groove 503... The water-based coating is squeezed to the bottom of the discharge pipe 106, thereby blocking the outlet of the mixing chamber 101 and preventing the water-based coating from being discharged through the discharge pipe 106. After the water-based coating is mixed, the switch 501 is pushed down, and then the switch 501 is rotated to move the control tank 503 away from the bottom of the discharge pipe 106, so that the mixed water-based coating can be discharged from the mixing chamber 101 through the discharge pipe 106. By controlling the water-based coating inside the mixing chamber 101 through the switch 501 and the control tank 503, leakage of the water-based coating during the mixing process can be prevented, and conductive particles can be prevented from clogging the discharge pipe 106, thereby achieving the effect of facilitating the discharge of the mixed water-based coating.
