Description

Technical Field

[0001] The invention relates to the technical field of coating preparation, in particular to a wear-resistant and waterproof epoxy anticorrosive coating and a preparation method thereof. Background Art

[0002] Wear-resistant and waterproof epoxy anti-corrosion coating is a high-performance coating that combines wear resistance, waterproofness and corrosion resistance, and is suitable for a variety of harsh environments.

[0003] When processing wear-resistant and waterproof epoxy anti-corrosion coatings, different types of coatings usually need to be mixed. In the prior art, the method for mixing wear-resistant and waterproof epoxy anti-corrosion coatings is generally to use corresponding stirring components for processing. Although this method can complete the mixing of wear-resistant and waterproof epoxy anti-corrosion coatings, the stirring technology in the prior art has a significantly different degree of mixing near the rotating rod than at the end far from the rotating rod. This makes the coating far from the end of the rotating rod often require more time to mix and stir. Therefore, this mixing method may cause uneven mixing of coatings at different positions.

[0004] Therefore, the existing demand is not met, and we propose a wear-resistant and waterproof epoxy anti-corrosion coating and a preparation method thereof. Summary of the invention

[0005] The present invention provides a wear-resistant and waterproof epoxy anti-corrosion coating and a preparation method thereof.

Since a suction plate is threadedly connected to the rotating shaft, the suction plate will move right when the rotating shaft rotates clockwise, so that the movable sleeve can effectively suck the coating into the movable sleeve after the movement is completed. Since the rotating shaft will drive the inner core rotating rod to rotate synchronously when the rotating shaft rotates, after the coating is sucked into the movable sleeve, the coating entering the movable sleeve can be rotated and mixed for the second time, so as to effectively improve the mixing degree of this coating, thereby solving the problem mentioned in the above background technology that the coating far away from one end of the rotating rod often requires more time to be mixed and stirred.

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention provides a mixing assembly on the mixing rotating rod. When the mixing rotating rod rotates, the mixing sleeve and the movable sleeve in the mixing assembly will rotate along with the mixing rotating rod, thereby effectively completing the rotational mixing effect of the paint injected into the preparation chamber. Through the setting of the first sliding groove, after the inner core rod rotates along with the mixing rotating rod, the inner core rod will reciprocate in the mixing rotating rod in the up and down directions. At the same time, since a movable connecting rod is also provided between the inner core rod and the movable sleeve, when the inner core rod reciprocates in the up and down directions inside the mixing rotating rod, the movable sleeve will reciprocate in the left and right directions inside the mixing sleeve under the connection of the movable connecting rod.

As a result, when the inner core rod reciprocates in the up and down directions inside the rotating rod, the rotating shaft will also perform staged clockwise and counterclockwise rotations. Since a suction plate is connected to the rotating shaft, when the rotating shaft rotates clockwise, it will drive the suction plate to move right accordingly, so that the moving sleeve can effectively suck the paint into the moving sleeve after the movement is completed. Since the rotating shaft will drive the inner core rotating rod to rotate synchronously when it rotates, after the paint is sucked into the moving sleeve, this part of the paint entering the moving sleeve can be rotated for a second time for mixing, so as to effectively improve the mixing degree of this part of the paint.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figure 1-Figure 9 , a method for preparing a wear-resistant and waterproof epoxy anticorrosive coating, comprising the following steps: S1. Weigh 15%-23% deionized water, 30%-40% bisphenol A epoxy resin, 8%-15% fluorocarbon emulsion, 5%-10% silicone, 5%-10% nano hollow glass fiber, 10%-18% nitrile rubber, 0.5%-0.9% dispersant, 0.4%-0.8% defoamer, and 0.4%-0.8% preservative respectively, add them together into a mixing device, and use the mixing device to disperse and stir for 5-10 minutes to obtain a mixture; S2, weighing 10%-17% of flaky high wear-resistant pigment and filler and 0.2%-0.5% of leveling agent, adding them to the mixture, and dispersing and stirring in a mixing device for 10-15 minutes to obtain the desired coating; The flaky high wear-resistant pigment filler is composed of 320 mesh glass flakes with a content of 2%-4%, 160 mesh glass flakes with a content of 3%-6%, and 5%-7% sericite powder; the above percentages are all weight percentages, the dispersant can be TH-904 or SN-5040, and the leveling agent can be RM-2020; The mixing device comprises a preparation tank 1, wherein a preparation chamber 102 is provided inside the preparation tank 1, and a mixing rotating rod 103 is rotatably arranged inside the preparation chamber 102. Figure 1 and Figure 2It can be seen that since a drive motor 101 is installed on the top of the preparation tank 1, and a fixed connection is formed between the output end of the drive motor 101 and the mixing rod 103, when the user injects the paint to be mixed into the preparation chamber 102 from the feed port opened on the top of the preparation tank 1, the user can start the drive motor 101, thereby driving the mixing rod 103 to rotate synchronously.

[0031] Several groups of mixing components 2 for mixing paint are arranged on the mixing rotating rod 103, and each group of mixing components 2 is composed of a mixing sleeve 201 and a movable sleeve 202. One end of the mixing sleeve 201 is fixedly arranged on the mixing rotating rod 103, and the movable sleeve 202 is slidably arranged on the inner wall of the mixing sleeve 201. Through this connection method, when the mixing rotating rod 103 rotates, several groups of mixing sleeves 201 and movable sleeves 202 will synchronously rotate with the mixing rotating rod 103, thereby effectively completing the rotational mixing of the paint injected into the preparation cavity 102.

[0032] When the mixing rod 103 rotates, the coating closer to one end of the mixing rod 103 is mixed better than the coating farther from the other end of the mixing rod 103. Therefore, an inner core rod 104 is slidably arranged inside the mixing rod 103. This arrangement allows the inner core rod 104 to rotate synchronously with the mixing rod 103 when the mixing rod 103 rotates. At the same time, a first slide groove 105 is provided on the inner wall of the top of the preparation tank 1. One end of a first connecting rod 108 is connected to the top end of the inner core rod 104. A first limiting ball 107 is installed on the other end of the first connecting rod 108. The first limiting ball 107 is slidably arranged inside the first slide groove 105. Therefore, when the inner core rod 104 rotates with the mixing rod 103, the first connecting rod 108 arranged on the inner core rod 104 will rotate inside the first slide groove 105 through the first limiting ball 107.

[0033] See also Figure 3 It can be seen that since a wave groove 111 for changing the moving trajectory of the first limiting ball 107 is also opened on the inner wall of the first slide groove 105, when the first limiting ball 107 rotates inside the first slide groove 105, the wave groove 111 drives the first limiting ball 107 to move back and forth in the up and down directions inside the first slide groove 105, and then drives the inner core rod 104 to move back and forth in the up and down directions inside the mixing rotating rod 103.

[0034] It should be noted that, since a first movable groove 106 is also provided on the mixing rotating rod 103, when the first limiting ball 107 moves downward under the drive of the wave groove 111, and then drives the first connecting rod 108 to move downward, the opening of the first movable groove 106 can also ensure that the first connecting rod 108 can move smoothly to avoid getting stuck.

[0035] See also Figure 4 It can be seen that since a movable connecting rod 109 is provided between the movable sleeve 202 and the inner core rod 104, and the two ends of the movable connecting rod 109 are movably connected to the inner core rod 104 and the movable sleeve 202, when the inner core rod 104 moves upward, the movable sleeve 202 is stretched by the movable connecting rod 109 through the connection of the movable connecting rod 109, and then the inner core rod 104 moves upward. Figure 4 Similarly, when the inner core rod 104 moves downward, the movable sleeve 202 is squeezed by the movable connecting rod 109, thereby allowing the movable sleeve 202 to move inside the mixing sleeve 201. Figure 4 The leftward movement in the direction can also allow the leftward moving sleeve 202 to extend out of the mixing sleeve 201 through this arrangement, thereby effectively increasing the mixing range of the mixing sleeve 201, thereby improving the mixing efficiency of the coating to a certain extent.

[0036] In this embodiment: by setting a mixing component 2 on the mixing rod 103, when the mixing rod 103 rotates, the mixing sleeve 201 and the movable sleeve 202 in the mixing component 2 will rotate along with the mixing rod 103, thereby effectively completing the rotational mixing effect of the paint injected into the preparation cavity 102.

[0037] Since the first slide groove 105 is provided at the inner wall of the top of the preparation tank 1, and the inner wall of the first slide groove 105 is also provided with a wave groove 111, when the inner core rod 104 rotates following the mixing rotating rod 103, the first connecting rod 108 and the first limiting ball 107 arranged on the inner core rod 104 will rotate inside the first slide groove 105, and the first limiting ball 107 and the first connecting rod 108 will reciprocate up and down inside the first slide groove 105 due to the restriction of the wave groove 111, thereby driving the inner core rod 104 to reciprocate synchronously. At the same time, since a movable connecting rod 109 is provided between the inner core rod 104 and the movable sleeve 202, when the inner core rod 104 reciprocates in the up and down directions inside the mixing rotating rod 103, the movable sleeve 202 will reciprocate in the left and right directions inside the mixing sleeve 201 under the connection of the movable connecting rod 109. This arrangement also allows the movable sleeve 202 to extend continuously outside the mixing sleeve 201, thereby effectively improving the mixing range of the mixing sleeve 201 for the paint, thereby improving the mixing efficiency of the paint to a certain extent.

[0038] Embodiment 2: This embodiment is intended to solve the problem that even if the moving sleeve 202 extends beyond the mixing sleeve 201, it is not enough to fully mix and stir the coating far from the end of the mixing rotating rod 103. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 9Since a movable rack 110 is also provided on the surface of the inner core rod 104, a rotating gear 205 is installed on the rotating shaft 204, and the rotating gear 205 and the movable rack 110 are meshed with each other, when the inner core rod 104 moves downward inside the mixing rotating rod 103, the movable rack 110 provided on the inner core rod 104 will mesh with the rotating gear 205, thereby driving the rotating shaft 204 fixedly connected with the rotating gear 205 to rotate accordingly.

[0039] It should be noted that one end of the rotating shaft 204 is movably arranged inside the inner core rod 104, and a limiting slide groove 113 is provided on the inner core rod 104. A second limiting ball 112 is installed on the other end of the rotating shaft 204, and the second limiting ball 112 is slidably arranged inside the limiting slide groove 113. On the one hand, since the limiting slide groove 113 for the second limiting ball 112 to slide is also provided inside the inner core rod 104, this arrangement can not only prevent the rotating shaft 204 from moving, but also when the inner core rod 104 moves in the up and down directions, the rotating shaft 204 will only slide on the inner core rod 104, and the rotating shaft 204 will not be separated from the inner core rod 104. The movable sleeve 202 is provided with a first cavity 215 and a second cavity 217, respectively. The first cavity 215 is provided with a suction plate 212 and a movable plate 213, respectively. The suction plate 212 and the movable plate 213 are both sleeved on the rotating shaft 204. The shaft of the rotating shaft 204 is provided with a spiral movable groove 220. The suction plate 212 is slidably arranged in the spiral movable groove 220 through a slider. This makes it possible that when the rotating shaft 204 rotates, the spiral movable groove 220 arranged on the rotating shaft 204 will also rotate. Since the suction plate 212 is slidably arranged in the second cavity 217, through this limiting method, the suction plate 212 will rotate on the rotating shaft 204 under the rotation of the spiral movable groove 220. Figure 6 The suction plate 212 moves rightward in the right direction, and a limit slider is fixedly provided at the bottom of the suction plate 212. The limit slider is slidably provided in a slide groove provided on the movable sleeve 202 to limit the left and right sliding of the suction plate 212.

[0040] Since a sealing plate 208 for sealing the interior of the movable sleeve 202 cavity is provided at one end of the movable sleeve 202 away from the inner core rod 104, the interior of the movable sleeve 202 cavity is in a closed state at this time, which means that when the suction plate 212 moves to the right, a corresponding negative pressure will be generated in the space on the left side of the suction plate 212.

[0041] It should be noted that when the suction plate 212 is Figure 6 When the inner core rod 104 moves downward, the movable sleeve 202 moves inside the mixing sleeve 201. Figure 4 Direction leftward.

[0042] See also Figure 7 It can be seen that, since the inner wall of the mixing sleeve 201 is provided with a second movable groove 211, one end of the second connecting rod 210 is connected to the blocking plate 208, and the other end of the second connecting rod 210 is installed with a third limiting ball 222, and the third limiting ball 222 is slidably arranged inside the second movable groove 211, when the movable sleeve 202 moves left inside the mixing sleeve 201, the second connecting rod 210 and the third limiting ball 222 connected to the blocking plate 208 will slide inside the second movable groove 211, see Figure 7 and Fig. 9 It can be seen that since the second movable groove 211 is composed of a movable straight groove 2111 and a movable arc groove 2112, the movable straight groove 2111 and the movable arc groove 2112 are connected, and the third limiting ball 222 slides inside the movable straight groove 2111 in the initial position, which makes the third limiting ball 222 gradually slide from the movable straight groove 2111 to the movable arc groove 2112 as the movable sleeve 202 moves to the left. When the third limiting ball 222 slides into the movable arc groove 2112, under the limiting effect of the movable arc groove 2112, the second connecting rod 210 fixedly connected with the third limiting ball 222 will rotate in a small range, thereby driving the sealing plate 208 to rotate synchronously, and at this time the movable sleeve 202 also moves close to the inner wall of the preparation chamber 102. This setting is also to prevent the coating from entering the second cavity 217 in advance before the sealing plate 208 rotates.

[0043] Since a connecting hole 209 for connecting the preparation chamber 102 and the second chamber 217 is eccentrically provided on the sealing plate 208, when the sealing plate 208 rotates, the connecting hole 209 that is originally blocked will also be connected with the second chamber 217 under the rotation of the sealing plate 208. When the connecting hole 209 is connected with the second chamber 217, the negative pressure generated inside the second chamber 217 will be relieved, thereby sucking the paint near the inner wall of the preparation chamber 102 into the second chamber 217, so that this part of the paint can be fully mixed later.

[0044] See also Figure 8It can be seen that a limit slider is provided at one end of the rotating shaft 204 sliding inside the inner core rotating rod 203, and the structure of the limit slider is a square structure, and the slide groove opened inside the inner core rotating rod 203 is also a square structure. Therefore, when the inner core rotating rod 203 rotates, the limit slider sliding inside the slide groove of the inner core rotating rod 203 will also rotate, thereby driving the rotating shaft 204 to rotate synchronously, and through this connection method, even if the moving sleeve 202 drives the inner core rotating rod 203 to move, the inner core rotating rod 203 will only slide on the rotating shaft 204, and will not affect the rotation of the inner core rotating rod 203 driven by the rotating shaft 204, and because a plurality of groups of mixing rods 206 for mixing are installed on the inner core rotating rod 203, when the paint enters the second cavity 217, the plurality of groups of mixing rods 206 arranged on the inner core rotating rod 203 will perform secondary mixing on the paint entering the second cavity 217 by rotating.

[0045] At the same time, since a first spring 207 is provided between the inner core rotating rod 203 and the rotating shaft 204 , this arrangement also ensures that the inner core rotating rod 203 can perform corresponding telescopic movement on the rotating shaft 204 .

[0046] When the paint enters the second cavity 217 and undergoes secondary mixing at the inner core rotating rod 203, the inner core rod 104 also changes from the downward moving state to the upward moving state, so that not only the moving sleeve 202 Figure 4 The second connecting rod 210 is driven to move rightward from the movable arc groove 2112 to the inside of the movable straight groove 2111. That is to say, the blocking plate 208 is reset and rotated to the initial position at this time, and the connecting hole 209 is blocked again. This setting is also to prevent the coating from being discharged from the second cavity 217 after the movable sleeve 202 is reset and moved. Moreover, when the inner core rod 104 moves upward, the movable rack 110 also moves upward, thereby driving the rotating gear 205 and the rotating shaft 204 to rotate in the opposite direction. Figure 6 The suction plate 212 moving to the right will rotate in the opposite direction of the rotating shaft 204. Figure 6 Direction leftward.

[0047] Since the movable sleeve 202 is Figure 4 When the suction plate 212 moves to the right, the blocking plate 208 will be driven to reset and rotate, thereby completing the blocking of the movable sleeve 202 again. Figure 6When the suction plate 212 moves to the left, it will be blocked again by the movable sleeve 202, and thus it cannot move effectively inside the sealed second cavity 217. For this reason, a movable plate 213 is movably sleeved on the rotating shaft 204, so that when the suction plate 212 moves to the left, the gas that should have been pushed to the first cavity 215 will be blocked again by the movable sleeve 202, thereby pushing the gas to the movable plate 213. Since a second spring 214 is provided between the movable plate 213 and the inner wall of the first cavity 215, the movable plate 213 will move the same as the suction plate 212 after being subjected to pressure, and squeeze the second spring 214. It should be noted that the elastic coefficient of the second spring 214 is relatively large. Before being subjected to the pressure generated by the leftward movement of the suction plate 212, the movable plate 213 will not move. This arrangement is also for the purpose that even if the movable sleeve 202 is closed again, the suction plate 212 will still have a certain distance to move.

[0048] At the same time, a limiting block 221 is also provided between the movable plate 213 and the suction plate 212. This arrangement can avoid direct contact between the movable plate 213 and the suction plate 212, limit the movable plate 213, and leave a certain space between the movable plate 213 and the suction plate 212, thereby preventing the suction plate 212 from blocking the connecting groove 216.

[0049] See also Figure 6 It can be seen that since a first discharge port 218 for discharging is provided at one end of the second cavity 217 close to the first cavity 215, a second discharge port 219 for discharging is also provided at the bottom of the mixing sleeve 201, and the first discharge port 218 and the second discharge port 219 are staggered, so that when the movable sleeve 202 moves to the left, the first discharge port 218 and the second discharge port 219 will be staggered, so that the inner wall of the mixing sleeve 201 blocks the first discharge port 218, and when the movable sleeve 202 moves to the right to the maximum position, the first discharge port 218 will be reset to the same position as the movable sleeve 202. The second discharge port 219 is connected to each other. When the first discharge port 218 and the second discharge port 219 are connected, the sealing of the internal cavity of the movable sleeve 202 will be released. At this time, the suction plate 212 compressed will move to the right to generate thrust, which will act on the first cavity 215 through the connecting groove 216, and then effectively discharge the paint temporarily stored in the second cavity 217 from the first discharge port 218 and the second discharge port 219 to the outside of the mixing sleeve 201, so that the high speed near the mixing rod 103 can further mix this part of the paint again.

[0050] This process is repeated repeatedly. Finally, when the paint is mixed, the user can open the discharge port at the bottom of the preparation tank 1 to discharge the mixed paint out of the preparation tank 1 .

[0051] In this embodiment, a moving rack 110 is provided on the inner core rod 104, and the moving rack 110 is meshed with a rotating gear 205 provided on the rotating shaft 204, so that when the inner core rod 104 reciprocates in the vertical direction inside the mixing rotating rod 103, the rotating shaft 204 will also rotate clockwise and counterclockwise in stages under the meshing between the moving rack 110 and the rotating gear 205; On one hand, the rotating shaft 204 is connected with a suction plate 212, so when the rotating shaft 204 rotates clockwise, it will drive the suction plate 212 to move right accordingly, so that the closed and opened movable sleeve 202 can effectively suck the paint away from one end of the mixing rotating rod 103 into the interior of the movable sleeve 202; On the other hand, since the rotating shaft 204 also forms a sliding connection with the inner core rotating rod 203, and the rotating shaft 204 will drive the inner core rotating rod 203 to rotate synchronously, when the paint is sucked into the movable sleeve 202, the rotating shaft 204 drives the inner core rotating rod 203 to rotate, and the paint entering the movable sleeve 202 can also be rotated and mixed for the second time, thereby effectively improving the mixing degree of this part of the paint.

[0052] At the same time, when the inner core rod 104 drives the rotating shaft 204 to rotate counterclockwise, the compressed gas generated by the movement of the rotating shaft 204 can also allow the mixed paint to be discharged from the mixing sleeve 201, and then the high-speed rotation force near the mixing rotating rod 103 allows this part of the paint to be mixed and stirred again, thereby further improving the mixing degree of this part of the paint.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
