Description

Technical Field

[0001] The present application relates to the technical field of anti-corrosion paint production, and in particular to a high-thickness corrosion-resistant epoxy acrylic water-based anti-corrosion paint and a preparation device and process thereof. Background Art

[0002] High film thickness corrosion-resistant epoxy acrylic water-based anti-corrosion paint is an advanced coating technology that can effectively protect metal surfaces from corrosion. It has relatively high industrial value and is widely used in industrial facilities, bridges, ships, oil and gas pipelines and other places that require long-term anti-corrosion protection. Compared with traditional anti-corrosion paints, this anti-corrosion paint uses water as a solvent, has lower volatile organic compound (VOC) emissions, and has less impact on the environment.

[0003] The main method of making high film thickness corrosion resistant epoxy acrylic water-based anti-corrosion paint is to fully mix and stir raw materials such as epoxy acrylic resin, curing agent, additives, fillers and pigments through relevant stirring equipment, and then filter the mixed liquid to obtain the formed high film thickness corrosion resistant epoxy acrylic water-based anti-corrosion paint. Finally, the formed high film thickness corrosion resistant epoxy acrylic water-based anti-corrosion paint is poured into specific containers for transportation and sale.

[0004] In the above-mentioned related technologies, since the anti-corrosion paint is used as an item to protect metal accessories, the anti-corrosion paint needs to be de-aired during the production process to avoid the anti-corrosion paint from contacting with the air as much as possible, which may cause the anti-corrosion paint to deteriorate. However, when the high-film thickness corrosion-resistant epoxy acrylic water-based anti-corrosion paint in the stirring device is poured into a specific container, the anti-corrosion paint will still come into contact with the air, thereby reducing the production quality of the anti-corrosion paint.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-7, further details of this application are given. Example 1

[0037] A high-thickness corrosion-resistant epoxy acrylic water-based anticorrosive paint is prepared from the following ingredients: 60-100 kg of water-based epoxy acrylic emulsion, 12 kg of film-forming aid alcohol ester twelve, 0.8 kg of mildewcide, 12 kg of filler calcium carbonate, 15 kg of pigment titanium dioxide, 0.6 kg of thickener HEC hydroxyethyl cellulose, 1.2 kg of dispersant sodium lignin sulfonate, 0.5 kg of NXZ defoamer and 30 kg of deionized water.

[0038] The high film thickness corrosion-resistant epoxy acrylic water-based anti-corrosion paint in this embodiment is prepared by mixing other materials with deionized water as a solvent, which is more environmentally friendly than traditional oil-based paints. The present invention uses a high thickness film, which has higher wear resistance, and thus has a higher protection strength for the surface of mechanical equipment, thereby increasing the service life of the mechanical equipment. In addition, the present invention uses epoxy acrylic resin, which makes the anti-corrosion paint more viscous and not easy to fall off from the surface of mechanical equipment. Example 2

[0039] A preparation process of a high-thickness corrosion-resistant epoxy acrylic water-based anticorrosive paint comprises the following steps:

[0040] S1: The water-based epoxy acrylic emulsion, calcium carbonate, titanium dioxide and deionized water are fully and evenly stirred and mixed by a stirring device;

[0041] S2: adding the mixture into a grinder and grinding it, passing it through a 200-mesh sieve, and removing solid impurities in the mixture through a filtering device to obtain an anti-corrosion paint semi-finished product;

[0042] S3: adding alcohol ester twelve, mildew inhibitor, HEC hydroxyethyl cellulose, sodium lignin sulfonate and NXZ defoamer to the semi-finished anticorrosive paint obtained in S2, and mixing and stirring again by a stirring device to obtain a high film thickness corrosion-resistant epoxy acrylic water-based anticorrosive paint;

[0043] S4: Loading the formed high-thickness corrosion-resistant epoxy acrylic water-based anti-corrosion paint, and the loading device adopts the equipment device in Example 3. Example 3

[0044] A high film thickness corrosion resistant epoxy acrylic water-based anticorrosive paint preparation device, referring to Figure 1 and Figure 2 , including a stirring device body 1, a material receiving barrel 2, a switch component 4 and a detection component 5.

[0045] The stirring device body 1 is used to mix and stir the various materials in Example 1 to obtain a formed high-thickness corrosion-resistant epoxy acrylic water-based anti-corrosion paint. The side wall of the stirring device body 1 is connected to a discharge pipe 11. The part of the discharge pipe 11 connected to the stirring device body 1 and the end away from the stirring device body 1 are both made of metal. The middle part of the discharge pipe 11 is made of a hose to facilitate the position adjustment of the discharge pipe 11.

[0046] The material receiving barrel 2 is located on one side of the mixing equipment body 1 and below the discharge pipe 11. A feed port 21 is provided on the upper end surface of the material receiving barrel 2. A sealing connector 3 is provided between the discharge pipe 11 and the material receiving barrel 2. The sealing connector 3 is used for sealingly connecting the discharge pipe 11 and the feed port 21 on the material receiving barrel 2. A one-way gas valve 22 is provided on the peripheral wall of the material receiving barrel 2. The air outlet of the one-way gas valve 22 is toward the outside of the material receiving barrel 2. After the material receiving barrel 2 is filled with materials, the one-way gas valve 22 can prevent air from entering the material receiving barrel 2 as much as possible to contaminate the materials.

[0047] The switch component 4 is installed on the discharge pipe 11, and the switch component 4 can block or open the discharge pipe 11. When the sealing connection component 3 connects the discharge pipe 11 with the feed port 21 on the receiving barrel 2, the sealing connection component 3 can start the switch component 4, and the switch component 4 puts the discharge pipe 11 in an open state. When the sealing connection component 3 separates the discharge pipe 11 from the feed port 21 on the receiving barrel 2, the sealing connection component 3 puts the discharge pipe 11 in a blocked state through the switch component 4.

[0048] The detection component 5 is also installed on the discharge pipe 11. The detection component 5 is used to detect whether there is an air leakage between the discharge pipe 11 and the feed port 21 of the receiving barrel 2. When the discharge pipe 11 and the receiving barrel 2 are in a closed connection state, the switch component 4 makes the discharge pipe 11 always in an open state. When an air leakage occurs between the discharge pipe 11 and the discharge port on the receiving barrel 2, the detection component 5 can immediately start the switch component 4, and the switch component 4 makes the discharge pipe 11 in a closed state.

[0049] To sum up, the coordinated use of the sealing connector 3, the switch component 4 and the detection component 5 can ensure that the discharge pipe 11 and the upper feed port 21 of the receiving barrel 2 are always in a sealed state when connected, thereby minimizing the contact between the anti-corrosion paint and the air during the process of pouring the anti-corrosion paint into the container, which may cause the anti-corrosion paint to deteriorate, thereby improving the production quality of the anti-corrosion paint.

[0050] Among them, refer to Figure 3 and Figure 4 , the sealing connection member 3 in this embodiment is an outer tube 31.

[0051] The outer tube 31 is coaxially sleeved on the tail end of the discharge tube 11. The inner circumferential wall of the outer tube 31 is provided with an internal thread 311. The internal thread 311 is provided at the upper end and the lower end of the outer tube 31. The middle part of the inner circumferential wall of the outer tube 31 is a smooth surface. The outer circumferential wall of the discharge tube 11 is provided with a first external thread 111. The first external thread 111 on the discharge tube 11 (refer to Figure 5 ) is adapted to the internal thread 311 of the upper end part of the outer tube 31, and a material guide tube 23 is coaxially arranged at the discharge port of the material receiving barrel 2, and a second external thread 231 is arranged on the outer peripheral wall of the material guide tube 23, and the second external thread 231 on the material guide tube 23 is adapted to the internal thread 311 of the upper and lower end parts of the outer tube 31.

[0052] It should be noted that in actual use, the outer tube 31 is always in a threaded connection with the discharge pipe 11. When the discharge pipe 11 needs to be sealed and connected with the feed port 21 on the receiving barrel 2, the end of the outer tube 31 away from the discharge pipe 11 is made to face the upper end surface of the guide pipe 23, and then the outer tube 31 is rotated in the opposite direction. The outer tube 31 moves in a direction away from the discharge pipe 11, and the end of the outer tube 31 away from the discharge pipe 11 is threadedly connected to the guide pipe 23, and moves along the end close to the guide pipe 23. After the outer tube 31 and the guide pipe 23 are connected, the discharge pipe 11, the outer tube 31 and the guide pipe 23 are in a threaded connection and communication state in turn, thereby realizing the sealed connection between the discharge pipe 11 and the guide pipe 23, and then realizing the sealed connection between the discharge pipe 11 and the feed port 21 on the receiving barrel 2.

[0053] Secondly, refer to Figure 4 and Figure 5 The switch element 4 in this embodiment includes a blocking ring 41 and a blocking column 42 .

[0054] The sealing ring 41 is coaxially fixedly installed on the inner circumferential wall of the discharge pipe 11. Similarly, the sealing ring 41 is located at the tail end of the discharge pipe 11. The sealing column 42 is also located inside the discharge pipe 11 and is coaxially arranged with the discharge pipe 11. The side wall of the sealing column 42 is tightly pressed against the inner circumferential wall of the sealing ring 41. The end of the sealing column 42 away from the sealing ring 41 is fixedly connected with a connecting rod 43. In this embodiment, four connecting rods 43 are provided, and the four connecting rods 43 are evenly spaced around the axis of the sealing column 42. Of course, in other optional embodiments, the number of connecting rods 43 may be determined according to the specific situation.

[0055] One end of the connecting rod 43 away from the blocking column 42 is fixedly connected to the inner circumferential wall of the outer tube 31 , and the connection portion is located on the smooth surface of the inner circumferential wall of the outer tube 31 .

[0056] When the outer tube 31 seals and connects the discharge pipe 11 and the guide pipe 23, that is, the outer tube 31 moves in a direction away from the discharge pipe 11, the outer tube 31 drives the blocking column 42 to move in a direction away from the blocking ring 41 through the connecting rod 43 until the blocking column 42 is no longer in contact with the blocking ring 41, and the material in the mixing equipment body 1 flows into the receiving barrel 2 from the discharge pipe 11, the outer tube 31 and the guide pipe 23 in turn. When the receiving barrel 2 is filled, the outer tube 31 is reversed and moves in a direction close to the discharge pipe 11, thereby driving the blocking column 42 to move in a direction close to the blocking ring 41. When the outer tube 31 is just separated from the guide pipe 23 on the receiving barrel 2, the blocking column 42 also returns to the initial position and blocks the inner hole of the blocking ring 41 again, so that the material cannot flow out of the discharge pipe 11, thereby achieving the effect of the switch member 4 blocking or opening the discharge pipe 11 as a whole.

[0057] It should be noted that the upper end portion of the sealing column 42 in the present embodiment is made of rubber, and the fitting relationship between the sealing ring 41 and the sealing column 42 is an interference fit. On the one hand, since rubber has a certain elasticity, the rigid collision between the sealing column 42 and the sealing ring 41 is avoided as much as possible, thereby reducing the wear probability of the sealing column 42 and the sealing ring 41, and improving the service life of the sealing column 42 and the sealing ring 41; on the other hand, the interference fit between the sealing column 42 and the sealing ring 41 makes the outer peripheral wall of the sealing column 42 and the inner peripheral wall of the sealing ring 41 abut more closely, thereby avoiding material leakage and air entering the discharge pipe 11 as much as possible, thereby further ensuring the production quality of the anti-corrosion paint.

[0058] In order to further facilitate the abutment between the blocking column 42 and the blocking ring 41 when the blocking column 42 moves back, one end of the blocking column 42 close to the blocking ring 41 is set to be hemispherical, so as to facilitate the insertion of the blocking column 42 into the inner ring of the blocking ring 41.

[0059] In addition, refer to Figure 6 and Figure 7 The detection assembly 5 in this embodiment includes an inner tube 51 and a connecting ring 52.

[0060] The inner tube 51 is coaxially located inside the outer tube 31, and the outer peripheral wall of the upper end part of the inner tube 51 abuts against the inner peripheral wall of the discharge tube 11. The inner tube 51 and the outer tube 31 are connected by a connecting ring 52. The outer peripheral wall of the connecting ring 52 is fixedly connected to the inner peripheral wall of the outer tube 31, and the inner peripheral wall of the connecting tube is fixedly connected to the outer peripheral wall of the inner tube 51. When the outer tube 31 and the inner tube 51 are in the initial position, one end of the discharge tube 11 close to the connecting ring 52 abuts against the connecting ring 52.

[0061] Four slide grooves 511 are provided on the inner peripheral wall of the inner tube 51 in the vertical direction. The four slide grooves 511 correspond to the four connecting rods 43 one by one. The four slide grooves 511 are evenly spaced around the axis of the inner tube 51. A slider 53 is slidably arranged in each slide groove 511. One end of the connecting rod 43 close to the inner tube 51 is fixedly connected to the slider 53. One end of the slider 53 away from the blocking column 42 is fixedly connected to a return spring 54. The return spring 54 is located in the slide groove 511, and the other end of the return spring 54 is connected to the groove of the slide groove 511. The walls are fixedly connected, and the upper end of the slide groove 511 is separately provided with a through groove 512 connected to the space between the inner tube 51 and the outer tube 31. The through groove 512 in this embodiment is arranged in the horizontal direction, and an airbag 55 is arranged at the connection between the through groove 512 and the slide groove 511. After the airbag 55 is inflated, the airbag 55 is located in the slide groove 511 as a whole, and is in a block shape arranged in the vertical direction. The lower end surface of the airbag 55 after being inflated is in contact with the slider 53, and an inflatable part 56 for inflating the airbag 55 is provided on the outer peripheral wall of the inner tube 51.

[0062] It should be noted that, when the outer tube 31 in the present embodiment seals and connects the discharge tube 11 and the guide tube 23, the outer peripheral wall of the upper end portion of the inner tube 51 abuts against the inner peripheral wall of the discharge tube 11, and the outer peripheral wall of the lower end portion of the inner tube 51 abuts against the inner peripheral wall of the guide tube 23, that is, the outer tube 31, the inner tube 51, the discharge tube 11, the connecting ring 52 and the guide tube 23 together enclose a relatively closed space. Therefore, when the outer tube 31 moves in the direction close to the guide tube 23, it can be regarded as the guide tube 23 is inserted into the space between the outer tube 31 and the inner tube 51. When the guide tube 23 is inserted, the volume of the closed space is reduced. Therefore, the gas is compressed, and the gas enters the airbag 55 through the through groove 512. At the same time, the additional gas generated by the inflatable member 56 is also pressed into the airbag 55. The airbag 55 expands and squeezes the slider 53, and the slider 53 moves downward, and the return spring 54 is in a compressed state. State, the slider 53 drives the blocking column 42 downward through the connecting rod 43 during the downward movement, so that the blocking column 42 and the blocking ring 41 are in a separated state. If the closed space enclosed by the outer tube 31, the inner tube 51, the discharge pipe 11, the connecting ring 52 and the guide pipe 23 is deflated, it means that air has entered the discharge pipe 11, the inner tube 51 and the guide pipe 23, and the gas in the airbag 55 will flow out at this time, and the reset spring 54 resets and drives the slider 53 to move upward, thereby driving the blocking column 42 to move upward through the connecting rod 43, so that the blocking column 42 re-blocks the middle part of the blocking ring 41 to prevent the material in the discharge pipe 11 from being contaminated by air. When a certain period of time has passed, the staff finds that the receiving barrel 2 is not full, and they know that the sealing connector 3 is leaking, thereby achieving the effect of detecting the sealing between the discharge pipe 11 and the guide pipe 23.

[0063] Of course, in other optional embodiments, the detection results can be output in real time by installing an alarm or weighing the material receiving barrel 2, so as to facilitate timely maintenance work by the staff.

[0064] In order to further improve the sealing of the closed space, a sealing ring 6 is coaxially fixedly connected to the outer peripheral wall of the inner tube 51 in the present embodiment. Two sealing rings 6 are provided in the present embodiment, and the two sealing rings 6 are respectively located at the upper end and the lower end of the inner tube 51. The sealing ring 6 at the upper end is tightly pressed against the inner peripheral wall of the discharge pipe 11, and the sealing ring 6 at the lower end is tightly pressed against the inner peripheral wall of the guide pipe 23.

[0065] In order to ensure that the gas can smoothly enter the airbag 55 during the shrinkage of the enclosed space, a block 57 is provided on the groove wall of the slide groove 511. The block 57 is arranged in the horizontal direction and is located below the through groove 512. This is to prevent the slider 53 from squeezing the air inlet of the airbag 55 to be closed under the action of the return spring 54, thereby preventing the gas from entering the airbag 55, thereby ensuring the effective operation of the detection component 5.

[0066] Finally, the inflatable member 56 in this embodiment includes a mounting plate 561 and a sponge 562 .

[0067] The mounting plate 561 in this embodiment is set in an annular shape. The mounting plate 561 is coaxially fixedly mounted on the outer peripheral wall of the inner tube 51, and the mounting plate 561 does not abut against the outer tube 31. The sponge 562 is fixedly mounted on the lower end surface of the mounting plate 561. Dilute hydrochloric acid is stored in the sponge 562. The end of the guide tube 23 close to the sponge 562 is paved with marble 563 (refer to Figure 3 ).

[0068] When the guide tube 23 is slidably inserted into the space between the outer tube 31 and the inner tube 51, the upper end surface of the guide tube 23 will touch the sponge 562. At this time, the dilute hydrochloric acid in the sponge 562 will come into contact with the marble 563 on the upper end surface of the guide tube 23 to produce a chemical reaction and produce carbon dioxide. The volume of the closed space remains unchanged, and the gas in the space increases. Therefore, the gas enters the airbag 55 through the through groove 512 under the action of pressure, causing the airbag 55 to expand.

[0069] It should be noted that the corrosiveness of dilute hydrochloric acid is relatively small, and its corrosive effect on the sponge 562 can be ignored. Therefore, the sponge 562 can store a certain amount of dilute hydrochloric acid, so that it can contact with the marble 563 multiple times to produce carbon dioxide. After the specified number of contacts, when the material in the receiving barrel 2 is filled, dilute hydrochloric acid can be added to the sponge 562 again to ensure that the inflatable part 56 can stably produce gas.

[0070] In order to further ensure the stable operation of the inflatable member 56, chamfers are provided on one end of the outer tube 31 and the inner tube 51 close to the guide tube 23, and the chamfers on the outer tube 31 and the inner tube 51 are arranged in a direction away from each other, so as to avoid as much as possible that when the guide tube 23 is inserted into the space between the outer tube 31 and the inner tube 51, the marble 563 on the guide tube 23 collides with the outer tube 31 or the inner tube 51, causing the marble 563 to break and fall.

[0071] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
