Description

Technical Field

[0001] This invention relates to the field of flooring construction technology, and in particular to a method for constructing modified asphalt waterborne epoxy resin textured flooring. Background Technology

[0002] Modified asphalt waterborne epoxy resin textured flooring is a special functional flooring that combines the advantages of multiple materials. Modified asphalt provides excellent waterproofing, moisture resistance, and a certain degree of flexibility, while waterborne epoxy resin offers high strength, high adhesion, and excellent chemical corrosion resistance. The textured process provides strong anti-slip and matte finishes. It is widely used in places requiring excellent anti-slip, wear-resistant, waterproof, and corrosion-resistant properties, such as underground garage ramps, factory driveways, large parking lots, and toll booths.

[0003] To enhance the weather resistance and chemical corrosion resistance of the flooring and facilitate subsequent cleaning, a water-based epoxy coating is sprayed onto the surface of the roughened layer after its construction to form a topcoat. In existing technologies, high-pressure airless sprayers are mainly used for spraying water-based epoxy topcoats. During the spraying process, the operator needs to hold the spray gun and swing it left and right continuously to increase the spraying area. This puts a lot of strain on the arm and can easily lead to uneven thickness in some areas. Although some spraying equipment can increase the spraying area by connecting multi-nozzle extension tubes, these extension tubes cannot be stored in one unit. To avoid affecting the transportation of the spraying equipment, they can only be installed before use and disassembled after use, which is too inconvenient.

[0004] Therefore, it is necessary to invent a modified asphalt waterborne epoxy resin textured flooring construction method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a method for constructing modified asphalt waterborne epoxy resin textured flooring. The specialized spraying equipment used has a large spraying area. During the actual spraying process, it only needs to be pulled along the direction of the textured surface, reducing operational difficulty. Furthermore, after spraying, it can be easily stored as a single unit without frequent disassembly and reassembly of components, making it more convenient to use. This addresses the problem mentioned in the background art where, in the prior art, waterborne epoxy topcoat spraying mainly uses high-pressure airless sprayers. During spraying, the construction worker needs to continuously swing the spray gun left and right to increase the spraying area, which puts a heavy strain on the arm and easily leads to uneven thickness in certain areas. Although some spraying equipment can increase the spraying area by connecting multi-nozzle extension tubes, these extension tubes cannot be stored as a single unit. To avoid affecting the transportation of the spraying equipment, they must be installed before use and disassembled after use, which is extremely inconvenient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction method for modified asphalt waterborne epoxy resin textured flooring, wherein the modified asphalt waterborne epoxy resin textured flooring is composed of a concrete base layer, a waterborne epoxy modified asphalt primer layer, an intermediate mortar layer, a textured layer, and a waterborne epoxy topcoat layer arranged sequentially from bottom to top.

[0007] The construction method specifically includes the following steps:

[0008] S1. Use a grinder to grind the concrete base surface, remove laitance and impurities and open the concrete pores. Use an industrial vacuum cleaner to remove dust, and then fill cracks, pits and hollow areas with high-grade cement mortar.

[0009] S2. Mix components A and B of the waterborne epoxy modified asphalt primer in proportion and mix thoroughly with an electric mixer at low speed. Use a short-nap roller to evenly apply the mixed primer material to the concrete base layer and dry cure it under standard conditions to form a waterborne epoxy modified asphalt primer layer.

[0010] S3. Mix components A and B of the waterborne epoxy modified asphalt coating in proportion, stir evenly, add hard aggregate, stir with a mixer to form a paste mortar, and then use a trowel to evenly scrape the mortar onto the base layer to form the intermediate mortar layer.

[0011] S4. Before the paste mortar sets, use a textured roller to roll it on the mortar surface. When rolling, keep the roller perpendicular to the ground, apply even force and pull out the desired texture in one go. After the texture is completed, let the textured layer cure naturally to form a textured layer. Then use an industrial vacuum cleaner to clean the dust and loose particles on the surface of the textured layer.

[0012] S5. Mix components A and B of the water-based epoxy topcoat in proportion, stir evenly, and then add it to a special spraying equipment to spray onto the surface of the roughened layer to form a water-based epoxy topcoat.

[0013] The dedicated spraying equipment includes a moving component, a water-based epoxy coating supply component at the top of the moving component, a gear drive component at the bottom of the moving component, a flow-diverting spraying component at the front end of the moving component, and extension spraying components on both sides of the gear drive component and the flow-diverting spraying component. The gear drive component is used to drive the two sets of extension spraying components to unfold. After unfolding, the two sets of extension spraying components are aligned with the two output ends of the flow-diverting spraying component. The gear drive component drives the flow-diverting spraying component to complete the connection with the two sets of extension spraying components. The flow-diverting spraying component and the two sets of extension spraying components spray water-based epoxy topcoat onto the roughened layer together along the coaxial direction.

[0014] Preferably, the moving component includes a platform, and two wheel axles are rotatably nested at the bottom of the platform via bearings, with a moving wheel fixedly sleeved at both ends of the outer side of each wheel axle.

[0015] Preferably, a push-pull bracket is fixedly installed at the rear end of the top of the vehicle panel, a mounting beam is fixedly installed on the top inner side of the push-pull bracket, a control box is fixedly installed on the top of the mounting beam, and a touch screen is fixedly installed on the front of the control box.

[0016] Preferably, the water-based epoxy coating supply assembly includes a storage container, a plunger pump, and a rechargeable battery fixedly installed on the top of the vehicle panel. The input end of the plunger pump is fixedly connected to a coating suction pipe, which is connected to the output end of the storage container. The output end of the plunger pump is fixedly connected to a coating output pipe. The touch screen, the plunger pump, and the rechargeable battery are all electrically connected to the control box.

[0017] Preferably, the gear drive assembly includes a fixed plate fixedly disposed at the front end of the bottom of the vehicle plate. An electric push rod electrically connected to the control box is fixedly disposed on the back of the fixed plate. The output shaft of the electric push rod extends to the front of the fixed plate and is fixedly connected to an end plate. Two racks A are fixedly connected to the front of the end plate, and two guide shafts are fixedly connected to the back of the end plate. Each guide shaft penetrates the fixed plate and is slidably connected to the fixed plate through a linear bearing. A slider is slidably sleeved on the outer side of the two guide shafts through a linear bearing. Racks B are fixedly disposed on both sides of the slider. An elastic element fixedly connected between the end plate and the slider is sleeved on the outer side of each guide shaft.

[0018] Preferably, the diversion spraying assembly includes a fixed frame fixedly mounted on the front end of the vehicle panel. A diversion pipe fixedly mounted on the inner side of the fixed frame and fixedly connected to the paint output pipe is provided. Sealing rings are bonded and fixedly mounted at both ends of the diversion pipe. A spray head A is fixedly connected to the bottom of the diversion pipe. Rotary sleeves are provided at both ends of the outer side of the diversion pipe through bearings. A gear A that meshes with an adjacent rack A is fixedly mounted on the outer side of any one of the rotary sleeves. Multiple evenly distributed guide rods are uniformly fixedly mounted on the side of the rotary sleeves. A threaded sleeve screwed to the outer side of the diversion pipe is provided on the outer side of the multiple guide rods through linear bearings.

[0019] Preferably, any set of the extended spraying components includes a mounting shaft that is rotatably nested at the front end of the bottom of the vehicle panel via a bearing. A gear B and an extension plate are fixedly sleeved on the outer side of the mounting shaft from top to bottom. The gear B meshes with an adjacent rack B. An extension tube with a front opening is fixedly connected to the end of the extension plate. An external thread adapted to a threaded sleeve is provided at the front end of the outer side of the extension tube. Multiple spray nozzles B are uniformly fixedly connected to the bottom of the extension tube.

[0020] Preferably, S5 further includes:

[0021] S51. Add the well-stirred water-based epoxy topcoat into the storage container, and then start the electric push rod through the touch screen. After the electric push rod is started, it drives the end plate to move backward continuously. The backward movement of the end plate drives the gear A to rotate through the rack A. When the gear A rotates, it drives the rotating sleeve to rotate outside the diversion pipe. The rotating sleeve drives the threaded sleeve to rotate through the guide rod. When the threaded sleeve rotates, it moves outward along the diversion pipe.

[0022] S52. When the end plate moves backward, the slider is pushed by the elastic element. The slider drives the gear B to rotate through the rack B. The gear B drives the extension tube to rotate through the mounting shaft and the extension plate. As the extension tube rotates continuously, the end of the extension tube with the opening matches the end of the diverter tube. At this time, the slider is attached to the front of the fixed plate and blocked by the fixed plate.

[0023] S53. The end plate continues to move backward under the drive of the electric push rod. The elastic elements on the outside of the two guide shafts are compressed. At the same time, rack A continues to drive gear A to rotate until any threaded sleeve is screwed onto the outside of the diverter pipe and the adjacent extension pipe to achieve a sealed connection between the diverter pipe and the extension pipe. At this time, the electric push rod is stopped and the power is cut off. Meanwhile, nozzle A and multiple nozzles B form a coaxial spraying assembly.

[0024] Preferably, S5 further includes:

[0025] S54. Start the plunger pump via the touch screen. After the plunger pump starts, it draws water-based epoxy coating from inside the storage container and then inputs it into the distribution pipe through the coating output pipe. A small amount of coating is sprayed onto the textured surface from nozzle A, and the remaining coating enters the two extension pipes from the two output ends of the distribution pipe, and is then sprayed onto the textured surface by multiple nozzles B.

[0026] S55. The car panel is pulled by the push-pull frame. The car panel moves through four wheel axles. During the movement of the car panel, the coaxial spraying assembly moves along the direction of the roughened surface, thereby achieving the spraying of the roughened surface to form a water-based epoxy coating.

[0027] Preferably, S5 further includes:

[0028] S56. After the spraying is completed, the plunger pump is stopped and the power is cut off. Then the electric push rod is started and the electric push rod drives the end plate forward to reset. As the end plate moves forward, the threaded sleeve moves from the outside of the shunt tube and the adjacent extension tube to the outside of the shunt tube again. Then the extension tube is stored in the bottom side of the vehicle plate again.

[0029] The technical effects and advantages of this invention are as follows:

[0030] This invention features a dedicated spraying device that allows two sets of extended spraying components to be deployed via a gear drive assembly before the application of water-based epoxy topcoat. These extended spraying components then mate with the two ends of a split spraying assembly. The gear drive assembly then drives the split spraying assembly to connect with the two extended spraying components, forming a coaxial spraying assembly. Compared to existing technologies, this invention offers a significantly larger spraying area. During actual spraying, it only requires pulling along the direction of the roughened surface, reducing operational difficulty. Furthermore, after spraying, it can be easily stored as a single unit without frequent disassembly and reassembly, making it more convenient to use. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This invention provides, for example Figure 1 The method for constructing a modified asphalt waterborne epoxy resin textured floor is shown. The modified asphalt waterborne epoxy resin textured floor consists of a concrete base layer, a waterborne epoxy modified asphalt primer layer, an intermediate mortar layer, a textured layer, and a waterborne epoxy topcoat layer arranged from bottom to top.

[0041] The construction method specifically includes the following steps:

[0042] S1. Use a grinder to grind the concrete base surface, remove laitance and impurities and open the concrete pores. Use an industrial vacuum cleaner to remove dust, and then fill cracks, pits and hollow areas with high-grade cement mortar.

[0043] S2. Mix components A and B of the waterborne epoxy modified asphalt primer in proportion and mix thoroughly with an electric mixer at low speed. Use a short-nap roller to evenly apply the mixed primer material to the concrete base layer and dry cure it under standard conditions to form a waterborne epoxy modified asphalt primer layer.

[0044] S3. Mix components A and B of the waterborne epoxy modified asphalt coating in proportion, stir evenly, add hard aggregate, stir with a mixer to form a paste mortar, and then use a trowel to evenly scrape the mortar onto the base layer to form the intermediate mortar layer.

[0045] S4. Before the paste mortar sets, use a textured roller to roll it on the mortar surface. When rolling, keep the roller perpendicular to the ground, apply even force and pull out the desired texture in one go. After the texture is completed, let the textured layer cure naturally to form a textured layer. Then use an industrial vacuum cleaner to clean the dust and loose particles on the surface of the textured layer.

[0046] S5. Mix components A and B of the water-based epoxy topcoat in proportion, stir evenly, and then add it to a special spraying equipment to spray onto the surface of the roughened layer to form a water-based epoxy topcoat.

[0047] The present invention also provides, for example Figures 2-7The diagram shows a special spraying device for implementing the above-mentioned construction method, including a moving component 1, a water-based epoxy coating supply component 2 at the top of the moving component 1, a gear drive component 3 at the bottom of the moving component 1, a diversion spraying component 4 at the front end of the moving component 1, and extension spraying components 5 on both sides of the gear drive component 3 and the diversion spraying component 4. The gear drive component 3 is used to drive the two sets of extension spraying components 5 to unfold. After unfolding, the two sets of extension spraying components 5 are aligned with the two output ends of the diversion spraying component 4. The gear drive component 3 drives the diversion spraying component 4 to complete the connection with the two sets of extension spraying components 5. The diversion spraying component 4 and the two sets of extension spraying components 5 spray water-based epoxy topcoat on the roughened layer together in the coaxial direction.

[0048] like Figure 4 As shown, the mobile component 1 includes a platform 11 made of Q235 carbon steel, which has high strength and load-bearing capacity and can stably support heavy objects such as the storage container 21 and the plunger pump 22. Two wheel axles 12 are nested at the bottom of the platform 11 through bearings. Each wheel axle 12 has a moving wheel 13 fixedly sleeved at both ends on its outer side. A push-pull frame 14 is fixedly installed at the rear end of the top of the platform 11. A mounting beam 15 is fixedly installed on the top inner side of the push-pull frame 14. Both the push-pull frame 14 and the beam are made of Q235 carbon steel and are welded together, resulting in a strong structural rigidity and no shaking when pushed or pulled. A control box 16 is fixedly installed on the top of the mounting beam 15. The control box 16 has a built-in PLC controller and a touch screen 17 is fixedly installed on the front of the control box 16.

[0049] By setting up the above structure, the start and stop of the plunger pump 22 and the electric push rod 32 and the driving direction can be controlled by the touch screen 17. In addition, after the plunger pump 22 is started, the vehicle plate 11 can be pulled by the push-pull bracket 14, thereby causing the vehicle plate 11 to move through the four wheel axles 12. During the movement of the vehicle plate 11, the coaxial spraying assembly is driven to move along the roughened surface setting direction, thereby realizing the spraying of the roughened surface to form a water-based epoxy surface coating.

[0050] like Figure 4 As shown, the waterborne epoxy coating supply assembly 2 includes a storage container 21 fixedly mounted on the top of the vehicle panel 11, a plunger pump 22, and a rechargeable battery 23. The storage container 21 has a movable top cover. When adding waterborne epoxy topcoat, the top cover is opened, and after adding, the top cover is closed to prevent foreign objects from falling into the storage container 21 and causing contamination of the waterborne epoxy topcoat. The input end of the plunger pump 22 is fixedly connected to a paint suction pipe 24, which is connected to the output end of the storage container 21. The output end of the plunger pump 22 is fixedly connected to a paint output pipe 25. The touch screen 17, the plunger pump 22, and the rechargeable battery 23 are all electrically connected to the control box 16.

[0051] By setting up the above structure, the water-based epoxy topcoat that has been stirred evenly can be added into the storage container 21. When the plunger pump 22 is started, the plunger pump 22 draws the water-based epoxy topcoat inside the storage container 21 and then inputs it into the diversion pipe 42 through the paint output pipe 25.

[0052] like Figure 5 As shown, the gear drive assembly 3 includes a fixed plate 31 fixedly mounted on the bottom front end of the vehicle plate 11. An electric push rod 32 electrically connected to the control box 16 is fixedly mounted on the back of the fixed plate 31. The output shaft of the electric push rod 32 extends to the front of the fixed plate 31 and is fixedly connected to an end plate 33. Two racks A34 are fixedly connected to the front of the end plate 33, and two guide shafts 35 are fixedly connected to the back of the end plate 33. Each guide shaft 35 passes through the fixed plate 31 and is slidably connected to the fixed plate 31 through a linear bearing. A slider 37 is slidably sleeved on the outer side of the two guide shafts 35 through a linear bearing. Racks B38 are fixedly mounted on both sides of the slider 37. An elastic element 36 is sleeved on the outer side of each guide shaft 35 and fixedly connected between the end plate 33 and the slider 37. The elastic element 36 is a spring made of 65Mn spring steel, which has good elastic recovery and no permanent deformation after repeated compression.

[0053] By setting up the above structure, when the electric push rod 32 starts and drives the end plate 33 to move backward, the end plate 33 drives the two racks A34 to move backward synchronously, and at the same time drives the slider 37 to move backward through the two guide shafts 35. When the slider 37 moves backward, it drives the two racks B38 to move backward synchronously. When the rack A34 moves backward, it drives the adjacent gear A45 to rotate, and when the rack B38 moves backward, it drives the adjacent gear B52 to rotate.

[0054] like Figure 6 As shown, the diversion spraying assembly 4 includes a fixed frame 41 fixedly installed at the front end of the vehicle plate 11. A diversion pipe 42 fixedly installed inside the fixed frame 41 and fixedly connected to the paint output pipe 25 is provided. Both ends of the diversion pipe 42 are bonded with sealing rings made of fluororubber, which have good sealing effect and are corrosion resistant. A nozzle A43 is fixedly connected to the bottom of the diversion pipe 42. Both ends of the diversion pipe 42 are provided with rotating sleeves 44 through bearings. A gear A45 that meshes with the adjacent rack A34 is fixedly sleeved on the outside of any rotating sleeve 44. Multiple evenly distributed guide rods 46 are evenly fixedly connected to the side of the rotating sleeve 44. Threaded sleeves 47 that are screwed to the outside of the diversion pipe 42 are slidably sleeved on the outside of the multiple guide rods 46 through linear bearings.

[0055] By setting up the above structure, when the rack A34 drives the gear A45 to rotate, the gear A45 drives the rotating sleeve 44 to rotate outside the diverter tube 42. When the rotating sleeve 44 rotates, it drives multiple guide rods 46 to rotate synchronously. The multiple guide rods 46 then drive the threaded sleeve 47 to rotate synchronously outside the diverter tube 42. Since the threaded sleeve 47 is screwed to the diverter tube 42, as the threaded sleeve 47 rotates continuously, it first moves closer to the output end of the diverter tube 42. After the diverter tube 42 and the extension tube 54 are in contact, it continues to rotate to the outside of the extension tube 54 to achieve a sealed connection between the diverter tube 42 and the extension tube 54, thus preventing leakage of the pressurized paint or shaking of the extension tube 54 during subsequent transmission.

[0056] like Figure 7 As shown, any set of extended spraying components 5 includes a mounting shaft 51 that is nested at the bottom front end of the vehicle plate 11 via a bearing. Gear B52 and extension plate 53 are fixedly sleeved on the outside of the mounting shaft 51 from top to bottom. Gear B52 meshes with the adjacent rack B38. Extension plate 53 is made of 6061 aluminum alloy, which is lightweight, rigid, corrosion-resistant and not easy to rust. Extension tube 54 with a front opening is fixedly connected to the end of extension plate 53. The front end of extension tube 54 is provided with an external thread that matches the threaded sleeve 47. Multiple spray nozzles B55 are evenly fixedly connected to the bottom of extension tube 54.

[0057] By setting up the above structure, when gear B52 is driven to rotate by rack B38, gear B52 drives mounting shaft 51 to rotate. Mounting shaft 51 then drives extension tube 54 to rotate around mounting shaft 51 via extension plate 53. This causes extension tube 54 to drive multiple nozzles B55 to extend outward from the bottom side of vehicle plate 11 until the open end of extension tube 54 is in contact with the output end of diverter tube 42, providing the prerequisite for the sealing connection of subsequent threaded sleeve 47. After the coating enters the interior of diverter tube 42, under the diversion action of diverter tube 42, the coating flows from the interior of diverter tube 42 to the interior of two extension tubes 54, and is then sprayed onto the roughened surface by nozzle A43 and multiple nozzles B55. Since nozzle A43 and multiple nozzles B55 are coaxially arranged and equally spaced, the spraying of water-based epoxy coating can be achieved relatively uniformly.

[0058] like Figures 2-7 As shown, the working process of the above-mentioned special spraying equipment is as follows:

[0059] S51. Add the well-stirred water-based epoxy topcoat into the storage container 21. Then, start the electric push rod 32 through the touch screen 17. After the electric push rod 32 is started, it drives the end plate 33 to move backward continuously. The backward movement of the end plate 33 drives the gear A45 to rotate through the rack A34. When the gear A45 rotates, it drives the rotating sleeve 44 to rotate outside the diversion pipe 42. The rotating sleeve 44 drives the threaded sleeve 47 to rotate through the guide rod 46. When the threaded sleeve 47 rotates, it moves outward along the diversion pipe 42.

[0060] When the end plate 33 moves backward, it pushes the slider 37 through the elastic element 36. The slider 37 drives the gear B52 to rotate through the rack B38. The gear B52 drives the extension tube 54 to rotate through the mounting shaft 51 and the extension plate 53. As the extension tube 54 rotates continuously, the end of the extension tube 54 with an opening matches the end of the diversion tube 42. At this time, the slider 37 is attached to the front of the fixing plate 31 and blocked by the fixing plate 31.

[0061] S53 and end plate 33 continue to move backward under the drive of electric push rod 32. The elastic elements 36 on the outside of the two guide shafts 35 are compressed. At the same time, rack A34 continues to drive gear A45 to rotate until any threaded sleeve 47 is screwed on the outside of the diversion pipe 42 and the adjacent extension pipe 54 to achieve a sealed connection between the diversion pipe 42 and the extension pipe 54. At this time, the electric push rod 32 is stopped and the power is cut off. At the same time, nozzle A43 and multiple nozzles B55 form a coaxial spraying assembly.

[0062] S54. Start the plunger pump 22 via the touch screen 17. After the plunger pump 22 starts, it draws water-based epoxy coating from the storage container 21. Then, it is input into the diversion pipe 42 through the coating output pipe 25. A small amount of coating is sprayed onto the textured surface by the nozzle A43. The remaining coating enters the two extension pipes 54 from the two output ends of the diversion pipe 42, and is then sprayed onto the textured surface by multiple nozzles B55.

[0063] S55. The car panel 11 is pulled by the push-pull bracket 14. The car panel 11 moves through four wheel axles 12. During the movement of the car panel 11, the coaxial spraying assembly moves along the roughened surface setting direction, thereby realizing the spraying of the roughened surface to form a water-based epoxy surface coating.

[0064] S56. After the spraying is completed, the plunger pump 22 is stopped and the power is cut off. Then the electric push rod 32 is started and the electric push rod 32 drives the end plate 33 to move forward and reset. As the end plate 33 moves forward, the threaded sleeve 47 moves again from the outside of the diversion pipe 42 and the adjacent extension pipe 54 to the outside of the diversion pipe 42. Then the extension pipe 54 is stored again on the bottom side of the vehicle plate 11.

[0065] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
