Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to a type of concrete with air purification function and its preparation method. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. Concrete is mainly composed of cementitious materials, aggregates, water, admixtures and additives in a certain proportion. After being uniformly mixed and stirred, it is compacted, molded, and cured to form an artificial stone. Concrete has the characteristics of abundant raw materials, low price and simple production process, and therefore it is widely used in various fields such as civil engineering, shipbuilding, machinery industry and geothermal engineering.

[0003] Currently, when concrete is used in housing construction, it releases harmful gases such as formaldehyde into the room due to the presence of large amounts of formaldehyde in interior decoration materials, such as plywood, blockboard, medium-density fiberboard, and particleboard. Concrete lacks air purification capabilities and cannot effectively purify indoor formaldehyde, resulting in slow formaldehyde dissipation and impacting people's health. Summary of the Invention

[0004] Therefore, the present invention provides a sterilizing faucet to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] According to a first aspect of the present invention, a concrete with air purification function includes cement, sand, ore powder, fly ash, aggregate and water, and also includes activated carbon powder. The weight parts of each component are: 12-16 parts cement, 6-10 parts sand, 2-5 parts ore powder, 5-10 parts fly ash, 40-44 parts aggregate, 7-9 parts water, and 5-10 parts activated carbon fiber. After the components are mixed and stirred, they are solidified in a mold to form a concrete block.

[0007] Furthermore, the upper surface of the concrete block has a groove filled with an adsorbent filler, and the outer surface of the concrete block is provided with an air purification coating.

[0008] Furthermore, the adsorbent filler comprises the following components: activated carbon particles, nanoemulsion binder, and waterproofing agent, with the following weight parts: 2-7 parts activated carbon particles, 0.1-0.2 parts nanoemulsion binder, and 0.1-0.3 parts waterproofing agent.

[0009] Furthermore, the air-purifying coating is formed by uniformly applying air-purifying paint to the surface of the concrete block and then curing it.

[0010] A method for preparing concrete with air purification function includes the following steps:

[0011] S1: Pour the specified weight parts of cement, sand, ore powder, fly ash, aggregate and water into the mixer and mix for 3-5 minutes at a mixing speed of 100-120 rpm;

[0012] S2: Sprinkle the activated carbon powder evenly into the product obtained in step S1, and stir again for 2-3 minutes at a stirring speed of 60-90 rpm.

[0013] S3: Transfer the product obtained in step S2 from the mixer to the mold, fill the mold cavity, tap the side wall of the mold to release air bubbles, and let it stand for 24 hours.

[0014] S4: Pour the specified weight parts of activated carbon granules, nano-emulsion binder and waterproofing agent into another mixer and mix for 3-5 minutes at a speed of 60-90 rpm.

[0015] S5: After the concrete has cured, obtain the concrete block, remove the formwork, take the concrete block out of the formwork, and turn it upside down;

[0016] S6: Fill the groove on the upper surface of the concrete block with the material obtained in step S1, and let it stand for 1 hour to solidify to form an adsorbent filler.

[0017] S7: Apply air purification coating evenly to the outer surface of concrete and adsorbent filler. After the coating cures, it forms an air purification coating layer.

[0018] Furthermore, the mold in S3 includes a mold base, with side plates on both sides of the upper surface of the mold base, a front plate on the front upper surface of the mold base, hinges connecting the bottom of the front plate and the side plates, a rear plate on the rear upper surface of the mold base, bolts penetrating the front plate and the rear plate, a fixing ring connecting the top center of the front plate, the rear plate and the side plates, a support rod on the top of the mold base, and a sliding groove on the rear side of the mold base.

[0019] Furthermore, a threaded hole is provided through the inside of the support rod, and threaded rods are connected to both sides of the support rod. A support fork is connected to the end of the threaded rod away from the support rod. There are two threaded rods, and the outer diameter of the threaded rod is adapted to the inner diameter of the threaded hole. The threaded rod is inserted into the threaded hole and forms a threaded connection with the support rod. The threads on the two threaded rods are in opposite directions.

[0020] Furthermore, a hinge seat is connected to the rear side wall of the rear plate, a U-shaped plate is provided on the rear side of the hinge seat, and a pin is provided through the middle of the hinge seat. The rear plate and the front plate are both connected to the two side plates by bolts, and the rear plate is rotatably connected to the U-shaped plate through the hinge seat and the pin.

[0021] Furthermore, a slider is connected to the bottom end of the U-shaped plate. The slider has an L-shaped cross-section and is integrally connected to the U-shaped plate. The slider is locked inside the groove and slidably connected to the mold base.

[0022] The present invention has the following advantages:

[0023] 1. This air-purifying concrete and its preparation method, by setting up grooves and adsorbent fillers, mixes and stirs activated carbon particles, nano-emulsion binders and waterproofing agents in another mixer in a specified weight proportion, and fills the grooves with the resulting mixture to form adsorbent fillers. The activated carbon particles adsorb harmful gases such as formaldehyde in the air, promote the rapid dissipation of formaldehyde in the room, and increase the air-purifying function of the concrete.

[0024] 2. This air-purifying concrete and its preparation method, by setting an air-purifying coating, involves uniformly applying air-purifying coating to the outer surface of the concrete block. After the coating cures, it forms an air-purifying coating that performs secondary purification of the indoor air. Furthermore, by increasing the contact area between the air-purifying coating and the air, it achieves the purpose of thoroughly purifying formaldehyde.

[0025] 3. This concrete with air purification function and its preparation method, by setting a back plate and a U-shaped plate, uses a mold to form the concrete. During the process, a slider slides in the groove, and the slider drives the back plate to slide back and forth on the mold base via the U-shaped plate, so as to adjust the width of the mold cavity. This makes the mold suitable for forming concrete of various sizes, thus increasing the applicability of the mold.

[0026] This concrete with air purification function and its preparation method, by setting up a support rod, rotates the support rod and drives two screws on both sides to move laterally through the internal screw hole, so that the two screws move towards the side away from the support rod. The screws use the support fork to apply a pushing force to the fixing ring, thereby causing the two side plates to be rotated around the pin shaft by the pushing force away from the inner cavity of the mold, so that the concrete block in the inner cavity of the mold is exposed, achieving the purpose of quickly driving the mold to open.

[0031] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0032] Example 1

[0033] like Figures 1 to 3 As shown, a concrete with air purification function in the first aspect embodiment of the present invention includes cement, sand, ore powder, fly ash, aggregate and water, and also includes activated carbon powder. The weight parts of each component are: 16 parts cement, 10 parts sand, 5 parts ore powder, 10 parts fly ash, 44 parts aggregate, 9 parts water, and 10 parts activated carbon fiber. After the components are mixed and stirred, they are solidified in a mold to form a concrete block 1.

[0034] Specifically, a groove 2 is provided on the upper surface of the concrete block 1. The groove 2 provides a filling space for the adsorbent filler 3. The groove 2 is filled with the adsorbent filler 3, which is used for initial air purification and absorption of harmful gases such as formaldehyde. An air purification coating 4 is provided on the outer surface of the concrete block 1. The air purification coating 4 is used for secondary purification of harmful gases and formaldehyde in the air, promoting the rapid dissipation of formaldehyde in the room and increasing the air purification function of the concrete.

[0035] Furthermore, the adsorbent filler 3 comprises the following components: activated carbon particles, nanoemulsion binder, and waterproofing agent. The weight parts of each component are: 7 parts activated carbon particles, 0.2 parts nanoemulsion binder, and 0.3 parts waterproofing agent. The activated carbon particles in the adsorbent filler 3 are used to adsorb harmful gases such as formaldehyde in the air. The nanoemulsion binder is used to tightly bond the activated carbon particles, and the waterproofing agent is used to waterproof the surface of the adsorbent filler 3.

[0036] Furthermore, the air purification coating 4 is formed by uniformly applying air purification paint to the surface of concrete block 1 and then curing it. The air purification paint performs secondary purification of the air in the house and increases the contact area between the air purification paint and the air, thereby achieving the purpose of thoroughly purifying formaldehyde.

[0037] A method for preparing concrete with air purification function includes the following steps:

[0038] S1: Pour the specified weight parts of cement, sand, ore powder, fly ash, aggregate and water into the mixer and mix for 3-5 minutes at a mixing speed of 100-120 rpm;

[0039] S2: Sprinkle the activated carbon powder evenly into the product obtained in step S1, and stir again for 2-3 minutes at a stirring speed of 60-90 rpm.

[0040] S3: Transfer the product obtained in step S2 from the mixer to the mold, fill the mold cavity, tap the side wall of the mold to release air bubbles, and let it stand for 24 hours.

[0041] S4: Pour the specified weight parts of activated carbon granules, nano-emulsion binder and waterproofing agent into another mixer and mix for 3-5 minutes at a speed of 60-90 rpm.

[0042] S5: After the concrete has cured, concrete block 1 is obtained. The formwork is removed, concrete block 1 is taken out of the formwork and turned upside down.

[0043] S6: Fill the groove 2 on the upper surface of the concrete block 1 with the material obtained in step S1, and let it stand for 1 hour to solidify to form the adsorbent filler 3;

[0044] S7: Apply air purification coating evenly to the outer surface of the concrete and the adsorbent filler 3. After the coating cures, it forms an air purification coating 4.

[0045] Specifically, the mold in S3 includes a mold base 5. The upper surface of the mold base 5 is provided with a punch corresponding to the groove 2 on the concrete block 1, used to form the groove 2 at the bottom of the concrete block 1. Side plates 6 are provided on both sides of the upper surface of the mold base 5. A front plate 7 is provided on the front upper surface of the mold base 5. Hinges 8 connect the bottom of the front plate 7 and the side plates 6. Both the front plate 7 and the side plates 6 are connected to the mold base 5 via hinges 8, enabling the front plate 7 and the side plates 6 to be flipped. A rear plate is provided on the rear upper surface of the mold base 5. 9. The rear plate 9 is used to adjust the width of the mold cavity. Bolts 10 are installed through both sides of the front plate 7 and the rear plate 9. The front plate 7 and the rear plate 9 are stably connected to the side plate 6 by the bolts 10 during concrete molding. The bolts 10 are loosened when the mold is disassembled. The front plate 7, the rear plate 9 and the side plate 6 are all connected to the top center of the top of the side plate 6 and the side plate 6. A support rod 12 is installed above the mold base 5. The extension and retraction of the support rod 12 applies a pushing force to the side plate 6, the front plate 7 and the rear plate 9 to drive the mold to disassemble quickly. A sliding groove 20 is opened on the rear side of the mold base 5.

[0046] Furthermore, a threaded hole 13 is provided through the support rod 12. Screws 14 are connected to both sides of the support rod 12. A support fork 15 is connected to the end of the screw 14 away from the support rod 12. The support fork 15 is C-shaped and connects to the screw 14. The support fork 15 is inserted into the fixing ring 11, allowing the screw 14 to act on the fixing ring 11 and restricting the screw 14 from rotating with the support rod 12. There are two screws 14, and the outer diameter of each screw 14 matches the inner diameter of the threaded hole 13. The screws 14 are inserted into the threaded hole 13 and form a threaded connection with the support rod 12. The two screws 14... The threads of the two screws are opposite in direction, and the threads at both ends of the screw hole 13 inside the support rod 12 are also opposite in direction. When the support rod 12 rotates, it drives the screws 14 on both sides to move in opposite directions. As the support rod 12 rotates, it drives the two screws 14 on both sides to move laterally through the screw hole 13 inside the support rod 12. This causes the two screws 14 to move toward the side away from the support rod 12. The screws 14 use the support fork 15 to apply a pushing force to the fixing ring 11, which in turn causes the two side plates 6 to be rotated around the pin shaft 18 by the pushing force away from the inner cavity of the mold, exposing the concrete block 1 in the inner cavity of the mold and achieving the purpose of quickly driving the mold to open.

[0047] Furthermore, a hinge seat 16 is connected to the rear side wall of the rear plate 9, and a U-shaped plate 17 is provided on the rear side of the hinge seat 16. The U-shaped plate 17 is used to connect the slider 19 and the rear plate 9. A pin 18 is provided through the middle of the hinge seat 16. The rear plate 9 and the front plate 7 are connected to the two side plates 6 by bolts 10 on both sides. The rear plate 9 is rotatably connected to the U-shaped plate 17 through the hinge seat 16 and the pin 18. When the support rod 12 applies a pushing force to the rear plate 9 through the pin 18, the rear plate 9 flips around the pin 18 to the rear side, which facilitates mold opening.

[0048] Furthermore, a slider 19 is connected to the bottom end of the U-shaped plate 17. The slider 19 has an L-shaped cross-section and is inserted into the groove 20. The slider 19 is integrally connected with the U-shaped plate 17 and is slidably connected to the mold base 5 inside the groove 20. By sliding the slider 19 in the groove 20, the slider 19 drives the rear plate 9 to slide back and forth on the mold base 5 via the U-shaped plate 17, thereby achieving the purpose of adjusting the width of the mold cavity. This allows the mold to be used for molding concrete of various sizes, increasing the applicability of the mold.

[0049] The usage method of this embodiment is as follows: When actually preparing concrete, the user first pours the specified weight of cement, sand, ore powder, fly ash, aggregate, and water into a mixer and mixes for 3-5 minutes. Then, evenly add activated carbon powder and continue mixing for 2-3 minutes. Then, adjust the position of the back plate 9 on the mold according to the required concrete block 1 size. By pulling the slider 19, it slides in the groove 20. The slider 19 drives the back plate 9 to slide back and forth on the mold base 5 via the U-shaped plate 17 to adjust the width of the mold cavity. After determining the position of the back plate 9, fix the back plate 9 by connecting the side plates 6 with bolts 10. Then, transfer the mixed material from the mixer to the mold, fill the mold cavity, and tap the side wall of the mold to remove air bubbles. Let it stand for 24 hours. Pour the specified weight of activated carbon particles, nano-emulsion adhesive, and waterproofing agent into another mixer and mix to form adsorbent filler 3. The mixing time is 3-5 minutes. After the concrete in the mold has solidified, concrete block 1 is obtained. Connect the support forks 15 at both ends of the support rod 12 to the top of the two side plates 6. The fixing ring 11 is inserted, and then the support rod 12 is rotated. The support rod 12 drives the two screws 14 to move laterally through the screw hole 13, so that the two screws 14 move toward the side away from the support rod 12. The screws 14 use the support fork 15 to apply a pushing force to the fixing ring 11, so that the two side plates 6 are pushed away from the inner cavity of the template and rotate around the pin 18. Then, the support forks 15 at both ends of the support rod 12 are inserted with the fixing ring 11 at the top of the front plate 7 and the rear plate 9. The above operation is repeated to push the front plate 7 and the rear plate 9 toward the side away from the inner cavity of the template. The concrete block 1 inside the mold cavity is fully exposed by flipping it over. Then, the concrete block 1 is removed from the mold and flipped upside down. At this time, the groove 2 is on the upper surface of the concrete block 1. Then, the adsorbent filler 3 is filled into the groove 2 on the upper surface of the concrete block 1. After standing for 1 hour, it is cured and formed. Finally, air purification coating is evenly applied to the outer surface of the concrete and the adsorbent filler 3. After the coating is cured, an air purification coating 4 is formed. The adsorbent filler 3 and the air purification coating 4 adsorb and purify harmful gases such as formaldehyde in the air.
