The materials used for the tabletop include the following components in parts by weight: 190 - 210 parts by weight of gel coat resin, 1800 - 1885 parts by weight of solid materials, 1100 - 1300 parts by weight of epoxy resin 501A, 250 - 270 parts by weight of epoxy resin 501B, 60 - 70 parts by weight of resin foaming agent, 545 - 595 parts by weight of 191# resin, 180 - 210 parts by weight of 80FA soft resin, 150 - 200 parts by weight of alkali-free random glass fiber mat, 5 - 8 volume parts of accelerator cobalt naphthenate, 2 - 6 volume parts of curing agent methyl ethyl ketone peroxide; the corresponding relationship between parts by weight and volume parts is g / mL. The manufacturing process includes the following steps: (1) Clean the mold for manufacturing the stone-like lightweight outdoor furniture tabletop and place the mold on a clean and flat workbench; (2) Weigh 190 - 210 parts by weight of gel coat resin and 0.5 - 1 volume part of accelerator cobalt naphthenate, stir well, then add 0.5 - 1 volume part of curing agent methyl ethyl ketone peroxide, mix evenly, pour into the mold and scrape flat with a rubber squeegee; (3) Prepare 450 - 500 parts by weight of solid materials according to the ratio, then add 230 - 250 parts by weight of 191# resin, 75 - 85 parts by weight of 80FA soft resin, 2.0 - 3.5 volume parts of accelerator cobalt naphthenate and 0.5 - 3 parts by weight of methyl ethyl ketone peroxide, mix evenly, pour into the mold and scrape flat with a rubber squeegee; (4) Place 75 - 100 parts by weight of alkali-free random glass fiber mat and pat with a rubber squeegee for 3 - 10 minutes; (5) Prepare another 450 - 500 parts by weight of solid materials according to the ratio, then add 230 - 250 parts by weight of 191# resin, 75 - 85 parts by weight of 80FA soft resin, 2.0 - 3.5 volume parts of accelerator cobalt naphthenate and 0.5 - 3 parts by weight of methyl ethyl ketone peroxide, mix evenly, pour into the mold and scrape flat with a rubber squeegee; (6) Place 75 - 100 parts by weight of alkali-free random glass fiber mat and pat with a rubber squeegee for 3 - 10 minutes; (7) Prepare 170 - 185 parts by weight of solid materials, 85 - 95 parts by weight of 191# resin, 30 - 40 parts by weight of 80FA soft resin, 0.5 - 1.5 volume parts of accelerator cobalt naphthenate and 0.5 - 3 parts by weight of methyl ethyl ketone peroxide according to the ratio, mix evenly, and evenly apply a layer along the vertical edge of the mold with a spatula; (8) Weigh 700 parts by weight of pre-mixed and pre-prepared solid materials, 1100 - 1300 parts by weight of epoxy resin 501A, 250 - 270 parts by weight of epoxy resin 501B, and 60 - 70 parts by weight of resin foaming agent, stir well, and pour into the mold; (9) Close the back mold and apply static pressure for 2.5 hours; (10) Demold, after applying static pressure for 72 hours, trim, repair, and color the product, and finally spray a layer of penetrating anti-fouling agent on its surface.It can be seen that a large variety of materials are used in the production process. However, in actual desktop production, the above-mentioned various raw materials are required, resulting in high production costs. But upon actual consideration, it can be found that it is not necessarily necessary to fill the interior with the above-mentioned materials.

[0003] Moreover, in the production process of artificial stone slabs and cement desktops, due to factors such as improper transportation or production operations, there are sometimes a certain number of defective products. At this time, the products need to be remelted as waste materials. For large-area table tops, they need to be broken and reused to save raw materials and reduce costs. At present, in the selection of raw materials for producing artificial stone slabs and cement desktops, it is not limited to traditional conventional materials such as cement. For example, fly ash refers to the fine ash captured from the flue gas after coal combustion and is the main solid waste discharged from coal-fired power plants. After the fly ash is recovered and processed, it can be applied to industrial production such as concrete or brick making.

[0004] Therefore, the main inventive purpose of this technical solution is to use recycled waste edge materials and fly ash to make table tops. Summary of the Invention

[0045] The following will specifically describe the implementation manners of the present invention in detail, so as to fully understand how the present invention uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0046] Refer to Figure 1 , a method for manufacturing a tabletop using fly ash and recycled waste edge materials. Among them, the tabletop includes an outer housing 100, an inner core 200 and a sealing surface 300. The inner core 200 is composed of fly ash mixed with recycled stone waste edge materials. This process includes the following steps:

[0047] a. Processing recycled stone edge materials:

[0048] a1. Removing impurities from the recycled waste stone slabs to remove the impurities on their surfaces; here, a decontamination device is used for production, such as Figures 2 - 4As shown in the figure, the impurity removal device includes a frame, on which a hoisting mechanism for hoisting materials is installed. Below the hoisting mechanism, there is a grinding mechanism and a matching first top block 17. Moreover, to improve the stability of the construction operation, an elastic shock pad 19 is arranged on the outer surface of the first top block 17. The elastic shock pad 19 can provide structural support for the other side of the material to increase the contact depth between the grinding disc 1 and the material, thereby improving the impurity removal effect.

[0049] The grinding mechanism is connected to a first driving member 18 that drives it to move towards / away from the first top block 17. Here, the first driving member 18 uses a hydraulic cylinder; the grinding mechanism includes a grinding disc 1, a rotating motor 15 that drives the grinding disc 1 to rotate, and an eccentric motor 16 that drives the grinding disc 1 to rotate eccentrically. The grinding disc 1 includes a disc body 11. On one side surface of the disc body 11, there is a disc seat 12 for connecting to the eccentric motor 16, and on the other side surface, there are multiple clamp block groups 13 for installing grinding blocks 14. During use, the friction surface side of the grinding disc 1 faces the material and moves towards the material under the action of the first driving member 18. At the same time, the rotating motor 15 operates to drive the grinding disc 1 to rotate. Then, after the grinding disc 1 contacts and grinds the material, the eccentric motor 16 rotates to drive the grinding disc 1 to rotate eccentrically, thereby increasing the grinding surface; specifically in terms of the structure here, a structure with multiple grinding discs 1 can also be selected. For example, there are four grinding discs 1 arranged side by side; in the case of four grinding discs 1, compared with a single grinding disc 1, smaller-sized grinding discs 1 can be used for grinding, thereby reducing costs, and the grinding effect is more in place and fine.

[0050] Specifically, the grinding disc 1 includes a disc body 11. On one side surface of the disc body 11, there is a disc seat 12 for connecting to the eccentric motor 16, and on the other side surface, there are multiple clamp block groups 13 for installing grinding blocks 14. Each of the clamp block groups 13 is evenly distributed in two rings on the surface of the disc body 11. The detachable clamp block groups 13 are provided to install the grinding blocks 14, which facilitates the replacement of the grinding blocks 14. At the same time, double-ring grinding inside and outside is adopted to further improve the grinding and impurity removal effect.

[0051] a2. Crush the waste stone slabs after impurity removal to obtain waste stone edge materials; here, a crushing device is used for production, such as Figure 5 、 Figure 6 As shown in the figure, the crushing device is installed on the frame and receives the recycled table board after impurity removal conveyed by the above hoisting mechanism. After being transported in place, there is an impact hammer 2 and a matching second top block 23 below the hoisting mechanism. Among them, the impact hammer 2 is also connected to a second driving member 24 that drives it to move towards / away from the second top block 23. Here, the second driving member 24 uses a hydraulic cylinder. Multiple cylindrical support rollers 21 for support are arranged at the lower end of the impact hammer 2 to provide structural support for the heavy impact hammer 2;

[0052] Structurally, the impact hammer 2 is composed of a plurality of hammer bodies 22 arranged side by side. On the opposite sides of both the hammer body 22 and the second top block 23, crushing teeth 221 are provided. In this structure, the impact hammer 2 can form a single-row multi-point impact, thereby further improving the efficiency of the entire impact crushing. Among them, the crushing teeth 221 are correspondingly disposed on the end faces of the hammer bodies 22. The crushing teeth 221 are dot matrix convex structures with sharp end faces. During the crushing process, the impact hammer 2 and the second top block 23 located on both sides of the material can improve the crushing effect after adding the crushing teeth 221, so as to improve the overall crushing efficiency.

[0053] Structurally, the hoisting mechanism includes a boom 4 and a plurality of clamps 5 provided on the boom 4 for clamping materials. Among them, the upper end of the boom 4 is connected to the overhead crane in the factory building to lift the boom 4 and the materials thereon through the overhead crane. When clamping plate-shaped objects, the clamp 5 can adopt a traditional C-shaped clamp 5. In terms of equipment, through one-time clamping and then successively passing through the impurity removal device and the crushing device, this process can be carried out in an orderly manner without multiple material disassembly and assembly, and the production efficiency is high. Moreover, the clamp 5 can adopt the content in the applicant's prior application CN 217838106U, which has the function of changing from a horizontal state to a vertical state as the overhead crane runs after the table board is poured. During the working process of lifting after clamping, the operator only needs to control the clamp, which greatly reduces the labor intensity of the operator and also simplifies the handling process.

[0054] Meanwhile, in order to improve the operation stability of the impurity removal and crushing devices, a clamping roller assembly is further provided on the frame. The clamping roller assembly includes a pressure roller 3 and a frame body 31 for installing the pressure roller 3. The pressure roller 3 is opposite to the first top block 17 and the second top block 23 in position to clamp the material. Using the pressure roller 3 to clamp the material can provide an additional clamping force to the material during the impurity removal and crushing processes, ensuring the stable position of the material during the operation of the equipment and not easily shaking. Among them, both axial ends of the pressure roller 3 are installed on the frame body 31 through a plurality of buffer springs 32. Among them, after both axial ends of the pressure roller 3 are installed on a mounting seat 33, buffer springs 32 are arranged between the mounting seat 33 and the frame body 31, so that the pressure roller 3 has a certain extrusion force on the material, ensuring the stable position of the material, without shaking or angular deviation that will affect the crushing and impurity removal effects. At the same time, when the impact hammer 2 acts, the stability of the material is ensured, and there will be no large-area crushing, so as to meet the requirement of forming the required small-size block structure by local crushing of the material, and also reduce the reaction force on the pressure roller 3 during the impact process, ensuring the service life of the clamping roller assembly.

[0055] b. Treat fly ash: The raw materials are dried and screened to obtain raw materials with uniform particles, and then piled up for standby;

[0056] c. Fabricate the tabletop housing 100: Take the raw materials for tabletop fabrication, stir them evenly, and then place them into a mold for molding to obtain the housing 100 with an intermediate placement groove. Among them, the above-mentioned raw materials can refer to the content shown in the applicant's prior application CN104957879 B, which will not be elaborated here.

[0057] d. Mix the edge materials obtained in step a and the fly ash obtained in step b in the housing 100 obtained in step c, and make the mixed edge materials and fly ash evenly distributed in the housing 100. This mixing process is carried out using a mixing device. As Figures 7 - 10 shown, a mixing platform 6 is provided on the frame. A housing 100 prefabricated in step c above is arranged on the mixing platform 6. Among them, a number of balls 61 for supporting the housing 100 are embedded on the surface of the mixing platform 6. In this structure, the housing 100 can easily move on the surface of the mixing platform 6 through the balls 61, which is more conducive to the initial installation and subsequent removal operations. A clamping mechanism 62 for clamping the housing 100 is provided on the mixing platform 6 on the periphery of the housing 100. A scraping mechanism 63 for leveling the materials is provided on the frame above the mixing platform 6. The clamping mechanism 62 includes ten chutes 621 evenly distributed on the mixing platform 6 and arranged in a circular array, and a plurality of cylindrical columns 622 respectively slidably connected to the chutes 621. Each column 622 is fixed to the chute 621 by bolts. Among them, the lower end of the column 622 is fixedly connected to a slider 623. The slider 623 is slidably connected to the chute 621. The slider 623 is located on the upper end surface of the chute 621. The column 622 extends out of the chute 621. A through hole for screwing is provided on the slider 623, and a fixing groove 624 parallel to it and used for fixing the slider 623 is provided on the edge of the chute 621. The position of the slider 623 is fixed in the fixing groove 624 by bolts and nuts.

[0058] Structurally, the scraping mechanism 63 includes sprocket groups 631 provided on both sides of the outer housing 100, a chain 632 wound around the two sprocket groups 631, and a plurality of scraping plates 633 with both ends fixedly connected to the chain 632 respectively. Under the cyclic movement of the chain 632, the lower end faces of the scraping plates 633 perform cyclic leveling operations on the materials inside the outer housing 100, and can continuously push the materials accumulated on one side of the outer housing 100, thereby ensuring that the materials after scraping are dispersed and have a consistent surface. Structurally, each of the scraping plates 633 is inclined; the inclinedly distributed scraping plates 633 can increase the contact with the materials as much as possible when scraping, and compared with the structure arranged vertically, the action during scraping is softer, the process of the scraping plate 633 pushing the materials is stable, and the structure operates more stably. Moreover, the lower end face of the scraping plate 633 is serrated. Structurally, the serrated structure of the lower end face of the scraping plate 633 can not only disperse and adjust the positions of the stone scraps mixed in the fly ash to avoid accumulation, but also form a plurality of groove structures on the surface of the materials after mixing, which is beneficial to mixing and forming with fluids such as cement after mixing, increasing the contact area, and improving the adhesion force.

[0059] Meanwhile, for the convenience of adjustment, the scraping mechanism 63 can be a structure that can be lifted and lowered. For example, it can be integrally arranged on a lifting frame 31 and adapted with relevant lifting motors, lifting cylinders and other structures and relevant transmission parts, so as to simply adjust the scraping depth.

[0060] This technical solution is used for the forming of table boards after the fly ash and stone scraps are mixed. After the two are mixed, they are directly mixed with fluids such as cement through the outer housing 100 and directly used for the forming of table boards. Therefore, during production, they are placed in the shape of the outer housing 100 after mixing, and no export operation is performed after mixing, which can ensure the uniformity of the components after mixing;

[0061] During use, according to different size requirements of the products, stone scraps and fly ash are placed in the outer housing 100, and then the scraping mechanism 63 is used to disperse and evenly distribute the materials in the outer housing 100. Compared with manual mixing, on the one hand, the labor intensity can be reduced. Workers only need to pick out the stone scraps with too large size differences and do not need to perform operations such as vigorously stirring; on the other hand, the materials after mixing can be directly used for production, greatly improving the production efficiency.

[0062] Also refer to Figure 11 、 Figure 12, compared with the above structure, the outer casing 100 is a circular structure as a whole. Accordingly, the scraping mechanism 63 can be changed to a rotating scraping form, that is, a rotating motor 634 is installed on the frame directly above the outer casing 100, and a scraper 633 is installed on the output shaft of the rotating motor 634. The structure of the scraper 633 is similar to that of the scraper 633 described above, but the installation position of the output shaft of the rotating motor 634 can be located within the end of the length direction of the scraper 633, so as to ensure that the scraper 633 at the rotation center position can also level the material.

[0063] During the mixing process, by setting an adjustable clamping mechanism 62, after placing the outer casing 100 on the mixing platform 6 during use, the annularly distributed columns 622 adjust their positions according to the different shapes of the outer casing 100, so that it can clamp the outer casing 100 of different shapes and sizes such as rectangular, square or circular, which has good versatility for the production of table boards of different sizes.

[0064] e. Prepare the table board sealing surface 300: Set up a template distributed around the circumference on the circumference of the product obtained in step d, take the raw materials for making the table top, stir evenly and pour them into it, scrape its surface flat, buckle the back mold, and apply static pressure for 2.5 - 5 hours;

[0065] f. Demold the product obtained in step e, trim, repair, and color the product after applying static pressure for 72 hours, and finally spray a layer of penetrating anti-fouling agent on its surface to obtain the table board.

[0066] At the same time, in the above step d, after the edge material is mixed with fly ash, a metal mesh layer 400 is set up on its upper surface. Setting up the metal mesh layer 400 can enable the material of the sealing surface 300 to gradually penetrate and fully contact with the fly ash and the edge material inside the outer casing 100, ensure the tight connection structure between the sealing surface 300, the outer casing 100 and the internal materials, and improve the structural stability of the formed table board.

[0067] This technical solution is improved on the basis of traditional artificial stone tabletops and cement tabletops. It adopts the process of preparing the outer casing 100, filling the edge material and fly ash on the basis of the outer casing 100, and forming after sealing, so that the inside of the table board product is filled with the edge material and fly ash, reducing the usage of materials such as resin currently used, greatly reducing the material cost. At the same time, it also recycles the waste stone produced in the production, realizes circular utilization, and cooperates with inexpensive fly ash as a filler. It not only has the same appearance as the usual table board products, but also does not cause a large increase in weight, and has the original advantages of light weight and easy transportation. The outer casing 100 and the sealing surface 300 are still produced from the original raw materials, and can also produce appearances such as imitation wood, imitation stone, and imitation iron according to requirements, while reducing costs and maintaining the original advantages of hard and wear-resistant surface, strong weather resistance, and strong corrosion resistance.

[0068] Although the present invention has been specifically shown and described in connection with preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined by the appended claims, and all such changes are within the scope of protection of the present invention.
