Description

Technical Field

[0001] This invention relates to a basalt three-dimensional grid inorganic grinding stone and its preparation process, belonging to the technical field of basalt inorganic grinding stone. Background Technology

[0002] Inorganic terrazzo uses inorganic materials (mainly cement) as its binder, in contrast to organic terrazzo which uses organic materials such as epoxy and polyurethane as binders. It is also known as "cement-based terrazzo" or "monolithic cast-in-place terrazzo." Its basic principle involves mixing aggregates (such as marble, granite, quartz, glass fragments, and seashells) with a colored cement matrix, spreading it on a concrete base, and then undergoing a series of processes including grinding, polishing, and sealing to ultimately form a seamless, robust, beautiful, and highly customizable artistic flooring.

[0003] Currently, cement and grinding stones are inexpensive and of good quality, but they are prone to cracking, and their thickness and porosity are relatively large, making them easy to stain during the grinding process and later use, reducing the stain resistance of inorganic grinding stones. Even after grinding, the porosity of basalt inorganic grinding stones is still difficult to repair effectively, which may lead to cracking problems after subsequent treatment, affecting the performance of inorganic grinding stones and reducing their service life. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a basalt three-dimensional mesh inorganic grinding stone and its preparation process.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a basalt three-dimensional grid inorganic grinding stone, comprising an inorganic grinding stone layer, characterized in that the inorganic grinding stone layer comprises a base layer, a three-dimensional grid layer and a basalt grinding stone layer, wherein the three-dimensional grid layer is laid on the base layer, and the basalt grinding stone layer is uniformly filled and cast within the three-dimensional grid layer.

[0006] A preparation process for a basalt three-dimensional mesh inorganic grinding stone, the preparation process comprising the following steps: (1) Basic ground treatment; (2) Lay out a three-dimensional grid; (3) Casting the inorganic grinding stone layer; (4) Polishing; (5) Sealing and curing; (6) Polishing; (7) Covering.

[0007] In this technical solution, step (1) involves construction on a solid, dense, clean, oil-free, and loose-particle-free concrete layer. The base layer compressive strength is ≥25MPa, and the height difference of the base layer plane within a 2-meter straightedge is ≤3mm. A heavy-duty grinder with diamond grinding discs is used for overall grinding to remove laitance and stains, open the pores, and then an industrial vacuum cleaner is used to thoroughly remove all dust. Cracks or pits are repaired with high-strength epoxy or polymer repair mortar. The base layer is kept fully moist but without standing water, and the base layer surface is in a saturated and surface-dry state until the next process. In this technical solution, in step (2), a metal spacer of appropriate size is selected as the base of the three-dimensional mesh layer. The three-dimensional mesh layer is fixed with an inorganic material so that it is firmly attached to the surface of the treated base layer. The top surface of the three-dimensional mesh layer is horizontal, firm, and the joints are tight.

[0008] In this technical solution, in step (3), an inorganic binder is first prepared for use. The cleaned and polished basalt is added to the inorganic binder according to the design ratio to obtain the grinding stone material. The mixture is thoroughly stirred by a mixing device to obtain the basalt grinding stone layer. The basalt grinding stone layer is filled and poured into the three-dimensional grid layer. After initial leveling, it is flattened and compacted with a large steel trowel to ensure that the material is tightly bonded to the base layer without voids. A heavy roller with a weight of more than 50 kg is used to repeatedly roll and squeeze out air bubbles, so that the surface is covered with slurry, ensuring that the aggregate is evenly distributed and does not sink.

[0009] In this technical solution, in step (4), a heavy-duty grinder is used to grind the inorganic grinding stone after it has been cured to remove the surface slurry. After grinding about 1 / 3 of the aggregate, it is initially leveled. Then, different specifications of grinding discs are used for grinding in sequence. After each grinding, the dust is thoroughly vacuumed and cleaned. The fineness of the grinding discs used for each grinding is gradually increased. After grinding, the surface of the inorganic grinding stone is repaired using a repair device.

[0010] In this technical solution, after the repair treatment in step (5), the surface of the inorganic grinding stone is cleaned, and after applying the curing agent, it is kept moist and left to stand for 24-48 hours.

[0011] In this technical solution, after the curing agent has fully reacted and dried in step (6), a polishing machine is used for final polishing so that the surface of the inorganic grinding stone reaches the designed gloss level.

[0012] In this technical solution, in step (7), a protective layer is applied to the surface of the treated inorganic grinding stone, preferably a water-based or solvent-based polyurethane sealant.

[0013] In this technical solution, the repair device in step (4) includes a bearing component and a repair component. The repair component is movably disposed at both ends of the bearing component. The bearing component includes a base plate. A mixing mechanism is fixedly installed on the top of the base plate. Multiple uniformly distributed high-definition cameras are fixedly connected to both ends of the bottom of the base plate. The repair component includes a rotating plate and an adjusting plate. The rotating plate is rotatably connected to the side end of the base plate. The side wall of the rotating plate is fixedly connected to a first electric push rod. The telescopic end of the first electric push rod is fixedly connected to the adjusting plate. A first scraper is fixedly installed at the bottom of the adjusting plate. The top surface of the base plate is rotatably connected to a second electric push rod, and the telescopic end of the second electric push rod is rotatably connected to the top of the rotating plate. A replenishment mechanism is fixedly installed at the bottom end of the rotating plate. A driving mechanism is fixedly installed on the side wall of the adjusting plate. A moving mechanism is fixedly installed on the bottom side wall of the adjusting plate. The moving mechanism is disposed below the driving mechanism.

[0014] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0015] The positive and progressive effects of this invention are as follows: The aforementioned basalt three-dimensional mesh inorganic terrazzo and its preparation process utilize basalt three-dimensional mesh inorganic terrazzo, with a thickness that can be as thin as one centimeter or even less. Compared to traditional inorganic terrazzo, it offers superior performance and is less prone to cracking, thus improving the overall effectiveness of the inorganic terrazzo. Basalt material is readily available and inexpensive, the preparation method is simple and construction is convenient, and its performance is 5-6 times higher than ordinary inorganic terrazzo. Furthermore, basalt inorganic terrazzo exhibits high wear resistance and scratch resistance, making it ideal for high-traffic areas. Its high compressive strength further enhances the overall structural strength of the terrazzo floor. It is chemically stable, does not react adversely with cement, and has superior resistance to acid and alkali corrosion compared to carbonate stones such as marble. Its high density, low porosity, and significantly lower water absorption rate than marble make it less prone to staining during grinding and subsequent use, offering better stain resistance. Sufficient repair treatment effectively reduces the porosity within the inorganic terrazzo, preventing future cracking and improving the overall strength of the basalt inorganic terrazzo.

[0027] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0028] like Figure 1-10 As shown, the basalt three-dimensional grid inorganic grinding stone includes an inorganic grinding stone layer 10, which includes a base layer 11, a three-dimensional grid layer 12, and a basalt grinding stone layer 13. The three-dimensional grid layer 12 is laid on the base layer 11, and the basalt grinding stone layer 13 is uniformly filled and cast in the three-dimensional grid layer 12.

[0029] A preparation process for a basalt three-dimensional mesh inorganic grinding stone, the preparation process comprising the following steps: (1) Basic ground treatment; (2) Lay out a three-dimensional grid; (3) Cast an inorganic grinding stone layer 10; (4) Polishing; (5) Sealing and curing; (6) Polishing; (7) Covering.

[0030] In step 1, the construction is carried out on a solid, dense, clean, oil-free, and loose-particle-free concrete layer. The compressive strength of the base layer 11 is ≥25MPa, and the height difference of the base layer 11 plane within a 2-meter straightedge is ≤3mm. A heavy-duty grinder with diamond grinding discs is used to grind the entire surface to remove laitance and stains, open the pores, and then use an industrial vacuum cleaner to thoroughly remove all dust. Cracks or pits are repaired with high-strength epoxy or polymer repair mortar. The base layer 11 is kept fully moist but without standing water, and the surface of the base layer 11 is in a saturated and surface-dry state until the next process.

[0031] In step 2, metal spacers of appropriate size are selected as the base of the three-dimensional mesh layer 12. The three-dimensional mesh layer 12 is fixed with inorganic materials to make it secure to the surface of the treated base layer 11, and the top surface of the three-dimensional mesh layer 12 is horizontal, firm, and the joints are tight.

[0032] In step 3, an inorganic binder is first prepared for later use. The cleaned and polished basalt is added to the inorganic binder according to the design ratio to obtain the grinding stone material. The mixture is thoroughly stirred by a mixing device to obtain the basalt grinding stone layer 13. The basalt grinding stone layer 13 is filled and poured into the three-dimensional grid layer 12. After initial leveling, it is flattened and compacted with a large steel trowel to ensure that the material is tightly bonded to the base layer 11 without voids. A heavy roller with a weight of more than 50 kg is used to repeatedly roll and press the material to squeeze out air bubbles and make the surface slurry to ensure that the aggregate is evenly distributed and does not sink.

[0033] In step 4, a heavy-duty grinder is used to grind the inorganic grinding stone after it has been cured to remove the surface slurry. After grinding about 1 / 3 of the aggregate, the surface is initially leveled. Then, different sizes of grinding discs are used in sequence for grinding. After each grinding, the surface is thoroughly cleaned by vacuuming. The fineness of the grinding discs used in each grinding is gradually increased. After grinding, the surface of the inorganic grinding stone is repaired using the repair device 20.

[0034] In step 5, after the repair treatment, the surface of the inorganic grinding stone is cleaned, a curing agent is applied, and it is kept moist for 24-48 hours.

[0035] In step 6, after the curing agent has fully reacted and dried, a polishing machine is used for final polishing to achieve the designed gloss level on the surface of the inorganic grinding stone.

[0036] In step 7, a protective layer is applied to the surface of the treated inorganic grinding stone. The protective layer is preferably a water-based or solvent-based polyurethane sealant.

[0037] The repair device 20 in step 4 includes a support component and a repair component. The repair component is movably disposed at both ends of the support component. The support component includes a base plate 21. A mixing mechanism is fixedly installed on the top of the base plate 21. The mixing mechanism stores repair slurry. The repair slurry has the same material and color as the inorganic grinding stone and is a high-flow material without aggregate. A steering mechanism is fixedly installed on all four sides of the base plate 21. A battery pack 23 located around the mixing mechanism is fixedly connected to the top of the base plate 21. Multiple evenly distributed high-definition cameras 24 are fixedly connected to both ends of the bottom of the base plate 21.

[0038] The mixing mechanism includes a tank 211, on the top of which a stirring motor 212 is fixedly installed. The output end of the stirring motor 212 is fixedly connected to a stirring shaft 213, and the stirring shaft 213 extends into the tank 211 and is fixedly connected to a stirring paddle 214. In this way, the repair slurry is stored in the tank 211, and the stirring motor 212 drives the stirring shaft 213 and the stirring paddle 214 to rotate, so as to achieve full mixing of the repair slurry and avoid solidification.

[0039] The steering mechanism includes a steering motor 22, a wheel seat 221, and a travel motor 222. The steering motor 22 is fixedly connected to the top of the base plate 21. The output end of the steering motor 22 is fixedly connected to the wheel seat 221. The side wall of the wheel seat 221 is fixedly connected to the travel motor 222. The output end of the travel motor 222 is fixedly connected to a roller. The roller is rotatably connected to the wheel seat 221. The steering motor 22 can drive the roller to adjust its direction, and the travel motor 222 can drive the roller to rotate to achieve movement of the repair device 20 in various directions.

[0040] The repair assembly includes a rotating plate 31 and an adjusting plate 41. The rotating plate 31 is rotatably connected to the side end of the base plate 21. The side wall of the rotating plate 31 is fixedly connected to a first electric push rod 311. The telescopic end of the first electric push rod 311 is fixedly connected to the adjusting plate 41. The top surface of the base plate 21 is rotatably connected to a second electric push rod 312, and the telescopic end of the second electric push rod 312 is rotatably connected to the top of the rotating plate 31. The telescopic movement of the second electric push rod 312 can drive the rotating plate 31 and the adjusting plate 41 to adjust their angles. The telescopic movement of the first electric push rod 311 can adjust the sliding of the adjusting plate 41.

[0041] A replenishment mechanism is fixedly installed at the bottom of the rotating plate 31. The replenishment mechanism includes a replenishment pipe 32, which is fixedly connected to the bottom of the rotating plate 31. The replenishment pipe 32 is connected to the bottom of the tank 211 through a delivery pipe 321. The delivery pipe 321 is located between the bottom plate 21 and the rotating plate 31. The bottom of the replenishment pipe 32 is provided with multiple evenly distributed branch pipes 322. Each branch pipe 322 is equipped with a solenoid valve, which is electrically connected to a high-definition camera 24. The repair agent is delivered to the replenishment pipe 32 through the delivery pipe 321. The high-definition camera 24 captures the situation of the area to be repaired and controls the corresponding solenoid valve to open the branch pipe 322, so that the repair agent is added to the area to be repaired.

[0042] The side wall of the adjusting plate 41 is provided with a T-shaped limiting rib 412. The limiting rib 412 is fitted and slides inside the rotating plate 31. The limiting rib 412 ensures the relative movement of the adjusting plate 41 and the rotating plate 31. A first scraper 411 is fixedly installed at the bottom of the adjusting plate 41. The first scraper 411 is used to uniformly repair the surface of the inorganic grinding stone. A conveying mechanism is fixedly installed at the bottom of the adjusting plate 41. The conveying mechanism includes a guide hood 42, which is fixedly installed at the bottom of the adjusting plate 41. The guide hood 42 is correspondingly arranged on one side of the replenishment pipe 32. An L-shaped structure is attached to the side wall of the guide hood 42. The baffle 421 is distributed correspondingly to the bottom of the guide shroud 42. The side wall of the baffle 421 is provided with a slot 422. The side wall of the guide shroud 42 is threadedly connected to a knob 423, and the knob 423 is located inside the slot 422. The guide shroud 42 is connected to the bottom of the tank 211 through a pipe. The baffle 421 is fixed by adjusting the height of the baffle 421 and tightening it with the knob 423. The gap between the baffle 421 and the bottom of the guide shroud 42 can control the speed of the repair slurry discharge, thereby making the repair slurry evenly delivered to the surface of the inorganic grinding stone and evenly spread by the first scraper 411.

[0043] A drive mechanism is fixedly installed on the side wall of the adjustment plate 41. The drive mechanism includes a drive motor 43 and a swing rod 431. The drive motor 43 is fixedly connected to the side wall of the adjustment plate 41, and the output end of the drive motor 43 is fixedly connected to the swing rod 431 with a U-shaped structure.

[0044] A moving mechanism is fixedly installed on the bottom side wall of the adjusting plate 41. The moving mechanism is located below the driving mechanism. The moving mechanism includes a track 44, which is fixedly connected to the bottom of the adjusting plate 41. A slider 441 is slidably connected to the track 44. The top of the slider 441 is rotatably connected to a movable plate 442. The side wall of the slider 441 is fixedly connected to a connecting block 443. The track 44 has an elongated hole for the movement of the connecting block 443 and the slider 441. The movable plate 442 is connected to the connecting block 443 via a spring 444. A second scraper 445 is fixedly connected to the bottom of the movable plate 442. The swing rod 431 is located between the movable plate 442 and the adjusting plate 41. A lead screw 446 is rotatably connected to the track 44. The lead screw 446 is threadedly connected to the slider 441. The side wall of the adjusting plate 41 is fixedly connected to an adjusting motor 447, and the output end of the adjusting motor 447 is fixedly connected to the lead screw 446. Next, when the adjusting motor 447 drives the lead screw 446 to rotate, the slider 441 moves within the track 44. The slider 441 drives the connecting block 443 and the movable plate 442 to move synchronously. During the translation, the swing arm 431 is always located between the movable plate 442 and the adjusting plate 41. After the high-definition camera 24 determines the location that needs to be repaired, the movable plate 442 is adjusted to the corresponding position. Then, the drive motor 43 drives the swing arm 431 to rotate. When the swing arm 431 rotates, it pushes the movable plate 442 to rotate, so that the movable plate 442 drives the second scraper 445 to contact the ground. The first scraper 411 and the second scraper 445 contact the bottom surface at the same time, and the second scraper 445 fully compacts the repair agent to fill all pores and improve the compactness of the inorganic grinding stone. When no special repair is needed, the swing arm 431 returns to its original position, and the elasticity of the spring 444 drives the second scraper 445 to return to its original position, so that the repair treatment of each location is carried out only by the first scraper 411.

[0045] Specifically, after the initial grinding process, pores may exist between the basalt aggregate and the inorganic binder. Repair device 20 is used to address this. During treatment, the repair slurry in the tank is transported to the guide shroud 42 through a pipeline. After adjusting the position of the baffle 421, it is evenly distributed. The first scraper 411 then evenly compacts the repair slurry, filling the gaps. Due to the varying number of pores at different locations, the first scraper 411 alone cannot effectively compact the slurry, requiring multiple passes for repair, resulting in reduced repair efficiency and poorer results. At this time, the inorganic grinding stone surface is simultaneously treated by the second scraper 445, and at the same time, part of the slurry is transported to the designated area by the branch pipe 322. The first scraper 411 scrapes the slurry flat, and the second scraper 445 compacts the slurry into the gap. The repair effect is improved by the simultaneous treatment of the first scraper 411 and the second scraper 445. The pressure is adjusted by adjusting the angle of the rotating plate 31 and the height of the second scraper 455 through the adjusting plate 41, so that the repair slurry is fully filled into the gap, thereby improving the repair effect and avoiding cracking caused by pores in the later stage.

The protection scope of this invention is defined by the appended claims.
