Description

Technical Field

[0001] This invention belongs to the field of flooring materials technology, specifically relating to corundum wear-resistant flooring materials and their production equipment. Background Technology

[0002] Flooring materials refer to specific materials used in ground construction, forming a decorative and functional floor layer through on-site spreading, pouring, or brushing. Common types of flooring materials include resin-based, cement-based, gypsum-based, and composite materials. Among them, corundum wear-resistant flooring material is a type of cement-based material, mainly composed of corundum, special cement, pigments, and special additives. It can improve the wear resistance, impact resistance, and heavy load-bearing capacity of concrete floors, and is widely used in projects such as factories, warehouses, runways, and docks.

[0003] Currently, the high moisture content of emery flooring materials makes them prone to absorbing water and clumping, resulting in relatively poor surface strength, wear resistance, flexural strength, and compressive strength. This makes them unable to meet various usage requirements and also reduces the stability and aesthetics of emery flooring materials during use.

[0004] Therefore, in response to the above-mentioned technical problems, it is necessary to provide abrasive-resistant flooring materials and their production equipment.

[0005] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a corundum wear-resistant flooring material and its production equipment, which can solve the problems of high moisture content and easy water absorption and clumping of corundum wear-resistant flooring materials.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0008] The corundum wear-resistant flooring material, by mass fraction, includes the following components: 40-50 parts corundum, 45-55 parts cement, 0.4-0.6 parts water-reducing agent, 2-3 parts silica fume, 0.03-0.5 parts inorganic pigment, and 0.5-1 parts precipitated barium sulfate;

[0009] The preparation method of the diamond abrasive wear-resistant flooring material includes the following steps: first, sieve the diamond abrasive particle size and control the moisture content; premix the diamond abrasive and cement in a reactor, stirring at a speed of 1500 r / min for 15 minutes; heat to 120±5℃, add water-reducing agent, silica fume and precipitated barium sulfate and continue stirring for 1-2 hours; cool to room temperature, add inorganic pigment, stir for 30 minutes and then discharge to obtain the diamond abrasive wear-resistant flooring material.

[0010] In one or more embodiments of the present invention, the corundum is fused alumina sand with a Mohs hardness ≥9 and a particle size of 20 mesh, and the cement is 52.5 grade silicate cement or aluminate cement.

[0011] In one or more embodiments of the present invention, the water-reducing agent is a naphthalene-based water-reducing agent or a melamine water-reducing agent, wherein the mass ratio of the naphthalene-based water-reducing agent to the melamine water-reducing agent is (3:1)-(4:1).

[0012] In one or more embodiments of the present invention, the inorganic pigment is one or a combination of phthalocyanine green, titanium dioxide, iron oxide yellow, ultramarine, iron oxide, and iron oxide red.

[0013] Production equipment for corundum wear-resistant flooring materials includes screening equipment, which includes a pair of columns, an intermittent screening mechanism, and an air suction pump;

[0014] A housing is provided between the pair of columns, and the housing is provided with an inlet and an outlet.

[0015] The intermittent screening mechanism is installed inside the housing. The intermittent screening mechanism includes a servo motor, which is mounted on one of the columns. The output end of the servo motor is connected to a rotating shaft, which is rotatably connected to the housing and another column. A screening cylinder is connected to the side wall of the rotating shaft inside the housing. Multiple stirring mechanisms are installed on the side wall of the rotating shaft inside the screening cylinder.

[0016] The suction pump is installed on the top wall of the outer shell. The air outlet end of the suction pump is connected to an air outlet pipe. The end of the air outlet pipe located inside the outer shell is connected to an air jet cover. An electric heating wire is provided on the outside of the air outlet pipe, and a protective cover is provided on the outside of the electric heating wire.

[0017] In one or more embodiments of the present invention, the side wall of the screening cylinder is provided with a feeding port, which corresponds to the inlet. The corundum to be screened can be fed into the screening cylinder through the inlet and the feeding port, so as to screen the corundum and facilitate the subsequent production of corundum flooring materials.

[0018] The screening cylinder is equipped with a screen. Small-diameter diamond particles can be discharged through the screen, while large-diameter diamond particles will be retained to achieve the screening purpose. At the same time, it also facilitates the hot air sprayed by the jet hood to enter the screening cylinder through the screen to dry the diamond particles in the screening cylinder and reduce the moisture content of the diamond particles.

[0019] The outer wall of the screening cylinder is equipped with multiple heat-absorbing plates, which can absorb heat from the hot air to dry the diamond abrasive in contact with the inner wall of the screening cylinder, thus avoiding uneven drying of the diamond abrasive.

[0020] In one or more embodiments of the present invention, the stirring mechanism includes a stirring rod, which is fixedly connected to the side wall of the rotating shaft, and the stirring rod is used to install a reciprocating component;

[0021] The end of the stirring rod is connected to a limiting plate, which is used to limit the reciprocating parts so that the reciprocating parts will not slip out of the stirring rod;

[0022] A reciprocating component is slidably mounted on the stirring rod. Springs are provided on both sides of the reciprocating component, and the springs surround the stirring rod. When the rotating shaft rotates, the stirring rod can rotate synchronously. The reciprocating component is subjected to centrifugal force and slides on the stirring rod. Under the action of a pair of springs, it can slide back and forth. The stirring rod and the reciprocating springs are used to stir the diamond sand in the screening cylinder to achieve a better screening effect.

[0023] In one or more embodiments of the present invention, a ratchet is fixedly connected to the outer wall of the rotating shaft, the ratchet is disposed between the outer shell and the screening cylinder, a pin is installed on the outer wall of the screening cylinder, a pawl is installed on the pin, the pawl engages with the ratchet, and the unidirectional rotation of the screening cylinder can be achieved by the action of the ratchet and the pawl so that the screen is on the lower or upper side.

[0024] A telescopic rod is installed on the outer shell, and a slot is provided on the side wall of the screening cylinder. The free end of the telescopic rod passes through the outer shell and engages with the slot. When the screening cylinder does not need to rotate, the free end of the telescopic rod will be inserted into the slot to fix the screening cylinder and prevent the screening cylinder from rotating with the shaft.

[0025] In one or more embodiments of the present invention, a triggering mechanism is installed on the screening cylinder to trigger the air pump and the heating wire, so as to realize intelligent control of the air pump and the heating wire.

[0026] The triggering mechanism includes a sliding rod slidably connected to a screening cylinder. A first fixing plate and a mounting plate are respectively connected to both ends of the sliding rod. The mounting plate is located inside the screening cylinder, and a first chip is mounted on the mounting plate. A second chip is mounted on the inner wall of the screening cylinder, corresponding to the first chip. When the screen is at the lower side, the first chip and the second chip are separated, and the suction pump and heating wire do not operate. When the screen is at the upper side, the first chip and the second chip are in contact. At this time, the suction pump and the heating wire operate, and hot air is sprayed into the screening cylinder through the screen to dry the diamond abrasive inside the screening cylinder, thereby reducing the moisture content of the diamond abrasive and ensuring the production quality of subsequent diamond abrasive flooring materials.

[0027] A protective sleeve is provided between the mounting plate and the inner wall of the screening cylinder. The protective sleeve surrounds the first chip and the second chip and is used to protect the first chip and the second chip.

[0028] In one or more embodiments of the present invention, an air suction pipe is installed on the lower side of the outer casing, the air suction pipe corresponds to the discharge port, and a return pipe is connected between the air suction pipe and the air suction end of the air suction pump. A purification box is installed on the return pipe. When the air suction pump is running, the air suction pump can draw in the gas discharged from the discharge port through the air suction end, the return pipe and the air suction pipe, so as to reuse the residual heat in the gas and avoid heat loss. By setting up the purification box, particles in the reused gas can be filtered to prevent particles from affecting the air suction pump.

[0029] Compared with the prior art, the emery abrasion wear-resistant flooring material and its production equipment of the present invention can optimize the raw material ratio of the emery abrasion wear-resistant flooring material, and at the same time, can significantly reduce the moisture content during the production of the emery abrasion wear-resistant flooring material, avoid the caking of the emery abrasion wear-resistant flooring material, and thus improve the surface strength, wear resistance, flexural strength, compressive strength, stability and aesthetics of the emery abrasion wear-resistant flooring material during use, so as to meet the usage requirements.

[0070] Comparative Example 2

[0071] Compared with Example 1, the difference is that no sieving and drying process was performed, but otherwise the same as Example 1.

[0072] Test case

[0073] This example is used to test the appearance, color, flexural strength, compressive strength, abrasion resistance, and surface strength of a corundum abrasion-resistant flooring material.

[0074] Test standard: JC / T906-2002 "Cement-based wear-resistant materials for concrete floors", where the appearance standard requirements are: uniform and free of lumps, flexural strength (28d), MPa: ≥13.5, compressive strength (28d), MPa: ≥90, abrasion resistance ratio, %: ≥350, surface strength (indentation diameter), mm≤3.10.

[0075] Test method: When the concrete has initially set, grind the concrete until it becomes slurry, then sprinkle the abrasive-resistant flooring material onto the surface at a rate of 4 kg / m². 2 Then grind it smooth, and after the surface has completely hardened, conduct the test according to the testing standards. The test results are as follows: Figure 1 As shown.

[0076] according to Figure 1As can be seen, in Examples 1 to 7 of this application, the appearance is uniform, without any clumping, and the flexural strength, compressive strength, abrasion resistance, and surface strength all meet the standards. Comparative Example 1 shows unevenness, and its flexural strength, abrasion resistance, and surface strength are relatively poor. Comparative Example 2 shows clumping, and its compressive strength, abrasion resistance, and surface strength are also poor.

[0077] like Figures 2 to 13 As shown, the production equipment for corundum wear-resistant flooring materials includes screening equipment, which includes a pair of columns 1, an intermittent screening mechanism 2, and an air suction pump 3.

[0078] Among them, a housing 101 is provided between a pair of columns 1. The housing 101 is provided with an inlet 102 and an outlet 103. Material can be fed into the screening cylinder 203 inside the housing 101 through the inlet 102. The screened diamond abrasive is discharged from the housing 101 through the outlet 103.

[0079] like Figures 2 to 13 As shown, the intermittent screening mechanism 2 is installed inside the housing 101. The intermittent screening mechanism 2 is used to screen corundum for better subsequent production of corundum wear-resistant flooring materials.

[0080] The intermittent screening mechanism 2 includes a servo motor 201, which is mounted on one of the columns 1. The output end of the servo motor 201 is connected to a rotating shaft 202, which is rotatably connected to the housing 101 and the other column 1. When the servo motor 201 is running, it can drive the rotating shaft 202 to rotate.

[0081] In addition, a sieve cylinder 203 is connected to the side wall of the rotating shaft 202 inside the housing 101. The sieve cylinder 203 is used to temporarily store the corundum to achieve sieving of the corundum.

[0082] Preferably, the servo motor 201 can rotate in both directions and can also execute rotation and pause commands to complete the screening and drying of the diamond abrasive in the screening cylinder 203.

[0083] like Figures 2 to 13 As shown, the screening cylinder 203 has a feeding port 2031 on its side wall, which corresponds to the inlet 102. The corundum to be screened can be fed into the screening cylinder 203 through the inlet 102 and the feeding port 2031, so as to screen the corundum and facilitate the subsequent production of corundum flooring materials.

[0084] The screening cylinder 203 is equipped with a screen 2032. Small-diameter diamond particles inside the screening cylinder 203 can be discharged through the screen 2032, while large-diameter diamond particles are retained, thus achieving the screening purpose. Simultaneously, when the screen 2032 is in the upper position, i.e. Figure 10The state shown also facilitates the hot air ejected by the jet hood 302 to enter the screening cylinder 203 through the screen 2032, so as to dry the diamond abrasive in the screening cylinder 203, thereby reducing the moisture content of the diamond abrasive and avoiding unevenness or clumping of the subsequent diamond abrasive wear-resistant flooring material.

[0085] This application provides a screen 2032 on the screening cylinder 203, which allows for intermittent screening and drying. For example, the screen 2032 can be rotated to the lower side for screening for 5 minutes, and then rotated to the upper side for drying for 5 minutes. This avoids large particles of diamond grit clogging the mesh of the screen 2032 during the screening process, thus preventing a decrease in screening efficiency. At the same time, it also allows for the drying of the diamond grit to reduce its moisture content.

[0086] In addition, multiple heat-absorbing plates 2034 are installed on the outer wall of the screening cylinder 203. The heat-absorbing plates 2034 can absorb heat from the hot air, that is... Figure 10 The diagram shown illustrates the gas flow pattern, which is used to dry the diamond abrasive in contact with the inner wall of the screening cylinder 203, thus preventing uneven drying of the diamond abrasive.

[0087] like Figures 2 to 13 As shown, the rotating shaft 202 is located on the side wall inside the screening cylinder 203 and is equipped with multiple stirring mechanisms 204. The stirring mechanisms 204 can rotate with the rotating shaft 202, thereby stirring the diamond sand in the screening cylinder 203, so that the diamond sand can be dispersed and the diamond sand can be screened better.

[0088] The stirring mechanism 204 includes a stirring rod 2041, which is fixedly connected to the side wall of the rotating shaft 202. The stirring rod 2041 is used to mount the reciprocating component 2043. A limiting plate 2042 is connected to the end of the stirring rod 2041. The limiting plate 2042 is used to limit the reciprocating component 2043 so that the reciprocating component 2043 will not slip out of the stirring rod 2041.

[0089] In addition, a reciprocating element 2043 is slidably mounted on the stirring rod 2041, and springs 2044 are provided on both sides of the reciprocating element 2043, with the springs 2044 surrounding the stirring rod 2041. When the rotating shaft 202 rotates, the stirring rod 2041 can rotate synchronously. The reciprocating element 2043 is subjected to the centrifugal force of rotation and slides on the stirring rod 2041, and can reciprocate under the action of a pair of springs 2044. The stirring rod 2041 and the reciprocating springs 2044 are used to stir the diamond powder in the screening cylinder 203, so that the diamond powder can be dispersed to achieve a better screening effect.

[0090] Preferably, the stirring rod 2041 and the reciprocating part 2043 are both made of heat-conducting materials. The stirring rod 2041 and the reciprocating part 2043 can also absorb the hot air ejected by the jet hood 302, which facilitates better drying of the diamond abrasive.

[0091] like Figures 2 to 13 As shown, a ratchet 205 is fixedly connected to the outer wall of the rotating shaft 202. The ratchet 205 is located between the outer casing 101 and the screening cylinder 203. A pin 206 is installed on the outer wall of the screening cylinder 203, and a pawl 207 is installed on the pin 206. The pawl 207 engages with the ratchet 205. Through the action of the ratchet 205 and the pawl 207, the screening cylinder 203 can be rotated in one direction, so that the screen 2032 is positioned on the lower or upper side.

[0092] If it is necessary to screen the corundum, rotate the screen 2032 to the lower side, insert the free end of the telescopic rod 209 into the slot 2033, control the rotating shaft 202 to rotate counterclockwise, the rotating shaft 202 drives the stirring mechanism 204 to rotate, while the screening cylinder 203 will not rotate due to the fixation of the telescopic rod 209. At this time, the stirring mechanism 204 can disperse the corundum, which is convenient for screening.

[0093] If it is necessary to rotate the screen 2032 to the upper side, control the telescopic rod 209 to retract so that the free end of the telescopic rod 209 does not engage with the slot 2033, control the rotating shaft 202 to rotate clockwise, and through the engaging action of the ratchet 205 and the pin 206, drive the screening cylinder 203 to rotate so that the screen 2032 can be rotated to the upper side.

[0094] like Figures 2 to 13 As shown, a triggering mechanism 208 is installed on the screening cylinder 203 to trigger the air pump 3 and the heating wire 303, so as to realize the intelligent control of the air pump 3 and the heating wire 303.

[0095] The triggering mechanism 208 includes a sliding rod 2081, which is slidably connected to the screening cylinder 203. The two ends of the sliding rod 2081 are respectively connected to a first fixing plate 2082 and a mounting plate 2083. The mounting plate 2083 is located inside the screening cylinder 203. A first chip 2084 is installed on the mounting plate 2083. A second chip 2085 is installed on the inner wall of the screening cylinder 203. The second chip 2085 corresponds to the first chip 2084.

[0096] When the screen 2032 is at the lower position, the first chip 2084 and the second chip 2085 separate under gravity. At this time, the suction pump 3 and the heating wire 303 do not operate. When the screen 2032 is at the upper position, the first chip 2084 and the second chip 2085 come into contact with each other under gravity. At this time, the suction pump 3 and the heating wire 303 operate. The suction pump 3 draws in external gas and heats it instantly through the heating wire 303. The hot gas is sprayed into the screening cylinder 203 through the exhaust pipe 301, the air jet hood 302, and the screen 2032. The hot gas is used to dry the diamond abrasive inside the screening cylinder 203, thereby reducing the moisture content of the diamond abrasive and ensuring the production quality of subsequent diamond abrasive flooring materials.

[0097] At the same time, by spraying hot air onto the screen 2032 through the jet hood 302, any diamond powder that may be adhering to the screen 2032 can be blown off, preventing the screen 2032 mesh from being blocked by diamond powder, thus ensuring the subsequent screening effect.

[0098] In addition, a protective sleeve 2086 is provided between the mounting plate 2083 and the inner wall of the screening cylinder 203. The protective sleeve 2086 surrounds the first chip 2084 and the second chip 2085 and is used to protect the first chip 2084 and the second chip 2085.

[0099] Preferably, the protective cover 2086 is made of heat-resistant rubber.

[0100] Specifically, a telescopic rod 209 is installed on the outer casing 101, and a slot 2033 is provided on the side wall of the screening cylinder 203. The free end of the telescopic rod 209 passes through the outer casing 101 and engages with the slot 2033. When the telescopic rod 209 is inserted into the slot 2033, the screening cylinder 203 cannot rotate with the rotating shaft 202. When the telescopic rod 209 is disengaged from the slot 2033, the screening cylinder 203 can rotate with the rotating shaft 202 to adjust the position of the screen 2032.

[0101] like Figures 2 to 13 As shown, the suction pump 3 is installed on the top outer wall of the housing 101. The air outlet end of the suction pump 3 is connected to the air outlet pipe 301, which is made of a heat-conducting material. One end of the air outlet pipe 301 located inside the housing 101 is connected to the jet shroud 302. When the suction pump 3 is running, it draws in outside air, and the air is delivered into the jet shroud 302 through the air outlet pipe 301.

[0102] Among them, an electric heating wire 303 is provided on the outside of the air outlet pipe 301. The electric heating wire 303 is used to heat the gas flowing in the air outlet pipe 301 in real time to increase the gas temperature, so as to use the hot air to dry the diamond in the screening cylinder 203 and reduce the moisture content of the diamond.

[0103] In addition, a protective cover 304 is provided on the outside of the heating wire 303 to protect the heating wire 303.

[0104] like Figures 2 to 13 As shown, a suction pipe 4 is installed on the lower side of the outer casing 101. The suction pipe 4 corresponds to the discharge port 103, and a return pipe 401 connects the suction pipe 4 to the suction end of the suction pump 3. When the suction pump 3 is running, it can draw in the gas discharged from the discharge port 103 through the suction end, the return pipe 401, and the suction pipe 4, so as to reuse the residual heat in the gas and avoid heat loss.

[0105] A purification box 402 is installed on the return pipe 401. The purification box 402 can filter particles in the reused gas to prevent particles from affecting the suction pump 3.

[0106] In practical use, the diamond powder to be screened is placed inside the screening cylinder 203 through the inlet 102 and the feed port 2031. The servo motor 201 is controlled to rotate the shaft 202 counterclockwise. The screening cylinder 203 is not subjected to force; only the stirring mechanism 204 rotates synchronously with the shaft 202. The rotating stirring mechanism 204 disperses the diamond powder inside the screening cylinder 203, allowing it to be better screened through the screen 2032. The screened diamond powder is discharged from the outer casing 101 through the outlet 103.

[0107] After sieving carborundum on screen 2032 for 5 minutes, servo motor 201 stops, and telescopic rod 209 retracts, causing its free end to disengage from engagement slot 2033. Servo motor 201 restarts, rotating shaft 202 clockwise. Through the engagement of ratchet 205 and pawl 207, screening cylinder 203 also rotates clockwise. When screening cylinder 203 rotates 90° clockwise, i.e., when screen 2032 reaches the upper position, as... Figure 10 At the position shown. Servo motor 201 stops running, telescopic rod 209 extends, and the free end of telescopic rod 209 re-engages with slot 2033. Then, control servo motor 201 to run again, causing shaft 202 to rotate counterclockwise again, and stirring mechanism 204 can stir the diamond sand in screening cylinder 203.

[0108] Simultaneously, under the influence of gravity, the first chip 2084 and the second chip 2085 come into contact with each other. At this time, the suction pump 3 and the heating wire 303 operate. The suction pump 3 draws in external gas and heats it instantly through the heating wire 303. The hot gas is injected into the screening cylinder 203 through the exhaust pipe 301, the air jet hood 302, and the screen 2032. The hot gas is used to dry the diamond abrasive inside the screening cylinder 203, reducing its moisture content and ensuring the production quality of subsequent diamond abrasive flooring materials. At the same time, the hot gas injected into the screen 2032 through the air jet hood 302 can also blow off any diamond abrasive that may be adhering to the screen 2032, preventing the screen mesh from being blocked by diamond abrasive and ensuring the subsequent screening effect.

[0109] The hot air inside the screening cylinder 203 passes through the heat-absorbing plate 2034, which absorbs heat from the hot air. Figure 10 The diagram shows the gas flow and the heat is transferred to the screening cylinder 203 to dry the diamond abrasive in contact with the inner wall of the screening cylinder 203, thus avoiding uneven drying of the diamond abrasive.

[0110] The hot air inside the outer casing 101 is also discharged through the discharge port 103, which is used to blow out the diamond powder remaining near the discharge port 103. At the same time, due to the operation of the suction pump 3, the suction pump 3 can also draw in the gas discharged from the discharge port 103 through the suction end, return pipe 401 and suction pipe 4, so as to reuse the residual heat in the gas and avoid heat loss.

[0111] After the diamond abrasive in the screening cylinder 203 has been dried for 5 minutes, the screen 2032 is rotated to the lower side, and this process is repeated. This application can extend the screening or drying time by adjusting the screen 2032 up and down, thus ensuring the screening and drying effect of the diamond abrasive.
