Description

Technical Field

[0001] This invention relates to the field of composite material decorative panels, specifically to a manufacturing process for a moisture-proof inorganic composite material decorative panel. Background Technology

[0002] Moisture-proof inorganic composite decorative panels are mainly composed of inorganic substrates, moisture-proof additives, and other auxiliary materials. Inorganic substrates, such as silicates and diatomaceous earth, possess excellent water resistance and weather resistance. Moisture-proof additives, such as activated carbon and molecular sieves, effectively absorb and release moisture, improving the moisture-proof performance of the decorative panels. Furthermore, these panels are environmentally friendly, non-toxic, and non-radioactive. Manufacturing these panels requires preparing raw materials such as inorganic substrates, moisture-proof additives, and auxiliaries according to the production formula. The inorganic substrates and moisture-proof additives are then added to a mixing device in proportion and stirred evenly. The stirred material is then pressed into decorative panels of the required shape and size using a sheet press or molding machine. Finally, it undergoes hot pressing and surface polishing or spraying. This moisture-proof inorganic composite decorative panel and the process used to produce it can be referred to as a moisture-proof inorganic composite decorative panel and its manufacturing process.

[0003] However, the moisture-proof inorganic composite decorative panels currently on the market mainly fall into two categories: metal panels with coated surfaces and inorganic panels with coated surfaces. Both types of panels have relatively low strength and are prone to surface cracking upon impact or compression, thus limiting their application. Patent number CN214739241U, titled "A High-Strength Carbon Fiber Composite Panel," addresses this issue by adding rubber material inside the composite panel, effectively improving its overall compressive strength and preventing cracking under pressure. Furthermore, the addition of a mesh-like carbon fiber material inside the reinforcing panel further strengthens the overall structure, broadening its application range and extending its service life. This solution addresses the problem of low strength and surface cracking upon impact or compression.

[0004] However, when using a hot press to produce this type of moisture-proof inorganic composite decorative board, the heat emitted by the hot press plates will directly dissipate into the outside air, resulting in energy waste. Furthermore, existing hot presses contain multiple springs connected to the hot press plates. During the hot pressing process, these springs are compressed. With increased use, the springs age due to the increased compression, and aged springs are prone to deformation or breakage. If a breakage occurs, the hot press plates will not maintain their correct position and working state, causing equipment malfunction. Moreover, when the springs lose their original elasticity, they will be unable to push the hot press plates back to their original position, leading to changes in the gap between the hot press plates. Severe spring aging can even cause the gap between the hot press plates to be smaller than the thickness of the board. Therefore, these methods do not meet current requirements. To address this, we propose a moisture-proof inorganic composite decorative board and its manufacturing process. Summary of the Invention

[0005] The purpose of this invention is to provide a moisture-proof inorganic composite decorative panel and its manufacturing process, to solve the problems mentioned in the background art, such as the heat emitted by the hot press plates when producing this type of moisture-proof inorganic composite decorative panel using a hot press, which directly dissipates into the outside air, resulting in energy waste; and the fact that existing hot press machines have multiple hot press plates connected to multiple springs, which are compressed during the hot pressing process. With increased use, the springs age due to the increased compression, and aged springs are prone to deformation or breakage. Once broken, the hot press plates cannot maintain the correct position and working state, causing equipment failure. Furthermore, when the springs lose their original elasticity, they cannot push the hot press plates back to their original position, resulting in changes in the gap between the hot press plates. If the springs are severely aged, the gap between the hot press plates may even be smaller than the thickness of the panel.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figures 1 to 6 The present invention provides an embodiment of a moisture-proof inorganic composite decorative panel, comprising a composite panel 1, wherein the composite panel 1 comprises a substrate layer 101, two moisture-proof layers 102, two decorative surface layers 103 and two protective coatings 104, wherein the two moisture-proof layers 102 are respectively located on the upper and lower end faces of the substrate layer 101, the decorative surface layer 103 is fixed to the outer surface of the moisture-proof layer 102, and the protective coatings 104 are applied to the outer surface of the decorative surface layer 103;

[0035] Step A: Raw material preparation. According to the production formula, prepare inorganic base material, moisture-proof additive, and auxiliary raw materials, and add the inorganic base material and moisture-proof additive to the mixing equipment in proportion and mix evenly.

[0036] Step B: This step involves using a tablet press or molding machine to shape the mixed material into decorative panels of the desired shape and size.

[0037] Step C: The pressed decorative panel is then placed on a hot press for hot circulation. The hot press for hot circulation can be used to heat-press the panel, thereby fully curing the material in the decorative panel to achieve the required physical properties.

[0038] Step D: The surface of the cured decorative panel is sanded or sprayed to meet the decorative requirements;

[0039] The hot press device for hot circulation includes an inverted concave plate 26. A hot circulation mechanism is provided on the lower side inside the inverted concave plate 26. The hot circulation mechanism includes a large sealing box 5, a hot gas sealing groove 6, a hot gas collection groove 7, a piston groove 9, a square plate 3, and an automatic suction and exhaust mechanism. Hot gas is provided inside the hot gas collection groove 7 and the piston groove 9. When the square plate 3 is inserted into the hot gas sealing groove 6, the automatic suction and exhaust mechanism can automatically input hot gas into the hot gas sealing groove 6. When the square plate 3 moves upward, the automatic suction and exhaust mechanism can automatically extract the hot gas input into the hot gas sealing groove 6 and transfer it to the hot gas collection groove 7 and the piston groove 9. The hot circulation mechanism also includes two single-cylinder cylinders B25. The two single-cylinder cylinders B25 are fixed on both sides inside the inverted concave plate 26, and the piston push rods on the single-cylinder cylinders B25 are connected to the square plate 3. When the equipment is needed, the motor is connected, and the square plate 3 is pushed downward by the single-cylinder cylinders B25.

[0040] A downward pushing plate 24 is fixed on both sides of the lower end face of the square plate 3. An inverted L-shaped opening 8 is provided on both sides of the interior of the large sealing box 5. The hot air collection groove 7 communicates with the interior of the hot air sealing groove 6 through the inverted L-shaped opening 8. A cuboid groove 27 is provided on both sides of the inner wall of the hot air sealing groove 6. The cuboid groove 27 vertically penetrates the inverted L-shaped opening 8, and the positions of the two cuboid grooves 27 correspond to the positions of the two downward pushing plates 24 respectively.

[0041] The interior of the cuboid groove 27 is provided with a sealing plate 18. One side of the outer surface of the sealing plate 18 is provided with a square through hole 19 penetrating the sealing plate 18. A metal guide rod 20 is provided at the front and rear of the bottom end of the sealing plate 18. An anti-disengagement sleeve 21 is fitted on the outer surface of the metal guide rod 20. The anti-disengagement sleeve 21 facing the sealing plate 18 is fixed to the sealing plate 18, and a spring 22 is connected to the lower end face of the anti-disengagement sleeve 21. As the square plate 3 descends, the square plate 3 will enter the interior of the hot air sealing groove 6. When the square plate 3 continues to descend inside the hot air sealing groove 6, the downward push plate 24 fixed to its lower end face will contact the sealing plate 18 located inside the cuboid groove 27 and push the sealing plate 18 downward. As the sealing plate 18 moves, the square through hole 19 located in the sealing plate 18 will move to the position of the inverted L-shaped opening 8. When the square through hole 19 moves to this position, the inverted L-shaped opening 8 sealed by the sealing plate 18 will be opened.

[0042] Furthermore, when the sealing plate 18 moves downward, the anti-disengagement sleeve 21 fixed to it will also move downward. When the anti-disengagement sleeve 21 moves downward, it will compress the spring 22.

[0043] A push rod A23 is provided on one side of the pressing push plate 24, with its upper end face fixed to the square plate 3. Below the push rod A23, a push rod B17 is located inside the large sealed box 5. A rectangular transmission head 16 is provided on one side of the bottom end of the push rod B17. The surfaces of the push rod B17 facing the rectangular transmission head 16 and the surfaces of the rectangular transmission head 16 facing the push rod B17 are both inclined surfaces. A connecting rod 15 is connected to the opposite surfaces of the two rectangular transmission heads 16. The opposite surfaces of the two connecting rods 15 are connected to... A rectangular pusher head 14 is connected to the piston head 9. A sloping pusher plate 13 is provided between the two rectangular pusher heads 14. A piston head 10 located inside the piston groove 9 is fixedly connected to the upper end face of the sloping pusher plate 13. A metal rod 11 is vertically movable through the front and rear ends of the piston head 10. A return spring 12 is sleeved on the outer surface of the metal rod 11, and its lower end face is connected to the upper end face of the piston head 10. When the inverted L-shaped opening 8 is opened and the square plate 3 continues to descend, the return spring 12 is fixed to the lower end face of the square plate 3. The push rod A23 will then contact the push rod B17 and push the push rod B17 downward. As the push rod B17 descends, the rectangular transmission head 16 located on one side of the bottom end of the push rod B17 will contact it. When the two contact each other, the rectangular transmission head 16 can be pushed inward through the inclined surface on the outer surface of the two. As the rectangular transmission head 16 moves, the rectangular push head 14 connected to it through the connecting rod 15 will also move inward. When the rectangular push heads 14 on both sides move inward synchronously, the inclined push plate 13 located between the two rectangular push heads 14 will be pushed upward. As the inclined push plate 13 rises, the piston head 10 fixed to it will also rise. When the piston head 10 rises inside the return spring 12, the hot air inside the piston groove 9 and the hot air receiving groove 7 will be input into the hot air sealing groove 6 through the inverted L-shaped port 8. The hot air entering the hot air sealing groove 6 will act on the composite material plate 1 placed on the upper surface of the hot press plate.

[0044] After the hot pressing of the composite material plate 1 is completed, the square plate 3 is moved upward. As the square plate 3 rises, the piston head 10 is pushed downward by the reaction force generated by the return spring 12 squeezed by the piston head 10 moving upward. When the piston head 10 moves downward inside the return spring 12, it will draw out the hot air inside the hot air sealing groove 6. During the process of drawing out the hot air, the piston head 10 will gradually push the sealing plate 18 upward by the reaction force of the squeezed spring 22. When the lower end face of the piston head 10 is in contact with the inner wall of the return spring 12, the drawing is completed. After the hot air is drawn out, the rising sealing plate 18 will also seal the inverted L-shaped opening 8 again. Through the above technical solution, the hot air emitted during the hot pressing of the plate can be retained and recycled, thereby reducing the energy waste caused by using this equipment.

[0045] A springless automatic reset pressing and heating mechanism 2 is fixedly installed on the lower end face of the square plate 3. The springless automatic reset pressing and heating mechanism 2 includes a hot press plate A202. A single-cylinder cylinder A4 is fixedly installed at the middle position of the upper end face of the square plate 3, and the piston rod of the single-cylinder cylinder A4 is connected to the hot press plate A202. Before using this device, a composite material plate 1 is placed on the upper end face of each hot press plate C204 and hot press plate B203. When the square plate 3 has completely entered the interior of the hot gas sealing groove 6 and the hot gas has been completely input into the interior of the hot gas sealing groove 6, the single-cylinder cylinder A4 is activated, and the hot press plate A202 can be pushed downward by the single-cylinder cylinder A4.

[0046] Below the hot press plate A202 are multiple hot press plates B203, and below the multiple hot press plates B203 is a hot press plate C204. A metal rod is fixed to each of the four corners of the upper surface of the hot press plate C204, and the upper surface of the metal rod is fixed to the lower surface of the square plate 3 by movably passing through the hot press plates B203 and A202. An L-shaped plate 205 is fixed to both sides of the lower surface of the hot press plates A202 and B203. An L-shaped groove 206 is provided on both sides inside the hot press plates A202 and C204, and the bottom end of the L-shaped plate 205 is located inside the L-shaped groove 206. Since the hot press plates A202, B203, and C204 are all connected by the L-shaped plates 205 and L-shaped grooves 206, when the hot press plate A202 moves downwards... At that time, under the action of gravity, the bottommost hot press plate B203 will come into contact with the composite material plate 1 placed on the upper surface of the hot press plate C204. When the bottommost hot press plate B203 comes into contact with the composite material plate 1, and the hot press plate A202 is still being pushed downward by the single-cylinder cylinder A4, the lower surface of the second hot press plate B203 from the bottom will come into contact with the composite material plate 1 placed on the bottommost hot press plate B203. This continues until the lower surfaces of all the hot press plates B203 and the lower surfaces of the hot press plate A202 are connected to the composite material plate 1. Then, the pressure generated by the single-cylinder cylinder A4 is used to press the composite material plate 1, and the heat emitted by the hot press plates A202, B203 and C204 is used to heat the composite material plate 1.

[0047] After the hot pressing of composite material plate 1 is completed, hot press plate A202 is pulled upward by single-cylinder cylinder A4. As hot press plate A202 rises, L-shaped plate 205 fixed to the lower end face of hot press plate A202 also rises inside L-shaped groove 206. When L-shaped plate 205 fixed to the lower end face of hot press plate A202 can no longer rise inside L-shaped groove 206, the gap between hot press plate A202 and hot press plate B203 can no longer increase. As hot press plate A202 rises at this time, hot press plate B203 at the top will move upward. As hot press plate B203 rises, L-shaped plate 205 fixed to the lower end face of hot press plate B203 will also rise inside the corresponding L-shaped groove 206 until hot press plate A202 as a whole can no longer be pulled upward. At this time, the gap between hot press plate A202, hot press plate B203 and hot press plate C204 is the same.

[0048] A square groove is provided in the middle of the front face of hot press plate A202, hot press plate B203 and hot press plate C204. A semi-cylindrical metal rod 201 is provided inside the row of square grooves near the front face of square plate 3 and the row of square grooves near the rear face of square plate 3. A stepper motor 209 is fixedly installed on one side inside the semi-cylindrical metal rod 201. The output shaft of the stepper motor 209 is connected to the motor shaft 210 through a coupling. A threaded shaft 211 is provided above and below the motor shaft 210. The two threaded shafts 211 and one motor shaft 210 are connected in series through a synchronous chain 213.

[0049] A threaded rod 212 is fixedly connected to the face of the threaded shaft 211 facing the hot press plate B203. A rectangular plate 214 is movably provided on the other side inside the semi-cylindrical metal rod 201. The threaded rod 212 passes through the rectangular plate 214 laterally. The threaded rod 212 and the rectangular plate 214 are connected by a threaded structure. The top and bottom ends of the rectangular plate 214 are both passed through laterally by a guide rod.

[0050] Each of the square grooves on the outer surfaces of hot press plates A202, B203, and C204 has a fixing port 207 on one side. A rectangular plate 214 has multiple fixing heads 208, the same number as the fixing ports 207 and corresponding in position, fixed on the side facing the fixing port 207. The top ends of the fixing heads 208 are inserted into the fixing ports 207. When the hot press plate A202 can no longer move upwards, the stepper motor 209 is activated. The stepper motor 209 drives the connected motor shaft 210 and synchronizes with it. The chain 213 drives the threaded shaft 211 to rotate. When the threaded shaft 211 rotates, the threaded rod 212 fixed to it also rotates. When the threaded rod 212 rotates, it is connected to the rectangular plate 214 by threads. However, because both its top and bottom ends are pierced by a guide rod, the rectangular plate 214, which cannot rotate on its own, will move back and forth under the transmission of the threaded structure. When the hot press plate A202 is pulled to its highest point, the rectangular plate 214 moves inward. As the rectangular plate 214 moves, the fixing head 208 fixed to the outer surface of the rectangular plate 214 will also move. Subsequently, it is inserted into the fixing port 207 on the inner wall of the square groove located in the middle of the front and rear end faces of hot press plates A202, B203, and C204, thereby fixing the position of hot press plates A202, B203, and C204. After the positions of hot press plates A202, B203, and C204 are fixed, the single-cylinder cylinder A4 can be closed. When it is necessary to push hot press plate A202 downward through the single-cylinder cylinder A4, the fixing head 208 needs to be moved outward by the stepper motor 209 to release the control over hot press plates A202 and C204. Only with the fixing of plate B203 and hot press plate C204 can hot press plate A202 continue to be pushed downwards. Through the above technical solution, hot press plates A202, B203 and C204 can be automatically separated without the use of springs, and the gap between hot press plates A202, B203 and C204 can always be kept consistent and the size of the gap will not change. This can prevent the composite material plate 1 from becoming unplaceable as the usage time increases, and can ensure that the hot press plates maintain the correct position and working condition.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
