Description

Technical Field

[0001] The present invention relates to the technical field of aluminum veneers, and specifically to an aluminum veneer with easily cleanable surface attachments and its production process. Background Art

[0002] An aluminum veneer refers to a building decoration material formed by processes such as chromating and then adopting fluorocarbon coating technology.

[0003] The patent application No. 202120890194.2 discloses an easily cleanable and antibacterial aluminum veneer. When rainwater falls into the water storage box and the precipitation submerges the airbag, the airbag will drive the floating plate to rotate counterclockwise under the action of buoyancy. At this time, the floating plate will pull the flap obliquely upward through the lifting rope, and the flap will rotate counterclockwise along the support rod. The flap separates from the baffle to form a water outlet, and the accumulated rainwater can wash the aluminum plate through the water outlet, thereby realizing that the antibacterial aluminum veneer can utilize natural resources to effectively clean the dirt on the antibacterial aluminum plate and ensure the clean surface of the aluminum plate.

[0004] In the above patent, although the surface of the aluminum plate can be cleaned with the help of equipment, there will be narrow installation gaps between the segmented aluminum plate structures. When dust and sewage generated during cleaning enter the gaps, they cannot be cleaned, and long-term accumulation will also corrode the paint surface of the aluminum plate. Therefore, it does not meet the existing requirements, and for this reason, an aluminum veneer with easily cleanable surface attachments and its production process are proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an aluminum veneer with easily cleanable surface attachments and its production process. The gap connecting films between the aluminum decoration plate bodies can be attracted and combined together by a magnetic attraction structure, so that a diaphragm can be formed between the gaps. The diaphragm can intercept dust and sewage generated during cleaning and daily processes outside the diaphragm, and a cleaning coating will also be applied to the surface of the diaphragm, thereby avoiding the accumulation of dust and debris, and solving the problems in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An aluminum veneer with easily cleanable surface attachments, including an aluminum decoration plate body. Installation ear plates are provided at the bottoms of the four sides of the aluminum decoration plate body. The installation ear plates are connected to the aluminum decoration plate body by screws. Side slots are provided on the surfaces of the four sides of the aluminum decoration plate body. Inner support reinforcing ribs are provided inside the aluminum decoration plate body. The inner support reinforcing ribs are connected to the installation ear plates by screws. A gap connecting film is provided between the inner support reinforcing ribs and the aluminum decoration plate body. A fluorocarbon coating is provided on the outer surface of the aluminum decoration plate body, and an aerogel coating is provided on the inner surface of the aluminum decoration plate body.

[0007] Preferably, the gap connecting film includes a limit rubber plug, a sealing rubber strip, an extended edge film and a magnet inlay. The limit rubber plug, the sealing rubber strip and the extended edge film are set as an integral structure. Among them, the sealing rubber strip is arranged between the limit rubber plug and the extended edge film.

[0008] Preferably, the magnet inlay is connected to the extended edge film through an adhesive. The limit rubber plug is connected to the main body of the aluminum decorative plate through side slots. The sealing rubber strip is attached to the surface around the main body of the aluminum decorative plate.

[0009] Preferably, the gap connecting films are suction-connected through the magnet inlays.

[0010] A production process of an aluminum single plate with an easily cleanable surface attachment includes the following steps:

[0011] Step 1: Punch the four sides of the cast aluminum single plate, leave two arc-shaped side slots on each side, then polish its outer surface, degrease and clean the outer surface after polishing, and finally perform chromating treatment on the outer surface;

[0012] Step 2: After the chromating treatment is completed, carry out the spraying process of the primer. Preheat the fluorocarbon coating, control the temperature at 120 - 150 °C. After the temperature is qualified, atomize the fluorocarbon coating into extremely fine particles with a high-speed air flow and spray it onto the outer surface of the aluminum single plate at a high speed to form a primer coating. The thickness of the primer coating is set at 5 - 7 μm;

[0013] Step 3: After the primer is sprayed, perform high-temperature baking, control the temperature at 225 - 235 °C. After the primer is dried, carry out the spraying process of the topcoat. Pigments can be added according to the color requirements of the outer surface during the spraying of the topcoat. The thickness of the topcoat layer is set at 23 - 30 μm;

[0014] Step 4: After the topcoat is dried, carry out the spraying process of the varnish. The thickness of the varnish is 5 - 10 μm. After the three-layer paint film is cured, the entire single aluminum plate needs to be placed in a curing furnace for secondary curing treatment. The secondary curing temperature is controlled at 180 - 250 °C, and the curing time is 15 - 25 min;

[0015] Step 5: After the outer surface coating process is completed, perform heat insulation treatment on the inner surface of the single aluminum plate. First, spray a temperature-bearing coating material on the inner surface to prevent the aluminum plate surface from being exposed to the air. The thickness of the pre-coating is 5 - 8 μm;

[0016] Step 6: After the pre-coating is dried, carry out the first coating of the aerogel heat insulation coating, control the thickness at 3 - 6 mm. After the first layer is dried, the thickness can be appropriately increased to 6 mm starting from the second layer, with a total of three layers;

[0017] Step 7: Place the entire single aluminum plate in an injection mold, inject natural latex into the interior of the mold, the latex passes through the side slots and enters the inner side of the single aluminum plate, and the latex cures and forms in the interior of the mold to form a gap-connected film;

[0018] Step 8: Fit a set of annular magnetic strips into the grooves around the extended edge film, then use UV curable glue to bond and fix the installation gap between the magnetic strips and the edge film. Finally, place the inner support reinforcing ribs on the inner side of the single aluminum plate and connect and fix them.

[0019] Preferably, in Step 1, after punching, the burrs on the edges of the holes are polished.

[0020] Preferably, in Step 4, after spraying the topcoat, wait until the temperature drops to 70 - 80 °C and then perform the operation of spraying the clear coat.

[0021] Preferably, in Step 6, after the interior surface coating is dried and cured, place the interior surface of the single aluminum plate above a high-temperature detection device for heating, and collect and analyze the gas components in the exterior surface area to determine whether there are harmful gases produced.

[0022] Preferably, in Step 6, the next coat must be applied after the previous coat is completely dry.

[0023] Preferably, after the aerogel thermal insulation coating is cured, there are no visible oils, greases, and dirt on the surface, and there are no poorly adhered coatings, impurities, and foreign objects affecting adhesion.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In the present invention, a set of gap-connected films are installed around the aluminum decorative plate body. During the assembly process of the aluminum single plates, the gap-connected films between the aluminum decorative plate bodies can be attracted together by the magnetic attraction structure, so that a diaphragm can be formed between the gaps. The diaphragm can intercept the dust and sewage generated during cleaning and daily processes on the outer side of the diaphragm, and a cleaning coating is also applied to the surface of the diaphragm to avoid the accumulation of dust and debris. And the entire diaphragm is located inside the aluminum decorative plate body and will not be affected by air flow and wind, which can prevent the diaphragm from disconnecting;

[0026] 2. In the present invention, the outer surface of the aluminum veneer body is processed by using the traditional fluorocarbon spraying technology. Fluorocarbon spraying has excellent anti-fading property, anti-frosting property, corrosion resistance against air pollution, strong anti-ultraviolet ability, strong anti-cracking property and can withstand harsh weather conditions. Aerogel coating is newly added to the inner surface of the aluminum plate. The coating of aerogel can effectively isolate the heat transfer to the inside of the aluminum plate when a building catches fire. Since the thermal decomposition reaction of fluorocarbon will produce harmful substances such as toxic phosgene and fluorocyclohexanol, aerogel can reduce the probability of thermal decomposition of the fluorocarbon coating under the influence of continuous high temperature.

[0027] 3. In the present invention, the limit rubber plug, the sealing rubber strip and the extended edge film are integrally cast by using the injection molding process. The limit rubber plug is located inside the side grooves around the aluminum single plate. The limit rubber plug is between the aluminum veneer body and the inner support reinforcing rib. While achieving fixed support, it can also play a buffering role at the connection gap between the aluminum single plate and the inner support reinforcing rib. The sealing rubber strip is attached to the peripheral surface of the aluminum single plate, covering the entire side groove, preventing dust and moisture from entering the inside of the aluminum single plate from the gap. The extended edge film is used to connect the magnet inlay, so that the extended edge films between the aluminum plates can achieve suction connection. The extended edge film itself has strong stretchability and can also adapt to the physical properties of the metal structure after suction fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-4 , an embodiment provided by the present invention: an aluminum veneer with easily cleanable surface attachments, including an aluminum veneer main body 1. Installation ear plates 2 are provided at the bottoms of the four sides of the aluminum veneer main body 1. The installation ear plates 2 are connected to the aluminum veneer main body 1 by screws. Side slots 103 are provided on the surfaces of the four sides of the aluminum veneer main body 1. An inner support reinforcing rib 4 is provided inside the aluminum veneer main body 1. The inner support reinforcing rib 4 is connected to the installation ear plate 2 by screws. A gap connecting film 3 is provided between the inner support reinforcing rib 4 and the aluminum veneer main body 1. A fluorocarbon coating 101 is provided on the outer surface of the aluminum veneer main body 1, and an aerogel coating 102 is provided on the inner surface of the aluminum veneer main body 1;

[0037] The outer finish of the aluminum veneer main body 1 is processed by using the traditional fluorocarbon spraying technology. Fluorocarbon spraying has excellent anti-fading property, anti-frosting property, and corrosion resistance against atmospheric pollution. At the same time, dust and pollutants are also difficult to adhere to the surface, which is convenient for later cleaning. And an aerogel coating 102 is newly added to the inner finish of the aluminum plate. The coating of aerogel can effectively isolate the heat transfer to the inside of the aluminum plate when a building catches fire. Because the thermal decomposition reaction of fluorocarbon will produce harmful substances such as toxic phosgene and fluorocyclohexanol, and the aerogel can reduce the probability of thermal decomposition of the fluorocarbon coating 101 under the influence of continuous high temperature;

[0038] A group of gap connecting films 3 are installed around the aluminum veneer main body 1. During the assembly of the aluminum veneer, the gap connecting films 3 between the aluminum veneer main bodies 1 can be attracted and combined with each other by means of a magnetic attraction structure. In this way, a diaphragm can be formed between the gaps. The diaphragm can intercept the dust and sewage generated during cleaning and daily processes outside the diaphragm. And a cleaning coating will also be applied to the surface of the diaphragm, so as to avoid the accumulation of dust and sundries. And the entire diaphragm is located inside the aluminum veneer main body 1 and will not be affected by air flow and wind, which can prevent the diaphragm from being disconnected.

[0039] Please refer to Figures 5-6, the gap connecting film 3 includes a limit rubber plug 301, a sealing rubber strip 302, an extended edge film 303 and a magnet inlay edge 304. The limit rubber plug 301, the sealing rubber strip 302 and the extended edge film 303 are set as an integral structure. Among them, the sealing rubber strip 302 is arranged between the limit rubber plug 301 and the extended edge film 303. The magnet inlay edge 304 is connected to the extended edge film 303 through an adhesive. The limit rubber plug 301 is connected to the aluminum decorative board main body 1 through a side groove 103. The sealing rubber strip 302 fits on the surface around the aluminum decorative board main body 1. The gap connecting films 3 are connected by attracting and combining through the magnet inlay edges 304;

[0040] The limit rubber plug 301, the sealing rubber strip 302 and the extended edge film 303 are integrally cast by an injection molding process. The limit rubber plug 301 is located inside the side groove 103 around the aluminum single board. The limit rubber plug 301 is between the aluminum decorative board main body 1 and the inner support reinforcing rib 4. While achieving fixed support, it can also play a buffering role at the connection gap between the aluminum single board and the inner support reinforcing rib 4. The sealing rubber strip 302 fits on the surface around the aluminum single board, covering the entire side groove 103, preventing dust and moisture from entering the inside of the aluminum single board from the gap. The extended edge film 303 is used to connect the magnet inlay edge 304. In this way, the extended edge films 303 between the aluminum plates can achieve attracting and combining connection. The extended edge film 303 itself has strong stretchability and can also adapt to the physical properties of the metal structure after attracting and fixing.

[0041] In order to better show the production process of the aluminum single board with easily cleanable surface attachments, this embodiment proposes a production process of the aluminum single board with easily cleanable surface attachments, including the following steps:

[0042] Step 1: Punch the four sides of the cast aluminum single board, leaving two arc-shaped side grooves 103 on each side. Then polish its outer surface. After polishing, degrease and clean the outer surface, and finally perform chromizing treatment on the outer surface;

[0043] Step 2: After the chromizing treatment is completed, perform the spraying process of the primer. Preheat the fluorocarbon coating, control the temperature at 120 - 150 °C. After the temperature is qualified, atomize the fluorocarbon coating into extremely fine particles with a high-speed air flow and spray it onto the outer surface of the aluminum single board at a high speed to form a primer coating. The thickness of the primer coating is set at 5 - 7 μm;

[0044] Step 3: After the primer is sprayed, perform high-temperature baking, control the temperature at 225 - 235 °C. After the primer is dried, perform the spraying process of the topcoat. Pigments can be added according to the color requirements of the outer surface during the spraying of the topcoat. The thickness of the topcoat layer is set at 23 - 30 μm;

[0045] Step 4: After the topcoat is dried, apply the clear coat. The thickness of the clear coat is 5 - 10 μm. After the three layers of paint are cured, the entire single aluminum plate needs to be placed in a curing furnace for secondary curing. The secondary curing temperature is controlled at 180 - 250 °C, and the curing time is 15 - 25 min.

[0046] Step 5: After the exterior finish coating process is completed, perform heat insulation treatment on the interior surface of the single aluminum plate. First, spray a temperature-bearing coating material on the interior surface to prevent the aluminum plate surface from being exposed to the air. The thickness of the pre-coating is 5 - 8 μm.

[0047] Step 6: After the pre-coating is dried, apply the first coat of aerogel heat insulation coating, with the thickness controlled at 3 - 6 mm. After the first layer is dry, the thickness can be appropriately increased to 6 mm starting from the second layer, for a total of three layers.

[0048] Step 7: Place the entire single aluminum plate in an injection mold, inject natural latex into the interior of the mold. The latex passes through the side slot 103 and enters the inner side of the single aluminum plate. The latex cures and forms a gap connecting film 3 inside the mold.

[0049] Step 8: Fit a set of annular magnetic strips into the grooves around the extended edge film 303, then use UV curing glue to bond and fix the installation gap between the magnetic strips and the edge film. Finally, place the inner support reinforcing rib 4 on the inner side of the single aluminum plate and connect and fix it.

[0050] In Step 1, after punching, polish the burrs on the edge of the hole groove.

[0051] In Step 4, after the topcoat is sprayed, wait until the temperature drops to 70 - 80 °C before performing the clear coat spraying operation.

[0052] In Step 6, after the interior surface coating is dried and cured, place the interior surface of the single aluminum plate above a high-temperature detection device for heating, and collect and analyze the gas components in the exterior finish area to determine whether harmful gases are produced.

[0053] The next coat must be applied after the previous coat is completely dry.

[0054] After the aerogel heat insulation coating is cured, there are no visible oil, grease, and dirt on the surface, and there are no poorly adhered coatings, impurities, and foreign objects affecting adhesion.

[0055] Working principle: The outer surface of the aluminum veneer main body 1 is processed by using the traditional fluorocarbon spraying technology. Fluorocarbon spraying has excellent anti-fading property, anti-frosting property, and corrosion resistance against air pollution. At the same time, dust and pollutants are also difficult to adhere to the surface, which is convenient for later cleaning. And aerogel coating layer 102 is newly added to the inner surface of the aluminum plate. The coating of aerogel can effectively isolate the heat transfer to the inside of the aluminum plate when a building catches fire. Since the thermal decomposition reaction of fluorocarbon will produce harmful substances such as toxic phosgene and fluorocyclohexanol, aerogel can reduce the probability of thermal decomposition of the fluorocarbon coating 101 under the influence of continuous high temperature. A group of gap connecting films 3 are installed around the aluminum veneer main body 1. The gap connecting film 3 includes a limit rubber plug 301, a sealing rubber strip 302, an extended edge film 303, and a magnet inlay 304. The limit rubber plug 301, the sealing rubber strip 302, and the extended edge film 303 are integrally cast by using the injection molding process. The limit rubber plug 301 is located inside the side groove 103 around the aluminum single plate. The limit rubber plug 301 is between the aluminum veneer main body 1 and the inner support reinforcing rib 4. While achieving fixed support, it can also play a buffering role at the connection gap between the aluminum single plate and the inner support reinforcing rib 4. The sealing rubber strip 302 is attached to the peripheral surface of the aluminum single plate, covering the entire side groove 103, to prevent dust and moisture from entering the inside of the aluminum single plate from the gap. The extended edge film 303 is used to connect the magnet inlay 304. In this way, the extended edge films 303 between the aluminum plates can achieve suction connection. The extended edge film 303 itself has strong stretchability and can also adapt to the physical properties of the metal structure after suction fixation. During the assembly process of the aluminum single plate, the gap connecting films 3 between the aluminum veneer main bodies 1 can be sucked together by means of the magnetic attraction structure. In this way, a diaphragm can be formed between the gaps. The diaphragm can intercept the dust and sewage generated during cleaning and daily processes outside the diaphragm. And the surface of the diaphragm will also be coated with a cleaning coating to avoid the accumulation of dust and sundries. And the entire diaphragm is located inside the aluminum veneer main body 1 and will not be affected by air flow and wind, which can prevent the diaphragm from disconnecting.
