Description

Technical Field

[0001] The present invention relates to the technical field of aluminum veneer panels, and more particularly to an easy-to-clean and anti-fouling aluminum veneer panel and a production process thereof. Background Art

[0002] Aluminum veneer, a specially treated architectural material, is widely used on exterior surfaces such as roofs and walls. Because it's exposed to the elements, it's often coated to prolong its finish. One such coating, a titanium dioxide water-soluble sol, forms a transparent, inorganic film with environmentally friendly properties such as self-cleaning, anti-aging properties, and photocatalytic degradation of organic matter when applied to the desired protective substrate at room temperature. The self-cleaning mechanism is as follows: Upon exposure to light, titanium dioxide generates electrons and holes, which react with water and oxygen in the air to produce hydroxyl radicals and oxygen radicals capable of decomposing various organic matter and bacteria, forming a super-hydrophilic film. After decomposition, oil stains are easily washed away by rain, achieving a self-cleaning effect. The thickness of the titanium dioxide water-soluble sol coating on the aluminum veneer determines its effective protection duration. Currently, using direct spraying, the coating can only be applied to a thickness of less than 0.1 mm. Summary of the Invention

[0007] The present invention is further configured such that the straight portions and the curved portions are alternately arranged along a direction perpendicular to the length of the end face.

[0008] The present invention is further configured such that the antifouling layer is a titanium dioxide water-soluble sol coating.

[0009] The present invention also adopts the following technical solution: a production process for easy-to-clean anti-fouling aluminum veneer, comprising an upper template and a lower template, the upper template being movable up and down, the lower template being provided with a first groove body, the upper template being slidably connected with a lifting plate, the lifting plate being inserted into the upper template and being movable up and down along the inner wall of the upper template, a shaping layer being installed at the bottom of the lifting plate, a plug hole and a second channel being respectively provided on both sides of the upper template, the plug hole being capable of being inserted with an insert cylinder to close the plug hole, the insert cylinder being capable of moving left and right, the channel being connected with the first channel, the channel being capable of being inserted with an injection cylinder, the injection cylinder being capable of closing the second channel, the injection cylinder being capable of moving left and right, the lower template being provided with a channel, the upper template being provided with a third groove body, the groove body being connected with the channel and the plug hole, and the channel being externally connected with a vacuum pump;

A forming cavity is formed between the bottom of the shaping layer and the top of the aluminum plate. The two sides of the forming cavity are connected to the insertion hole and the second channel respectively;

[0012] ②The lifting plate moves downward to make the bottom surface of the shaping layer fit the upper surface of the aluminum plate, so that the gas in the molding cavity is discharged to the outside through the jack and the channel;

[0013] ③ The insert is inserted into the jack, and a gap is formed between the right end of the insert and the molding cavity. The molding cavity is connected to the channel. The injection cylinder is inserted into the channel one to close the channel two. The lifting plate moves upward to form a molding cavity between the bottom of the shaping layer and the top of the aluminum plate. The vacuum pump is turned on to extract the gas in the molding cavity.

[0014] ④ The insert cylinder moves to the right and abuts against the shaping layer and the aluminum plate to close one side of the molding cavity. The injection cylinder moves to the right to open the second channel. The injection cylinder injects the anti-fouling coating into the second channel to form the anti-fouling layer in the molding cavity.

[0015] ⑤ After the anti-fouling coating is hardened under pressure in the molding cavity, the insert cylinder is pulled out of the socket, the injection cylinder is pulled out of the channel one, and the upper template moves upward to separate from the lower template to take out the aluminum plate coated with the anti-fouling layer.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The curved portion is provided with a second raised portion, which is embedded in a recessed portion to enhance the adhesion of the anti-fouling layer to the end surface. Furthermore, by controlling the molding process in the molding cavity between the upper and lower mold plates, the thickness of the anti-fouling layer can reach 0.2mm, increasing the reactive capacity of the anti-fouling layer and extending the protection period of the anti-fouling layer on the aluminum plate.

[0022] 2. By reducing the air in the molding cavity, it is not easy to form bubbles in the anti-fouling layer coating squeezed into the molding cavity during the molding process, the coating distribution is more uneven, and the overall molding quality is improved.

[0023] 3. Since the air in the forming cavity is exhausted once through the downward squeezing of the shaping layer, the air inside the forming cavity is greatly reduced when the lifting plate moves upward and is formed again between the bottom of the shaping layer and the top of the aluminum plate, thereby reducing the vacuum pumping time and improving the process efficiency.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1:

[0035] like Figures 1-4 As shown, this embodiment discloses an easy-to-clean anti-fouling aluminum single plate, comprising an aluminum plate 1 and an anti-fouling layer 2, wherein the aluminum plate 1 is a long plate structure. Figure 1 、 Figure 2 As shown, the aluminum plate 1 includes an end surface 11 at the top, and the end surface 11 is provided with a raised portion 111, which is raised upward along the upper end of the end surface 11 and is combined with Figure 3 、 Figure 4 The raised portion 111 is arranged along the length of the end surface 11. There are multiple raised portions 111 and they are spaced apart. The raised portion 111 is provided with five recessed portions 1111. The recessed portions 1111 are recessed downward along the upper wall of the raised portion 111. The recessed portions 1111 are arranged along the length of the raised portion 111.

[0036] like Figure 1 、 Figure 2 As shown, the end face 11 is coated with an antifouling layer 2, which is a titanium dioxide water-soluble sol coating. The bottom surface of the antifouling layer 2 is bonded to the end face 11. The antifouling layer 2 includes a straight portion 21 and a curved portion 22, which are arranged alternately along a direction perpendicular to the length of the end face 11. The curved portion 22 is provided with a second raised portion 221, which is embedded in a recessed portion 1111 to enhance the adhesion of the antifouling layer 2 to the end face 1. This allows the thickness of the antifouling layer 2 to reach 0.2 mm, increasing the reactive amount of the antifouling layer 2 and improving the protective effect of the antifouling layer 2 on the aluminum plate.

[0037] like Figure 1 、 Figure 2As shown, the straight portion 21 is flat on the side away from the end face 11, while the curved portion 22 is a convex arc surface on the side away from the end face 11. The thickness of the straight portion 21 is greater than that of the curved portion 22. When the aluminum plate 1 is laid flat, the curved portion 22 acts as a flow collector, allowing dirt to react with the anti-fouling layer 2 and be easily washed away by water, thereby restoring a smooth surface.

[0038] Example 2:

[0039] like Figure 5-Figure 8 As shown, a production process of aluminum veneer is used to process the easy-to-clean and anti-fouling aluminum veneer of embodiment 1, and the production process includes process equipment. Figure 5 As shown, the process equipment includes an upper template 4 and a lower template 3. The top of the upper template 4 is connected to a driving component 6 to enable it to move up and down. The driving component 6 is a cylinder.

[0040] like Figure 5 As shown, the upper mold plate 4 is open at the bottom, and a lifting plate 5 is slidably connected to the upper mold plate 4. The lifting plate 5 is inserted into the upper mold plate 4. A driving component 1 51 is mounted on the top of the lifting plate 5, enabling the lifting plate 5 to move up and down along the inner wall of the upper mold plate 4. Driving component 1 51 is a hydraulic cylinder, and a proportional valve with a servo function is used for high stroke accuracy. Mounting bracket 52 is mounted on the upper mold plate 4, and mounting bracket 52 is mounted on the driving component 1 51. The upper mold plate 4 is provided with a groove 2 41 for the pipeline of driving component 1 51 to pass through.

[0041] like Figure 5 、 Figure 6 As shown, a shaping layer 53 is installed at the bottom of the lifting plate 5. The shaping layer 53 is made of rubber. The outer wall of the shaping layer 53 is in close contact with the inner wall of the upper template 4 to form a seal. The bottom surface of the shaping layer 53 has the same shape as the top surface of the anti-fouling layer 2.

[0042] like Figure 5 As shown, the lower mold plate 3 is provided with a groove 1 32, which is used to place the aluminum plate 1. The upper mold plate 4 and the lower mold plate 3 are pressed together to form a closed space between them. A gasket 82 is also installed at the joint between the upper mold plate 4 and the lower mold plate 3 for sealing. After the aluminum plate 1 is inserted into the groove 1 32 and the upper mold plate 4 and the lower mold plate 3 are pressed together, a forming cavity 10 is formed between the bottom of the shaping layer 53 and the top of the aluminum plate 1. The anti-fouling coating 2 is filled into the forming cavity 10.

[0043] like Figure 5 、 Figure 6As shown, the left side of the lower mold plate 3 is provided with a channel 31, and the upper mold plate 4 is provided with a groove body 3 42, which is connected to the channel 31. The channel 31 is externally connected to a vacuum pump 7, and the groove body 3 42 is connected to the molding cavity 10. The left side of the upper mold plate 4 is provided with a socket 44, which is connected to the groove body 3 42. The socket 44 can be inserted with an insert 81 to close the socket 44. The insert 81 is connected to the drive component 3 8 to achieve left and right movement. The drive component 3 8 is an electric cylinder. When the insert 81 leaves the socket 44, the socket 44 is connected to the outside world, as shown in FIG. Figure 7 As shown, when the insert 81 is inserted into the insertion hole 44 and not moved to the rightmost end, the groove body 42, the molding cavity 10, and the channel 31 are connected, which facilitates the vacuum pump 7 to evacuate the molding cavity 10. Since the molding cavity 10 has a height of less than 0.2 mm, when there is a lot of air in the molding cavity 10, the anti-fouling layer 2 coating is easily formed during the process of being squeezed into the molding cavity 10, resulting in bubbles and pits, causing uneven distribution of the coating and affecting the molding quality. Therefore, the vacuum pump 7 needs to be used to squeeze out the air.

[0044] like Figure 5 、 8 As shown, a channel 1 43 is provided on the right side of the upper template 4, and a channel 2 431 is connected to the left side of the channel 1 43, and the channel 2 431 is connected to the molding cavity 10. The channel 2 431 is coaxial with the channel 1 43, and the aperture of the channel 1 43 is larger than that of the channel 2 431. The syringe 91 can be inserted into the channel 1 43, and the syringe 91 can close the channel 2 431. Specifically, the syringe 91 can move left and right under the drive of the driving component 4 9, and the syringe 91 can be pulled out of the channel 1 43 to the right. The syringe 91 is provided with an injection cavity 92, and the injection cavity 92 is connected to the drainage hole 93. The end of the injection cavity 92 away from the drainage hole 93 is closed by a cover plate 94. The upper end of the injection cavity 92 is connected to the injection plug 921 and is externally connected to an injection machine for performing the coating injection operation of the anti-fouling layer 2.

[0045] When the injection cylinder 91 abuts against the bottom surface of channel 1 43 , the drainage hole 93 is disconnected from channel 2 431 ; when the injection cylinder 91 is separated from the bottom surface of channel 1 43 and the injection cylinder 91 is located in channel 1 43 , the drainage hole 93 can be connected with channel 2 431 , so that the paint in the injection cavity 92 can be injected into the molding cavity 10 .

[0046] The specific process steps are:

[0047] ① The upper mold plate 4 moves upward to separate from the lower mold plate 3. The aluminum plate 1 is inserted into the groove body 32, and the outer wall of the aluminum plate 1 is aligned with the inner wall of the groove body 32. The upper mold plate 4 moves downward to press the upper mold plate 4 and the lower mold plate 3 together. The two sides of the molding cavity 10 are connected to the insertion hole 44 and the second channel 431 respectively.

[0048] ② The lifting plate 5 moves downward so that the bottom surface of the shaping layer 53 is in contact with the upper end surface of the aluminum plate 1, so that the gas in the molding cavity 10 is discharged to the outside through the insertion hole 44 and the second channel 431;

[0049] ③ Insert the insert 81 into the insertion hole 44, and a gap is formed between the right end of the insert 81 and the molding cavity 10 (i.e. Figure 7 (See the state shown). At this point, the molding cavity 10 is connected to the channel 31, the syringe 91 is inserted into the channel 1 43 to seal the channel 2 431, the lifting plate 5 moves upward to form the molding cavity 10 between the bottom of the shaping layer 53 and the top of the aluminum plate 1, and the vacuum pump 7 is turned on to evacuate the air from the molding cavity 10. Because the downward pressure of the shaping layer 53 completes the initial expulsion of air from the molding cavity 10, the air in the molding cavity 10 formed again between the bottom of the shaping layer 53 and the top of the aluminum plate 1 as the lifting plate 5 moves upward is greatly reduced, reducing the vacuum pump 7's evacuation time and improving process efficiency.

[0050] ④ The insert cylinder 81 moves rightward to the rightmost end and contacts the shaping layer 53 and the aluminum plate 1 to close the left side of the molding cavity 10. The injection cylinder 91 moves rightward to open the second channel 431, thereby connecting the second channel 431 with the drainage hole 93. The anti-fouling layer 2 coating is injected into the second channel 431 through the injection cylinder 91 to form the anti-fouling layer 2 in the molding cavity 10.

[0051] ⑤ After the anti-fouling layer 2 coating is hardened under pressure in the molding cavity 10, the insert 81 is pulled out of the socket 44, the injection cylinder 91 is pulled out of the channel 1 43, and the upper template 4 moves upward to separate from the lower template 3 to take out the aluminum plate 1 coated with the anti-fouling layer 2.

[0052] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
