Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum profile technology, and in particular to a color-coated decorative aluminum profile. Background Technology
[0002] Aluminum profiles, as an important application of aluminum alloys, are produced through processes such as hot melting and extrusion of aluminum rods, ultimately forming aluminum materials with specific cross-sectional shapes. These materials are widely used in many fields such as construction, automobiles, and aerospace.
[0003] For example, Chinese utility model patent CN217268591U discloses a high-strength decorative aluminum profile, including a central aluminum tube, a fixing and reinforcing tube embedded in the inner side of the central aluminum tube, a central sound-absorbing cotton rod filled in the inner side of the fixing and reinforcing tube, an aluminum profile corner block connected to the outer side of the central aluminum tube, a connecting groove provided in the inner side of the aluminum profile corner block, a filling groove opened in the inner side of the aluminum profile corner block, and a sound-absorbing strip filled in the inner side of the filling groove.
[0004] In existing technologies, most rectangular hollow profiles have insufficient mechanical properties and weak resistance to complex loads. In typhoon and large-span curtain wall scenarios, they are prone to frame distortion and central tube dent due to wind pressure. Furthermore, the impact and compression of external forces directly act on the frame or center, leading to corner cracking and central tube instability, making them unable to withstand the continuous action of multi-directional composite loads. Utility Model Content

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, the external load first acts on the reinforcing frame, and is transmitted to the anti-compression frame through the anti-compression strip, dispersing the concentrated stress into annular stress. The support strip, the connecting frame, and the support frame work together to resist the shear deformation of the frame.

[0015] 2. In this utility model, the post-treatment layer adopts a semi-honeycomb continuous bridge arch structure, which improves wind pressure resistance while reducing weight. The topcoat layer is made by mixing polyvinylidene fluoride coating with graphene flakes to improve weather resistance and surface hydrophobicity. The primer layer contains an elastomer, which is a polyurethane-carbon nanotube composite material to improve thermal expansion performance. Silver nitrate nanoparticles are deposited on the surface of the anodic oxide layer by AC electrolysis to form a metal deposition layer, forming a dual-functional interface of photocatalysis and antibacterial properties to decompose harmful gases. The substrate layer is made of aluminum alloy material with titanium alloy reinforcement material on the surface to enhance tensile strength.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a color-coated decorative aluminum profile, including an aluminum profile assembly 1. The aluminum profile assembly 1 includes a central support cylinder 11 and a reinforcing frame 16. Four first reinforcing ribs 14 are fixedly connected to the outer side of the central support cylinder 11, arranged in a uniform ring around the center line of the central support cylinder 11. The other end of each first reinforcing rib 14 is fixedly connected to a corner of the reinforcing frame 16. Support strips 13 are fixedly connected to the other two opposite corners of the reinforcing frame 16. A reinforcing mechanism 2 is installed inside the reinforcing frame 16, including an anti-compression strip. 23 and compression frame 24, the four corners of the compression frame 24 are fixedly connected to one end of the four compression strips 23 respectively, and the other end of the four compression strips 23 are fixedly connected to the inner corner of the reinforcing frame 16; a filling cavity 17 is opened on the inner side of the middle support cylinder 11, and a reinforcing tube 12 is provided in the middle of the filling cavity 17; a second reinforcing rib 15 is provided on both sides of the first reinforcing rib 14, and the two ends of the second reinforcing rib 15 are fixedly connected to the outer side of the middle support cylinder 11 and the outer side of the reinforcing frame 16 respectively; a connecting frame 21 is fixedly connected between two adjacent support strips 13, and a support frame 22 is fixedly connected inside the connecting frame 21.
[0025] External loads are first applied to the reinforcing frame 16 and then transmitted to the compression frame 24 through the compression strip 23, dispersing the concentrated stress into annular stress. At the same time, the support strip 13 works in conjunction with the connecting frame 21 and the support frame 22 to resist the shear deformation of the frame. The radial load is transmitted obliquely to the central support cylinder 11 through the second reinforcing rib 15, utilizing the torsional resistance of its cylindrical structure to disperse the radial force. The first reinforcing rib 14 assists in converting the radial force into annular tension, preventing the central support cylinder 11 from becoming locally unstable under pressure. The reinforcing tube 12 is installed in the filling cavity 17, which is filled with vibration-damping material to improve axial compressive strength, forming a three-dimensional force system to achieve layered transmission and dispersion of force.
[0026] Example 2: Figure 1 and Figure 5 As shown, the aluminum profile assembly 1 also includes a post-treatment layer 101. A topcoat layer 102 is compositely connected to the inner side of the post-treatment layer 101. A primer layer 103 is compositely connected to the inner side of the topcoat layer 102. A pre-treatment layer 104 is compositely connected to the inner side of the primer layer 103. A substrate layer 105 is compositely connected to the inner side of the pre-treatment layer 104. An elastomer 106 is fixedly connected to the inner side of the primer layer 103. A thermochromic microcapsule 107 is disposed inside the substrate layer 105. The pre-treatment layer 104 includes a metal deposition layer 108 and an anodized layer 109. One side of the metal deposition layer 108 is compositely connected to one side of the anodized layer 109.
[0027] The post-treatment layer 101 is coated with a colored coating to ensure the long-term stability of the decorative effect of the aluminum profile component 1. The post-treatment layer 101 adopts a semi-honeycomb continuous arch structure inside, which improves wind pressure resistance while reducing weight. The topcoat layer 102 is made by mixing polyvinylidene fluoride coating with graphene flakes to improve weather resistance and surface hydrophobicity. The primer layer 103 contains an elastomer 106, which is a polyurethane-carbon nanotube composite material to improve thermal expansion performance. The pre-treatment layer 104 includes an anodized layer 1. 09 and metal deposition layer 108: Silver nitrate nanoparticles are deposited on the surface of anodic oxide layer 109 by alternating current electrolysis to form metal deposition layer 108, forming a dual-functional interface of photocatalysis and antibacterial, which can decompose harmful gases. The substrate layer 105 is made of aluminum alloy material and the surface is reinforced with titanium alloy material to enhance tensile strength. The thermochromic microcapsules 107 are set inside the substrate layer 105. When the ambient temperature exceeds 40°C, the thermochromic microcapsules 107 rupture to release phase change material, absorb heat and maintain the surface temperature of the profile stable.
[0028] The device's operation and working principle are as follows: The aluminum profile assembly 1 is sequentially configured with a post-treatment layer 101, a topcoat layer 102, a primer layer 103, a pre-treatment layer 104, and a substrate layer 105. The post-treatment layer 101 employs a semi-honeycomb continuous arch structure, reducing weight while improving wind pressure resistance. The topcoat layer 102 is made by mixing polyvinylidene fluoride coating with graphene flakes, improving weather resistance and surface hydrophobicity. The primer layer 103 contains an elastomer 106, a polyurethane-carbon nanotube composite material, improving thermal expansion performance. The pre-treatment layer 104 includes an anodized layer 109 and a metal deposition layer 108. Silver nitrate nanoparticles are deposited on the surface of the anodized layer 109 using AC electrolysis to form the metal deposition layer 108, creating a photocatalytic and antibacterial dual-functional interface capable of decomposing harmful gases. The substrate layer 105 is made of aluminum alloy with a surface reinforced with titanium alloy. The material enhances tensile strength. Thermochromic microcapsules 107 are set inside the substrate layer 105. When the ambient temperature exceeds 40°C, the thermochromic microcapsules 107 rupture and release phase change material, absorb heat and maintain the surface temperature of the profile. When the aluminum profile structure is subjected to external mechanical loads, the reinforcing frame 16, as the outermost load-bearing structure, is the first to come into contact with the load. The internal anti-compression strip 23 immediately transfers the concentrated stress to the anti-compression frame 24. The single-point impact force is dispersed into circumferential stress through the ring structure of the frame, avoiding local deformation of the frame. The support strip 13 and the support frame 22 in the connecting frame 21 work together to resist the shear deformation of the frame using the grid structure. The force is transmitted to the central support cylinder 11 at a 45° angle through the second reinforcing rib 15. The radial force is converted into circumferential tension by the anti-torsional characteristics of the cylindrical structure. The first reinforcing rib 14 helps to share the load. The reinforcing tube 12 and the vibration-resistant material further improve the axial compressive strength.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
