[0022] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be varied without departing from the scope of protection of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0023] In order to better understand the present invention, Figure 1-Figure 5 A composite filled lightweight decorative component of the utility model is described in detail.

[0024] Example 1:

[0025] like Figure 1-Figure 4 As shown, a composite filled lightweight decorative component includes: an aluminum alloy shell 100, the aluminum alloy shell 100 has a cavity 110, a lightweight filling unit 200 is arranged in the cavity 110, and the lightweight filling unit 200 is adhered to the cavity wall of the cavity 110, the lightweight filling unit 200 and the aluminum alloy shell 100 are combined to form the main body of the composite filled lightweight decorative component, a coating unit 300 is provided on the surface of the aluminum alloy shell 100, and the aluminum alloy shell 100 is connected to a connecting piece 400.

[0026] It should be noted that the aluminum alloy housing 100 is obtained by bending and welding. Before bending, it is necessary to use a CNC laser cutting machine to cut multiple flat plates from the aluminum alloy plate according to design requirements, and then bend the multiple flat plates to form a single aluminum alloy plate. For a single aluminum alloy plate with an arc surface, the arc portion can be formed by multi-point bending. Finally, the multiple aluminum alloy plates are assembled into the aluminum alloy housing 100 by welding. Through digital processing, the size standard of the aluminum alloy housing 100 is controllable and the error is small.

[0027] Aluminum alloy has good processing properties. After cutting, bending, welding and other processes, aluminum alloy plates can be formed into various forms of aluminum alloy housings 100, and then into composite filled lightweight decorative components with different shapes to meet different design requirements. The forming process of the aluminum alloy housing 100 is simple, the production time is short, and the production efficiency is high, thereby improving the production efficiency of composite filled lightweight decorative components.

[0028] The density of the aluminum alloy and the lightweight filling unit 200 is lower than that of cement. The resulting composite filling lightweight decorative component is much lighter than a cement component. For some relatively small composite filling lightweight decorative components, even one person can easily lift the composite filling lightweight decorative component (for example, a 1-meter-long composite filling lightweight decorative component can be easily picked up with just two fingers). This makes transportation and installation more convenient and quick. Even if the composite filling lightweight decorative component shakes or even falls, it will not cause serious work-related injuries.

[0029] In addition, aluminum alloy has high strength, good corrosion resistance, strong low-temperature resistance, is not easy to break, can maintain stability and stability for a long time, has low maintenance costs, and increases the service life of composite-filled lightweight decorative components. Cement decorative components are easily corroded, and the ornamental value of corroded cement decorative components is greatly reduced. In low-temperature environments, cement decorative components are also prone to freeze-thaw damage and other problems, which lead to breakage and need to be replaced or repaired, with high maintenance costs.

[0030] By using the composite filled lightweight decorative component of the present invention, since the weight of the aluminum alloy shell 100 and the lightweight filling unit 200 are both relatively small, the weight of the decorative component can be greatly reduced, which provides convenience for the installation of the decorative component and improves the safety of the decorative component installation process. The forming process of the aluminum alloy shell 100 and the lightweight filling unit 200 is mainly cutting and bending, and the forming speed is fast and the time consumption is shorter, which improves the production efficiency of the decorative component. In addition, the aluminum alloy shell 100 has the characteristics of high strength, good corrosion resistance, and strong low temperature resistance, which improves the service life of the decorative component and reduces the maintenance cost of the decorative component.

[0031] Example 2:

[0032] As an optimization of Example 1, the thickness of the aluminum alloy housing 100 is 1-5 mm.

[0033] It should be noted that by controlling the thickness of the aluminum alloy shell 100 to 1-5 mm, the aluminum alloy shell 100 formed after bending is more delicate and exquisite at the bending part, with clear edges and corners, and the produced composite filled lightweight decorative components are also more delicate and beautiful. In addition, the thickness of the aluminum alloy shell 100 is relatively thin, which can reduce the production cost of the composite filled lightweight decorative components.

[0034] Example 3:

[0035] As a further optimization of Example 2, Figure 2-Figure 4 As shown, the lightweight filling unit 200 includes a filling foam 210 . The filling foam 210 is disposed in the cavity 110 . The filling foam 210 is used to fill the cavity 110 .

[0036] It should be noted that although aluminum alloy has a high specific strength, when the aluminum alloy shell 100 is used alone, its impact resistance and energy absorption performance are insufficient. The filling foam 210 has low density, high energy absorption and good impact resistance. The porous structure inside the filling foam 210 can effectively disperse and absorb impact energy. However, when the filling foam 210 is used alone, due to its high porosity, its bearing capacity and stiffness are relatively low; when the filling foam 210 is filled into the aluminum alloy shell 100, the two form a composite structure. This structure combines the rigidity of aluminum alloy and the energy absorption of the filling foam 210, forming a complementary advantage. When subjected to external force, the filling foam 210 deforms and absorbs energy, and distributes the stress borne by the aluminum alloy shell 100 to a larger area, reducing local pressure, reducing stress concentration in the aluminum alloy shell 100, and reducing the possibility of local deformation of the aluminum alloy shell 100 when subjected to external force, thereby increasing the overall anti-deformation ability and improving the bearing capacity and service life of the composite filled lightweight decorative component.

[0037] In this embodiment, the material of the filling foam 210 is polystyrene. Polystyrene foam is a light polymer. It is made by adding a foaming agent to polystyrene resin and heating it to soften it, generating gas to form a foam plastic with a hard closed-cell structure. The polystyrene foam is CNC cut to cut into the required shape to obtain the polystyrene filling foam 210. The polystyrene filling foam 210 can be processed and manufactured in a factory to realize assembly line production, thereby reducing the production cost of the polystyrene filling foam 210.

[0038] Example 4:

[0039] As a further optimization of Example 3, Figure 2-Figure 4 As shown, the filling unit further includes a foaming layer 220 , which is located between the aluminum alloy shell 100 and the filling foam 210 .

[0040] It should be noted that the foaming layer 220 is obtained by foaming the foam glue. Before installing the filling foam 210, a proper amount of foam glue is sprayed on the cavity wall of the cavity 110, and then the filling foam 210 is placed in the cavity 110, and the opening of the cavity 110 is blocked to prevent the filling foam 210 from being squeezed out during the foaming process of the foam glue. The foam glue foams to form the foaming layer 220, and the foaming layer 220 can fill the irregular parts in the cavity 110, thereby reducing the requirements for the morphological structure of the filling foam 210 and reducing the filling foam. 210 production cost; the foaming process of the foam glue will squeeze the filling foam 210, and the foaming layer 220 and the filling foam 210 will fill the entire cavity 110 together, and the foaming layer 220 will be bonded together with the aluminum alloy shell 100 and the filling foam 210, so that the three are tightly combined, and this combination helps to effectively combine the energy absorption characteristics of the filling foam 210 and the rigidity characteristics of the aluminum alloy shell 100, forming a composite structure with better overall performance, thereby improving the bearing capacity of the composite filled lightweight decorative component.

[0041] In this embodiment, the foam glue is polyurethane foam glue, which is an environmentally friendly material with little pollution to the environment. Polyurethane foam glue has super strong self-adhesive properties. The formed polyurethane foam layer 220 can be firmly bonded to the aluminum alloy shell 100 and the filling foam 210 without any intermediate adhesive material. The polyurethane foam layer 220 also has good shock absorption and cushioning properties, which can improve the overall anti-deformation ability.

[0042] Example 5:

[0043] As an optimization of Example 4, Figure 4 and Figure 5 As shown, the coating unit 300 includes a primer layer 310 and a decorative paint layer 320 . The primer layer 310 is disposed on the outer surface of the aluminum alloy housing 100 , and the decorative paint layer 320 is disposed on a side of the primer layer 310 away from the aluminum alloy housing 100 .

[0044] It should be noted that the decorative paint layer 320 can improve the ornamental value of the composite-filled lightweight decorative component. The primer can be applied to the surface of the aluminum alloy shell 100 by spraying, brushing, etc. The formed primer layer 310 can seal the tiny pores on the surface of the aluminum alloy shell 100, improve the surface condition of the aluminum alloy shell 100, provide a good foundation for the decorative paint layer 320, enhance the adhesion between the aluminum alloy shell 100 and the decorative paint layer 320, prevent the decorative paint layer 320 from falling off or peeling off, and reduce maintenance costs.

[0045] In this embodiment, the material of the primer layer 310 is solvent-free epoxy primer. The solvent-free epoxy primer mainly uses modified epoxy resin as the main film-forming material and uses active diluent toughening agent to achieve solvent-freeness, giving the coating unit 300 good adhesion, excellent chemical stability and mechanical properties.

[0046] Example 6:

[0047] As a further optimization of Example 5, the decorative paint layer 320 is made of oil-based paint.

[0048] It should be noted that the decorative paint layer 320 can be sprayed or brushed with oil-based paints such as fluorocarbon paint and polyurethane paint. The oil-based paint has bright colors and high saturation, which can make the composite filled lightweight decorative components more ornamental. The oil-based paint has good wear resistance and weather resistance and is not easy to fade. The coating film formed by the oil-based paint is strong and can maintain its appearance and functionality for a long time, reducing maintenance costs. In addition, the raw materials and production processes of oil-based paint are relatively mature, and the market price is relatively low, which is conducive to reducing the production cost of composite filled lightweight decorative components.

[0049] Example 7:

[0050] As a further optimization of Example 6, Figure 5 As shown, the coating unit 300 further includes a protective layer 330 , which is disposed on a side of the decorative paint layer 320 away from the primer layer 310 .

[0051] It should be noted that, for composite-filled lightweight decorative components installed on the exterior walls of buildings, the protective layer 330 can be formed by spraying or brushing a protective agent, thereby enhancing the waterproof and anti-fouling properties of the composite-filled lightweight decorative components. For composite-filled lightweight decorative components installed indoors, the protective layer 330 can be formed by spraying or brushing a topcoat to prevent the decorative paint layer 320 from oxidizing and fading, thereby reducing maintenance costs. According to different installation design requirements, suitable materials are selected to form the protective layer 330, which can provide different protection for the decorative paint layer 320 and improve the service life of the composite-filled lightweight decorative components.

[0052] Example 8:

[0053] As a further optimization of Example 7, the connector 400 is connected to the aluminum alloy housing 100 by bonding, riveting or welding.

[0054] It should be noted that, for composite filled lightweight decorative components of smaller size, the connector 400 is connected to the aluminum alloy shell 100 by bonding, which is quick and convenient, and the installation of the connector 400 will not cause damage to the aluminum alloy shell 100; for composite filled lightweight decorative components of medium size, the connector 400 is connected to the aluminum alloy shell 100 by riveting. At the same time, when a flat plate is cut out on the aluminum alloy plate, a hole cutting process is required to reduce the damage caused by the rivets to the aluminum alloy shell 100 during the riveting process. The connector 400 is fixed to the aluminum alloy shell 100 by rivets, and the connection is more secure; for composite filled lightweight decorative components of larger size, the connector 400 is connected to the aluminum alloy shell 100 by welding. The connecting piece 400 is connected to the aluminum alloy shell 100 in a connection manner. The connection strength between the connecting piece 400 and the aluminum alloy shell 100 is high, the connecting piece 400 will not fall off, and the material of the connecting piece 400 is also aluminum alloy, so as to avoid the poor compatibility between the connecting piece 400 and the aluminum alloy shell 100, which affects the firmness of the welding between the two. This method requires that the connecting piece 400 be welded to the aluminum alloy shell 100 first, and then the entire piece is ground and polished before the coating unit 300 can be coated. If the coating unit 300 is coated first, the coating unit 300 will affect the welding of the connecting piece 400, resulting in a reduction in the connection strength between the connecting piece 400 and the aluminum alloy shell 100, and the coating unit 300 will be damaged during the welding process.

[0055] The above describes an embodiment of the utility model in conjunction with the accompanying drawings, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms without departing from the purpose of this embodiment and the scope of protection of the claims, all of which are protected by this embodiment.
