Description

Technical Field

[0001] The utility model relates to the technical field of aluminum materials, and particularly relates to an explosion-proof aluminum material with high temperature resistance. Background Art

[0002] Aluminum materials refer to products made of aluminum and other alloy elements. Usually, they are first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then processed through processes such as cold bending, sawing, drilling, assembling, and coloring. By adding a small amount of one or several alloy elements, such as magnesium, silicon, manganese, copper, zinc, iron, chromium, titanium, etc., aluminum alloys with different properties can be obtained. The aluminum alloys are further strengthened and hardened through cold processing and heat treatment, and their tensile strength is greatly improved. Currently, conventional aluminum plates cannot be used in high-temperature environments. As the temperature rises, there is a possibility that the aluminum plates will crack, resulting in the splashing of aluminum plate fragments and causing losses to property or personal safety.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , this utility model provides a high-temperature resistant explosion-proof aluminum material, including an aluminum shell 1 and an aluminum plate 2. Carbon fiber backing cloth 3 is adhered to both sides of the aluminum plate 2. The aluminum shell 1 is adhered to the surface of the carbon fiber backing cloth 3, and the edge of the aluminum shell 1 wraps the side edge of the aluminum plate 2. A convex part 4 is integrally formed on the side of the aluminum plate 2, and the edge of the aluminum shell 1 abuts against the surface of the convex part 4. High-temperature resistant structures are provided on the surfaces of the aluminum plate 2 and the aluminum shell 1. The high-temperature resistant structure includes a heat-resistant layer 5 and an anti-corrosion layer 6. The heat-resistant layer 5 is provided on the surfaces of the aluminum shell 1 and the aluminum plate 2, and the anti-corrosion layer 6 is provided on the surface of the heat-resistant layer 5.

[0018] Please refer to Figure 1 and 2, a convex portion 4 is integrally formed on the side surface of the aluminum plate 2, and the aluminum plate 2 can be directly in contact with the outside world. Such a design can increase the material rigidity while also serving as a heat dissipation structure. The setting of the high-temperature resistant structure greatly increases the high-temperature resistant performance of the aluminum shell 1 and the aluminum plate 2. When either the aluminum shell 1 or the aluminum plate 2 is cracked by burning, the carbon fiber pad cloth 3, as the connecting material between the two, is a flexible material and is bonded to both the aluminum shell 1 and the aluminum plate 2. Therefore, when the aluminum shell 1 or the aluminum plate 2 is cracked by burning, the carbon fiber pad cloth 3 remains in a bonded state with the fragments of the aluminum shell 1 or the aluminum plate 2, thus preventing the fragments of the aluminum shell 1 or the aluminum plate 2 from splashing.

[0019] Specifically, the carbon fiber pad cloth 3 can serve as a buffer structure between the aluminum shell 1 and the aluminum plate 2, and the carbon fiber pad cloth 3 itself also has the performance of being resistant to high temperatures. For the aluminum shell 1 and the aluminum plate 2, their surfaces are bonded through the flexible carbon fiber pad cloth 3. When the aluminum shell 1 or the aluminum plate 2 is cracked by burning, the crack will only appear on the surface of the aluminum shell 1 or the aluminum plate 2, and the aluminum shell 1 and the aluminum plate 2 are still in a bonded state with the carbon fiber pad cloth 3, which makes the aluminum shell 1 and the aluminum plate 2 not splash.

[0020] The heat-resistant layer 5 is set as a lead phosphate powder coating, and the anti-corrosion layer 6 is set as a fluorocarbon resin coating. The lead phosphate powder coating is sprayed on the surfaces of the aluminum shell 1 and the aluminum plate 2, and the fluorocarbon resin coating is sprayed on the surface of the lead phosphate powder coating. The thickness ratio of the lead phosphate powder coating to the fluorocarbon resin coating is 1:1.

[0021] Please refer to Figure 3 , because the lead phosphate powder coating has good high-temperature resistant performance, can remain stable in a high-temperature environment, and is tightly combined with the substrate and is not easy to peel off. Therefore, as the heat-resistant layer 5 directly in contact with the aluminum shell 1 and the aluminum plate 2, it improves the high-temperature resistant performance of the aluminum shell 1 and the aluminum plate 2. And because the fluorocarbon resin coating has good tolerance to most chemicals and solvents, can be exposed to the outdoor environment for a long time without fading or peeling, and has an extremely low surface tension, is not easy to adsorb dust and pollutants, and is easy to clean. Therefore, it is used as the outermost layer of the aluminum shell 1 and the aluminum plate 2, improving the corrosion-resistant performance of the aluminum shell 1 and the aluminum plate 2. Moreover, the lead phosphate powder coating and the fluorocarbon resin coating are only one of the methods to improve the overall heat resistance and corrosion resistance. In this embodiment, the thickness ratio of the two is set to 1:1 in order to avoid the need to repeatedly adjust parameters during spraying and only need to change the type of coating, so as to facilitate the spraying process.

[0022] The side surface of the convex portion 4 is flush with the side surface of the aluminum shell 1, and the carbon fiber pad cloth 3 is bonded to both the aluminum shell 1 and the aluminum plate 2 through an inorganic adhesive.

[0023] Please refer to Figure 2, the inorganic adhesive has high-temperature resistance, enabling the carbon fiber backing cloth 3 to remain bonded to the aluminum shell 1 and the aluminum plate 2 in a high-temperature environment.

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
