Description

Technical Field

[0001] The invention belongs to the technical field of composite board materials, in particular to an ultra-light composite material structural board. Background Art

[0002] As the construction industry's requirements for energy conservation, environmental protection, structural performance and construction efficiency continue to increase, the innovation and development of building materials has become one of the key factors in improving building quality and performance. Traditional building structural panels are mostly made of steel, concrete, wood and other materials. Although these materials perform well in terms of bearing capacity and durability, they have many limitations in terms of weight, transportation costs, construction efficiency, etc. For example, the weight of steel and concrete structural panels is large, which leads to transportation difficulties and high transportation costs, while increasing the labor intensity and construction period during the construction process.

[0003] In order to solve this problem, in recent years, the research on lightweight building materials has gradually become a hot topic in the field of building materials. Ultra-light composite structural panels, as a new type of building material, have the advantages of light weight, high strength, corrosion resistance, sound insulation and heat insulation, and have gradually attracted attention and application in the construction industry. Composite materials are made of two or more different materials combined by physical or chemical methods, which can give play to the characteristics of different components to achieve excellent comprehensive performance.

[0004] At present, some composite structural panels have been used in the construction field. However, the existing ultra-light composite structural panels still have many problems in terms of material combination, production process, structural optimization, etc. For example, the impact resistance, high temperature resistance and stability of traditional composite panels in long-term use still need to be improved. In addition, the production process of existing materials is often complicated and costly, making it difficult to apply them on a large scale in actual construction projects.

[0005] Therefore, developing an ultra-light composite structural panel with better performance, simpler production process and lower production cost has become a technical problem that needs to be urgently solved in the construction industry. Summary of the invention

[0022] The drawings described herein are used to provide a further understanding of the present invention, and constitute a part of this application. The schematic embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation to the present invention. In the drawings:

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0026] The following gives specific embodiments.

[0027] Embodiment 1

[0028] Please refer to Figure 1 As shown, an ultra-light composite material structure board, its structure includes a foam aluminum material as the inner layer and an aluminum alloy material as the outer layer.

[0029] The inner layer 1 of the composite material structure board uses foam aluminum, and the density of the foam aluminum is 0.5 g / cm 3 , which has good compressive strength and impact resistance. At the same time, the foam aluminum material has high heat insulation and sound insulation properties. In the outer layer 2, an aluminum alloy material is selected, and its thickness is 0.2 cm, which can effectively improve the durability and corrosion resistance of the structure board. The total thickness of the entire composite material structure board is 5 cm, where the thickness of the inner layer 1 is 4.5 cm and the thickness of the outer layer 2 is 0.5 cm.

[0030] For the composite material structure board of this embodiment, using foam aluminum as the material of the inner layer 1, its light weight characteristic greatly reduces the weight of the board. The use of the aluminum alloy outer layer 2 makes the board have significant advantages in terms of corrosion resistance and weather resistance.

[0031] The strength and stiffness of the structural board meet the requirements of the building structure usage standards, and it can withstand large loads and external impacts. Moreover, the composite material structural board has good heat insulation and sound insulation effects, which can effectively reduce the temperature difference between indoors and outdoors and reduce the transmission of external noise.

[0032] Example 2

[0033] Please refer to Figure 1 As shown, a super-lightweight composite material structural board, its inner layer 1 is made of polystyrene foam material, and the outer layer 2 uses stainless steel material.

[0034] The inner layer 1 selects polystyrene foam material (XPS foam), and its density is 0.03 g / cm 3 , which has good heat preservation, sound insulation and compressive capacity. The outer layer 2 is made of stainless steel material with a thickness of 0.3 cm. The stainless steel material can provide additional corrosion resistance and strength for the composite board. The total thickness of the composite material structural board is 6 cm, the thickness of the inner layer 1 is 5.5 cm, and the thickness of the outer layer 2 is 0.5 cm.

[0035] The composite material structural board adopts a molding process to combine the polystyrene foam with the stainless steel outer layer 2 material. During the production process, the polystyrene foam is injected into the mold to form a uniform foam layer, and then the stainless steel film is firmly covered on the surface of the foam layer by hot pressing method, and finally a structural board with excellent physical properties and chemical stability is formed.

[0036] In addition to the characteristics of being super-light, durable and environmentally friendly, the composite material structural board of this example also has strong compressive and impact resistance capabilities, and can meet the long-term usage requirements of building structures. At the same time, the polystyrene foam layer can effectively reduce the thermal conductivity of the board and improve the energy-saving effect of the building.

[0037] To further improve the application of the composite material structural board of the present invention, the following provides an extended description of the examples:

[0038] Expansion of Example 1:

[0039] Based on Example 1, a multi-layer composite structural board design can also be adopted. Between the foam aluminum inner layer 1 and the aluminum alloy outer layer 2, a second layer of material, such as a carbon fiber reinforced plastic (CFRP) layer, can be added. This carbon fiber layer can provide higher tensile strength and impact resistance performance, and at the same time further reduce the weight of the board.

[0040] The inner layer 1 of the aluminum foam has a thickness of 3.5 cm, the carbon fiber layer has a thickness of 0.3 cm, and the aluminum alloy outer layer 2 has a thickness of 0.2 cm, finally forming a composite structural board with a total thickness of 4 cm. This multi-layer design plays an important role in enhancing the strength and durability of the board, and is particularly suitable for environments that require additional strength and higher corrosion resistance, such as coastal buildings or high-humidity environments.

[0041] Expansion of Example 2:

[0042] The composite structural board of the present invention can also use environmentally friendly materials to replace traditional metal materials.

[0043] In Example 2, the stainless steel outer layer 2 can be replaced with a polymer composite material with good corrosion resistance, such as glass fiber reinforced plastic (GFRP). The thickness of the GFRP outer layer 2 can be 0.4 cm, which has good corrosion resistance, lightweight and impact resistance. At the same time, its manufacturing process is relatively simple and the cost is low.

[0044] The composite structural board using GFRP materials not only ensures strength and durability, but also can effectively reduce the production cost of materials and meet a wider range of construction needs. Through this expanded design, the composite structural board has more options and can better meet the usage requirements under different building types and environmental conditions.

[0045] The following is a detailed data sheet of each material.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
