[0002] With the rapid development of modern industry, electromagnetic shielding technology is increasingly widely used in fields such as military, electronics, and power. Although traditional color steel single plates can meet the requirements of building envelopes to a certain extent, they have problems such as rusting, high maintenance costs, and short service life, and are difficult to meet the requirements of high-end buildings and shielding rooms. In recent years, metal-faced sandwich composite integrated boards have gradually become the mainstream in the construction industry and are widely used in fields such as industrial factories, electronic factories, power factories, and military factories. The integrated board not only has excellent decorative effects but also can effectively solve many defects of color steel single plates, such as no maintenance for 30 years and a service life of more than 50 years.

[0003] However, with the rapid development of military technology, the upgrading and iteration of ultra-high voltage technology, and the country's requirements for high-quality development, the existing metal-faced sandwich composite integrated boards fail to demonstrate electromagnetic shielding performance, and there are still deficiencies in construction efficiency and environmental protection and energy conservation. Especially in the construction of shielding rooms, how to achieve efficient and high-quality electromagnetic shielding functions while taking into account requirements such as green environmental protection and energy efficiency has become a major challenge faced by the industry. Through novelty search, search, and in-depth exploration using large models, the conclusion given by big data is that no innovative composite integrated board that defines future shielding rooms has been found yet.

[0004] Therefore, we provide a high-end metal-faced sandwich composite integrated board for a shielding room to solve the above problems. Summary of the Invention

At the same time, it absorbs all the excellent features, highlights and functions of the integrated boards and other composite boards on the market, and also absorbs the advantageous features and the experience of successful cases of the integrated building shielding and enclosure corrugated boards. The new integrated board one and the new integrated board two are the same in shape and size. The new integrated board one is composed of an enclosure layer 2, a sandwich layer 3 and a shielding layer 1, and the new integrated board two is composed of a shielding layer 1, a sandwich layer 3 and a decorative sound absorption layer 2.

[0025] Embodiment 2

[0026] Please refer to Figure 1 - Figure 2 , on the basis of Embodiment 1, the enclosure layer 2 is made of color-coated steel plate, the base material is galvanized steel plate, aluminum-zinc alloy coated steel plate and aluminum plate, and the surface is color-coated. According to the design requirements, the color-coated steel plate has a variety of colors to choose from. For the decorative sound absorption layer, sound absorption holes are punched on the color-coated steel plate to increase the sound absorption and noise reduction function. The shielding layer 1 is made of galvanized steel plate and aluminum-zinc alloy coated steel plate, and the thickness of the galvanized layer is greater than 100g on both sides. The sandwich layer 3 is made of rock wool, hydrophobic rock wool, glass fiber cotton and polyurethane. The new integrated board one and the new integrated board two are both automatically produced by a special machine on a fully automatic forming and composite production line. The new integrated board one composed of the enclosure layer 2, the sandwich layer 3 and the shielding layer 1 and the new integrated board two composed of the shielding layer 1, the sandwich layer 3 and the decorative sound absorption layer 2 adopt a special duckbill design at the bottom, making the shielding connection simpler and more capable of preventing welding deformation, realizing the electromagnetic shielding function, realizing thermal expansion and contraction compensation, and realizing a new mode and new process of on-site automatic production, large-area assembly welding and hoisting construction. One side of both of them adopts a male-female tapered tongue-and-groove design to ensure no gap at the connection, close fit, no opening, effectively improving the water and air sealing performance of the enclosure layer 2, enhancing the waterproof and moisture-proof functions. The new integrated board one composed of the enclosure layer 2, the sandwich layer 3 and the shielding layer 1 and the new integrated board two composed of the shielding layer 1, the sandwich layer 3 and the decorative sound absorption layer 2 implement sound and heat break design to ensure sound insulation, noise reduction, heat insulation and moisture preservation. Their board surfaces all adopt a wavy design, which is beneficial to the improvement of the building enclosure function and the improvement of the shielding efficiency and sound insulation effect.

[0027] The working principle of the present invention is as follows: The new integrated board one is composed of an enclosure layer 2, a sandwich layer 3 and a shielding layer 1. The enclosure layer 2 is made of color-coated steel plate, the base material is galvanized steel plate, aluminum-zinc alloy coated steel plate or aluminum plate, and the surface is color-coated, with a variety of color options. The sandwich layer 3 is made of materials such as rock wool, hydrophobic rock wool, glass fiber cotton or polyurethane, and has good heat insulation and sound insulation performance. The shielding layer 1 is made of galvanized steel plate or aluminum-zinc alloy coated steel plate to ensure excellent electromagnetic shielding effect.

[0028] The shielding layers 1 of the new integrated board one and the new integrated board two effectively block the penetration of electromagnetic waves through the electrical conductivity of galvanized steel sheets or aluminized zinc steel sheets, achieving electromagnetic shielding functions in a wide frequency band. Its shielding effectiveness meets and exceeds the Class C standard of the national military standard GJB5792A-2021 and is applicable to the frequency band of 10KHz - 50GHz.

[0029] The new integrated board one and the new integrated board two adopt a sound and heat bridge-breaking design to ensure sound insulation, noise reduction, heat insulation, and moisture retention effects. Materials such as rock wool and fiberglass wool in the sandwich layer 3 have good sound insulation and heat insulation properties, which can effectively reduce noise and heat transfer.

[0030] The special duckbill (hook-shaped) design of the new integrated board one and the new integrated board two makes the shielding connection more convenient, prevents welding deformation, and while achieving the electromagnetic shielding function, can also compensate for thermal expansion and contraction, meeting the requirements of on-site automated production and large-area assembly welding.

[0031] The male-female conical tongue-and-groove design of the new integrated board one and the new integrated board two ensures no gaps at the joints, fits tightly, improves the water sealing and air sealing performance of the enclosure layer 2, and enhances the waterproof and moisture-proof functions.

[0032] The wavy board surface design of the new integrated board one and the new integrated board two not only improves the building enclosure function but also enhances the shielding effectiveness and sound insulation effect, further improving the overall performance.

[0033] In this way, an efficient electromagnetic shielding function is achieved, and it also has multiple functions such as sound insulation, heat insulation, and moisture retention, meeting the high standards of future shielding rooms and promoting the technological progress and high-quality development of the shielding industry.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
