[0002] Light steel prefabricated houses require the use of panels during construction.

[0003] According to application number CN202120027541.9, a prefabricated light steel building decorative panel is disclosed, which particularly relates to the field of decorative panel technology, including a panel body; the top left and right sides of the panel body are respectively provided with perforations and upper sliding grooves, and a thin block is fixedly connected to the top right side of the inner wall of the upper sliding groove, and a round hole is passed through the middle of the thin block.

[0004] The panels in the above cases do not have thermal insulation properties, which can easily lead to heat loss from the room. They also lack moisture resistance, which can severely affect their lifespan if the panels become damp. In addition, the sound insulation performance of the panels is not ideal, which can easily cause noise to spread through the panels and reduce their practicality. Therefore, we provide a light steel prefabricated house panel with thermal insulation and moisture resistance functions. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A type of light steel prefabricated house panel with thermal insulation, heat insulation, and moisture-proof functions includes a panel body 1. The panel body 1 is composed of a base layer 101, a sound insulation layer 102, a first thermal insulation layer 103, a first moisture-proof layer 104, a first protective outer layer 105, a reinforcing layer 106, a second thermal insulation layer 107, a second moisture-proof layer 108, and a second protective outer layer 109. The sound insulation layer 102 is placed on top of the base layer 101, which is made of light steel keel substrate and has a thickness of 8-12mm. The first thermal insulation layer 103 is placed on top of the sound insulation layer 102, which is made of butyl rubber sound insulation felt and has a thickness of 3-5mm. The first moisture-proof layer 104 is placed on top of the first thermal insulation layer 103, the first protective outer layer 105 is placed on top of the first moisture-proof layer 104, and the reinforcing layer 106 is placed on top of the base layer. At the bottom of 101, the reinforcing layer 106 is made of cold-formed thin-walled steel with a wall thickness of 0.8-1.5mm. The second thermal insulation layer 107 is set at the bottom of the reinforcing layer 106. The first thermal insulation layer 103 and the second thermal insulation layer 107 are both made of urethane foam with a thickness of 30-50mm. The second moisture-proof layer 108 is set at the bottom of the second thermal insulation layer 107. The first moisture-proof layer 104 and the second moisture-proof layer 108 are both made of polyvinyl alcohol film with a thickness of 0.1-0.2mm. The second protective outer layer 109 is set at the bottom of the second moisture-proof layer 108. The first protective outer layer 105 and the second protective outer layer 109 are both made of aluminum-zinc coated color steel plate. The surface of the aluminum-zinc coated color steel plate is coated with a nano-silica moisture-proof coating with a thickness of 50-100μm. The nano-silica moisture-proof coating also has a heat insulation effect.

[0021] The top of the light steel keel substrate is bonded with butyl rubber sound insulation felt using neoprene adhesive to form a sound insulation layer 102. The bottom of the light steel keel substrate is welded with cold-formed thin-walled steel to form a reinforcing layer 106. The top of the butyl rubber sound insulation felt and the bottom of the cold-formed thin-walled steel are both sprayed with urethane foam to form a first thermal insulation layer 103 and a second thermal insulation layer 107. The top of the first thermal insulation layer 103 and the bottom of the second thermal insulation layer 107 are both hot-pressed with polyvinyl alcohol film to make the film tightly bonded to the foam layer, forming a first moisture-proof layer 104 and a second moisture-proof layer 108. The top of the first moisture-proof layer 104 and the bottom of the second moisture-proof layer 108 are both bonded with aluminum-zinc coated steel plates using epoxy resin structural adhesive. After the multi-layer structure is processed by a hot press, it is ensured that each layer is firmly bonded and there is no delamination or peeling, forming the board body 1.

[0022] The board body 1 is provided with a splicing component 2, which includes a plug 21 and a slot 22. There are two plugs 21, which are respectively installed on the front and left side of the board body 1. There are two slots 22, which are respectively opened on the right side and the rear side of the bottom of the board body 1. A limit block 23 is installed on the top of the plug 21, and a limit groove 24 adapted to the limit block 23 is opened on the bottom of the slot 22. By setting up the splicing component 2, it is convenient to splice and install two adjacent boards. The splicing joint of the two boards is coated with a waterproof sealant. By applying the waterproof sealant to the splicing joint, combined with the physical seal of the limit block 23 and the limit groove 24, a double waterproof structure of mechanical locking and adhesive strip sealing is formed.

[0023] By setting a sound insulation layer 102, the sound insulation effect of the board is improved. Through the damping and vibration reduction principle, the transmission of airborne and solid-borne sound is reduced, meeting the sound insulation standards for the partition walls of residential buildings and effectively blocking outdoor noise and indoor noise. By setting a first thermal insulation layer 103 and a second thermal insulation layer 107, the thermal insulation effect of the board is improved, forming a double-sided thermal barrier to prevent the loss of indoor heat. By setting a first moisture-proof layer 104 and a second moisture-proof layer 108, the moisture-proof effect of the board is improved, preventing external moisture penetration. The nano-silica moisture-proof coating on the surface of the aluminum-zinc coated steel plate forms a hydrophobic layer, which can block surface moisture penetration and further improve the moisture-proof performance. By setting a first protective outer layer 105, a second protective outer layer 109 and a reinforcing layer 106, the strength of the board is improved and the service life of the board is extended.

[0024] In use, apply sealing and waterproof adhesive to the splicing component 2 of the board body 1. The board body 1 drives the slot 22 and the limiting groove 24 to move from top to bottom, so that the insert block 21 on the other board body 1 is inserted into the slot 22 and the limiting block 23 is inserted into the limiting groove 24. At the same time, ensure that the adjacent sealing and waterproof adhesives are bonded together, and the splicing of two adjacent boards can be completed.
