Description

Technical Field

[0001] This utility model relates to the field of composite board technology, specifically a composite board with good thermal insulation effect. Background Technology

[0002] Composite panels are sheet-like materials made by combining two or more different materials through physical or chemical methods. These materials are typically made by bonding, pressing, or other techniques to combine raw materials with different properties in order to improve their physical, chemical, and processing properties.

[0003] Existing composite panels use relatively limited materials, primarily organic foam as the main insulation material. This results in ineffective insulation. Furthermore, gaps often remain between the panels after installation. These gaps not only affect the aesthetics of the material but also severely compromise the overall insulation performance. Heat easily escapes through these gaps, creating thermal bridges and preventing effective insulation of indoor and outdoor temperatures, further increasing energy consumption and reducing comfort.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-5 As shown in this embodiment, a composite board with good thermal insulation effect includes a fixed frame 1, a support plate 8 fixedly connected between the inner walls of the fixed frame 1, a metal frame 4 fixedly connected to the top of the support plate 8 and between the inner walls of the fixed frame 1, hollow sound insulation cotton 5 fixedly connected inside the metal frame 4, a sound insulation felt 9 fixedly connected between the hollow sound insulation cotton 5 and the top of the metal frame 4, a composite board structure is provided above the sound insulation felt 9 and between the inner walls of the fixed frame 1, and a splicing structure is provided on the outside of the fixed frame 1. The composite board structure includes a polyurethane foam board 10 and a glass wool composite board 1. 1. The vacuum insulation panel 12 and the aluminum foil composite material 13, the sound insulation felt 9, the polyurethane foam board 10, the glass wool composite board 11 and the vacuum insulation panel 12 are all bonded together with epoxy resin adhesive. The vacuum insulation panel 12 and the aluminum foil composite material 13 are provided with an interlocking structure. The interlocking structure includes embedded nails 15. The embedded nails 15 are fixedly connected at equal intervals to the bottom of the aluminum foil composite material 13. The top of the vacuum insulation panel 12 is provided with an embedded groove 16. One end of the embedded nail 15 extends into the interior of the embedded groove 16. A surface layer 14 is provided on the outer side of the aluminum foil composite material 13 and between the inner wall of the fixing frame 1.

[0023] Before using composite panels, they should be spliced ​​and installed according to actual needs. During the splicing and installation process, the splicing structure can effectively reduce or avoid gaps between the panels. After splicing, the connection between the panels can be strengthened by the external joint sealant, making the spliced ​​composite panels more stable.

[0024] When using composite panels, the composite panel structure, composed of polyurethane foam board 10, glass wool composite board 11, vacuum insulation board 12, and aluminum foil composite material 13, effectively improves the thermal insulation effect of the composite panel. Polyurethane foam board 10, as one of the core components of this composite material, has excellent low thermal conductivity and low density, reducing the overall weight of the material while maintaining good thermal insulation. Glass wool composite board 11 provides additional thermal and sound insulation properties. The fiber structure of glass wool not only effectively blocks heat conduction but also absorbs sound waves, thereby improving the overall comfort and practicality of the material. Furthermore, the fire-resistant properties of glass wool increase the safety of the composite panel. Vacuum insulation board 12, as a high-end insulation solution, has an extremely low thermal conductivity, providing excellent thermal insulation with minimal thickness. The application of aluminum foil composite material 13 effectively enhances the composite panel's moisture resistance, fire resistance, and heat reflection capabilities. Aluminum foil not only blocks moisture penetration but also helps reflect heat back into the room, further improving the thermal insulation effect.

[0025] The combination of hollow sound insulation cotton 5 and sound insulation felt 9 in the composite board structure can play a role in blocking and silencing sound, thus improving the sound insulation effect of the composite board during use.

[0026] like Figures 1-5 As shown, the splicing structure includes two connectors 2 and two connecting plates 3. The two connectors 2 and two connecting plates 3 are respectively fixedly connected to the outside of the fixed frame 1. The top of the connector 2 is provided with a positioning hole 6. The inside of the positioning hole 6 is threaded with a connecting bolt 7. One end of the connecting bolt 7 extends into the inside of the connecting plate 3. A surface layer 14 is provided on the outside of the aluminum foil composite material 13 and between the inner wall of the fixed frame 1.

[0027] During the splicing and installation, the positioning hole 6 on the connector 2 is aligned with the hole on the connecting plate 3 so that the bottom of the connector 2 contacts the top of the connecting plate 3. After the splicing is completed, the connection is fixed by the connecting bolt 7, thereby improving the tightness and stability between the composite panels.

[0028] This utility model provides a composite board with good thermal insulation effect. The specific working principle is as follows: Before using the composite board, it is first spliced ​​and installed according to the actual use requirements. During the splicing and installation process, the positioning hole 6 on the connector 2 is aligned with the hole on the connecting plate 3, so that the bottom of the connector 2 contacts the top of the connecting plate 3. After the splicing is completed, it is fixedly connected by connecting bolts 7, thereby effectively reducing or avoiding gaps between the boards. At the same time, after the splicing is completed, the connection between the boards can be strengthened by the external joint filler strip.

[0029] During use, the composite board structure composed of polyurethane foam board 10, glass wool composite board 11, vacuum insulation board 12 and aluminum foil composite material 13 can effectively improve the thermal insulation effect of the composite board. At the same time, the combination of hollow sound insulation cotton 5 and sound insulation felt 9 in the composite board structure can play a role in sound insulation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
