Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of building insulation materials, specifically relating to an environmentally friendly heat-insulating aluminum foil foam composite board. Background Technology
[0002] In the construction industry, with increasingly stringent energy-saving standards, the performance requirements for thermal insulation materials are becoming more and more demanding. Existing building insulation materials (such as traditional foam boards and rock wool boards) generally have certain shortcomings:
[0003] Limited thermal insulation efficiency: Thermal insulation structures made of a single material are difficult to block both heat conduction and heat radiation at the same time. In high or low temperature environments, heat loss or intrusion is likely to occur, resulting in high building energy consumption.
[0004] Installation and transportation are inconvenient: Traditional boards are often spliced using bolts, adhesives and other auxiliary tools, which results in low installation efficiency and thermal bridges at the joints; when stacked for transportation, they lack a fixed structure and are prone to sliding and misalignment, leading to wasted transportation space and increased loss rate. Utility Model Content
[0005] The purpose of this utility model is to provide an environmentally friendly heat-insulating aluminum foil foam composite board to solve the problems of limited heat insulation efficiency and inconvenient installation and transportation mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly heat-insulating aluminum foil foam composite board, comprising a composite board body and connecting protrusions disposed around the composite board body. The composite board body is composed of a foam board and an aluminum foil layer. The aluminum foil layer is fixed to the outside of the foam board. Magnetic blocks are fixed at the four corners of the surface of the composite board body. Grooves are provided at the four corners of the bottom of the composite board body, and adsorption sleeves that adsorb to the magnetic blocks are fixed in the grooves.
[0007] In a further embodiment, multiple connecting protrusions on one side of the composite plate body are staggered with multiple connecting protrusions on the other side, and the shape of the gap between two connecting protrusions matches the contour of a single connecting protrusion.
[0008] In a further embodiment, the surface of the aluminum foil layer is coated with a fire-retardant coating.
[0009] In a further embodiment, an environmentally friendly flame retardant is added to the foam board.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] This environmentally friendly heat-insulating aluminum foil foam composite board is composed of a foam board and an aluminum foil layer. The closed pores inside the foam board form a heat-insulating cavity, effectively blocking heat conduction. The aluminum foil layer reduces heat intrusion by reflecting heat radiation. The two work together to achieve dual heat insulation of "blocking + reflection", which effectively improves the heat insulation efficiency. At the same time, the dense structure of the aluminum foil layer can block water vapor penetration, and has excellent moisture-proof performance, making it suitable for humid environments.
[0012] The lightweight foam board material reduces the overall weight of the composite board, making it easy to handle and install. The aluminum foil layer wrapping the foam board forms a rigid structure, improving the board's bending strength and preventing deformation damage during transportation and installation.
[0013] The connecting protrusions around the main body of the composite board are designed with staggered distribution. The shape of the connecting protrusions matches the gaps, allowing for direct snap-fit splicing. Installation can be completed without tools, effectively improving installation efficiency and ensuring tight joints, thus reducing thermal bridging effects.
[0014] The magnetic blocks and adsorption sleeves at the four corners of the composite board can attract each other and be fixed by magnetic force when stacked, preventing the boards from sliding and misaligning, reducing the space occupied during transportation, and providing high stacking stability. It can be stacked in multiple layers, reducing transportation costs and loss rates. This environmentally friendly heat-insulating aluminum foil foam composite board has the advantages of high-efficiency heat insulation, moisture resistance, lightweight, and convenient installation. It has broad application prospects and high practical value, and is easy to stack, making it more convenient for transportation. Attached Figure Description

[0020] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0021] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0022] This utility model provides, for example Figure 1-3 The environmentally friendly heat-insulating aluminum foil foam composite board shown includes a composite board body 1 and connecting protrusions 5 disposed around the composite board body 1. The composite board body 1 is composed of a foam board 2 and an aluminum foil layer 3. The foam board 2 (such as EPS or XPS foam) has a large number of closed pores inside. Environmentally friendly flame retardants are added to the foam board 2. The fire resistance is improved by adding environmentally friendly flame retardants (such as phosphorus-based and nitrogen-based flame retardants). The aluminum foil layer 3 is fixed to the outside of the foam board 2 by adhesive or hot pressing process. Its surface is coated with a fireproof coating 4 (such as intumescent fireproof coating), forming a double heat insulation structure of "foam board heat insulation + aluminum foil layer reflection".
[0023] Multiple connecting protrusions 5 on one side of the composite board body 1 are staggered with multiple connecting protrusions 5 on the other side. The shape of the gap between two connecting protrusions 5 matches the outline of a single connecting protrusion 5. The connecting protrusions 5 and the gap shape match, so they can be directly snapped together. Installation can be completed without tools, which effectively improves the installation efficiency and makes the joints tight, reducing the thermal bridge effect.
[0024] Magnetic blocks 6 are fixed at the four corners of the surface of the composite board body 1. Grooves are opened at the four corners of the bottom of the composite board body 1, and adsorption sleeves 7 that attract each other with the magnetic blocks 6 are fixed in the grooves. The adsorption sleeves 7 are made of metal (such as iron or nickel). The magnetic blocks 6 and adsorption sleeves 7 at the four corners of the composite board body 1 can attract each other. When stacked, they are fixed by magnetic force to prevent the boards from sliding and misaligning, reduce the space occupied during transportation, and have high stacking stability. They can be stacked in multiple layers to reduce transportation costs and loss rate.

[0027] Working principle:
[0028] This environmentally friendly heat-insulating aluminum foil foam composite board transports multiple composite board bodies 1 to a designated location. During transportation, the multiple composite board bodies 1 are attached to each other, and the magnetic blocks 6 at the four corners of the composite board body 1 are attracted to the adsorption sleeves 7. When stacked, they are fixed by magnetic force to prevent the boards from sliding and misaligning, thus reducing the space occupied during transportation.
[0029] After the composite board body 1 is transported to the designated location, multiple composite board bodies 1 are laid flat in the designated location. The connecting protrusion 5 on one composite board body 1 is engaged in the gap of another composite board body 1 to complete the splicing and fixing of two composite board bodies 1. This process is repeated to complete the splicing of multiple composite board bodies 1. After splicing, the closed air pores of the foam board 2 form a heat insulation cavity, blocking the heat conduction caused by air convection. The aluminum foil layer 3, with its metal reflective properties, reflects external heat radiation. The combination of the two achieves "blocking + reflection" dual heat insulation. At the same time, the dense structure of the aluminum foil layer 3 effectively blocks water vapor penetration, ensuring the stability of the board in a humid environment.
[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.
