Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a polyurethane foam insulation board. Background Technology

[0002] In the field of building insulation materials, traditional polyurethane foam insulation boards generally suffer from uneven insulation performance when filled with foaming agent. Most insulation boards simply inject foaming agent through simple holes, lacking reasonable planning and partitioning of the foaming space. This results in irregular diffusion of the foaming agent inside the insulation board, making it difficult to achieve uniform filling. In some areas, the foaming agent accumulates excessively, causing material waste and increasing the weight of the insulation board; while other areas are underfilled, forming weak points in insulation and seriously affecting the overall insulation performance. At the same time, due to the lack of an effective supporting structure during the foaming process, the insulation board is prone to deformation, further reducing the insulation effect. This uneven insulation performance not only fails to meet the high standards of building energy conservation but also increases building energy consumption and subsequent maintenance costs. Innovative technologies are needed to solve this problem. To address these issues, we have proposed a polyurethane foam insulation board. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a polyurethane foam insulation board, which solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a polyurethane foam insulation board, comprising an insulation board;

[0005] A slot is fixedly installed on one side of the insulation board, and a slot is fixedly installed on the side of the insulation board away from the slot. The slot and the slot are dovetail grooves with equal gaps, and the slot and the slot can be engaged with each other.

[0006] The insulation board has multiple sets of injection ports on one side, and all sets of injection ports extend into the interior of the insulation board and are connected together.

[0007] The insulation board has an internal frame, and the surface of the frame has a transition reinforcement layer. The surface of the transition reinforcement layer has a moisture-proof layer, and the side of the moisture-proof layer away from the transition reinforcement layer has a fireproof layer.

[0008] A partition is fixedly installed at the bottom of the slot, and a partition is fixedly installed at the top of the slot.

[0009] Both the slot and the card slot have the same number of mounting holes in the middle.

[0010] The injection port is conical and extends through the interior of the insulation board and is connected to it.

[0011] The frame is arranged in a grid pattern inside the insulation board, and the frame is made of PVC foam board.

[0012] Furthermore, the number of multiple injection ports is equal to the number of grid-shaped meshes.

[0013] A set of stress-dispersing nets is fixedly installed at both the top and bottom of the frame. The stress-dispersing nets are made of glass fiber and are formed by cross-laying of warp and weft yarns to form a diamond-shaped grid.

[0014] The transition reinforcement layer is made of basalt fiber felt and is fixed to the surface of the frame with epoxy resin adhesive.

[0015] The moisture-proof layer is made of an aluminum foil composite film and a non-woven fabric interlayer bonded together with butyl tape.

[0016] Furthermore, the moisture-proof layer is fixedly connected to the surface of the transition reinforcement layer using epoxy resin adhesive.

[0017] The fireproof layer is made of magnesium oxide board and is fixedly connected to the surface of the moisture-proof layer by high-temperature resistant silicone sealant.

[0018] The surface of the fireproof layer is coated with anti-corrosion paint.

[0019] Compared with the prior art, this utility model provides a polyurethane foam insulation board, which has the following beneficial effects:

[0020] Addressing the issues of loosening and poor sealing in traditional insulation board splicing, this device utilizes a dovetail groove design with slots and grooves, along with partitions and mounting holes, to achieve a tight and stable splicing effect. During installation, the dovetail groove structure ensures a tight interlocking between insulation boards, while the partitions prevent over-clamping, and bolt reinforcement further enhances the connection strength, effectively preventing gaps and significantly improving overall sealing. This reduces heat loss and air infiltration. Compared to traditional splicing methods, it offers significant improvements in both construction efficiency and post-installation stability, making it particularly suitable for insulation installation needs in various complex building structures.

[0021] Addressing the issues of uneven insulation, fragile structure, and insufficient protective performance inherent in traditional insulation boards, this device cleverly combines a conical injection port with a grid-like mesh frame to ensure uniform diffusion and filling of the polyurethane foam, fundamentally solving the problem of uneven insulation. The glass fiber stress-dispersing mesh at the top and bottom of the frame effectively disperses foaming shrinkage stress and external impacts, preventing cracking and damage to the insulation board. A basalt fiber felt transition reinforcement layer enhances the overall structural strength, while an aluminum foil composite film and non-woven fabric moisture-proof layer isolate moisture intrusion. The magnesium oxide board fireproof layer combined with an anti-corrosion paint surface effectively improves fire resistance and corrosion resistance. The synergistic effect of these components gives the insulation board excellent insulation, moisture resistance, fire resistance, and impact resistance, comprehensively meeting the stringent requirements of modern buildings for high-quality insulation materials.

[0028] 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.

[0029] Please see Figure 1-5 A polyurethane foam insulation board, comprising insulation board 1;

[0030] A slot 2 is fixedly installed on one side of the insulation board 1, and a slot 3 is fixedly installed on the side of the insulation board 1 away from the slot 2. The slot 2 and the slot 3 are dovetail grooves with equal gaps, and the slot 2 and the slot 3 can be snapped together.

[0031] Multiple sets of injection ports 9 are provided on one side of the insulation board 1, and all sets of injection ports 9 extend into the interior of the insulation board 1 and are connected together.

[0032] The insulation board 1 has a frame 4 inside, and the surface of the frame 4 has a transition reinforcement layer 6. The surface of the transition reinforcement layer 6 has a moisture-proof layer 7, and the side of the moisture-proof layer 7 away from the transition reinforcement layer 6 has a fireproof layer 8.

[0033] Furthermore, a partition is fixedly installed at the bottom of slot 2, and a partition is fixedly installed at the top of slot 3;

[0034] Both slot 2 and slot 3 have the same number of mounting holes in the middle. During installation, the slot 2 of one insulation board is interlocked with the slot 3 of another insulation board. The dovetail groove design makes the connection tight and stable, and the partition prevents over-interlocking. Bolts can be used to further reinforce the connection through the mounting holes to achieve splicing and installation of insulation boards.

[0035] Furthermore, the injection port 9 is conical and extends through and connects to the interior of the insulation board 1. The conical design facilitates the injection of polyurethane foaming agent, reduces the resistance during foaming agent injection, and allows the foaming agent to flow more smoothly into the interior of the insulation board 1. At the same time, it helps the foaming agent to diffuse evenly inside, improving the overall uniformity of the insulation effect of the insulation board.

[0036] Furthermore, the frame 4 is arranged in a grid pattern inside the insulation board 1. The frame 4 is made of PVC foam board, and its structure can provide molding space for polyurethane foaming agent, ensuring the stability of the internal structure of the insulation board 1 after foaming.

[0037] Furthermore, the number of multiple injection ports 9 is equal to the number of grid lines. The polyurethane foam is injected through the injection ports 9, which fills the inside of the grid lines of the frame 4. The frame 4 plays a supporting and separating role, ensuring that the foam is evenly distributed and forming a stable insulation structure.

[0038] Furthermore, a set of stress dispersion nets 5 are fixedly installed at the top and bottom of the frame 4. The stress dispersion nets 5 are made of glass fiber and are formed by cross-laying of warp and weft yarns to form a diamond grid. When the insulation board 1 is subjected to external force, the stress dispersion nets 5 can evenly disperse the stress when the polyurethane foam is cured and shrinks, and when external forces are applied, thus preventing the insulation board 1 from cracking locally, enhancing its impact and pressure resistance, maintaining structural stability, and extending its service life.

[0039] Furthermore, the transition reinforcement layer 6 is made of basalt fiber felt. The transition reinforcement layer 6 is fixedly connected to the surface of the frame 4 by epoxy resin adhesive. The basalt fiber felt has high strength and good flexibility, which can further enhance the structural strength of the insulation board 1. At the same time, during the polyurethane foaming process, it helps the frame 4 maintain a stable structure, ensuring the foaming effect and the overall performance of the insulation board.

[0040] Furthermore, the moisture-proof layer 7 is made by bonding an aluminum foil composite film and a non-woven fabric interlayer together with butyl tape;

[0041] Furthermore, the moisture-proof layer 7 is fixedly connected to the surface of the transition reinforcement layer 6 by epoxy resin adhesive. The aluminum foil composite film has excellent moisture-proof performance, which can effectively block external moisture from penetrating into the interior of the insulation board 1, protect the polyurethane foam material and other internal structures from moisture damage, and maintain the insulation performance and structural stability of the insulation board; the non-woven fabric increases the flexibility and fit of the moisture-proof layer.

[0042] Furthermore, the fireproof layer 8 is made of magnesium oxide board. The fireproof layer 8 is fixedly connected to the surface of the moisture-proof layer 7 by high-temperature resistant silicone sealant. The magnesium oxide board has good fire resistance and can effectively prevent the spread of fire and improve the fire safety of the insulation board.

[0043] The surface of the fireproof layer 8 is coated with anti-corrosion paint, which can prevent the fireproof layer 8 from being corroded by the external environment, ensure that the fireproof layer plays a stable role in the long term, and improve the overall performance and durability of the insulation board.

[0044] Instructions for use

[0045] When the polyurethane foaming agent is injected through injection port 9, the conical injection port 9 reduces flow resistance and guides the foaming agent to diffuse into the interior of the insulation board 1 along the channel. Since the number of injection ports 9 is equal to the number of grid cells in the frame 4, the foaming agent precisely fills each grid cell, and the frame 4, made of PVC foam board, provides a stable support structure for the foaming process. As the foaming agent expands and cures, the glass fiber stress dispersion mesh 5 disperses shrinkage stress through its diamond-shaped mesh structure, preventing the insulation board 1 from cracking. At the same time, the basalt fiber felt transition reinforcement layer 6 assists the frame 4 in maintaining its shape and ensuring uniform foaming. After curing, the aluminum foil composite film moisture barrier 7 blocks external moisture intrusion, the magnesium oxide board fireproof layer 8 improves flame retardant performance, and the anti-corrosion paint extends the service life of the fireproof layer, ultimately forming a building material with comprehensive properties such as heat insulation, moisture resistance, fire resistance, and impact resistance. Adjacent insulation boards are connected by the dovetail groove structure of slot 2 and slot 3, and the partition is limited and reinforced with bolts, achieving rapid splicing and structural stability.
