Description

Technical Field

[0001] This utility model relates to the field of rock wool board edge sealing technology, specifically a PU four-sided edge-sealed rock wool board. Background Technology

[0002] Rock wool board is a commonly used building insulation material, usually composed of rock wool core and metal panel, used for heat insulation, fireproofing and sound insulation of walls, roofs and other structures.

[0003] Rock wool boards typically require PU edge sealing during production. Current edge sealing methods only seal the long sides (left and right sides) of the board to prevent water absorption and enhance strength. However, the top and bottom (short sides) are usually exposed. Relying solely on construction sealant still results in issues such as insufficient waterproofing, stain resistance, and structural strength. Specifically: Regarding waterproof performance: With the short side exposed, the board is prone to absorbing water during transportation or use, which can cause the core material to become damp, reducing insulation and shortening its service life.

[0004] In terms of structural strength: the short sides of the sheet metal lack protection and are easily affected by impacts and compression, which affects its durability.

[0005] Regarding splicing and sealing: the short side is exposed, requiring additional sealing during construction, which is complex and the results are inconsistent.

[0006] Regarding sealing and contamination: Exposed rock wool fibers easily absorb dust or pollutants, and long-term exposure to moisture will accelerate aging.

[0007] This makes it difficult for existing rock wool boards to meet the high standards of modern buildings for thermal insulation, waterproofing, fireproofing, and sealing.

[0008] Based on this, the present invention provides a PU four-sided edge-sealed rock wool board to solve the above problems. Utility Model Content

This utility model has an ingenious structure and focuses on practicality, effectively solving the technical problems that existing rock wool boards cannot meet the requirements of modern buildings for heat preservation, waterproofing and sealing.

[0010] A PU four-sided edge-sealed rock wool board includes a rock wool core material, the four sides of which are wrapped with a PU edge-sealing layer, and the rock wool core material and the PU edge-sealing layer are bonded with connecting outer skins on both the front and back sides.

[0011] Preferably, the thickness of the rock wool core material is 30-150mm.

[0012] Preferably, the thickness of the PU sealing layer is 30-150mm.

[0013] Preferably, the thickness of the connecting outer skin is 0.05-1 mm.

[0014] Preferably, both of the connecting outer skins are metal panels.

[0015] Preferably, of the two connecting skins, one connecting skin is a soft surface layer and the other connecting skin is a metal panel.

[0016] Preferably, both of the connecting outer skins are soft outer layers.

[0017] To achieve the above objectives, the present invention adopts the following technical solution: This utility model achieves the following technical effects by combining rock wool core material with a waterproof interlayer and connecting outer skin on both the front and back sides: All-around waterproofing: Four-sided edge sealing prevents water absorption from short sides, improving the waterproof performance of the board; Enhanced structural strength: Sealing the top and bottom edges increases structural strength and reduces damage during transportation and construction; Excellent sealing effect: Good sealing performance after construction, reducing air and water leakage problems; Anti-pollution and anti-aging: Protects exposed rock wool fibers and delays aging.

[0023] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 2 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0024] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] This utility model is a PU four-sided edge-sealed rock wool board, including a rock wool core material 3, which is high-density rock wool and provides heat insulation, fireproofing and sound insulation functions. The four sides of the rock wool core material 3 are wrapped with a PU edge-sealing layer 1, which is made of polyurethane. The PU edge-sealing layer 1 can effectively prevent water absorption on the short side, improve the waterproof performance of the board, increase the structural strength, reduce damage during transportation and construction, prevent pollution, prevent aging and protect the exposed rock wool fibers. The rock wool core material 3 and the PU edge-sealing layer 1 are bonded with connecting outer skin 2 on the front and back sides.

[0026] The thickness of rock wool core material 3 is 30-150mm.

[0027] The thickness of the PU edge sealing layer 1 is 30-150mm.

[0028] The thickness of the outer skin 2 is 0.05-1.2mm.

[0029] Both connecting outer sheaths 2 are metal panels.

[0030] Of the two connecting skins 2, one connecting skin 2 is a soft surface layer, and the other connecting skin 2 is a metal panel.

[0031] Both connecting outer skins 2 are soft surface layers.

[0032] The metal panel or soft surface layer is bonded to the surface of the rock wool core material 3 by hot pressing or adhesive bonding.

[0033] The PU edge sealing layer 1 is formed in one step by the equipment to cover the edge and is tightly bonded to the metal panel or soft surface layer and the rock wool core material 3.

[0034] In this embodiment, rock wool raw materials are compositely compressed into a single piece to form rock wool core material 3. Then, rock wool core material 3 is cut into the required size and cured by equipment. Rock wool core material 3 is placed in the equipment and sealed with PU sealing layer 1. After sealing, PU material is injected and the equipment is used to cover the top, bottom, left and right sides. Production can be carried out intermittently or continuously. After PU curing, a complete encapsulation structure is formed, thus forming a sealing with PU sealing layer 1. After sealing, the connecting outer skin 2 is bonded and compressed to both sides of rock wool core material 3. When the structure is being transported, the rock wool core material 3 with PU edge sealing layer 1 on all four sides can effectively prevent water absorption on the short side, improve the waterproof performance of the board, increase the structural strength, reduce damage during transportation and construction, prevent pollution and aging, protect the exposed rock wool fibers, reduce air leakage and water leakage problems, and extend the service life. When the structure is actually used, the rock wool core material 3 itself and the connecting outer skin 2 on the surface can achieve the effects of heat insulation, fireproofing, sound insulation and waterproofing.

[0035] This invention achieves all-round waterproofing, pollution prevention, enhanced structural strength, and improved splicing sealing effect by sealing the four sides (top, bottom, left, and right) with PU. It also improves construction efficiency and service life.

[0036] Working principle: Rock wool raw materials are composite and compacted to form rock wool core material 3. After the rock wool core material 3 is cut to the required size, it is placed in the equipment, PU material is injected, and the equipment is used to cover its top, bottom, left and right sides. After the PU is cured, the edge sealing is completed. On the front and back sides of the rock wool core material 3 and the PU edge sealing layer 1, the connecting skin 2 is glued (the connecting skin 2 can be a metal panel, a soft layer, or one side of metal panel and one side of soft layer). The rock wool core material 3 itself and the connecting skin 2 achieve heat insulation, fireproofing, sound insulation and waterproofing effects. The PU edge sealing layer 1 prevents water absorption on the short side and improves waterproof performance and mechanical strength.

[0037] This utility model, through the composite of rock wool core material 3 and the connecting outer skin 2 on the front and rear sides, can achieve the following technical effects: All-around waterproofing: Four-sided edge sealing prevents water absorption from short sides, improving the waterproof performance of the board; Enhanced structural strength: Sealing the top and bottom edges increases structural strength and reduces damage during transportation and construction; Excellent sealing effect: Good sealing performance after construction, reducing air and water leakage problems; Anti-pollution and anti-aging: Protects exposed rock wool fibers and delays aging.

[0038] Simple construction and cost-saving: The equipment is formed in one step, eliminating the need for secondary edge sealing on site.

[0039] Highly adaptable: The edge banding thickness and board size can be adjusted according to requirements, making it suitable for a wide range of applications.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
