Description

Technical Field

[0001] This utility model relates to the field of asbestos board technology, and in particular to nano-insulating asbestos board. Background Technology

[0002] Asbestos boards are boards made primarily from asbestos through specific processes. Traditional asbestos boards have been phased out due to health risks. Nanomaterials, while ensuring performance, must completely eliminate harmful substances to guarantee safe use. The development of nanotechnology has brought new opportunities to the field of insulation materials. Nanomaterials possess small size effects, surface effects, and quantum tunneling effects, giving them significant advantages in insulation performance, mechanical strength, and heat resistance. By combining nanomaterials with traditional insulation materials, the overall performance of the materials can be effectively improved, meeting the needs of modern industry for efficient, safe, and environmentally friendly insulation materials.

[0003] To this end, Chinese patent application number CN 209159054U discloses an acid and alkali resistant asbestos-free board, including a pressure-resistant layer. High-temperature resistant layers are connected to the upper and lower sidewalls of the pressure-resistant layer, and acid and alkali resistant layers are connected to the sidewall of the high-temperature resistant layer away from the pressure-resistant layer. This invention, by setting the acid and alkali resistant layer, is made of a mixture of nitrile rubber and fluororubber. Fluororubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of its main chain or side chains. The introduction of fluorine atoms endows the rubber with excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance, and atmospheric aging resistance. It has been widely used in aerospace, aviation, automotive, petroleum, and household appliances, and is an irreplaceable key material in advanced defense industries. Nitrile rubber has excellent oil resistance and also possesses certain corrosion resistance characteristics. By setting the pressure-resistant layer, which is made of pressure-resistant rubber, the asbestos board has good resilience.

[0004] The aforementioned acid and alkali resistant asbestos-free board is difficult to install, leading to installation difficulties and significantly increasing construction time. Inaccurate cutting may result in material waste and require repeated adjustments, while complex splicing may slow down the overall construction progress. The technically demanding installation process requires skilled workers, thus increasing labor costs. If workers lack sufficient skills, operational errors may cause material damage, further increasing costs. Improper cutting or operational errors during installation may also lead to material waste and additional procurement costs. Utility Model Content

[0005] The purpose of this invention is to provide a nano-insulating asbestos board to solve the defects of existing nano-insulating asbestos board materials.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a nano-insulating asbestos board, comprising a first board body; A second plate is installed at one end of the first plate, and a protective layer is provided on the outer walls of both sides of the first and second plates. The outer sides of both ends of the first plate and the second plate are provided with positioning structures. The positioning structures include positioning blocks provided on the outer sides of both ends of the first plate and the second plate, and positioning holes are provided inside the positioning blocks. A screw is installed inside the positioning hole, and a nut is threaded to one end of the screw. A locking structure is provided inside the first plate near the second plate.

[0007] Furthermore, a screw on one side of the positioning block penetrates the first plate, and a screw on the other side of the positioning block penetrates the second plate, which facilitates the positioning of the first and second plates.

[0008] Furthermore, the positioning block is fixedly connected to the first plate and the second plate by screws to prevent displacement.

[0009] Furthermore, the protective layer includes an epoxy resin adhesive disposed on both sides of the first plate and the second plate, an asbestos cement board disposed on the outside of the epoxy resin adhesive, and nano-magnesium oxide disposed on the outside of the asbestos cement board, which provides protection to the outer sides of the first plate and the second plate.

[0010] Furthermore, the epoxy resin adhesive is an adhesive layer, the asbestos cement board is a heat insulation layer, and the nano-magnesium oxide is an insulating layer; the adhesive layer also provides protection.

[0011] Furthermore, the engaging structure includes a first slot formed inside the first plate near one end of the second plate, an engaging block being provided inside the first slot, and a second slot being formed inside the second plate at one end of the first slot, so that the engaging block can engage with the first plate and the second plate.

[0012] Furthermore, one end of the locking block extends into the second slot, and the locking block engages with the first plate and the second plate respectively through the first locking slot and the second slot, facilitating disassembly and installation.

[0013] The advantages of the nano-insulating asbestos board provided by this utility model are: by setting the nano-insulating asbestos board, the asbestos board can be nano-insulated, making its effect better, and the snap-fit ​​structure makes its effect even better when nano-insulating the asbestos board. By setting up a snap-fit ​​structure, when nano-insulating asbestos boards, because there are first slots on both sides of one end of the first board and second slots on both sides of one end of the second board, the snap-fit ​​block extends into the second slot and snaps into the first and second slots to form a snap-fit ​​structure, which makes the snap-fit ​​block easy to disassemble and replace, reducing maintenance time and costs and improving work efficiency. By incorporating a protective layer, the asbestos board is nano-insulated using an epoxy resin adhesive as the bonding layer. Epoxy resin adhesive has excellent bonding properties, enabling it to firmly bond the various layers of the asbestos board or combine with other materials, significantly improving the overall structural strength. The insulation layer is made of asbestos cement board, which has a low thermal conductivity and good heat insulation performance. It also has high product density and good sound insulation. The insulation layer is made of nano-magnesium oxide, which has excellent insulation properties. Attached Figure Description
