Description

Technical Field

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

[0002] Decorative panels are a general term for all panels used for interior and exterior decoration. They come in a wide variety of types and have a broader range of applications. People are also paying more and more attention to the performance of these panels.

[0003] However, when existing decorative panels are used on roofs, in order to ensure their waterproof effect, they are usually coated with a single waterproof coating, which results in poor structural integrity. When subjected to external pressure, they are prone to breakage and damage, and have a short service life. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-3The present invention provides a composite waterproof board, comprising a top plate 1 and a bottom plate 2. The upper surface of the top plate 1 is provided with a waterproof layer 8, and the waterproof layer 8 is provided with a protective layer 9, a waterproof base layer 10 and an adhesive layer from top to bottom.

[0024] The top plate 1 is bonded to the upper end of the bottom plate 2, and a plurality of reinforcing rods 3 are provided between the top plate 1 and the bottom plate 2. The top plate 1 has a plurality of second grooves 5 inside, and the bottom plate 2 has a plurality of first grooves 4 corresponding to the second grooves 5 inside. The reinforcing rods 3 are fixed inside the first grooves 4 and the second grooves 5.

[0025] In this embodiment, the protective layer 9 is a polymer waterproof membrane layer, the waterproof base layer 10 is a high-strength polyester fiber nonwoven fabric, the adhesive layer is a self-adhesive modified bitumen layer, the polymer waterproof membrane layer is made of polymer materials such as ethylene propylene diene monomer (EPDM) rubber or polyvinyl chloride (PVC), and the self-adhesive modified bitumen layer is made of high-quality bitumen with added special modifiers (such as SBS thermoplastic elastomer), and mixed with tackifiers, fillers, etc. to make a self-adhesive modified bitumen adhesive.

[0026] Both the top plate 1 and the bottom plate 2 are made of color steel plate, and the reinforcing rods 3 are made of aluminum alloy. The multiple reinforcing rods 3 are the same size.

[0027] Color steel plates are selected as the material for the top plate 1 and the bottom plate 2. They are cut according to the design dimensions. Color steel plates have certain strength and are easy to process, and can provide basic structural support for the waterproof board.

[0028] The reinforcing rod 3 is made of aluminum alloy to ensure that multiple reinforcing rods 3 are the same size. Aluminum alloy has high strength and relatively light weight, which can enhance the structural strength of the plate without increasing the overall weight of the plate too much. The reinforcing rod 3 is processed according to the size and spacing requirements of the first groove 4 and the second groove 5.

[0029] The top plate 1 and bottom plate 2 are made of color steel plate, which has a certain strength. Multiple aluminum alloy reinforcing rods 3 are set in the middle. The aluminum alloy has high strength, which can effectively enhance the overall load-bearing capacity and stability of the plate, making it less prone to deformation when subjected to external forces. It is suitable for various building roof waterproofing projects.

[0030] Prepare a polymer waterproof membrane layer. You can choose polymer materials such as ethylene propylene diene monomer (EPDM) or polyvinyl chloride (PVC). These materials have good waterproof performance, weather resistance and anti-aging properties.

[0031] High-strength polyester fiber nonwoven fabric is used, which can provide good flexibility and stability for waterproof layer 8 and enhance the overall performance of waterproof layer 8;

[0032] To prepare a self-adhesive modified asphalt layer, high-quality asphalt is mixed with special modifiers (such as SBS thermoplastic elastomer) and tackifiers, fillers, etc., to form a self-adhesive modified asphalt compound. This compound has self-adhesive properties at room temperature, making it easy to apply.

[0033] Multiple second grooves 5 are machined inside the top plate 1, and multiple first grooves 4 corresponding to the second grooves 5 are machined inside the bottom plate 2. The size and position of the grooves need to be precisely controlled to ensure that the reinforcing rod 3 can be tightly fixed therein;

[0034] The base plate 2 is provided with positioning holes 6 at its four corners, and the top plate 1 is provided with positioning blocks 7 at its four corners that are inserted into the positioning holes 6.

[0035] Positioning holes 6 are machined at the four corners of the base plate 2, and positioning blocks 7 that match the positioning holes 6 are machined at the four corners of the top plate 1. The size of the positioning blocks 7 should be able to be inserted into the positioning holes 6 to achieve precise positioning of the top plate 1 and the base plate 2.

[0036] A protective layer 9, a waterproof base layer 10, and an adhesive layer are laid sequentially on the upper surface of the top plate 1. First, a high-strength polyester fiber non-woven fabric is laid flat on the top plate 1 as the waterproof base layer 10.

[0037] Apply self-adhesive modified bitumen adhesive to the waterproof base layer 10 to form an adhesive layer. During the application process, ensure that the adhesive is evenly distributed to ensure the bonding effect with the upper and lower layers.

[0038] Lay the polymer waterproof membrane layer on the adhesive layer. When laying, take care to avoid problems such as wrinkles and bubbles in the membrane to ensure the waterproof performance of the protective layer 9.

[0039] The waterproof layer 8 consists of a protective layer 9, a waterproof base layer 10, and an adhesive layer. This multi-layered structure works synergistically to provide reliable waterproofing. The polymer waterproof membrane layer (such as EPDM rubber or PVC) has excellent waterproof performance and weather resistance, effectively preventing water penetration and providing long-term protection against environmental erosion.
