Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a multifunctional composite thermal insulation and waterproof backing board. Background Art

[0002] Waterproof and thermal insulation backing board is a modern building material that combines waterproofing, thermal insulation, and other functions. It is typically used in building exterior walls or roof systems, designed to provide effective waterproofing and superior thermal insulation. The backing board utilizes advanced polymer materials and technologies, not only improving the durability and weather resistance of the waterproof layer, but also utilizing low thermal conductivity materials as the insulation layer, effectively reducing energy loss. Furthermore, to meet the requirements of building structures and facilitate construction, this product is designed with emphasis on mechanical strength and ease of installation. With growing environmental awareness, waterproof and thermal insulation backing board is also trending towards greener materials, striving to minimize environmental impact. In some cases, it also offers additional features such as fire resistance, moisture resistance, mildew resistance, and UV resistance, making it suitable for a wider range of applications. In short, waterproof and thermal insulation backing board represents an innovative trend in the building materials industry. Its versatility and high performance make it a vital component of modern architectural design.

[0003] While multifunctional composite waterproof and thermally insulating backing boards have made significant progress in the building materials field, existing technologies still have some drawbacks. Existing backing boards often lack the structural strength to withstand the mechanical challenges of harsh environments or long-term use. For example, traditional backing boards utilize a single material or a simple multi-layer structure, lacking effective reinforcement. This makes them susceptible to deformation or damage when subjected to external pressure, wind loads, or vibration. Furthermore, over time and environmental changes, these backing boards may experience material degradation, further weakening their structural stability. This problem is particularly prominent in high-rise buildings or in areas prone to earthquakes, where the backing boards must withstand greater external forces. Because backing boards cannot be spliced ​​together, users are limited by their size specifications when selecting backing boards, unable to customize them to their specific needs. This can lead to difficulties finding suitable products for specific size requirements. When backing boards do not meet the required dimensions, they must be cut to fit the installation space, which not only increases construction complexity but also can result in material waste.

[0004] In order to solve the above technical problems, the present invention designs a multifunctional composite thermal insulation and waterproof backing board. Utility Model Content

[0021] A multifunctional composite thermal insulation and waterproof backing board, characterized in that: it includes an insulation board 1, a first non-woven fabric layer 3 and a second non-woven fabric layer 4, the first non-woven fabric layer 3 and the second non-woven fabric layer 4 are respectively bonded to both sides of the insulation board 1 through an interface agent 2, and the first non-woven fabric layer 3 and the second non-woven fabric layer 4 are respectively provided with a first waterproof coating 5 and a second waterproof coating 6 on the side away from the insulation board 1, the first non-woven fabric layer 3 and the second non-woven fabric layer 4 include an upper non-woven fabric 31 and a lower non-woven fabric 33, and a reinforcing layer 32 is provided between the upper non-woven fabric 31 and the lower non-woven fabric 33.

[0022] The insulation board 1 is composed of expanded polystyrene board EPS, extruded polystyrene board XPS, rock wool board, phenolic insulation board or polyurethane foam board.

[0023] The first non-woven fabric layer 3 and the second non-woven fabric layer 4 are made of polyester non-woven fabric, nylon non-woven fabric or polypropylene non-woven fabric.

[0024] The first and second waterproof coatings 5 ​​and 6 are polymer or silicone coatings. Polyurethane (PU) or acrylics, for example, are sprayed or impregnated onto the nonwoven fabric to form a waterproof membrane. Silicone materials offer excellent waterproofness and breathability, making them suitable for applications requiring both waterproofing and breathability.

[0025] The thickness of the first waterproof coating 5 and the second waterproof coating 6 is between 0.1 mm and 1 mm. Coatings within this thickness range can form an effective waterproof barrier, preventing moisture from penetrating into the backing board, protecting the thermal insulation material from moisture, and extending the service life of the backing board.

[0026] The interface agent 2 is a polymer emulsion, a modified cement-based interface agent or a silane coupling agent.

[0027] Polymer emulsions are based on high molecular weight polymers such as acrylates and polyvinyl acetate. They provide good adhesion and form a film with a certain degree of elasticity after drying, which helps to relieve stress caused by temperature differences.

[0028] Modified cement-based adhesives: These are based on cement, with polymer emulsions and other additives such as cellulose ethers and silanes added to improve their bonding and crack resistance. They are suitable for applications requiring higher mechanical strength.

[0029] Silane coupling agent: Especially when the insulation board is an organic material such as polystyrene board EPS / XPS and the non-woven fabric is an inorganic material, the silane coupling agent can help improve the interface bonding between the two.

[0030] The reinforcement layer 32 can be a single-layer or multi-layer structure. It can be made of carbon fiber cloth, polyester fiber mesh, or fiberglass mesh. These materials significantly enhance the mechanical strength of the non-woven fabric layer and strengthen the overall structural stability of the backing sheet. In particular, they effectively disperse stress when subjected to external forces, reducing the risk of material damage. They also offer excellent weather resistance and maintain stable performance under varying climatic conditions.

[0031] Side waterproof strips 7 are also included. These strips are used along the side edges of the backing board. These strips are typically made of soft rubber or plastic and fit over the edge of the backing board and secured with adhesive. They effectively seal the edge gaps and prevent moisture from entering.

[0032] A slot 81 is provided on the side of the backing plate, and an inserting piece 82 is provided on the other side of the slot 81. The slot 81 and the inserting piece 82 are of the same shape.

[0033] It also includes a mounting plate, which is provided with embedded parts or reserved holes for being connected to the backing plate with screws.

[0034] A vibration-isolating washer or strip is installed between the mounting plate and the backing plate. These absorb and cushion external vibrations, preventing them from being directly transmitted to the backing plate, thereby protecting the backing plate from damage. By reducing the impact of vibration on the backing plate, the backing plate's service life can be effectively extended, preventing material fatigue or damage caused by long-term vibration.

[0035] When using, first ensure that the wall or structure surface where the backing plate is to be installed is flat, clean, and free of oil, dust or other impurities. Inspect the backing plate to ensure that it is intact and all accessories are complete.

[0036] If the side of the backing plate needs to be waterproof, first install the side waterproof strip 7 on the side of the backing plate, ensure that the waterproof strip fits tightly and is fixed with adhesive.

[0037] Fixed mounting plate: The mounting plate is provided with embedded parts or reserved holes for screw connection with the backing plate.

[0038] Place the mounting plate in the desired location and secure it to the wall or other structure using screws or specialized fasteners. Anti-vibration washers or anti-vibration strips may be placed between the mounting plate and the backing plate to reduce the impact of vibration on the backing plate.

[0039] Assemble the backing panels as needed: Slots 81 and inserts 82 are located on the sides of the backing panels. Insert the inserts 82 into the corresponding slots 81 to ensure a tight fit between the backing panels. Use waterproof tape to fill any gaps and ensure the joints are smooth and seamless.

[0040] Place the assembled backing plate on the mounting plate and connect them with screws or other fasteners. Check that the fastening is firm and that the backing plate is stable and does not shake.

[0041] After installation, check whether all joints and edges of the backing board are covered with sealing strips or waterproof coating to ensure good waterproofing effect.

[0042] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
