Detailed Implementation
[0023] like Figure 1As shown, this is Embodiment 1 of the present invention, applicable to unfinished houses and floors without underfloor heating. The high-performance floor insulation and soundproofing system includes a floor deck 1, an insulation and soundproofing layer, and a decorative surface layer 2. The floor deck 1 serves as the basic support structure, ensuring the overall structural stability. The insulation and soundproofing layer is fixed to the outside of the floor deck 1 by a leveling adhesive layer 3. A wall base isolation plate 4 is provided at the base of the floor deck 1. The wall base isolation plate 4 is vertically arranged and located at the end of the insulation and soundproofing layer, separating the end face of the insulation and soundproofing layer from the wall 10. The setting of the wall base isolation plate 4 effectively avoids direct contact between the end of the insulation and soundproofing layer and the wall 10, avoids the thermal bridging effect, and improves the overall durability and reliability of the system. The decorative surface layer 2 is located on the outside of the insulation and soundproofing layer and can be made of various materials such as ceramic tiles. The thickness of the leveling adhesive layer 3 is 10-18mm, and the thickness of the floor deck 1 is 100-130mm. By controlling the thickness of the leveling adhesive layer 3 and the thickness of the floor deck 1 within a certain range, standardized design can be achieved, which can simplify the subsequent construction process.
[0024] The thermal insulation and sound insulation layer uses water-based polyurea thermal insulation and sound insulation board 5, which has a thickness of 12-30mm to ensure high-efficiency thermal insulation and sound insulation performance. The water-based polyurea thermal insulation and sound insulation board 5 is fixed to the outside of the floor deck 1 through the leveling and bonding layer 3. A protective layer 9 is set between the decorative surface layer 2 and the thermal insulation and sound insulation layer. The protective layer 9 is a concrete layer or a cement-based self-leveling layer, selected according to construction requirements. The protective layer provides surface protection and leveling functions, and enhances the overall strength of the system. When the protective layer 9 is a concrete layer, the thickness of the concrete layer is 30-50mm; when the protective layer 9 is a cement-based self-leveling layer, the thickness of the cement-based self-leveling layer is 20-40mm.
[0025] The system in Example 1 exhibits excellent sound insulation, easily achieving a high standard of ≤60dB. Furthermore, the water-based polyurea insulation and soundproofing board 5 is fully bonded and fixed to the floor deck 1 and protective layer 9, eliminating cavities and preventing cracking of the protective layer 9. Construction is simple, quick, and has a short construction period, with economical and reasonable costs.
[0026] like Figures 2 to 4As shown, this is Embodiment 2 of the present invention, applicable to prefabricated floors with underfloor heating. The high-performance floor insulation and soundproofing system includes a floor deck 1, an insulation and soundproofing layer, and a decorative surface layer 2. The insulation and soundproofing layer is fixed to the outside of the floor deck 1 by a leveling adhesive layer 3. A wall base isolation plate 4 is provided at the base of the floor deck 1. The wall base isolation plate 4 is vertically arranged and located at the end of the insulation and soundproofing layer, separating the end face of the insulation and soundproofing layer from the wall 10. The setting of the wall base isolation plate 4 effectively avoids direct contact between the end face of the insulation and soundproofing layer and the wall 10, avoids the thermal bridging effect, and improves the overall durability and reliability of the system. The decorative surface layer 2 is located on the outside of the insulation and soundproofing layer and can be made of various materials such as ceramic tiles. The thickness of the leveling adhesive layer 3 is 10-18mm, and the thickness of the floor deck 1 is 100-130mm. By controlling the thickness of the leveling adhesive layer 3 and the thickness of the floor deck 1 within a certain range, standardized design can be achieved, which can simplify the subsequent construction process.
[0027] The thermal insulation and sound insulation layer uses water-based polyurea thermal insulation and sound insulation board 5, with a thickness of 12-30mm, ensuring high-efficiency thermal insulation and sound insulation performance. The water-based polyurea thermal insulation and sound insulation board 5 is fixed to the outside of the floor deck 1 via a leveling adhesive layer 3. A foamed ceramic board 6 is installed on the outside of the water-based polyurea thermal insulation and sound insulation board 5. The water-based polyurea thermal insulation and sound insulation board 5 and the foamed ceramic board 6 form an integrated composite structure, with the foamed ceramic board 6 having a thickness of 25-40mm. A decorative surface layer 2 is fixedly connected to the outside of the foamed ceramic board 6 via an adhesive layer 7, with a thickness of 3-8mm. An installation channel 8 is provided on the outer surface of the foamed ceramic board 6 for the installation of underfloor heating pipes. The water-based polyurea thermal insulation and sound insulation board 5 and the foamed ceramic board 6 are factory-processed composites, and together with the underfloor heating pipes laid through the installation channel 8, integrated thermal insulation, sound insulation, and underfloor heating are achieved.
[0028] The system in Example 2 has a pre-installed installation path for the underfloor heating pipes, which is quick, effective and safe. Compared with Example 1, it eliminates the need for the construction of the protective layer 9, reduces the number of procedures, shortens the construction period, and enables assembly. Furthermore, eliminating the protective layer 9 can improve the heat release speed and efficiency of the underfloor heating, and avoids the problem of the protective layer 9 cracking due to underfloor heating, which would affect the stability of the decorative layer.
[0029] The water-based polyurea insulation and soundproofing board 5 in this application uses water-based polyurea foam as a functional carrier. Water-based polyurea foam has excellent thermal insulation properties, ensuring a reduction in the overall thickness of the insulation and soundproofing system. Water-based polyurea foam has a μm-level closed-cell structure, exhibiting good sound insulation based on the principle of "micropore damping." As a thermosetting foam, water-based polyurea foam easily meets B1 fire resistance requirements and exhibits no dripping, effectively preventing fires. Water-based polyurea foam also possesses excellent mechanical properties, with superior comprehensive performance in terms of compressive strength, tensile strength, and dimensional stability. Furthermore, water-based polyurea foam has good waterproof, antibacterial, and insect-proof properties, making it more suitable for indoor environmental protection.
[0030] This application introduces a flexible element into the foaming process of the water-based polyurea foam, improving its flexibility. While microporous damping sound insulation is a superior performance characteristic of water-based polyurea, achieving high-standard sound insulation with minimal thickness still falls short. Therefore, it is necessary to improve the flexibility of the foam to absorb the mechanical vibration energy of sound waves, achieving a dual-channel effect of "absorption + damping" to achieve high-performance sound insulation. This application transforms the molecular structure of the foam through formula adjustments, upgrading it from a conventional polyurethane (PUR) structure to a water-based polyurea structure, resulting in better fire resistance. Furthermore, the introduction of a halogen-free flame retardant reduces smoke density and toxicity, improving fire prevention and disaster relief capabilities for escape and rescue. Moreover, this application abandons traditional fluorinated foaming agent technology, adopting a fully water-based foaming technology, thoroughly meeting the requirements of the national environmental protection policy and simultaneously improving indoor environmental quality.
[0031] This application describes a streamlined composite production process. During online water-based polyurea foaming with a fixed thickness, double-sided fiberglass nonwoven mortar cloth is introduced, ultimately producing a thermal insulation and soundproof composite board. The mortar cloth enhances the overall strength of the board and provides an adhesive interface for the system's structural stability.
