[0039] Example 4

[0040] The assembled building multifunctional composite assembly board produced by the above production process is subjected to the following performance tests:

[0041] 1. Thermal insulation performance test

[0042] The heat flow meter method was used to test the assembly board. Under standard test conditions (temperature difference of 25°C), the test results showed that the heat transfer coefficient of the assembly board was less than 0.35W / (m 2 ·K), compared with the traditional cement prefabricated board (heat transfer coefficient 0.8-1.2W / (m 2 ·K)) and aerated block materials (heat transfer coefficient 0.6-1.0W / (m 2 ·K)), which has significant advantages, indicating that it has good thermal insulation performance and can effectively reduce the energy consumption of buildings.

[0043] 2. Sound insulation performance test

[0044] According to relevant standards, the sound insulation test of the assembly board was carried out in the sound insulation laboratory. The results show that within the frequency range of 100Hz-3150Hz, the average sound insulation of the assembly board reaches 45dB. In the low frequency band (100Hz-500Hz), the sound insulation is about 38dB, which can effectively block low-frequency noise such as traffic; in the medium and high frequency band (500Hz-3150Hz), the sound insulation can reach more than 48dB, which can greatly reduce noise interference such as human voice and machine operation, and provide a quieter environment for the room.

[0045] 3. Fire performance test

[0046] According to the fire performance test method of building materials, the assembly board was tested for combustion performance. The test results showed that the combustion performance of the assembly board reached Class A non-combustible. Under the high temperature flame burning of 1000℃ for 3 hours, no open flame was generated on the assembly board, only slight carbonization on the surface, and the temperature of the back-fire surface was always below 180℃. When a fire occurs, it can effectively prevent the spread of the fire, provide valuable time for personnel evacuation and fire rescue, and significantly improve the fire safety performance of the building.

[0047] 4. Mechanical properties test

[0048] The assembly panels were tested for bending and compressive strength using a universal material testing machine. In the bending test, the ultimate bending strength of the assembly panels reached 8MPa. When subjected to uniformly distributed loads to simulate the stress conditions of the floor slab, it can meet the design requirements of general residential and commercial building floors and can withstand large horizontal loads. In the compression test, its vertical compressive strength reached 12MPa. When simulating the vertical pressure on the wall, it performed stably, met the mechanical requirements of the building structure, and ensured safety and stability during use.

[0049] Through the above tests, it can be concluded that the multifunctional composite assembly board of this prefabricated building has significant advantages in many aspects: in terms of thermal insulation, the heat transfer coefficient is as low as 0.35W / (m 2 ·K), far exceeding traditional materials, effectively reducing building energy consumption; in terms of sound insulation performance, the average sound insulation reaches 45dB, with good sound insulation effect in different frequency bands, which can create a quiet indoor environment; the fire resistance performance reaches Class A non-combustible, there is no open flame at high temperature and the temperature of the back fire surface is low, which effectively guarantees fire safety; in terms of mechanical properties, the ultimate bending strength is 8MPa and the vertical compressive strength is 12MPa, which meets the force requirements of the building structure and ensures safe and stable use. The overall solution provides high-efficiency, safe, energy-saving and environmentally friendly high-quality materials for prefabricated buildings.
