AI Technical Summary
Existing sound insulation materials, while improving sound absorption and noise reduction, struggle to simultaneously provide fire resistance and thermal insulation, especially in high-temperature environments where safety and sound insulation are inadequate.
It adopts a multi-layer structure design, including a honeycomb panel, a flow guiding layer, a fireproof layer and a base plate layer. The flow guiding layer is made of ceramicized polyolefin or glass fiber mesh, and the base plate layer is composed of polyurethane foam. Through the synergistic effect of each layer, sound waves are dispersed, absorbed and attenuated, while also having good fire resistance.
It achieves effective absorption and attenuation of noise in different environments, has good fire safety and thermal insulation performance, and is suitable for places with high acoustic and fire protection requirements such as building interior walls, machine rooms, and tunnels.
