[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 In an embodiment of the utility model, a lightweight noise reduction and sound insulation board includes a fireproof layer 1, a sound insulation layer 2, a first supporting layer 3, a noise reduction layer 4, a second supporting layer 5, an anti-corrosion layer 6 and a waterproof layer 7 which are arranged in sequence from top to bottom, and each layer can be assembled by bonding.

[0021] The fireproof layer 1 is made of glass wool material, which is a heat-insulating material. It is non-flammable, has good high-temperature resistance and is light in weight. The thickness of the fireproof layer 1 is 3mm-4mm. The sound insulation layer 2 is made of polyester fiber material, which is a fiber porous sound insulation material. There are a large number of tiny interconnected pores inside the material. Sound waves can penetrate into the material along these pores, and the friction with the material converts the sound energy into heat energy, which can achieve good sound insulation and heat preservation effects. The thickness of the sound insulation layer 2 is 3mm-4mm. The first supporting layer 3 and the second supporting layer 5 are both made of metal aluminum material. Aluminum has a good sound insulation effect, and it can also prevent fire, absorb energy, and prevent radiation. The material is also relatively light. Aluminum also facilitates improving the overall strength of the board. The thickness of the first supporting layer 3 and the second supporting layer 5 are both 1.5mm-2mm.

[0022] The anti-corrosion layer 6 is made of vinyl ester resin material (VE), which is a thermosetting resin. It is light, strong and also a good corrosion-resistant material. It is suitable for applications in various fields. The thickness of the anti-corrosion layer 6 is 2mm-4mm. The waterproof layer 7 is made of ethylene-vinyl acetate copolymer (EVA) material. The EVA material is very light, wear-resistant, corrosion-resistant, waterproof and has a buffering effect. The thickness of the waterproof layer 7 is 2mm-4mm.

[0023] The top and bottom of the noise reduction layer 4 are provided with multiple groups of equally spaced trapezoidal grooves 8, and a front-to-back through-noise chamber 9 is provided between two adjacent groups of trapezoidal grooves 8 in the noise reduction layer 4. The noise reduction layer 4 is provided with multiple groups of perforations 10 that penetrate the sound reduction chamber 9 from top to bottom. The noise reduction layer 4 has a built-in complex porous structure, which can effectively absorb the energy of noise sound waves, reduce the reflection and echo of internal sound, and reduce indoor reverberation, thereby improving the overall noise reduction effect of the sound insulation board. The noise reduction layer 4 is made of wood, and the thickness of the noise reduction layer 4 is 8mm-10mm.
