Problems solved by technology

[0002] Existing sound insulation boards are mostly made of organic and inorganic fibers, sponges, foam boards, etc., which have the following disadvantages: waterproof, fireproof, anti-aging, poor impact resistance, high energy consumption and environmental pollution, and pollution to the environment after being discarded. It cannot effectively absorb high, medium and low frequency sound waves at the same time. Therefore, in order to solve the above problems, a new technical solution is provided to meet the needs

Embodiment 1

[0025] A composite sound-insulating board, made of the following raw materials and their proportions by weight: 10% fly ash; 5% lime; 20% ethylene vinyl acetate resin; 3% wood pulp; 16% steel; 3% aluminum; The rest is magnesium.

Embodiment 2

[0027] A composite sound-insulating board, made of the following raw materials and their proportions by weight: 12% fly ash; 7% lime; 22% ethylene vinyl acetate resin; 6% Manila hemp; 20% steel; 6% aluminum; The rest is magnesium.

Embodiment 3

[0029] A composite sound-insulating board, made of the following raw materials and their proportions by weight: 15% fly ash; 10% lime; 25% ethylene vinyl acetate resin; 8% wood pulp; 22% steel; 12% aluminum; The rest is magnesium.

[0030] The advantages of the present invention are: ethylene vinyl acetate resin can block the noise of lower frequency, and can effectively prevent noise pollution when used in the sound insulation board, and the sound insulation board installed in the building can effectively prevent the outdoor noise from being transmitted to the room, and It avoids mutual interference between rooms, and can achieve good sound reduction and noise reduction effects in places where high noises are likely to occur, such as highways and railways, and effectively prevent and control noise pollution.

Abstract

The invention discloses a novel composite sound-insulation sheet material, which is characterized by comprising the following raw materials by weight percentage: 10-15% of fly ash, 5-10% of lime, 20-25% of resin, 3-8% of fibrous material, 16-22% of steel, 3-12% of aluminum and the balance of magnesium. The novel composite sound-insulation sheet material has the advantages that ethylene vinyl acetate resin can insulate low-frequency noise, can effectively prevent the noise pollution while being used in the sound-insulation sheet material, when the sound-insulation sheet material is arranged in the building, the outdoor noise can be effectively avoided for transmitting to indoor, mutual interference between each room can be also avoided, good sound attenuating and noise reduction effects can be reached in the places with large noise which is easily generated at highway and railway, so that noise pollution can be effectively controlled.

Description

technical field [0001] The invention relates to a composite sound-insulating board. Background technique [0002] Existing sound insulation boards are mostly made of organic and inorganic fibers, sponges, foam boards, etc., which have the following disadvantages: waterproof, fireproof, anti-aging, poor impact resistance, high energy consumption and environmental pollution, and pollution to the environment after being discarded. It cannot effectively absorb high, medium and low frequency sound waves at the same time. Therefore, in order to solve the above problems, a new technical solution is provided to meet the demand. Contents of the invention [0003] The object of the present invention is to provide a composite sound insulation board. [0004] The technical scheme adopted in the present invention is: [0005] A composite sound-insulating board, made of the following raw materials and their proportions by weight: [0006] Fly ash 10%-15%; [0007] Lime 5%-10%; [0...
