Description

Interlayer Noise Reduction Material with Functional Glyphs {The construction materials}

The buildings of apartments or multi-unit houses are composed of upper and lower floors, bounded by concrete slabs, and the impact sound generated by striking the upper floors in turn transmits the impact sound to the floor concrete slab through the floor finishing material layer, boiler pipe layer, and aerated concrete layer. It goes down to the lower floor, which causes a lot of noise due to noise.

The fundamental solution to reducing the floor impact sound is the first to make no noise, but it is almost impossible in real life, so there is a need for a method that can minimize the noise by maximizing reflection or sound absorption in the process of the impact sound being transferred to the concrete slab.

In the past life, there were few apartment houses such as apartments, and most of them lived in the form of single-family houses, so there was a lack of awareness of noise and indifference. As quality improves, the demand for maintaining a comfortable living environment and individual privacy is increasing, and the demand for soundproofing and sound absorbing materials is increasing.

Such soundproofing and sound absorbing building materials require the following characteristics.

1. Light weight: The product should be light in weight and have good tensile strength and thin in order to reduce the thickness between layers.

2. Insulation, Sound Insulation, and Dust Resistance: As a compression molded product, it is excellent in insulation and dust resistance, and is excellent in sound absorption and sound insulation by minute bubble holes existing in the product by foam molding.

3. Workability: It should be easy to mold and manufacture and workability is fast and simple.

4. Eco-friendliness: If polymer waste scraps or industrial wastes can be recycled, it is very environmentally friendly because it is very effective in protecting the natural environment and saving resources.

5. Flame retardant: Fire retardant, non-flammable properties should be good.

6. Ease of use: It should be easy to use with simple tools.

7. Economics: The cost of construction should be low.

8. Design: If the soundproofing and sound absorption have an excellent pattern and design, it can be made thinner than similar soundproofing and sound absorbing materials.

Recently, due to the development of industrial technology and the improvement of living standard, the demand for low vibration and low noise products is rapidly increasing, and the noise standard is regulated by law due to environmental and health problems caused by noise and vibration. As a result, building materials for sound insulation and sound absorption have been developed in various forms such as soundproofing materials, vibration damping materials, dustproof materials, sound absorbing materials, and soundproofing materials.

The damping material is a material that absorbs mechanical energy such as vibration and sound as thermal energy due to deformation of the material, and asphalt-based compositions and iron sheets have been typically used. However, asphalt-based vibration dampers have the disadvantages of poor quality and limited use, non-flammability, and inability to meet the required specifications. Metals such as steel are heavy and easily oxidized. there is a problem.

Anti-vibration material is a material to prevent the transmission of vibration generated from the vibration source, but used a dust-proof rubber, but this is difficult to regenerate, expensive, difficult to maintain the form at high temperature, and the elastic modulus decreases in the cold for a long time There are problems such as not being able to.

Sound absorbing materials have been used as a material for minimizing sound waves reflected by absorbing sound waves, such as asbestos, but this material has a health problem such as causing lung cancer.

The sound insulating material is a material that blocks and reflects sound waves to prevent energy transmission, and it is common to use a high-density filler such as metals mixed with a resin, but there are some problems in terms of flexibility and moldability.

Looking back at past examples of trying to solve these problems,

In the Republic of Korea Registered Room No. 20-0252799 described a soundproof plate using a waste tire chip, but the product is heavy and difficult to mold,

Korean Patent Laid-Open Publication No. 2003-0013495 describes a method for manufacturing sound absorbing materials between a layer of multi-family housing using waste tire rubber chips and cork powder and its products. However, when manufacturing the product, it is necessary to use cork powder of specific wood and it is difficult to recycle after construction. There is this.

In the Republic of Korea Registered Room No. 20-0280783 has been described with respect to the building styrofoam panel in which the elastic rubber ball is fused, the rubber ball has an insulation effect is unknown and there is a disadvantage that the recycling of strofoam is difficult.

In the Republic of Korea Registered Room No. 20-0262810 described the soundproofing, sound-absorbing insulation material protruding pyramidal projections, but there are disadvantages in manufacturing and construction difficult,

Korean Patent Laid-Open No. 2002-0085025 describes a composition for sound insulation and vibration prevention material having electromagnetic wave and water wave absorption ability and a mat using the same, but it is a product that focuses more on water wave blocking than sound absorption.

In the Republic of Korea Registration No. 20-0259046 described the prefabricated floor-floor soundproof structure with the sound absorbing material is inserted, but the description of the method of assembling the floor rather than the sound absorbing, soundproofing function.

Korean Patent Laid-Open Publication No. 1998-069083 describes a curved sound absorbing plate for building and its manufacturing method and apparatus, but it is a simple description of the production equipment of the sound absorbing plate with convex protrusions.

In Korean Patent Laid-Open Publication No. 2003-0008801, a building material including waste ethylene vinyl acetate and a manufacturing method thereof have been described, but mixing of two polymer materials having different molding methods may cause difficulties in the work process.

Therefore, in order to solve the above problems, the purpose of the present invention is to insert a special design with excellent soundproofing and sound absorption function, noise and impact sound transmitted from the upper floor of the concrete slab to the lower floor of the indoor floor bounded by the upper and lower floors such as apartments or apartment houses. The purpose is to provide a pleasant living environment by manufacturing and installing building materials that significantly reduce the cost.
