Description

Soundproofing Sheet for Reducing Floor Shock

The present invention relates to a sound insulating sheet for reducing the floor impact, in particular through the porous polyester fiber and a plurality of laminated structure can effectively block the light impact sound and heavy impact sound generated when the floor impact of the building and reduce the occurrence of dust during manufacturing The present invention relates to a sound insulating sheet for reducing a floor impact that can improve an environment.

In general, in order to prevent noise between floors of residential buildings such as office buildings or apartments, the sound insulation sheet is interposed between floors that form each floor, and construction is carried out to block the noise generated while living on the upper floor. have.

In such a floor structure of apartments, houses, and public facilities, impact sounds are classified into light impact sounds and heavy impact sounds, and lightweight impact sounds are coins falling or high heels stuttering. Although possible, the heavy impact sound is a dull sound such as children playing, and the existing sound insulation material and the existing floor structure is difficult to reduce the weight impact sound.

In general, the floor structure of apartment houses and public facilities uses floor buffers made of various inorganic materials, organic materials, and polymers for the purpose of sound insulation and dustproofing. have:

Synthetic resin composition such as EVA in which asphalt Pe film is mixed with inorganic filler such as calcium carbonate, clay, talc, bentonite, barite mainly containing barium sulfate

-Pe film deposits with functional fillers on fibrous felt

-Composite and styrofoam mixed with cork and rubber

-Inorganic materials such as gypsum board and rock wool.

However, these materials exhibit considerable vulnerabilities in problems such as sound insulation performance, workability, and economics, making them difficult to practically use.

For example, it is difficult to expect as much as the production cost is expensive or to have insulation and soundproofing and dustproofing effect.

In the case of the waste tire chip, which has attracted much attention recently, it is of great value in terms of utilizing waste materials, but the particle or density of the rubber is not constant and hardening and carbonization occur over time. Therefore, it is difficult to expect desirable heat insulation, sound insulation, and dustproof effects.

A typical example of the sound insulation sheet for reducing the floor impact as described above is shown in FIG.

In Figure 1, the member number 1 is a fibrous felt, 2 is an asphalt layer, and 3 is a polyethylene film.

As shown in the drawing, the conventional sound insulation sheet for reducing the floor impact is coated with asphalt (2) to increase sound insulation and waterproof effect to the upper and lower sides of the fibrous felt (1) and the fibrous felt (1) formed in a constant thickness and on both sides. The polyethylene film 3 is adhesively formed on both sides of the coated asphalt 2.

However, the sound insulation sheet for reducing the floor impact as described above uses porous fibrous felt and asphalt for waterproofing, but forms a simple laminated structure laminated only with fibrous felt and asphalt to completely block heat and sound energy. There was a problem that the heat insulation effect or waterproof effect is lowered.

In addition, the sound insulation sheet for reducing the floor impact is a simple laminated structure can block a simple lightweight impact sound, but there was a problem that the blocking of heavy impact sound is not perfect.

Accordingly, the sound insulation sheet for reducing the floor impact proposed by the present applicant in Utility Model Registration Application No. 2003-11399 forms a multi-layered structure in which glass fibers and asphalt asphalt are laminated to reduce the floor impact to improve the effect of heat insulation, soundproofing, and waterproofing. However, the above sheet has a problem of damaging the worker's respiratory system due to the glass powder when producing the sheet by using glass fiber, and the glass fiber is less abrasion resistant, brittle, and has a specific gravity of 2.2. There is a problem that the sheet is broken or heavy because of 1.7 times the size of the cotton, and the upper side of the sound insulating sheet is formed of polyethylene film has a problem that is easily broken during construction.

The present invention has been devised in view of the above-mentioned problems of the prior art, to form a multi-layered structure of polyester fibers and ascones to compensate for the disadvantages of glass fibers, and to laminate the polyolefin foamed resin panel to the upper side, thereby reducing the volume of the sound insulating sheet. The purpose of the present invention is to provide a sound insulation sheet for reducing the floor impact that can improve the effect of heat insulation and sound insulation and waterproof while preventing the damage to the sound insulation sheet.

In order to achieve the above object, a central ascon layer having acid resistance and moisture resistance in the center, a polyester fiber layer formed of a porous fiber layer on both sides of the central ascon layer, and an acid resistance on the upper and lower sides of the polyester fiber layer, It characterized in that the upper and lower ascon layer having a moisture resistance, and a polyethylene film laminated on the outer side of the upper and lower ascon layer, and the polyolefin foamed resin panel of the moisture-absorbing insulation is absorbed on the upper side of the ascon layer. The upper side of the upper ascon layer provides a sound insulating sheet for reducing the floor impact, characterized in that the non-woven fabric is laminated with a natural foamed rubber.

As shown therein, the sound insulation sheet for reducing the floor impact of the present invention is formed of a waterproof layer having acid resistance and moisture resistance and a fibrous layer having the nonflammable and heat insulating effect.

The sound insulation sheet for reducing the bottom impact is to form a central ascon layer (10) in the center of the center ascon layer 10 on both sides of the polyester fiber layer 20, but the polyether fiber layer (20) Is formed of a porous fibrous layer.

The upper and lower sides of the polyester fiber layer 10 formed as described above are laminated with a plurality of upper and lower ascon layers 30 and 31 having acid and moisture resistance, and the polyethylene film 40 is laminated to the outer side of the upper and lower ascon layers 30. do.

In addition, the sound insulating sheet for reducing the bottom impact absorbs a shock to the upper side of the ascon layer 20 as shown in FIG. 3 and forms a polyolefin foamed resin panel 50, which is a moisture-proof insulating material, as shown in FIG. As described above, it is preferable that the upper layer of the upper asphalt cone layer 30 is laminated with a natural foamed rubber 70 to which the nonwoven fabric 60 is bonded.

Ascon as described above has acid and moisture resistance, and the polyester fiber is formed of a high-density fiber having a nonflammable and heat insulating effect.

In addition, the said polyester fiber is all the polymer which the ester group has a coupling group is polyester.

The polyester-based synthetic fiber is composed of ethylene glycol and terephthalic acid, which is porous, less brittle, lighter, more flexible, and more flexible than other glass fibers. Of course, the sound absorption performance is high.

In addition, the polyolefin foamed resin panel and the natural foamed rubber can lower the absorbency and lower the thermal conductivity coefficient to maintain the insulation and prevent breakage by the cushion force.

The heat and negative energy blocking characteristics of the monolayer material and the porous material are shown in FIGS. 4 to 5.

In addition, ascon has high chemical resistance and water resistance, and it is used for the purpose of acid and moisture resistance by dissolving bitumen in a solvent and drying and solidifying the solvent by evaporation.

The sound insulation sheet for reducing the floor impact as described above is very high sound insulation of dull low frequency sound, and also has excellent sound absorption properties for high frequency sound, it is also preferable to mix the stone powder with the ascon to increase the specific gravity of the sound insulation sheet.

After forming the polyester fiber on both sides of the ascon and applying the ascon on both sides of the polyester fiber, the multi-layered structure in which the polyolefin foamed resin panel and the natural foam rubber and polyethylene film are bonded to form a waterproof layer to facilitate application to the wet structure. In addition, the fibrous structure is excellent in absorbing shock by virtue of its role as a spring, and has low non-elasticity and excellent vibration absorption compared to rubber and foamed organic products.

In addition, the excellent sound-absorbing performance of the polyester fiber is excellent in noise blocking even when applied to a single layer structure, a simple laminated structure and a plurality of laminated structures.

In addition, the fibrous porous structure maintains a porous phenomenon of converting sound energy into thermal energy, so that the sound due to impact vibration is not re-radiated, and thus the sound insulation effect is excellent.

On the other hand, indoor floor structure such as Korea is made of unique structure called ondol, so the insulation property of the interlayer noise prevention material has more influence than other countries, and this insulation property prevents heat loss from the floor and continuously radiates heating heat. As the sound insulation sheet must be prevented from aging, the rubber material, which is a conventional single layer structure, loses its flexibility, and thus the effect of preventing noise is lowered. Therefore, at temperatures below 100 degrees, almost no change in physical properties and light polyester fiber or ascon are semipermanent. It can be used as an effect.

As described above, the present invention forms a multi-layered structure of polyester fiber, ascon and polyolefin foam resin panel, and natural foam rubber to reduce the volume and weight of the sound insulation sheet and improve the effect of heat insulation soundproof and waterproof, and manufacture the product. As dust does not occur, worker health can be maintained and it is not damaged by impact, which increases the efficiency of the product.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments, and the general knowledge in the art to which the present invention belongs without departing from the spirit of the present invention. Various changes and modifications will be possible by those who have the same.
