First sound insulating plate portion (A) upper cover layer (1), first sound insulating plate portion (A) foam foam layer (2), first aqueous EVA adhesive layer (3), second sound insulating plate portion (B) foam foam layer (4), first Aqueous EVA adhesive layer (5), 3rd sound insulation board part (C) foam foam layer (6), 3rd sound insulation board part (C) lower cover layer (7).

The present invention relates to an interlayer noise preventing mat. The first sound insulation panel part is made of a soft PVC material having a predetermined thickness and having an excellent effect of reducing the interlayer impact sound and noise of buildings by different density and physical properties (elasticity, voids, etc.). It consists of a three-stage layer using aqueous EVA bonding of (A) and the second sound insulating plate portion (B), the third sound insulating plate portion (C), the first sound insulating plate portion (A) is the primary shock and noise transmitted from the upper surface The shock and noise transmitted by being distributed and absorbing most of the shock and noise are absorbed in the second sound absorbing panel part B having a lower density and excellent elasticity and voids. The shocks and noises transferred to the floor are absorbed and dispersed in the soft third sound absorbing panel part C, which is more dense, and absorbs and blocks the noises generated in each floor of the building sequentially. It relates to a PVC mat for noise protection and a method of manufacturing the same.

The noise transmission between floors of MDUs can be divided into 'airborne noise' and 'shock noise'. If you play a musical instrument such as a piano or raise the volume of audio or TV to make noise damage to neighbors, you can classify it as air noise. Noise that falls downstairs from objects dropping upstairs or children jumping off the couch is classified as impact noise. In Korea, the apartment is a wall structure in which the wall bears the load, so the solid noise, that is, the structure noise is transmitted along the wall. In the case of multi-unit buildings such as apartments or multi-storey buildings, most of the airborne sound is blocked by the concrete slab structure.However, when a shock or vibration is applied directly to the floor by human walking or falling objects, It is variable and hardly attenuated and radiates through floor slabs, ceilings or walls into lower floors or into adjacent generations. These "bottom shocks" are lightweight impact sounds that generate a lot of high frequency components such as falling sounds of bowls or objects, and heavy impact sounds that generate a lot of low frequency components such as adult walking or children's skipping. It is rough. Impact noise also differs in how the slab plate supports the interlayers, but by varying the properties of the media of the slab layer, it is much more effective in preventing the interlayer impact noise. Inserting another medium in the middle of a slab of the same thickness will block more impact noise. In the case of Gumi houses, heavy impact sound is generally the main, but in Asian cultures such as Korea, both heavy impact sound and light impact sound are generated, and floor shock sound reduction materials between buildings are required to prevent propagation.

Existing high-rise buildings require a high cost in the separate construction, and due to the realistic problem that can be seen only if the construction in all the floors are expected to prevent noise enough to lay a separate foam or foam sheet on the floor.

In recent years, the construction of buildings has become higher and higher, especially residential apartments, so as to reduce construction costs and to reduce loads. I use a prevention pad.

On the other hand, the interlayer anti-noise pad is typically formed of a single material of foam foam resin material capable of absorbing and blocking noise. In recent years, a plurality of air holes penetrated up and down are formed on a plate made of a single material, and an interlayer noise material that resonates vibrations or noises in the air holes to increase its sound absorption effect has been proposed.

Korean Patent Publication No. 10-549161 discloses a flexible polyurethane composition for reducing the impact noise between buildings by spraying hardening time by reducing the spray-type curing time while at the same time obtaining excellent physical properties of the impact between buildings. And the soft polyurethane spray foam structure is described,

Korean Patent Laid-Open Publication Nos. 10-2005-77218 and 10-2005-77219 include two or more layered separation structures in an interlayer noise suppression structure, each having a thickness of 2 to 30 mm in a polyethylene foam foam body, Polypropylene foam foam, polystyrene foam foam, ethylene vinyl acetate foam foam, polyvinyl chloride foam foam, thermoplastic elastomer foam foam, synthetic rubber foam foam, a single component or two impressions selected from the sound insulating sheet material filled with an organic polymer material The interlayer noise prevention material consisting of two or more layers of main body of two or more layers having a thickness of 2 to 30 mm and a thickness of 3 to 6 mm of each layer is described.

The sound insulation effect of the interlayer noise prevention pad made of a single material is different depending on the thickness of the composition.In general, when the production is less than 21mm, the noise and vibration absorbing effect is less than the standard value. It can be expected to absorb noise and absorb noise. However, when the floor surface of each floor is laid or constructed by using interlayer noise prevention pads thicker than 30mm in order to increase the sound insulation effect, the floor surface is soft and the floor surface is inclined due to the weight of the person living or residential goods. There was a problem that the safety is reduced. In addition, the construction method of the polyurethane-based interlayer sound insulation material is to produce polyurethane-based compositions having different physical properties individually in the factory, and to apply and laminate them, which requires more than 2 hours to fully cure and when curing There is a problem that heat is generated, causing an odor. In addition, the felt, such as non-woven fabric has a problem that the sound insulation effect is inferior compared with other structures of the same thickness, both have a problem that a high cost for flame retardancy occurs.

In order to solve the problems as described above, the present invention improves the sound insulation with a thin thickness compared to the existing structures with a thickness of 21 ~ 30mm while using a multilayer structure of PVC foam having different density, hardness, and physical properties. Improved bottom tilt and safety. In addition, it is a soft composition for reducing the interlayer impact sound of the building, which is easy to install and dramatically shortens the construction time while providing excellent physical properties with the effect of reducing the interlayer impact sound of the building that can be worked without the additional construction process and time required. It is a technical problem to be achieved by the present invention to provide a composition and a method of manufacturing the PVC mat for interlayer noise blocking.

PVC foamed foam resin having different physical properties (density, hardness, cell structure, etc.) of the present invention for achieving the above object by using aqueous EVA bonding, hot plywood, the impact transmitted from the outside (noise, vibration, etc.) The present invention relates to a PVC mat for interlayer noise blocking and a method of manufacturing the same.

The third sound insulating plate portion C is composed of a foamed foam layer 6 having a density of 0.165 g / cm 3 and a lower label layer 7 having a density of 1.25 g / cm 3.

Since the third sound insulation plate part C is located at the bottom end, the seating property of the third sound absorbing plate C is improved, and the close-cell and open-cell structures are mixed. The effect can be achieved at the same time.

The upper cover layer of the uppermost sound insulation panel portion A and the lower cover layer of the lowermost third sound insulation panel portion C are vacuum-embossed to widen the body surface area to have dispersion effect on noise. .

The noise is mostly absorbed while passing through the structures of different physical properties, and the sound absorbing effect is further increased in the pores of the inner cell, thereby preventing the noise generated from each floor of the building from being transmitted to the lower floor.

As shown in FIGS. 2 and 3, the upper cover layer 1 of the first sound insulating plate part A is formed of 48 to 50 g of PVC having a degree of polymerization of 1,550 to 1,650, and a plasticic or carboxylic acid plasticizer. 33 ~ 35g , 1 ~ 2g thermal stabilizer made of potassium zinc composite, 4 ~ 5g organic and inorganic pigment, 14 ~ 16g filler of calcium bicarbonate are formed by kelizing the composition, gelling temperature is 100 ~ 170 ℃ The thickness is 0.15 ~ 0.25mm is good.

Embossing. Vacuum embossing does not deform and influence the shape and structure of the cell's pore cell that has the greatest effect on sound absorption and sound insulation because it forms the pattern by adsorbing the surface by vacuum rather than compression compared to conventional embossing. And can emboss deeper embosses. In addition, in the second process, the surface printing treatment is possible, thereby providing an appearance effect when used for the purpose of preventing noise between floors of an existing building.
