The surface sheet is made of a nonflammable material and is characterized by a lamination member made of any one of a material such as carbon fiber, metal fiber such as stainless fiber and amorphous fiber, ceramic fiber, inorganic glass fiber, and Teflon (registered trademark) .

The surface sheet may be made of a flame retardant material and may be formed by coating or impregnating a fire retardant or a fire retardant agent in leather, nylon, polyester, cotton, artificial leather or synthetic leather, coated with silicone, And a material obtained by kneading or impregnating a flame retardant, and the like.

The above-mentioned backsheet is characterized by a lamination member made of any one of a material having a high viscosity, such as a high shrinkage polyester, a high shrinkage acrylic, a high shrinkage nylon and a polyurethane, or a material composed of a mixture of these materials.

Further, the present invention is characterized by a lamination member in which a plurality of pores having a size of 100 mu m to 2 mm are formed on the surface sheet.

The top- and backsheets are characterized by a lamination member having a thickness of 0.1 mm to 5 mm and a surface of 1 mm to 20 mm.

The lamination member of the present invention can provide various finishing members and interior members having excellent elasticity, resilience, cushioning, and heat insulation by providing a surface on the intermediate layer of the three-layer lamination structure.

Further, it has become possible to increase the fire resistance or the flame retardancy by making the surface thereof a member having high nonflammability or high flammability.

Further, it is possible to enhance the damping effect of various sounds and vibrations generated in the room, inside or outside the vehicle, by providing the surface sheet with the concave / convex pattern using the sealing portion of the fixing chamber and / or by providing a plurality of pores. . In particular, it has become possible to enhance the damping effect of noise and vibration generated from inside buildings such as factories and music halls. In addition, in a music hall or the like, it is possible to improve the sound environment such as proper sounding of the sound due to the sound absorption effect and clarification of the single sound due to reduction of the noise.

In addition, it is possible to obtain various finish members and interior members having a very luxurious and high-quality finish and having a finished surface with aesthetic effect by selectively forming a surface sheet of a material excellent in material and color and uneven patterns of various shapes .

In addition, since the backsheet is made of a material having a high viscosity and the surface sheet side is made of a material having little shrinkage, the backsheet side is largely contracted and the surface side is small, so that a contraction difference occurs in the front and back sheets, So that the unevenness formed on the surface sheet can be further increased, and it becomes possible to improve the sound-absorbing property, the sound insulation and the dustproof property.

Further, for example, by laminating the lamination member of the present invention on an iron plate or the like and laying it in the vehicle, it is possible to prevent sound or vibration generated from the outside including the vehicle body from entering the vehicle. Therefore, it is possible to reduce the thickness of the steel plate or the like laid on the floor surface in the vehicle from the past, and to further improve the sound absorption effect and the anti-vibration effect.

In addition, it is possible to simply mount the building as a finishing material on partition walls of a mansion, an apartment, and a temporary house, thereby making it possible to prevent sound or vibration from an adjacent residential space.

1 is a plan view of one embodiment of a lamination member of the present invention;
2 is a cross-sectional view of one embodiment of a lamination member of the present invention;
3 is a cross-sectional view of another embodiment of a lamination member of the present invention;

Hereinafter, an embodiment of the present invention will be described based on the drawings.

Example 1

Fig. 1 is a plan view of a lamination member showing one embodiment of the present invention, and Fig. 2 is a cross-sectional view of the lamination member. The lamination member 1 is a three-layered lamination member provided with a surface 4 having elasticity, resilience and cushioning property between the topsheet 2 and the backsheet 3, The top and bottom sheets 2 and 3 are sealed with sealing means by the fixing chamber 5 in order to prevent movement in the vertical and lateral directions and to make the surface 4 to be mirror-finished .

The surface 4 as the sealing portion is crushed by the sealing of the front and back sheets 2 and 3 and the concave portion 6 formed continuously or intermittently is formed at the corresponding portion of the topsheet 2. The region other than the portion sealed by the fixed chamber 5 is formed with the convex portion 7 that bulges toward the topsheet 2 due to the elasticity of the surface 4. [ As a result, various patterns of irregularities are formed on the surface sheet 2 side. In addition to the following various materials, the topsheet 2 may be appropriately selected from various colors.

The concavo-convex pattern can be formed by a sealing portion of the fixed chamber 5, such as a rhomboid shape, a heart shape, a trifoliate shape, a polygonal shape such as a triangle, a rectangle, or a pentagon, a shape of various animals or plants, The shape of the building of the building, and the like.

In addition to the continuous sealing means as described above, various other shape patterns can be formed by point sealing or intermittent sealing.

The topsheet 2 is suitably selected from a material made of a high-quality material having flexibility and / or a material having a high-grade feeling and capable of expressing designability such as excellent color and various patterns. For example, it can be selected from suitable materials such as fabric, knitted fabric, nonwoven fabric, leather, synthetic leather, film, or laminated thereof.

As the topsheet 2, a non-flammable or flame-retardant material can be selected as required, and a material having fire resistance and flame retardancy as well as durability is selected. If necessary, the same material as the above can be selected for the fixed chamber 5 as well.

Specifically, as the incombustible top sheet 2 and / or the fixed chamber 5, a metal fiber such as carbon fiber or stainless fiber / amorphous fiber, a ceramic fiber, a glass fiber of an inorganic material, a Teflon coated fiber, Is used.

The flame retardant top sheet 2 and / or the fixing chamber 5 may be formed by applying or impregnating a flame retardant agent to leather, nylon, polyester, cotton, artificial leather or synthetic leather, A material obtained by kneading or impregnating a fire retardant or a flame retardant into the material itself is appropriately selected and used.

As the flame retardant, generally used organic flame retardant or inorganic flame retardant is used. Examples of the organic flame retardant include phosphorus-based flame retardants such as polyphosphate-based or phosphoric ester-based ones such as ammonium polyphosphate; and flame retardants such as nitrogen-based, halogen-based, and cancellous flame retardants. Examples of the inorganic flame retardant include a complex inorganic compound such as a boron compound, aluminum hydroxide, magnesium hydroxide, antimony trioxide, antimony oxygen, zirconium compound, sodium borate, zinc borate, molybdenum trioxide, sodium silicate or complex of the above compound. Particularly, a non-halogen flame retardant, particularly a polyphosphate flame retardant, which does not generate a harmful halogen-based gas at the time of fire or after incineration after use, is preferable.

The addition amount of the flame retardant is preferably 1 to 50 parts by weight per 100 parts by weight of the surface sheet. On the other hand, if the addition amount of the flame retardant is large, moldability is deteriorated and the unevenness becomes small, so that the physical properties of the topsheet 2 are deteriorated. In addition to the above components, the surface sheet 2 may contain other resins, inorganic decomposers, foam decomposition accelerators, lubricants, surfactants, anti-sticking agents, pigments, antibacterial agents and the like .

The thickness of the topsheet 2 is preferably in the range of 0.1 mm to 5 mm. If the thickness is thin, the sheet breakage tends to occur during molding, and in particular, when a hole is formed, the topsheet 2 may break from the portion. On the other hand, when the thickness is too large, the forming speed of the lamination member of the present invention is lowered, resulting in lowering of productivity and deterioration of workability at the time of secondary processing. A more preferable thickness is about 1 mm.

As the surface (4), any one of cotton, silk, cotton, cotton, wool fiber, synthetic wool, glass wool, rock wool and the like can be selected.

Further, similarly to the above, the surface (4) may be suitably selected from a non-flame retardant or a flame retardant which is applied or impregnated, or a flame retardant or flame retardant which is kneaded, or a non-floury glass wool or a lock. When the fire-retardant or flame retardant is used, the elasticity, the resilience, the cushioning property, the heat insulation property, the sound absorption property, the sound insulation and the dustproof property are not damaged. For example, it is possible to select to apply only to the front side.

The thickness of the surface 4 can be appropriately selected in accordance with necessity between 1 mm and 20 mm. Accordingly, besides the elasticity, the resilience and the cushioning property, it can be made excellent in heat insulation, sound-absorbing property, sound insulation, and dustproofness. Their performance improves as the thickness increases, but a more preferable thickness is about 10 mm in consideration of secondary workability, workability, and the like. In the case of an interior member requiring a corrugation such as a curtain, it is preferably 3 mm or less.

The backsheet 3 can be a fabric, a knitted fabric, a nonwoven fabric, a leather, a synthetic ladder, a film, or a laminated body thereof. In particular, the backsheet 3 can be made of lightweight, flexible, Is used. The backsheet 3 can be thermally shrunk by using a sheet having a high water resistance such as a woven fabric or a nonwoven fabric on the backsheet 3 so that the topsheet side with little contraction bulges and the topsheet 2 ) Can be further increased, and the effects of sound absorption, sound insulation, dustproofness and the like can be enhanced. The material of the backsheet 3 may be selected from high shrinkage polyester, high shrinkage acrylic, high shrinkage nylon, polyurethane and the like. In addition, a material obtained by mixing a material having a high shrinkage property with a material having a low shrinkage, for example, a material obtained by mixing a high shrinkage polyester with a low shrinkage polyester can be selected. Them 1: 0. 1 to 1: 5, it is possible to maintain a high viscosity. It is preferable that the thickness of the backsheet is in the range of 0.1 mm to 5 mm as in the case of the topsheet 2. A more preferable thickness is about 1 mm.

Depending on the place where it is used, it may be directly attached to the substrate side by pull attachment or bonding, so that a mounting face having an uneven face is formed by thread fabric, knitting or embossing process It is effective to improve the mounting strength with the substrate by performing coating or impregnation processing such as acrylic resin on the sheet.

The formation and sealing of the lamination members with the top- and backsheets 2, 3 and the face 4 may be performed simultaneously, or a time difference may be provided.

Example 2

3 is another embodiment of the lamination member 10, in which a plurality of pores are provided in the topsheet 11. It is possible to stack the layers of the surface 13 between the front and back sheets 11 and 12 to prevent the movement of the inside surface 13 by the sealing by the fixing chamber 14, And the surface 13 is mirror-finished to form the lamination member 10. The surface sheet 11 is provided with a concave-convex pattern on its surface and a plurality of pores 15 having a size of 100 to 2 mm.

Sound or vibration generated from the space or the outside can be absorbed into the small holes 15 of the topsheet 11 by using the side of the topsheet 11 of the lamination member 10 toward the surface side of the room, And it is possible to achieve absorption and vibration of sound, vibration or the like by entanglement of a plurality of fiber layers by the surface 13.

Although the first embodiment is also the same, a part of the sound impinging on the topsheet 11 due to a plurality of concave-convex patterns formed on the topsheet 11 is reflected in various directions, So that it is possible to attenuate the sound. In the case of the second embodiment, it is possible to attenuate sound, vibration and the like synergistically by attenuation by absorption of sound into the inner layer such as sound or vibration and reflection by sound.

Moreover, the laminated member is excellent in elasticity, resilience, cushioning, and heat insulation property by the predetermined thickness of the same surface 13 as in the first embodiment.

The backsheet 12 is suitably selected from the same as that of the first embodiment.
