Description
The present invention relates to a sound absorbing board and a method of manufacturing the same, and more particularly, to a sound absorbing board capable of forming a texture and design of Korean paper using sound absorbing paper using a large amount of irregular and irregular wrinkled Korean paper, ≪ / RTI >
Sound absorption is a process of eliminating or reducing the energy of a sound, which is carried out by sound absorption by friction of a multi-pore sound absorbing material, sound absorption by a plate vibration with an air layer on a wall surface, and sound absorption mechanism using a single resonator . Although the porous sound absorption varies depending on the thickness, the sound absorption effect in the wide frequency band is excellent, but the finishing in itself is not suitable, and the sound absorption due to the plate vibration increases the sound absorption rate in the low frequency region, . It is understood that sound absorption by a single resonator exhibits a high sound absorption effect only in a narrow frequency band.
Glass fiber, rocky surface or gypsum board is currently used as a sound absorbing material for interior or exterior use. These materials have been applied to building structures due to their relatively good sound absorbing effect and thermal insulation. However, when they are exposed to air, they are harmful to the human body due to dust and the like. Because of its weakness, a certain frame for storing sound absorbing materials is separately required, which is disadvantageous in terms of space utilization. Therefore, development of an environmentally friendly sound absorbing material capable of replacing these sound absorbing materials is required.
It is an object of the present invention to provide a sound absorbing board capable of preserving the characteristics of environment-friendly paper even when attached to the board surface.
The present invention provides a sound absorbing board capable of enhancing sound absorption while maintaining texture and design of Korean paper.
One aspect of the present invention is
Board for architectural use;
A first portion attached to the upper surface of the board; And
And a coating layer formed on the paper.
The above-mentioned paper relates to a sound absorbing paper board having a plurality of corrugations formed thereon.
In another aspect,
Forming a wrinkle on the paper;
Attaching a wrinkled sheet to an upper surface of a board; And
And a step of forming a coating layer on the paper. .
The sound absorbing paperboard of the present invention can increase the sound absorption performance in a wide frequency band region by using the wrinkled zoomed-in paper. In addition, the sound absorbing paperboard of the present invention can further improve the sound absorption performance because the size and irregularity of the irregularities are increased due to the soft white powder added to the wrinkled paper.
In addition, when the finished product is terminated, it can be seen that the base panel and the part where the paper is bonded are not bonded. In this case, a space is formed between the paperboard and the base panel of the non-adhered portion, thereby absorbing and extinguishing the sound.
Since the sound absorbing paper board of the present invention is attached to the upper surface of the board, it is not only environmentally friendly as compared with glass fiber, rock face, or gypsum board, but also can enjoy the luxurious and aesthetic design and texture of Korean paper with wrinkles.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, and this may vary depending on the intention of the user, the operator, or the like. Therefore, the definition should be based on the contents throughout this specification.
FIG. 1 is a sectional view of a sound absorbing board according to an embodiment of the present invention, FIG. 2 is a perspective view of a sound absorbing board according to an embodiment of the present invention, FIG. 3 is a schematic cross- FIG. 4 is a conceptual sectional view of a sound absorbing paper board manufactured by laminating two sheets of zoom paper, and FIG. 5 is a photograph of the manufactured sound absorbing paper board.
1 to 3, the sound absorbing paper board of the present invention includes a built-in
The built-in
The
The above-mentioned
Referring to FIGS. 2 and 3, a plurality of the
The wrinkles may be regularly formed at predetermined intervals, but are preferably formed in an irregular size and direction, and the wrinkles may be connected to adjacent wrinkles to form an irregular net structure. That is, it can be understood that the irregularly projecting region A of the corrugations forms a network skeleton, and the non-projecting region B forms pores. Here, the atypical network (net) indicates that the shape and size of the network are not standardized.
The corrugation may be formed on the surface of Korean paper at a height of 5 mm or less, preferably 2 mm or less, more preferably 0 to 1 mm or 2 mm.
The
The pulp and the dough fiber provide a basic structure of paper having a network structure including pores. Particularly, the paper fiber is dispersed throughout the paper. Also, the mat fiber has relatively larger pores (pores between the fibers and the fibers) than the paper network formed of only pulp to maintain the inherent permeability of the paper.
The pores formed in the
The wrinkles on the surface of the Korean paper can form an irregular irregular network structure to absorb the energy of sound waves. The area of contact with the sound waves can be increased through the protruding portion of the wrinkles, so that it is possible to absorb various sound wave regions, preferably low sound regions, compared with the conventional paper. The irregular irregular network structure formed by the corrugations forms a protruding network structure unlike the network structure formed inside the upper limb.
Referring to FIG. 3, if the surface to which the built-in board (base panel) and the
The sound absorbing paper board of the present invention may be formed by laminating two or more wrinkled Korean paper, or alternatively, a plain paper can be laminated on a wrinkled paper as shown in FIG. Referring to FIG. 4, there is a network of protruded corrugations between the
FIG. 5 is a photograph of a sound absorbing paper board manufactured according to the present invention. Referring to FIG. 5, the sound absorbing paper board manufactured in the present invention maintains a luxurious and aesthetic design and texture of a wrinkled zoom paper, Performance can be further increased.
In addition, the present invention can include a talc powder having a size of 10 to 100 meshes, preferably 20 to 50 meshes, partially impregnated with a network structure of a Korean paper made of duck fiber and pulp and partially protruding from the surface of the paper. The talc powder may protrude at a height of 0,1 to 2 mm on the surface of the paper.
The sound absorbing paper board of the present invention can include an antibacterial and sterilizing function because it includes a textured powder in the paper, and the predetermined protruding portion is formed on the surface of the paper, so that the sound absorption efficiency of the paper can be enhanced.
The
In addition, the present invention may further include a flame retardant or flame retardant layer on the coating layer (30) or the internal board (10). Preferably, a flame retardant or a flame retardant layer is first formed on the board, . As the flame retardant and flame retardant, known water soluble phosphorus (ammonium) or inorganic flame retardants may be used.
In another aspect, the present invention relates to a method of manufacturing the absorbent article. The method of manufacturing the sound absorbing sheet includes the steps of forming wrinkles on the Korean paper, attaching the wrinkled paper on the upper surface of the board, and forming the coating layer on the paper.
The step of forming the wrinkles on the paper may be performed during the process of manufacturing the paper or after the paper is manufactured.
As an example, the step of forming corrugations on the paper comprises
Preparing a mixture by mixing the fiber and pulp, and then papermaking the mixture to provide a paper sheet; dipping the prepared paper sheet in water, rubbing the same by hand for a predetermined time, and drying the paper sheet by spreading.
The wrinkle forming step may utilize a known method of forming the zamba fur, but is not limited thereto. The wrinkle forming step may be performed by immersing the paper in a state of being immersed in water for 10 minutes or less, preferably about several minutes. In addition, the drying step may be performed by slowly drying the paper in a natural state by spreading the paper.
In the step of forming the wrinkles on the paper, the water is completely removed from the paper after the water is completely removed during the process of manufacturing the paper, and then the paper is dried for about several minutes and then dried to form wrinkles .
The Korean paper may be prepared by partially adding the pulp to 100 parts by weight of the paper fiber. For example, the pulp may be added in an amount of 10 to 60 parts by weight based on the fiber.
The method may include adding a powdery flour having a size of 10 to 100 meshes, preferably 20 to 50 meshes, in the step of mixing the dough fiber and the pulp to prepare the mixture or in the papermaking step.
The coating layer may be formed by applying a synthetic resin or a natural resin on a wrinkled paper.
In addition, the coating layer can simultaneously form a wrinkle and a coating with a coating diluent in the step of forming a wrinkle on a Korean paper. For example, after a predetermined amount of a synthetic resin or a natural resin is diluted with water, the above-mentioned paper can be immersed in the water to be soaked for several minutes.
The coating diluent may be prepared by adding the known natural resin for coating or synthetic resin in water to 50 wt% or less, preferably 30 wt% or less.
Formation of wrinkles using a coating diluent can not only reduce the number of process steps but also can evenly form a coating layer on the wrinkle surface.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. Therefore, the scope of the present invention is not limited to the above-described embodiments, but should be construed to include various embodiments within the scope of the claims and equivalents thereof.
