본 발명은 흡음재용 외장시트, 그의 제조방법 및 흡음형 방음패널에 관한 것이다.
The present invention relates to an outer sheet for a sound absorbing material, a method for manufacturing the same, and a sound absorbing soundproof panel.

최근 생활수준 향상과 더불어 쾌적한 문화생활이 점차 요구되면서 건축 음향 설계의 중요성이 대두되고 있다. 이에 실내에서 발생되는 각종 소음을 흡음시켜 실내의 소음을 억제시키도록 흡음성을 갖는 방음패널이 건축 내장재용으로서 다양하게 사용되고 있다. Recently, with the improvement of living standards and the demand for comfortable cultural life, the importance of architectural sound design is emerging. In order to absorb various noises generated in the room and to suppress the noise in the room, soundproof panels having sound absorbing properties have been variously used for building interior materials.

흡음재는 그 특성상 통기성 및 흡음력을 갖추어야 하고, 이를 위해서는 내부에 많은 기공이 필요하다. 또한 통기성이 우수해야 흡음 효과가 극대화 될 수 있다. The sound absorbing material should have breathability and sound absorbing power due to its characteristics, and for this purpose, many pores are required inside. In addition, excellent ventilation can maximize the sound absorption effect.

그러나, 일반적으로 내장재로서 사용되기 위해서는 흡음재의 외면에 표면장식재를 시공해야 하고, 이 경우 흡음재의 방음 또는 방염 성능이 상당히 상실되어 버린다는 문제가 있다. 예를 들어, 외면에 섬유조직의 직물로 커버하는 경우 표면 외관이 단일화 되며, 공공장소에 주로 설치되는 흡음재의 특성상 방염 성능을 요구하게 되는데 이 경우 흡음 성능이 떨어지게 된다.
In general, however, in order to be used as an interior material, a surface decorative material must be installed on the outer surface of the sound absorbing material, and in this case, there is a problem that the soundproofing or flameproofing performance of the sound absorbing material is considerably lost. For example, if the outer surface is covered with a textile fabric, the surface appearance is unified, and the flame retardant performance is required due to the characteristics of the sound absorbing material mainly installed in a public place.

본 발명은 흡음재 외부의 섬유조직을 대체하여 다양한 디자인 표현이 가능하며, 또한 디자인의 입체화가 가능한 흡음재용 외장시트를 제공하고자 한다. 또한, 방염성능과 흡음력 및 통기성을 고루 갖추고 있는 흡음재용 외장시트를 제공하고자 한다.

Advantages and features of the present invention and methods of performing the same will be understood more readily by reference to the following detailed description of the embodiments and the accompanying drawings. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

흡음재용 외장시트Sound absorbing material exterior sheet

도 1에는 본 발명의 일 실시예에 따른 흡음재용 외장시트의 단면도가 모식적으로 도시되어 있다. 1 is a cross-sectional view schematically showing a sound absorbing material exterior sheet according to an embodiment of the present invention.

도 1을 참조하면, 흡음재용 외장시트(100)는 유리섬유 페이퍼로 된 기재(110)와, 상기 기재 상에 형성된 입체 무늬(120)로 이루어진다. Referring to FIG. 1, the sound absorbing material exterior sheet 100 includes a substrate 110 made of glass fiber paper, and a three-dimensional pattern 120 formed on the substrate.

상기 유리섬유 페이퍼(110)는 다공성 구조로서 흡음재의 흡음 성능을 유지시킬 수 있다는 장점이 있다. 유리섬유 페이퍼(110)는 실리콘을 주성분으로 하는 무기질 방사사로 직조된 것으로서, 유리 섬유(glass wool), 유리 페이퍼(glass paper), 유리섬유 시트(glass fiber sheet)를 모두 포함하고, 난연성을 갖고 있어서 흡음재에 방염기능을 부여할 수 있다. 상기 유리 페이퍼(Glass Paper)는 유리 섬유(Glass Fiber)와 펄프가 혼합되어 종이 상태로 만들어진 것으로서, 시판 제품의 예로는 한국카본의 GP-50G (평량은 50g/m2 기준이며, 필요에 따라 조정가능) 등을 들 수 있으나 이에 제한되지 않는다. The glass fiber paper 110 has an advantage that it can maintain the sound absorption performance of the sound absorbing material as a porous structure. The glass fiber paper 110 is woven from an inorganic spinning yarn mainly composed of silicon, and includes all of glass wool, glass paper, and glass fiber sheet, and has flame retardancy. Flame retardant function can be imparted to the sound absorbing material. The glass paper (Glass Paper) is made of glass fiber (Plasa Fiber) and pulp in the form of paper, examples of commercially available products are based on GP-50G (Basic weight is 50g / m 2 basis of the carbon in Korea, adjusted as needed Possible) and the like, but is not limited thereto.

상기 입체 무늬(120)는 PVC 등 열에 의해 가교반응이 일어나는 열가소성 소재로 이루어질 수 있고, 발포체로 이루어져 있다. 따라서, 입체 무늬에 부피감을 부여할 뿐만 아니라 다공성 구조로서 흡음재의 흡음 성능을 보조한다. The three-dimensional pattern 120 may be made of a thermoplastic material that crosslinking reaction occurs by heat such as PVC, it is made of a foam. Therefore, it not only imparts volume to the three-dimensional pattern, but also assists the sound absorbing performance of the sound absorbing material as a porous structure.

경우에 따라 상기 기재(110)의 표면에 표면 코팅층(115)을 형성할 수 있고, 이 경우 상기 표면 코팅층(115) 상에 입체무늬(120)가 형성된다. 상기 표면 코팅층(115)은 기재(110)에 색상을 부여하거나 평면무늬를 부여하기 위한 것일 수 있다. In some cases, the surface coating layer 115 may be formed on the surface of the substrate 110. In this case, the three-dimensional pattern 120 may be formed on the surface coating layer 115. The surface coating layer 115 may be to give a color to the substrate 110 or to give a flat pattern.

일 예에서, 상기 입체무늬(120)의 외면에 공기정화층(130)이 형성될 수 있다. 상기 공기정화층(130)은 예를 들어 배기 가스를 흡수하는 제올라이트 또는 이산화티탄 등의 광촉매(Photocatalyst)로 이루어질 수 있다. 이러한 광촉매는 공기 유해물질이 빛에 의해 분해되도록 유도하거나 자외선으로 산화시켜 제거함으로써 공기정화기능을 부여할 수 있고, 경우에 따라서는 방염 성능이 부가될 수도 있다. 예를 들어, 이산화티탄(TiO2) 분말은 자동차 배기가스 중 SOX, NOX를 흡착시킴으로서 소음흡수는 물론 자동차 배기가스 정화기능을 발휘할 수 있다. In one example, the air purification layer 130 may be formed on the outer surface of the three-dimensional pattern 120. The air purification layer 130 may be formed of, for example, a photocatalyst such as zeolite or titanium dioxide that absorbs exhaust gas. Such a photocatalyst may impart an air purification function by inducing the harmful air to be decomposed by light or by oxidizing and removing it by ultraviolet rays, and in some cases, flame retardant performance may be added. For example, titanium dioxide (TiO 2) powder was sikimeuroseo adsorption of the vehicle exhaust SO X, NO X absorbing noise may as well exert a function of purifying automobile exhaust gas.

본 발명의 예시에 따른 흡음재용 외장시트(100)는 입체 무늬(120)가 표면에 형성되어 있어서 흡음재의 표면에 다양한 미감을 부여할 수 있을 뿐만 아니라 흡음재의 기능을 유지하면서 방염 성능을 확보할 수 있다는 장점이 있다.
In the sound absorbing material exterior sheet 100 according to an exemplary embodiment of the present invention, since the three-dimensional pattern 120 is formed on the surface, the sound absorbing material may not only provide various aesthetics to the surface of the sound absorbing material, but also ensure flameproof performance while maintaining the function of the sound absorbing material. There is an advantage.

본 발명에 따른 흡음형 방음패널은 외장시트가 다공성 구조를 유지하고 있어서 흡음재 자체의 음파 흡수 효율을 극대화할 수 있다. 따라서, 흡음 및 방음 효과가 우수하고, 외면에 입체 무늬가 형성되어 있어서 외관이 미려하고 인테리어 효과를 발휘할 수 있다. 또한, 제조 공정이 간단하고 용이하여 생산비용을 줄일 수 있다.
In the sound absorbing soundproof panel according to the present invention, the exterior sheet maintains a porous structure, thereby maximizing the sound wave absorption efficiency of the sound absorbing material itself. Therefore, it is excellent in sound absorption and soundproofing effects, and the three-dimensional pattern is formed in the outer surface, and a beautiful appearance can exhibit an interior effect. In addition, the manufacturing process is simple and easy to reduce the production cost.

본 발명이 속한 분야에서 통상의 지식을 가진 자라면 상기 내용을 바탕으로 본 발명의 범주 내에서 다양한 응용 및 변형을 행하는 것이 가능할 것이다. Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
