Description

흡음재(吸音材)란, 소리를 흡수할 목적으로 사용하는 건축재료로, 구조에 따라 다공질 흡음재와 판상(板狀) 흡음재로 구분된다. 상기 다공질 흡음재는 표면과 내부에 미세한 기포(氣泡) 또는 미세관(管) 모양의 구멍이 형성되고, 이와 같은 구멍 내부의 공기가 음파에 의해 진동하여 생긴 마찰 때문에 소리에너지가 열에너지로 변환되어 흡수된다. 그리고 상기 판상 흡음재는, 음파가 판을 진동시키면서 소리에너지를 소모함으로써 흡음 효과를 얻는다.Sound absorbing material (sound absorbing material) is a building material used for absorbing sound, and it is divided into a porous sound absorbing material and a plate sound absorbing material according to its structure. The porous sound-absorbing material has fine bubbles or fine-tube-shaped holes formed on its surface and inside, and the sound energy is converted into heat energy and absorbed due to the friction caused by the air inside the holes being vibrated by the sound waves . The plate-like sound absorbing material obtains a sound absorbing effect by consuming sound energy while the sound waves vibrate the plate.

Then, a material such as cotton or pulp is mixed with an admixture such as a binder, a flame retardant, a waterproofing material, an anti-rust material, etc., and then formed and cut into a predetermined shape and size to be used in the form of a panel.

본 발명에 의한 흡음재 및 그 제조 방법의 실시예에 의하면 다음과 같은 효과를 기대할 수 있게 된다.According to the embodiment of the sound absorbing material and the manufacturing method thereof according to the present invention, the following effects can be expected.
먼저 본 발명의 실시예는, 펄프 및 물과 혼화제(混和劑)를 기설정된 비율로 첨가하여 제조된다. 따라서 본 발명의 실시예에 의하면, 혼화재(混和材)를 사용하는 종래에 비하여 첨가되는 재료의 양이 감소됨으로써, 보다 간단하게 저렴하게 흡음재를 제조할 수 있게 된다.First, an embodiment of the present invention is produced by adding pulp, water and an admixture in predetermined proportions. Therefore, according to the embodiment of the present invention, the amount of the material to be added is reduced compared with the conventional method using the admixture, thereby making it possible to manufacture the sound absorbing material more simply and inexpensively.
또한 본 발명의 실시예의 경우에는, 종래에 비하여 높은 흡음계수를 갖는다. 따라서 본 발명의 실시예에 의하면, 보다 흡음 성능의 증가에 따른 효율적인 흡음이 이루어질 수 있게 된다. In addition, the embodiment of the present invention has a higher sound absorption coefficient than the conventional art. Therefore, according to the embodiment of the present invention, efficient sound absorption can be achieved as the sound absorption performance increases.
도 1은 본 발명에 의한 흡음재의 제조 방법의 실시예를 보인 플로우 차트.
도 2는 본 발명의 실시예에 의하여 제조된 흡음재를 보인 평면도.1 is a flowchart showing an embodiment of a method for manufacturing a sound absorbing material according to the present invention.
2 is a plan view of a sound absorbing material manufactured according to an embodiment of the present invention.
이하에서는 본 발명에 의한 흡음재의 제조 방법의 실시예를 첨부된 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, embodiments of a method of manufacturing a sound absorbing material according to the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 의한 흡음재의 제조 방법의 실시예를 보인 플로우 차트이고, 도 2는 본 발명의 실시예에 의하여 제조된 흡음재를 보인 평면도이다.FIG. 1 is a flow chart showing an embodiment of a method for manufacturing a sound absorbing material according to the present invention, and FIG. 2 is a plan view showing a sound absorbing material manufactured according to an embodiment of the present invention.
도 1 및 도 2를 참조하면, 본 실시예에 의한 흡음재는, 펄프를 주재료로 하고, 물과 함께 바인더제, 발포제, 난연제 및 유연제를 첨가하여 제조된다. 이때 상기 바인더제, 발포제, 난연제 및 유연제는, 혼화재(混和材)가 아닌 혼화제(混和劑)로써 펄프 및 물과 혼합된다. 즉, 본 실시예에서는, 상기 바인더제, 난연제 및 유연제가, 실질적으로 펄프와 물의 배합계산과 무관하게 별도로 설정된 중량비만큼 혼합된다.Referring to FIGS. 1 and 2, a sound absorbing material according to the present embodiment is produced by adding pulp as a main material and a binder, a foaming agent, a flame retardant, and a softening agent together with water. At this time, the binder, the foaming agent, the flame retardant, and the softener are mixed with pulp and water as an admixture, not as an admixture. That is, in this embodiment, the binder, the flame retardant, and the softening agent are mixed substantially at a set weight ratio regardless of the mixing ratio of pulp and water.
보다 상세하게는, 본 실시예에서는, 상기 펄프 및 물이 3:10 내지 4:10의 비율로 혼합된다. 바람직하게는, 상기 펄프 및 물은 7:23의 비율로 혼합된다. 이때 상기 물에 대한 상기 펄프의 비율이 상술한 범위 초과인 경우에는, 강도는 상대적으로 증가되지만, 유동성의 저하로 인한 상술한 첨가 재료와의 혼합에서의 단점이 발생된다. 또한 상기 물에 대한 상기 펄프의 비율이 상술한 범위 미만인 경우에는, 이와 반대의 문제점이 발생된다.More specifically, in this embodiment, the pulp and water are mixed at a ratio of 3:10 to 4:10. Preferably, the pulp and water are mixed in a ratio of 7:23. At this time, when the ratio of the pulp to the water exceeds the above-mentioned range, the strength is relatively increased, but a disadvantage in mixing with the above-mentioned additive material due to lowering of fluidity occurs. When the ratio of the pulp to the water is less than the above-mentioned range, the opposite problem arises.
한편 본 실시예에서는, 상기 바인더제, 발포제, 난연제 및 유연제가 아래의 [표 1]과 같은 비율로 첨가된다.In this embodiment, the binder, the foaming agent, the flame retardant, and the softener are added in the same ratio as shown in Table 1 below.
여기서 상기 바인더제는, 상기 펄프 및 각종 첨가 재료의 접착을 위한 접착제 역할을 한다. 그리고 상기 발포제는, 상기 흡음재의 흡음 성능의 확보를 위한 다수개의 미세 기공(氣孔)을 형성하는 역할을 한다. 상기 난연제는 내연 성능을 향상시키는 역할을 하고, 상기 유연제는 유동성의 확보를 위하여 상기 펄프 및 첨가 재료의 유연성을 증가시키는 역할을 한다.Here, the binder agent acts as an adhesive for bonding the pulp and various additive materials. The foaming agent serves to form a plurality of micropores for securing sound absorption performance of the sound absorbing material. The flame retardant plays a role in improving the internal combustion performance, and the softener plays a role of increasing the flexibility of the pulp and the additive material in order to secure fluidity.
본 실시예에서는, 상기 바인더제 및 발포제로 카복실메틸 섬유소(Carboxymethyl cellulose, CMC)가 사용된다. 상기 카복실메틸 섬유소는, 상기 펄프 100g 당 3.25~9.75g이 첨가된다. 바람직하게는, 상기 카복실메틸 섬유소가 상기 펄프 100g 당 6.50g이 첨가된다.In this embodiment, Carboxymethyl cellulose (CMC) is used as the binder and blowing agent. The carboxyl methyl cellulose is added in an amount of 3.25 to 9.75 g per 100 g of the pulp. Preferably, 6.50 g of the carboxyl methyl cellulose per 100 g of the pulp is added.
또한 본 실시예에서는, 상기 난연제가 제1 및 제2난연제를 포함한다. 상기 제1난연제로는 펜타에리스리톨(Pentaerythritol, PT)가 사용되고, 상기 제2난연제로는 폴리인산암모늄(Ammonium Phosphate, APP)이 사용된다. 상기 펜타에리스리톨은, 상기 펄프 100g 당 3.0~9.0g이 첨가되고, 상기 폴리인산암모늄은, 상기 펄프 100g 당 2.75~8.25g이 첨가된다. 다만, 상기 폴리인산암모늄은 상기 펜타에리스리톨에 비하여 상대적으로 적은 양이 첨가된다. 바람직하게는, 상기 펠타 에리스리톨은 상기 펄프 100g 당 6.00g이 첨가되고, 상기 폴리인산암모늄은, 상기 펄프 100g 당 5.50g이 첨가된다. Further, in the present embodiment, the flame retardant includes first and second flame retardants. Pentaerythritol (PT) is used as the first flame retardant, and Ammonium Phosphate (APP) is used as the second flame retardant. The pentaerythritol is added in an amount of 3.0 to 9.0 g per 100 g of the pulp, and the ammonium polyphosphate is added in an amount of 2.75 to 8.25 g per 100 g of the pulp. However, the ammonium polyphosphate is added in a relatively small amount as compared with the pentaerythritol. Preferably, the peltaerythritol is added in an amount of 6.00 g per 100 g of the pulp, and the ammonium polyphosphate is added in an amount of 5.50 g per 100 g of the pulp.
그리고 본 실시예에서는, 상기 유연제로 폴리 에틸렌 옥사이드(PolyEthylene Oxide, PEO)가 사용된다. 바람직하게는, 상기 폴리 에틸렌 옥사이드가, 상기 펄프 100g 당 0.15g이 첨가된다. In this embodiment, polyethylene terephthalate (PEO) is used as the softening agent. Preferably, 0.15 g of the polyethylene oxide is added per 100 g of the pulp.
이하에서는 본 발명에 의한 건축용 흡음재의 제조 방법에 의하여 흡음재를 제조하는 과정을 보다 상세하게 설명한다.Hereinafter, a process for manufacturing a sound absorbing material according to a method for manufacturing a sound absorbing material according to the present invention will be described in detail.
먼저 건축용 흡음재의 제작을 위해서 혼합 공정(S10)을 수행한다. 상기 혼합 공정(S10)에서는, 반죽기에서 주재료인 펄프 및 물을 상술한 비율로 혼합하고, 상술한 첨가량의 혼화제를 첨가하여 혼합한다. First, a mixing process (S10) is performed to produce a sound absorbing material for construction. In the mixing step (S10), pulp and water as main materials in a kneader are mixed at the above-mentioned ratio, and the above-mentioned additive amount of the admixture is added and mixed.
본 실시예에서는, 상기 혼합 공정(S10)이 제1 내지 제3혼합 공정(S11)(S12)(S13)을 포함한다. 상기 제1혼합 공정(S11)은, 상기 펄프 및 물이 혼합되는 공정이고, 상기 제2혼합 공정(S12)은, 혼합된 상기 펄프 및 물에 바인더제 및 발포제, 즉 카복실메틸 섬유소를 제외한 나머지 상기 혼화제가 혼합되는 공정이며, 상기 제3혼합 공정(S13)는 최종적으로 상기 바인더제 및 발포제로 사용되는 상기 카복실메틸 섬유소가 혼합되는 공정이다. In this embodiment, the mixing step (S10) includes the first to third mixing steps (S11), (S12), and (S13). Wherein the first mixing step (S11) is a step of mixing the pulp and water, and the second mixing step (S12) is a step of mixing the pulp and water mixed with the binder and the foaming agent, And the third mixing step (S13) is a step of finally mixing the carboxyl methyl cellulose used as the binder and the foaming agent.
이와 같이 상기 혼합 공정(S10)이 상기 제1 내지 제3혼합 공정으로 구성되는 것은, 보다 효율적으로 상기 펄프, 물 및 혼화제를 혼합하기 위함이다. 즉, 상기 혼화제를 상기 펄프 및 물과 함께 혼합 하는 경우에는, 종래의 혼화재에 비하여 상대적으로 소량 첨가된다. 따라서 상기 펄프 및 물과 함께 상기 혼화제가 혼합되는 경우에는, 상기 혼화제가 고르게 혼합되지 못하는 단점이 발생된다. 따라서 본 실시예에서는, 상기 펄프 및 물을 혼합한 후에 상기 혼화제를 혼합함으로써, 상술한 문제를 해결할 수 있게 된다. 또한 상기 혼화제 중 바인더제는 최종적으로 상기 펄프, 물 및 다른 혼화제 사이의 접착 기능을 수행하고, 상기 발포제는 최종적으로 미세 기공을 형성하는 역할을 하므로, 다른 혼화제의 혼합 후 최종적으로 혼합되는 것이다.Thus, the mixing step (S10) comprises the first to third mixing steps for mixing the pulp, water and the admixture more efficiently. That is, when the admixture is mixed with the pulp and water, a relatively small amount of the admixture is added as compared with the conventional admixture. Therefore, when the admixture is mixed with the pulp and the water, the admixture may not be uniformly mixed. Therefore, in the present embodiment, the above-mentioned problems can be solved by mixing the admixture after mixing the pulp and water. Also, since the binder agent of the admixture finally performs an adhesion function between the pulp, water and other admixture, and the blowing agent ultimately forms micropores, the admixture is finally mixed after mixing the other admixtures.
다음으로 상기 혼합 공정(S10)에서 혼합된 재료 및 혼화제를 소정의 형상으로 성형하는 성형 공정(S20)이 수행된다. 상기 성형 공정(S20)에서는, 예를 들면, 사출 성형기에 의하여 혼합된 재료 및 혼화제가 패널(Pannel) 형상 등으로 사출 성형될 수 있다.Next, a molding process (S20) for molding the mixed material and the admixture into a predetermined shape is performed in the mixing process (S10). In the molding step (S20), for example, the material mixed with the injection molding machine and the admixture may be injection molded into a shape of a panel (Pannel) or the like.
그리고 상기 성형 공정(S20)에서 성형된 흡음 패널 등을 이송기가 이송하는 이송 공정(S30)이 수행된다. Then, a conveying step (S30) for conveying the sound-absorbing panel or the like formed in the molding step (S20) is performed.
상기 이송 공정(S30)에서 상기 이송기에 의하여 이송된 흡음 패널은 건조 공정(S40)에서 건조기에 의하여 건조된다. 본 실시예에서는, 상기 건조 공정(S40)이 제1 및 제2건조 공정(S41)(S42)을 포함한다. 상기 제1건조 공정(S41)은 기설정된 제1건조 온도에서 기설정된 제1건조 시간동안 수행되고, 상기 제2건조 공정(S42)은 기설정된 제2건조 온도에서 기설정된 제2건조 시간동안 수행된다. 상기 제1건조 온도는 상기 제2건조 온도에 비하여 상대적으로 낮은 온도값으로 설정된다. 예를 들면, 상기 제1건조 온도는 상온, 즉 15~25℃의 온도로 설정되고, 상기 제2건조 온도는 60~70℃의 온도로 설정된다. 그리고 상기 제1건조 시간은 상기 제2건조 시간에 비하여 상대적으로 짧은 시간으로 설정된다. 예를 들면, 상기 제1건조 시간은 1시간 이내의 시간으로 설정되고, 상기 제2건조 시간은 10시간 이상의 시간으로 설정될 수 있다. 즉, 본 실시예에서는, 상대적으로 저온에서 상대적으로 짧은 시간 동안 상기 제1건조 공정(S41)을 수행한 후, 상대적으로 고온에서 상대적으로 긴 시간 동안 상기 제2건조 공정(S42)을 수행하는 것이다. 이는 상당량의 수분을 함유한 상기 흡음 패널을 곧바로 상대적으로 고온으로 건조시키는 경우에는, 상기 흡음 패널이 휘거나 상기 흡음 패널에 크랙이 형성되는 경우가 발생한다. 따라서 본 실시예에서는, 상기 흡음 패널을 최초 상온에서 1차 건조시킨 후, 어느 정도의 수분이 증발되면 고온에서 2차 건조시킨다.The sound-absorbing panel conveyed by the conveyor in the conveying step (S30) is dried by the dryer in the drying step (S40). In this embodiment, the drying step (S40) includes the first and second drying steps (S41) and (S42). The first drying step (S41) is performed for a first drying time predetermined at the first drying temperature, and the second drying step (S42) is performed during a second drying time predetermined at the second drying temperature do. The first drying temperature is set to a relatively low temperature value as compared with the second drying temperature. For example, the first drying temperature is set at room temperature, i.e., 15 to 25 ° C, and the second drying temperature is set to a temperature of 60 to 70 ° C. The first drying time is set to a relatively short time as compared with the second drying time. For example, the first drying time may be set to a time within 1 hour, and the second drying time may be set to a time of 10 hours or more. That is, in the present embodiment, the first drying step (S41) is performed at a relatively low temperature for a relatively short time, and the second drying step (S42) is performed at a relatively high temperature for a relatively long time . This is because, when the sound-absorbing panel containing a considerable amount of moisture is directly dried at a relatively high temperature, the sound-absorbing panel may be bent or a crack may be formed in the sound-absorbing panel. Therefore, in the present embodiment, the sound-absorbing panel is firstly dried at the first room temperature, and then the second panel is dried at a high temperature when a certain amount of moisture is evaporated.
마지막으로 상기 건조 공정(S40)에서 건조된 흡음 패널을 소정의 크기로 절단하는 절단 공정(S60)이 수행된다. 상기 절단 공정(S60)에서는, 도 2에 도시된 바와 같이, 상기 흡음 패널이 절단기에 의하여 실제 건축 현장에서 사용될 수 있는 크기로 절단될 것이다.Finally, a cutting step (S60) for cutting the dried sound-absorbing panel to a predetermined size is performed in the drying step (S40). In the cutting step (S60), as shown in Fig. 2, the sound-absorbing panel will be cut to a size that can be used in actual construction sites by a cutter.
이와 같이 제작되는 본 실시예에 의한 흡음 패널은, 종래의 흡음 패널에 비하여 상대적으로 효율적인 흡음 성능을 발휘할 수 있다. 아래의 [표 2]는 종래 기술에 의한 흡읍 패널과 본 실시예에 의하여 흡음 패널의 소음 주파수별 흡음 성능을 비교한 것이다.The sound-absorbing panel according to this embodiment manufactured as described above can exhibit a sound-absorbing performance that is relatively more efficient than that of the conventional sound-absorbing panel. Table 2 below compares the sound absorption performance of the sound-absorbing panels according to the conventional art and the sound-absorbing panels according to the present embodiment.
[표 2]는 23.7~25.4℃의 온도 조건 및 53.8~55.6% R.H.의 습도 조건 하에서 각 주파수별 소음에 대한 흡음 계수를 실험한 값이다. 그리고 [표 2]에서 종래 기술에 의한 흡음재는 솜을 주재료로 하고, 각종 혼화재(混和材)를 첨가하여 제작한 것이다. 따라서 [표 2]에서 확인할 수 있는 바와 같이, 본 실시예에 의한 흡음재의 경우가 종래 기술에 의한 흡음재에 비하여 월등한 흡음 성능을 갖는다고 할 수 있다.[Table 2] shows the absorption coefficient for noise of each frequency under the temperature condition of 23.7 ~ 25.4 ℃ and the humidity condition of 53.8 ~ 55.6% R.H. In Table 2, the sound absorber according to the prior art is made by adding cotton as a main material and various admixtures. Therefore, as shown in [Table 2], it can be said that the sound absorbing material according to the present embodiment has a superior sound absorbing performance as compared with the sound absorbing material according to the prior art.
