이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 흡음재 제조방법을 나타낸 공정도이고, 도 2는 본 발명에 따른 흡음재 제조방법의 각 공정을 나타낸 것으로, 도 2a는 격자체 준비 단계를 나타낸 사시도이고, 도 2b는 흡음재 성형단계를 나타낸 사시도이다. 1 is a process chart showing a sound absorbing material manufacturing method according to the present invention, Figure 2 shows each step of the sound absorbing material manufacturing method according to the present invention, Figure 2a is a perspective view showing a lattice preparation step, Figure 2b is a sound absorbing material forming step Is a perspective view.

이에 본 발명의 흡음재 제조방법은, 먼저, 제지슬러지를 건조시켜 슬러그 입 자를 제조하는 단계(10)를 진행한다. In the sound absorbing material manufacturing method of the present invention, first, the step of drying the paper sludge to prepare a slug particles (10).

상기 제지슬러지는 폐종이를 재생하는 공장에서 발생되는 것으로, 이러한 제지슬러지는 종이, 석분, 섬유질 등으로 이루어진다. 이와 같은 제지슬러지는 상온에서 자연건조시킴에 따라 고형화되는데, 이를 분쇄하여 제조되는 것이 슬러그 입자이다.The paper sludge is generated in a factory for recycling waste paper, and the paper sludge is made of paper, stone powder, fiber, or the like. Such paper sludge is solidified by natural drying at room temperature, and is produced by pulverizing it.

다음, 일정한 폭과 길이 및 높이를 가지며 상,하가 개방된 다수의 격자부(21)가 사방으로 연속되게 형성된 격자체(2)를 준비하는 단계(20)를 진행한다.Next, a step 20 of preparing a grating body 2 having a predetermined width, length, and height and having a plurality of grating parts 21 open up and down in succession in all directions is performed.

즉 상기 격자체(2)는, 도 2a에 도시된 바와 같이, 각 격자부(21)를 구성하는 다수의 수직판(22)이 상호 연결되어 일체로 구성되는 것으로, 도면에 도시된 바와 같이 격자부가 사각형으로 구성될 수 있고, 도면에는 미도시 되었으나 각 격자부가 육각형 등의 다각형으로 형성될 수도 있는 것이다. That is, as shown in FIG. 2A, the grating body 2 includes a plurality of vertical plates 22 constituting each grating part 21, which are integrally connected to each other, as shown in the drawing. Additional squares may be configured, and although not shown in the drawing, each grid portion may be formed of a polygon such as a hexagon.

그리고 상기 격자체(2)의 양측폭과 전,후방 길이 및 높이는, 최종 제작되는 흡음재(1)의 크기와 동일하게 구성되는 것으로, 흡음재(1)의 규격에 따라 상기 격자체(2)의 양측폭과 전,후방 길이 및 높이가 결정되는 것이다.In addition, both side widths, front and rear lengths, and heights of the grating body 2 are configured to be the same as the size of the final sound absorbing material 1, and both sides of the grating body 2 according to the specification of the sound absorbing material 1. The width and the front and rear lengths and heights are determined.

다음, 상기 슬러그 입자에 바인더를 혼합하여 재료(3)를 준비하는 단계(30)를 진행한다.Next, a step 30 of preparing a material 3 by mixing a binder with the slug particles is performed.

여기서 상기 바인더는 물, 시멘트, 황토 등 슬러그 입자 및 격자체(2)와의 결합이 가능한 공지의 바인더를 단독으로 사용할 수도 있으나, 본 발명에서는 시멘트와 황토의 혼합물로 구성된 바인더를 사용하는 것이 보다 바람직하다. Here, the binder may be a known binder capable of bonding with slug particles such as water, cement, loess, and the lattice body 2 alone, but in the present invention, it is more preferable to use a binder composed of a mixture of cement and loess. .

상기 시멘트는 슬러그 입자에 포함된 석분이나 섬유질과의 결합력이 우수하 여 바인더로 사용시 결합력 증진에 도움을 주고, 황토의 경우에는 원적외선이 방출되는 물질이기 때문에 살균등의 효능이 있어 바람직하게 사용될 수 있다. 따라서 상기 바인더는 시멘트화 분말상태의 황토를 혼합한 뒤 물과 배합하여 사용하는 것이 바람직하다. The cement is excellent in the bonding strength with the stone powder or fiber contained in the slug particles to help improve the bonding strength when used as a binder, in the case of loess because it is a material that emits far-infrared rays can be preferably used. Therefore, the binder is preferably used in combination with water after mixing the cemented powder loess.

최종적으로, 상기 슬러그 입자에 바인더의 혼합물로 이루어진 재료(3)를 격자체(2)의 격자부(21)들에 채운 후 자연 건조시켜 흡음재(1)을 성형하는 단계(40)를 진행함으로써 흡음재를 완성하는 것이다. Finally, the material 3 made of a mixture of binders in the slug particles is filled in the lattice portions 21 of the lattice 2 and then naturally dried to form the sound absorbing material 1 to proceed to step 40. To complete.

따라서, 상기 격자체(2)를 규격화시킴에 따라서 절단 공정이 없이도 규격화된 흡음재를 제조할 수 있는 것이다. 그러므로, 별도의 절단공정의 진행으로 인하여 발생되는 인력과 시간의 낭비를 방지할 수 있는 장점을 가지는 것이다. Therefore, by standardizing the lattice 2, it is possible to manufacture a standardized sound absorbing material without a cutting process. Therefore, it has the advantage of preventing the waste of manpower and time generated due to the progress of a separate cutting process.

또 석분이 함유된 제지슬러지를 이용함으로써, 시멘트와 슬러그 입자의 결착력을 향상시켜 강도를 높이고, 석분으로 인하여 불에 타지 않는 난연성을 향상시킬 수 있는 장점을 가지는 것이다. In addition, by using the papermaking sludge containing stone powder, it is possible to improve the binding strength of the cement and slug particles to increase the strength, and to improve the flame retardancy that is not burned by the stone powder.

또한 상기 격자체(2)는 종이로 구성되는 것이 보다 바람직하다. 이와 같이 상기 격자체(2)가 종이로 구성되면 슬러그 입자에 혼합된 바인더가 종이에 직접적으로 부착됨에 따라 흡음재의 전체적인 강도를 향상시킬 수 있는 장점을 가지는 것이다.In addition, the lattice 2 is more preferably made of paper. As such, when the lattice 2 is made of paper, the binder mixed in the slug particles is directly attached to the paper, thereby having the advantage of improving the overall strength of the sound absorbing material.

한편, 상기 재료 준비단계(30)에서는, 폐EVA를 수집 분쇄하여 얻어진 폐EVA 입자를 더 혼합할 수도 있는 것이다. On the other hand, in the material preparation step 30, the waste EVA particles obtained by collecting and grinding waste EVA may be further mixed.

즉 폐EVA를 수집 분쇄하여 폐EVA입자를 제조할 경우에는, 폐EVA를 수집하여 분쇄기에 투입하는 과정을 통해, 10mm이하의 작은 입자로 폐EVA를 제조하는 것이다. That is, in the case of producing waste EVA particles by collecting and grinding waste EVA, the waste EVA is collected and put into a grinder to produce waste EVA with small particles of 10 mm or less.

이러한 폐EVA입자는 우수한 진동흡수성을 갖고 있어 상기 폐EVA입자가 포함된 재료로 제조된 흡음재는 충격 등에 의한 진동흡수성이 향상되어 흡음효과가 상승될 수 있고, 충격흡수력이 우수하여 바닥용 흡음재로도 적합하게 사용가능하다.Such waste EVA particles have excellent vibration absorption, so that the sound absorbing material made of the material containing the waste EVA particles can improve the vibration absorption by impact, etc., and the sound absorption effect can be increased. It can be used suitably.

도 3은 본 발명에 따른 격자체의 상부를 긁어내는 과정을 나타낸 사시도로서, 상기 재료(3)를 격자부(21)들에 채운 후에는, 격자체의 상부에 돌출되는 재료(3)를 긁어 제거하는 과정을 더 진행할 수도 있는 것이다. 3 is a perspective view showing a process of scraping the upper part of the lattice body according to the present invention. After filling the lattice part 21 with the material 3, the material 3 protruding from the upper part of the lattice body is scraped off. You can also proceed further with the removal.

따라서, 상기 재료(3)가 채워져 고형화된 재료(3)와 격자체(2)를 통해 흡음 효과를 향상시킬 수 있는 것이다. 즉 재료(3)가 채워진 격자체를 통해 층간 충격소음을 줄이는데 큰 효과를 얻을 수 있는 장점을 가지는 것이다. Therefore, the sound absorption effect can be improved through the material 3 and the solidified material 3 and the lattice 2 which were filled. That is, it has the advantage that a great effect can be obtained in reducing the inter-layer impact noise through the lattice filled with the material (3).

다시 말해 상기 격자체(2)에는 사방으로 연속되는 격자부(21)가 구비되어 있음에 따라서, 각각의 격자부(21)에서는 재료로 유입되는 소음을 각 격자부(21)를 구성하는 수직판(22)에서 재차 유입받아 소음을 상쇄시킴으로써, 소음의 소진 효과를 최대로 향상시킬 수 있는 장점을 가지는 것이다. In other words, the grid 2 is provided with a grid portion 21 continuous in all directions, each of the grid portion 21 is a vertical plate constituting the grid portion 21 to the noise flowing into the material By re-introducing the noise received at (22) again, it has the advantage of maximizing the exhaustion effect of the noise.

또한, 상기 격자체(2)를 구성하는 각각의 격자부를 통해 압축에 대한 강도를 보강함으로써 층간 소음재로 사용할 경우에 충분한 강도를 유지할 수 있는 장점도 있는 것이다. In addition, by reinforcing the strength against compression through each of the lattice portion constituting the lattice 2, there is also an advantage that can maintain sufficient strength when used as an interlayer noise material.

즉 상기 격자체(2)에 구비된 각각의 격자부(21)는 둘레를 감싸는 수직판(22)을 포함하는 것으로, 각각의 수직판(22)은 압축에 대하여 강한 내구성을 가지게 된다. That is, each grid portion 21 provided in the grid 2 includes a vertical plate 22 surrounding the circumference, each vertical plate 22 has a strong durability against compression.

그러므로 격자체(2)가 포함되는 본 발명의 흡음재(1)을 바닥에 시공할 경우 에는, 흡음재(1)의 상부에 콘크리트를 타설하더라도 흠음판(1)의 두께가 줄어드는 현상을 방지할 수 있는 것이다. 따라서 본 발명에 따른 흡음재(1)은 압축에 대한 충분한 강도를 가지게 됨에 따라 바닥에 시공되는 흡음재(1)으로 사용하기가 적합한 장점도 가지는 것이다. Therefore, when the sound absorbing material 1 of the present invention including the lattice 2 is installed on the floor, even if concrete is poured on the upper part of the sound absorbing material 1, the phenomenon of reducing the thickness of the flaw plate 1 can be prevented. will be. Therefore, the sound absorbing material 1 according to the present invention also has an advantage that it is suitable for use as the sound absorbing material 1 to be installed on the floor as it has sufficient strength for compression.
