Description

결합부를 포함하는 난연 처리된 방음재{NONFLAMMABLE SOUND PROOF MATERIAL INCLUDING CLIP}Non-flame retardant soundproof material comprising a joining portion {NONFLAMMABLE SOUND PROOF MATERIAL INCLUDING CLIP}

본 발명은 방음재에 관한 것으로, 더욱 상세하게는 결합부를 포함하는 난연 처리된 방음재에 관한 것이다. The present invention relates to a soundproofing material, and more particularly to a flame-retardant treated soundproofing material including a coupling portion.

종래에 일반적으로 알려지고 있는 내장재로는 목재로 구성되는 합판이나 합성수지로 구성되는 패널이 있고, 내연성이나 난연성 등의 재질로서 비교적 화재에 안전하다는 석고보드나 석면보드 등이 알려지고 있으나, 목재합판이나 합성수지제 판넬로 구성되는 내장재는 내열성이 떨어지고 인화성이 강하여 화재에 쉽게 소실 될 뿐만 아니라, 특히 합성수지의 경우 유독가스로 인한 인명피해와 공해를 야기시키게 되고, 폐기됐을 때도 합성수지는 쉽게 부식되지 않아서 환경오염의 원인이 되기도 한다. Conventionally known interior materials include plywood made of wood or panels made of synthetic resin, and gypsum board or asbestos board, which are relatively safe to fire as materials such as flame resistance and flame retardancy, are known. Interior materials composed of synthetic resin panels are not easily heat-resistant due to low heat resistance and high flammability, and in particular, synthetic resins cause human injury and pollution due to toxic gases. It can also cause.

또한 비교적 화재에 안전하다는 석고보드나 석면보드는 전체적으로 내구성이 취약하여 운반과 시공 과정에서 파손 등에 의한 손실이 크고, 중량이 무거워서 운반이나 시공에 어려움이 있게 되고 환경오염은 물론 인체에 유해하여 폐기 처리 절차가 용이하지 못함으로 폐기하는데 많은 비용이 소요되는 문제점이 있게 되는 것이다.In addition, gypsum board or asbestos board, which is relatively safe for fire, is poor in overall durability, so there is a large loss due to breakage during transportation and construction, and heavy weight makes transportation or construction difficult, environmental pollution and harmful to human body. Since the procedure is not easy, there is a problem that it is expensive to dispose of.

도 1 내지 도 4를 참조하면, 본 발명에 따른 난연 처리된 방음재(100)는 복수 개의 기본판(10) 및 결합부(20)로 구성된다.1 to 4, the flame-retardant soundproofing material 100 according to the present invention is composed of a plurality of base plate 10 and the coupling portion 20.

기본판(10)은 천연 재료의 난연 약제로 난연 처리된다. 기본판(10)은 펄프 몰드로 제조된다. 펄프 몰드란, 폐지(waste paper) 또는 천연 펄프(virgin pulp)를 물에 해리시킨 펄프용액을 다양한 형태의 금형(mold)을 제작하여 진공 성형한 후, 건조하여 만든 성형품을 말하는 것으로, 사용하는 원료의 특성상 인체 및 환경에 무해하고, 전량 재활용이 가능함은 물론, 소각 또는 매립 시에도 환경 유해 물질을 배출하지 않는 친환경 물질이다.The base plate 10 is flame retarded with a flame retardant agent of natural materials. The base plate 10 is made of pulp mold. Pulp mold refers to a molded product made by drying a pulp solution in which waste paper or natural pulp is dissociated in water, vacuum forming a mold of various forms, and drying the mold. Due to its nature, it is harmless to humans and the environment, and can be recycled entirely, and it is an environmentally friendly material that does not emit environmentally harmful substances when incinerated or landfilled.

기본판(10)은 상부 및 하부로 돌출되도록 형성되는 다각형의 복수 개의 제1 돌출부(11)를 포함한다. 본 실시예에서는 제1 돌출부(11)가 허니콤 형태로서, 8각형인 것을 예로 들어 설명하지만, 이러한 형태에 한정되는 것은 아니다.The base plate 10 includes a plurality of polygonal first protrusions 11 formed to protrude upward and downward. In the present embodiment, the first protrusion 11 has a honeycomb shape and is described as an example of an octagon, but the present invention is not limited thereto.

결합부(20)는 기본판(10)과 마찬가지로 천연 재료의 난연 약제로 난연 처리되고, 펄프 몰드로 제조된다. 결합부(20)는 제2 돌출부(21)와 이음부(25)를 포함한다. 제2 돌출부(21)는 결합부(20)의 하부로 돌출되도록 다각형으로 형성된다. 본 실시예에서는 제2 돌출부(21)가 허니콤 형태로서, 8각형인 것을 예로 들어 설명하지만, 이러한 형태에 한정되는 것은 아니다. 이음부(25)는 결합부(20)의 상부면에서 개구된 제2 돌출부(21)의 상부를 지나가도록 형성된다.Like the base plate 10, the coupling portion 20 is flame-retardant with a flame retardant agent of a natural material, it is made of a pulp mold. The coupling part 20 includes a second protrusion 21 and a joint 25. The second protrusion 21 is formed in a polygonal shape so as to protrude downward from the coupling portion 20. In the present embodiment, the second protruding portion 21 has a honeycomb shape and is described as an example of an octagon, but the present invention is not limited to this embodiment. The joint part 25 is formed to pass through the upper part of the second protrusion 21 opened at the upper surface of the coupling part 20.

결합부(20)는 십자 형태인 것을 예로 들어 설명하지만, 이러한 형태에 한정되는 것은 아니다. 결합부(20)는 기본판(10)들 사이, 네 개의 기본판(10)이 결합부(20)의 네 모서리에 각각 결합되고, 이들의 결합은 접착제를 통해 이루어질 수 있다. 결합부(20)를 통해 기본판(10)들이 용이하게 결합될 수 있으므로, 다양한 크기의 방음재(100)를 제조할 수 있다.Coupling portion 20 is described in the form of a cross, for example, but is not limited to this form. Coupling portion 20 between the base plate 10, the four base plate 10 is coupled to each of the four corners of the coupling portion 20, these couplings may be made through an adhesive. Since the base plate 10 can be easily coupled through the coupling portion 20, it is possible to manufacture the soundproof material 100 of various sizes.

본 실시예에 따른 난연 처리된 방음재(100)는 도 4에 도시된 바와 같이, 건축물 내부 벽체 또는 파티션의 내부에 삽입되어 사용될 수 있다. 본 실시예에 따른 난연 처리된 방음재(100)는 그 두께가 얇으면서도 난연성, 흡음성, 내구성, 및 보온성이 우수한 효과가 있다.As shown in FIG. 4, the flame-retardant soundproofing material 100 according to the present exemplary embodiment may be inserted into an interior wall or partition of a building. The flame-retardant soundproofing material 100 according to the present embodiment has an effect of excellent flame retardancy, sound absorption, durability, and thermal insulation while having a thin thickness.

이하에서는, 본 실싱에 따른 난연 처리된 방음재(100)의 난연 처리 방법에 대하여 설명한다. 도 5는 본 발명에 따른 난연 처리된 방음재의 기본판과 결합부의 제조 방법을 나타낸 블록도이다.Hereinafter, the flame-retardant treatment method of the flame-retardant sound-proof material 100 according to the present sealing will be described. Figure 5 is a block diagram showing a manufacturing method of the base plate and the coupling portion of the flame-retardant soundproofing material according to the present invention.

도 5를 참조하면, 먼저 원료 및 약물을 파쇄기에 투입하여 파쇄한다(S501). 원료는 신문폐지 및 백상지 고지 등의 셀룰로오스계 천연재료를 이용한다.Referring to FIG. 5, first, raw materials and drugs are put into a crusher and crushed (S501). The raw material uses cellulose-based natural materials such as newspaper waste paper and wood waste paper waste paper.

이어서, 4% 농도의 원료를 저장 탱크로 이송한다(S503). 본 과정은 원료와 약품의 반응 및 원료의 저장을 위한 목적이다.Subsequently, the raw material having a concentration of 4% is transferred to the storage tank (S503). This process is for the reaction of raw materials and chemicals and the storage of raw materials.

다음으로, 사각 탱크로 이송하여 물과 원료의 농도를 조절하고(S505), 성형 탱크에서 진공을 이용하여 제품을 성형한다(S507). 이 때, 성형은 메쉬 금형에서 0.5~0.8기압으로 진행된다.Next, the concentration of water and the raw material is controlled by transferring to the square tank (S505), and the product is molded using a vacuum in the molding tank (S507). At this time, molding is carried out at 0.5 to 0.8 atm in the mesh mold.

이어서, 제1 압착 건조를 수행한다(S509). 이 때, 250~300도의 온도에서 5 톤 이상의 압력으로 압착 건조를 수행한다. Next, the first compression drying is performed (S509). At this time, the compression drying is carried out at a pressure of 5 tons or more at a temperature of 250 ~ 300 degrees.

다음으로, 제2 압착 건조를 수행한다(S511). 이 때, 200~280도의 온도에서 5 톤 이상의 압력으로 압착 건조를 수행한다.Next, second compression drying is performed (S511). At this time, compression drying is performed at a pressure of 5 tons or more at a temperature of 200 to 280 degrees.

이어서, 제3 압착 건조를 수행한다(S513). 이 때, 250~300도의 온도에서 7 톤 이상의 압력으로 압착 건조를 수행한다.Then, the third compression drying is performed (S513). At this time, the compression drying is carried out at a pressure of 7 tons or more at a temperature of 250 ~ 300 degrees.

이와 같이, 다단 압착 이후에, 난연 처리를 수행한다(S515). 이 때, 난연 처리는 난연액 스프레이로 코팅하거나, 난연액에 침수하는 것으로 수행될 수 있다. 그리고 난연액은 천연재료이다.In this way, after the multi-stage compression, flame-retardant treatment is performed (S515). At this time, the flame retardant treatment may be performed by coating with a flame retardant spray or by immersion in the flame retardant. And flame retardant is a natural material.

다음으로, 기본판(10)과 결합부(20)를 원하는 형태로 조립하고(S517), 공압으로 압착하여 완성한다(S519). 이 때, 압력은 최소 5 톤 이상인 것이 바람직하다.Next, the base plate 10 and the coupling portion 20 are assembled into a desired shape (S517), and is compressed to complete by pneumatic (S519). At this time, the pressure is preferably at least 5 tons or more.

한편, 본 실시예에 따른 결합부를 포함하는 난연 처리된 방음재는 전술한 형태에 한정되지 않고, 본 발명의 기술적 중심 사상을 벗어나지 않는 범위 내에서 다양하게 변형 실시될 수 있다. 이는 본원발명이 속하는 기술 분야에 종사하는 자라면 쉽게 알 수 있을 것이다.On the other hand, the flame-retardant soundproofing material including the coupling portion according to the present embodiment is not limited to the above-described form, it can be variously modified within the scope not departing from the technical spirit of the present invention. This will be readily apparent to those skilled in the art.
