Description

가전제품용 흡음재 제조장치{APPARTUS FOR MANUFACTURING SOUND ABSORBING MATERIAL OF HOME APPLIANCE}Sound-absorbing material manufacturing equipment for home appliances {APPARTUS FOR MANUFACTURING SOUND ABSORBING MATERIAL OF HOME APPLIANCE}

본 발명은 유지력이 향상된 흡음재를 생산할 수 있는 구조가 개선된 가전제품용 흡음재 제조장치에 관한 것이다.The present invention relates to an apparatus for manufacturing a sound absorbing material for home appliances with an improved structure capable of producing a sound absorbing material with improved holding power.

흡음재는 소음과 진동을 차단하기 위한 목적으로 사용되며, 건축분야, 운송수단, 또는 가전제품에 내장되어 널리 사용되고 있으며, 예를 들어 건조기 또는 세탁장치와 같은 가전제품에도 흡음재가 내부에 부착되고 있다.The sound-absorbing material is used for the purpose of blocking noise and vibration, and is widely used in the field of construction, transportation, or home appliances. For example, the sound-absorbing material is attached to the inside of home appliances such as dryers or laundry machines.

이러한 흡음재는 소음 및 진동을 효과적으로 감소시킬 수 있는 소재가 개발되고 있으며, 일례로 대한민국 등록특허 제10-1375442호(발명의 명칭: 엔진 커버용 흡음재 및 그 제조방법)은 PET-FELT 소재의 흡음재를 니들펀칭을 통해 제조하는 기술적 사상을 게재하고 있다.Materials that can effectively reduce noise and vibration are being developed for such sound-absorbing materials. For example, Korean Patent No. 10-1375442 (name of the invention: sound-absorbing material for engine cover and its manufacturing method) is a sound-absorbing material made of PET-FELT. It publishes the technical idea of manufacturing through needle punching.

여기서, PET-FELT 소재의 흡음재는 조직이 아주 작은 털실들을 뭉쳐서 니들펀칭을 이용하여 제조되기 때문에 매우 복잡한 경로의 공극을 형성하여 흡음성이 매우 우수하게 구현될 수 있다.Here, the sound-absorbing material made of PET-FELT material is manufactured by using needle punching by agglomeration of very small yarns, so it can be implemented with excellent sound-absorbing property by forming pores of a very complex path.

가전제품 내부에 흡음재를 부착하기 위해서는 흡음재의 일면에 점착제가 도포되는데, 가전제품 제조사는 가전제품 내부에 부착되는 흡음재가 얼마만큼의 유지력을 가지는지 테스트를 하고 있다.In order to attach the sound absorbing material to the inside of a home appliance, an adhesive is applied to one side of the sound absorbing material, and home appliance manufacturers are testing how much retention power the sound absorbing material attached to the interior of the home appliance has.

예를 들어, 흡음재의 유지력 테스트는 1) 고정된 STS 304 시편에 흡음재를 25mm×25mm의 면적이 접하도록 2kg/㎠의 힘으로 부착하고 50분이 경과한 후, 2) 40℃의 환경에서 흡음재의 하단에 1kg의 추를 매달고 1시간 경과 후 시편에서 떨어진 거리를 측정하여 유지력을 산출할 수 있다.For example, the retention test of the sound-absorbing material is: 1) Attach the sound-absorbing material to the fixed STS 304 specimen with a force of 2 kg/㎠ so that the area of 25 mm × 25 mm is in contact, and after 50 minutes have elapsed, 2) the sound-absorbing material is The holding force can be calculated by hanging a 1 kg weight at the bottom and measuring the distance away from the specimen after 1 hour.

그러나, 이러한 유지력 테스트 결과, 종래의 PET-FELT 소재의 흡음재는 털실과 같은 표면층 조직의 특성상 유지력이 매우 약한 문제가 있다.However, as a result of this holding power test, the conventional sound absorbing material made of PET-FELT has a very weak holding power due to the characteristics of the surface layer structure such as wool.

즉, 종래의 PET-FELT 소재의 흡음재는 표면층이 비방향성을 가진 매우 작은 털실 구조로서 점착제와 흡음재의 상호간 결합력이 매우 약하기 때문에 가전제품의 사용에 따른 진동에 의해 흡음재가 가전제품에서 종종 떨어지는 문제가 발생할 수 있다.In other words, the conventional sound absorbing material made of PET-FELT material has a very small yarn structure with a non-directional surface layer, and the bonding force between the adhesive and the sound absorbing material is very weak. Can occur.

다만, 이하에 기술될 발명은 본 발명의 실시예를 설명하기 위한 것일 뿐 본 발명의 권리범위를 한정하기 위한 것은 아니며, 명세서 전반에 걸쳐서 동일하게 사용된 참조번호들은 동일한 구성요소들을 나타낸다.However, the invention to be described below is only for describing an embodiment of the present invention and not for limiting the scope of the present invention, and reference numerals used identically throughout the specification represent the same elements.

도 1은 본 발명의 실시예에 따른 가전제품용 흡음재 제조장치에 의해 제조된 흡음재를 개략적으로 도시한 도면이다.1 is a view schematically showing a sound-absorbing material manufactured by a sound-absorbing material manufacturing apparatus for home appliances according to an embodiment of the present invention.

도 1을 참조하면, 가전제품용 흡음재(10)는 이형지(20)가 일면에 부착되어 있을 수 있며, 상기 흡음재(10)의 일면(대향면)에는 상기 이형지(20)를 상기 흡음재(10)에서 때어내었을 때 보이는 점착면(30)이 형성될 수 있다.Referring to FIG. 1, the sound absorbing material 10 for home appliances may have a release paper 20 attached to one side thereof, and the release paper 20 is placed on one side (opposite side) of the sound absorbing material 10. The adhesive surface 30 visible when it is removed from may be formed.

상기 이형지(20)에는 실리콘이 도포될 수 있으며, 이에 의해 실리콘층 상에 도포되는 점착제(31)는 후술할 합지부(150)에 의해 흡음재(10)의 일면과 점착되어 상기 흡음재(10)의 일면에서 점착층을 형성할 수 있다.Silicone may be applied to the release paper 20, whereby the pressure-sensitive adhesive 31 applied on the silicone layer is adhered to one surface of the sound-absorbing material 10 by a laminate 150 to be described later, so that the sound-absorbing material 10 An adhesive layer can be formed on one side.

여기서, 점착제(31)는 예를 들어, 주식회사 TTT의 220R 제품(고형분 61%로 분자의 크기가 작게 구성되어 있음)일 수 있으며, 제품의 용제는 톨루엔과 EA로 구성될 수 있다.Here, the pressure-sensitive adhesive 31 may be, for example, a 220R product of TTT Co., Ltd. (61% solid content is composed of a small molecule size), and the solvent of the product may be composed of toluene and EA.

또한, 상기 점착제(31)에는 경화제가 0.01% 첨가될 수 있으며, 상기 경화제는 톨루엔과 EA에 반응 되는 제품으로서, 예를 들어, GE-50라는 제품을 사용할 수 있다.In addition, 0.01% of a curing agent may be added to the pressure-sensitive adhesive 31, and the curing agent is a product that reacts with toluene and EA, and, for example, a product called GE-50 may be used.

그러나, 경화제의 첨가량에 따라 용제가 반응하여 경화(기화)될때 고형분의 점도가 달라지기 때문에, 점착제(31)와 경화제의 혼합비는 유효 적절하게 변경될 수 있다.However, since the viscosity of the solid content changes when the solvent reacts and cures (vaporizes) according to the amount of the curing agent added, the mixing ratio of the pressure-sensitive adhesive 31 and the curing agent can be effectively and appropriately changed.

본 발명은 특히, 상호간 결합력이 매우 약한 PET-FELT 소재의 흡음재(10)의 표면층에 매우 안정적이고 강력한 점착층을 형성할 수 있는 기술적 사상을 제공할 수 있으며, 이에 의해 가전제품 내에 부착된 흡음재(10)의 유지력을 향상시킬 수 있다.In particular, the present invention can provide a technical idea to form a very stable and strong adhesive layer on the surface layer of the sound-absorbing material 10 made of PET-FELT material, which has a very weak mutual bonding force, whereby the sound-absorbing material ( 10) can improve the holding power.
