Description

자동차용 흡차음재 { A SOUND ABSORBING AND INSULATING MATERIAL FOR AUTOMOBILE }Sound absorption material for automobiles {A SOUND ABSORBING AND INSULATING MATERIAL FOR AUTOMOBILE}

본 발명은 자동차용 흡차음재에 관한 것으로서, 특히 자동차에 장착되어 자동차로부터 발생하는 소음을 차단 및 흡수하는 자동차용 흡차음재에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sound absorbing and insulating materials for automobiles, and more particularly, to sound absorbing and insulating materials for automobiles which are mounted on automobiles and block and absorb noise generated from automobiles.

일반적으로 자동차는 주행하는 도중 엔진으로부터 소음, 진동 및 열이 지속적으로 발생하게 된다. In general, a car generates noise, vibration and heat continuously from an engine while driving.

특히 소음은 인스트루먼트 패널을 통하여 내부로 침투하는 한편, 차체나 차체의 틈을 통하여 외부로 누출된다.In particular, noise penetrates internally through the instrument panel, while leaking outside through the body or the gap of the body.

따라서 차량의 내부에 탑승한 사람은 차량의 실내로 침투한 소음으로부터 피해를 받게 되고, 차량의 외부의 사람 또한 엔진으로부터 누출된 소음에 의해 피해를 받게 된다. Therefore, a person in the interior of the vehicle is damaged by noise penetrating into the interior of the vehicle, and the person outside of the vehicle is also damaged by the noise leaked from the engine.

이러한 피해를 방지하기 위하여 인스트루먼트 패널이나 후드의 내측면 또는 차량의 내부 패널에 소음을 차단 및 흡수하는 흡차음재를 부착한다.In order to prevent such damage, a sound absorbing and insulating material for blocking and absorbing noise is attached to the inner surface of the instrument panel or hood or the inner panel of the vehicle.

이러한 흡차음재는 비중이 무거운 고무종류인 헤비레이어(HEAVY LAYER)를 재료로 한 제품이나, 비중이 가볍고 내부에 많은 기포구멍을 함유하도록 제조된 폴리 우레탄폼(POLYURETAHNE FORM)이 주로 사용된다. Such sound absorbing and insulating material is a product made of HEAVY LAYER, which is a kind of heavy rubber, but a polyurethane foam manufactured to have a specific gravity and contain many bubble holes therein is mainly used.

도 1 은 종래의 자동차용 흡차음재를 도시한 단면도이다.1 is a cross-sectional view showing a conventional sound absorbing and insulating material for automobiles.

도 1 에 도시된 바와 같이 종래의 자동차용 흡차음재는 제 1 표면층(10), 흡차음층(20) 및 제 2 표면층(30)을 포함하여 이루어진다.As shown in FIG. 1, a conventional sound absorbing and insulating material for automobiles includes a first surface layer 10, a sound absorbing and insulating layer 20, and a second surface layer 30.

상기 제 1 표면층(10) 및 상기 제 2 표면층(30)은 폴리에스테르 섬유로 이루어진 부직포가 사용된다.As the first surface layer 10 and the second surface layer 30, a nonwoven fabric made of polyester fiber is used.

상기 제 1 표면층(10)과 상기 제 2 표면층(30) 사이에 형성된 상기 흡차음층(20)은 폴리우레탄 폼을 발포시킨 형태로 형성된다.The sound absorbing and insulating layer 20 formed between the first surface layer 10 and the second surface layer 30 is formed in a foamed polyurethane foam.

위와 같이 형성된 종래의 자동차용 흡차음재는 자동차 후드의 내측면이나 인스트루먼트 패널 또는 자동차 내부의 패널에 접착되어 설치된다. The conventional sound absorbing and insulating material for automobiles formed as described above is attached to an inner surface of an automobile hood or an instrument panel or a panel inside an automobile.

따라서 상기 흡차음재는 자동차 엔진과 같은 소음원으로부터 전달된 소음의 일부를 반사시켜 외부로 보내고, 일부는 감쇄 소멸시켜 방음 역할을 하게 된다.Therefore, the sound absorbing and insulating material reflects a part of the noise transmitted from the noise source such as an automobile engine and sends it to the outside, and part of the sound absorbing and attenuating function.

이와 같은 폴리우레탄폼을 사용한 종래의 자동차용 흡차음재는 비중이 낮아 연비에는 좋지만 강도가 낮아 내구성이 떨어지는 문제점이 있다. Conventional automobile sound absorbing and insulating material using such a polyurethane foam has a low specific gravity is good for fuel economy, but the strength is low, there is a problem that durability is poor.

또한 흡음성은 좋으나 차음기능이 낮아 전체적인 방음 성능이 떨어지는 문제점이 있다.In addition, sound absorption is good, but the sound insulation is low, there is a problem that the overall sound insulation performance is lowered.

본 발명은 전술한 문제점을 해결하기 위하여 안출된 것으로서, 자동차에 장착되어 소음을 차단 및 흡수하는 흡차음재의 강도를 높여 내구성을 향상시키고, 방음기능이 강화된 자동차용 흡차음재 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, the purpose of the present invention is to increase the strength of the sound absorbing and insulating material to block and absorb the noise mounted on the car to improve the durability, and to provide a sound absorbing and insulating material for automobiles with enhanced sound insulation function. .

상기 목적을 달성하기 위하여 본 발명의 자동차용 흡차음재는 제 1 표면층과; 제 2 표면층과; 상기 제 1 표면층과 제 2 표면층 사이에 배치되는 흡차음층으로 이루어지되, 상기 흡차음층은 폴리에스테르섬유로 이루어진다.In order to achieve the above object, the automobile sound absorbing and insulating material of the present invention includes a first surface layer; A second surface layer; The sound absorbing and insulating layer is disposed between the first surface layer and the second surface layer, the sound absorbing and insulating layer is made of polyester fibers.

상기 제 1 표면층과 제 2 표면층은 폴리에스테르섬유로 이루어지되, 상기 제 1 표면층 및 상기 제 2 표면층의 밀도는 상기 흡차음층의 밀도보다 크다.The first surface layer and the second surface layer are made of polyester fiber, the density of the first surface layer and the second surface layer is greater than the density of the sound absorbing and insulating layer.

상기 제 1 표면층과 흡차음층 및 상기 제 2 표면층과 흡차음층은 니들펀칭 결합 된다. The first surface layer and the sound absorbing and insulating layer, and the second surface layer and the sound absorbing and insulating layer are needle punched.

상기 제 1 표면층 또는 제 2 표면층과 상기 흡차음층 사이에는 접착필름이 배치된다.An adhesive film is disposed between the first surface layer or the second surface layer and the sound absorbing and insulating layer.

상기 접착필름의 녹는점은 상기 제 1 표면층, 제 2 표면층 및 흡차음층의 녹는점보다 낮다.The melting point of the adhesive film is lower than the melting point of the first surface layer, the second surface layer and the sound absorbing and insulating layer.

이상에서 설명한 바와 같은 본 발명의 자동차용 흡차음재에 따르면 다음과 같은 효과가 있다.According to the sound absorbing and insulating material for automobiles of the present invention as described above has the following effects.

상기 제 1 표면층과 상기 제 2 표면층 사이에 배치되는 상기 흡차음층을 폴리에스테르섬유로 형성함으로써, 상기 흡차음재의 전체적인 강도를 높이고 방음성능을 향상시키는 효과가 있다. By forming the sound absorbing and insulating layer disposed between the first surface layer and the second surface layer with polyester fiber, there is an effect of increasing the overall strength of the sound absorbing and insulating material and improving the sound insulation performance.

또한, 상기 제 1 표면층 및 상기 제 2 표면층을 상기 흡차음층보다 밀도를 크게 형성함으로써 차음기능을 향상시키고, 분진의 유출을 방지하는 효과가 있다. In addition, by forming the first surface layer and the second surface layer to have a greater density than the sound absorbing and insulating layer, there is an effect of improving the sound insulation function and preventing the outflow of dust.

상기 제 1 표면층과 상기 흡차음층 또는 상기 제 2 표면층과 상기 흡차음층을 니들펀칭결합함으로써, 상기 제 1 표면층과 상기 흡차음층의 결합력을 항상시키고, 제작 비용을 절감하는 효과가 있다. By needle punching the first surface layer and the sound absorbing and insulating layer or the second surface layer and the sound absorbing and insulating layer, the bonding force between the first surface layer and the sound absorbing and insulating layer is always maintained and manufacturing cost is reduced.

또한 상기 제 2 표면층과 상기 흡차음층 사이에 접착 필름을 배치함으로써, 상기 제 2 표면층과 상기 흡차음층이 결합되게 한다. In addition, by disposing an adhesive film between the second surface layer and the sound absorbing and insulating layer, the second surface layer and the sound absorbing and insulating layer are bonded.

상기 접착필름의 녹는점이 낮아 상기 제 1 표면층 또는 상기 제 2 표면층이 상기 흡차음층에 쉽게 접착될 수 있게 한다. The melting point of the adhesive film is low so that the first surface layer or the second surface layer can be easily adhered to the sound absorbing and insulating layer.

도 2 는 본 발명의 실시예에 따른 자동차용 흡차음재의 단면도이다.2 is a cross-sectional view of a sound absorbing and insulating material for an automobile according to an exemplary embodiment of the present invention.

도 2 에 도시된 바와 같이 본 발명의 자동차용 흡차음재는 제 1 표면층(100), 흡차음층(200), 접착필름(300) 및 제 2 표면층(400)을 포함하여 이루어진 다.As shown in FIG. 2, the sound absorbing and insulating material for automobiles of the present invention includes a first surface layer 100, a sound absorbing and insulating layer 200, an adhesive film 300, and a second surface layer 400.

상기 제 1 표면층(100)은 폴리에스테르섬유로 이루어지는 부직포이며, 300g/㎡의 단위중량을 갖는다. The first surface layer 100 is a nonwoven fabric made of polyester fiber, and has a unit weight of 300 g / m 2.

상기 제 1 표면층(100)은 폴리에스테르섬유를 높은 밀도로 압축하여 단단하게 형성되지만 두께는 상기 흡차음층(200) 보다 얇게 형성된다. The first surface layer 100 is formed hard by compressing the polyester fiber to a high density, but the thickness is formed thinner than the sound absorbing and insulating layer 200.

위와 같이 단단하게 형성된 제 1 표면층(100)은 흡음기능보다는 차음기능이 더 강하다.The first surface layer 100 formed firmly as described above has a stronger sound insulation function than a sound absorption function.

또한, 밀도가 높은 상기 제 1 표면층(100)은 상기 흡차음층(200)에서 발생하는 분진이 외부로 유출되지 않게 하는 기능도 한다. In addition, the first surface layer 100 having a high density also functions to prevent dust generated in the sound absorbing and insulating layer 200 from leaking to the outside.

상기 제 1 표면층(100)의 하단에는 상기 흡차음층(200)이 적층되어 결합된다.The sound absorbing and insulating layer 200 is stacked and coupled to a lower end of the first surface layer 100.

상기 흡차음층(200)은 상기 제 1 표면층(100)과 같이 폴리에스테르섬유로 이루어지지만, 상기 제 1 표면층(100)보다 밀도는 낮다. The sound absorbing and insulating layer 200 is made of polyester fiber like the first surface layer 100, but has a lower density than the first surface layer 100.

흡차음층(200)의 단위중량은 약 600g/㎡ 정도이며, 상기 제 1 표면층(100)보다 두껍게 형성된다. The unit weight of the sound absorbing and insulating layer 200 is about 600 g / m 2, and is thicker than the first surface layer 100.

상기 제 1 표면층(100)보다 밀도가 낮은 상기 흡차음층(200)은 스폰지와 같이 내부에 공기가 많이 함유되어있어 차음기능 보다는 흡읍기능이 더 강하게 나타난다.The sound absorbing and insulating layer 200 having a lower density than the first surface layer 100 contains a lot of air, such as a sponge, so that the suction function is stronger than the sound insulating function.

폴리에스테르섬유로 이루어진 상기 흡차음층(200) 및 상기 제 1 표면층(100)은 별도의 접착제 없이 니들펀칭결합되어 제조 비용이 절감되는 효과가 있다.The sound absorbing and insulating layer 200 and the first surface layer 100 made of polyester fibers are needle punching combined without a separate adhesive has the effect of reducing the manufacturing cost.

또한 상기 흡차음층(200)과 상기 제 1 표면층(100)을 같은 재질로 형성함으로써 상호간의 결합력이 높아지는 효과가 있다. In addition, by forming the sound absorbing and insulating layer 200 and the first surface layer 100 of the same material, there is an effect of increasing the mutual bonding force.

니들펀칭결함은 고리형상의 바늘을 이용하여 상호간의 섬유사를 서로 엉키게 하여 결합시키는 것이다.Needle punching defect is to entangle each other's fiber yarns by using a ring-shaped needle.

물론, 상기 제 1 표면층(100)과 상기 흡차음층(200) 사이에 접착제 등을 사용하여 결합시킬 수도 있으나, 추가 비용이 발생하기 때문에 사용하지 않는 것이 바람직하다. Of course, the first surface layer 100 and the sound absorbing and insulating layer 200 may be bonded using an adhesive or the like, but it is preferable not to use because of the additional cost.

상기 흡차음층(200)의 하단에는 상기 접착필름(300)과 상기 제 2 표면층(400)이 순차적으로 적층된다. The adhesive film 300 and the second surface layer 400 are sequentially stacked on the lower end of the sound absorbing and insulating layer 200.

상기 제 2 표면층(400)은 상기 제 1 표면층(100)과 같이 폴리에스테르섬유로 이루어지는 부직포가 사용되며, 약 300g/㎡의 단위중량을 갖는다. As for the second surface layer 400, a nonwoven fabric made of polyester fiber is used as the first surface layer 100, and has a unit weight of about 300 g / m 2.

상기 제 2 표면층(400)은 폴리에스테르섬유를 높은 밀도로 압축하여 단단하게 형성되지만 두께는 상기 흡차음층(200)보다 얇다. The second surface layer 400 is hardly formed by compressing the polyester fiber to a high density, but the thickness is thinner than the sound absorbing and insulating layer 200.

위와 같이 단단하게 형성된 제 2 표면층(400)은 흡음기능보다는 차음효과가 크게 나타난다.As described above, the second surface layer 400 hardly formed exhibits a larger sound insulating effect than a sound absorbing function.

또한 밀도가 높은 상기 제 2 표면층(400)은 폴리에스테르섬유에서 발생하는 분진이 외부로 유출되지 않게 하는 기능도 한다. In addition, the second surface layer 400 having a high density also functions to prevent dust generated from polyester fibers from leaking to the outside.

한편, 상기 접착필름(300)은 상기 흡차음재와 상기 제 2 표면층(400) 사이에 배치되며, 상기 접착필름(300) 가열시 융해되어 상기 흡차음층(200)과 상기 제 2 표면층(400)이 접착되게 한다. On the other hand, the adhesive film 300 is disposed between the sound absorbing and insulating material and the second surface layer 400, it is melted when the adhesive film 300 is heated, the sound absorbing and insulating layer 200 and the second surface layer 400 Let this bond.

물론 상기 흡차음층(200)과 상기 제 2 표면층(400)을 니들펀칭결합 할 수도 있으나 본 실시예에서는 상기 접착필름(300)으로 결합한다. Of course, the sound absorbing and insulating layer 200 and the second surface layer 400 may be needle punched, but in the present embodiment, the adhesive film 300 is bonded.

또한 상기 접착필름(300)은 상기 제 1 표면층(100)과 상기 흡차음재(200) 사이에 배치되어 상호 결합 되게 할 수도 있다. In addition, the adhesive film 300 may be disposed between the first surface layer 100 and the sound absorbing and insulating material 200 to be mutually coupled.

상기 접착필름(300)이 삽입된 상기 흡차음층(200)과 상기 제 2 표면층(400)은 가열된 롤러를 통과하면서 접착된다.The sound absorbing and insulating layer 200 and the second surface layer 400 into which the adhesive film 300 is inserted are bonded while passing through the heated roller.

위와 같이 롤러를 사용하면 골고루 열이 잘 전달될 뿐만 아니라 두께조절도 가능하기 때문에 효율적이다. If you use the roller as above, it is efficient because not only the heat is evenly transmitted but also the thickness can be adjusted.

또한 상기 접착필름(300)은 상기 제 1 표면층(100), 상기 흡차음재 및 상기 제 2 표면층(400)보다 녹는점을 낮게 구성하여 상기 접착필름(300)의 가열시 상기 제 1 표면층(100), 상기 흡차음재 및 상기 제 2 표면층(400)이 손상되는 것을 방지한다.In addition, the adhesive film 300 has a lower melting point than the first surface layer 100, the sound absorbing and insulating material, and the second surface layer 400 so that the first surface layer 100 is heated when the adhesive film 300 is heated. In addition, the sound absorbing and insulating material and the second surface layer 400 are prevented from being damaged.

위와 같이 형성된 자동차용 흡차음재는 자동차 후드 등에 부착되어 엔진에서 발생하는 소음을 차단 및 흡수한다.The vehicle sound absorbing and insulating material formed as described above is attached to the car hood, etc. to block and absorb the noise generated by the engine.

따라서 상기 제 1 표면층(100) 및 상기 제 2 표면층(400)은 일차적으로 소음을 차단시키고, 상기 제 1 표면층(100)에서 차단되지 못한 소음은 상기 흡차음재를 통과하면서 흡수된다.Accordingly, the first surface layer 100 and the second surface layer 400 primarily block the noise, and the noise that is not blocked in the first surface layer 100 is absorbed while passing through the sound absorbing and insulating material.

특히 폴리에스테르섬유로 형성된 상기 흡차음재는 차음과 흡음 기능을 같이 수행하여 기존대비 약 20% 정도의 성능향상을 보인다.In particular, the sound absorbing and insulating material formed of polyester fiber performs a sound insulating and sound absorbing function together shows a performance improvement of about 20%.

또한 상기 자동차용 흡차음재는 상기 제 1 표면층(100)과 상기 제2 표면층을 비롯하여 상기 흡차음재를 모두 폴리에스테르섬유를 사용하여 형성함으로써, 강도와 내구성이 향상된다.In addition, the sound absorbing and insulating material for automobiles is formed by using both polyester and the sound absorbing and insulating material including the first surface layer 100 and the second surface layer, thereby improving strength and durability.

다시 말해서 상기 자동차용 흡차음재는 설치 부분에 따라 여러 윤곽형태로 형성되는데, 강도가 높은 폴리에스테르로 형성된 상기 자동차용 흡차음재는 그 형상을 잘 유지할 수 있게 된다.In other words, the vehicle sound absorbing and insulating material is formed in various contours according to the installation portion, the vehicle sound absorbing and insulating material formed of high strength polyester can maintain its shape well.

또한 폴리에스테르섬유로 이루어진 상기 자동차용 흡차음재는 거의 100% 재활용이 가능하며, 환경유해 물질이 거의 포함되어 있지 않아 환경 친화적인 제품으로 생산할 수 있다.In addition, the sound absorbing and insulating material for automobiles made of polyester fiber can be recycled almost 100%, and contains little environmentally harmful substances, thereby producing environmentally friendly products.
