자동차용 소음방지 패드{PAD FOR REDUCING CAR NOIZE}Anti-noise pad for car {PAD FOR REDUCING CAR NOIZE}

본 발명의 자동차용 소음방지 패드에 관한 것으로, 특히 용이한 제조방법과 저렴한 제조비용으로 신속하게 제조할 수 있고 소음방지 및 단열 효과와 내구성 등이 우수한 자동차용 소음방지 패드의 개량에 관한 것이다.The present invention relates to an anti-noise pad for an automobile, and more particularly, to an improvement of an anti-noise pad for an automobile, which can be manufactured quickly with an easy manufacturing method and a low manufacturing cost, and has excellent noise prevention, heat insulation effect, and durability.

일반적으로, 자동차의 보닛(bonnet) 및 데쉬 패널(dash pannel) 등에는 자동차 엔진룸으로부터 발생되는 각종 소음을 효과적으로 차단하기 위한 소음방지 패드가 장착된다.In general, a bonnet and a dash pannel of an automobile are equipped with anti-noise pads for effectively blocking various noises generated from an engine compartment of an automobile.

자동차의 보닛용 및 데쉬 패널용 패드 등과 같은 각종 소음방지 패드는, 대체로 다음과 같이 제조 구성된다.Various anti-noise pads, such as pads for bonnets and dash panels of automobiles, are generally manufactured as follows.

간단히 설명하자면, 일정 크기로 재단한 유리섬유(glass fiber)와 부직포 사이에 수지접착파우더(resin adhesive powder)를 뿌리거나 수지접착액을 도포한 후에 일정한 패드 형태가 되도록 프레스(press)를 이용하여 상하 열접착(열융착) 가공하여서 2단 압착 패드를 구성하는 것이다.Briefly, spraying a resin adhesive powder between a glass fiber and a non-woven fabric cut to a certain size or applying a resin adhesive solution, using a press up and down to form a constant pad shape The thermal bonding (heat welding) process is performed to form a two-stage compression pad.

그러나, 상기와 같은 종래의 자동차용 소음방지 패드는, 제조 시 열접착 시간이 오래 걸리고 부직포 외표면으로 내부 유리섬유 비침현상 방지를 위해 부직포 의 두께를 두껍게 구성해야 하는 등, 소재비용과 에너지비용 등 생산비가 많이 요구되는 것에 비하여 불량률이 높고 생산량이 적은 단점이 있었다. 사용 시에는 패드 내부로 빗물, 습기 등이 침투할 가능성이 크고 내부 수분은 유리섬유와 부직포 간에 화학적 반응을 일으켜 매트 표면에 희뿌연 백화현상을 발생하는 문제점도 있었다. 특히, 저가형 건축용 글라스울(NaOH2)과 같은 유리섬유로 제품을 제조할 경우 매트 표면의 90%이상에 이러한 백화현상이 발생하여 제품의 소재로 사용할 수 없었고, 대체소재로 고급형 글라스울(BaOH2)과 같은 유리섬유를 사용하나 역시 매트 표면의 30%이상에 백화현상이 발생하였고 고가형 소재로 인해 가격경쟁력면에서 매우 취약한 문제점이 있었다. However, the conventional anti-noise pads for automobiles have a long heat-bonding time during manufacture, and the thickness of the nonwoven fabric must be thickened to prevent the non-woven fabric from impregnating with the outer surface of the nonwoven fabric. Compared with the high production cost, the defect rate was high and the yield was low. During use, rainwater, moisture, etc. are more likely to penetrate into the pad, and the internal moisture causes a chemical reaction between the glass fiber and the nonwoven fabric, thereby causing a whitish whitening phenomenon on the mat surface. In particular, the low-end architectural glass wool by these bleaching in more than 90% of the matte surface when manufacturing products made of glass fibers such as (NaOH 2) generated could be used as a material for products, as an alternative material premium glass wool (BaOH 2 ), But also whitening phenomenon occurred on more than 30% of the mat surface, and due to the high-priced material, there was a very weak problem in price competitiveness.

또한, 이렇게 제조된 자동차용 소음방지 패드는 유리섬유 표면의 전반적인 경화현상 때문에 유연성과 탄력성이 좋지 못하며, 상기에서 언급한 바와 같이 여러 가지 변질 가능성이 내재하므로 특히 내구성이 좋지 않았던 것이다.In addition, the anti-noise pad for automobiles manufactured in this way is not good flexibility and elasticity due to the overall curing phenomenon of the glass fiber surface, and as mentioned above, because of the possibility of various deterioration inherent was not particularly durable.

따라서, 본 발명의 목적은, 전체 중량 및 두께는 비교적 감소되고 소음방지 및 단열 효과, 강도와 볼륨감 등은 향상되며, 표면 발수작용으로 백화현상이 방지되고 내구성 등이 우수한 자동차용 소음방지 패드를 제공함에 있다.Therefore, an object of the present invention, the overall weight and thickness is relatively reduced, noise prevention and heat insulation effect, strength and volume is improved, and the surface of the water-repellent action to prevent whitening phenomenon and excellent durability, etc. In providing.

본 발명의 다른 목적은, 비교적 용이 신속하게 제조할 수 있고 재료비, 동력비, 기기설치비 등 제조비용이 감소되도록 한 자동차용 소음방지 패드를 제공함에 있다.Another object of the present invention is to provide an anti-noise pad for an automobile which can be manufactured relatively easily and quickly and reduces manufacturing costs such as material costs, power costs, and equipment installation costs.

상기한 목적에 의하여 본 발명은, 자동차용 소음방지 패드에 있어서, 일체화 접착 경화된 유리섬유매트(11)와 부직포(30) 사이에 용융경화 접착막(22)이 구성되고 최상부면으로 요철면(concave convex face)이 형성되도록 구성하되, 용융경화 접착막(22)이 상기 요면에서는 부직포(30)에 더 접착되고 철면에서는 경화된 유리섬유매트(11)에 더 접착되도록 구성함을 특징으로 한다.In accordance with the above object, the present invention provides an anti-noise pad for automobiles, wherein a melt-cured adhesive film 22 is formed between the integrally adhesive-cured glass fiber mat 11 and the nonwoven fabric 30, and the uneven surface ( Concave convex face) is formed, but the melt-cured adhesive film 22 is characterized in that it is further bonded to the non-woven fabric 30 in the concave surface and further bonded to the hardened glass fiber mat 11 in the iron surface.

본 발명은, 비교적 저렴한 비용을 들여서 쉬운 제조방법으로 신속하게 대량생산할 수 있고, 방음, 흡음, 차음 등 소음방지 및 단열효과가 탁월하며, 패드의 요철면 모양에 따른 부피감과 탄성이 좋고, 부직포 외표면으로 내부 유리섬유가 비 치거나 화학작용에 의한 백화현상 발생의 우려가 없어 내구성이 우수한 등의 장점을 갖는다.The present invention can be mass-produced quickly by an easy manufacturing method at a relatively low cost, excellent soundproofing and sound insulation, sound insulation, sound insulation, etc., good volume and elasticity according to the shape of the uneven surface of the pad, non-woven fabric There is no fear of whitening phenomenon caused by the internal glass fiber shining on the surface or chemical action, and has the advantages of excellent durability.

이하 첨부한 도면을 참조하여 본 발명을 상세히 설명하도록 한다. 각 도면에서 동일한 참조부호는 동일한 기능을 갖는 구성요소를 나타낸다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote components having the same function.

도 1은 본 발명의 자동차용 소음방지 패드 제조에 사용하는 유리섬유매트, 천공비닐시트, 부직포를 상하로 나열한 상태의 사시도이고, 도 2는 도 1의 각 재료를 차례로 적층한 상태의 사시도이며, 도 3은 도 2의 적층 재료를 열접착한 후의 부분 단면도이다. 그리고, 도 4는 본 발명의 바람직한 일 실시 예에 의한 자동차용 소음방지 패드 및 상기 패드의 일측 부직포를 들친 상태의 사시도이고, 도 5는 도 4의 부분 확대 단면도이다.1 is a perspective view of a glass fiber mat, a perforated vinyl sheet, and a nonwoven fabric arranged in an up and down direction for use in manufacturing an anti-noise pad for an automobile according to the present invention, and FIG. 2 is a perspective view of a state in which each material of FIG. 1 is sequentially stacked. 3 is a partial cross-sectional view after thermal bonding the lamination material of FIG. 2. And, Figure 4 is a perspective view of a state of lifting the non-woven fabric of the noise prevention pad and the one side of the pad according to an embodiment of the present invention, Figure 5 is a partially enlarged cross-sectional view of FIG.

본 발명의 소음방지 패드(100)의 제조에 사용되는 소재는 유리섬유매트(10)와 부직포(30) 및 접착용의 천공비닐시트(boring vinylsheet)(20)이다.Materials used in the production of the noise prevention pad 100 of the present invention are a glass fiber mat 10 and a nonwoven fabric 30 and a boring vinyl sheet 20 for bonding.

유리섬유매트(10)와 부직포(30)는 소음방지용 패드에 통상적으로 사용되는 것을 사용한다. 유리섬유매트(10)는 열가소성으로 방음 및 단열재로 널리 사용하며 내열성과 내식성과 내습성이 우수한 것으로 알려져 있다. 또, 본 발명에서 부직포(30)의 두께와 중량은 기존보다 10% ∼ 40%까지 줄여 사용하여도 무방하다.Glass fiber mat 10 and the non-woven fabric 30 is used that is commonly used for noise prevention pads. The glass fiber mat 10 is thermoplastic and is widely used as a sound insulation and heat insulating material, and is known to be excellent in heat resistance, corrosion resistance, and moisture resistance. In addition, in the present invention, the thickness and weight of the nonwoven fabric 30 may be reduced by 10% to 40% than conventional ones.

천공비닐시트(20)는 본 발명의 제조 시 가장 중요한 역할을 하는 것으로 기존의 파우더형 등 수지접착제를 대체한다. 즉, 본 발명에서 사용하는 천공비닐시 트(20)는 폴리에틸렌(polyetylene) 등 접착용 비닐수지(vinyl resin)로 제조된 검정색 계열의 얇은 접착비닐시트에 니들 펀칭(needle punching)으로 천공하여 다수 미세공(21)들을 형성 제조한 것을 사용한다.Perforated vinyl sheet 20 is to play the most important role in the manufacture of the present invention to replace the conventional resin adhesive such as powder type. That is, the perforated vinyl sheet 20 used in the present invention is punched through needle punching on a thin black adhesive vinyl sheet made of an adhesive vinyl resin such as polyethylene (polyetylene). The balls 21 are formed and manufactured.

여기서, 천공비닐시트(20)의 색상은 다음에 설명할 내부의 경화된 유리섬유매트(11)의 색상이 부직포(30) 외표면으로 비치지 않게 덮어줄 수 있는 것으로 설정한다.Here, the color of the perforated vinyl sheet 20 is set so that the color of the hardened glass fiber mat 11 to be described later can be covered so as not to be reflected on the outer surface of the nonwoven fabric 30.

그리고, 도 1 내지 도 3에서와 같이, 일정 크기로 재단한 유리섬유매트(10)와 천공비닐시트(20)와 부직포(30)를 차례로 포개어 겹친 후에 상하에서 프레스로 열과 압력을 가하여 열접착한다. 이를 통해, 보닛용 또는 대쉬 패널용의 소음방지 패널(100)의 제조를 완료하는 것이다.Then, as shown in FIGS. 1 to 3, the glass fiber mat 10 cut to a predetermined size, the perforated vinyl sheet 20, and the nonwoven fabric 30 are stacked in turn, and then heat-bonded by applying heat and pressure with a press from above and below. . Through this, to complete the production of the noise-proof panel 100 for the bonnet or dash panel.

여기서, 열접착 시의 온도는 천공비닐시트(20)의 용융점을 일정 수준 상회하는 200℃ ∼ 230℃가 적합하다. 열접착 시간은 10초(sec) ∼ 2분(min) 내에서 매트 규격별로 조절 가능하나. 자동차 보닛용 패널인 경우는 대체로 1분 정도면 충분하다. 이 과정에서, 유리섬유매트(10)는 내부에 미량 남아 있던 수분이 건조되고 압착 경화되면서 노란색 계통으로 변색되고, 열에 녹으면서 막(membrane)처럼 퍼지는 천공비닐시트(20)에 의하여 부직포(30)와 일체화 접착되는 것이다.Here, the temperature at the time of thermal bonding is suitable 200-230 degreeC which exceeds the melting point of the perforated vinyl sheet 20 by a predetermined level. Heat adhesion time can be adjusted by mat size within 10 seconds (sec) ~ 2 minutes (min). In the case of car bonnet panels, one minute is usually sufficient. In this process, the glass fiber mat 10 is a non-woven fabric (30) by the perforated vinyl sheet 20, which is discolored to a yellow system as the moisture remaining in the inside is dried and squeezed and hardened, and melted in heat and spread like a membrane (membrane). It is integrally bonded with.

특히, 본 발명에서 접착용의 천공비닐시트(20)는 그 두께를 1㎜ 이내, 바람직하게는 0.02㎜ ∼ 0.05㎜로 형성하는 바, 이보다 두꺼우면 열접착 시간이 오래 걸리고 이보다 얇으면 접착제 양이 부족하여 접착이 잘되지 않고 부직포(30) 들뜸현상이 생기게 된다.Particularly, in the present invention, the perforated vinyl sheet 20 for adhesion is formed within 1 mm, preferably 0.02 mm to 0.05 mm. If the thickness is larger than this, the thermal bonding time takes longer and if the thickness is thinner than the amount of the adhesive, Lack of adhesion is not good and the nonwoven fabric 30 is raised.

또, 천공비닐시트(20)에는 열접착 시 발생하는 가스(gas) 제거 역할을 하는 다수 미세공(21)들을 구성하는 것이 매우 중요하다. 이때, 상기 미세공(21)의 지름은 1.5㎜ ∼ 2.5㎜, 바람직하게는 2㎜ 정도 되고, 미세공(21) 간의 간격은 5㎜ ∼ 30㎜, 바람직하게는 10㎜가 되도록 천공한다.In addition, the perforated vinyl sheet 20 is very important to configure a plurality of micro-pores (21) that serves to remove the gas (gas) generated during thermal bonding. At this time, the diameter of the micropores 21 is 1.5 mm to 2.5 mm, preferably about 2 mm, and the space between the micropores 21 is 5 mm to 30 mm, preferably 10 mm.

천공비닐시트(20)의 미세공(21)들 크기 및 간격이 상기 범위를 벗어나면 열접착 시에 발생하는 수지 가스가 전부 빠지지 못하고 잔류하면서 기포에 의한 들뜸현상이 군데군데 발생할 수 있으므로 바람직한 양품 생산에 어려움이 있다.If the size and spacing of the micropores 21 of the perforated vinyl sheet 20 are out of the above ranges, all of the resin gas generated during thermal bonding may not be released and residual lifting may be caused by bubbles. There is a difficulty.

지금까지 설명한 바와 같이 제조된 본 발명의 소음방지 패드(100)는, 도 4 내지 도 5에 도시한 바와 같이, 경화된 유리섬유매트(11)와 부직포(30)의 일체화 접착되고 그 사이에 용융경화 접착막(22)이 구성되며 최상부면으로 요철면(concave convex face)이 형성 구성된다.The noise prevention pad 100 of the present invention manufactured as described above is integrally bonded to the cured glass fiber mat 11 and the nonwoven fabric 30 and melted therebetween, as shown in FIGS. 4 to 5. The cured adhesive film 22 is formed, and a concave convex face is formed on the uppermost surface.

용융경화 접착막(22)은 천공비닐시트(20)가 경화된 유리섬유매트(11)와 부직포(30) 사이에서 열접착 시에는 녹았다가 실온에서 다시 경화되어 우수한 접착역할을 하면서 변형된 것이다.The melt-cured adhesive film 22 is melted during thermal bonding between the glass fiber mat 11 and the nonwoven fabric 30 in which the perforated vinyl sheet 20 is cured, and is cured again at room temperature to deform while performing an excellent adhesive role. .

소음방지 매트(100)를 요철면으로 형성하여 유리섬유매트(11)와 부직포(30)를 수지접착액으로 접착할 경우는 요철면의 형상으로 인해 요면과 부직포(30)간, 철면과 경화된 유리섬유매트(11)간에는 접착력이 약화되고 부재간 들뜸현상이 심화된다. 그러나, 본 발명에서는 유리섬유매트(11)와 부직포(30) 사이에 천공비닐시트(20)를 용융시켜 접착하므로 접착성이 우수하고 부재간 박리현상이 방지된다. 특히, 수지접착액으로 접착할 경우 들뜸현상이 발생하는 요면과 부직포(30)간, 철면 과 경화된 유리섬유매트(11)간에는 접착력이 더 강화된다.When the anti-noise mat 100 is formed with the uneven surface to bond the glass fiber mat 11 and the nonwoven fabric 30 with the resin adhesive, the uneven surface between the uneven surface and the nonwoven fabric 30 due to the uneven surface is cured with the iron surface. Adhesion is weakened between the glass fiber mat 11 and the lifting phenomenon between the members is intensified. However, in the present invention, since the perforated vinyl sheet 20 is melted and adhered between the glass fiber mat 11 and the nonwoven fabric 30, the adhesiveness is excellent and the separation between members is prevented. In particular, the adhesive strength between the concave surface and the nonwoven fabric 30, the iron surface and the cured glass fiber mat 11, which is raised when the resin adhesive is bonded to the adhesive strength is further strengthened.

이에, 상기 요면부의 경화된 유리섬유매트(10)는 자체 볼륨감 및 탄성이 유지되어 사용자에게 폭신하고 안정된 느낌을 부여할 수 있다.Accordingly, the cured glass fiber mat 10 of the concave portion may maintain its volume and elasticity to give the user a fluffy and stable feeling.

또, 용융경화 접착막(22)이 방수막(waterproof membrane) 역할을 하므로 유리섬유와 부직포와 수분의 화학작용에 의한 소음방지 패드(100) 표면의 백화현상을 방지해 준다. 그리고, 가격경쟁력이 우수한 저가형 글라스울(NaOH2)과 같은 유리섬유매트(10)를 사용할 수 있어 생산단가가 낮아지는 장점이 있다. 또한, 검정색 계열 등 용융경화 접착막(22)의 색상에 의하여, 부직포(30)의 두께 및 중량을 기존보다 감소 구성하더라고 유리섬유매트(10)의 노란 색상이 외표면으로 비치는 현상이 완벽 차단되는 것이다.In addition, the melt-cured adhesive film 22 serves as a waterproof membrane (waterproof membrane) to prevent the whitening of the surface of the noise prevention pad 100 by the chemical action of glass fiber, non-woven fabric and moisture. In addition, it is possible to use a glass fiber mat 10, such as low-cost glass wool (NaOH 2 ) with excellent price competitiveness, there is an advantage that the production cost is lowered. In addition, by the color of the melt-cured adhesive film 22, such as a black series, even if the thickness and weight of the nonwoven fabric 30 is reduced than before, the phenomenon that the yellow color of the glass fiber mat 10 is reflected to the outer surface is completely blocked. will be.

이상으로 설명한 본 발명에서는 천공비닐시트(20)를 통하여 쉽고 빠르고 저렴한 비용으로 소음방지 효과와 내구성 등이 현저히 개량된 자동차용 소음방지 패드(100)를 제조 구성한 것을 예로 들어 설명하였으나, 이의 제조방법 및 구성은 본 발명의 범위 내에서 다양하게 변경할 수 있는 것이다. 따라서, 본 발명의 범위는 설명된 실시 예에 의하여 정할 것이 아니고 특허청구범위와 특허청구범위의 균등한 것에 의해 정해져야 한다.In the present invention described above has been described for the manufacture and configuration of the noise prevention pad 100 for automobiles, which is significantly improved noise prevention effect and durability at an easy, fast and low cost through the perforated vinyl sheet 20, but the manufacturing method and The configuration can be variously changed within the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.
