Description

진동감쇄용 조성물{Composition material for vibration decrease}Composition material for vibration decrease

본 발명은 자동차 내부의 진동을 감쇄하기 위한 조성물에 관한 것으로서, 더욱 상세히는 열에 의해 접착 및 융착이 양호하며 내충격성이 우수하고 넓은 온도범위에서 용이하게 사용할 수 있고 차체의 진동을 보다 효과적으로 제어할 수 있도록 한 진동감쇄용 조성물에 관한 것이다.The present invention relates to a composition for attenuating vibrations in an automobile, and more particularly, has good adhesion and fusion by heat, excellent impact resistance, can be easily used in a wide temperature range, and can more effectively control the vibration of a vehicle body. It relates to a vibration damping composition.

일반적으로 자동차에서 방음의 대상이 되는 소리에는 엔진의 투과음, 풍절음, 기어노이즈, 로드노이즈, 막힘소리 등이 있으며, 방음의 방법에는 차체의 패널 의 진동을 억제하는 제진, 패널을 투과해 나오는 소리를 차단하는 차음, 차실내에서 발생하는 소리를 흡수하는 흡음이 있다.In general, the sound that is the object of soundproofing in a car includes engine transmission sound, wind noise, gear noise, road noise, blockage sound, etc. In the soundproofing method, vibration suppressing vibration of the panel of the vehicle body and sound coming out of the panel Sound insulation to block the sound, sound absorption to absorb the sound generated in the cabin.

여기서 상기 제진은 큰 범위에서 저주파의 진동에 대한 제진과 작은 범위에서 고주파의 진동에 대한 제진으로 구분할 수 있으며, 차실의 공기가 지니는 공동공명의 주파수에서 전자의 진동이 일어나면 막힘 소리가 발생하기 때문에 공동공명의 복판위치에 있는 패널의 진동을 줄이는 방법으로는 곡률, 비드, 보강재, 등에 의하여 패널의 강성을 크게하거나 제진재나 중량물을 부가하기도 한다.The vibration damping can be divided into vibration damping of low frequency vibration in a large range and vibration damping of high frequency vibration in a small range, and when the vibration of the electron occurs at the frequency of the cavity resonance of the cabin air, a clogging sound is generated. As a method of reducing vibration of the panel in the resonance position of the resonance, the rigidity of the panel may be increased by adding curvature, beads, stiffeners, etc., or vibration damping materials or heavy materials may be added.

한편, 상기와 같이 자동차에 사용되는 제진재로는 아스팔트계 제진재가 사용되고 있는데 그 주성분으로는 액상 또는 고상의 아스팔트가 사용되며, 2∼5㎜ 의 시트형태로 적용하고, 부위 및 목적에 따라 접착물질을 추가하여 경사면에도 사용을 할 수 있다.Meanwhile, asphalt-based vibration damping materials are used as the vibration damping materials used in automobiles as described above, and liquid or solid asphalt is used as its main component, and is applied in the form of a sheet of 2 to 5 mm and adhered according to parts and purposes. It can be used on slopes with added material.

그러나 상기와 같은 아스팔트계 제진재는 가격이 저렴하고 보관성 및 작업성이 우수하며 패널에 적용된 후 20℃∼30℃ 에서는 좋은 제진성을 발휘하지만 고온인 40℃∼60℃의 영역에서는 제진성이 거의 상실되는 문제점이 있었다.However, the asphalt-based vibration damper as described above is inexpensive, has excellent storage properties and workability, and exhibits good vibration damping at 20 ° C. to 30 ° C. after being applied to the panel, but has high vibration damping properties at a high temperature of 40 ° C. to 60 ° C. There was a problem almost lost.

따라서 상기와 같은 문제점을 해결하기 위하여 아스팔트계로 이루어진 시트에 부틸러버계의 고무를 주성분으로 하는 부타디엔 수지계의 시트를 스테이플러로 체결하여 적용하기도 한다.Accordingly, in order to solve the above problems, butadiene resin-based sheets containing a butyl rubber-based rubber as a main component may be applied to a sheet made of asphalt based by a stapler.

그러나 상기와 같이 아스팔트계에 부타디엔 수지계를 복층형태로 구성할 경우 고온인 40℃∼60℃의 영역에서는 우수한 제진성을 가지는 반면에 가격이 상대적으로 비싸고 보관성이나 작업성이 떨어지며 품질적으로도 불안정한 문제점이 있었다.However, when the butadiene resin system is composed of a multilayer in the asphalt system as described above, it has excellent vibration damping property in the region of high temperature of 40 ° C. to 60 ° C., while the price is relatively expensive, the storage property and workability are poor, and the quality is unstable. There was a problem.

따라서 본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, EVA(Ethylene Vinyl Acetate)계 수지와 폴리소프렌(Polyisoprene) 고무를 주원료로 하여 열에 의해 접착이나 융착이 양호하면서 내충격성이 우수하고 넓은 온도범위에서 용이하게 사용할 수 있으며 제진효과를 향상시킬 수 있도록 한 진동감쇄용 조성물을 제공하는데 있다.Accordingly, an object of the present invention is to solve the problems described above, and has excellent impact resistance and good adhesion and fusion by heat using EVA (Ethylene Vinyl Acetate) -based resin and polyisoprene rubber as main raw materials. It can be easily used in the temperature range and to provide a vibration damping composition to improve the damping effect.

이와 같은 본 발명의 목적은 EVA계 수지 15∼30 중량％와, 폴리소프렌 고무 5∼15 중량％와, 경화제로 티우람(Tetramethyl-thiuram disulfide) 0.5∼1.2 중량％와, 산화방지제로서 퀴놀린계(Trimehyl-1,2-dihydroquinoline) 0.7∼1.5 중량％와, 난연제로서 수산화알루미늄 3∼9 중량％와, 충전제로서 운모분(Mica powder)5∼15 중량％와, 섬유소인 셀룰로스화이바(Cellulose fiber)3∼10 중량％와, 황산바륨(BaSO4)20∼40 중량％와, 중질탄산칼슘(CaCO3)5∼13 중량％와, 가소제인 프탈레이트계 오일(Dioctyl phthalate oil)2∼6 중량％, 보강성 충전제인 카아본블랙(HAF)3∼5 중량％와, 경량화 충전재인 마이크로펄 3∼10 중량％를 85∼100 ℃ 의 온도로 완전용융 및 혼련 교반될 때 까지 가열하여 상온에서 점성이 없는 진동감쇄용 조성물로 구성하므로서 달성되는 것이다.The object of this invention is 15-30% by weight of EVA-based resin, 5-15% by weight of polysoprene rubber, 0.5-1.2% by weight of tetramethyl-thiuram disulfide as a curing agent, and quinoline-based as an antioxidant (Trimehyl-1,2-dihydroquinoline) 0.7-1.5 wt%, 3-9 wt% aluminum hydroxide as flame retardant, 5-15 wt% Mica powder as filler, Cellulose fiber which is fibrin 3 to 10% by weight, 20 to 40% by weight of barium sulfate (BaSO 4 ), 5 to 13 % by weight of heavy calcium carbonate (CaCO 3 ), 2 to 6% by weight of phthalate oil, which is a plasticizer, 3 to 5% by weight of carbon black (HAF), a reinforcing filler, and 3 to 10% by weight of micropearl, a lightweight filler, were heated to a temperature of 85 to 100 ° C until complete melting and kneading and stirring, thereby making them less viscous at room temperature. It is achieved by configuring a vibration damping composition.

이러한 본 발명은 상기한 목적을 달성하기 위하여 EVA계 수지 15∼30 중량％와, 폴리소프렌 고무 5∼15 중량％와, 경화제로 티우람 0.5∼1.2 중량％와, 산화방지제로서 퀴놀린계 0.7∼1.5 중량％와, 난연제로서 수산화알루미늄 3∼9 중량％와, 충전제로서 운모분 5∼15 중량％와, 섬유소인 셀룰로스화이바 3∼10 중량％와, 황산바륨 20∼40 중량％와, 중질탄산칼슘 5∼13 중량％와, 가소제인 프탈레이트계 오일 2∼6 중량％, 보강성 충전제인 카아본블랙 3∼5 중량％와, 경량화 충전재인 마이크로펄 3∼10 중량％를 85∼100 ℃ 의 온도로 완전용융 및 혼련 교반될 때 까지가열하여 상온에서 점성이 없는 조성물로 구성한 것을 특징으로 하는 것이다.In order to achieve the above object, the present invention provides 15 to 30% by weight of EVA-based resin, 5 to 15% by weight of polysoprene rubber, 0.5 to 1.2% by weight of thiuram as a curing agent, and 0.7 to quinoline as an antioxidant. 1.5% by weight, 3-9% by weight of aluminum hydroxide as flame retardant, 5-15% by weight of mica powder, 3-10% by weight of fiber cellulose fiber, 20-40% by weight of barium sulfate, and heavy calcium carbonate 5 to 13% by weight, 2 to 6% by weight of a phthalate oil as a plasticizer, 3 to 5% by weight of carbon black as a reinforcing filler, and 3 to 10% by weight of micropearl as a lightweight filler at a temperature of 85 to 100 ° C. It is characterized in that it is composed of a composition having no viscosity at room temperature by heating until complete melting and kneading stirring.

한편, 상기 조성물의 주재료로서 EVA계 수지를 15∼30중량％를 사용하는데, 여기서 상기 EVA계 수지를 15중량％ 미만으로 사용하는 경우에는 차체의 패널과 밀착성이 저하될 수 있으며 조성물의 경도를 떨어뜨리는 문제가 발생할 수 있고, EVA계 수지를 30중량％ 이상으로 사용하는 경우에는 내열 유동성에서 흐름성과 경도저하의 문제점이 발생할 수도 있다.On the other hand, 15 to 30% by weight of the EVA-based resin is used as the main material of the composition, when using less than 15% by weight of the EVA-based resin may reduce the adhesiveness to the panel of the vehicle body and the hardness of the composition The problem of shaking may occur, and when the EVA-based resin is used in an amount of 30% by weight or more, problems of flowability and hardness may occur in heat-resistant fluidity.

그리고 폴리소프렌 고무는 5∼15중량％를 사용하는데, 여기서 폴리소프렌 고무를 5중량％ 미만으로 사용하는 경우에는 접착성과 방진성이 저하되는 원인이 되며, 폴리소프렌 고무를 15중량％ 이상으로 사용하는 경우에는 열유동에 문제가 되며 경화성이 저하되는 문제가 발생될 수 있다.In addition, polypropylene rubber is used in the range of 5 to 15% by weight, where the use of polysoprene rubber in less than 5% by weight causes deterioration in adhesion and dust resistance, and the polypropylene rubber is at least 15% by weight. In the case of use, there is a problem of heat flow and a problem of deterioration of the hardenability may occur.

또한 경화제인 티우람은 0.5∼1.2중량％를 사용하는데, 여기서 티우람을 0.5중량％ 미만으로 사용하는 경우에는 경화성이 저하될 우려가 있고, 티우람을 1.2중량％ 이상으로 사용하는 경우에는 경도가 증가하여 목적하는 성능과 안정성이 저하되는 문제점이 발생할 수도 있다.In addition, thiuram, which is a curing agent, is used in an amount of 0.5 to 1.2% by weight. Here, when the thiuram is used at less than 0.5% by weight, the curing property may be lowered. When the thiuram is used at 1.2% by weight or more, Increasingly, there may be a problem that the desired performance and stability are degraded.

그리고 산화방지제인 퀴놀린계는 0.7∼1.5중량％ 를 사용하는데, 여기서 퀴놀린계를 0.7중량％ 미만으로 사용하는 경우에는 제품의 경화가 늦게 진행될 수 있고, 1.5중량％ 이상을 사용하게 되면 제품의 안정성이 떨어지면서 변색이나 제진성능이 저하될 수도 있다.In addition, the quinoline-based antioxidant is used in an amount of 0.7 to 1.5% by weight, wherein when the quinoline is used in an amount less than 0.7% by weight, curing of the product may proceed slowly. The color may fall or the vibration damping performance may decrease.

또한 난연제인 수산화알루미늄은 3∼9중량％를 사용하므로서 차량 내부에 적용시 난연성을 부여하고, 일반적인 중질탄산칼슘과 운모분을 충전제로 사용하여 고온인 60℃ 영역에서의 열유동을 역제할 수 있으며, 진동감쇄 기능을 유지하는데 효과적이며, 선형으로 가공된 셀룰로스화이버를 사용함에 따라 충격에 의한 크랙을 방지할 수 있고, 황산바륨은 진동감쇄에 영향을 주는 첨가제로 -20℃∼60℃ 의 넓은 온도 영역에서 진동감쇄기능을 발휘한다.In addition, aluminum hydroxide, which is a flame retardant, uses 3 to 9% by weight to impart flame retardancy when applied to a vehicle interior and to reverse heat flow in a high temperature range of 60 ° C. by using general heavy calcium carbonate and mica powder as a filler. It is effective in maintaining vibration dampening function, and it is possible to prevent cracking due to impact by using linearly processed cellulose fiber, and barium sulfate is an additive that affects vibration damping and has a wide temperature of -20 ℃ ~ 60 ℃. Demonstrates vibration damping in the area.

여기서 상기 수산화알루미늄을 3중량％ 미만으로 사용하는 경우에는 난연효과가 떨어지고 수산화알루미늄을 9중량％ 이상으로 사용하는 경우에는 작업성이 저하되며 경도가 강해져 처지는 성질인 낙입성이 저하되는 문제점이 발생할 수도 있으며, 운모분은 60∼325 mesh 를 사용하는데 운모분을 60 mesh 미만으로 사용하는 경우 배합이 제대로 이루어지지 않을 수도 있다.In the case where the aluminum hydroxide is used in less than 3% by weight, the flame retardant effect is inferior, and when the aluminum hydroxide is used in an amount of 9% by weight or more, workability is lowered and hardness becomes stronger, which may cause a problem of dropping in falling property. In addition, the mica powder may be 60 to 325 mesh, but when the mica powder is less than 60 mesh, the mixing may not be performed properly.

또한 보강성 충전제이며 착색제인 카본블랙은 3∼5중량％를 사용하므로서 조성물의 강인도를 높여 조성물의 강성을 크게해 주는데 이때 상기 카본블랙을 3중량％ 미만으로 사용하는 경우에는 시트의 강성이 떨어지고, 카본블랙을 5중량％ 이상으로 사용하는 경우에는 경도가 과다하여 크랙이 발생할 수도 있으며 가공시 분산성이 저하되는 원인이 된다.In addition, carbon black, which is a reinforcing filler and coloring agent, uses 3 to 5% by weight to increase the rigidity of the composition to increase the rigidity of the composition.In this case, when the carbon black is used at less than 3% by weight, the rigidity of the sheet is inferior. In the case where the carbon black is used in an amount of 5% by weight or more, the hardness may be excessive and cracks may occur, which may cause dispersibility during processing.

그리고 경량화 충전제인 마이크로펄은 3∼10중량％를 사용하여 조성물의 중량감소와 강성을 부여하게 되는데, 이때 마이크로펄을 10중량％ 이상으로 사용하게 되면 원가가 상승되고 배합성이 떨어지게 되는 문제점이 발생할 수도 있다.In addition, the micropearl, which is a lightweight filler, gives a weight reduction and rigidity of the composition by using 3 to 10% by weight. In this case, when the micropearl is used in an amount of 10% by weight or more, the cost increases and the compoundability decreases. It may be.

상기와 같이 적절한 중량％를 가지는 조성물을 구비한 상태에서 85℃∼100℃의 온도로 50분∼70분 정도 가열하여 완전히 용융 및 혼련 교반되도록 하면 점성이 없는 조성물이 만들어지는 것이며, 이러한 조성물을 시트형태로 구성하여 차량용으로 사용하게 되는 것이다.As described above, if a composition having an appropriate weight percent is provided, it is heated to a temperature of 85 ° C. to 100 ° C. for about 50 to 70 minutes to completely melt and stir the mixture. It is configured in a form that will be used for vehicles.

이상에서 상술한 바와 같이 본 발명은 기존에 사용되는 아스팔트계 제진재의 경우 고온에서 제진성이 저하되는 단점이 있고, 아스팔트계에 부타디엔 수지계를 복층형태로 구성할 경우 고온에서의 제진성은 양호한 반면에 가격이 비싸고 보관성 및 작업성이 불량하고 품질이 저하되는 문제점을 해결할 수 있도록 EVA계 수지와 폴리소프렌 고무를 주원료로 한 조성물을 구성하므로서 열에 의해 접착이나 융착이 양호하면서 작업성 및 내충격성이 우수하고 넓은 온도범위에서 용이하게 사용할 수 있으며 제진효과를 더욱 향상시킬 수 있도록 한 것이다.As described above, the present invention has the disadvantage that the vibration damping property is deteriorated at a high temperature in the case of the conventional asphalt-based vibration damping material, while the damping property at the high temperature is good when the butadiene resin system is configured in the multilayer type. In order to solve the problem of high price, poor storage and workability, and deterioration of quality, it is composed of EVA-based resin and polysoprene rubber as the main raw material, so that adhesion and fusion are good by heat, and workability and impact resistance are good. This excellent and wide temperature range can be used easily and to further improve the damping effect.
