본 고안은 흡음효과를 갖는 제진판(制振板)에 관한 것으로서, 보다 상세 하게는 소음 및 진동 방지용 재료로 사용되는 흡음효과를 갖는 제진판에 관한 것이다.The present invention relates to a vibration damping plate having a sound absorption effect, and more particularly to a vibration damping plate having a sound absorption effect used as a material for preventing noise and vibration.

종래에는 세탁기와 같은 회전기기에 있어서 모타의 회전이나 기계적 작동으로 인하여 발생되는 소음과 진동을 감소시키기 위하여 세탁기 몸체를 고가의 제진 강판으로 만들거나, 일반 강판으로 제작된 몸체 내측벽에 아스팔트시트나 고무시트를 제진판으로 부착 사용하였다.Conventionally, in a rotating machine such as a washing machine, in order to reduce noise and vibration generated by the rotation or mechanical operation of the motor, the washing machine body is made of expensive vibration damping steel plate, or asphalt sheet or rubber on the inner wall of the body made of ordinary steel plate. The sheet was attached and used as a vibration damping plate.

그러나 종래의 이러한 제진판은 다음과 같은 문제점을 갖고 있다.However, such a damping plate of the related art has the following problems.

즉, ① 제진 강판의 경우는 중량이 상당히 무겁고 값이 비싸다는 단점이 있으며, ② 아스팔트시트나 고무시트로 구성된 제진판의 경우는 제진강판에 비해 값은 싸지만 제진 강판과 마찬가지로 중량이 상당히 무거워 일반 강판으로 제작된 몸체 내측벽에 대한 부착력이 약하고, ③ 발생된 소음을 흡수하지 못한다는 점이 문제점으로 되어 있다.That is, ① damping steel sheet has the disadvantage that the weight is quite heavy and expensive, ② the damping plate composed of asphalt sheet or rubber sheet is cheaper than the damping steel sheet, but the weight is considerably heavy like the damping steel sheet The problem is that the adhesion to the inner wall of the body made of steel is weak, and ③ does not absorb the generated noise.

이에 본 고안은 종래의 이러한 제반 문제점들을 개선하기 위해 제진 강판이나 아스팔트시트 또는 고무시트로 구성된 제진판 대신 중량이 가볍고 값이 싼 아스팔트 함침 조이패드층 또는 제진성 충진제를 포함한 고무층위에 폴리우레탄 스폰지를 적층한 형태의 제진판을 구성 함으로서 무게의 경량화 및 제조비용을 절감시키며, 우수한 제진효과를 유지하면서 동시에 흡음효과까지 얻을 수 있다는 것을 확인하고 본 고안을 완성 하였다.Therefore, the present invention is to laminate the polyurethane sponge on the rubber layer including the light weight and cheap asphalt impregnated joy pad layer or the damping filler in place of the damping plate consisting of a damping steel sheet or asphalt sheet or rubber sheet to improve the conventional problems. By constructing a vibration damping plate of the form, the weight and weight of the manufacturing cost can be reduced, and while maintaining the excellent vibration damping effect, the sound absorption effect can be obtained and the present invention was completed.

본 고안에 따른 흡음효과를 갖는 제진판은 아스팔트 함침 종이 패드층 또는 제진성 충진제를 포함한 고무층위에 폴리우레탄 스폰지층을 적층시킨 형태를 특징으로 하는 것이다.The damping plate having a sound absorbing effect according to the present invention is characterized in that a polyurethane sponge layer is laminated on a rubber layer including an asphalt-impregnated paper pad layer or a damping filler.

이하 첨부도면에 의거하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1 도는 본 고안품의 일실시예의 구성을 보여주는 사시도이다.1 is a perspective view showing the configuration of an embodiment of the present invention.

(1)은 폴리우레탄 스폰지층으로서 소음을 흡수하고 약간의 제진 역할을 하는 것으로, 그 두께는 5~20mm정도가 바람직하며 종류에는 특별한 제한이 없으나 바람직한 것은 비중이 높은 충진제, 예를들면 탄산 칼슘이 폴리우레탄 스폰지에 처리된 것이다. 이때 폴리우레탄 스폰지층 표면에 합성 수지 필름까지 부가할 경우 차음된 후의 잔여음만 흡수해도 되므로 그 흡음효과는 더욱 좋아진다. (2)는 아스팔트 함침 종이 패드층 또는 제진성 충진제를 포함한 고무층으로서 대부분의 진동을 흡수하는 역할을 하며 그 두께는 1~3mm 정도가 바람직하고 이때 사용되는 아스팔트 함침 종이 패드란 목면과 펄프를 주로하여 제조된 종이에 석유 아스팔트, 예를 들면 블로운 아스팔트나 스트레이트 아스팔트 등을 함침 시켜 제조된 통상적인 것을 말하는 것으로 본 고안품의 경우 그 종류에 특별한 제한은 없다. 또한 고무층에 사용되는 고무 및 제진성 충진제의 종류도 특별한 제한은 없으나 제진성 충진제의 경우는 운모와 같은 판상형의 충진제가 바람직하다. (3)는 점접착제로써 조립작업시 별도의 접착제 사용없이 일정 장소에 보다 용이하게 제진판을 부착시킬 수 있도록 하는 역할을 하며, 이때 사용되는 점접착제는 특별한 제한이 없고 통상의 점착제를 사용한다. (4)는 이형지로써 제진판의 조립사용시까지 아스팔트 함침 종이 패드층 또는 제진성 충진제를 포함하는 고무층(2) 하부에 기 처리된 점접착제(3)를 보호하고 조립사용시 외에는 다른 물품과 접착되는 일이 없도록 하는 역활을 한다. 이때 사용되는 이형지는 특별한 제한이 없고 통상의 이형지를 사용한다.(1) is a polyurethane sponge layer that absorbs noise and plays a role in dust suppression. The thickness thereof is preferably about 5 to 20 mm, and there is no particular limitation on the type, but the preferred one is a high specific gravity filler such as calcium carbonate. Treated with polyurethane sponge. In this case, when the synthetic resin film is added to the surface of the polyurethane sponge layer, only the remaining sound after the sound insulation may be absorbed. (2) is an asphalt impregnated paper pad layer or a rubber layer containing a damping filler to absorb most vibrations, the thickness is preferably about 1 ~ 3mm, and the asphalt impregnated paper pad used in this case is mainly made of cotton and pulp The present invention refers to a conventional one manufactured by impregnating petroleum asphalt, for example, blown asphalt or straight asphalt, and the present invention is not particularly limited in kind. In addition, the type of rubber and the damping filler used in the rubber layer is not particularly limited, but in the case of the damping filler, a plate-like filler such as mica is preferable. (3) serves as an adhesive to easily attach the vibration damping plate to a certain place without the use of an additional adhesive during the assembly work, and the adhesive used here is not particularly limited and uses a common adhesive. (4) is a release paper to protect the pre-treated adhesive agent (3) in the lower part of the rubber layer (2) containing the asphalt-impregnated paper pad layer or the vibration damping filler until the assembly use of the vibration damping plate and to be bonded to other articles except for the assembly use It plays a role to prevent this. At this time, the release paper used is not particularly limited and uses a conventional release paper.

제 2 도는 제 1 도에 도시된 본 고안품의 A-A' 확대 단면도이다.FIG. 2 is an enlarged sectional view taken along line A-A 'of the present invention shown in FIG.

제 3 도는 제 1 도에 도시된 이형지(4)를 분리 제거해 가면서 제진판을 부착하는 상태를 나타내는 사용상태도이다.3 is a use state diagram showing a state in which a damping plate is attached while separating and removing the release paper 4 shown in FIG.

본 고안의 효과를 설명하면, 본 고안은 흡음효과와 제진효과를 동시에 갖는 폴리우레판 스폰지층을 표면에 적층시킴으로써, 별도의 흡음 재료의 사용없이도 흡음효과까지 얻을 수 있어 생산원가가 절감되며, 복층 구조로 이루어짐으로써 얇은 두께로도 탁월한 제진효과를 얻을 수 있으므로 아스팔트시트나 고무시트만으로 구성된 종래의 제진판에 비해 중량이 50% 이상 가벼워져서 이를 이용한 제품의 경량화 효과를 나타내고 있다.When explaining the effect of the present invention, the present invention by laminating a polyurethane sponge layer having a sound absorbing effect and a vibration damping effect on the surface, the sound absorption effect can be obtained without the use of a separate sound absorbing material to reduce the production cost, multi-layer Since the structure is made of an excellent vibration damping effect can be obtained even in a thin thickness, the weight is 50% or more lighter than the conventional vibration damping plate consisting only of asphalt sheet or rubber sheet, showing the weight reduction effect of the product using the same.
