As a damping sealer containing a resin in a specific ratio, it is not easy to apply the existing automation equipment of asphalt-based, low adhesiveness, improves the problem of oil leakage during high temperature curing, and is easy to apply using the automation equipment, in particular, using the present invention. The present invention relates to a vibration damping sealer composition having an excellent adhesion performance when the vibration damping sheet is attached to an automobile part.

도로를 달리는 자동차에 있어 진동과 소음은 줄여나가야 하는 과제로 오랫동안 관심을 받아온 분야이다. 이러한 진동과 소음을 줄여나가기 위해 타이어, 쇼바, 및 차체구조 등의 다양한 분야에서 연구가 진행되어 왔으며 꾸준히 진행되고 있다. 이러한 분야 중 진동 제어 및 방음 효과를 부여하는 것이 제진 실러이며, 기존 자동차에 시트 형태로 장착되어 자동차내 도장 오븐의 열에 의해 열융착됨으로서 진동 및 방음성능을 발휘하게 되는 것이다. 이러한 제품으로 가장 많 이 사용되고 있는 것이 아스팔트 타입의 제진 실러이다. Vibration and noise in road vehicles have long been a concern as a challenge to reduce. In order to reduce such vibration and noise, researches have been conducted in various fields such as tires, shovars, and body structures, and are being steadily progressed. Vibration control and soundproofing effect in this field is to provide a vibration damping sealer, and is mounted on the existing vehicle in the form of a sheet is heat-sealed by the heat of the paint oven in the car to exhibit the vibration and soundproofing performance. The most popular type of these products is the asphalt type vibration damper.

상기 아스팔트 타입의 제진 실러의 주성분은 아스팔트피치로서 석유의 부산물 중 하나이며, 아스팔트 피치 시트는 점착성이 매우 강하기 때문에 시트표면 위에 수작업 시 장갑이나 손에 탈부착 시 오염을 방지하기 위해 탈크로 코팅시켜 이를 억제시키고 있다. 그러나 코팅된 탈크는 수작업 시 작업장내 분진으로 대기오염을 유발시키고 작업자의 인체에 흡수되며, 차량바디에 부착되어 오염을 유발시킨다. 또한 아스팔트피치는 도장공정 중 고온 오븐통과 시 유분이 발생하여 페인트 도장 시 문제점이 발생한다.The main component of the asphalt type vibration damping sealer is one of the by-products of petroleum as an asphalt pitch. As the asphalt pitch sheet is very sticky, it is suppressed by coating with talc to prevent contamination when attaching to gloves or hands when the manual work is applied on the sheet surface. I'm making it. However, the coated talc causes air pollution by the dust in the workplace during work and is absorbed by the human body of the worker, and is attached to the vehicle body to cause pollution. In addition, asphalt pitch is generated during the coating process during the high temperature oven barrel oil during the painting process.

이에, 본 발명자들은 제진 실러의 제진성, 방음성, 차음성 및 철판 강성 등 기계적 물성을 향상과 자동화 기기의 적용불가, 낮은 접착성, 고온 경화 시 유분이 유출되는 문제점을 개선시키고자 한다.Accordingly, the present inventors aim to improve the mechanical properties such as vibration damping, soundproofing, sound insulation, and steel sheet stiffness of the vibration damping sealer, and the problem that oil is leaked during application of an automated device, low adhesion, and high temperature curing.

그 결과 특정의 분자량을 가진 에폭시 수지와 가소제, 충전제, 발포제, 수분흡수제, 안정제, 및 점착부여제를 용융 혼합하여 조성물을 제조함으로써 본 발명을 완성하였다.As a result, the present invention was completed by melting and mixing an epoxy resin having a specific molecular weight with a plasticizer, a filler, a foaming agent, a moisture absorbent, a stabilizer, and a tackifier to prepare a composition.

따라서 본 발명은, 낮은 접착성, 고온 경화 시 유분이 유출되는 문제점이 개선되며 분무식으로 자동화 기기에 사용이 가능한 제진 실러 조성물을 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a damping sealer composition which can be used in an automated device by spraying and improving the problem of low adhesion, oil leakage during high temperature curing.
