Provided is a dash insulation pad for a vehicle, which is manufactured by adding foam capsules when a sound insulation sheet is manufactured so that the sound insulation sheet which is heavy is lightened, to obtain required performance thereof, which is equal to or higher than that of a conventional sound insulation sheet. Particularly, provided is a dash insulation pad for a vehicle, in which foam capsules individually expanding to form air pores are added to and foamed in a sound insulation sheet so that cells in the sound insulation sheet are independently and uniformly formed even without using chemical gas and the like so that the dash insulation pad is uniformly formed and lightened. Accordingly, provided is a dash insulation pad for a vehicle, in which a sound insulation sheet has reduced specific gravity compared to a conventional sound insulation sheet, and obtains elongation performance that is similar thereto, thereby being lightened, and which can obtain equivalent sound insulation performance compared to weight reduction in a frequency band of 500-3 kHz.

    차음 시트를 제작할 때 발포 캡슐을 첨가하여 대시 인슐레이션 패드를 제작하므로, 중량이 많이 나가는 차음 시트를 경량화하면서도 기존 차음 시트와 같거나 높은 요구 성능을 갖도록 한 자동차용 대시 인슐레이션 패드를 제공한다. 특히, 개별적으로 팽창하여 기공을 형성하는 발포 캡슐을 차음 시트에 첨가하여 발포 성형하므로, 화학가스 등을 사용하지 않으면서도 차음 시트 내에 균일하게 독립적으로 셀을 형성하여 균일하면서도 경량화할 수 있게 한 자동차용 대시 인슐레이션 패드를 제공한다. 이에, 기존 차음 시트와 비교하여 비중을 줄이면서도 유사한 신율 성능을 얻어 경량화할 수 있을 뿐만 아니라 500~3㎑ 영역의 주파수 대역에서 경량화 대비 동등한 차음성능을 얻을 수 있는 자동차용 대시 인슐레이션 패드를 제공한다.
