본 출원은 액체 에폭시 수지와 폴리염화비닐 수지 및/또는 아크릴 수지 분말의 조합물에 기초한 펌핑 가능한 열발포 충전제 조성물에 관한 것이다. 이러한 펌핑 가능한 충전제 재료는 종래의 주입 장비를 이용해서 필요에 따라 적용될 수 있고 유성 금속 기재에 대한 양호한 물리적 강도, 높은 팽창률 및 우수한 접착성을 가진 발포물을 제공하기 위하여 팽창될 수 있다는 이점을 제공한다. 본 발명은 또한 제시된 방법으로 얻어질 수 있는 차량 부품뿐만 아니라 펌핑 가능한 열발포 충전제 조성물로 폐쇄된 공간을 충전시키기 위한 방법을 기재한다.

    The present application is directed to pumpable thermally foaming filler compositions based on combinations of a liquid epoxy resin and a polyvinyl chloride resin and/or an acrylic resin powder. These pumpable filler materials provide the advantage that they can be applied as needed using conventional injection equipment and can be expanded to provide foam with good physical strength, high expansion and excellent adhesion on oiled metal substrates. The present invention further describes methods for filling closed spaces with the pumpable thermally foaming filler composition as well as vehicle parts which are obtainable with the indicated methods.
