Abstract

Abstract Translated from German Bei einer schalldämmenden Verbundplatte aus zwei metallischen Deckblechen (1) besteht der Gummikern (2) aus gebundenem Gummischrott oder Gummigranulat, wodurch sowohl die Wärme- als auch die Schalldämmung merklich erhöht werden. In the case of a sound-absorbing composite panel consisting of two metallic cover sheets (1), the rubber core (2) consists of bound rubber scrap or rubber granulate, which noticeably increases both thermal and acoustic insulation. In einfacher Weise wird diese Verbundplatte dadurch hergestellt, daß die beschichteten Deckbleche (1) und Schmelzkleberfolien (3) auf den Gummischrottkern (2) aufgelegt werden, worauf dieser Verbund unter Erhitzung einer fortschreitenden Flächenpressung unterworfen wird. This composite panel is produced in a simple manner in that the coated cover sheets (1) and hot-melt adhesive films (3) are placed on the rubber scrap core (2), whereupon this composite is subjected to a progressive surface pressure with heating.
