连续生产三明治复合材料元素的方法

METHOD FOR CONTINUOUSLY PRODUCING A SANDWICH COMPOSITE ELEMENTS
摘要：
In order to provide sandwich composite elements (100) having an improved fire protection behavior, the invention relates to a method for continuously producing sandwich composite elements (100) having a lower cover layer (10), an upper cover layer (11), and a polyurethane hard-foam core body (12) introduced between the cover layers (10, 11), wherein a double belt conveyor system (18) having a lower conveyor belt (19) and an upper conveyor belt (20) is provided and wherein the lower cover layer (10) and the upper cover layer (11) continuously run in between the conveyor belts (19, 20), wherein at least one glass-fiber mat (13) continuously runs in between the cover layers (10, 11) and is arranged adjacent to the inside or at least one of the cover layers (10, 11) and wherein a subsequently foaming reaction mixture (14) is applied to at least one inside of the cover Layers (10, 11) and/or to the glass fiber mat (13) in order to form the polyurethane hard-foam core body (12).
摘要（中）：

为了提供具有改进的防火性能的夹层复合材料（100），本发明涉及一种用于连续生产具有下覆盖层（10），上覆盖层（11）和 引入到所述覆盖层（10,11）之间的聚氨酯硬泡沫芯体（12），其中提供具有下传送带（19）和上输送带（20）的双带输送机系统（18），并且其中 所述下覆盖层（10）和所述上覆盖层（11）在所述输送带（19,20）之间连续地延伸，其中至少一个玻璃纤维垫（13）在所述覆盖层（10,11）之间连续延伸 ）并且被布置成与所述覆盖层（10,11）中的内部或至少一个覆盖层相邻，并且其中随后的发泡反应混合物（14）被施加到覆盖层的至少一个内部层（10,11）和/或 以形成聚氨酯硬质泡沫芯体（12）。
