Manufacturing method for multi-layer floor panel
In a first pressing stage making up the preliminary pressing, the glue layer forming the single multilayer flooring panel (1) is pressed for a time of between 5 seconds and 50 seconds until a physical local bonding of the layers is obtained, allowing the position of the solid wood sheet making up the top layer (4) to be seated on the core composite layer (2) covered with the adhesive. In a next stage, a stack is formed from a plurality of flooring panels (1) so pressed, after which the stack of preliminarily pressed flooring panels (1) is subjected to a second pressing stage constituting the main pressing for a time of more than 300 seconds until an adhesive bond of desired durability and strength is obtained, the adhesive (3) applied to the core composite layer (2) is a reactive hot melt polyurethane adhesive.
在构成初步压制的第一压制阶段中，将形成单个多层地板面板(1)的胶合层压制介于5秒与50秒之间的时间，直到获得层的物理局部的结合，从而允许确定构成顶层(4)的实木片材安置在覆盖有粘合剂的芯复合层(2)上的位置。在下一阶段中，由如此压制的多个地板面板(1)形成堆叠件，之后，初步压制的地板面板(1)的所述堆叠件经受构成主压制的第二压制阶段超过300秒的时间，直到获得所需的耐久性和强度的粘合剂结合，其中，施加至芯复合层(2)的粘合剂(3)是反应性热熔聚氨酯粘合剂。
