METHOD OF PRODUCING A BUILDING PANEL AND A BUILDING PANEL

A method of producing a building panel， including: providing a core， applying a balancing layer having a first moisture content on a first surface of the core， the balancing layer comprising a sheet impregnated with a thermosetting binder， applying a surface layer having a second moisture content on a second surface of the core， the surface layer comprising a thermosetting binder， adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing， and curing the surface layer and the balancing layer by applying heat and pressure. Also， a semi-finished product adapted to be cured for forming a building panel.

一种建筑板材（building panel）的制备方法，包括如下步骤：提供芯材（core）；在该芯材的第一表面施加具有第一含水率（moisture content）的平衡层（balancing layer），该平衡层由浸渍有热固性胶粘剂（thermosetting binder）的薄片构成；在该芯材的第二表面施加具有第二含水率的表层（surface layer），该表层包含热固性胶粘剂；在固化前调整平衡层的第一含水率，使得平衡层的第一含水率高于表层的第二含水率；通过施加热量与压力对表层与平衡层进行固化。此外，还提供一种经固化后可形成建筑板材的半成品（semi-finished product）。
