Composite material laminated board and preparation method thereof
The invention relates to a composite material laminated board and a preparation method thereof, and belongs to the technical field of building decoration materials. The structure comprises impregnatedpaper positioned on the upper layer, an intermediate layer sheet positioned in the middle and a substrate positioned on the lower layer, wherein a PUR hot melt adhesive layer is arranged between theintermediate layer sheet and the base plate, the impregnated paper is decorative paper impregnated by thermosetting resin, the intermediate layer sheet is a fiber sheet which can be respectively permeated by the thermosetting resin and PUR hot melt adhesive, and the base plate is a sheet-shaped plate of which the surface cannot be directly bonded with the thermosetting resin. According to the invention, fibers of the intermediate layer are used as a medium to form two cured layers which are respectively bonded with two materials which cannot be bonded with each other. The preparation process adopts a two-step production method of firstly preparing the composite substrate of the intermediate layer thin plate and the substrate, and then carrying out hot-pressing compounding on the compositesubstrate and gum dipping to form the composite laminated board. Therefore, the obtained composite laminated board has the advantages of boiling resistance, water soaking resistance, heat resistance,no layering and long service life.
本发明涉及一种复合材料层压板及其制备方法，属于建筑装饰材料技术领域。本发明的结构包括位于上层的浸胶纸、位于中间的中介层薄片和位于下层的基板，所述中介层薄片与基板之间具有PUR热熔胶层，所述浸胶纸是由热固性树脂浸渍的装饰纸，所述中介层薄片是可分别被热固性树脂和PUR热熔胶渗透的纤维薄片，所述基板是其表面不能与热固性树脂直接粘接的片状板材。本发明利用中介层的纤维作为媒介形成两种固化层，分别粘合两种无法相互粘接的材料。制备过程采用先制备中介层薄板+基板复合基板，然后复合基板与浸胶中热压复合形成该复合层压板的两步生产方法。所得复合层压板具有耐水煮、耐水泡、耐热、不分层和使用寿命长的优点。
