Title: A method for manufacturing a laminate comprising a stack of composite fibre boards
The present invention relates to a method for manufacturing a laminate comprising a stack of composite fibre boards. The present invention also relates to such a laminate as well as to its use in interior and exterior applications.
European patent application EP 3 767 055 relates to a water impervious wall panel system comprising an intermediate first waterproof wall panel and an end second waterproof wall panel, wherein the intermediate first waterproof wall panel and the end second waterproof wall panel each comprise a core of wood plastics composite. The core is a wood plastics composite foamed board composed of PVC and wood fibre and the intermediate first waterproof wall panel and the end second waterproof wall panel each further comprise a laminate adhesively attached to the core, wherein the laminate is a high pressure laminate, and the adhesive is a polyurethane adhesive.
US 2019/308392 relates to a process for manufacturing a composite board comprising mixing bast fibers and/or glass fibers with plastic fibers thereby forming a fiber layer, and thermoforming said fiber layer into a nonwoven composite material layer, wherein said thermoforming comprises impregnating the fiber layer under vacuum conditions with liquid thermoset and heating.
US 2017/320309 relates to a method of making a composite panel configured for use with a flooring assembly of a trailer, the method comprising: providing a wood substrate, making an uncured fiber-reinforced coating, applying the uncured fiber- reinforced coating onto a surface of the wood substrate to form a composite assembly; and curing the uncured composite assembly, thereby coupling a cured fiber-reinforced coating to the wood substrate, wherein making the fiber-reinforced coating further comprises the step of applying constant pressure of between 1 and 2,4 bar to the composite assembly.
WO 2012/009514 relates to a method for forming a biolaminate structure, the method comprising providing a first paper layer, providing a biobased polymer film layer, providing a second paper layer, and at least partially saturating the first paper layer and the second paper layer with a biobased polymer, wherein saturation may be from the biobased polymer of the biobased polymer film layer or may be from an additional biobased polymer source, fusing the first paper layer, the biobased polymer film layer, and the second paper layer under means of heat and pressure to form the biolaminate structure, wherein fusing is done at a pressure between about 1.4 bar and about 103,4 bar and temperatures range from 154 °C to 204 °C.
US 2015/151449 relates to a method for producing a lignocellulosic composite, the method comprising providing an aqueous adhesive material comprising a magnesium oxychloride compound and a proteinaceous material, applying the aqueous adhesive material to a lignocellulosic substrate, curing the aqueous adhesive material, wherein curing the aqueous adhesive material comprises applying pressure of between about 0,7 bar and 69 bar at a temperature of between about 50°C and 250°C.
WO 99/66119 relates to a method of manufacturing an Arundo donax composite panel, the method comprising comminuting Arundo donax into particles of a size distribution suitable for use as furnish in a composite panel, mixing the particles with a binder to provide a binder-particle mixture, and consolidating the binder-particle mixture into a composite panel. When MDI resin is used, the press is typically operated at a temperature in the range of 160-170°C, and under pressure of between 34,5 — 41,4 bar (maximum) during the closing cycle and about 7 bar during the curing cycle.
