Laminated decorative plate and method for the production thereof
The invention relates to a laminated decorative plate comprising a core made of a fiber or particle material, a resinous intermediate layer on at least one side of the core, a decorative layer not impregnated with resin and having a graphic image of the surface of the imitated material, and a transparent core layer, into which the relief-like reproduction of the surface structure of the imitated material is stamped. The intermediate layer is made of liquid glue, curable by pressure and/or heat, that is applied to the core.
1. A method for producing a laminated decorative plate, said method comprising a first production step of producing a semifinished product comprising the substeps of:
a) providing a plate made of a fiber or particle material;
b) coating the plate on at least one side with a layer of glue comprising a liquid glue curable by pressure and/or heat;
c) pressing a decorative layer not impregnated with resin onto the layer of glue simultaneously with said coating the plate with the layer of glue in a single working step;
wherein the steps a) to c) are performed as a lamination process to produce the semifinished product;
d) applying a cover layer comprising a melamine resin to the semifinished product to form a laminated product; and
e) pressing and heating the laminated product while forming a surface structure of the cover layer;
wherein substeps d) and e) are performed in a short-cycle press or in a continuous double belt press.
2. The method of claim 1 , wherein substeps d) and e) are performed in a short-cycle press or in a continuous double belt press using liquid melamine formaldehyde as a material for the cover layer.
3. The method of claim 1 , further comprising substep f) applying a counteracting layer to the plate made of a fiber or particle material if the decorative layer and the cover layer are present on only one side of the plate.
4. The method of claim 1 , further comprising substep f) applying a counteracting layer to the plate made of a fiber or particle material if the decorative layer is present on only one side of the plate.
5. The method of claim 3 , wherein the substeps a), b), c), and f) are performed as part of the first production step to produce the semifished product.
6. The method of claim 4 , wherein the substeps a), b), c), and f) are performed as part of the first production step to produce the semifinished product.
7. The method of claim 6 , wherein substeps d) and e) are performed in a short-cycle press or in a continuous double belt press using liquid melamine formaldehyde as a material for the cover layer.
8. The method of claim 2 , wherein the second production step including substeps d) and e) is performed as a separate step after the first production step including substeps a) to c) is complete.
9. The method of claim 1 , wherein the semifinished product is a storable semifinished product.
10. The method of claim 1 , wherein the semifinished product is stored before performing substeps d) and e).
