Definitions

  • the invention relates to a decorative laminate according to the preamble of claim 1, and to a method for producing such a laminate.
  • Laminates of this type are preferred in the manufacture of furniture and the expansion of buildings.
  • a core of resin-impregnated sodium kraft paper webs is formed, which are placed on top of one another in a stack.
  • a paper web impregnated with a synthetic resin is placed on top of this stack as the top one, which is colored or printed. The stack thus formed is then pressed at a predeterminable temperature and a corresponding pressure.
  • composite elements are produced that are used for furniture production.
  • a decorative laminate is glued onto the surface of a carrier.
  • Chipboard is preferably used as the carrier. It exists also the possibility to use beams made of an inorganic material such as concrete, cement, plaster or clay.
  • the surfaces of these decorative laminated panels are designed as glossy or special matt surfaces, as required.
  • the invention is therefore based on the object of providing a surface-protected decorative laminate, and of demonstrating a method with which such a decorative laminate can be produced.
  • a method for producing a decorative laminate is disclosed in claim 8.
  • the protective layer which is applied to the decorative laminate, can be further processed together with it up to a temperature of 200 ° C without the protective layer being damaged thereby.
  • the protective layer formed from a polyester or propylene film, which has a thickness between 0.05 and 0.2 mm.
  • the protective layer is releasably connected to the surface of the decorative laminate using a pressure sensitive adhesive.
  • the protective layer is applied to the decorative laminate plate after the core and decorative papers, which form the decorative laminate plate, are pressed.
  • the protective layer according to the invention allows the decorative laminated sheet to be shaped if it is used to form a.
  • Composite element is glued to a carrier that has rounded front edges.
  • the decorative laminated board equipped with the protective layer can be glued to chipboard supports using the cold and hot cycle method. After connecting the decorative laminate with a carrier to form a composite element, the protective layer remains on the surface of the decorative laminate. Only after the decorative laminated panel itself or the composite element with which the decorative laminated panel is glued is completely processed, is the protective layer detached from the surface. This is possible in a simple manner, since the protective layer is held on the surface of the decorative laminate with a pressure-sensitive adhesive based on natural rubber or acrylic resin. A detachment of the protective layer when pressing or gluing the decorative laminate with a carrier is excluded by using this pressure sensitive adhesive.
  • the protective layer has the advantage that the surface of the decorative laminate remains protected for as long as necessary, but the decor of the plate is always visible, which considerably facilitates further processing.
  • the surface of the decorative Laminated board also protected against dust and scratches during transport as well as against slipping and grinding marks. When the protective layer is removed, the formation of adhesive residues on the decorative layer is avoided since only the adhesives mentioned above are used.
  • the decorative laminate is explained in more detail below with reference to figures.
  • Fig.1 A protected decorative laminate
  • Fig. 2 the protected decorative laminate partially connected to a carrier
  • Fig. 3 a composite panel
  • Fig. 4 removing a protective layer.
  • Fig. 1 shows a decorative laminated sheet 1, which is formed by a core 2, a decorative paper web 3 and a protective layer 4.
  • the core 2 of the decorative laminated sheet 1 consists of several stacked sodium kraft paper webs (not shown here) which are impregnated with phenolic resin.
  • At least one decorative paper web 3 is arranged on this core 2.
  • This decorative paper web 3 is either colored with a color or printed.
  • the connection of the sodium kraft paper webs to one another to form the core 2 and the connection of the core 2 with the decorative paper web 3 is carried out in a known manner by pressing the stack of paper thus formed.
  • an aminoplast resin in particular a melamine resin.
  • the decorative laminated sheet 1 can be connected to the protective layer 4 according to the invention.
  • This protective layer 4 is preferably formed by a transparent plastic film which is made of polyester or polypropylene. Such a plastic film has the advantage that it is heat-resistant up to 200 ° C, which is a prerequisite for the further processing of the decorative laminate.
  • the protective layer 4 has a thickness between 0.05 and 0.2 mm.
  • the protective layer 4 made of polyester or polypropylene can be supplied up to a width of 2.40 m.
  • the film is wound on a roll so that any length can be removed. This offers the possibility of covering the entire surface of a decorative laminate, for example 5 m long and up to 2.40 m wide, with a coherent protective layer 4.
  • the protective layer 4 Since the protective layer 4 is designed to be heat-resistant, it can subsequently be betrayed with the decorative laminate 1.
  • the protective film 4 is releasably applied to the surface of the decorative paper web 3 with the aid of a pressure sensitive adhesive 5.
  • the protective layer 4 is then releasably applied to the transparent cellulose web (not shown here) with the aid of the pressure sensitive adhesive 5.
  • the decorative laminate plate 1 shown can be permanently connected to a carrier 6A to form a composite element 6. This can be made from an organic or inorganic material.
  • the carrier 6A can be formed by stacking and pressing resin-impregnated paper webs.
  • a particle board is preferably used as the carrier 6A.
  • a carrier 6A can also be used to form a composite element, which carrier is made of cement, concrete or a foam.
  • the carrier 6A shown in FIG. 2 has a rounded front edge 3R.
  • the decorative laminate 1 shown in FIG. 1 is permanently bonded to the surface of the carrier 6A.
  • the decorative laminated sheet 1 provided with the protective layer 4 can be shaped with the aid of heat so that it also completely covers the rounded front edge 3R of the carrier 6A.
  • the decorative laminate 1 is reshaped with the aid of heat and pressure rollers with which the decorative laminate 1 is bent in accordance with the shape of the rounded front edge 3R.
  • the permanent connection of the decorative laminate 1 to the carrier 3 is done by gluing.
  • a finished composite element 6 is shown in FIG. 3.
  • the entire surface of the carrier 6A, including the rounded front edge 3R, is covered by the decorative laminate plate 1.
  • the protective layer 4 according to the invention is held so firmly on the surface of the decorative laminate using the pressure-sensitive adhesive 5 that it is neither glued nor the protective layer 4 comes off when pressed with the carrier 6A.
  • the finished composite element 6 can now also be mechanically processed, in particular further processed into a piece of furniture or a wall covering. It can also be sawn into parts, provided with bores or millings without the protective layer 4 being detached.
  • the protective layer 4 can be detached from the surface of the decorative laminate 1 without adhesive residues. By the use of.
  • the color of the decorative paper web 3 is not attacked by pressure-sensitive adhesives based on natural rubber or acrylic resin.

Abstract

Plaque stratifiée décorative (1) comportant au moins une bande de papier pour imprégnation (3) et une âme (2) formée de plusieurs bandes de papier imprégné. L'invention a pour objet de protéger la surface de ladite plaque (1) de manière à éviter son altération par la déformation thermique et les actions mécaniques, au moins jusqu'à l'achèvement de son traitement complet. A cet effet, on applique de manière amovible une couche protectrice (4) sur la surface de la plaque stratifiée décorative (1). Cette couche protectrice (4) est produite à partir d'un film plastique transparent résistant à la chaleur.
