- It may also be a panel comprising several identical or different layers of cellulosic material (s). We often speak in this case of sandwich panel.
- the panel can also comprise at least one layer of an elastomeric material or of a foam whose function is to improve the sound insulation of the panel. It can also include at least one counterbalancing layer whose function is to mechanically stabilize the panel to avoid buckling or deformation of the panel.
- an intermediate layer of an adhesive is provided between them, generally of thin thickness.
- the glue is often a thermosetting glue, for example of the phenolic or melamine type. examples of panels
- a decorative layer composed of a tinted cellulose film and a cellulose film impregnated with melamine and having a silica filler.
- a sandwich panel comprises in order a layer of paper, a layer of wood and possibly a decorative layer or else a layer of paper and a decorative layer.
- Another example of a sandwich panel optionally includes, in order, a decorative layer, a layer of wood, a layer of paper, a layer of wood and possibly a decorative layer.
- Another example of a sandwich panel comprises, in order, a decorative layer, a layer of wood and a decorative layer.
- the multilayer film is applied to the wood layer or to the decorative layer.
- the paper layer can also be replaced by a stack of several layers of paper.
- the paper used is kraft paper.
- the decorative layer can be a single color or have a printed pattern. It can be one or more cellulose film (s) or printed paper. It can also be a layer of thermosetting adhesive loaded with pigments. Adhesion between the layers is ensured by a layer of glue.
- the adhesive is a thermosetting adhesive of the phenolic or melamine type.
- the BAQ + ® panel from PRODEMA is described on the website of this company as being a high density panel consisting of a core of cellulose fibers impregnated with thermosetting phenolic resins and a layer of natural wood.
- the MAD ® panel from PRODEMA is described as being a panel composed of a plywood core impregnated with thermosetting phenolic resins and a layer of natural wood.
- the PARKLEX ® 1000 panel from the company GUREA is described on the website of this company as being a high density wooden laminated panel formed inside by wood or paper fibers treated with thermoset phenolic resins and very strongly pressed at high temperatures and a layer of natural wood. The multilayer film is applied against the layer of wood.
- the multilayer film of the invention is used to protect a (ligno) cellulosic material such as wood, cardboard or paper.
- the adhesive layer (III) is arranged on the side of the cellulosic (ligno) material.
- the adhesion of the film is reinforced if it comes into contact with a thermosetting adhesive placed on the surface or in the mass of the (ligno) cellulosic material.
- a thermosetting adhesive is placed between the (ligno) cellulosic material and the film.
- the glue is placed on the surface of the material in the form of a layer or else in the form of spots of glue in several places of the material.
- the (ligno) cellulosic material is therefore covered in whole or part of its surface by thermosetting glue.
- the adhesive may for example be a phenolic adhesive, for example phenol-formaldehyde, or melamine or urea-formaldehyde.
- the glue can also be present in the mass of the (ligno) cellulosic material, as for example in the case of an agglomerated panel.
- the invention also relates to a multilayer structure comprising at least one layer of a cellulosic (ligno) material and the film of the invention disposed against this layer, the adhesive layer (III) being disposed on the side of the material (ligno) cellulosic. More particularly, the film can be applied to a panel of which at least one of the two external faces consists of a (ligno) cellulosic material. The adhesive layer (III) is arranged on the side of at least one of the two external faces of (ligno) cellulosic material. The invention also relates to such a panel. advantages of the multilayer film
- the cellulosic (ligno) material is protected by the multilayer film of the invention. This provides protection against UV rays, chemicals, scratches, atmospheric agents (humidity, salt spray, ...), fungi and molds or even graffiti.
- the film ensures color and appearance stability over time.
- the film can be applied by hot compression. The compression is carried out under a pressure generally between 2 and 30 MPa and hot at a temperature generally between 100 and 16O 0 C.
- ALTUGLAS ® BS8 PMMA society INTERNATIONAL ALTUGLAS MVI of 4.5 cm 3/10 min (23O 0 C, 3.8 kg) in bead form containing as comonomer, methyl acrylate, up to 6% by weight. This PMMA does not contain a shock modifier.
- ALTUGLAS ® PRD 510 A PMMA PRD 510 A is a copolymer of methyl methacrylate and ethyl acrylate (25% by weight). Its MFI is 5 g / 10 minutes at 230 ° C. under 3.8 kg.
- ALTUGLAS ® V825T PMMA homopolymer from the company ALTUGLAS INTERNATIONAL of melt-flow 5.5 g / 10 min (230 ° C., 3.8 kg) in the form of granules. This PMMA is not a functional PMMA.
- ALTUGLAS ® HT121 marketed by ALTUGLAS INTERNATIONAL. This product contains about 4.5% by weight of methacrylic acid or anhydride from methacrylic acid. It has a melt-index of 2 g / 10 min (230 ° C., 3.8 kg).
- TINUVIN ® 234 UV absorber of hydroxyphenyl benzotriazole type from the company CIBA SPECIALTY CHEMICALS.
- KYNAR ® 740 Homopolymer PVDF from the company ARKEMA from MFI 13 g / 10 minutes at 12.5 kg at 230 ° C.
- Example 1 (according to the invention)
- a three-layer film is prepared with the following layers from the inside to the outside of the bubble:
- the film obtained is very transparent and has excellent resistance to external aging as well as excellent chemical resistance.
- This film is placed at the bottom of a mold.
- the three-layer film has excellent adhesion just after curing, it is not possible to peel this film from the surface of the crosslinked phenolic resin.
- This plate is cut on its four edges in order to have perfectly straight plate sides and dimensions of 5 cm x 5 cm. This plate is then introduced into a boiling water bath for 2 hours. After this treatment, there is no bleaching or detachment.
- Example 2 comparative
- the film obtained is very transparent and has excellent resistance to external aging as well as excellent chemical resistance. This film is placed at the bottom of a mold.
- On the film on the side of PMMA ALTUGLAS ® V825 T 2 layers of Kraft paper coated with phenolic resin of the TPS type color from COVERIGHT are deposited, these layers are laid on a 200 ⁇ m thick wooden strip previously coated.
- the three-layer film has good adhesion just after curing, it is not possible to peel this film from the surface of the crosslinked phenolic resin.
- This plate is cut on its four edges in order to have perfectly straight plate sides and dimensions of 5 cm x 5 cm. This plate is then introduced into a boiling water bath for 2 hours, after this treatment the appearance of the plate is inspected. There is a bleaching as well as a separation of the edges of the film.
