Description

  • The invention relates to a method to coat a substrate with a melamine-formaldehyde resin so as to obtain good mechanical properties of the final coating. Good mechanical properties are for example required when the coated substrate is afterwards subjected to post-forming. The invention also relates to the coated substrate with good mechanical properties, appearance and durability, to the melamine-formaldehyde resin and to the melamine.
  • In US-3.730.828 a post-formable substrate is coated with a decorative barrier sheet consisting of ordinary α-cellulose wood fibre impregnated with a fully cured, unplasticized melamine-formaldehyde resin with a narrow range for the mole ratio between the formaldehyde and the melamine. A laminate is prepared by assembling various layers of kraft paper and a top, barrier, sheet with the unplasticized melamine-formaldehyde resin. All these carrier layers are formed into a laminate by placing the stacked layers in a laminating press under high pressure and at high temperatures during a certain amount of time. A disadvantage of the obtained laminates is that they cannot be bent into complex shapes along two (or more) mutually intersecting axis without breaking and/or cracking.
  • In WO 99/13000, a laminar prepreg is described which prepreg comprises one or more layers of a laminar carrier that is impregnated with an as yet uncured resin. The carrier is a laminar porous polymer. The laminar porous polymer may be a non-woven laminar polymer, a laminar open polymer foam or a microporous membrane. The laminar porous polymer is impregnated with the resin upon which drying is necessary at a temperature between 100 and 160 °C. The so obtained carrier is stacked after drying. The prepreg can subsequently be processed into a shaped final product by first deforming the prepreg and then curing the shaped intermediate product at elevated temperature or by combining the deformation and the curing step in one step. A disadvantage of the prepreg according to WO 99/13000 is that the laminar prepreg comprises at least two components that first must be obtained in separate steps: a laminar porous polymer and an (at the prepreg stage) uncured resin.
  • In WO00/53666 a prepreg is described that contains one or more layers of a porous carrier sheet, which porous carrier sheet has been impregnated with an as yet uncured resin, the carrier containing a meltable polymer mixed with cellulose or regenerated cellulose or mixtures there from. In WO 00/53667 a prepreg is described that contains one or more layers of a porous carrier sheet, which porous carrier sheet has been impregnated with an as yet uncured resin, the carrier being a porous carrier on the basis of wholly or partly regenerated cellulose. In WO 00/53688 a prepreg is described that contains one or more layers of a porous carrier sheet, which porous carrier sheet contains at least one fibrous cellulose ester. A disadvantage of these systems that are based on a porous polymer as a carrier and an (at the prepreg stage) uncured resin is that at least two components are necessary in the initial stages of the prepreg stage.
  • It is an object of the invention to overcome the above-mentioned disadvantages and to make available a method to coat a substrate with a melamine-formaldehyde resin which is less complicated than the methods in the prior art and still results in a coated substrate with good mechanical properties.
  • The object is reached by a method that comprises the following steps:
    • a. Applying a layer of powderous melamine-formaldehyde A resin to a substrate,
    • b. Melting the melamine-formaldehyde resin by IR- or NIR- radiation,
    • c. Optionally applying an ink, dye solution or pigment dispersion to the with molten melamine-formaldehyde resin coated substrate,
    • d. Optionally applying a layer of melamine-formaldehyde resin B to the coated substrate from step b) or c),
    • e. Optionally heating the coated substrate from the previous steps in a laminating press for a certain amount of time,
    • f. Increasing the pressure in the laminating press and keeping the laminate under pressure for a certain amount of time.
  • The method according to the invention makes it superfluous to install a separate drying section for the impregnated porous polymer. Therefore the space and apparatus necessary for the process of coating a substrate can be reduced compared to the prior art. Additionally as no drying of the impregnated porous polymer at increased temperatures is necessary in the present invention the method is advantageous from an economical and ecological point of view. Another advantage of the method according to the invention is that separate stacking of the various layers is not necessary anymore. A further advantage of the method according to the present invention is that the melamine-formaldehyde coating is applied directly onto the substrate that needs to be coated for further use, as for example worktops cupboards and fronts of kitchen cupboards. In this method a separate "prepreg stage" is absent.
  • In step a) of the method according to the invention a melamine-formaldehyde resin in powder form is applied onto the surface of the substrate so as to form a layer. With powder is here and hereinafter meant a solid consisting of small particles generally with a particle size smaller than 250 µm, preferably below 100 µm. With very large particles an even distribution over the surface of the substrate is difficult, further the resolution of the applied pattern that is formed by the ink, dye solution or pigment dispersion in step c) is worse than when smaller particles are used. The thickness of the layer is not particularly critical and can be chosen between wide ranges, for example between 20 and 500 µm. A preferred layer has a thickness between 50 and 250 µm. A balance should be found between a thick layer that is advantageous for hiding imperfections in the substrate surface, and a thin layer that is more advantageous for post-forming. It is known to the man skilled in the art how powders can be obtained from melamine-formaldehyde resins. Reference can for example be made to "Kunststoff Handbuch, 10-Duroplaste" by W. Becker, D. Braun, 1988 Carl Hanser Verlag; more specifically to the chapter "Melaminharze", page 41 and further.
  • With melamine-formaldehyde resin A is meant a resin with as main building blocks melamine and formaldehyde. The melamine-formaldehyde resin in A can additionally contain other building blocks, for example urea and flexibilizers as for example diethylene glycol and sugars.
  • The melamine-formaldehyde resin that is used in step a) should have a glass transition temperature (Tg) high enough to be stable at room temperature as a powder for an extended period of time. In case the Tg is not high enough the resin particles will coagulate and the powder will lose its form and stability. Suitable values for the Tg are at least 30 °C, preferably 40 °C, with more preference between 60 and 90 °C. The Tg should be below the temperature at which steps e) and/or f) in the method are performed; as when the Tg is higher than the temperature in step e) the resin will not melt and thus it will not flow. Generally the Tg should therefore be below 140 °C, preferably lower than 120 °C.
  • The melamine-formaldehyde resin A should advantageously be able to form a non-porous layer after heating and curing in step f) so as to prevent diffraction of light by included components as for example water or air. Diffraction would lead to a "blurred" pattern. This requirement can advantageously be reached by a formaldehyde-melamine ratio in the resin A between 1 and 3 (on mol basis). Optionally the melamine-formaldehyde resin A can be partially crosslinked before it is applied onto the substrate. Depending on the precise composition of the melamine-formaldehyde resin A, the rate of pre-crosslinking is determined by the ability to flow. When the pre-crosslinking has proceeded too far, the resin A will not flow sufficiently and it will be impossible to remove all included components such as for example air by pressing. The man skilled in the art can easily determine the desired rate of pre-crosslinking.
  • The resin A in step a) can additionally contain a pigment. In that case the coating that is finally obtained has a more or less uniform colour, with no special recognizable pattern. In case that such a uniform coloured layer is required the optional steps c) and d) can be left out but it may still be desirable to add in step d) a transparent topcoat layer on top of layer A to obtain a better appearance and durability. When a décor pattern in the coating is desired steps c) and d) are required.
  • The resin should display such a combination of properties that the resin after the melting in step b) forms a porous layer. When melting the resin particles, they flow towards each other. Depending on the circumstances during the flow phase, and given enough time, the molten particles will finally touch each other completely, thereby giving rise to a non-porous layer. However for the optional step c) it is necessary to have a layer that is still porous to some level. To keep the layer porous, the temperature during the flow-phase shouldn't be too high when the time for the flow phase is moderate. When the time available for flowing is only short, the temperature should be higher. Therefore a balance should be found between these parameters that determine the amount of flow. The man skilled in the art can easily determine the suitable conditions by routine experimentation.
  • The kind of substrate depends on the final use of the coated substrate and can be for example wood or wood-based material, paper, metal, glass or plastic. Examples of wood-based materials are MDF (Medium Density Fibreboard) or HDF (High Density Fibreboard), OSB (oriented strand board), particle board, plywood. The coated substrates can be used in a large number of applications, for example serving trays, washing-up basins, crockery, doors, kitchen worktops, furniture and wall panels, kitchen cupboards, window frames, laminated flooring.
  • In step b) of the method according to the invention the applied resin is being molten by IR- or NIR-radiation and can be chosen freely. It is preferred to use IR-radiation for thinner layers, for example 0-5 µm, NIR is preferably used for thicker layers for example up to 0.5 mm to ensure a favourable temperature prophile across the layer thickness. The duration of the radiation depends on the intensity of the radiation and the characteristics of the resin to be molten. The duration and intensity of the radiation should be such that a coherent layer is obtained, that still has a maximum porosity. This can easily be determined by routine experimentation by the man skilled in the art.
  • In step c) a décor pattern is applied to the porous layer A. The coloured material for forming such a pattern can be an ink, or a dye solution in water, solvent or in a polymer, or a pigment dispersion in water, solvent or in a polymer. The coloured material can be a solid or a liquid and can be applied by any kind of imaging technique, such as off-set and roller printing, ink-jet printing, heat-transfer printing, toner printing etc as described in "Handbook of Imaging Materials" (Arthur S. Diamond ed., Marcel Dekker, 1991).
  • In step d) a layer of melamine-formaldehyde resin B is applied to the coated substrate obtained after step b) or c). The melamine-formaldehyde resin B can be a liquid or in powder form. It is preferred to use a powderous melamine-formaldehyde resin B as in the case that it is a liquid the risk exists that the liquid will penetrate into the porous layer obtained after step b). The nature of the melamine-formaldehyde resin B can vary, depending on the required properties of the final coating. Preferably the resin B is in powderous form with a Tg in the same ranges as indicated for resin A, it preferably has a good flow at the temperature in steps e) and f) and cures into a transparent and scratch-resistant topcoat so as to make the underlying pattern visible, while also giving an excellent adhesion with the underlying layer by co-reaction in the final curing steps e) and f). In order to protect the underlying layer(s) from environmental influences and degradation, stabilizers for example Hindered Amine Light Stabilizers (HALS), and UV absorbers can be added to resin B. In addition, to ensure a better scratch resistance inorganic fillers for example clay, silica and corundum can be added to the resin. Preferably, for the purpose of maintaining the optical transparency, filler particles of less than 300 nanometer are used.
  • Subsequently the coated substrate from step d) is heated in a laminating press for a certain amount of time. The absolute duration is not critical. Time and temperature are interdependent, it means that the result obtained counts but that the result can be obtained either by a high temperature and a relatively short time or by a somewhat lower temperature and a longer time. For example the time can vary between 1 and 3 minutes and the temperature can than vary between 100 and 140 °C. The balance between time and temperature should be chosen so as to result in a level of cure to give acceptable properties regarding the gloss and Kiton test for laminates.
  • Advantageously the layers A and B are pre-cured with heat before applying pressure. This pre-curing is done to prevent flow and absorption of the molten resin into the substrate, under the influence of pressure, which would blur the image. For this purpose, the laminating press can for example been pre-heated before the coated substrate is fed to it. Alternatively the coated substrate can be pre-treated in a separate step so as to result in a partially cured coating. Both alternatives result in a better resolution of the pattern when a pigment, ink or dye is used in step c). It has also been found that the pre-heating or pre-treating results in a better topcoat.
  • In step f) the pre-cured coated substrate is subjected to increased pressure and kept under pressure for a certain amount of time. The time and pressure are as generally used in the field of laminates.
  • The invention also relates to the melamine-formaldehyde coated substrate that is obtained with the method according to the invention It has good mechanical properties. Depending on its further use, requirements need to be met in view of for example scratch resistance, flexibility, durability, chemical resistance, abrasion resistance, cold check (that means the crack resistance at a sharp temperature change). Depending on its final use some of the above-mentioned properties are more important than others. Also depending on its further use of the coated substrate, requirements need sometimes to be met in regard of its appearance.
  • The melamine-formaldehyde coated substrate that is obtained according to the invention shows improved adhesion between the coating layer and the substrate compared to the prior art laminates in which first a prepreg is made where after the prepreg is pressed onto the substrate.
  • The invention further relates to the use of the melamine-formaldehyde coated substrate that is obtained according to the method of the invention in a post-forming process without structural damage to the coating.
  • The invention also relates to the use of a melamine-formaldehyde resin with a formaldehyde to melamine ratio between 1-3 (on mol basis) in a method according to the invention.
