Definitions
- the present invention relates to solid particles coated with melamine resin, the hardness of the solid particles according to Mohs being at least 7.
- the invention relates to aqueous impregnating resin solutions which contain these coated solid particles and other substances, as are customary in solutions which are suitable for the production of overlay and decorative films, the overlay and decorative films themselves produced therewith, wood-based materials which contain them Films are coated and processes for the production of these coated solid particles, aqueous solutions, films and coated wood-based materials.
- wood-based materials can be given a decorative surface by the application of laminates consisting of one or more superimposed papers impregnated with melamine resins, which also increases the sensitivity of the wood-based material surface to mechanical stresses how abrasion, scratching and water vapor are reduced (cf. Ullmanns Encyklopadie der Technische Chemie, 4th edition, volume 7, pp. 417 and 418).
- the top layer is often formed by a colored or printed decorative paper, or the top layer is still provided with a transparent overlay paper. If necessary, the layer formed from the decorative paper can be backed by so-called core papers.
- the object of the present invention was therefore to provide an additive which, when added to the impregnating resin solutions, enables the production of laminates, gives the wood-based materials coated therewith an improved abrasion resistance, without the use of the additives leading to process engineering problems Processing of the impregnation resin solutions and deterioration of the application properties of the wood material surfaces leads, in particular with regard to their water vapor resistance and color brilliance.
- coated solid particles described at the outset impregnating resin solutions containing them, paper films impregnated with these resin solutions and wood-based materials coated with these films, and processes for producing these articles were found.
- the core of the coated solid particles according to the invention consists of a solid such as quartz, nitride, carbide, SiO and corundum being preferred.
- the proportion of melamine resin with which the solid particles are coated is 35 to 55% by weight.
- the coated solid particles generally have a longest average diameter of 5 to 100, preferably 20 to 70 ⁇ m.
- the coated solid particles can be produced in a simple manner by first preparing a suspension from a melamine resin solution and the solid particles, for example by stirring the solid particles into the melamine resin solution.
- the suspensions preferably have a pH of 6 to 7.
- Suitable solid particles have a longest average diameter of 5 to 100, preferably 20 to 70 ⁇ m and are commercially available.
- melamine resin solutions are also commercially available and are known, for example, as impregnating or impregnating resins from Ulimann's Encyclopedia of Industrial Chemistry, Verlag Chemie GmbH, 4th edition, volume 7, pages 417 and 418. These are the condensation products of melamine, formaldehyde and, where appropriate, compounds such as urea and guanidines, which can react with formaldehyde in a condensation reaction. Melamine resin solutions which are particularly suitable for this purpose are described, for example, in DE-4111142 C2.
- the coated solid particles according to the invention can be prepared by spray drying melamine resin solution. Spray drying is preferably carried out at a temperature of 130 to 140 ° C.
- coated solid particles according to the invention are added to conventional impregnating resin solutions at any time before their processing and are suspended, for example, by stirring.
- the impregnating resin solutions to which the solid particles according to the invention are added are the same ones that are used to produce the coated solid particles.
- the proportion of solid particles according to the invention in these impregnating resin solutions according to the invention is expediently chosen so that the proportion of solid particles, calculated without a melamine resin layer, is 2 to 20, preferably 6 to 12,% by weight.
- the laminates and film of the invention improved in their abrasion resistance, can be produced in an analogous manner by this process, but the commercially available melamine Mining resin solutions are partially or completely replaced by the impregnating resin solutions according to the invention.
- the impregnating resin solutions according to the invention are generally mixed with a component which accelerates the curing.
- a component which accelerates the curing are, for example, the generally known hardeners or reaction products of aliphatic amines such as dimethylethanolamine with SO 2 or p-toluenesulfonic acid or methylethanolammonium sulfite.
- the hardener is generally added to these impregnating resin solutions in amounts of 0.1 to 1% by weight.
- the hardener is advantageously added to them immediately before the impregnation of the carrier materials.
- auxiliaries from the prior art can be added to these impregnating resin solutions, e.g. Antifoam and wetting agents, e.g. polyethoxylated alcohols.
- Decorative films improved in their abrasion resistance can be produced particularly inexpensively and simply by using
- step II the impregnated decorative paper obtained in step I is coated on one side with the impregnating resin solution according to the invention and the other side coated with the same solution or a customary impregnating resin solution.
- Highly abrasion-resistant overlay films according to the invention are generally produced by coating overlay papers on one side with the impregnation resin according to the invention.
- the impregnating resins according to the invention are applied to the decorative or overlay paper in such amounts that the proportion of solid resin, based on the paper weight, is 100 to 140% in the case of the decorative paper and 200-350% in the case of the overlay paper.
- the films and laminates according to the invention can be prepared by conventional methods for coating wood-based materials, e.g. Use chipboard, blockboard, plywood or medium-density fiberboard, if necessary, in combination with conventional films or laminates.
- One of these common methods is to press the films onto the wood materials at a temperature of 120 to 220 ° C.
- the pressure is generally 8 to 22 bar and the pressing time is about 8 to 55 seconds.
- the wood-based materials according to the invention produced in this way have a particularly good abrasion resistance and are therefore particularly suitable as floor coverings.
- a 70 g / m 2 paper with wood decor printing was impregnated with an impregnating liquor based on a commercially available melamine-formaldehyde resin (Kauramin ® resin 753 liquid from BASF AG) and at 120 ° C. to a residual moisture of 6. 5% dried.
- the solid resin content of the paper film was 100% based on the weight of the paper.
- a 28 g / m 2 overlay paper based on pure ⁇ -cellulose was processed with the in a second operation same impregnation liquor so treated that the proportion of solid resin was about 250%, based on the paper weight.
- the residual moisture content of the overlay film after drying was 7.0%
- Impregnation fleet for decorative film and overlay
- the powder obtained had a residual moisture content of 1-2, the bulk density was between 900 and 1100 g / 1.
- An 8 mm MDF board (medium density fiberboard) was coated with a decorative film according to Comparative Example 1 and then additionally with the following overlay films.
- the test was carried out with a Taber abraser in accordance with DIN 53 799 or EN 438-1.
- the measured value was the average of the number of revolutions that were required from the first attack of the printed image to the complete (95%) disappearance of the print decor.
- Resin liquors with a solid resin content of 55% and each containing 5 or 10% corundum were produced to determine the settling speed. A dependence on the time of sediment formation was measured.
