Description

Technical Field

[0001] The present invention relates to a resin-containing composition having antibacterial properties, particularly biocidal properties, for use as a surface coating on paper or board material, the application of said composition, paper or board coated with said composition, and a method for manufacturing paper or board material having an antiviral coating. Background Technology

[0002] Melamine-faced engineered wood panels and components are used in various fields, including furniture, flooring, and interior design. These panels and components are not only decorative but also possess excellent surface properties. Increasingly, there is also a growing demand for specific hygienic properties. It is known from melamine surfaces that they can be easily and quickly disinfected. The use of disinfectants generally does not cause surface changes. However, a common problem arises here: the surface coating only provides protection for a specific period because the active ingredient is not embedded in the surface. This active ingredient is subsequently applied and then removed from the surface again by cleaning or abrasion.

[0003] Ideally, the surface should require no disinfection at all, as it is inherently antibacterial or antiviral. This is particularly suitable for applications in the healthcare sector, such as doctors' offices, hospitals, nursing homes, and rehabilitation facilities. Therefore, effective and durable protection against bacteria or viruses should be embedded in the decorative surface to ensure lasting protection under the most favorable conditions. In particular, uncertainty arises regarding the remaining effectiveness of protection due to its slow degradation.

[0004] An example of this approach is described in WO 2013 / 156595 A1. Here, the surface active ingredient or surfactant contains nanomaterials, wherein an antibacterial nanomaterial complex is formed. A surfactant containing quaternary ammonium cations is used as the surfactant. Silicon nanoparticles or carbon nanotubes are mentioned as nanomaterials. The formed antibacterial complex is used to coat the surface.

[0005] Providing durable antimicrobial protection for engineered wood panels is difficult for non-professionals to achieve because they typically lack knowledge of the precise boundary conditions (coating amount, coating conditions, etc.) involved in manufacturing and application. Furthermore, the formulation used must be harmless to health and should therefore be applied only by trained personnel. Moreover, repeated application at regular intervals causes downtime. Such repeated application also, of course, incurs higher costs.

[0006] This results in various drawbacks, such as high costs, cumbersome solutions, persistent expenses, and uncertainty regarding protection features. Summary of the Invention

[0007] Therefore, the technical objective of this invention is to equip melamine resin surfaces with antiviral components. These components should be embedded in the resin matrix within the surface area. Naturally, the surface properties of the product should not be deteriorated by the addition of the active ingredient. Manufacturing antiviral surfaces should also be feasible using existing facilities. Under no circumstances should any toxic hazard originate from the modified surface, and such toxic hazard would in any way limit the possibility of use.

[0008] According to the present invention, this objective is achieved by the composition according to the present invention.

[0009] Accordingly, a resin-containing composition having antibacterial, biocidal, and especially antiviral properties is provided for a surface coating of paper layers or material boards, wherein the composition comprises:

[0010] - At least one formaldehyde resin, especially melamine-formaldehyde resin,

[0011] - at least one compound of general formula (I)

[0012] R 1 SiX3(I),

[0013] in

[0014] -X is an alkoxy group, and

[0015] -R 1 It is an organic residue selected from C1-C10 alkyl groups, which can be interrupted by -O- or -NH-, and

[0016] -where R 1 Having at least one functional group Q1, said functional group being selected from amino groups, methacrylate groups, methacrylate oxy groups, vinyl groups, and epoxy groups; and at least one other compound of general formula (II).

[0017] SiX4(II),

[0018] Where X is an alkoxy group, and

[0019] - At least one effective antibacterial substance, especially at least one biocidal agent.

[0020] It is feasible to introduce or embed biocidal active substances into resin mixtures or resin matrices, such as melamine resin matrices, using current compositions, which are coated onto the surface of a carrier material such as engineered wood or paper layers. For this purpose, current compositions having at least one silane compound of general formula (I) and optionally another silane compound of general formula (II) include a crosslinked hydrophilic component. The silane compound of formula (I) is bound to the resin component and the antibacterial active substance via functional group Q1. The silane compound of formula (II) is used to bind to the melamine resin and the antibacterial active substance via a SiO2 network constructed through the condensation of OH groups. The biocidal active substance is coupled to the silane. The complex consisting of the active substance and the silane can then be firmly bound to the melamine resin via a condensation process that occurs during curing or pressing.

[0021] It is important to note that current resin-containing compositions are not applied to inorganic, leather-containing, glass-containing, metallic, or semi-metallic coatings, surfaces, or materials. In particular, current resin-containing compositions are applied only to cellulose-containing surfaces and materials, such as paper and wood materials, but not to fabrics.

[0022] Nanoscale particles, such as those exceeding 200 μm, can be optionally added as described below. 2 The large surface area of ​​ / g enables further absorption of active substances and binding to the resin matrix via OH groups.

[0023] Besides silanes, other alkoxy compounds, especially alkoxy titanates such as isobutyl titanate, can also be used as adhesives between resins and active ingredients, but they hydrolyze and condense significantly faster than silanes.

[0024] The current composition can be used as a coating resin or an impregnation resin. In the case of impregnation resin, after core impregnation and intermediate drying of the paper layer (decorative paper, covering paper) with a commonly used impregnation resin, the current resin-containing composition can be applied to the upper side of the core-impregnated paper layer (impregnated material). However, the current resin-containing composition can also be applied to printed artificial boards.

[0025] Using the current composition offers several advantages. Therefore, long-lasting antimicrobial protection is achieved by embedding the active ingredient into the resin matrix; the active ingredient is difficult or impossible to wash off. Furthermore, disinfection costs are reduced because the active ingredient is introduced into the surface layer only once; repeated application of disinfectant can be avoided.

[0026] In an improved embodiment, instead of using silanes and biocides as separate components that form a silane-biocide complex after the reaction, a pre-prepared silane-biocide complex, such as 3-trimethoxysilylpropyldimethyloctylammonium chloride, is used.

[0027] The hydrolyzable residues X of general formulas (I) and (II) are advantageously selected from C 1-6 -alkoxy, especially methoxy, ethoxy, n-propoxy, i-propoxy and butoxy.

[0028] In a particularly preferred variant of the present composition, the compound of general formula (II) SiX4 includes methoxy, ethoxy, n-propoxy, or i-propoxy and butoxy as X. Particularly preferred are compounds of general formula (II) such as tetramethoxysilane and tetraethoxysilane.

[0029] Organic residues R of compounds of general formula (I) 1 Preferably selected from methyl, ethyl, n-propyl, isopropyl, n-butyl, s-butyl, t-butyl, pentyl, hexyl, heptyl, octyl, and cyclohexyl, which can be interrupted by -O- or -NH-.

[0030] In one embodiment of the present composition, at least one functional group Q of the compound of general formula (I) 1 Selected from epoxy groups, amino groups, and vinyl groups. A particularly preferred functional group is Q. 1 It contains glycidyl ether groups and aminoethylamino groups. Functional group Q 1 It can advantageously include residues having double bonds or epoxy groups, which can be activated and polymerized by means of UV radiation.

[0031] In one embodiment of the present composition, the functional group Q is present. 1 According to R 1 Compounds of general formula (I) of SiX3 can be selected from methacryloyloxypropyltrimethoxysilane (MPTS), aminoethyl-aminopropyltrimethoxysilane, epoxy-functionalized silanes such as glycidyl-oxypropyltriethoxysilane, or vinyl-functionalized silanes such as vinyltrimethoxysilane.

[0032] As described, residue R 1 Able to have at least one functional group Q 1 In addition, residue R 1 It can also exist by being replaced by other residues.

[0033] The term "substitution" when used with "alkyl," "cycloalkyl," "aryl," etc., refers to one or more atoms, typically the H atom, substituted by one or more of the following substituents, preferably one or two of the following: halogen, hydroxyl, protected hydroxyl, oxo, C3-C7 cycloalkyl, bicycloalkyl, phenyl, naphthyl, amino, protected amino, monosubstituted amino, protected monosubstituted amino, disubstituted amino, guanidinyl, protected guanidinyl, heterocycle, substituted heterocycle, imidazolyl, indolyl, pyrrolidinyl, C1-C 12 Alkoxy, C1-C 12 Acyl group, C1-C 12 Acyloxy, Acryloyloxy, Nitro, Carboxyl, Protected Carboxyl, Carbamoyl, Cyano, Methanesulfonylamino, Thiol, C1-C 10 Alkyl thio and C1-C 10 Alkyl sulfonyl group. The substituted alkyl group, aryl group, and alkenyl group can be substituted once or multiple times with the same or different substituents, preferably once or twice.

[0034] The term "aryl," as used herein, refers to an aromatic hydrocarbon, such as phenyl, benzyl, naphthyl, or anthracene. A substituted aryl group is an aryl group that is substituted with one or more substituents as defined above.

[0035] The term "cycloalkyl" includes the following groups: cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and cycloheptyl.

[0036] In one variant, it is possible to include at least one compound of general formula (I) and at least one compound of general formula (II), or at least two compounds of general formula (I) and at least one compound of general formula (II). Any combination is conceivable herein.

[0037] Therefore, one embodiment of the resin-containing composition can include:

[0038] - At least one formaldehyde resin, especially melamine-formaldehyde resin

[0039] -General formula (I)R 1 At least one compound of SiX3, wherein X is an alkoxy group and R is an alkoxy group. 1 It is an organic residue selected from C1-C10 alkyl groups, which can be interrupted by -O- or -NH-, and wherein R 1 Having at least one functional group Q 1 The functional group is selected from vinyl groups and epoxy groups, and at least one other compound of general formula (II)SiX4, wherein X is an alkoxy group.

[0040] The silane has proven to be particularly advantageous for incorporating and chemically bonding biocides with functional groups such as hydroxyl or carboxyl groups into resin matrices.

[0041] Another embodiment of the resin-containing composition may include:

[0042] - At least one formaldehyde resin, especially melamine-formaldehyde resin

[0043] -General formula (I)R 1 At least one first compound of SiX3, wherein X is an alkoxy group and R is an alkoxy group. 1 It is an organic residue selected from C1-C10 alkyl groups, which can be interrupted by -O- or -NH-, and wherein R 1 Having at least one functional group Q1, said functional group being selected from vinyl groups and epoxy groups, - general formula (I)R 1 At least one second compound of SiX3, wherein X is an alkoxy group and R is an alkoxy group. 1 It is an organic residue selected from C1-C10 alkyl groups, which can be interrupted by -O- or -NH-, and wherein R 1 It has at least one functional group Q1, said functional group being selected from amino groups, and at least one other compound of general formula (II)SiX4, wherein X is an alkoxy group.

[0044] The silane mixtures have proven particularly advantageous for incorporating and chemically binding into complexable biocides such as copper sulfate.

[0045] In a particularly preferred variant, the composition may have glycidyltriethoxysilane as compound (I) and tetraethoxysilane as compound (II). In another preferred variant, the composition may contain glycidyltriethoxysilane as the first compound of formula (I), aminoethylaminotriethoxysilane as the second compound of formula (I), and tetraethoxysilane as the compound of formula (II).

[0046] In the composition, the molar ratio of compounds of formula (I) and (II) can be in the range of 0.5:1 to 25:1, preferably between 5:1 and 15:1. Therefore, the molar ratio of glycyloxypropyltriethoxysilane to tetraethoxysilane can be in the range of 0.8:1 to 4:1, while the molar ratio of glycyloxypropyltriethoxysilane to aminoethylaminopropyltriethoxysilane can be in the range of 0.7:1 to 2:1.

[0047] As stated above, the effective antibacterial substance used is a biocide. Preferably, biocides containing silver or zinc are not used. A prerequisite for selecting a suitable biocide is that it corresponds to EU Regulation 528 / 2012 concerning the market placement of biocide products. Biocides can be classified according to product type, such as disinfectants and protectants, or according to their target organisms (viricides, bactericides, fungicides, etc.). Another fundamental prerequisite is the compatibility of the biocide with the resin used.

[0048] Currently, at least one biocide can be selected from: benzalkonium chloride, octylammonium chloride, chitosan, phenylphenol, copper sulfate, lactic acid, nonanoic acid, sodium benzoate, 1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2-yl]methyl]-1H-1, 2,4-triazole, 2-octyl-2H-isothiazolidin-3-one, thiazolidin-4-yl-1H-benzimidazole, 3-chloro-2-propynylcarbamate, biphenyl-2-ol, Brønsted / calcium magnesium oxide, copper(II) oxide, 2-pyridinium thiol-1-oxide, and 4-chloro-cresol. Particularly preferred biocides are benzalkonium chloride, chitosan, phenylphenol, copper sulfate, and 4-chloro-3-methylphenol. The listed active substances are derived from product series 2 and 9, which have been approved or are being approved for use in antiviral flooring.

[0049] At least one biocide can be included in the present composition (in the amount of a resin-free composition consisting of two silanes and a biocide) in an amount between 10% and 30% by weight, preferably between 15% and 25% by weight, more preferably between 18% and 23% by weight, for example, 20% or 22% by weight.

[0050] In a particularly preferred embodiment, the resin-containing composition comprises more than one biocide, particularly at least two biocides.

[0051] In other words, it has been found that in the case of certain biocides such as phenylphenol, when the amount of biocides is high, for example, more than 20% by weight, it can cause segregation of the resin-containing composition, thereby causing optical inhomogeneity on the surface.

[0052] To ensure high efficacy of the antiviral additive under these conditions, it has proven advantageous to add another biocide, such as 4-chloro-3-methylphenol, in a particularly deficient amount to the resin-containing composition. This avoids segregation while simultaneously ensuring good antiviral activity.

[0053] When using two biocides, (based on the amount of the resin-free composition consisting of the two silanes and the biocides respectively) the first biocide can be used in an amount between 15% and 25% by weight, preferably 20% by weight, while the second biocide can be used in an amount between 0.1% and 2% by weight, preferably between 0.3% and 0.8% by weight, particularly preferably 0.5% by weight.

[0054] In a particularly preferred variant, phenylphenol is used as the first biocide and 4-chloro-3-methylphenol is used as the second biocide. The amount of phenol can be 20% by weight, and the amount of 4-chloro-3-methylphenol can be 0.48% by weight.

[0055] However, it is also feasible to use the two biocides in a weight ratio between 1:0.5 and 1:1.5, especially 1:1; that is, the two biocides can be used, for example, in the same amount. The ratio is controlled by the specific characteristics of the biocides used.

[0056] The molar ratio of silane to the effective antiviral substance can be in the range of 100:1 to 5:1.

[0057] In another embodiment, the current composition can include inorganic particles, particularly SiO2-based nanoparticles, such as silica gel or zeolite. The particles used here preferably have a size between 2 nm and 400 nm, more preferably between 2 nm and 100 nm, and particularly preferably between 2 nm and 50 nm. By adding inorganic particles, the amount of absorbed active material can be further increased.

[0058] The mass ratio between oxides composed of alkoxy compounds and oxides composed of additional nanoparticles is 1.4:more than 1.26:1 to 1:2.3. Typical silica gels are silica sols, such as Levasil 200B30, CS 30716P, and CS20 516P. These silica sols have a deposition effect, which in turn improves effectiveness.

[0059] As already indicated above, in another embodiment, it is possible to add at least one alkoxytitanate, such as tetraisopropyl orthotitanate (isopropyl titanate) or tetraisobutyl orthotitanate (isobutyl titanate), to the present composition. These substances serve as an additional binder between the resin and the active ingredient; however, in the case of alkoxytitanates, unlike silanes, these substances hydrolyze and condense significantly more rapidly. Simultaneously, they increase the condensation rate of the entire system, making the removal of alcohol simpler and more feasible, thereby obtaining a purely aqueous system.

[0060] The ratio of silane to alkoxytitanate is 30:1, preferably 26.6:1.

[0061] Current resin-containing compositions are preferably used in an aqueous form, wherein they are alcohol-free or contain only a small amount of alcohol.

[0062] In the case of an aqueous composition, the aqueous composition can be prepared by a method comprising the following steps:

[0063] - Provide an aqueous suspension containing at least one compound of general formula (I) and at least one compound of general formula (II);

[0064] - Add at least one catalyst, especially an acid, to a suspension consisting of at least one compound of general formula (I) and at least one compound of general formula (II);

[0065] -Heating the mixture;

[0066] - Add at least one effective antibacterial substance, and optionally heat the mixture.

[0067] - Optionally, the formed alcohol phase (e.g., by evaporation) can be separated from the aqueous phase of a mixture consisting of at least one compound of formula (I), at least one compound of formula (II), and at least one antibacterial active substance;

[0068] - Add a mixture (or additive) consisting of two silanes and a biocidal agent to form a formaldehyde resin.

[0069] Suitable inorganic and / or organic acids for use as catalysts are selected from: phosphoric acid, acetic acid, p-toluenesulfonic acid, hydrochloric acid, formic acid, or sulfuric acid. Ammonium salts, such as ammonium sulfate, are also suitable, as they react as weak acids. p-Butanediol sulfonic acid is particularly preferred.

[0070] When inorganic nanoparticles, such as silica sol, are incorporated into the composition, the inorganic nanoparticles are preferably added together with the active ingredient. However, in a variation, the active ingredient can also be added at a time different from that of the silica sol, for example, after the silica sol.

[0071] The prepared aqueous suspension consisting of two silanes and a biocide is stable and can be stirred as an additive into aqueous, thermosetting formaldehyde resins such as melamine resin to create antibacterial surfaces. UV-curable polymers or paints are currently not used as a matrix for antiviral compositions or additives containing two silanes and a biocide.

[0072] However, it is also feasible to directly mix the individual components of the composition, namely the silane and the biocide, into the resin; that is, in this case, the composition does not exist as a separate additive, but rather is prepared in situ in the resin.

[0073] In this case, the composition is prepared in situ as follows:

[0074] - Provide resin suspensions, especially formaldehyde resin suspensions, such as melamine-formaldehyde resin;

[0075] - An aqueous suspension containing at least one compound of general formula (I) and optionally at least one compound of general formula (II);

[0076] - Add at least one catalyst, particularly an acid, to a suspension consisting of at least one compound of general formula (I) and optionally at least one compound of general formula (II).

[0077] -Heat the mixture.

[0078] - Add at least one antibacterial active ingredient and optionally add inorganic nanoparticles, such as silica sol;

[0079] Continue heating the mixture until a modified resin is obtained.

[0080] A resin suspension based on formaldehyde resin, having antibacterial properties, is provided by adding an antibacterial composition as an additive to a resin, or by in-situ preparation in a provided resin.

[0081] The amount of active substance or biocide added to the resin is set such that the resin suspension contains between 1% and 5% by weight, preferably between 2% and 3% by weight, based on the solid resin.

[0082] This antibacterial and effective resin suspension can be used to coat carrier materials, especially paper layers, such as decorative or covering paper layers, or especially engineered wood products, such as particleboard, medium-density fiberboard (MDF), high-density fiberboard (HDF), or OSB, plywood, or WPG.

[0083] Accordingly, a method for manufacturing a paper layer or engineered wood panel with antiviral properties is also provided, wherein at least one paper layer or engineered wood panel has at least one coating, particularly as a surface coating, wherein the at least one coating comprises at least one of the above-described resin-containing compositions. The resin suspension is typically applied to the engineered wood panel using rollers, while the resin suspension is applied to the paper layer using a rasterwerk.

[0084] Accordingly, a method is provided for achieving a surface coating on various carrier materials, such as engineered wood or paper layers, wherein the surface coating possesses antibacterial, biocidal, and especially antiviral properties. Therefore, the carrier material provided by this method has at least one antivirally effective coating, particularly at least one antivirally effective surface coating.

[0085] In one embodiment, a decorative paper layer or a covering paper layer is used as the paper layer.

[0086] In this case, the method achieves the preparation of an antivirally effective impregnated material. In one variant, the decorative paper layer or covering paper layer is first impregnated with at least one liquid or powdered resin composition. Subsequently, at least one coating comprising at least one formaldehyde resin, especially melamine-formaldehyde resin, and at least one composition thereof is applied to at least one outer side of the impregnated paper layer, said composition being prepared from at least one compound of general formula (I), at least one compound of general formula (II), and at least one antibacterial active substance, especially at least one biocide.

[0087] Therefore, the impregnated material prepared by this method has the following layer structure:

[0088] - At least one resin-impregnated paper layer, especially a decorative or covering paper layer; and - at least one antiviral effective coating disposed on at least one impregnated paper layer.

[0089] Currently, the term "impregnation" is understood as the complete or partial saturation of a paper layer with resin. This impregnation can be applied, for example, by rolling, anilox rolling, scraping, or by spraying in an impregnation bath.

[0090] As mentioned, for example, covering paper, decorative paper, or kraft paper can be used as the paper layer. Covering paper is typically thin paper that has already been impregnated with conventional melamine resin. Similarly, covering papers are available in which abrasion-resistant particles, such as corundum particles, are incorporated into the resin of the covering portion to improve abrasion resistance. Decorative paper is a special paper used for surface finishing of wood materials, achieving a high degree of decorative diversity. Therefore, in addition to typical prints on various wood structures, a wide range of prints on geometric shapes or artworks are available. In fact, there are no limitations on the choice of patterns. To ensure optimal printability, the paper used must have good smoothness and dimensional stability, and is also suitable for impregnation with the required synthetic resins. Kraft paper has high strength and is composed of cellulose fibers; starch, alum, and glue are added to it to achieve surface effects and enhance strength.

[0091] The paper layer is impregnated in two stages. First, the core is impregnated with a standard resin (melamine or urea resin, or a mixture of both) followed by intermediate drying. Then, melamine resin is coated onto the upper side of the impregnated material, containing the corresponding active ingredient in the resin, for example in an anilox machine. This is followed by another drying step. The pretreated impregnated material is then further processed into the desired intermediate or final product. This can be used for direct coating applications in furniture, interior design, or flooring. Laminates can also be manufactured, which can then be used for the aforementioned applications.

[0092] In one embodiment variation, the paper layer is treated as follows: First, the back side of the paper layer is impregnated (e.g., in an impregnation bath) with a resin having a solids content between 50% and 70% by weight, preferably 55% by weight. After passing through a breathing distance, the paper is further impregnated with the resin. The impregnated material is then passed through a drying channel, where it is dried back to a residual moisture content of 15%-20%. In a second impregnation step, a resin containing an antibacterial component and having a solids content between 50% and 70% by weight, preferably 55% by weight, is applied.

[0093] Another drying step is performed to bring the residual moisture content to approximately 6%. The impregnated material can then be pressed together with the engineered wood using conventional methods, such as in a short-cycle press.

[0094] Alternatively, the impregnated material with an antiviral coating can be pressed together with another paper layer. Therefore, in a preferred embodiment, a cover paper layer with an antiviral coating can be pressed together with at least one decorative paper layer (not impregnated with modified resin), at least one impregnated kraft paper layer, and at least one transparent paper layer (cellophane). This layer structure, from top to bottom, can be: a cover paper layer with an antiviral coating, a decorative paper layer (not impregnated with modified resin), optionally a cellophane layer, a kraft paper layer impregnated with modified resin, and a cellophane layer. The (flexible) laminate prepared in this way can then be pressed together with or bonded to a particleboard.

[0095] In another embodiment, particleboard, medium-density fiberboard (MDF), high-density fiberboard (HDF), or unspun fiberboard (OSB), plywood, or wood-plastic composite board (WPG) are preferably used as engineered wood products.

[0096] In this context, this method enables the manufacture of antiviral laminates.

[0097] In this variant, at least one decorative layer is first applied to at least one engineered wood panel, followed by the application of at least one antiviral effective coating comprising at least one formaldehyde resin, particularly melamine-formaldehyde resin, and at least one composition thereof, which may be prepared from at least one compound of general formula (I), at least one compound of general formula (II), and at least one antibacterial active substance, particularly at least one biocidal agent. This layered structure is then pressed to form a laminate.

[0098] Therefore, the laminate prepared by this method has the following layer structure:

[0099] -At least one type of engineered wood;

[0100] - At least one decorative layer disposed on the engineered wood panel, particularly in the form of a direct print or decorative paper layer; and

[0101] - At least one antiviral (resin-containing) coating is disposed on at least one decorative layer.

[0102] In one embodiment variation, the decorative layer is applied to the engineered wood panel, which serves as the carrier material, either in the form of a direct print or as a decorative paper layer. Subsequently, an antiviral-effective liquid resin layer can be applied to the decorative layer, the antiviral-effective liquid resin layer comprising at least one formaldehyde resin, particularly melamine-formaldehyde resin, and at least one composition, which can be prepared from at least one compound of general formula (I) and at least one antibacterial active substance, particularly at least one biocidal agent. Alternatively, a paper layer with an antiviral-effective coating can be applied as a covering layer. This could be, for example, the covering impregnation described above.

[0103] Accordingly, this method can be used to manufacture antiviral effective laminates for use as flooring, wall coverings, ceiling coverings, and furniture. The laminate has a carrier for a decorative layer or a decorative layer separately disposed on the carrier and a cover layer or a cover layer directly disposed on the decorative layer, which are pressed together under pressure and temperature to form a laminate. The above structure has at least an antiviral effective melamine-formaldehyde resin in the outer layer or outer sheet.

[0104] The pressing temperature here is related to the material of the carrier material. In the case of wood fiberboard such as MDF or HDF, or even in the case of particleboard, the pressing temperature is between 170°C and 230°C, preferably between 190°C and 200°C. However, in the case of WPG (wood-plastic composite) boards, the pressing temperature must be reduced by 30°C-40°C. Therefore, in the case of WPC (wood-plastic composite) boards, the pressing temperature is between 130°C and 180°C, for example, 150°C.

[0105] As already mentioned, in a preferred embodiment, the resin-containing antimicrobial composition can be coated onto a printed engineered wood panel.

[0106] For this purpose, a resin undercoat is first applied to the engineered wood panel or carrier board, and at least one base coat is then applied over the resin undercoat. The base coat preferably used here comprises a composition consisting of casein or soy protein as a binder and inorganic pigments, particularly inorganic colored pigments. White pigments such as titanium dioxide can be used as colored pigments in the base coat, or other colored pigments such as calcium carbonate, barium sulfate, or barium carbonate can also be used. In addition to the colored pigments and casein or soy protein, the base coat may also contain water as a solvent. It is also preferred that the coated colored base coat consists of at least one, preferably at least two, and particularly preferably at least four sequentially applied layers or coatings, wherein the amount of coating between the layers or coatings can be the same or different.

[0107] In another variant of the embodiment, a primer layer is applied to the substrate, preferably as a one-time coating and then dried. The primer layer is particularly important in the case of subsequent gravure printing methods (using rollers), while it is not absolutely necessary when applying digital printing methods.

[0108] The amount of liquid primer applied is 10g / m². 2 and 30g / m 2 Between 15g / m 2 and 20g / m 2 Between. It is preferred to use polyurethane-based compounds as primers.

[0109] Gravure printing and digital printing methods are advantageously applied as direct printing methods for printing engineered wood panels.

[0110] A cover layer, with or without additives, is applied to the decorative layer, and the amount and composition of the additives can vary.

[0111] Therefore, the following coating can be performed in a variant:

[0112] - Apply at least one first resin layer to at least one decorative layer on the upper side of the engineered wood panel, wherein the solid content of the first resin layer is between 60% by weight and 80% by weight, preferably 65% ​​by weight;

[0123] In one embodiment, the glass spheres used as spacing maintainers can be applied together with the third, fourth, and / or fifth resin layers. Preferably, the diameter of the glass spheres used is 80 μm-100 μm. The amount of glass spheres is 10 g / m². 2 Up to 50g / m 2 10g / m 2 Up to 30g / m 2 15g / m 2 Up to 25g / m 2The preferred formulation consists of approximately 40 kg of liquid resin, glass beads, and additives. The glass beads can also be in a silanized form. Silanization of the glass beads improves their embedding within the resin matrix.

[0124] As mentioned above, abrasion-resistant particles, such as those composed of corundum (alumina), boron carbide, silicon dioxide, and silicon carbide, can be spread onto the engineered wood panel. Corundum particles are particularly preferred. White corundum (white) with high transparency is preferred here, thereby minimizing any adverse effects on the optical effects of the decoration beneath it.

[0125] The amount of abrasion-resistant particles applied is 10 g / m². 2 Up to 50g / m 2 10g / m 2 Up to 30g / m 2 15g / m 2 Up to 25g / m 2 The amount of abrasion-resistant particles applied is related to the desired wear level and particle size. Therefore, when using a particle size of F200, at a wear resistance level of AC3, the amount of abrasion-resistant particles is approximately 10 g / m². 2 Up to 15g / m 2 Within the range, at a wear resistance rating of AC4, it is located at 15g / m. 2 Up to 20g / m 2 Between, and in the case of abrasion resistance rating AC5, it is located at 20g / m 2 Up to 35g / m 2 Between. Under the current circumstances, the manufactured plate preferably has an abrasion resistance rating of AC4.

[0126] Wear-resistant particles with particle sizes ranging from F180 to F240, preferably F200, are used. The particle size range for F180 is 53 μm to 90 μm, for F220 it is 45 μm to 75 μm, for F230 it is 34 μm to 82 μm, and for F240 it is 28 μm to 70 μm (FEPA standard). In a variation, white fused alumina (F230) is used as the wear-resistant particles.

[0127] The resin layer is dried at a dryer temperature between 150°C and 220°C, preferably between 180°C and 210°C, especially in a convection dryer. The temperature is adapted to the specific resin layer and can be varied in each convection dryer. However, other dryers can also be used instead of convection dryers.

[0128] In the pressing step immediately following the final drying step, under the influence of pressure and temperature, in a short-cycle press, at a temperature between 150°C and 250°C, preferably 160°C, and at 30 kg / m³... 2 and 60kg / m 2 The pressure layer structure is pressed under pressure. The pressing time is between 10 and 20 seconds, preferably between 12 and 14 seconds. Detailed Implementation

[0150] Example 7: Applying the composition according to the invention to decorative paper

[0151] On the impregnation channel, decorative paper (weight: 70g / m²) 2 Width: 2070mm) In the first impregnation step, aqueous melamine resin (solid content: 55% by weight) is used at 130g / m 2 The amount of material used for impregnation is [amount missing]. The production speed here is 50 m / min. Melamine resin contains commonly used additives (hardeners, wetting agents, defoamers, etc.).

[0152] The impregnated material then passes through a drying channel, where it is dried back to a residual moisture content of 15% to 20%.

[0153] Then, in the second impregnation step, 40g of melamine resin (fl / m) is coated using an anilox roller. 2 The resin contains 2% by weight of an antiviral active substance in its solid resin. The solid content of the melamine resin is approximately 55% by weight.

[0154] The impregnated material is then dried again in a flash dryer. It is dried to a residual moisture content of 5.5% to 6.0% by weight. The impregnated material is then cut to size (2.8 or 5.6 × 2.07 m) or rolled up. Subsequently, the size is pressed onto particleboard in a short-cycle press, while zero samples without effective substances in the surface are tested simultaneously. The pressing parameters are: pressing pressure 40 kg / cm². 2 Pressing temperature: 190℃, pressing time: 15 seconds.

[0155] Perform the common tests defined in the warranty coverage on the coated board.

[0156]

[0157] *Except for the acidity test, the tests were conducted in accordance with DIN EN 14323-2017-07.

[0158] **Phase 1: No findings**

[0159] Stage 2: Slight changes in gloss and / or color

[0160] Stage 3: Sharp changes in gloss and / or color

[0161] As can be seen from the table, no anomalies were found.

[0162] Samples produced are sent to a testing laboratory so that the antiviral activity of surface tissues and materials can be tested using non-enveloped test viruses.

[0163] Here, in all tested samples, when tested according to ISO 21702:2019-05 "Measurement of antiviral activity on plastic surfaces and other non-porous surfaces", the antiviral effect A (log10 PFU) value was greater than 3 (ISO 18184:2014-09 Annex G). Therefore, a significant reduction was achieved in all tested samples.

[0164] Example 8: Applying the composition according to the invention to the covering portion

[0165] In the impregnation channel, the covering part (weight: 25g / m²) 2 Width: 2070mm) In the first impregnation step, aqueous melamine resin (solid content: 55% by weight) is used at 135g / m 2 The amount of material used for impregnation is [amount missing]. The production speed here is 50 m / min. Melamine resin contains commonly used additives (hardeners, wetting agents, defoamers, etc.).

[0166] The impregnation solution then passes through a drying channel, where the impregnated material is dried back to a residual moisture content of 15%-20%.

[0167] Then, in the second impregnation step, 40g of melamine resin (fl / m) is coated using an anilox roller. 2 The resin contains 2% by weight of an antiviral active substance in its solid resin. The solid content of the melamine resin is approximately 55% by weight.

[0168] The impregnated material is then dried again in a flash dryer. It is dried to a residual moisture content of 5.5% to 6.0% by weight. The impregnated material is then cut to size (2.8 or 5.6 × 2.07 m) or rolled up. Subsequently, the size is pressed into a laminate in a continuous press. The following structure is used here:

[0169] - A covering impregnated material containing effective antiviral substances (see above).

[0170] - Decorative impregnation material (paper weight: 70g / m²) 2 Resin coating: 100% by weight melamine resin, VC value: 5.6%-6.0%)

[0171] - Core layer (bottom impregnation material NKP; paper weight: 160g / m²) 2 Resin coating: Approximately 85% by weight of mixed resin (sold separately).

[0172] - Parchment (paper weight: 50g / m³) 2 ).

[0173] The pressing parameters are: feed rate: 8 m / min, pressing pressure: 80 kg / cm². 2Pressing temperature: 190℃.

[0174] The laminate is then glued to a 38mm particleboard (adhesive: urea-formaldehyde resin), the particleboard having a working board outline on one side, and then the laminate protrusions are formed and pressed around the glued outline on a post-forming line.

[0175] Laminates can also be used in vertical applications. Here, a decorative impregnating material with antiviral properties can be used instead of the covering.

[0176] Example 9: Applying the composition according to the invention to a cover layer

[0177] On the impregnation channel, the coating layer (weight: 25g / m²) 2 Width: 2070mm) In the first impregnation step, aqueous melamine resin (solid content: 55% by weight) is used at 135g / m 2 The amount of material used for impregnation is 50 m / min. The production speed is 50 m / min. Commonly used additives (hardeners, wetting agents, defoamers, etc.) are contained in the melamine resin. After resin coating, corundum is spread onto the upper side of the covering using a spreading device. This involves F230 (FEPA standard). The coating amount is 20 g / m. 2 .

[0178] The impregnated material then passes through a drying channel, where it is dried back to a residual moisture content of 15%-20%.

[0179] Then, in the second impregnation step, 40g of melamine resin (fl / m) is applied using an anilox roller. 2 It is applied to the back side of the covering. The resin contains 2% by weight of antiviral active substance in the solid resin. The solid content of the melamine resin is approximately 55% by weight.

[0180] The impregnated material is then dried again in a flash dryer. It is dried to a residual moisture content of 5.5% to 6.0% by weight. The impregnated material is then cut to size (2.8 or 5.6 × 2.07 m) or rolled up. Subsequently, the size is pressed into flooring structures for laminate flooring in a short-cycle press. The following structures are used here:

[0181] - A covering impregnated material containing effective antiviral substances (see above).

[0182] - Decorative impregnation material (resin coating: 100% by weight melamine resin, VC value: 5.6-6.0%) HDF, 8mm,

[0183] -Reverse tensile impregnation material (paper weight: 80g / m²) 2 Resin coating: 120% by weight)

[0184] - The pressing parameters are: pressing pressure 40 kg / cm² 2 Pressing temperature: 190℃, pressing time: 12 seconds.

[0185] The overlay can also be used to manufacture floor structures where HDF is directly printed. Then, in this location, the overlay is used instead of the final resin coating containing the effective antiviral substance.

[0186] Example 10: Applying the composition according to the invention to a wood-based panel

[0187] HDF (size: 2800×2070×7mm) is first primed with melamine resin on a direct printing production line (coating amount: approximately 20g melamine resin fl / m). 2 Solids content: approximately 65% ​​by weight). The resin is dried in a circulating air dryer and then coated with a colored primer, which consists of titanium dioxide and casein. This colored primer is applied up to seven times. The coating amount is 5-10 g of primer fl. / coating work. After each coating, intermediate drying is performed using circulating air and / or an IR dryer. Then, a primer is applied (coating amount 10-20 g fl. / m). 2 The primer will also be dried. Then, the decoration will be printed onto the primer using gravure or digital printing methods.

[0188] Subsequently, a coating layer composed of melamine resin is applied (coating amount: 10-30g melamine resin fl / m). 2 Solid content: 65% by weight). Melamine resin contains glass beads (diameter of glass beads: 80μm-100μm, coating amount: 5g glass beads / m). 2 As a spacing maintainer, the plate passes through the dryer again. Then, the plate is cooled in a chain bucket elevator (Paternoster).

[0189] Then, on the production line, the top side of the board is coated with melamine resin (coating amount: 60g melamine resin fl / m). 2 (Solid content: 65% by weight). Simultaneously, melamine resin is applied to the back side in the same amount using a roller as a counter-tensioning layer. Then, corundum is sprinkled onto the upper side of the plate (coating amount: 20g corundum / m²). 2 Particle size: F230 according to FEPA standard. The structure is air-dried or dried in a dryer by means of an IR radiator or circulating air. Subsequently, 30g of melamine resin fl. / m is applied using a roller coating unit. 2 (Solids content: 60% by weight) Apply two more coats. Each coat is followed by an intermediate drying period.

[0190] In the final roller coating process, 40g of melamine resin (fl. / m) was coated using an anilox roller. 2 The resin contains 2% by weight of an antiviral active substance in its solid resin. The solid content of the melamine resin is approximately 55% by weight.

[0191] The plates are dried in a circulating air dryer. Then, the plates are transferred to a short-cycle press. There, the structure is then subjected to drying at T = 180°C and p = 30 kg / cm². 2 Pressing is performed at t=14 seconds. A press plate with a handmade paper structure is used.

[0192] Design Example 11: Additive AV-30

[0193] This relates to an aqueous additive that does not contain residual alcohol, which can be incorporated into the resin during production. In different facilities, alcohol at certain concentrations can cause explosion-related issues. Furthermore, emission regulations impose requirements during mass processing. Therefore, efforts are being made to modify AV-3-based additives to produce purely aqueous, non-flammable additives.

[0194] Preparation instructions for additive AV-31:

[0195] 20.0 g glycidyltriethoxysilane and 12.8 g tetraethoxysilane were provided in a stirred flask. A mixture consisting of 18.1 g H₂O and 0.44 g ion exchanger (Lewatit 2629) was added. The mixture was heated to approximately 60 °C and stirred for approximately 120 minutes. The ion exchanger was then sieved off, and the mixture was heated to 80 °C under reflux. After 60 minutes, 10.7 g phenylphenol (approximately 22.4 wt%) was added, and the hydrolysate was then held at 80 °C for another 60 minutes after adding a mixture consisting of 3.3 g deionized water, 2.1 g dipropylene glycol monomethyl ether, and 0.3 g sodium dodecylbenzenesulfonate. The alcohol produced during hydrolysis was removed (approximately 19 g) by means of a rotary evaporator after a 12-hour standing time. The flash point of the additive was now >85 °C. The additive could now be added to an aqueous melamine resin.

[0196] Production trials have shown that insufficient mixing (e.g., facility shutdown or insufficient rotation speed during mixing) can cause segregation, which in turn leads to optical inhomogeneity, severely interfering with the optical appearance of furniture surfaces.

[0197] Laboratory tests showed that this was particularly due to the phenol content. Without separation, the maximum phenol content was <20% by weight.

[0198] In order not to reduce the effectiveness of the additives or jeopardize production safety, the content of phenylphenol was slightly reduced and replaced with another approved biocidal product (4-chloro-3-methylphenol).

[0199] Example 12: Additive AV-34+:

[0200] Preparation instructions for additive AV-34+.

[0201] 20.0 g glycidyltriethoxysilane and 12.8 g tetraethoxysilane were provided in a stirred flask. A mixture consisting of 18.1 g H₂O and 0.44 g ion exchanger (Lewatit 2629) was added. The mixture was heated to approximately 60 °C and stirred for approximately 120 minutes. The ion exchanger was then sieved off, and the mixture was heated to 80 °C under reflux. After 60 minutes, 9.56 g phenylphenol (approximately 20 wt%) and 0.23 g 4-chloro-3-methylphenol (approximately 0.48 wt%) were added, and the hydrolysate was then held at 80 °C for another 60 minutes after adding a mixture consisting of 3.3 g deionized water, 2.1 g dipropylene glycol monomethyl ether, and 0.3 g sodium dodecylbenzenesulfonate. The alcohol produced during hydrolysis was removed (approximately 19 g) by means of a rotary evaporator after a 12-hour standing time. The flash point of the additives was now >85 °C. The additive can now be added to water-containing melamine resin.

[0202] Laboratory tests have shown that this small addition of 4-chloro-3-methylphenol does not produce odor interference due to the new biocide. An odor is only perceptible at processing temperatures above 150°C when the concentration exceeds 0.8% by weight.

[0203] Aside from odor interference, it was able to increase the content of 4-chloro-3-methylphenol to 28% by weight without any unevenness being observed.

[0204] Practical tests have shown that even with prolonged placement, no surface inhomogeneity is now caused, and no segregation is observed.

[0205] Antiviral test:

[0206] According to ISO 217022:2019-05 "Measurement of antiviral activity on plastic surfaces and other non-porous surfaces", the antiviral activity of the antiviral composition was examined.

[0207] The results showed that for AV-1 to AV-6, significant antiviral activity with log10 PFU higher than 4.5 was generated with respect to phage MS2 (DSM 13767).

[0208] A 97.2% reduction in virus was also observed for bovine coronavirus (BoCV).
