Definitions
- the invention relates to a two-component polyurethane system for smoothing edges of chipboard, fiber and plywood panels.
- DE 35 11 754 describes a reactive mass based on polyurethane and its use for the production of coatings in the furniture sector.
- This invention has for its object to close the cut edges of chipboard, fiber and plywood panels, which are manufactured in different shapes and thicknesses and cut to certain dimensions, for the following reasons: a) To adapt the finish to the design of the Surface, b) to seal against moisture, c) to protect against breaking out of plate parts and d) to prevent damage and injuries to other bodies that hit the edge of the plate.
- the task arises to provide a simpler and less expensive method for shaping and smoothing edges of chipboard, fiber and plywood panels.
- the solution according to the invention can be found in the patent claims. It consists essentially in that the two-component polyurethane system is pasty and has such a high viscosity that the viscosity at 20 ° C is 150 to 350 Pas, measured with the Brookfield RVT viscometer, or that it is thin and the viscosity within increases from 5 to 15 seconds at 20 ° C. to such a high value that a 5 mm thick PUR layer runs less than 0.5 mm from a vertical chipboard, fiber or plywood board, preferably does not run at all.
- the two-component polyurethane systems according to the invention are therefore pasty or show thixotropic behavior immediately after application. This makes it easy to coat edges to remove unevenness and voids, without any shapes.
- the application can be done with a transfer belt or with a nozzle.
- a squeegee for shaping and smoothing is expediently connected immediately after the application.
- the final shaping can also be done by grinding, milling or sanding.
- the Shore hardness D of the two-component polyurethane system should expediently be> 65 for grinding.
- the viscosity increase or thixotropy both prevents the smoothing agent from running off and enables the smoothing agent to penetrate into the pores and unevenness of the edge.
- the smoothing agent to be used according to the invention therefore does not remain as a layer on the edge, but penetrates into the depressions. Therefore, no holes are created during the subsequent grinding or milling of the hardened smoothing agent, even if you grind or mill to the original dimension.
- the two-component polyurethane system to be used according to the invention preferably has a viscosity of 200 to 250 Pas at 20 ° C., measured with the Brookfield RTV viscometer. This pasty behavior can be obtained in a known manner, for example by adding a suitable amount of inorganic fillers, with or without an organic coating. Fumed silica is preferably used to achieve the desired viscosity.
- Suitable inorganic fillers are carbonates, in particular calcite, limestone, chalk and magnesium / calcium carbonate double salts such as dolomite, sulfates such as barium and calcium sulfate, oxides and hydroxides such as aluminum oxide, aluminum oxide hydrates and silicon dioxide as quartz powder or diatomaceous earth, silicates such as kaolin, feldspar , Wallostonite, mica, clay and talc, graphite or glass fibers.
- Calcium carbonate with a stearic acid coating can be used as an inorganic filler with an organic coating.
- hydrophobic ones are also customary, in which OH groups are replaced by alkyl groups.
- the thixotropy is preferably built up within 6 to 12 seconds.
- the two-component polyurethane systems to be used according to the invention are available if the polyol component contains a mixture of polyamide amines with a low-molecular polyfunctional amine, which is a compound with an average of about 2 amino groups per molecule or a representative of the homologous series of alkanoamines which is liquid at room temperature acts.
- Particularly suitable polyamide amines to be added to the polyol components include those which can be obtained by reacting oligomerized fatty acids such as tricarboxylic acids with an excess of polyvalent amines.
- a plasticized polyamide amine resin based on oligomerized unsaturated fatty acids, whose average molecular weight is approximately 1,200 and which corresponds to the average composition C72H150N9O 3 has proven to be very particularly suitable; the viscosity at 25 ° C is about 3000 Pas.
- These resins are obtained by condensation or amidation of (a) oligocarboxylic acids from the oligomerization of unsaturated fatty acids with preferably at least 50% by weight trimer content, preferably a composition of 0 to 2% monomeric fatty acids, 10 to 50% dimeric fatty acids and 50 to 90% trimeric fatty acids, with (b) excess of a heterocyclic amine of the general formula
- R is an alkylamino group or H, -R'NH 2 , where R 'is a saturated aliphatic hydrocarbon chain, preferably one
- Suitable polyfunctional amines are those which have an average of about 2 amino groups per molecule. These include cycloaliphatic diamines and diamines based on a polyether, such as Polyoxypropylene-alpha-omega-diamine as well as liquid aromatic diamines.
- Suitable aromatic diamines include 2,4-diaminomesitylene, 1,3,5-triethyl-2,4-diaminobenzene, 1,3,5-triisopropyl-2,4-diaminobenzene, 4,6-dimethyl-2-ethyl-1 , 3-diaminobenzene, 3,5,3 ', 5'-tetraethyl-4,4'-diaminodiphenylmethane,
- the above-mentioned amino compounds can also be used as liquid preparations together with other components.
- Such components can be, for example, esters and / or oligomerized or polymerized esters. If necessary, these can also be NCO-reactive Contain hydroxyl groups.
- esters include carbonates and polycarbonates, in particular propylene-1,2-carbonate.
- suitable amine preparations usually consist of one third to one half of such esters.
- Such preparations are also commercially available, for example Baytec 110 from Bayer.
- Suitable polyols include the polyols known per se for two-component polyurethane systems, as are described, for example, in DE 38 27 378 and EP 354 471, preferred polyol components being used in the examples below.
- polyesters Preferred here are polyesters, polyacetals, polyethers, polythioethers, polyamides and / or polyesteramides, each of which has on average 2 to 4 hydroxyl groups.
- polyethers e.g. the polymerization products of ethylene oxide, propylene oxide, butylene oxide and their mixed or graft polymerization products, and those obtained by the condensation of polyhydric alcohols or mixtures thereof and the polyethers obtained by alkoxylation of polyhydric alcohols, amines, polyamines and amino alcohols.
- Isotactic polypropylene glycol can also be used.
- polyacetals e.g. the compounds which can be prepared from glycols such as diethylene glycol, triethylene glycol, hexanediol and formaldehyde are questionable. Suitable polyacetals can also be prepared by polymerizing cyclic acetals.
- polythioethers are, in particular, the condensation products of thiodiglycol with itself and / or with other glycols, dicarboxylic acids, Formaldehyde, amino carboxylic acids or amino alcohols listed.
- the products are polythioethers, polythio mixed ethers, polythioether esters, polythioether ester amides.
- Such polyhydroxy compounds can also be used in alkylated form or in a mixture with alkylating agents.
- the polyesters, polyester amides and polyamides include those obtained from polyvalent saturated and unsaturated carboxylic acids or their anhydrides and polyvalent saturated and unsaturated alcohols, amino alcohols, diamines, polyamines and their mixtures, predominantly linear condensates, and e.g. Polyterphthalate or polycarbonate. Lactone polyester, e.g. Caprolactone or from hydroxycarboxylic acids can be used.
- the polyesters can have hydroxyl or carboxyl end groups. Higher molecular weight polymers or condensates, such as e.g. Polyethers, polyacetals, polyoxymethylenes (with) can be used.
- Polyhydroxyl compounds already containing urethane or urea groups and, if appropriate, modified natural polyols such as castor oil can also be used.
- polyhydroxyl compounds which have basic nitrogen atoms are also suitable, e.g. polyalkoxylated primary amines or polyesters or polythioethers which contain alkyl diethanolamine in condensed form.
- Solids can also be incorporated into the polyol component, which do not act as physical thixotropic agents, but perform other functions, e.g. Desiccants, pigments, extenders, fillers, dispersion aids.
- Suitable isocyanate components are those which are also known per se for use in two-component polyurethane systems and can be described for example in DE 38 27 378.
- MDI industrially manufactured 4,4'-diphenylmethane diisocyanate
- TXDI tetramethylxylene diisocyanate
- IDPI isophorone diisocyanate
- the ratio of low molecular weight multifunctional amines to polyamide amine is from about 10: 1 to 2: 3 parts by weight. Although this ratio does not appear to be extremely critical, the weight ratios of methyl diethyldiaminobenzenes from about 2: 1 to 4: 1 are preferred.
- the proportion of the combination of amines in the polyol component is 1 to 10% by weight, preferably 2 to 6% by weight, in particular 3 to 5% by weight.
- the polyfunctional amines and the polyamide amine of the polyol components are preferably added before the reaction with the isocyanate component. Usually, the polyol component and the additives are intimately mixed with the isocyanate component immediately before application.
- a suitable polyol component contains, for example: 15 to 100% by weight of polyol
- desiccant such as zeolite
- auxiliaries such as Dyes or catalysts
- the suitable ratio of polyol component to isocyanate component can best be indicated by the stoichiometric ratio of NCO-reactive to NCO groups. This ratio is in the range from 3: 2 to 2: 3, in particular in the range from 1: 1 to 3: 4. An excess of NCO groups of about 10 to 30% is optimal.
- the use of these pasty or thixotropic two-component polyurethane systems has several advantages compared to the liquid DE 35 11 754:
- the smoothing agent is so stable that it does not run off even with vertical processing, e.g. on the top or bottom of the plate. Even after grinding to the original dimension, a hole-free and pore-free surface is obtained by at least partially introducing the smoothing agent.
- Liquid smoothing agents on the other hand, often require two coating passes due to the penetration effect in the plate material.
- both products were applied to chipboard with a 20 mm edge width using a 20 mm wide slot nozzle.
- the thickness of the polyurethane layer was 1 mm.
- the edges were coated in one step, ie immediately after application to one edge, the plate was rotated by 90 ° C and then the next edge coated. The 1 mm thick order is retained. The coating mass does not run off the chipboard.
- the PU was cured by passing the coated panels through a heating duct at 130 ° C.
- the high temperature resistance of the polyurethane layer prevents film retraction even when stored at 120 ° C.
