Definitions
- the invention relates to a process for the preparation a lightweight fiberboard according to the preamble of the claim 1 and on a lightweight fiberboard according to the preamble of patent claim 15.
- the invention relates a lot to fiberboard low density, in particular as insulating material, but also as Design elements can be used, and on their Production.
- a typical representative of known fiberboard the aforementioned field of application are so-called wood soft fiber boards.
- a so-called dry process for the production of fiberboards from lignocellulosic fibers and binders is known.
- the fibers are obtained in the same way as for the wet process. Subsequently, however, they are not transferred into a suspension, but dried in current dryers, ie in flight, to a level that later allows easier removal of the residual moisture.
- the residual moisture content of the fibers after drying is less than 20%, typically less than 10%.
- a binder is added to the fibers, which, after the subsequent shaping of the fibers into a fiber mat during hot pressing of the fiber mat between pressure-controlled heating surfaces to a fiberboard, glues the individual fibers together.
- Dry-laid fibreboards are subdivided into high-density fibreboard (HDF), medium-density fibreboard (MDF), light and ultra-light fibreboard (ULF) within a density range of 900 to 450 kg per m 3 .
- Characteristic of fiberboard according to the known dry process is that even with so-called ultra-light fibreboard (ULF) due to the still relatively high density no good insulation effects are achieved and when using the fiberboard as construction elements, the relatively high weight of the fiberboard is taken into account.
- ULF ultra-light fibreboard
- these known fiberboard on smooth closed surfaces that are directly coated even with thin materials.
- the activation of the binder should be done for example by steam. To harden the fiber mat, this is to be flowed through with a drying medium, for example with hot air. If a thickness formation takes place in a press, the pressing surfaces should be designed like a sieve. In this way, as in a wet process fiberboard with open and structured by the screen surfaces used surface are produced, which thus also have all the disadvantages of known produced in the wet process fiberboard.
- a process for the production of polyurethane-bonded fiberboard is known, which is classified as a special dry process.
- the known method makes use of a binder having a first, NCO-containing binder component and a second, at least one polyol-containing binder component.
- the at least two binder components are applied separately or at least without significant pre-reaction in the mixture on fibers, so that the polyurethane bond takes place as late as possible in the manufacturing process and thus substantially during a hot pressing as a heat treatment.
- the second binder component comprising the polyol is applied to the fibers, while the first NCO-containing binder component is applied to the same fibers only thereafter and as late as possible before the fibers are formed into the fiber mat.
- the binder components for the polyurethane bond or suppressing a pre-reaction of the binder components the entire reactivity of the binder for the bonding of the fibers during hot pressing of the fiber mat to the fiberboard should be maintained. Namely, it is known that the polyurethane reaction between the binder component containing the NCO groups and the binder component containing the polyol spontaneously starts when these two binder components come together unless it is chemically blocked.
- the invention has for its object to provide a method for Production of light fiberboard according to the preamble of Claim 1 show that simple and economical is feasible and yet improved to fiberboard with Surface properties leads. Furthermore, a slight Fiberboard according to the preamble of claim 15 be shown, the improved surface properties having.
- Advantageous embodiments of the method are in the Subclaims 2 to 15 and advantageous embodiments of Fiber board described in the subclaims 16 to 20.
- the new process is a dry process because the fiber moisture content of the fibers is less than 20% when calibrating the fiber mat and during the heat treatment to cure the binder. It can be in the range below 10% as with conventional dry processes.
- the heat treatment of the fiber mat via smooth closed heating surfaces, via which the heat is transferred to the curing of the binder on the fiber mat. It is important that the heating surfaces are distance-controlled and not pressure-controlled, as is the case when carrying out conventional drying processes.
- the very low bulk density of the fiber boards produced by the new process does not allow controlled pressure control of the heating surfaces.
- the fiber mat before heat treatment with To spray water or an aqueous solution.
- To spray water or an aqueous solution In this way can be steamed by water evaporating on the heating surfaces be directed into the interior of the fiber mat, there the Curing of the binder promotes.
- the water gives way to the Fibers on the surface of the fiber mat, so that through the Influence of smooth heating surfaces particularly good smooth surfaces can be achieved in the finished fiberboard.
- the fiber mat through the spaced controlled heating surfaces also be calibrated.
- the thickness of the is typically 20 up to 300 mm. It's just in the area of bigger thicknesses in This area amazing that the fiberboard still after can be produced by a dry process.
- the Density profile of the fiberboard is adjusted so that an edge exaggeration of the density compared to the middle Density of the fiberboard of at least 60% results.
- a Stronger marginal increase in density is the basis for the Forming a particularly strong closed surface of finished fiberboard, for example, a considerable Pressure stability compared to the average density of the Can have fiberboard.
- a common synthetic resin of the wood-based material industry can be used as the binder.
- the usual synthetic resins of the wood-based materials industry include urea-formaldehyde, melamine-urea-formaldehyde, melamine-urea-phenol-formaldehyde, phenol-urea-formaldehyde, phenol-formaldehyde and PMDI resins.
- a foaming polyurethane binder may be used as the binder.
- the advantage of filling the voids in the fiberboard between the individual fibers by the polyurethane foam is no longer noticeable in an economically utilizable way.
- the particularly light fiberboard in the range below 150 kg / m 3 but can not be produced in usable quality without the use of a foam-forming binder.
- foam-forming polyurethane binder may be a so-called One-component system are used, which for example was developed by the company Bayer and basically is available.
- foam-forming Polyurethane binders a first, having NCO groups Binder component and a second at least one polyol comprising binder component.
- the fibers before applying the Binder divided into at least two batches and on a first of these games only the first having the NCO groups Binder component and on a second of these parts only the second, the polyol-containing binder component to apply and the parts of the fibers only just before molding to mix the fiber mat together.
- the two binder components so completely separated from each other. Also during mixing The parts of the fibers are not yet worth mentioning Contact of the two binder components. Only when molding the Fiber mat turns this contact at the contact points of the Fibers. But this contact is still not enough to alone trigger a significant amount of polyurethane reaction.
- the first batch can basically be 10 up to 90% and the second batch corresponding to 90 to 10% of the contain entire fibers. But it makes sense if the first and second parts of the fibers are about the same size are, d. H. For example, each 40 to 60% of the total Contain fibers.
- the new process can be both discontinuous as well be carried out continuously, which is preferred.
- at continuous process control are the heating surfaces typically at rear heated metal endless belts intended.
- the batches of fibers can Binder components and before mixing them separately be stored by each other.
- the reactivity of the Binder components increases in separate storage of the Part of the fibers does not decrease even for longer periods of time.
- the heat treatment can be made be that in the middle of the molding a temperature of only 50 to 100 ° C is reached. That means that compared to known methods very low temperatures in the middle of the Shaped body are sufficient. These result inversely in a high efficiency of the used in the heat treatment Energy and short periods of time for the heat treatment needed.
- the low temperature is at the new Process at least then for the curing of the binder content in the middle of the molding sufficient if highly reactive polyurethane binders are used, whose Reaction is not chemically hindered to a pre-reaction suppress.
- the fibers used in the new process be processed, wood fibers in the form of conventional Defibratormaschinestoff.
- the binder content can be far in the new process Borders are selected by the necessary strength of the Fiberboard on the one hand and the economy of the Process face high binder costs on the other hand are set.
- the following information refers to the Use of a polyurethane binder.
- the average density of the shaped body is adjusted to 60 to 250 kg per m 3 , wherein the binder content of the molding is adjusted to a total of 2.5 to 5% by weight based on atro wood fibers.
- the average density of the molding is adjusted to 250 to 400 kg / m 3 , wherein the binder content of the molding is adjusted to a total of 7 to 15% by weight based on atro wood fibers.
- the new method can also be carried out so that the Forming the preform from the fibers using a layer construction different compositions and / or proportions of Binder is set in each layer. So for example, the binder levels in the topcoats a fiberboard be larger than in the middle layer, to a particularly high stability of the outer layers too to reach. But there are also other layer structures for Adaptation to specific requirement profiles with the new procedure realizable. It is understood that lots of Fibers used for different layers of the layer structure are provided, not with each other before forming the fiber mat but only those fibers that are mixed for each provided a layer of uniform composition are.
- mechanically stable fiberboards result using a foam-forming binder, ie a polyurethane binder which has at least two binder components PMDI and polyol or which is a one-component system.
- a foam-forming binder ie a polyurethane binder which has at least two binder components PMDI and polyol or which is a one-component system.
- Such fiber boards may also be considered fiber stabilized polyurethane foam.
- the binder content of atro fibers is at least 5%, so in absolute terms it is still relatively small.
- binder content can be reduced when using a foam-forming polyurethane binder below 5% atro fibers. If the stabilities are not paramount, binder levels down to within 1% may be sufficient. All percentages are, as usual, weight percentages.
- binder content should also be selected for lower strengths above 5%, and for higher strengths 7 to 15% binder content should be used.
- a foam-forming binder can be used, in which case high-strength fiberboard can be produced even with relatively low binder levels.
- the method illustrated in the flow chart of the figure for the production of polyurethane-bound molded body goes from wood 1, which is comminuted in the usual way and then in a defibrator 2 in individual wood fibers 3 is digested. The stream of wood fibers 3 is then in a Dividing device 4 divided into two parts 5 and 6, wherein the games 5 and 6 are the same size. On the wood fibers 3 of the Lot 5 becomes in an applicator 7 an NCO groups containing binder component 8, a so-called PMDI, applied.
- the formulation of PMDI 8 corresponds to one such as those commonly used in the wood-based panel industry sole binder is used.
- one at least one Polyol-containing binder component 10 applied on the wood fibers 3 of the Lot 6 is in an applicator 9 one at least one Polyol-containing binder component 10 applied.
- it is preferably a mixture of short chain with a long-chain polyol.
- a mixture one part of diethylene glycol and one part of polyether alcohol the molecular weight 1000 can be used.
- Both application devices 7 and 9 work on the principle that the PMDI 8 and the polyol 10th is sprayed onto the wood fibers 3.
- the Lots 5 and 6 if necessary in separate buffers 11 and 12 intermediately stored. These may be conventional wood fiber bunkers act.
- An intermediate storage is basically optional and does not have to be mandatory.
- a mixing device 13 the wood fibers 3 of the Batches 5 and 6 mixed together. With a suitable combination the streams of lots 5 and 6 may be the required mixing also by rolling a scattering head a scattering device 14 done. From the wood fibers 3 both Batches 5 and 6 becomes a fiber mat in the spreader 14 15, which is a preform of fiberboard produced here 18 represents. The fiber mat 15 is in a calibration device 16 calibrated, which is a cold pre-compression Prepress is. Subsequently, in a Hot press 17 a heat treatment from which the desired Fiberboard 18 results.
- the hot press 17 is not so to understand that the fiber mat 15 under application compressed by pressure. Rather, the plates are the Hot press 17 distance-controlled, even without a constant back pressure the fiber mat 15 to fiber plates 18 with a defined thickness get.
- the new process can be done with both a belt press as a hot press 17 as well as with a discontinuous working Hot press to be performed. It can be beneficial instead of or alternatively to hot contact surfaces also a Hot air heating or high frequency heating of the calibrated Fiber mat 15 provide. When warming over hot contact surfaces, it is advantageous to the surfaces of Sprinkle fiber mat 15 with water, so that on the hot Contact surfaces evaporating water heat also into the interior of the Fiber mat 15 transfers. This is especially beneficial if the fiber mat 15 is very thick, d. H. more than 40 mm thick.
- the following examples have in common that the PMDI used, d. H. the NCO group-containing binder component, a Had composition, as used in the wood-based panel industry is common.
- the second polyol component binder component was the already mentioned above mixture of one Part of diethylene glycol and one part of polyether alcohol of molecular weight 1000.
- As a mixing device 13 came a simple rotary drum for use.
- the mixing time of the two games 5 and 6 was 10 seconds.
- the temperature of the contact surfaces of Hot press 17 was set at 170 ° C. All% information is in weight%.
- the PMDI 8 was used in a proportion of 2.5% and the polyol 10 in a proportion of 1% based on atro wood fibers 3. After 240 sec. Dwell time of the fiber mat 15 in the hot press 17, a 100 mm thick fiber plate 18 was removed. The average bulk density of this fiberboard 18 was 80 kg / m 3 . Despite the very low compression of the wood fibers in this fiber board, the fiber board for an insulating material was perfectly stable and manageable.
- the binder proportions corresponded to Example 1. After 300 sec. Dwell time of the fiber mat 15 in the hot press 17, a 50 mm thick fiber plate 18 was removed. The average bulk density was 170 kg / m 3 . The flexural strength of the fiberboard 18 was 0.3 N / mm 2 . The compressive stress at 10% compression was 0.18 N / m 2 .
