Definitions
- the invention relates to a device for impregnating web-like material with thermosetting impregnating resin comprising a impregnating trough in which the web-like material is brought into contact with the impregnating resin, a supply line leading to the impregnating trough, through which the impregnating resin is introduced into the impregnating trough, a heating device which heats the impregnating resin.
- the impregnation of web-like material with thermosetting impregnating resin, together with the subsequent drying of the impregnated web-shaped material, serves to produce impregnates, such as are used individually or in the form of a laminate formed from such impregnates, for example for coating base bodies formed from wood-based material, for example during manufacture of panels for covering surfaces, for example floors.
- the web material is not only in the prior art, but also in connection with the present invention, in particular a formed of natural fibers and / or synthetic fibers composite into consideration, for example, a scrim, a mat, a fabric or the like.
- the web material is paper whose basis weight in the unimpregnated state can be between about 25 g / m 2 and about 300 g / m 2 .
- the paper layer of an impregnate intended to form a visible surface of the end product may be printed with a desired décor.
- the impregnating resin is mixed with a solvent, for example water, whose function is to lower the viscosity of the synthetic resin.
- the impregnating liquor thus formed may, if desired, be admixed with further additives, for example a hardener.
- the finished impregnated web material must be dried before further processing, ie the solvent must be removed from the impregnate again, so that of the impregnating liquor only the impregnating resin remains in the finished product.
- the web material is impregnated with impregnating resin or that impregnating resin penetrates into the web material
- the web material is impregnated with impregnating liquor or that the impregnating liquor penetrates into the web material.
- the end product ultimately it is only important that the impregnating resin has also penetrated the web material and remains there during subsequent drying.
- the solvent which is based on a given amount of resin and has to be additionally added to reduce the viscosity, must again be removed from the impregnated web-like material in the subsequent drying step. This costs energy and time and thus in turn contributes to an increase in the cost of the impregnate. Overall, therefore, there is no cost advantage.
- the increase in temperature are also limited in practice. Namely, the impregnating resin cures faster at a higher temperature, that is, polymerizes faster. However, the higher the molecular weight of the resin, the worse it penetrates into the web-like material and the worse the finished impregnate can be further processed later. Thus, for example, at a temperature of the impregnating trough of more than 35 ° C., the liquor life is reduced so much that, in the event of a production interruption, the impregnating liquor would become unusable so quickly that disposal of the entire impregnating liquor present in the production plant, ie in particular in the impregnating trough, becomes necessary would. Of course, this is not tolerable.
- thermosetting impregnating resin it is therefore an object of the present invention to develop a device of the generic type such that the impregnation of sheet material with thermosetting impregnating resin can be made more effective.
- the heating device is associated with the feed line and heated the impregnating resin in the feed line.
- the impregnating resin is no longer heated in the impregnating trough, but in a heating device upstream of the impregnating trough.
- the wall surfaces of the impregnating trough no longer need to be used as heat exchanger surfaces for heating the impregnating resin, so that the risk of formation of coatings on these walls is at least reduced, if not completely excluded.
- the impregnating resin more precisely the impregnating liquor, the impregnating trough at a higher temperature, particularly a temperature of between about 50 0 C and about 80 0 C, and thus to supply lower viscosity than was possible in the prior art.
- the impregnating liquor may also contain less solvent and, due to the elevated temperature, have a viscosity which corresponds to that of a prior art impregnating liquor with a higher solvent content and lower temperature. This allows the subsequent drying to run more effectively.
- these two effects can also be used together.
- the impregnation process is carried out Use of the impregnating device according to the invention run off more effectively.
- the impregnation process itself is faster, thereby increasing the amount of sheet-like material impregnated per unit time.
- the drying of the impregnated web-shaped material can be done faster and with the use of less energy.
- the heating device is a non-contact heating device.
- the heating device can heat the impregnating resin, for example using microwave radiation.
- a control device which ensures that the heating device is supplied only to the amount of impregnating resin required for impregnation.
- the control device may operate in response to the detection signal of at least one sensor detecting at least one operating parameter of the impregnation device, for example, depending on the engine speed, i. depending on the speed with which the sheet material is fed to the impregnating trough.

This makes it possible to use a first part-tub for pre-impregnation and a second part-tub for main impregnation, wherein the impregnating resin can be kept preferably only in the first part-tub at the elevated temperature compared to the prior art, while in the second part-tub at a temperature which corresponds, for example, to the temperature used in the prior art.
- a first sub-trough connected to the feed line to have a smaller volume than a further sub-trough arranged further downstream in the flow direction of the resin.
- a further cooling unit is arranged between the two sub-wells.
- the further cooling unit can be assigned to a third part trough serving as a transition part trough, wherein this transition part trough, for example, can still be added to the preimpregnation step.
- the receiving volumes of the plurality of sub-troughs can be formed separately, in such a way that on the one hand a transition of impregnating from an upstream sub-tub to a downstream sub-tub can be done, but on the other hand, a transition of impregnating from a downstream sub-tub to an upstream part trough is not possible.
- a spraying device which moistens the sheet-like material, for example with water, preferably hot water or steam.
- the use of the impregnating device according to the invention enables the impregnation at a significantly higher solids content of the impregnating liquor, which can be saved in the subsequent drying considerable amounts of energy or allow existing drying capacities higher production speeds. For example, it is possible to work with a solids content of about 60% of impregnating resin in the impregnating liquor.
- aminoplast and phenoplast resins are usually used as impregnating resins.
- the following resins may, for example, be considered as impregnating resins: urea-formaldehyde resin, melamine-formaldehyde resin, melamine-urea-formaldehyde-resin (MUF), melamine-urea-phenol-formaldehyde-resin (MUPF), phenol-formaldehyde- Resin (PF), tannin resins, resorcinol-formaldehyde resins, silicone resins.
