Definitions

  • the invention relates to a skirting board with a wood material core, which is coated, preferably coated, with a plastic outer layer, in particular an extruded outer layer made of thermoplastic plastic.
  • the invention relates to skirting boards in which an adhesion promoter layer was first applied to the wood material core, preferably a hot melt adhesive layer was extruded on.
  • the invention further relates to a method for producing such a baseboard and a system for carrying out this method.
  • Such baseboards and such a method for their production are known from DE-AS 1 264 303 and EP-0 210 297-B1 from the applicant; in the latter, solid or plywood, as well as strips made of chipboard or hard fiber material are recommended as materials for the wood-based material core, and both known methods work with wood-based material cores with normal moisture content (e.g. 3 to 7 percent by weight of chipboard).
  • skirting boards produced according to these known processes also tend to form waves when laid - manufacturers currently stipulate that a skirting board should be used for all 20 to 30 cm firmly connected to the wall, eg nailed or screwed; Skirting boards are now installed e.g. in a room with high humidity or in a new building, the walls of which, as usual, have not yet dried out properly, water vapor diffuses through the plastic jacket into the wood-based material core, so that it lengthens and the skirting board is between its fastening points bulges away from the wall.
  • the invention had for its object to form a skirting board of the type mentioned in a cost-effective manner so that its tendency to form waves in the assembled state is reduced.
  • the wood material core consists of glued plywood or a wood material containing wood fibers and binders and the wood cells contain a quantity of water in excess of the natural water content of the wood material when the skirting board is installed.
  • the glued plywood is plywood.
  • skirting board In the skirting board according to the invention, a further increase in the moisture content of the wood-based material core in the installed, ie. H. in the assembled state of the skirting board almost impossible, even if this z. B. was mounted on a not yet dry new wall. If, on the other hand, due to the low humidity prevailing in a room, moisture diffuses out of the wood-based material core and through its coating over time, this does not lead to the corrugated skirting board becoming wavy, on the contrary, it will tighten against the wall because the wood material core then has a tendency to shrink, d. H. to shorten the skirting board.
  • a skirting board according to the invention not only has the advantage that it does not tend to form waves in the assembled state, but it also allows the distance between the attachment points of the skirting board on the wall to be increased considerably, in particular to about 60 cm, so that at save assembly time and time during assembly.
  • the wood cells of the wood material core contain a hygroscopic salt. This essentially serves to retain the increased water content in the wood-based material core.
  • skirting boards according to the present invention can now be produced without an additional operation, even at high production speeds Manufacture by first impregnating the wood material core with water or an aqueous solution of a hygroscopic salt in the continuous process, by applying a pressure difference across the wood material core to its direction of travel and adding the water or the salt solution on the higher pressure side, and then the outer layer of thermoplastic is extruded onto the wood material core before the elongation of the wood material core caused by the impregnation agent supply has reached its maximum.
  • an extrusion tool forming an all-round closed channel is advantageously used to apply the hot-melt adhesive layer, if present, and the outer layer, the channel cross section being adapted to the cross section of the finished baseboard
  • skirting boards according to the invention can be produced without the applied plastic layer (s) having unevenness as a result of vapor bubbles generated by the wood-based material core; in this context it seems to be essential that the water is introduced into the core of the wood material so shortly before the coating of the wood material core that a significant swelling of the wood material core could not yet take place; the water or the salt solution can only reach the cellumens in a short period of time, as a result of which no significant swelling is brought about, and only gradually does the impregnating agent diffuse from the cellulums into the cell walls.
  • the strip-shaped wood-based material core is not simply pulled through water or an aqueous solution of the hygroscopic salt used, but rather is pressurized with the pressurized liquid on the one hand and with a vacuum in a tool forming an all-round channel, whereby it itself a relatively high throughput speed of the wood-based material core succeeds in introducing sufficient amounts of water or the salt solution into the wood-based material core.
  • the aim of the present invention is, however, something completely different: apart from the fact that natural wood is not used for the core of the skirting board according to the invention, the continuous process is to be used and the impregnating agent is pressed or sucked into the wood-based material by applying pressure and a vacuum, the outer layer made of thermoplastic material and, if applicable, the hot melt adhesive layer should be extruded onto it immediately after the wood core has been soaked, as long as all of the impregnating agent is still in the wood material and before the wood core is elongated or has reached its maximum.
  • any hygroscopic salt or salt mixture can be used, but in accordance with the invention, common salt is preferred as the hygroscopic salt, not only because it is particularly cheap, but because it is has proven to be particularly effective in preventing unwanted elongation of the skirting boards.
  • the wood-based material core could only be soaked with water, but if you work with a salt solution, smaller amounts of soaking agent are sufficient to prevent the undesired length of the skirting boards, and the hygroscopic salt also has a permanent effect of the soaking effect. It is advantageous to heat the impregnating agent to, in particular, approximately 60 ° C., because this improves the absorbency of the wood-based material core.
  • the wood-based material core is briefly exposed to relatively high temperatures immediately before soaking, i.e. there is a shock-like treatment of the wood-based material core at high temperatures, as a result of which the absorbent capacity of the wood-based material for the impregnating agent can be increased considerably.
  • Temperatures between 150 ° C. and 350 ° C. are preferably used, in particular a temperature of approx. 300 ° C. It is advantageous if the wood-based material core is treated with water or a salt solution before the temperature treatment, e.g. rinsed or sprayed; Water vapor generated during the temperature treatment then penetrates into the wood material core and improves the absorption capacity of the wood material for the impregnating agent. The amount of water applied influences the absorption behavior of the wood material core in the impregnation device.
  • the invention relates to a system for carrying out the method according to the invention, and this system is characterized in that in the feed direction after a feed device for the wood material core and In front of an extrusion device for applying the plastic outer layer, a soaking device is arranged, which has a closed passageway for the wood material core except for an inlet and an outlet opening, the shape of which is adapted to the cross-sectional shape of the wood material core, and that two opposite walls of the flow channel are provided with openings for supplying the water or saline solution on one side and for applying a negative pressure on the other side.
  • systems were assumed, such as those shown in DE-AS 1 264 303 or EP-0 210 297-B1, ie. H. of systems which have an extrusion device for applying the plastic outer layer and, if appropriate, a hot-melt adhesive layer, and a feed device for the read-shaped wood material core arranged in front of the latter.
  • a preferred embodiment of the system according to the invention has a moisture meter between the impregnating device and the extruding device to determine the moisture content of the impregnating device determining the wood-based material core, in which case it is advisable to control the vacuum source and / or the impregnant quantity control device by means of the moisture meter.
  • a heating device for heating the wood-based material core in front of the soaking device, which is advantageously combined with a device for loading the wood-based material core with water.
  • Skirting boards with a hard fiber core are preferred, which have an average moisture content of approx. 10 to 25% (weight percent) when using water as an impregnating agent and from approx. 7 to 20% (weight percent) when using an approx. 20 to 28% solution hygroscopic salt (NaCl or NaCl-KCl mixture).
  • NaCl or NaCl-KCl mixture A mixture of NaCl and KCl in a ratio of about 70: 30% is preferred.
  • these values represent threshold values for the usually available qualities of hardboard strips, which should not be undercut to prevent damaging elongation of the assembled skirting boards; however, as is clear from the foregoing, these thresholds depend on the quality of the hard fiber material, and the moisture content can be somewhat reduced when using a saline solution.
  • the invention allows production speeds of at least 20 to 25 m / min. even if water is used as the impregnating agent instead of saline. Since such wood-based core strips are not homogeneous over their length, it should be pointed out that after the production of the skirting boards, a different moisture content in some areas is compensated for by diffusion.
  • the impregnation device has 36 bores with a diameter of 8 mm over a length of approx. 500 mm, i.e. around 7 holes per 100 mm length of the watering device.
  • this number is varied depending on the throughput speed of the wood-based material core.
  • the above-mentioned moisture meter is expediently arranged adjacent to that side of the wood material core strip on which the impregnating agent was sucked off in the impregnating device.
  • the heating device optionally combined with a water spray device (in the direction of passage) is expediently arranged in front of the feed device, although in principle it could also be arranged between the feed device and the impregnation device.
  • the process according to the invention is preferably carried out using an approximately 20 to 28% salt solution.
  • the length of the impregnation device and any heating device connected upstream of it depends on the throughput speed, i.e. depending on the production speed.
  • the impregnating agent content should be between approx. 10% (weight percent) and approx. 25%, but it can also be up to 30%; With an approx. 20 to 28% NaCl-KCl solution, which is particularly advantageous, an impregnant content of approx. 14% to approx. 18% is preferred in a hard fiber core.
  • FIG. 10 This shows on the right a magazine 10 for wood material core strips 12 which pass through the system in the direction of arrow A, so that each core strip passes through a water spray device 13, a heating device 14, a feed device 16, a soaking device 18 and an extrusion device 20 one after the other.
  • the magazine 10 is provided with feed rollers 22, each of which grips a core strip, and feeds the water spray device 13 and a channel 14a to the heating device, in which the wet core strip is exposed to a temperature of approximately 300 ° C. during the passage.
  • the core strip is then gripped by conveyor belts 16a and 16b of the feed device 16 and pulled off the heating device and inserted into a channel 18a of the impregnation device 18; in addition, the feed device 16 conveys the core strip through a channel 20a of the extrusion device 20.
  • the latter need not be described in more detail, since it can be an extrusion device as it is drawn and described in DE-AS 1 264 303 or in EP-0 210 297-B1.
  • an impregnating agent supply line 18b Connected to the impregnating device 18 forming the channel 18a is an impregnating agent supply line 18b in which a flow meter 18c is located and which leads to bores (not shown) in the upper wall of the channel 18a according to the drawing.
  • the opposite, lower wall of the channel 18a is also provided with bores to which vacuum pumps 18e are connected via suction lines 18d.
  • a moisture meter 30 is arranged between the impregnation device 18 and the extrusion device 20, adjacent to the underside of the continuous core strip 12, with which the moisture content of the core strips 12 is continuously measured without contact.
  • the moisture meter 30 and the flow meter 18c control a metering device, also not shown, in the impregnating agent supply line 18b and, if appropriate, the vacuum pumps 18e via a control circuit (not shown).
  • a vacuum of between 0.6 and 0.9 at is preferably applied via the suction lines 18d and the impregnating agent is supplied with an excess pressure of between about 0.3 and about 3.0 bar.
  • the wood material core strips 12 are preferably completely encased in the extrusion device 20 with the hot-melt adhesive layer and the outer layer made of a thermoplastic.
  • the system is advantageously provided with a processing device for processing the impregnating liquid.
