Definitions

  • the invention relates to a lightweight board according to the preamble of claim 18 and a method for their preparation according to the preamble of claim 1.
  • a generic lightweight board or a generic manufacturing process is made WO 01/07725 A1 known.
  • a lightweight board in which a core of at least two plates is covered on two of its sides.
  • This lightweight board has on its Lekssstimate a holding and end profile, which has a base part with a viewing or connection surface and one of these opposite cover surface and with an anchoring device which is arranged on the cover surface and engages in the assembled state in the core of the lightweight panel.
  • This retaining and closing profile is pressed into the longitudinal end faces of the lightweight board, wherein the core of the lightweight board is damaged at this point and the holding and closing profile is glued to the anchoring device arranged on the adhesive with the cover layers of the lightweight board.
  • Another lightweight board is in the DE 103 13 055 A1 described.
  • the method for producing this lightweight board should be characterized in that an adhesive layer is applied in the pass on a first side core layer and the first side of the core layer is combined with a first cover layer, applied to a second side of the core layer, an adhesive layer and the second side of the core layer is brought together with a second cover layer and the cover layers are pressed with the core layer.
  • this lightweight board arranged at least in the region of longitudinal end faces of the lightweight panel, can be arranged with the top layers glued frame latch.
  • the lightweight board described can thus be produced on the one hand without arranged on the longitudinal end faces frame latch, as well as with this longitudinal end side arranged frame bolts.
  • the lightweight board is thus built on the one hand with unprotected longitudinal end faces or on the other hand made with dimensioned on the cross section and the geometry of the lightweight board frame bars that cover the longitudinal end faces.
  • a disadvantage of this method is seen that the production should indeed work in a continuous, but each lightweight panel must be installed as a single piece step by step.
  • the invention provides the lightweight board according to claim 18 and the method for producing this lightweight board according to claim 1 ready.
  • the method for producing a lightweight panel according to the invention comprises a first method step, in which a groove is introduced into at least one longitudinal end face of the lightweight board, wherein in a second method step, a first profile strip is introduced into the groove of the lightweight board, in a third step via the groove of the Lightweight panel protruding profile strip is removed and in a fourth process step, a second profile rope is applied to the previously removed profile strip.
  • the first profile strip is made of a microporous foam structure.
  • the profile strip which is introduced into the groove of the lightweight board and removed, has a lower density than the subsequently applied profile strip.
  • the use of a thermoplastically processable material with a lower density positively influences the weight of the lightweight panel according to the invention; on the other hand, it has surprisingly been found that mechanical removal, such as, for example, milling off the part of the profile strip protruding beyond the groove of the lightweight panel , in the continuous process results in an enlargement of the surface of the profile strip, through which the subsequent application of a further profile strip can be realized fully automatically, quickly and cohesively.
  • Foam structure is exposed, which can be referred to as perforated-porous, so that the bonding of the subsequently applied profile strip, which generally has a decor analogous to the cover layers of the lightweight board, by the mechanical removal of the projecting over the groove of the lightweight board profile strip Penetration of the adhesive into the perforated-porous surface of the milled lower profile list is significantly improved. Due to this microporous structure, the profile strip on its surface openings, which are partially undercut. As a result, bonding qualities can be achieved which are comparable to the known bonds of, for example, thermoplastically processable edge strips on the longitudinal end faces of, for example, chipboard.

Due to the differently adjustable structured surface, which can be realized by various possibilities in the manufacturing process for the profile strip to be introduced into the groove of the lightweight board, such. B.
  • This primer system is selected from the group of polyolefins, polystyrenes, styrene copolymers, polyvinyl chlorides, polycarbonates, polyesters, polyamides, ethylene vinyl acetates or the like, wherein the primer system and an adhesive system used with the thermoplastically processable materials of the moldings can be adjusted so that an optimal Bonding quality and optimal appearance of the lightweight panel according to the invention can be realized.
  • the primer system can be used only when needed and dimensioned accordingly.
  • the profile strip to be introduced into the groove of the lightweight board can be made of a recycled thermoplastically processable material, which further positively influences the cost and economic efficiency of the lightweight board.

  • the surface of the profile strip introduced into the groove of the lightweight board for optimizing an adhesive bond by, for example, a flame treatment, a corona discharge, a plasma treatment, but also a primer coating can be optimized, so that a targeted activation of the surface of the profile strip takes place.
  • the profile strip, which is to be applied to the profile strip introduced in the groove of the lightweight board has a corresponding surface activation on its surface facing this profile strip in order to optimize the adhesive bond.
  • Another advantage of the lightweight panel according to the invention is seen in the fact that the existing of a thermoplastically processable material profile strips in the known extrusion or coextrusion and produced economically on rolls with about 100 m in length are available, so that in the manufacture of lightweight board according to the invention a continuous and characterized by low machine downtime production is possible. Due to the advantageous use of existing from thermoplastically processable moldings the longitudinal end faces of the lightweight panel according to the invention can be quasi sealed, as a double closure is carried by the two applied moldings. The profile strips themselves are moisture insensitive due to their material-specific properties, do not swell and do not corrode, so that this affects the lightweight board according to the invention in their intended use accordingly positive and different from the prior art.
