Definitions

  • the present invention relates to a panel with a glue line, the glue line consisting essentially of a bonded glue, as well as an arrangement of panels with a glue line and a method for producing a panel with a glue line.
  • Panels with retaining profiles are known per se and can in particular be used as decorated wall or floor panels, the term wall panel also being understood to mean panels that are suitable for covering the ceiling or door. They usually consist of a carrier or core made of a solid material, for example a wood material, plastic or composite material, which is provided on at least one side with a decorative layer and a cover layer and optionally with further layers, for example a wear layer arranged between the decorative and cover layer .
  • the decorative layer is usually a printed paper that is impregnated with a resin.
  • the top layer and the other layers are also mostly made of resin.
  • Such known panels have holding profiles on the panel edges in a manner known per se.
  • the retaining profiles hold the panels together in the installed state by means of a form-fitting connection.
  • Various holding profiles are known.
  • Simple bungs have a simple groove and a complementary bung that act perpendicular to the plane of the panel.
  • More complex retaining profiles are known in particular for panels for glueless installation.
  • the complementary retaining profiles of two are closed connecting panels designed so that the form-fitting connection by hooks and undercuts also prevents the panels from being pulled apart. The panels can therefore be laid floating, so they do not have to be glued to the floor, and they also do not have to be glued together.
  • the laying of such panels is particularly easy and quick and the laid floor can also to a certain extent adapt to unevenness in the floor due to the flexibility of the connections and also react to temperature fluctuations.
  • the panels are laid without glue, they can easily be replaced if they are damaged.
  • the moisture protection of such panels may therefore still offer potential for improvement. There is potential for improvement in particular in the longevity of the moisture protection and in the simplicity of the use of a moisture protection.
  • the invention proposes a panel with a cord of glue, the cord of glue essentially consisting of a bonded glue.
  • the panel comprises a panel upper side and a panel lower side as well as at least four opposite panel edges in pairs, with complementary retaining profiles provided in pairs on the opposite panel edges, the retaining profiles being designed so that further panels with complementary retaining profiles can be attached to a retaining profile of a panel, at least one Holding profile has a cord of glue at least partially along its longitudinal axis, the cord of glue consisting essentially of a bonded glue.
  • the term “panel” is to be understood as meaning in particular wall, ceiling, door or floor panels. These can have a decor that is applied to a carrier plate and replicates a decor template.
  • Decorative panels are used in a variety of ways both in the area of interior design of rooms and for the decorative cladding of buildings, for example in trade fair construction.
  • One of the most common areas of application for decorative panels is their use as flooring.
  • the decor panels often have a decor that is intended to simulate a natural material.
  • glue line is to be understood as an elongated device which can hydraulically seal two surfaces lying against one another.
  • glue is to be understood as meaning an adhesive, that is to say a substance which is suitable for joining materials through surface adhesion and its internal strength (cohesion).
  • set is to be understood as meaning the state of the glue after setting, that is to say after a transition from the liquid to the solid state. This term includes all possible types of this transition, including drying by evaporation of the solvent, solidification by cooling a melt, or a chemical reaction. In particular, setting is understood to mean the achievement of cohesion of the glue.
  • panel edge is to be understood as the surface which connects the top of the panel to the underside of the panel.
  • retaining profile is to be understood as meaning the geometric configuration of the panel edge.
  • the term also includes multi-part retaining profiles.
  • complementary retaining profile is to be understood as meaning a retaining profile whose geometric configuration essentially complements that of another retaining profile.
  • a holding profile that essentially has recesses where the other holding profile has recesses, and vice versa.
  • Two complementary retaining profiles can therefore be fastened to one another in a form-fitting manner.
  • cavities can remain between the complementary retaining profiles.
  • a holding profile can have a groove and a complementary holding profile can have a bung, or a holding profile can have a hook and a complementary holding profile can have a corresponding undercut, or both holding profiles have hooks and undercuts.
  • a panel described above thus serves in particular to protect against penetration and penetration of liquids at panel joints.
  • a panel according to the invention comprises a panel top side and a panel bottom side as well as at least four panel edges lying opposite one another in pairs.
  • complementary retaining profiles are provided in pairs, the retaining profiles being designed in such a way that further panels with complementary retaining profiles can be attached to a retaining profile of a panel.
  • several such panels can be laid on one surface and connected to one another via the complementary retaining profiles.
  • the panels according to the invention are characterized in that at least one holding profile has a cord of glue along the longitudinal axis, the cord of glue essentially consisting of bonded glue.
  • the means for protection against penetration and penetration of liquids at panel joints does not have to be provided during laying.
  • the panels according to the invention can therefore be laid in exactly the same way as panels without a glue line, but at the same time offer improved protection against penetration and penetration of liquids at panel joints after laying.
  • the glue line does not create a permanent connection between the panels during laying, since the glue line essentially consists of set glue which has little or no adhesion with the complementary retaining profile of an attached panel.
  • the glue cord adheres exclusively to the holding profile which the glue cord has.
  • the glue is selected from the group consisting of dispersion glue, solvent glue, hotmelt glue, plastisol, polyaddition glue, polycondensation glue, and polymerization glue.
  • the glue can be applied particularly easily in the non-set state and can then be set particularly easily.
  • Dispersion adhesive and solvent adhesive can thereby advantageously partially penetrate into the surface of the retaining profile particularly well and thus develop good adhesion with the retaining profile during setting.
  • Dispersion adhesive and solvent adhesive can be set by drying. This results in particularly easy processing for the dispersion adhesive and the solvent adhesive.
  • Hot melt adhesives can advantageously be applied particularly precisely.
  • the viscosity of hot melt adhesives can advantageously be adjusted by means of a processing temperature.
  • the setting can advantageously take place by simple cooling and can therefore also take place particularly quickly. Hot melt adhesives are therefore also suitable for particularly fast production line speeds.
  • Plastisol, polyaddition adhesives, polycondensation adhesives and polymerization adhesives can advantageously set chemically. This makes these adhesives particularly durable. In addition, the mechanical properties of these adhesives can be adjusted particularly well.
  • the glue is selected from the group consisting of glutin glue, casein glue, urea-formaldehyde resin glue, phenol-formaldehyde resin glue, resorcinol-formaldehyde resin glue, low-formaldehyde polycondensation glue, formaldehyde-free dispersion glue (polyvinyl acetate glue), polyurethane resin unsaturated polyester resin, melamine glue, PMDI glue, and ethylene-vinyl acetate copolymer.
  • the glue described above makes it possible to achieve that the glue cord adheres particularly well to the holding profile and the glue can easily be set.
  • the glue has a water resistance, measured according to DIN EN 204, of at least D1, preferably at least D2, particularly preferably at least D3.

  • the glue has a setting time in a range from less than or equal to 1 hour to greater than or equal to 0.1 s, preferably from less than or equal to 1 min to greater than or equal to 0.5 s , particularly preferably from less than or equal to 10 s to greater than or equal to 1 s.
  • the glue can be processed particularly well to form the glue string.
  • good line times can be achieved in production as a result.
  • the glue is nevertheless easy to handle in its untied form.
  • the glue has a wettability, measured by the contact angle according to DIN EN 828, in a range from greater than or equal to 15 ° to less than or equal to 165 °, preferably greater than or equal to 25 ° up to less than or equal to 90 °, particularly preferably from greater than or equal to 35 ° to less than or equal to 55 °.
  • the glue line can be formed particularly well on the holding profile.

  • the glue line has a particularly great thickness, perpendicular to the surface of the holding profile.
  • the glue line extends particularly far away from the retaining profile and thus particularly strongly on a complementary retaining profile can press. A particularly good seal can thus be achieved.
  • particularly good adhesion of the glue line can be achieved with a particularly good seal by the glue line.
  • the set glue has a softening point measured according to DIN EN 1238 in a range from greater than or equal to 60 ° C. to less than or equal to 150 ° C., preferably from greater than or equal to 80 ° C. less than or equal to 130 ° C.
  • the glue has a viscosity at a processing temperature, measured according to DIN EN 12092, in a range from greater than or equal to 5000 mPas to less than or equal to 100,000 mPas, preferably greater than or equal to 10,000 mPas up to less than or equal to 50,000 mPas, particularly preferably from greater than or equal to 20,000 mPas to less than or equal to 30,000 mPas.
