Definitions

  • the invention relates to a device for connecting two substrate surfaces, comprising means for moving the substrate surface relative to at least one Coating nozzle with a nozzle opening, means for supplying a reaction adhesive to the at least one coating nozzle, means for applying of the reaction adhesive from the at least one coating die on the substrate surface, and means for pressing the two substrate surfaces together.
  • reaction adhesives are adhesives that undergo a chemical crosslinking reaction harden and here the necessary for a bond cohesive and build adhesive forces between the substrates to be bonded.
  • Reaction adhesives are both as one-component adhesives as Also known as two- or multi-component adhesives.
  • component Reaction adhesives crosslink, for example, under the influence of ambient air or the humidity contained in the ambient air. You need to therefore, before application to the substrate in a suitable manner, e.g. under inert Atmosphere are saved.
  • Multi-component reaction adhesives are only shortly before the bonding process of several components mixed together, which react with each other and thereby create networking.
  • Reaction adhesives have over other adhesives, such as Hotmelt adhesives, solvent adhesives or contact adhesives in in many ways superior qualities. Meanwhile, for example PUR reaction adhesives with high mechanical properties available, which are permanently transparent and therefore optically demanding Gluing suitable.
  • reaction adhesive In a gluing process, the reaction adhesive is usually first applied in the liquid state to one or both substrates, and Subsequently, the two substrates are pressed together. The adhesive subsequently hardened by crosslinking of the adhesive and leads to a firm connection of the two substrate surfaces.
  • reaction adhesive After application of the reaction adhesive to the substrate is regular only a limited time (so-called "pot life") for further processing, ie Pressing on or similar, available. Air hardening reaction adhesives are applied to extend the pot life in a thick strand, to the diffusion of atmospheric oxygen or humidity in the adhesive strand to delay and thus slow down the networking.

  • the reaction adhesive forms drops or beads with a certain diameter. This diameter is greater, the higher the viscosity of the adhesive is. As the viscosity of currently available standing reactive adhesives does not fall below a certain value, Consequently, the adhesive is in the form of larger drops or a bead applied the adhesive surface and when pressing the two substrate surfaces then occur the problems mentioned above.
  • An application of the adhesive, where the viscosity and surface tension not achieved this adverse effect can, by the coating in the semi-contact mode or in contact mode.
  • nozzle opening has a such distance from the substrate surface to be coated has the Distance of the nozzle opening edge is smaller than the diameter of the drop or the bead, the viscosity and / or the surface tension the adhesive and the dimension of the nozzle opening accordingly would train.
  • contact mode and semi-contact mode often occur side by side, So time-shifted to each other and take turns, because even then, if a coating in contact mode is desired, a short term greater spacing between nozzle opening edge and substrate surface, and thus a semicontact mode may occur.
  • a coating in contact mode is desired, a short term greater spacing between nozzle opening edge and substrate surface, and thus a semicontact mode may occur.
  • Viceversa can then, if one Coating in the semi-contact mode is sought, possible for a short time and transiently contact between nozzle orifice edge and substrate occurs.
  • the quality of the coating does not have to be adversely affected can be, because in both the contact mode and in the semi-contact mode the advantages of the invention can be achieved.
  • the distance between the nozzle opening edge and substrate is controlled so regulated or fixed, that at no time during the coating process a distance greater than that of the viscosity occurs and / or the surface tension of the adhesive and the dimension of the Nozzle opening resulting diameter of a job bead or a drop of the order.
  • an adhesive layer is applied to the substrate surface, whose Layer thickness compared to the otherwise forming thickness in the order as Drop or caterpillar is less. It will be at the same time as the order of the adhesive achieved and thereby already a uniform coating achieved the substrate surface, which causes the problems of incomplete Glueing or squeezing excess adhesive avoided can be.
  • the distance of the nozzle opening from the one to be coated must be Substrate surface as a function of viscosity and / or the surface tension and the dimensions of the nozzle opening are selected. Basically, with a low viscosity of the adhesive is a lesser Spacing required as at a higher viscosity to get a coating in semi-contact mode. It is still with a small nozzle diameter a smaller distance of the nozzle opening from the substrate surface required as a large nozzle opening to a coating in the semi-contact mode to achieve.
  • the Coating nozzle For adjusting the distance of the nozzle opening from the substrate surface is the Coating nozzle expediently in a direction approximately perpendicular to Substrate surface movable.

By the Heating the substrate surfaces between the pressing together and the Wrinkles produce increased elasticity of the adhesive. When appropriate even if the adhesive is selected to be viscous, it can be achieved be until a liquid state of the adhesive. This will be a certain relative movement of the two bonded together substrate surface during the folding process allows and thus avoided by the folding process Tensions are introduced into the substrate.
