Definitions

  • the shelf life practically begins, and this is decisive for the optimal use of the reactive adhesive.
  • adhesives that crosslink with moisture the chemical crosslinking reaction is triggered by atmospheric moisture, but also by the constant action of temperature during the pre- and melting phase until application.
  • the object of the invention is to provide a method with which a reactive adhesive consisting of separately and indefinitely storable components can be achieved in one work step with immediately subsequent processing / application, with rejects of adhesive and thus additional costs being avoided.
  • the components of the reactive adhesive that is to say its components, are stored separately from one another so that they do not come into contact prematurely and, as a result, these components have an unlimited shelf life and storage time. As a result, the manufacturing processes are much simpler than before, based on the individual components.
  • the two or more components of the adhesive to be produced are added in solid or liquid form to an extruder, at least one component being metered in according to the adhesive mixing ratio.
  • the two or more components to be mixed are in a certain relationship to one another, which depends on the chemical structure and the later intended use of the adhesive.
  • the supplied components of the adhesive are placed in the extruder and heated by friction and pressure. The friction and pressure are sufficient to heat the adhesive. In addition, heating can also take place, which also comes into play later when the extruder mixing screw is restarted and stopped.
  • the extruder forms the pre-melter, which mixes the components in one pass and produces them into the ready-to-use and immediately processable reactive adhesive. 4 -
  • the cleaning process is also very simple, in that the reactive component (s) is (are) switched off and the other, non-reactive (s) component (s) is used to rinse the melting systems or application systems ( become) .
  • At least one adhesive component in solid form e.g. a granulate (G), or liquid form and at least one other
  • Adhesive component in solid form e.g. a granulate (G), or used in liquid form as a liquid (F). Both adhesive components are heated in a certain proportion in a conveyor line by pressure and friction and mixed together to form the liquid adhesive (K) and then the liquid reactive adhesive (K) is fed directly to the point of use (processing).
  • G granulate
  • F liquid
  • Both adhesive components are heated in a certain proportion in a conveyor line by pressure and friction and mixed together to form the liquid adhesive (K) and then the liquid reactive adhesive (K) is fed directly to the point of use (processing).
  • One adhesive component (G / F) is added to the other adhesive component (G) in doses.
  • One adhesive component is a non-reactive component and consists e.g. from a granulate (G).
  • the second adhesive component is a reactive component and is a granulate (G) or a liquid (F), and this second component (G / F) is meteredly added to the first adhesive component (G).
  • the two adhesive components can additionally be mixed under the influence of heat and / or the finished liquid reactive adhesive can be kept warm.
  • the non-reactive component is e.g. from functionalized polymers and resin mixtures and the reactive component e.g. from polyisocyanates.
  • the reactive component e.g. from polyisocyanates.
  • other reactive and non-reactive adhesive components can also be used.
  • This extruder (E) has a tubular - 6th
  • Housing (1) a mixing and conveying screw (2) which is set in rotation by a motor drive (3) arranged at one end of the housing.
  • the extruder (E) has a feed and feed hopper (4) mounted on the housing (1) for the non-reactive solid or liquid component, e.g. Granules (G), and a feed (5), such as a pipe or hose line, provided in the extruder working direction (A) behind the funnel (4), with a metering element (6), preferably a metering pump, for at least one reactive component in solid form , e.g. Granules (G) or liquid form (F).
  • An adhesive outlet (7) is arranged at the end of the extruder housing (1) opposite the drive (3).
  • the screw (2) of the extruder (E) forms the pressure and friction element for heating and mixing the adhesive components (G + F).
  • a heating device (8) can be assigned to the extruder (E).
  • An adhesive discharge (9) in the form of a pipe or hose line can be coupled to the adhesive outlet (7) of the extruder (E), through which the finished reactive adhesive (K) is applied directly to the processing point.
  • the reactive adhesive (K) is applied by all common application systems, such as syringes, doctor blades, rollers or nozzles.

Abstract

L'invention concerne un procédé et un dispositif permettant de produire des adhésifs réactifs à deux composants, tels que par ex. des adhésifs à réticulation sous l'effet de l'humidité. Selon ce procédé, on utilise au moins un composant non réactif de l'adhésif, sous forme solide, par ex. un granulat (G), ou sous forme liquide (F) et au moins un autre composant réactif, sous forme solide, par ex. un granulat (G), ou un liquide (F). Les deux composants sont chauffés par pression et friction dans une vis sans fin dans un rapport proportionnel déterminé et sont mélangés pour former l'adhésif (K) réactif liquide qui est appliqué directement au point d'utilisation (traitement).
