Definitions

  • the invention relates to a method for producing a multi-component cartridge, which serves for the separate storage and for co-pressing of at least two components of a flowable mass, wherein the multi-component cartridge has a cylinder with at least two separate chambers for separate storage of the components of the mass ,
  • the invention further relates to a multi-component cartridge for the separate storage and for co-squeezing of at least two components of a flowable mass, comprising at least one cylinder for receiving the mass, with at least one squeezing piston for squeezing the mass and at least one outlet opening for the mass, wherein the components of the mass are stored separately in at least two chambers of the cylinder, which extend in the longitudinal direction of the cylinder of the multi-component cartridge.
  • Under flowable mass is to be understood in particular a pasty material with pasty components, such as multi-component adhesives, multi-component resins or multi-component mortar.
  • Cartridges are used to spray adhesives or sealants and are used in cartridge presses for this purpose.
  • cartridges For storing and for pressing two-component masses cartridges are used which have a two-chambered cylinder in which the two components are introduced and stored separately from each other.
  • the components located in the chambers can be pressed together in a predetermined mixing ratio through the outlet opening.
  • the extruded components are mixed together in a static mixer attached to the outlet opening.
  • a two-component cartridge which has the shape and structure of a one-component cartridge and thus in Conventional cartridge presses can be used for one-component cartridges.
  • a cylinder of the known cartridge is divided into two chambers arranged next to one another by a flexible separating wall arranged in the longitudinal direction and materially connected to the cylinder and cartridge wall.
  • the flexible partition is successively separated from the cylinder and cartridge wall during extrusion of the components by the extrusion piston and received in a cavity of the extrusion piston.
  • cartridges are preferably made of polyolephine plastics. They have limited barrier properties against diffusion of water into or out of the cartridge, which does not suffice for hybrid mortar or PU systems, or requires a thick cartridge wall to reduce water vapor diffusion to a tolerable level. In such masses, water vapor diffusion plays a crucial role in the durability of the components of the mass stored in the cartridge because one of the components reacts with water, rendering the mass unusable.
  • the invention is therefore based on the object to propose a multi-component cartridge for separate storage and for coexpression of two or more components of a flowable mass, which largely prevents water vapor diffusion between the chambers of the multi-component cartridge and / or from outside into the cartridge which is inexpensive to produce.
  • the invention is also based on the object to propose a method for producing such a multi-component cartridge.
  • the cylinder need not have the shape of a geometric cylinder with a circular cross-section, but the cylinder is tubular (for example, a polygonal tube) with a constant over its length cross-section.
  • One possible embodiment of the multi-component cartridge according to the invention has a plastic cylinder which is subdivided with a film into two separate chambers for receiving two components of a flowable mass.
  • the film is materially bonded to the cylinder by the film is molded with the thermoplastic material of the cylinder.
  • a film of a size corresponding to the multi-component cartridge is provided in a first working step.
  • the film can be produced as a foil blank from a film tarpaulin or a film tube. Subsequently, the film is inserted into a longitudinally extending recess of a first part of a tool core of an injection mold for the cylinder of the multi-component cartridge.
  • the tool core is expediently removed from the injection mold and the film is inserted outside a mold space of the injection mold into the core.
  • a second part of the tool core of the injection mold is inserted into the recess of the first part of the tool core, wherein the second part of the tool core covers a part of the film, so that a part of the film rests between the two parts of the tool core.
  • an inner portion of the film is sandwiched between the two parts of the tool core and an outer portion of the film is located on an outer side of the tool core of the injection mold for the cylinder of the multi-component cartridge.
  • the exterior of the film is formed by edges of the film which protrude from the assembled parts of the tool core.
  • the edges of the film can completely or partially enclose the tool core or protrude from the tool core. It is also possible to coat the first or the second part of the tool core with a film tube, or to overlap the edges of a film strip around the tool core.
  • the composite tool core with the film is introduced into the mold space of the injection mold for the cylinder and the injection mold is closed.
  • the mold cavity surrounding the mold core of the injection mold is filled with thermoplastic material and the mold core and the outer region of the film protruding into the mold cavity are encapsulated with plastic, whereby the outer region of the film is firmly bonded to the cylinder.
  • the cylinder of the multi-component cartridge is removed from the mold and removed the parts of the tool core inserted in the cylinder from the multi-component cartridge.
  • An advantageous embodiment of the invention provides that in this method, a diffusion-tight film is used.
  • Ans arrangementsbeiituls inventive multi-component cartridge for separate storage and common pressing of at least two components of a flowable mass at least one cylinder, which is divided with a diffusion-tight film in at least two separate chambers for receiving the components.
  • the diffusion-tight film extends over the length of the cylinder, wherein an inner region of the film divides the cylinder into longitudinal chambers and an outer region of the film is encapsulated with the plastic of the cylinder.
  • the outer region of the film is materially connected to the cylinder and separates the stored in the chambers components of the multi-component cartridge from each other.
  • the film forms a diffusion barrier to water and / or water vapor and prevents moisture from entering the chambers and / or exiting the chambers.
  • the film may be made of metal or plastic or other diffusion-inhibiting materials. It is also possible to completely or partially line the chambers of the multi-component cartridge with the outer region of the film.
  • a film a film strip or a film tube can be used.
  • the film has a metallic layer as a diffusion barrier. Due to their low water permeability, metals are particularly suitable as a diffusion barrier against water vapor.
  • the metallic layer consists of aluminum, since aluminum is easy to work and inexpensive to procure. Aluminum is corrosion-resistant and largely chemically resistant. Other corrosion resistant metals can also be used.
  • the film can be made entirely of metal or have a metal layer on a carrier material.
  • the film is made of a composite material.
  • the composite material consists of a first layer of plastic and a second layer of metal arranged thereon.
  • the first layer of plastic does not necessarily have to be diffusion-inhibiting, since the Metal layer acts as a diffusion barrier. Due to its low water vapor permeability and the low cost of an aluminum composite film is particularly suitable.
  • a further advantageous embodiment of the invention provides that the inner region of the film is spaced from the cylinder, wherein the inner region forms a partition extending in the longitudinal direction of the cylinder.
  • the inner region of the film which is spaced from the cylinder, divides the cylinder into juxtaposed chambers extending in the longitudinal direction of the cylinder.
  • the chambers thus formed are used to hold different components of the flowable mass.
  • the inner area of the film forming the dividing wall is pressed or sheared from the inside onto the cylinder by the ejection piston and the components of the mass are pressed through the outlet opening.
  • a peripheral portion of the partition wall is at least as long as a corresponding peripheral portion of a chamber of the cylinder, to which the partition wall is pressed during the pressing of the components, so that the partition wall rests completely on the cylinder.
  • the film divides the cylinder of the multi-component cartridge into separate chambers extending in the longitudinal direction of the cylinder.
  • the cylinder may be divided into two or more chambers. Chambers that are completely enveloped by the film, have a particularly good diffusion protection.
  • the outlet opening of the multi-component cartridge on a cross bar on which the film is fixed with a front edge is sealingly, preferably materially, connected to the transverse web, which forms an intermediate wall of the outlet opening.
  • the intermediate wall can be flat or curved and can protrude with one end into the cylinder.
  • the intermediate wall keeps the components of the mass separated until the components have emerged from the outlet opening.
  • the intermediate wall of the outlet opening expediently extends to a front end of the outlet opening, whereby the chambers of the multi-component cartridge can be easily closed, for example, by screwing a closure cap onto the multi-component cartridge.
  • the chambers of the cylinder are sealingly closed on the side opposite the outlet opening by the extrusion piston.
  • This has the advantage that the chambers of the cartridge can be filled in one operation from the opposite side of the outlet opening. Due to large filling openings of the chambers on this side, large-diameter filling tubes can be used, which shortens the filling time.
  • the filling openings of the chambers are closed by introducing the extrusion piston.
  • the spaced from the cylinder inner region of the film is pressed by the extrusion piston against the cylinder, whereby the chambers are sealed against each other.
  • the extrusion piston is expediently designed so that the extrusion piston does not cut into the film when the components are pressed out. This can be achieved by appropriate shaping or material selection for the extrusion piston.
  • a shearing of the dividing wall forming film by the extrusion piston is also possible, but carries the risk of a reduction in the diffusion density in particular between the chambers.
  • inventive multi-component cartridge 1 is used for separate storage and common pressing of two components of a flowable mass and has a cylinder 2, a head 3 and a cylindrical extrusion piston 4.
  • an outlet opening 5 is formed, which has an external thread 6 for the adaptation of attachment elements, not shown.
