Definitions

  • the invention relates to a two-component pressure can with a frame, a dome, a valve arranged in the dome, a concave base, an upper and a lower chamber for a first and a second component, which are separated from one another by a separating element, and an im Floor arranged and operable from the outside opening device that runs through a passage in the floor and upon actuation eliminates the separation between the chambers for the first and second component.
  • the pressure can is particularly suitable and intended for the storage and dispensing of two-component systems, for example assembly foams with a hardener and/or filler component.
  • the invention relates to the formation of pressure cans which, in addition to the substances of the main component, accommodate a second component which reacts with the main component to form the finished product, a multi-component system.
  • Such systems are used in particular in assembly and insulation technology, for example when foaming in door and window frames, when foaming in wall openings and gaps, in sound and heat insulation, as well as in the production of foams that have fire-retardant properties due to mineral additives receive.
  • two-component systems can be used for the production of two-component paints and two-component adhesives.
  • the main component substances contained in the pressure vessel are liquid and, in the case of an assembly foam, comprise, for example, a polyurethane prepolymer with terminal reactive isocyanate groups. Other common substances are usually present.
  • the main component contains furthermore, a liquid gas component, which serves to expel and foam the contents of the can.
  • the liquid gas component also serves as a solvent.
  • the second component contains, in addition to other components, a crosslinking agent that is able to react with the reactive isocyanate groups of the main component.
  • a crosslinking agent that is able to react with the reactive isocyanate groups of the main component.
  • This is usually a substance with reactive hydrogen atoms, such as water or a polyol.
  • the reaction with the main component takes place immediately after the components are combined, so that the application of the mixture must start immediately after the two components have been mixed.
  • the reaction and foaming with the help of the propellant gas lead to the formation of the more or less rigid assembly foam at the point of use.
  • the second component of a two-component pressure can is held in a separate sleeve which is arranged at the base of the pressure can and can be activated through the base by a triggering mechanism.
  • a triggering mechanism This is done, for example, by a ram that protrudes into the inner sleeve from the outside and is pushed against the cover of the inner sleeve and blasts off this cover.
  • the contents of the inner sleeve can be mixed with the contents of the can by shaking and the product mixture, which has then already reacted, can be discharged.
  • An example is on the US3727797 or the
  • these inner sleeves have proven themselves, but they have the disadvantage that the inner sleeve does not offer enough space for a voluminous second component.
  • a second component for example a fire retardant contained in a carrier liquid.
  • flame retardants mostly of a mineral nature, such as graphite or hydrated aluminum oxide, have proven to be incompatible with the prepolymer, so that they can only be added to the main component immediately before the pressure can is emptied.
  • the second component also contains a crosslinker and other customary additives.
  • the search is therefore on for a two-component pressure can that allows larger quantities of a second component to be accommodated in such a way that the two components are strictly separated from one another during storage, but can be brought into contact with one another and thoroughly mixed before the pressure can is emptied.
  • a two-component pressure can of the type described at the outset in which the separating element between the chambers is a piston which is slidably mounted in the pressure can and has at least one opening closed by a closure element, and the opening device has an opening element which is suitable to separate the closure element from the at least one opening of the piston.
  • the two-component pressure can according to the invention is primarily intended for the application of assembly foams with a hardener and/or filler component, with the filler component being a fire retardant such as graphite, but also a mineral additive to influence the foam properties.
  • the filler component being a fire retardant such as graphite, but also a mineral additive to influence the foam properties.
  • such two-component pressure cans are also suitable for two-component paints, two-component adhesives and other two-component systems which are stored in a pressure can and are released from a pressure can under reaction.
  • the distribution of the two components to the two chambers is arbitrary and can be made according to the respective requirements.
  • the invention allows the volumes of the upper and lower chambers to be matched to the needs of the particular application. Almost any mixing ratio of the first to the second component from 10:90 to 90:10 by volume is easily possible. The adjustment of the pressure cell required for this does not require any major technical effort; only the length of the opening element has to be varied for this.
  • the pressure can according to the invention has, in a conventional manner, a dome with an inserted valve, a frame and a base fitted and arched into the frame.
  • An opening for the opening device which can be actuated from the outside via a trigger, is arranged centrally in the floor.
  • a piston that can be moved in the vertical direction is arranged in the frame, which divides the pressure cell space into a lower and an upper chamber.
  • the piston which is movably fitted into the body to divide up the interior of the can, is adapted to the body wall in a sealing manner in its edge region.
  • it expediently has at least one flexible sealing lip on the wall side.
  • a preferred embodiment provides two dovetail-like sealing lips, which are guided in a spread-apart form on the frame wall.
  • the sealing lips delimiting the upper and lower chambers can be embodied symmetrically or asymmetrically; the length of the sealing lip delimiting the lower chamber is in particular dimensioned such that it strikes the bottom of the can when the aerosol can is completely empty.
  • the piston can also be made of metal, such as tinplate or aluminum.
  • the seal to the inner wall of the can can take place here, for example, via a sealing ring or the sealing lip system described above.
  • the sealant is glued to the outer piston wall, for example.
  • the piston of the pressure cell can be guided with its wall on the inner frame wall, in order to create a tight seal for example, one or more O-rings are provided. These O-rings are conveniently located in indentations that run annularly around the outer wall of the piston.
  • the piston serves as a separating element between the chambers for the first and the second component.
  • it has at least one opening closed by a closure element, expediently arranged centrally in the middle of the piston or, in the case of several openings, around the middle of the piston.
  • the closure element for the opening can be opened via the externally operable opening device before the can is used, the opening device separating the closure element from the piston and thus releasing the passage between the two chambers.
  • the two components can basically be mixed in the chambers by shaking the can, which is usually only about 75% full.
  • Balls or rods, for example made of metal or ceramic, introduced into the pressure cell can promote the mixing process.
  • an opening device which is suitable not only for separating the closure element from the piston, but which can also simultaneously move the piston towards the bottom of the can and thus bring about a forced mixing of the contents of the chamber.
  • the opening device is arranged on the bottom of the pressure can and can be actuated from the outside through the bottom.
  • the closure element is expediently a membrane, a cover or a plug, preferably a plug which is fitted into the at least one opening from the underside of the piston.
  • the closure member is a plug which fits into the at least one opening from below, i.e. from the lower chamber, and can be pulled out.
  • the opening element of the opening device can be, for example, a pull rod, a pull strap, a pull cable or a pull wire.
  • a pull wire that is guided through the bottom of the can and can be actuated from the outside is preferred.
  • the pull wire and pull rod serve both to separate the closure member from the plunger and to move the plunger down towards the bottom of the can.
  • the opening mechanism needs two stages for this. In a first stage, the closure element is released from the piston and the passage between the chambers is thus released. In the second stage, the piston is pulled downwards towards the bottom of the can by means of the opening element, which causes the contents of the lower chamber to flow into the upper chamber and there to mix with the contents of the upper chamber.
  • the opening element protrudes outwards through the bottom of the pressure cell and can be operated from the outside.
  • the opening element is preferably a pull wire which is equipped with two catches in the terminal area.
  • the pull wire extends through the floor into the lower chamber and through the closure member into the upper chamber.
  • the first driver is located in the upper chamber in the end region of the pull wire, the second driver is spaced below the piston roof but above the stopper arranged under the piston.
  • a tie rod can be designed accordingly.
  • the opening device is located in the bottom area of the pressure can and, in addition to the opening element, also includes, in particular, a sleeve for the Opening element, which is anchored in a base plate in the concave base of the pressure can and has the necessary sealing elements for the passage of the opening element through the base.
  • the opening element expediently has a handle outside of the pressure can, which activates the pressure can when it is pulled.
  • the handle can easily be arranged in the concave bottom of the pressure can.
  • the piston arranged in the pressure can preferably has a cup shape, which is adapted to the dimensions of the opening device arranged on the bottom of the can. In this way, the contents of the pressurized can located in the lower chamber can be almost completely mixed with the contents of the upper chamber. At the same time, damage to the opening mechanism on the bottom of the can is ruled out during the critical activation phase.
  • FIG. 1 shows in longitudinal section the lower part of a pressure cell according to the invention with the piston and the opening device.
  • the upper part not shown, has a conventional structure and largely corresponds to the upper part of the WO 85/00175 A described pressure cell.
  • the pressure can according to the invention differs from this prior art in that the second component is not accommodated in an inner sleeve at the bottom of the can, but in a second chamber below the movably arranged piston.
  • the two-component pressure can 1 consists of a frame 2, a dome (not shown), a valve arranged in the dome (also not shown), a concave base 3 and an opening device 4 that can be actuated from the outside through the base.
  • the opening device 4 consists of a pull wire 5 , one crimped into a bottom plate 6 Passage element 7, a handle 8, which is arranged below the bottom 3 and is located outside of the pressure cell 1, and two drivers 9 and 10, which are in the upper area (valve-side area) of the pull wire 5 are located. These drivers 9 and 10 are firmly connected to the pull wire 5 .
  • the piston 11 which divides the interior of the pressure cell 1 into a lower chamber 12 and an upper chamber 13 .
  • the outer edge of the piston 11 is formed by 2 sealing elements 14a and 14b, which fit snugly against the inside of the can body 2.
  • the sealing lips 14a and 14b are spread like a dovetail and are supported on the inner wall of the can body 2 in a sealing manner.
  • the piston 11 itself consists in its central part of a cup-shaped structure 15 with a roof 16 and laterally extending rim or collar 17 terminating in the sealing lips 14a and 14b. Disposed within the roof 16 are openings or apertures 18, two of which are shown. Others may extend concentrically around the center of the bulb.
  • the openings 18 are closed by a plug 19 which projects into the piston 11 from below and has a plurality of pins 20 .
  • a pin 20 is provided for each opening 18 .
  • These pins 20 are fitted in a sealing manner into the openings 18 so that the first component contained in the upper chamber 13 cannot pass into the lower chamber 12 or the second component contained in the lower chamber 12 into the upper chamber 13 .
  • the pull wire 5 is guided firstly through the cover 19 and secondly through the roof 16 of the piston 11.
  • the passage through the roof 16 is designed to be sealed, so that the components contained in the two chambers are not exchanged here either can.
  • a seal is brought about in any case by contact of the components in the area of the passage through the roof 16 .
  • the pull wire 5 has the drivers 9 and 10 spaced apart from one another, with the upper driver 9 being in the upper chamber 13 and the lower driver 10 being in the lower chamber 12, but above the plug 19 in a recess.
  • the distance between the drivers 9 and 10 is such that when the pressure cell is triggered via the pull wire, the cover 19 is first pulled off the openings 18 so that the path between the two chambers 12 and 13 becomes free. Only in a second stage, when the pull wire 5 is pulled out further, is the piston 11 moved in the direction of the bottom 3 of the can. This reduces the volume of the lower chamber 12 in favor of the upper chamber 13, which forces the contents of the lower chamber 12 into the upper chamber 13.
  • the large number of openings 18 causes a good distribution and mixing of the second component contained in the lower chamber 12 in the upper chamber 13.
  • the cup-shaped design of the piston 11 takes into account the shape of the opening 7 of the opening device 4 arranged in the bottom 3 of the can. This ensures that the lower component is largely emptied of residues into the upper chamber 13 .
  • the passage 7 of the opening device 4 is crimped into a base plate 6 which in turn is crimped to the base 3 of the pressure can 1 .
  • the passage contains at least one sealing element 21 which prevents liquid from escaping from the lower chamber 12 to the outside.
  • This sealing element can, for example, be in the form of a rubber stopper 21 which has a central bore and tightly encloses the pull wire 5 .
  • the passage 7 has a spring element 22 which, after the release of the pressure cell, is intended to resiliently catch the cover/piston that has been pulled down.
  • the frame 2 of the box 1 can be made of aluminum and in this case has no seam. In this case there is no sealing problem between the piston and skirt. With welded cans, however, unevenness can occur in the area of the weld seam, which is why in this case it can be useful to paint the inside of the can, which is known per se.
  • the pressure can according to the invention can be stored for a long time in the non-activated state because the two components in the chambers 12 and 13 are hermetically sealed therein.
  • the pressure cell is only activated when it is triggered.
  • the pull wire 5 is pulled downwards with the aid of the handle 8, which in a first step releases the stopper 19 and, in a second step, moves the piston 11 via the driver 9 to the bottom 3 of the can 1.
  • the piston 11 has been pulled towards the can bottom 3 by means of the guide wire 5 and the driver 9 and is in its lowest bottom position.
  • the driver 9 rests directly on the piston roof 16 .
  • the lower chamber 12 is reduced except for a residual volume in the area of the piston cup 15, the contents of the lower chamber 12 flows (arrows) into the upper chamber 13.
  • the cover 19 is separated from the piston roof 16 and has the openings 18 uncovered.
  • the sealing lips 14a and 14b are also in their lowest bottom position; however, they no longer have any function at this point in time. However, the lower sealing lip 14b, with its stop on the lower end of the body 2 or on the can base 3, ensures that the piston cup 15 does not touch the opening device.
