Definitions

  • the invention relates to a method for sealing a gap and a sealing system for sealing a gap.
  • the object is achieved by a method for sealing a gap, in particular a joint between two walls, such that a sealant is used for sealing, which is covered after application with a film.
  • the basic idea of the invention is to protect the applied, not yet cured seal by means of a cover foil, so that it is guaranteed that emerging rain does not wash or rinse off the not yet cured seal.
  • the sealant used may in particular be a water-based sealant.
  • An aspect of the invention also provides that initially an insulating material is introduced into the intermediate space.
  • the insulating material may in particular be mineral wool.
  • the insulation between two spaces is improved, which are separated from each other by at least one of the walls.
  • a further aspect of the invention is that the film is fixed, in particular by means of an additional adhesive strip or an additional adhesive point or by an adhesive section formed on the film itself. By fixing the film can not be blown away in the wind, which would otherwise result in that the applied seal would be exposed to rain.
  • the sealant is applied by means of a spraying process.
  • the spray method is a particularly efficient method of making seals, as it can be machine-applied with simple sprayers.
  • Applicable sprayers may be, for example, airless devices. Further, the sprayers can be easily cleaned with water if a water-based sealant has been used.
  • the invention relates to a sealing system for sealing a gap, consisting of a sealant, in particular a water-based sealant, and a film for covering the applied sealant, in particular a waterproof, vapor-permeable film.
  • a sealing system for sealing a gap consisting of a sealant, in particular a water-based sealant, and a film for covering the applied sealant, in particular a waterproof, vapor-permeable film.
  • An aspect of the invention further provides that the film has a structuring, in particular a flocking.
  • the structuring of the film causes a drying-promoting property of the sealant, since the structuring of a capillary effect is achieved, which absorbs moisture from the sealant, so that it dries faster.
  • the film is composed of several layers, in particular at least one layer of fleece and a layer of a vapor-permeable functional membrane.
  • This combination provides a particularly suitable film, which is both waterproof and breathable or "breathable", so that the applied seal is protected from rain and at the same time hardens quickly.
  • a film is known for example from the field of outdoor clothing.
  • the invention provides that the film is elastic, in particular that the cured sealant and the film have similar elastic properties. Due to the fixation of the film, the film should preferably be made elastic, so that it can yield tensions or movements of the gap can follow. Due to the similar properties of foil and hardened seal it is also ensured that no tension can occur between the foil and the seal.
  • the sealant is a water-based polymer dispersion.
  • aqueous polymer dispersions which have proven particularly useful are aqueous acrylate dispersions, aqueous dispersions or emulsions of urea, formaldehyde or melamine resins, polyvinyl acetates, polyvinyl alcohols, acrylonitrile, styrene acrylates, polyurethanes and their copolymers, of which one acrylate dispersion a particularly favorable water-based sealant material.
  • the sealant from a fire barrier joint and the film consist approximately of a window sealing tape, wherein the window sealing tape in particular a membrane, such as a vapor diffusion open or - tradede polyester / polypropylene / polyester combination or a polyamide film with PET spunbonded, with one side applied Adhesive tape is.
  • window sealing tape in particular a membrane, such as a vapor diffusion open or - tradede polyester / polypropylene / polyester combination or a polyamide film with PET spunbonded, with one side applied Adhesive tape is.
  • the film is made of cured sealant to ensure that the elastic properties of the film and sealant are the same, thereby guaranteeing the prevention of tensions between the film and the sealant.
  • a sealing system 10 which is used for sealing a gap 12.
  • the intermediate space 12 is formed between a first wall 14 and a second wall 16, which are designed as a wall 14 and as a bottom 16.
  • the intermediate space 12 is thus a floor joint.
  • the sealing system 10 consists of a sealant 18, which is applied in such a way that the intermediate space 12 is sealed off at least at one side.
  • the sealing system 10 further comprises a film 20 which is secured by means of a first adhesive portion 22 at the bottom 16 and by means of a second adhesive portion 24 to the wall 14.
  • the second adhesive portion 24 prevents Unter Seriesen the film 20 by the running off of the wall 14 water.
  • the adhesive portion 22 may alternatively be omitted without deteriorating the tightness achieved by the film 20.
  • the adhesive portions 22, 24 are formed on the film 20.
  • the film 20 is doing over the applied sealant 18th stretched, so that the sealant 18 is protected. As can be seen from the figure, the film 20 does not touch the sealant 18.
  • the film 20 can be placed on the still moist sealant 18, so that the film 20, the sealant 18 partially touched (not shown), but this has no negative impact on the later functionality of the sealant 18.
  • the sealing system 10 may further include an insulating material 26 which is introduced into the space 12 to improve the insulation between a first space 28 and a second space 30, which are separated by the wall 16 from each other.
  • the sealant 18 is made water-based, so that the sealant 18 can be easily applied by machine in a spray process. However, the sealant 18 must dry to cure, which is why the film 20 is at least open to diffusion.
  • Water vapor which is deposited during the drying process of the sealant 18 from the sealant 18, can escape through the film 20 and escape into the first space 28.
  • the film 20 may be provided in various configurations, which cause a faster drying of the sealant 18. For example, this can be ensured by flocking or another structuring 32 of the side of the film 20 assigned to the sealant 18. Moisture escapes from the sealant 18 due to the surface tension of the sprayed-on, liquid sealant 18 and the interfacial tension of the structuring 32 of the film 20 faster.
  • the film 20 serves to protect the water-based sealant 18 from, for example, rain so that the sealant 18 will not be washed out when it is raining.
  • the film 20 is at least water-repellent from the side facing away from the sealant 18.
  • the sealant 18 is applied by means of a spray process, wherein the sealant 18 is applied to the bottom 16, the wall 14 and the insulating material 26 to ensure a functional seal of the gap 12.
  • the film 20 is water-repellent, so that the rainwater from the outside can not pass through the film 20. Furthermore, the film 20 is permeable, so that the still to be dried sealant 18 can dry out without moisture accumulates within the space 34 defined by the film 20 between the film 20 and the sealant 18.
  • the film 20 is attached by means of the two adhesive portions 22, 24 to the wall 14 and the bottom 16 so that the film 20 can not be blown away by strong winds.
  • the film 20 can also be attached to the wall 14 and the bottom 16 by means of adhesive dots, wherein the adhesive dots may be applied spray points of the sealant 18.
  • the film 20 may also be attached to the wall 14 and the floor 16 with additional adhesive strips. Furthermore, it is possible to place the film 20 on the still moist sealant 18, which can be dispensed with the additional spray points or the additional adhesive strip.
  • the film 20 when the film 20 is applied to the uncured sealant 18, adhesions may occur between the film 20 and the sealant 18, the film 20 preferably has similar elastic properties to the sealant 18, thereby ensuring that the film 20 and the sealant 18 a tension-free Form system. This ensures that the film 20 and the sealant 18 "work" or can change without the protective function of the film 20 is impaired.
  • the film 20 and the sealant 18 have elastic properties when the spaces 12 are irregular or move.
  • Such useful films 20 are typically known from the roof area for sealing the insulation. They also find application in the field of outdoor clothing. They also find application in the field of outdoor clothing.
  • a sealing method which combines all previous advantages and, moreover, can also be used in unfavorable weather conditions.
  • the drying time for the applied sealant 18 is only slightly increased due to the film 20, wherein the film 20 is also stretched only over the cured sealant 18 when rain is expected.
  • the inventive method thus represents a further development of the previously known from the prior art method, since this is also applicable, in contrast to the previous method, in unfavorable weather conditions.
