Definitions

  • the present invention relates to a sealing tape made of soft, compression-recoverable foam for sealing a joint, which is impregnated with an impregnate.
  • Such sealing tapes are usually made of polyethylene or polyurethane foam and serve to seal against rain, air, wind, sound or insulation against heat loss.
  • the sealing tapes are used in particular in the construction industry, where joints between the window or door frame and the masonry to be sealed.
  • the foams consist of a cell structure with cell stems and pores in between.
  • the range of flexible foams ranges from closed-cell foams, which provide virtually no air passage, to open-cell foams, which have a relatively high air permeability.
  • At least open-celled foams are usually soaked to achieve the desired sealing properties with an impregnate. Such impregnates also lead to a delayed recovery of the foam after its compression, since the impregnates usually contain adhesive substances that attach to the cell webs of the foam structure and adhere there.
  • the delayed recovery is often exploited in the sealing of joints by the foam is first compressed and inserted into the joint to be sealed, whereupon the foam expands by itself to a part-expanded functional state and closes the joint.
  • the impregnate can also achieve other positive properties, such as fire protection properties or protection against UV radiation.
  • DE 1 937 394 A discloses an insulation sheet, in particular insulation panels, insulation sheets or insulation moldings, for example, non-impregnated closed-cell foam. Incisions are made in the insulation track to increase air ventilation and make the foam semipermeable.
  • Impregnation with viscous impregnates is difficult to achieve even with open-celled foams. Completely closed-cell foams have so far been virtually impossible to impregnate.
  • the present invention is therefore an object of the invention to provide a sealing tape made of soft, recoverable after compression foam, which is impregnated in a particularly simple manner and at the same time achieves enormously high density values.
  • a sealing strip of rectangular cross-section of soft, resilient after compression foam for sealing a joint wherein the sealing strip is impregnated with an impregnate and provided with a plurality of cuts, which serve to receive and distribute the impregnate in the foam.
  • relatively closed-cell foams can be impregnated more easily and homogeneously, open-cell foams can even be impregnated with viscous impregnates, and even fully closed-cell foams can be provided with an impregnate in the area of the incisions by superficial adhesion, whereby the desired properties such as delayed recovery caused by the impregnate can be achieved are.
  • the incisions in the foam are arranged such that they do not affect the seal in the functional direction of the sealing tape or only insignificantly.
  • the sealing tape according to the invention has no disadvantages compared to a conventional sealing tape in this respect.
  • the extent of the incisions in the longitudinal direction of the sealing strip is at least as great as the extent of the incisions in the transverse direction of the sealing strip.
  • the sealing effect in the transverse direction of the sealing band is kept almost constant, while the total area of the incisions in the foam is maximized in the sense of optimum impregnation.
  • the cuts are distributed in regular patterns over the foam.
  • the incisions extend over the entire height of the sealing strip, whereby the manufacturing process can be made particularly simple.
  • the incisions from the top and the bottom of the sealing tape offset from each other are formed to a certain penetration depth in the foam.
  • the number of cuts in the foam can be further increased in a simple manner and thus the homogeneity of the impregnation of the foam can be improved.
  • the impregnate allows penetration at locations that were previously inaccessible.
  • a sealing tape with enormously high sealing values is achieved when the sealing tape according to the invention is formed from a relatively closed-cell foam with low air permeability.
  • the impregnate improves the sealing properties of the sealing tape and has tacky properties which result in delayed recovery of the sealing tape after its compression, resulting in easier handling of the sealing tape in the building sector.
  • the incisions are preferably formed as displacement cuts.
  • Fig. 1 a shows a plan view of a first embodiment of a sealing tape according to the invention.
  • the sealing band consists of a soft foam 2, which may be formed of a relatively open-cell foam material with high air permeability, but preferably consists of a relatively closed-cell foam material with low air permeability and small pore cross-sections. Even foams with air penetration values, which lie between the two extreme cases mentioned above, can be used in the context of the present invention.
  • Preferred foams are polyurethane or polyethylene foams, which recover completely or almost completely to their original state after compression.
  • the expansion of the sealing tape is in Fig. 1 a not faithfully reproduced, since the sealing tape usually has a much larger extent in its longitudinal direction and is wound into a roll. So far Fig. 1a merely as a section of the sealing tape according to the invention to look in the longitudinal direction.
  • Fig. 1a In the top view Fig. 1a can be seen many incisions 4a, which here introduced into staggered longitudinal rows in the foam 2, preferably were cut. As from the in Fig. 1b illustrated cross section along line II Fig. 1a it can be seen, in this particular embodiment, the incisions 4a are continuously formed over the entire height of the foam 2, thus establishing a connection between the top 6 and the bottom 8 of the sealing strip.
  • the distance between two longitudinal rows of incisions 4a is usually between 1 and 5 mm, as is the distance between two punctiform incisions 4a within a longitudinal row. With wide sealing tapes or sealing tapes with high height for sealing larger joints, even larger distances can be sufficient to achieve the desired effect.
  • an impregnate penetrates particularly easily into interior regions of the foam, so that even highly closed-cell foams 2 can be almost completely homogeneously impregnated.
  • the impregnate preferably has sticky properties, so that a delayed recovery of the foam 2 is achieved after its compression.
  • the waterproofing and rain-tightness are further increased by the impregnate.
  • the impregnate may also have fire-retardant properties and anti-UV properties. Conventional impregnates are e.g.
  • Fig. 2a and 2b illustrated second embodiment differs from the first embodiment in that the upper cuts 4b, which extend from the top 6 of the foam strip in the foam 2, extend only to about half of the height of the foam 2, while offset this identical cuts 4b protrude from the bottom 8 of the foam 2 in this up to half of the height. This makes it possible to realize lower penetration depths into the foam 2 and to ensure the impregnation of the foam 2 nevertheless.
  • a particularly advantageous third embodiment of the sealing tape is in Fig. 3a and 3b shown.
  • the difference to the embodiment of Fig. 1a and 1b is that the incisions 4c are extended in the longitudinal direction of the sealing band and thus form strip-shaped longitudinal sections.
  • the perforated portion of the foam 2 is increased in the longitudinal direction and achieved an excellent impregnation of the foam 2 with the impregnate.
  • the length of the individual strip-shaped longitudinal sections is usually in the range of a few millimeters, but in itself is almost arbitrary and, inter alia, dependent on the dimensions of the foam.
  • Fig. 4a and Fig. 4b show a fourth embodiment of the sealing tape according to the invention, which corresponds to the third embodiment, but in which the outgoing from the top 6 of the foam 2 incisions 4d, similar to in Fig. 2b , do not extend to the underside 8 of the foam, and instead project from the bottom 8 of the foam offset from the upper incisions arranged lower incisions 4 d in the foam 2.
  • the height of the individual cuts is arbitrary here.
  • the incisions can also protrude from only one side, for example the underside 8 of the foam 2, without completely penetrating it (penetration depth preferably between approximately 70 and 99% of the height of the foam), whereby a comb-like structure is formed.
  • a self-adhesive strip provided with a cover foil (not shown) is usually applied to the underside 8 for attachment to the component to be sealed. This self-adhesive strip can simultaneously serve to hold together the foam material remaining between the cuts 4a to 4d so that the foam 2 is kept in shape even during compression.
  • the structure of the cuts 4a to 4d is variable. Depending on the type of foam, a choice can be made among almost any number of patterns (holes, slits, Z patterns, waves, etc.). However, a greater extent of the incisions in the longitudinal direction is particularly advantageous with respect to the sealing properties of the sealing strip in the transverse direction, which represents the functional direction of the sealing strip.
  • the production process of the foam according to the invention preferably proceeds as follows. First, the foam material is produced in large layers, which are then provided with the cuts 4a.
  • the introduction of the impregnate takes place preferably by impregnation of the foam layers in a dip bath, wherein multiple compression of the foam layer in addition to the penetration of the impregnate into the incisions leads to a suction effect in the incisions into it. In the area of the incisions, the impregnate penetrates into the nearby cell pores as well as on the upper side 6 and the lower side 8 of the foam and deposits there.
  • a self-adhesive layer is applied and the large foam layers are wound in a compressed state onto wide master rolls. These master rolls are severed along with the foam wound thereon at desired intervals, thereby producing narrow-width sealing tape rolls.
  • the cuts 4a to 4d are preferably cut by means of suitably shaped knives as displacement cuts in the foam, but it is also conceivable to punch material from the foam or to form the cuts by means of a water jet cutting machine.
  • the sealing tape according to the invention thus provides outstanding sealing properties and can be produced in a simple manner.
