Definitions

  • the invention relates to a method for the production of a waterproof coating on a surface, and particularly to the production of a roof coating wherein a sheet material is rolled out and bonded to the surface in separate zones so as to form interconnected pressure relieving passages between the sheet material and the surface.
  • the purpose of providing such pressure relieving zones in a roof coating of e.g. roofing felt is to avoid the accumulation of moisture and air under superatmospheric pressure in restricted zones of the roof coating causing serious steam bulges in the roof coating.
  • a number of methods for the formation of pressure relieving passages in roof coatings are known. Thus, instead of applying bitumen all over the surface to be coated it may be applied in restricted zones by means of a broom, and subsequently the roofing felt may be pressed against the surface.
  • DE-OS No. 28 45 700 describes a roof coating material consisting of a layer of roofing felt, the under side of which is coated with a thick mat of coarse, elastic fibres, and preferably synthetic fibres, and comprising on the opposite side, which is intended to be contacted with the surface, separate zones of a binder such as a self-adhesive bitumen layer or a layer of a binder which can be activated by addition of a further component.
  • a binder such as a self-adhesive bitumen layer or a layer of a binder which can be activated by addition of a further component.
  • the known coating methods do not result in an optimum pressure relief because the adhesion is effected within relatively large adhesive zones separated by non-adhering zones. This is mainly due to the fact that the binders previously used spread during heating. Thus, there is a risk of the formation of steam/air bulges within the adhesive zones.
  • the object of the invention is to provide a uniformly adhered coating which not only is pressure relieving but also stress relieving over a wide temperature range.
  • This object is obtained by the method of the invention by using a sheet material comprising separate zones of a bituminous binder modified with 5-40% by weight of a thermoplastic elastomer.
  • the modified bitumen binder has various properties which makes it particularly suitable for use in connection with the method of the invention.
  • it can be applied mechanically in the form of small well-defined protrusions e.g. by means of a pattern roller.
  • steam/air bulges which may be formed within large zones coated with a binder between the surface and the coating may be avoided and the stress relief is dispersed over the entire surface.
  • the binder has the property of not spreading even at high temperatures, e.g. at temperatures of 70°C which may occur when the roof surface is subjected to sunlight. Also the binder maintains its elasticity at low temperatures.
  • the binder may be used for the production of coatings which are to be stress relieving at temperatures down to - 35°C.
  • the binder presents the advantage of being self-adhesive in the sense that it will bind to a dustless surface at temperatures down to 5°C when pressed against such surface.
  • the adhesion of the sheet material for certain compositions of the binder presupposes that the binder zones are heated prior to the application onto the surface.
  • the binding compositions have such a good interior cohesion and excellent adhesion to the surface that it is sufficient to coat 25-40% of the surface area of the sheet material even in the case of the coating being exposed to strong wind forces.
  • the thermoplastic elastomer is preferably a blokcopolymer based on polystyrene and polybutadiene or polyisoprene, and it is used, as mentioned, in an amount from 5 to 40% by weight based on the weight of the bitumen component.
  • the use of less than 5% by weight of elastomer results in a binder with a too poor flexibility, and the use of more than 40% by weight of elastomer makes the binder too viscous for mechanical application.
  • the binder may contain one or more resins such as petroleum resin and tall oil resin and one or more oils such as process oil and soya bean oil. Such resins and oils may be used to modify e.g.
  • bitumen component may be distilled bitumen or oxidized bitumen.
  • the application of the sheet material described above to the surface is effected in conventional manner.
  • the sheet material is covered with a plastic film, release paper or the like which is removed before application.
  • the removal may be effected by burning off the film, and following this step the zones coated with the binder may be superficially heated.
  • the sheet material is preferably pressed against the surface. This can be effected by means of squeezing rollers or by stepping on it to press it against the surface.
  • the invention also relates to a coating sheet material in the form of a roll, said coating material being characterized in that it comprises a large number of small separate zones coated with a bituminous binder modified with 5-40% by weight of thermoplastic elastomer.
  • the binder zones preferably are of a height of 1-3 mm, preferably 1.5 mm above the sheet material, thus making each zone function as a spacing element when the material has been applied to the surface.
  • Such relatively thick binder zones are suitable because as mentioned above the binder exhibits a relatively large stability with respect to shape within the relevant temperature range and thus does not spread.
  • the individual binder zones are preferably formed in such a way that they have an extension of less than 50 mm in at least one direction.
  • the sheet material coated with a binder for use in connection with the method of the invention may be manufactured by applying the binder in a molten state to the one side of the sheet material with a pattern roller.
  • the application of the binder in the desired pattern may be effected on sand coated or similarly treated roof sheets.
  • the binder zones Before the sheet material is wound up the binder zones must be covered which preferably is effected by applying thereto a thin plastic film e.g. a polyolefine film with a thickness ranging from 0.008 to 0.05 mm.
  • a thin plastic film e.g. a polyolefine film with a thickness ranging from 0.008 to 0.05 mm.
  • This film is removed before applying the sheet material to the surface.
  • the films are of a thickness of 0.008 to 0.01 mm the removal is preferably effected by burning off the film.
  • the coating sheet material of the invention is particularly suitable for use in the method of the invention. However, it may also be used in a coating comprising at least two sheet materials, the sheet material of the invention having the binder zones facing a superimposed sheet material.
  • a welding binder of the following composition was produced:
  • This welding binder was applied to a fibre reinforced coating sheet impregnated with bitumen and covered with a sand layer in rows of narrow stripes which extend parallel and in the longitudinal direction of the sheet.
  • the stripes were of a width of 15 mm, a length of 300 mm, and a thickness of 1.5 mm, and the spacing between the stripes was 30 mm.
  • the sheet was covered with a 10 ⁇ m thick protective film of polyethylene.
  • the coating material thus obtained had the following composition:
  • the sheet material thus produced was applied directly to a board surface primed with bitumen after removal of the protective film by burning and by superficially heating the binder zones.
  • the result was a stable, non-cracking coating which was suitable as surface for additional layers of roofing sheets.
  • a self adhesive binder of the following composition was produced:
  • the self adhesive binder was applied to a fibre reinforced coating sheet which had been impregnated with bitumen and coated with sand in the same manner as described in example 1 so as to form a roofing sheet material of the following composition:
  • the coating sheet thus produced was directly applied to a bitumen-primed supporting concrete surface with the protective film being removed immediately before the application of each sheets.
  • the coating sheet was also used in the coating of an existing roofing felt coating. Prior to the application to this surface steam bulges in the existing coating were perforated and loose parts of the coating were nailed on or adhered to the surface. The upper side of the existing coating was cleaned and primed prior to the application of the coating sheet. In both cases the result was a stable coating showing no tendency of forming steam bulges or cracks.
  • a self adhesive binder of the composition stated in example 2 was appiied to a glass fibre reinforced film of a ethylene copolymer and of a thickness of 2 mm.
  • the glass fibre reinforcement consisted of a glass fleece which was rolled into the film.
  • the self adhesive binder was applied to the side comprising the glass fleece and in the manner described in example 1. As a result of the application of the binder the glass fibre layer became completely saturated thus bringing the binder into contact with the film itself.
  • the resulting coating sheet material had the following composition:
  • the coating sheet was applied to the upper surface of a roof comprising an insulation layer placed on the supporting construction of the roof the upper surface of the insulation layer being primed prior to the application of the coating sheet.
  • the coating was stable and non-cracking.
