Definitions

  • the invention relates to a method for producing a flexible coating on building materials, in particular porous surfaces of concrete, stone, masonry or the like, wherein initially an adhesion promoter applied liquid to the surface to be coated and then applied to the actual coating a hot melt adhesive.
  • Both the primer coat with adhesion promoter and any intermediate coatings and the final finish coating usually have to completely dry off or harden, since only then are the manufacturers of such coating systems given guarantees for flexibility and desired adhesive tensile strength.
  • a layer structure can therefore easily take several days to complete and be used as intended.
  • hot melt adhesive harden relatively quickly after application in the plastic hot state and give flexible adhesive layers with little time.
  • JP4108954A2 discloses a device with which bottom coatings based on hotmelt can be produced. While the coating device moves over the floor to be coated, a primer is first applied and subsequently heated together with the substrate, whereupon hotmelt is then applied in granular form and melted from the top side.
  • the disadvantage here is the fact that only in terms of process chemistry precisely matched substances (primer on the one hand and hotmelt other hand) can be used and that the process flow and the temperature and coating speed must also be kept meticulously, which often causes major problems in the construction sector or usually does not lead to satisfactory coatings.
  • Object of the present invention is to improve a method of the type mentioned above so that the mentioned disadvantages are avoided and that in particular in a simple and reliable in the field of construction coatings of the type mentioned can be made with hot melt adhesive.
  • This object is achieved according to the present invention in a method of the type mentioned in that the surface to be coated is wet-wet coated with liquefied hot melt adhesive before the final curing of the bonding agent. It has surprisingly been found in the context of the invention that can be applied to commercial primers or primer immediately wet in wet thermoplastic or reactive hot melts, depending on the material tough flexible coatings that are tailored to the particular requirements arise, the large strains , have high abrasion values and high chemical resistance. With this coating method, it is possible to produce technically flawless coatings of the type mentioned much faster and with considerably less work, whereby the required adhesive pull values have been demonstrably reliably achieved in preliminary tests and in some cases have also been significantly exceeded.
  • the hotmelt can be applied wet in wet with the inventive method without time delay in the primer tion. After the solidification which occurs within a few minutes, the coating can also be loaded as intended.
  • the viscosity can be easily controlled by the temperature, wherein the order of both the primer and the pre-liquefied hot melt adhesive can be done by spraying or as a surface application.
  • the base of the adhesion promoter used comes from the group epoxy or polyurethane, which have proven to be ideal for such purposes.
  • Hot melt adhesives may be hotmelts based on thermoplastic polymers and / or copolymers thereof, such as polyolefin, polyamide, polyester, polyurethane, polyethylene, polypropylene, ethyl vinyl acetate or the like, rubber and / or synthetic Rubber, resins, waxes and the like be used.
  • thermoplastic polymers and / or copolymers thereof such as polyolefin, polyamide, polyester, polyurethane, polyethylene, polypropylene, ethyl vinyl acetate or the like, rubber and / or synthetic Rubber, resins, waxes and the like be used.
  • hot-melt adhesive can be applied to one another, which in each case merge without transition due to the thermal influence of the newly applied layer, and it is particularly preferred if different hot-melt adhesives with different properties are used for the different layers. It can be used for example in a lower layer better on the primed substrate adhering materials and in an overlying layer of more elastic or harder or better resistant to chemicals materials.
  • the hot-melt adhesive is adapted to the respective requirements of the coating before application to the bonding agent by mixing different hot melt adhesive with different properties. Also, it can be provided in a very simple way in advance a hot melt adhesive, which is optimal for the particular application.
  • the hot melt adhesive can be applied in a preferred embodiment of the invention in the form of prefabricated webs, sheets, films or the like by heating in place as a coating, which further simplifies the processing in many cases.
  • the hot melt adhesive can also by applying by heated tools, such as. As a heatable spatula or the like, smoothed, molded or supplemented, which allows the fulfillment of further optical and technical requirements.
  • heated tools such as.
  • the joint width was about 5mm.
  • Coating The coating was carried out with a reactive polyurethane hotmelt (PUR) by spraying, at a temperature of about 140 ° C.
  • PUR reactive polyurethane hotmelt
  • the priming time of the primer was only a few minutes and the application of the hotmelt was then wet in wet.
  • the layer thickness was from zero leaking up to 4mm, whereby the gap was mitveryogllt in a depth of additional 5 mm.
  • the PUR had solidified to such an extent that it could withstand a prescribed load such as committing, driving, first stretching, and the like.
  • the joint was stretched 500 times, at various time intervals, to 15 mm and relaxed again, the coating exhibiting no change.
  • a ring with a diameter of 50 mm and a depth of 5 mm was cut. Thereafter, a metal stamp of 50 mm diameter and at least 20 mm thick was adhered to the test surface. After curing of the adhesive, the metal plate was pulled off with a suitable device perpendicular to the concrete surface until breakage.

Abstract

Pour appliquer un revêtement souple sur des matériaux de construction, on applique tout d'abord un promoteur d'adhésion sous forme liquide sur la surface à revêtir, puis on recouvre cette dernière, humide sur humide, avec un adhésif thermofusible liquéfié, avant le durcissement définitif du promoteur d'adhésion. Il en résulte un procédé d'application de revêtement simple et rapide qui permet d'obtenir des surfaces parfaites même dans le domaine du bâtiment.
