Definitions

  • the present invention relates to a method for producing shear-resistant coating systems for steel road slabs with asphalt surfaces using epoxy resins.
  • the object of the invention is to develop a method for producing shear-resistant coating systems for steel roadway slabs with asphalt surfaces, which glued over the whole area without grit scattering ensure a permanent connection between the roadway plates and the asphalt surface.
  • This coating system should be easy and reliable to apply and should be comparable in cost to the previous systems.
  • the steel sheets are preferably cleaned so that they are suitable for the application of anti-corrosion agents, in particular anti-corrosion agents based on epoxy resins.
  • the cleaned steel surfaces should therefore correspond to the standard cleanliness level SA 2 1/2 or F1 according to DIN 55928, part 4.
  • the corrosion protection layer a) made of solvent-free, thermally curable epoxy resin can contain the usual active corrosion protection pigments or fillers. However, this addition can be dispensed with entirely in the process according to the invention. In addition, the application of the corrosion protection layer can even be dispensed with entirely and the adhesive bridge made of solvent-free, elasticized epoxy resin can be applied directly. However, since the application of a corrosion protection layer is usually required by the authorities, the solvent-free, thermally curable epoxy resin layer with or without active corrosion protection pigments or fillers is generally used according to the invention.
  • the adhesive bridge b) made of solvent-free, elasticized epoxy resin is preferably produced from a base resin and an elasticizing component and an elasticizing hardener mixture.
  • a polymer-modified bitumen is preferably also added to the hardener mixture.
  • the adhesive layer c which consists of a solvent-free, two-stage curable epoxy resin.
  • This two-stage hardenable epoxy resin should harden to a walkable layer at temperatures between 5 and 60 ° C and only melt and melt when the hot asphalt is applied Only then crosslink to an elastic layer.
  • This adhesive layer is generally suitable for permanently bonding hardened epoxy resins and hot applied asphalt layers to one another over the entire surface.
  • Such two-stage curable epoxy resins have so far only been used in systems that required good paint properties and high solvent resistance.
  • the films initially created are mostly brittle and adhere poorly to the surface.
  • hot asphalt when hot asphalt is applied, they react in such a way that they melt thermoplastic and only then crosslink to form an elastic layer. They are then able to permanently bond to both the already hardened epoxy layer of the adhesive bridge b) and the asphalt layer.
  • this adhesive layer c penetrates the asphalt layer more or less irregularly and then permanently connects to it. Particularly good and permanent connections are created when the asphalt layer contains a certain proportion of polymer-modified bitumen.
  • the adhesive layer used according to the invention is also able to permanently bind hot-applied poured asphalt or asphalt concrete, even if. these do not contain a fraction of polymer-modified bitumen.
  • the adhesive layer of the solvent-free, two-stage curable epoxy resin used in accordance with the invention is thus able to permanently bond the layers of hardened epoxy resins and asphalt layers, which are inherently incompatible and therefore adhere poorly to one another.
  • the hot asphalt layer d) can of course consist in the usual way of one layer or of several layers, in which case one speaks of a lower protective layer and an upper covering layer.
  • the desired wearing course can be selected as the upper surface layer, which can be easily applied to mastic asphalt or asphalt concrete.
  • the coating systems according to the invention are distinguished by excellent mechanical and thermal stability and can be reliably produced in a particularly simple manner.
  • the corrosion layer a), the adhesive bridge b) and the adhesive layer c) are applied in the usual manner at normal temperatures and harden after only a few hours so that they can be walked on. The next layer can then be applied without any problems. As soon as the adhesive layer c) has been applied and cured for a few hours, the hot asphalt layer can be applied immediately.
  • the corrosion layer made of solvent-free, thermally curable epoxy resin is bonded to the cleaned steel sheets much more firmly than would be possible without thermal aftertreatment.
  • the layer thicknesses in the corrosion protection layer a) are 0 to 200 ⁇ m, preferably 130 to 170 ⁇ m.
  • the layer thickness of the adhesive bridge b) is usually 1000 to 3000 microns. For cost reasons, efforts will be made to choose this layer thickness in the range between 1000 and 1500 ⁇ m.
  • the layer thickness of the adhesive layer c) is generally 150 to 400 ⁇ m, preferably 200 to 300 ⁇ m.
  • the asphalt layers d) are chosen in the usual range between 2 and 10 cm, depending on which one. Stress these asphalt surfaces are to be exposed.
  • All epoxy resin layers a), b) and c) should be applied at temperatures of at least 5 ° C, preferably at least 7 ° C.
  • the relative air humidity should not exceed 85% so that there is no condensation build-up.
  • the second curing stage of the adhesive layer c) begins at 70 to 90 ° C, depending on the composition of the epoxy resin used.
  • the adhesive layer melts thermoplastic and crosslinks to its elastic final state.
  • the corrosion protection layer is thus first applied, with customary two-component epoxy resins mixed with hardener being mixed without solvent and preferably without fillers and active corrosion protection pigments and being applied by spraying, rolling or brushing.
  • customary two-component epoxy resins mixed with hardener being mixed without solvent and preferably without fillers and active corrosion protection pigments and being applied by spraying, rolling or brushing.
  • this layer is recommended to apply this layer with lambskin rollers (short-fiber) or flat brushes in a cloister.
  • This layer can be walked on after 4 to 8 hours of room temperature and can be coated with the next layer, namely adhesive bridge b).
  • This adhesive bridge b) is produced from the epoxy resin component and the hardener and is preferably applied uniformly with a doctor blade.
  • the resin component is preferably produced by mixing a base resin and an elasticizing, low-viscosity resin.
  • Two-stage reacting hardeners or hardener mixtures are preferably used as hardeners, which in turn are preferably blended with polymer-modified bitumen. This addition leads to increased waterproofness, improved flexibility due to the softening effect of the bitumen and improved bondability with the other layers. After approx. 6 to 10 hours this adhesive bridge can be walked on and can be coated with the next layer, namely the adhesive layer c).
  • the adhesive layer c) consists of a two-stage hardenable epoxy resin system and is preferably mixed with a two-stage hardener. Like the corrosion protection layer, this layer can also be applied by spraying or rolling. That has proven itself above all Apply with lambskin rolls. After a minimum of 6 hours and a maximum of 72 hours, the hot asphalt layer is then applied to this layer. If the time between the application of the adhesive layer and the asphalt layer is more than 72 hours, it is advisable to apply another layer of the adhesive layer c).
  • the permanent threshold bending test was also carried out and the test conditions were also tightened by 50% and 100%.
  • the system was fully stable in up to 50% more severe conditions.
  • a crack in the mastic asphalt layer was shown after approximately 500,000 load cycles, ie: the adhesion of the covering to the steel sheet is greater than the internal strength of the mastic asphalt.
  • Testing the system at high and low temperatures showed that the system is flexible, but has no plastic deformation. It absorbs the tension elastically and thus prevents the formation of damage.
