Definitions

  • the invention relates to a multicomponent reaction resin system for use with thread-forming screws, which contains a curable compound which, in particular, contains a free-radically curable compound and an inorganic filler in a first component and a curing agent for the at least one free-radically curable reactive resin and water in a further second component .
  • reaction resin systems are used for fastening fastening elements in boreholes.
  • fasteners for hard substrates such as concrete, masonry and the like
  • fasteners for hard substrates such as concrete, masonry and the like
  • Such fastening elements are set rotating and / or striking, depending on the configuration.
  • a thread-forming screw for screwing into hard surfaces is known from EP 0 623 759 B1, which has a shaft as a base body and a screw head as an engagement means for a setting tool at one end of the shaft.
  • the size of the annular gap between the outer surface of the base body and the borehole wall can vary greatly from fastening point to fastening point.
  • high loads can act on the undercuts created by the thread in the subsurface, which lead to a partial or - in the most extreme case - to a complete failure of the fastening point created.
  • fastening elements have a relatively large length of thread in the subsurface, which, however, requires a great deal of effort to set the corresponding fastening element.
  • Suitable curable compounds such as. B. the two-component mortar based on epoxy known from DE 10002605 A1 or the two-component mortar known from DE 3514031 A1 based on radically hardenable compounds, which are also known to the person skilled in the art as universal mortar, for example, have a high filler content, which results in high viscosity and low shrinkage behavior guaranteed with sufficient internal strength of the hardened mass.
  • Another disadvantage of the solution according to DE 198 20 671 A1 is that the annular gap between the outer surface of the base body and the borehole wall has to be of sufficient size so that curable masses with fillers can also be used in addition to low-viscosity masses. In order to completely fill this annular gap, a large amount of the hardenable compound is required.
  • the cartridge systems known for anchor rods such as those known from EP 0431 302 A2, EP 0432 087 A1, EP 0 312 776 A1 or EP 0638 705 A1, are not suitable for use with self-tapping screws due to the very small annular gap suitable because they either contain too coarse-grained fillers or the cartridges cannot be crushed with conventional thread-forming screws or the cartridges produce particles that are too large even when crushed. Since in this application only a few turns of the screw are possible before the screw is set, rapid mixing of the hardenable mass must be ensured so that it hardens reliably, which has not been possible with the known masses up to now.
  • the inventors have found in the course of development that it is possible, through the use of inorganic fillers which have hydrophilic properties, to provide a system that allows rapid and reliable mixing when using thread-forming screws and clean and safe handling when using With thread-forming screws, the separate individual components have a very low viscosity, but the mass is stable immediately after mixing, i.e. has a correspondingly high viscosity.
  • problems with the storage stability of the component containing the free-radically curable compound occur when the free-radically curable compound has hydrophilic properties, which is the case in particular when the free-radically curable compound has free hydroxyl groups.

  • Reactive thinners liquid or low-viscosity monomers and oligomers, which dilute the reaction resin and thereby give it the viscosity necessary for its application, contain one or more functional groups capable of reacting with the reaction resin and, during polymerization (curing), are predominantly part of the hardened ones Mass (resin matrix) become;
  • Inhibitor a compound capable of inhibiting the polymerisation reaction (hardening), which serves to avoid the polymerisation reaction and thus an undesired premature polymerisation of the reaction resin during storage (in this function often also referred to as a stabilizer) and / or the start of the Delaying the polymerization reaction immediately after the addition of the curing agent; the task of the inhibitor depends on the quantities in which it is used; - “Hardeners” substances that cause or initiate the polymerization (hardening) of the radical hardenable compound, such as the reaction resin;
  • Accelelerator a compound capable of accelerating the polymerization reaction (hardening), which serves to accelerate the formation of radicals, in particular from the hardening agent;
  • Resin component a mixture of the reaction resin and inorganic and / or organic additives (fillers and / or additives), such as an inhibitor and / or an accelerator;
  • Hardener component a mixture of the hardener and inorganic and / or organic additives (fillers and / or additives), such as a phlegmatizer, i.e. stabilizer for the hardener;
  • Fill an organic or inorganic, in particular inorganic compound, which can be passive and / or reactive and / or functional;
  • Passive means that the connection is surrounded unchanged by the hardening resin matrix;
  • Reactive means that the compound polymerizes into the resin matrix and forms an expanded network with the resin components;
  • Finctionat means that the compound is not polymerized into the resin matrix but fulfills a certain function in the formulation;
  • Tro-component reaction resin system a reaction resin system which comprises two components stored separately from one another, generally a resin component and a hardener component, so that the reaction resin does not harden until the two components have been mixed;
