  • Radically curing systems are characterized by rapid low-temperature curing (e.g. - 10 ° C), but show a relatively high shrinkage ("shrinkage") and not very high pull-out values.
  • Systems based on epoxy amine show a significantly slower curing rate at low temperatures (e.g. ⁇ + 5 ° C), but have significantly less shrinkage and significantly higher pull-out values.
  • a further object for preferred aspects of the present invention is the provision of a fastening compound in the form of a hybrid system which avoids ingredients that are highly hazardous to health and preferably does not require labeling.
  • DE 40 34279 A1 describes an enamine reaction for the production of crosslinked products for use as a coating.
  • the enamine reaction occurs spontaneously between polyacetoacetates (reaction resin with CH-acidic methylene groups) and polyamines.

  • epoxy resins which can also react with the amines, are additionally present in the curable composition.

  • the excess mortar is removed with a spatula.
  • the threaded rod is pulled until failure while measuring the failure load.
  • the gel time is determined from a 30 g mixture in a plastic beaker at 23 ° C. by means of manual stirring. When the gelation point is reached, the previously liquid mixture becomes highly viscous and gel-like, which is noticeable through the formation of lumps. At this point, the clock started after the test started will be stopped. The gel time can be read off directly.
  • Tg onset or glass transition temperature
  • Example 1 Composition and pull-out tests from concrete of hybrid systems according to the invention (RMA + AMA preferred)
  • the bond stresses listed in Table 2 demonstrate the enormous efficiency of the hybrid system according to the invention. Table 2 also shows the robustness of the hybrid system, since both the primary amine content and the molar ratios between amino groups and acrylate groups can be varied over a wide range without suffering a loss in performance.
  • Example 2 Compositions and pull-out tests from concrete with different primary amines (RMA + AMA preferred)
  • Table 3 shows that all primary amines can be used in the hybrid systems according to the invention.
  • Table 3 also shows that the hybrid systems according to the invention can combine the advantages of the systems previously used in chemical fastening technology: a fast one Curing as with radically curing systems, with the high bond stresses of epoxy systems. This is confirmed by the gel times and bond stresses determined.
  • Example B2.1 is mixed again with half the amount of TMG. The resulting gel time is 07:20 [mm: ss]. This experiment shows that the gel time can be controlled with the aid of the amount of catalyst used and set to a desired gel time.
  • Example 3 Compositions and pull-out tests from concrete of hybrid systems according to the invention (RMA + En preferred)
  • the following table 4 shows the constituents used and the determined composite tensions of hybrid systems according to the invention, in which the amount of primary amines used or the primary amino groups (-NH2) present in the system from them are balanced by CH-acidic methylene groups (-CH2-), whereby the reactions i. and iii. can run preferentially.
  • Table 4 further illustrates the enormous performance of the hybrid systems according to the invention already shown in Table 2, as well as their robustness.
  • Example 4 Pull-out tests from concrete with mixtures of the components a, b and c
  • Example 6 Composition and determination of the onset or glass transition temperatures of hybrid systems according to the invention
  • the glass transition temperature When the glass transition temperature is exceeded, a solid polymer changes to a rubbery to viscous state.
  • the glass transition temperature is a measure of the strength under the influence of heat. Since, depending on the weather, high temperatures can occur on construction sites, the aim is to develop systems with correspondingly high glass transition temperatures. Table 7 below shows the onset or glass transition temperatures of hybrid systems according to the invention in comparison with a standard epoxy-amine system.
  • FIS EM 390 S® (fischerwerke GmbH & Co. KG, Waldachtal, Germany) is a successful, well-established example on the market of a two-component injection mortar system for grouting in anchoring elements based on an epoxy-amine reaction.
  • Table 7 shows that the onset temperatures of the hybrid systems according to the invention are comparable to an established injection mortar system and even exceed this in the second run in terms of the glass transition temperature.
  • the hybrid systems according to the invention accordingly also have the necessary heat resistance, as required under construction site conditions.
