Definitions

  • the invention relates to composites of mineral bodies, in particular stones, and plastics, such as polyurethanes or epoxy resins. These composites are preferably used for solidification of rock bedding, for example in the attachment of roads and especially in coastal protection.
  • DE 10241293 describes a method for fixing banks, in which the mineral surfaces of the banks, in particular loose stones, are connected with a hydrophobic polyurethane to porous moldings. These composites are characterized by a high strength. Since the stones are not glued together over their entire surface, the composites are porous. As a result, water can penetrate into the composite bodies and thus reduce the energy of the waves.
  • WO 2006/134136 describes a method for producing such composites, in which the stones and the starting components of the plastics are brought into a mixer, mixed there and this mixture is applied at the desired location where the plastic hardens.
  • the problem with this method too is that due to the moisture of the stones, partial foaming of the synthetic material can occur.
  • Another problem is to harden stones with different surface conditions under water. So far, different types of stones (including granites) tend to repel the not yet cured polyurethane layer on its surface under water, so that an adhesion of the stones is not possible.
  • the invention therefore relates to a process for the production of composite bodies of mineral bodies and plastics, wherein the liquid starting components of the plastics are applied to the surface of the mineral body, where they harden into plastic, characterized in that prior to application of or in admixture with the liquid starting components of the plastics is applied to the surface of the mineral body cement.
