摘要

Multi-component (I) obtained by cross-linking solid bonding agent formed from a first component in the form of at least an inorganic, nano-powder with an average particle size of = 1 mu m, which reacts in the presence of a second component under the release of cross-linked fission products, the second component, which is present in the form of an aqueous liquid and a third component, which stores itself during the cross-linking of the inorganic particles of the first component. Multi-component (I) obtained by cross-linking solid bonding agent formed from a first component in the form of at least an inorganic, nano-powder with an average particle size of = 1 mu m, which reacts in the presence of a second component under the release of cross-linked fission products, the second component, which is present in the form of an aqueous liquid and a third component, which stores itself during the cross-linking of the inorganic particles of the first component into the group of the inorganic particles, without contacting with these, in the form of at least one soft metallic powder with an average particle size of = 10 mu m and a brinell hardness (HB) according to DIN 50351 within the range of 3-39 HB 5/31.2/15 or 6-78 HB 5/62.5/15 or 11-158 HB 5/125/15 or 22-100 HB 2.5/62.5/15, is claimed. Independent claims are included for: (1) a compound system (4) with two structural elements (5a, 5b), connected by a hardened inorganic session layer, where the session layer is prepared by bonding, where the hardened session layer is formed in the form of a frame from cross-linked inorganic nano-particles, the frame surrounds the metallic powder inclusions (3), and the thermal coefficient of expansion of the metallic powder inclusion is greater than the thermal coefficient of expansion of the material of the frame; (2) preparing the compound system by the bonding agent comprising mixing the first component of the bonding agent with the third component, and subsequently mixing with the second component by a chemical cross-linking of the inorganic nano-particles of the first component and introducing under the formation of a flexible space frame (2), and converting the mixture before termination of chemical cross-linking to the inorganic session layer, where the metallic powder inclusions formed by the third component for the accelerated solidification of the bonding agent of the session layer is heated by creating an electromagnetic alternating field; and (3) a process for the releasing a multicomponent bonding agent comprising strongly heating the metallic powder inclusions in the bond by creating an electromagnetic alternating field due to the different thermal expansions of the inorganic space frame and the metallic powder inclusions for mechanical stresses and resulting to a breakup of the inorganic space frame.
