Definitions
- the invention relates to a process for the preparation of a binder, the binder obtainable therefrom, its use and the cured molded articles produced therefrom.
- Sol-gel processes are usually based on the hydrolysis and condensation of alkoxides, usually in conjunction with silanes. These processes have been known for a long time. Details of the sol-gel method are e.g. at CJ. Brinker, G.W. Scherer: "SoI-GeI Science - The Physics and Chemistry of Sol-Gel Processing", Academic Press, Boston, San Diego, New York, Sydney (1990). A variety of compositions have been studied. Orthosilicic esters are e.g. been used for more than 50 years as a binder for refractory products. As early as 1939 Schröder and Geffcken filed patents for the coating of glasses via sol-gel processes.
- sol-gel processes have become known, which have typically focused on thin film applications.
- hybrid materials were developed, in which organoalkoxysilanes were condensed together with alkoxides of other elements, which yielded so-called inorganic-organic hybrid materials.
- Ormosils, Ormocere, Ceramere or Polycerams are examples of organoalkoxysilanes.
- Typical of these compounds is that they use as organo-compound linker the above-mentioned organoalkoxysilanes, since silicon is practically the only inorganic element having a stable silicon-carbon bond at ambient conditions. Through the functionalization of the bond any organic functions can be attached to the silicon.
- the hydrolyzable radicals of the alkoxysilane can be used to build up inorganic networks via hydrolysis and condensation. About the variations of the organic residue can be virtually all functions that are known in organic chemistry, introduce into the condensates. There are countless publications in the literature about this type of hybrid material. Ormocers have also found industrial significance for coating materials on a large scale, z. B. as hard coatings and corrosion protection layers.
- interpenetrating polymeric networks see e.g. Römpp Chemie Lexikon, 9th edition, p. 2007.
- the interpenetrating networks may or may not be covalently linked together. In the latter case, there is a physical mixture.
- the organic polymer chains can be used to change the mechanical properties of the materials. While the pure inorganic bonds lead to brittle materials that require temperatures above the transformation point (in glasses) or above the crystallization temperature (in the case of ceramic materials), hybrid materials can usually be compacted at very low temperatures between 60 and 150 ° C. , While the inorganic materials are very resistant to organic solvents or oils, materials based on organic polymer chains tend to swell or complete dissolution, especially at higher temperatures. Conversely, there are many organic polymers that are very alkali resistant. This means that one can achieve an improvement in alkali resistance by incorporating such polymers into the silicatic networks. However, the fundamental dissolution of the silicatic network by alkali attack or hydrothermal attack can not be avoided.
- the silicon-oxygen-silicon bond is also reversible. While it can be formed by condensation of SiOH groups with elimination of water, it can react back relatively quickly to SiOH groups with cleavage of the bond, especially at high water vapor partial pressures and high temperatures.
- binders mentioned in DE-A-19647368 and DE-A-102004004615 for this application show improved resistance, they decompose in principle also under autoclave conditions of e.g. B. 70 0 C at 70 bar.
- the patent application DE 102005002806.3 describes a process for the preparation of consolidated proppants in which a hydrolyzate or condensate of an organosilane, a hydrolysable silane and a metal compound is used as the consolidating agent. These show a significantly improved hydrolysis and corrosion stability under hydrothermal conditions, a further improvement in stability under the said hydrothermal conditions is desirable and for an application according to DE 102005002806.3 in various cases a prerequisite.
- glasses gain hydrolytic stability by incorporating elements of the third and fourth major groups.
- elements are for example aluminum, zirconium or titanium.
- boron acts in this direction, as well as some di- or trivalent elements, such as.
- Titan is known to have a particularly good effect when titanium is incorporated into the glass structure as a so-called network former.
- the task was then to provide binders which are absolutely stable under the above conditions and show no degradation phenomena.
- the object of the invention has surprisingly been achieved in that the metal- or boron-containing component is added in a corresponding sol or corresponding solution immediately after the hydrolysis of the silicon compounds and the concomitant consumption of molecular water before the hydrolyzed silicon compounds begin to condense and to produce molecular water again in an amount to precipitate TiO 2 or a corresponding other metal oxide.
- the reactive groups of the metal- or boron-containing component will react with resulting hydroxy groups of the silicon compounds without hydrolysis of the metal- or boron-containing component.
- the homogeneous, ie low molecular weight or molecular disperse distribution of metal or boron-containing components in the sol or in the solution allows or prevents the formation of nanoparticulate metal or boron oxides, such as TiO 2 , after the addition of water or kept at the lowest level .
- nanoparticulate metal or boron oxides such as TiO 2
- the proof of the effectiveness of the process according to the invention results from the fact that after this step even the addition of a high excess of water, eg 3 to 4 times the stoichiometric amount, does not lead to any precipitation or formation of crystalline products or particles. This could be demonstrated in the examples of the invention listed below, for example by PCS.
- the invention relates to a process for producing a binder comprising a heterocondensate of silicon compounds and metal or boron compounds in which A) at least one hydrolyzable silicon compound having a non-hydrolyzable polymerizable group as Si component is mixed with water to form a hydrolysis product and then B ) at least one metal or boron compound, wherein the metal is selected from AI, Ga, In, Tl, Ge, Ga, Sn, Pb, Ti, Zr, Hf, Sc, Y and La, is added to the hydrolysis product at a time, which is within 15 seconds to 15 minutes after mixing of the hydrolyzable silicon compounds with the water.
- the metal- or boron-containing binder For the preparation of the metal- or boron-containing binder, at least one silicon compound and at least one metal- or boron-containing, preferably one titanium-containing component are used. In a preferred embodiment may also, an organic matrix, which can be linked via polymerization reactions with the inorganic matrix of silicon compound and metal or boron-containing component are added to the binder. Surprisingly, homogeneous metal- or boron-containing binders which, when used for the production of a shaped article, markedly improve the corrosion resistance of the shaped article obtained are obtained by the process according to the invention. In addition, the compressive strength of the molded body formed with the binder in a further preferred embodiment by using long-chain silicon compounds, such as. As poly (alkoxysilanes) or polyalkylsiloxanes, with reactive end groups, can be improved, resulting in the elasticity of the molding by forming a long-chain inorganic network.

If, for example, hydrolyzable silanes and titanium compounds are hydrolyzed at the same time, separate TiO 2 particles are virtually unavoidably formed so that a large part of the Ti is not incorporated into the condensate that forms. This has the consequence that no homogeneous mixed condensate can form.

- the formation of the heterocondensate can be illustrated schematically as follows, without regard to proportions or distribution, wherein the radicals Rx represent the nonhydrolyzable organic polymerizable group and X the hydrolyzable group as defined in the above formulas:
- the undefined valences in the scheme may mean substituents according to the above formulas, OH groups or oxygen bridges. Covalent bonds within the inorganic framework and, if appropriate, with the added organic components can be built up via the polymerizable group Rx during curing.
- very homogeneous heterocondensates can advantageously be formed in which the heteroatoms are homogeneously distributed in the condensate, ie in a molecular dispersion.
