Definitions

  • the invention relates to a method for producing an airgel material according to the preamble of claim 1. Furthermore, the invention relates to a formed from an airgel material insulation board and a precursor for the production of an airgel material.
  • Aerogels are increasingly used in building technology as high-insulation materials. Numerous methods for their production are known. With increasing industrialization of these materials since the turn of the millennium, the manufacturing processes used in this process are constantly being simplified. Basically, a distinction is made between water glass (sodium silicate) and alkoxide-based compounds such as tetraethyl orthosilicate (TEOS) and tetramethyl orthosilicate (TMOS) as silicate donors, which decisively influence the further synthesis steps.
  • the hydrophobizing agents or silylation reagents used are mainly hexamethyldisilazane (HMDS), trimethylchlorosilane (TMCS) and hexamethyldisiloxane (HMDSO).
  • the critical step in the production of airgel material is the drying of a wet gel.
  • a supercritical fluid typically lower alcohols or later also CO 2 .
  • solvent drying subcritical drying
  • hydrophobic gels can be produced materials with quasi-identical properties as the supercritically dried aerogels. These were called in the beginning according to the classical definition xerogels, a term which is still used today for solvent-dried aerogels.
  • WO 1998/005591 A1 relates to a production process for organically modified, permanently hydrophobic aerogels.
  • the SiO 2 gel is obtained starting from a water glass solution by means of neutralization formed by acid or after the formation of a silica sol by ion exchange and subsequent base addition.
  • the pH value during gelation is typically in the range between 4 and 8.
  • the wet gel is washed in an organic solvent until the water content is less than 5% and then hydrophobed. Drying under atmospheric pressure by evaporation of the solvent leaves the airgel material as granules back.
  • WO 2012/044052 A2 deals with the preparation of optically transparent and non-transparent SiO 2 aerogels in granular form.
  • a water glass sol is injected into an alcohol phase, which forms in this the gel in the form of granules.
  • the gel is further exchanged with alcohol and rendered hydrophobic by means of a silylation reagent.
  • the gel is dried under atmospheric pressure or reduced pressure.
  • the process makes it possible to produce airgel granules with significantly less time, but a significant disadvantage is the washing with ethanol, which is needed to remove the water from the hydrogel phase.
  • the workup of the water-alcohol mixture requires large amounts of energy, which greatly disadvantages this process for large-scale industrial production.
  • HCl hydrophobization of alkogels in a mixture of hydrophobing agent and hydrophobing catalyst
  • WO2013 / 053951 A1 describes the preparation of silicate aerogels and xerogels starting from an alkoxide-based sol. This is gelled by base addition and aged under reflux in alcohol. The gel is then rendered hydrophobic in a solution of hydrophobing agent, preferably HMDSO, and HCl as a catalyst, also under reflux, and subcritically dried. Various forms of drying are described in detail and their influence on the quality of the resulting materials is explained. As a central point, the composition of the pore liquid before drying is too mention which is a mixture of alcohol and water repellent.
  • a disadvantage of the process according to WO2013 / 053951 A1 is that the hydrophobizing agent and optionally an associated catalyst is added to a solid only after gelation and aging of the gel. Particularly in the case of voluminous batches, the hydrophobizing agent can penetrate the interior of the gel only diffusion-limited, ie gradually, so that the hydrophobing step takes a very long time, corresponding to the material thickness.
  • the object of the invention is to provide an improved process for the production of airgel materials.
  • Other objects are to provide an improved insulation board as well as a ready-to-use precursor product for producing an airgel material.

  • the inventive method allows a much simpler compared to the previously known methods production of silicate airgel materials. Characterized in that the hydrophobicization is an acid-catalyzed process, that is catalyzed by H + and H 3 O + ions, the process running under slightly basic conditions gelling process and the process running under acidic conditions hydrophobizing process may be performed in one and the same organogel time cleanly separated from each other , As a further advantage, the inventive method is characterized by a significantly reduced solvent expense. In particular, with the process according to the invention, it is possible to limit the amount of solvent used to produce an airgel to a maximum of 1 .1 times the gel volume. The prior art typically requires more than 2 times the gel volume of solvents.
