Stable moldings or plates as a lightweight material, for thermal insulation and for use as fire protection, the process for their preparation, their use, and any equipped building.

摘要

The stable moldings and panels serve as lightweight construction material, for equipping building envelopes with thermal insulation or as a local fire protection measure. They are made on the basis of expanded perlite, from a homogeneous mixture, which then hardens. In particular, such a plate consists of a whipped homogenous mixture having a composition of at least 40% by volume of glazed, surface-closed, air-filled spheres of expanded silica sands having a density of only 50 to 400 grams / liter, so that normally no measures for a hydrophobization are necessary as a result of the closed-cell, uncut perlite. The residual volume consists of a mineral or organic binder, which was added with the addition of a foaming agent, so that the plate as a whole, depending on the specific composition of all components due to the air in the expanded perlites and the air from the foaming agent has a density of between 120kg / m 3 up to 1200 kg / m 3. As insulation boards they are used to create wall structures inside or outside of buildings by the insulation boards (8) are applied to a cleaned, leveled with a plaster and then provided with adhesive mortar inner or outer wall of a building. If necessary, they can be mechanically fixed to the building wall, and then a flush (9) can be applied with reinforcing mesh grid (10) glass-based, and finally applied a top coat, which is optionally provided with a paint.
