<p>The invention relates to a fire protection element (1 or 1') having a layer structure, a process for manufacturing thereof as well as use of the fire protection element for buildings or equipment in buildings of all kind. The fire protection element (1 or 1') comprises at least two mineral wool layers in the form of slabs (2a, 2b), between which is arranged at least one inorganic material layer (3), which liberates water or carbon dioxide under the influence of heat. The manufacturing process comprises the following steps: a) at least one of two mineral wool slabs (2a, 2b) which are to be joined together is coated on one side with an inorganic fire retardant in a form of an aqueous suspension or paste, whereafter b) the mineral wool slabs (2a, 2b) are pressed against each other so that a layer (5) consisting of the inorganic fire retardant is formed between them whereby the mineral wool slabs are glued together by means of the inorganic fire retardant when it dries up.</p> |
