Abstract (en)

[origin: WO2019129398A1] The present invention relates to a method for producing a solid fireproof material. The composition for producing the fireproof material contains at least one sodium silicate and microcapsules provided with propellant gas. The fireproof material is made by inflating the microcapsules or breaking open the polymer material of the casing of the microcapsules, wherein this takes place by means of the thermal action or by adding an agent breaking open the casing of the microcapsules.
