Sheet-like fire protection part (35), which is connected with at least one space-limiting surface part (28), comprises fire protection material based on an inorganic sol, comprising (in wt.%) silicon dioxide (solid content) (25-70), surfactants (0.05-10), polyol (0.01-25), alkali metal oxide (0.05-2), acid (0.05-20), anticorrosion material (0.01-10) and distilled or deionized water, where the composition of the fire protection material is castable during the production and is curable by adding a base. An independent claim is also included for a single stage continuous process for producing the fire protection element, comprising: (i) providing two supply containers (2, 6), of which a first supply container is loaded with the starting materials of the fire protection composition as mentioned above and mixed, and a second supply container is loaded with a basic starting material; (ii) providing two conveying devices for conveying the raw materials from the respective supply containers in to a mixing device (12), where mass of starting materials supplied to the mixing device is predeterminable; (iii) mixing the raw materials from the two storage containers to form a material mixture in the mixing device; (iv) continuous degassing of the material mixture by rotation in a device (22) impinged with vacuum; (v) promoting the degassed material mixture by a further metering device for processing; (vi) processing the degassed material mixture by filling the material mixture into a cavity, where the two plate-like space-limiting surface parts arranged parallel to each other are stretched and are sealed peripherally except for an upwardly directed opening for filling the stretched cavity, and (vii) hardening the material mixture at an elevated temperature of 65-95[deg] C. |
