Abstract
A one-component molding material based on polyisocyanato-isocyanurates and flameproofing and fireproofing agents, as well as optionally polyisocyanates, fillers and promoters is described which comprises 40 to 80% by weight of the isocyanurate of 1,6-hexamethylene diisocyanate, 0 to 20% by weight of crude MDI and/or prepolymer of polyol and crude MDI and/or isophorone diisocyanate optinally in combination with further isocyanate groups containing compounds, 5 to 20% by weight of a fireproofing mixture mainly consisting of secondary ammonium phosphate, 0 to 50% by weight filler and 0 to 5% by weight promoter. This low viscosity putty-like mass which is cold-workable and is cured under the influence of moisture, especially at increased temperatures, is useful as construction material for many applications, especially for the manufacture of molded components and plate elements for the construction of land, air and water vehicles. The products obtained after curing meet the highest requirements with regard to fire protection and possess excellent mechanical properties.
