Insulating material and method of its production

Abstract

Abstract An insulating material, especially a non-flammable thermally insulating material containing water glass and a plastic component consisting of a mixture containing 43 to 57.5 weight percent of a plastic component, 30 to 47 weight percent of an aqueous solution of silicate, 9 to 11.5 weight percent of hollow glass microspheres, and 0.1 to 1 weight percent of a water glass stabilizer. Method of production of the insulating material, especially method of production of the non-flammable thermally insulating material lying in the fact that, as the first step, a water glass stabilizer is added into the aqueous solution of silicate and, at the same time, a mixture of phenyl methyl diisocyanate and branched polyol is prepared and then the aqueous solution of silicate is intermixed with the mixture of phenyl methyl diisocyanate and branched polyol and thereafter hollow glass spheres are added into the resulting mixture and everything is then thoroughly mixed again.
