Abstract
A method is provided for the manufacture of elastic, fire resistant, organo-mineral systems based on water-glass in which, to the water-glass, compounds, having terminal amino groups are added, in which at least one free hydrogen atom on at least one amino group and at least one alkylene group interrupted by one oxygen and/or sulphur atom are present as well as the products and the two component systems which can be obtained therewith. The later can be applied in mining for filling and/or agglutination of anchors.
Claims9
A method for the manufacture of elastic, fire resistant organo-mineral systems based on waterglass, which method comprises the steps of:
- (A) providing component A which comprises waterglass and a compound containing terminal amino groups, wherein said compound is a polyoxyalkylene polyamine or mixture of different polyoxyalkylene polyamines,
- (B) providing component B which comprises a polyisocyanate or a polyisocyanate prepolymer,
- (C) mixing component A with component B in the presence of a catalyst for the trimerization of polyisocyanate, and
- (D) allowing the mixture to react and form a gel which can be immediately sprayed overhead without falling down.
