摘要:
The invention relates to a geopolymer material, a method for producing a geopolymer material, and the use of a geopolymer material. In order to create a geopolymer material that exhibits better adhesion to the substrate and to possibly necessary filler particles and has good mechanical and chemical resistances even at low temperatures, the material contains 10 to 80 wt% of film-forming precursors of a silicic-acid ester and of a soluble metallic salt or several soluble metallic salts of Al, Zr, Ti, Sn, and Ce, 0 to 50 wt% of nanoscale and/or microscale filler particles, 0.5 to 40 wt% of an alkali or alkaline-earth compound, and 0.5 to 50 wt% of organic polymer, wherein the polymer is cross-linked with the precursor by an initiator suitable for the particular polymer. According to the invention, a geopolymer material is created which, due to the organic cross-linking in contrast to traditional geopolymer matrices, has very good adhesion and strength even at a temperature range around 100°C. At temperatures above 200°C, the matrix then goes into a purely inorganic state.
