BORARMES BIS BORFREIES ANORGANISCHES BINDEMITTELSYSTEM
In order to produce a new binder having short binding and curing times, which can be used to obtain composite materials having a high resistance to water, weather and temperature, while also having as low as possible a content of soluble boron compounds, a binder system is proposed which comprises a binder component formed of alkali silicate and a curing component with amounts of metal silicate hydroxide, metal phosphate hydroxide, metal oxide hydroxide and/or metal hydroxide, wherein the binder system comprises less than 2 wt.% borate, and is formed by at least 90 wt.% of a binder base with the following composition: 60-75 wt.% of at least one powder alkali silicate of molar formula: R2O∙x SiO2, where R = Na or K and 2.0 ≤ x ≤ 3.35, having an ignition loss after tempering for 2 hours at 800 °C in the range 8-22 wt.%, 2.9-18.1 wt.% of at least one aluminium, calcium or magnesium silicate, 1.4-20 wt.% zinc phosphate, 10-11.4 wt.% of at least one compound from the group: magnesium oxide, zinc oxide, magnesium hydroxide and aluminium hydroxide.
