Inorganic Binding Agents for Mineral Wool Heat Insulation

The possibility of replacing the phenol-formaldehyde resins by mineral binders for producing the mineral wool heat insulation is considered. As a mineral binder, it is proposed to use the saponite-containing material (SCM) extracted by the method of electrolytic coagulation from the pulp of the tailing damp of industrial ore-dressing of the Lomonosov Diamond Deposit (Arkhangelsk Oblast). Optimal regimes of mechanical activation of SCM at the planetary ball mill PM-100 for manufacturing the binder for mineral wool heat insulating materials have been selected. The assessment of binding properties of SCM was made by calorimetric investigations, which showed that the specific enthalpy of SCM hydration is comparable with the value of hydration heat of the main clinker mineral (dicalcium silicate). The tests of prototypes of mineral wool heat insulation with the mineral binder show that they have good heat insulation property and are not destroyed under the effect of high temperature, at that, this material is environmentally friendly.
