COMPOSITION OF AN INSULATING MATERIAL AND A METHOD FOR MANIFACTURING ARTICLES MADE OF IT

摘要

The material will find application in the buildings for heat insulation. It is environmentally clean; do not emit harmful substances when it is exposed to direct fire. It is recyclable and has high insulating efficiency. The composition includes the following components (in volume %) : - granulous heat-insulating material (perlite and/or expanded-clay aggregate) : (3 - 73), fibrous material (mineral wool and/or fibers) : (5 - 15), heat-resistant clay : (5 - 20); kaolin : (5 - 15), adhesive : (5 - 10); alumina : (2 - 70). It also comprises light cement (5-50) %. The method includes mixing of the components until a homogenous mass has been obtained. Simultaneously water is added, in the quantity of (5-17) (in volume %). The resulting mass is poured into molds, whereupon it is pressed and dried in a microwave oven. The finished products are taken out.
