PLASTIC MATERIAL FOR THE PREPARATION OF GLASS-CERAMIC FOAM, GLASS-CERAMIC FOAM PREPARED FROM THIS MATERIAL AND A METHOD OF PREPARATION OF THIS GLASS-CERAMIC FOAM
The invention relates to a plastic material for preparing porous glass- ceramic foam, wherein this foam is formed by a homogeneous mixture of high- content-silica sand with an average grain size of 200 to 300 pm or by a homogeneous mixture of ground glass with a grain size of up to 400 pm, sodium water glass with a silicate modulus of 1.9 to 3.2 and a low molecular weight organic plasticizer in a mass ratio of 100 : (3 to 10) : (1 to 5). In the case of the use of high-silica-content sand, the sintering of this plastic material produces open-pore glass-ceramic foam which is formed by a porous structure of sintered silica sand grains, has a porosity of 20 to 80 %, a bulk density of 600 to 1600 kg/m3 and a pore size (diameter) of 5 to 650 pm. In the case of the use of ground glass, the sintering of this plastic material produces porous glass-ceramic foam which is formed by a porous structure of sintered glass grains, has a porosity of 25 to 70 %, a bulk density of 900 to 2100 kg/m3 and a pore size (diameter) of 1 to 700 pm. The invention also relates to a method of preparation of this glass-ceramic foam.
