[0037] The preparation method of the above-mentioned functional cellular glass with radiation protection and thermal insulation properties comprises the following steps:
[0038] The first step, the preparation of air-dried glass slag
[0039] 1) According to the mass fraction, 30-40% SiO 2 , 20-30% PbO, 8-12% BaO, 5-8% SrO, 1-2% Li 2 O, 3-5% Na 2 O, 3-5% K 2 O, 1~3% CeO 2 , 1~3% Al 2 o 3 , 2~4% ZrO 2 , 3~6% of B 2 o 3 , 5-8% Bi 2 o 3 Mix until the uniformity is greater than 98% to form a batch;
[0040] 2) Evenly add the uniformly mixed batch material into the horseshoe flame kiln that has been heated to 1450-1480°C through the screw feeder and melt for 6-16 hours;
[0041] 3) Let the molten glass pass through the feeding channel and gradually cool down to 1100°C. Then, when the molten glass flows to the homogenizing cylinder, control the height of the homogenizing cylinder to allow the molten glass to pass through the material bowl and flow into the pool below th...

[0048] The first step, the preparation of air-dried glass slag
[0049] 1) By mass fraction, 33% SiO 2 , 28% PbO, 12% BaO, 7% SrO, 1% Li 2 O, 3% Na 2 O, 3% K 2 O, 1% CeO 2 , 1% Al 2 o 3 , 2% ZrO 2 , 3% B 2 o 3 , 6% Bi 2 o3 Mix until the uniformity is greater than 98% to form a batch;
[0050] 2) Add uniformly mixed batch materials through a screw feeder into a horseshoe flame furnace that has been heated to 1450 ° C for 7 hours;
[0051] 3) Let the molten glass pass through the feeding channel and gradually cool down to 1100°C. Then, when the molten glass flows to the homogenizing cylinder, control the height of the homogenizing cylinder to allow the molten glass to pass through the material bowl and flow into the pool below the feeding trough At last, the glass in the pool is fished out, and air-dried to obtain air-dried glass slag;

[0057] The first step, the preparation of air-dried glass slag
[0058] 1) By mass fraction, 39% SiO 2 , 23% PbO, 11% BaO, 6% SrO, 2% Li 2 O, 3% Na 2 O, 4% K 2 O, 2% CeO 2 , 1% Al 2 o 3 , 2% ZrO 2 , 1% B 2 o 3 , 6% Bi 2 o 3 Mix until the uniformity is greater than 98% to form a batch;
[0059] 2) Evenly add the uniformly mixed batch material into the horseshoe flame kiln that has been heated to 1460°C through the screw feeder and melt for 12 hours;
[0060] 3) Let the molten glass pass through the feeding channel and gradually cool down to 1100°C. Then, when the molten glass flows to the homogenizing cylinder, control the height of the homogenizing cylinder to allow the molten glass to pass through the material bowl and flow into the pool below the feeding trough At last, the glass in the pool is fished out, and air-dried to obtain air-dried glass slag;
