Embodiment 1
[0010] A method for making thermal insulation boards from waste foam glass, which is characterized in that foam glass fragments, foam glass powder, cellulose, rubber powder, cement and lime are mixed evenly with water, cast into a rectangular body by using a mold, and cut into pieces after natural drying Plate-shaped recycled material finished product, the weight ratio of the above foam glass fragments is 64%, the block diameter is 30mm-150mm, the weight ratio of foam glass powder is 16%, the weight ratio of cellulose is 0.24%, the weight ratio of rubber powder The weight ratio of cement is 0.12%, the weight ratio of cement is 15%, and the weight ratio of lime is 4.64%.
[0011] Above-mentioned embodiment has adopted the cellular glass fragment of different sizes,

[0013]
Embodiment 2
[0015] Divide the rectangular body poured by the above method into recycled material sheets, place two recycled material sheets on the upper layer and the lower layer, sandwich a layer of non-recycled material sheets in the middle, and glue them together to make a finished composite insulation board. The indicators are shown in Table 2:

Embodiment 3
[0019] Divide the rectangular body poured by the above method into recycled material sheets, place two non-recycled material sheets on the upper layer and the lower layer, sandwich a layer of recycled material sheets in the middle, and bond them with glue to make a finished composite insulation board.
