The invention provides green ecological
foam glass prepared from the following raw materials in parts by weight: 75-80 parts of waste glass
powder, 15-20 parts of shell
powder and 0-5 parts of
coal ash. The green ecological
foam glass is produced by using a production method comprising the steps of 1, respectively crushing and
grinding waste beer bottles and shells, and controlling the
fineness, namely the screen residue of a 0.08mm square hole
sieve, to be lower than 10%; 2, uniformly mixing the waste glass
powder, the shell powder and the
coal ash, placing the mixture into a mould in which alundum powder serving as a separant, calcining at 800-850 DEG C in a high-temperature furnace, preserving the heat for 0.8-1.2 hours, and annealing at the temperature of 500-600 DEG C; and 3, cooling the high-temperature furnace to 180-220 DEG C, taking out the mould, and demolding to obtain the green ecological
foam glass. The foam glass produced by using the waste glass, shells serving as renewable resources and the
coal ash has the advantages of high adsorptivity, bacterium inhibition, nontoxicity, no
combustibility, small heat
conductivity coefficient and energy saving so as to be a novel green ecological heat insulation material.
