Embodiment 1
[0038] A foamed lightweight insulation board based on graphene and stone tailings, made of the following components by weight percentage:
[0039] Stone tailings 63%, clay 5%, graphene 5%, calcium carbonate 5%, vermiculite 5%, high temperature co-solvent 5%, expanded graphite 3%, stabilizer 4%, debonding agent 4%, colorant 1 %.
[0040] Among them, the stone tailings are granite; the clay is yellow mud; the high-temperature flux is calcined talc; the stabilizer is yttrium oxide.
[0041] A method for preparing a foamed lightweight insulation board based on graphene and stone tailings, comprising the following steps:
[0042] S1. Raw material preparation: Weigh the materials according to the mass percentage of each raw material, mix them, and use a ball mill to mix and mill them for 10 hours until the fineness reaches 250 mesh and pass through a sieve, and finally put them into the storage bin for mixing and homogenization.
[0043] S2. Spray granulation: the raw materials pr...
