The invention provides a green environmental-friendly building panel, and a preparation method thereof. The green environmental-friendly building panel comprises following raw materials, by weight, 30to 48 parts of waste glass, 28 to 42 parts of
waste rubber particle, 81 to 98 parts of
fly ash, 50 to 64 parts of diatomite, 28 to 38 parts of
quartz sand, 27 to 43 parts of a
foaming agent, 10 to 20parts of a foam stabilizer, 17 to 25 parts of
polypropylene fiber, 11 to 23 parts of
straw fiber, and 12 to 22 parts of a
wetting agent. The green environmental-friendly building panel is invented based on energy-saving green environmental-friendly
building material ecological development principles, and possesses excellent
green environment friendly effect; waste glass and
waste rubber particleare subjected to
processing polishing and high temperature calcining so as to obtain environmental-friendly light stones, and certain
toughness is achieved; applications of conventional
cement concrete are avoided, recycled
industrial waste fly ash is adopted to replace
cement, and is prepared into foamed concrete in an
air compressor, so that production cost is reduced, it is beneficial for environment protection, and extremely excellent
thermal insulation, water absorbing, heat insulation, and
pressure resistance effects are achieved. The green environmental-friendly building panel can be used in construction of roofing, walls, and floors preferably, and construction of green buildings with better performance.
