Building wallboard with heat preservation effect

Abstract

The utility model discloses a kind of building wallboards with thermal insulation effect, the utility model includes heat preservation structure, adhesive layer, extruded polystyrene board, aluminium foil composite film, anti-cracking layer and facing layer, heat preservation structure includes the first modified phenolic foam board of setting, the second modified phenolic foam board of a plurality of being placed in the first modified phenolic foam board, screw rod passing through the first modified phenolic foam board and nut being screwed on screw rod, adhesive layer is coated in the right side of first modified phenolic foam board, extruded polystyrene board is bonded in the left side of adhesive layer, aluminium foil composite film is bonded in the left side of extruded polystyrene board, anti-cracking layer is bonded in the left side of aluminium foil composite film, facing layer is bonded in the left side of anti-cracking layer.The utility model can adjust thermal insulation effect according to actual use scene by setting heat preservation structure, extruded polystyrene board and aluminium foil composite film, use range is big, then the attenuation rate of thermal insulation performance can be reduced by breathable waterproof layer and nanometer hydrophobic coating.
