Requirement, can be widely applied to external wall external thermal insulation field.
For achieving the above object, the present invention adopts the following technical scheme that with loose type molding styrofoam as substrate, lies against
Have on the equipment of evacuation function, by silica aerogel composite slurry uniform fold on substrate, open vacuum pump and apply
Plus negative pressure, so that silica aerogel composite slurry is penetrated in the gap between substrate granular polystyrene and be full of, removed with scraper plate
Unnecessary silica aerogel composite slurry, through 60 DEG C of maintenances 120 hours or natural curing 42 days, prepared silica aerogel osmosis type
A level fireproof heated board.
The silica aerogel osmosis type a level fireproof heated board that the present invention makes, the long 600-1200mm of plate, plate width 300-600mm,
Thickness of slab 30-90mm.
The silica aerogel osmosis type a level fireproof heated board of the present invention, using silica aerogel composite slurry and loose type
Molding styrofoam makes for primary raw material.Wherein, silica aerogel composite slurry is made up of the raw material of following weight portion:
100 parts of silica aerogel
Portland cement 100-500 part
Polycarboxylate water-reducer 1.0-5.0 part
