Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1 to 3, the embodiment is a fireproof heat-insulating board, which includes a foamed polystyrene board 1, wherein cement corner protectors 2 are respectively installed at eight corners of the foamed polystyrene board 1, a glass fiber mesh cloth 3 is fixed on an outer wall of the foamed polystyrene board 1 through the cement corner protectors 2, a height between the glass fiber mesh cloth 3 and the foamed polystyrene board 1 is 3cm, a first magnesium oxysulfate cement layer 4 is arranged between the glass fiber mesh cloth 3 and the foamed polystyrene board 1, and a second magnesium oxysulfate cement layer 5 is arranged on an outer wall of the glass fiber mesh cloth 3.
Specifically, in this embodiment the cement angle bead 2 includes three mutually perpendicular's right angle set squares, just the right angle of three set squares is concurrent, the cement angle bead 2 is by magnesium oxysulfate cement integrated into one piece.
Specifically, the thickness of the foamed polystyrene board 1 in this embodiment is 10cm, the thickness of the cement corner protector 2 is 3mm, the thickness of the first magnesium oxysulfate cement layer 4 is 3mm, the thickness of the second magnesium oxysulfate cement layer 5 is in the range of 1mm to 7mm, and preferably, the thickness of the second magnesium oxysulfate cement layer 5 in this embodiment is 2 mm.
Specifically, as shown in fig. 4, the manufacturing method of the present embodiment includes:
firstly, fixing a 3mm thick magnesium oxysulfate cement corner protector 2 at eight top corners of a traditional external wall foamed polystyrene board 1 respectively, and then fixing a macroporous glass fiber mesh cloth at a position 3mm high on the six surfaces of the foamed polystyrene board 1 by a top bracing fixing method through the cement corner protector 2.
Step two, preparing the following waterproof magnesium oxysulfate cement slurry with low curing heat release rate by weight ratio: 19.5% of active magnesium oxide (18-25%), 8% of magnesium sulfate (6-12%), 10% of slag (8-15%), 15% of red brick powder (10-20%), 6% of fly ash (5-10%), 3% of silicon powder (2-5%), 2% of sodium polyphosphate (0.5-3.5%), 1.5% of phosphoric acid (0.5-2%), 4% of silicone-acrylic emulsion (3-6%) and 30% of water (28-35%). Wherein the sodium polyphosphate, the phosphoric acid and the silicone-acrylate emulsion improve the water resistance and weather resistance of the magnesium oxysulfate cement, and the slag, the red brick powder, the fly ash and the silicon powder can reduce the curing heat release rate and the shrinkage rate.
And step three, dipping the foamed polystyrene board 1 coated by the glass fiber grids in the step one into the slurry prepared in the step two to obtain the board attached with the glass fiber reinforced magnesium oxysulfate cement slurry, wherein the glass fiber grids are wrapped by the magnesium oxysulfate cement slurry in the step, and a first magnesium oxysulfate cement layer 4 between the glass fiber grids and the foamed polystyrene board 1 and a second magnesium oxysulfate cement layer 5 coated on the outer wall of the glass fiber grids are formed.
