Embodiment 1
[0029] A kind of production method of the building external wall fireproof insulation material prepared with slag wool:
[0030] (1) Raw material preparation of slag wool: mix blast furnace slag, basalt, fly ash, magnesium oxide, calcium oxide, wollastonite and melt them into a liquid mixture;
[0031] (2) Fiber preparation: The liquid mixture is continuously flowed into the high-speed rotating centrifugal roller, and the liquid mixture is condensed into filamentous filaments under the action of centrifugal throwing and air cooling, and the filaments are collected and formed under the action of the blower. ;
[0032] (3) Preparation of insulation material raw materials: 59% of slag cotton, 6% of polycrystalline zirconia fiber, 15% of desulfurized gypsum, 10% of fly ash, and 10% of 425# cement prepared in the above steps;
[0033] (4) Preparation of wet forming board: put slag wool into the cotton beating pool and mix it with water at a mass ratio of 1:1.2 to make slag cotton ...
