The invention discloses a fluorescent fireproof fibrofelt preparation method. The fibrofelt comprises the following components by weight percentage: 30%-45% of calcium oxide, 25%-50% of silicon dioxide, 15%-25% of magnesium oxide, 1%-5% of zirconia, 1%-5% of carbon, and 1%-5% of titanium dioxide. The method takes podolite, dolomite, basalt, wollastonite, zircon, carbon black and titanium dioxide as the main raw materials. During centrifugal thread throwing, the method enables fluorescent powder to be attached to the surface of spinning solution through the auxiliary effect of nitrogen, achieves the preparation of fluorescent fireproof fibers, and prepares the fluorescent fireproof fibrofelt through the needling and pressing heat setting. The prepared fibrofelt emits red, blue and green light at night or at a dark place, and is good in biological dissolvability and structural stability.
