The invention discloses a preparation method for a lightweight heat-preserving fireproof sheet material by utilizing hollow glass microspheres. The method comprises the following steps: subjecting a hollow glass microspheres by-product to high-temperature glassification treatment by utilizing a vertical electric furnace at 800 to 1200 DEG C, and sieving out glassified particles with a particle size of more than 2 mm so as to obtain a glassification material of the hollow glass microsphere by-product; mixing 45% to 55% of the glassification material of the hollow glass microsphere by-product, 15% to 25% of cement, 3% to 5% of a waterproof agent, 1% to 2% of an early strength agent, 5% to 10% of cellulose fiber and 15% to 25% of water, and carrying out uniform stirring so as to prepare a slurry; laying a fiber gridding cloth in a mold, and pouring the prepared slurry into the mold; and carrying out demolding and then carrying out curing so as to prepare the lightweight heat-preserving fireproof sheet material provided by the invention. The lightweight heat-preserving fireproof sheet material provided by the invention has the advantages of high utilizability of the hollow glass microsphere by-product, low cost and simple process; and the prepared lightweight heat-preserving fireproof sheet material has the advantages of light volume weight, low thermal conductivity, high compressive strength, A-level fireproofing grade and good social benefits.
