The invention relates to the technical field of building materials, and particularly relates to a heat-insulating flame-retardant building material and a preparation method thereof. The building material comprises the following components in parts by mass: 40-60 parts of artificial light-weight aggregate, 40-60 parts of an inorganic gelling material, 10-20 parts of a nano cement additive, 0.2-1.2 parts of anti-cracking fibers, 0.5-2.5 parts of a defoaming agent, 0.5-2.5 parts of a dispersant, 10-20 parts of water, 6-8 parts of calcium carbonate whiskers, 8-10 parts of magnesium salt whiskers, 0.3-0.8 part of a mortar water retaining agent and 0.2-0.5 part of a water reducing agent. The building material has the beneficial effects that the compressive strength and the flexibility of the building material are improved by adding the calcium carbonate whiskers and the magnesium salt whiskers and further improved by adding the anti-cracking fibers, so that the technical deficiencies that an inorganic heat insulating material is high in hardness and easy to drop are well overcome.
