The invention discloses an intumescent water-based fireproof coating and a preparation method thereof. The coating is a water-based, single-component and self-drying product and comprises polyurethane-vinyl acetate-acrylate copolymer emulsion, a modified composite flame retardant, precipitated barium sulfate, mica powder, an auxiliary agent and water. The coating is convenient to construct, low in VOC (volatile organic compounds) emission during coating, low in smoke and free of halogen, and is an environment-friendly substitute of a high-performance solvent type fireproof coating. |
