The invention relates to the technical field of ventilation pipelines, and particularly discloses a magnesium fire-resistant heat-insulation air pipe and a preparation method thereof, and the air pipe comprises an inner pipe and a magnesium fire-resistant composite plate; the magnesium fire-resistant composite board comprises a first magnesium gel layer, a fiber layer and a second magnesium gel layer. The magnesium gel layer I and the magnesium gel layer II are prepared from the following raw materials in parts by weight: 100-120 parts of a magnesium material; 20-30 parts of calcium phosphate; 10 to 20 parts of calcium aluminate; 3-5 parts of diatomite; 3-5 parts of a modifier; 3-5 parts of a foaming stabilizer; 5-10 parts of reinforced fibers; 15 to 30 parts of water; the magnesium material is formed by mixing magnesium chloride and magnesium oxide; the modifier is formed by mixing citric acid, sodium methylene dinaphthalene sulfonate and sodium hexametaphosphate; the fiber layer is prepared from wood chips and glass fibers according to the weight ratio of 1: (4-6). The air pipe provided by the invention has very excellent fire resistance and strength.
