The invention discloses acid-alkali-resistant glazed hollow bead thermal-insulation mortar, wherein a layer of urea resin aqueous solution coats the surfaces of glazed hollow beads to form a polymer resin layer with both an enhancement characteristic and a hydrophobic characteristic, thus avoiding the surface defects of the glazed hollow beads due to various reasons, and preventing the adsorption and absorption of the glazed hollow beads for water, and then reducing a water absorption; meanwhile, a layer of modified acrylic fibre powder further covers the polymer resin layer, and then other effective auxiliaries cover the modified acrylic fibre powder, thus remarkably reducing a breakage rate during doping of the glazed hollow beads due to compression and collision, and improving the excellent performances of the glazed hollow beads; the prepared thermal-insulation mortar is resistant to acid-alkali corrosion, excellent in thermal-insulation performance, safe and durable, capable of adequately utilizing carbide slag solid wastes, low in production cost, simple and fast in construction, and good in economic benefits and social benefits.
