The invention discloses high-performance antistatic self-leveling mortar. The high-performance antistatic self-leveling mortar is prepared from the following raw materials in parts by weight: 55 to 80parts of portland cement, 5 to 10 parts of sulphoaluminate cement, 10 to 15 parts of re-dispersible latex powder, 10 to 13 parts of fly ash, 0.35 to 1.5 parts of polypropylene fiber, 2 to 5 parts ofultrafine ettringite, 0.1 to 0.2 part of a water reducing agent, 0.1 to 0.2 part of an early strength agent, 0.15 to 0.3 part of a retarder, 0.15 to 0.3 part of a thickener, and 50 to 100-mesh waste polystyrene sheet broken particles. The high-performance antistatic self-leveling mortar has good fluidity, self-flow leveling, no need for vibration, simple construction, water addition, pumping pouring, and quick spreading; the mortar is wear-resistant and anti-cracking, smoothing in surface, fast and convenient in construction, has high hardening strength on the ground, excellent antistatic andwaterproof performance, can be made into colored ground of different colors, and is environmentally-friendly easy-to-operate self-leveling mortar.
