Preparation method for antistatic cement-based self-levelling surface-layer mortar
The invention provides a preparation method for antistatic cement-based self-levelling surface-layer mortar. The preparation method comprises: selecting high-aluminium cement, aluminium cement, Portland cement, fly ash, desulfurized gypsum, quartz sand, mine tailing sand, carbon fiber, graphite powder, redispersible latex powder, cellulose ether, a water reducer, an antifoaming agent, a rapid-setting early-strength agent and a retarder as raw materials, preparing according to a ratio, and uniformly mixing in a high-speed mixer at a rotation speed of 60-200 r/min for 8-10 min, so as to prepare the antistatic cement-based self-levelling surface-layer mortar. By adding a large amount of fly ash and other industrial waste slag, wastes are changed into valuables, a large amount of source is saved, and considerable social economic benefit is brought. Carbon fiber and graphite powder in the raw materials possess electric conductivity and form a stereo point-line-surface interlaced three-dimensional electric-conduction system in a mortar hydrate through combined usage, and exhaust and release of static electricity are facilitated. Additionally, cast self-levelling surface-layer mortar is flat in surface, also is capable of reducing sound of vehicles rolling ground, and is applicable to ground leveling and decoration of a place needing to prevent static electricity.
