Abstract
The invention discloses a special defoaming agent for cement-base self-leveling mortar. The special defoaming agent comprises epoxyethane, epoxypropane, polypropylene glycol, a hydrophobing agent stearate, an emulsifier, a thickener and a filler. The special defoaming agent for cement-base self-leveling mortar is a modified polyether defoaming agent. The special defoaming agent has lower cost, so the price is only one half of the market unit price; the special defoaming agent has favorable defoaming effect; the doping quantity is 0.1 wt% of the self-leveling material; and the gas content in the cement-base self-leveling mortar is less than 2.0%. The special defoaming agent has favorable foam control effect. The special defoaming agent does not have excess bubble escape in the cement self-leveling mortar opening time, and has favorable foam inhibiting property; and the foam inhibiting time can reach 2 hours.
