Abstract

The invention discloses waterborne epoxy self-leveling mortar and a preparation method thereof. The water-based epoxy self-leveling mortar is prepared from the following raw materials in percentage by weight: 3 to 7 percent of water-based epoxy emulsion, 2 to 6 percent of water-based epoxy curing agent, 0.01 to 0.1 percent of water-based defoaming agent, 6 to 10 percent of purified water, 40 to 60 percent of quartz sand, 0.1 to 0.3 percent of water reducing agent, 0.1 to 0.3 percent of defoaming agent, 0.2 to 0.65 percent of expanding agent, 0.01 to 0.03 percent of thickening agent and 25 to 35 percent of white cement. The construction process is simple, the construction thickness on a concrete substrate at the temperature of 10-35 DEG C can reach 2 mm, the fluidity is 140 mm or above, the operable time is 25 min, shrinkage is avoided after drying, and the surface fine and smooth effect is good.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-based epoxy self-leveling mortar and a preparation method thereof. Background technique [0002] Cement-based self-leveling mortar for ground is made by mixing cement-based cementitious materials, fine aggregates, fillers, and powder additives. Before use, it needs to add an appropriate amount of water and stir evenly. It has excellent fluidity and can be automatically leveled. ground materials. The material is suitable for floor decoration of industrial plants and homes. Cement-based self-leveling mortar for ground has the advantages of high early strength, good fluidity, easy laying, fast construction speed, short construction period, etc., and has dual functions of bearing and decoration. Self-leveling mortar is safe to use, pollution-free, beautiful, fast construction and put into use are the characteristics of self-leveling cement. It improves the civil...
