Abstract

The invention belongs to the technical field of self-leveling floors, and particularly relates to self-leveling floor mortar and a preparation method thereof. The preparation method comprises the steps of: S1, putting Portland cement, aluminate cement, quartz sand, a defoaming agent and gypsum into a stirrer according to the component proportion to be stirred at a high speed in the stirrer, wherein the stirring time is 60-80 minutes; S2, adding the SBR emulsion, the deionized water and the quick-drying curing agent powder into the reaction kettle, and stirring and mixing for 40-50 minutes at 40-45 DEG C; and S3, adding the mixed liquid obtained in the step S2 into the stirrer in the step S1, and performing high-speed stirring and mixing again for 30-40 minutes to obtain the self-leveling floor mortar. The invention provides self-leveling floor mortar and a preparation method thereof, and aims to solve the problems that the drying and curing time of the self-leveling floor mortar is relatively long and the overall working efficiency of laying is reduced in the laying process of the self-leveling floor mortar.

Description

technical field [0001] The invention belongs to the technical field of self-leveling floors, in particular to a self-leveling floor mortar and a preparation method thereof. Background technique [0002] Mortar refers to the bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) and water. It is also called mortar and mortar. Mortar is made by mixing cementitious materials (cement, lime, clay, etc.) and fine aggregate (sand) with water. Commonly used are cement mortar, mixed mortar (or cement-lime mortar), lime mortar and clay mortar. Self-leveling mortar is a powder product that is uniformly mixed with inorganic gelling materials, aggregates, fillers, redispersible latex powder and a small amount of chemical additives through a certain production process. Excellent fluidity, it can be poured by pumping, and it can be automatically leveled to form a smooth surface after a little pavi...
