Abstract

The invention discloses a self-leveling mortar and a preparation method thereof. The self-leveling mortar comprises the following raw materials in parts by weight: 3-11% of cement; 35%-45% of desulfurized gypsum; 20%-30% of a filler; 1-3% of silica fume; 1%-2% of an amorphous calcium aluminate cement rapid hardening agent; 0.5 to 1% of eucalyptol; 0.2%-0.6% of apiezon grease; 2-4% of calcium propionate; 1-2% of lithium carbonate; 2-4% of titanium dioxide; 1-2% of a thickening agent; 1-2% of a water reducing agent; 2-3% of polyether sulfone; 2-4% of a polyvinyl chloride thermoplastic elastomer;and 1-5% of an additive. The self-leveling mortar is high in breaking strength, high in compressive strength, high in fluidity and high in ground bonding force, and the overall comprehensive performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mortar, in particular to a self-leveling mortar and a preparation method thereof. Background technique [0002] For the existing self-leveling materials, they are mainly used on uneven substrates, so as to make the substrate smoother and smoother, which is conducive to the subsequent construction work. Usually, the application of self-leveling materials is to erect various floor materials, such as wooden floors, tile floors, PVC, etc., for leveling operations. However, for gypsum-based self-leveling materials, it also has obvious shortcomings, mainly reflected in poor water resistance and low strength. also suffered certain obstacles. [0003] Therefore, these shortcomings of gypsum-based self-leveling materials must be continuously improved, so as to make the application space of this material wider. At present, in order to improve the performance of desulfurized gypsum-based self-leveling materials, ...
