Abstract

The invention belongs to a technical field of building materials, providing self-leveling elastic mortar. The component and weight percentage of the self-leveling elastic mortar are that cement takes 10-35%, quartz sand takes 30-70%, admixture takes 0-10%, polymer emulsion takes 5-25%, water reducing agent takes 0.1-2%, defoamer takes 0.1-1.5% and water takes 0-20%. The film of the mortar of the invention is provided with elasticity and strength, simultaneously, the self-leveling of the mortar is good, which satisfies construction requirements.

Description

Technical field [0001] The invention relates to mortar for construction, in particular to a self-leveling elastic mortar. Background technique [0002] After decades of development, flooring has become a fairly mature industry in developed countries. It has a complete range, including hundreds of products in several series such as epoxy, chlorinated polyolefin, polyurethane, polyurea, etc., integrating protection, decoration, and functions. The application range of the floor ranges from general-purpose industrial plants, corridors, parking lots, shopping malls to highly decorative sports venues, hotel halls, and even high-performance conductive, spark-proof, chemical-resistant and other special floors, and the application surface growing. Since the reform and opening up, the construction of a large number of development zones and industrial plants has stimulated the development of the floor industry. As domestic specialized flooring companies gradually enter the fast lane of deve...
