Abstract

The invention discloses nano-modified self-sealing single-component film-forming waterproof mortar, and belongs to the technical field of building materials. The mortar is prepared from the followingraw materials in percentage by mass: 20-30% of ordinary Portland cement, 6-15% of sulphoaluminate cement, 10-25% of quartz sand, 40-50% of redispersible latex powder, 3-8% of nano montmorillonite, 2-6% of calcium powder, 2-4% of sodium silicate, 1-2% of polyacrylamide and 1-4% of an additive. The mortar prepared by the invention can realize rapid film formation and cracking resistance, and realizes a self-closing waterproof repair function.

Description

technical field [0001] The invention relates to a nano-modified self-sealing single-component film-forming waterproof mortar, which belongs to the technical field of building materials. Background technique [0002] Based on the implementation of JC / T 2090-2011 or JC / T 984-2011 standards, polymer cement-based waterproof materials are widely used in indoor kitchens because of their inorganic and organic composite composition characteristics, good water resistance and material matching adaptability. Sanitary decoration waterproof treatment materials. Such materials have won the favor of users and manufacturers for their excellent environmental protection, weather resistance and good matching with decoration materials; home improvement waterproofing is basically inseparable from polymer cement waterproofing materials. Polymer cement waterproof materials are divided into one-component waterproof and two-component waterproof; at present, the single-component polymer cement water...
