[0025]

[0026] Mix the above raw materials in a mixer for 10 minutes to make a dry powder mortar, add an appropriate amount of water and stir to put it into use. The waterproof mortar is tested according to JC / T984-2005. The 7-day impermeability pressure is above 1.5Mpa, and the bonding strength with the cement base surface is above 1.6Mpa. It also has excellent flexibility.

Abstract

The invention belongs to the field of chemistry, and provides a polymer-modified waterproof mortar, which comprises portland cement, graded sand, redispersible emulsion powder, water reducer, water-retaining agent, swelling agent and active filler. In the invention, the redispersible emulsion powder is used for sealing mortar pores after being formed into a film, so as to prevent water from permeating into channels and make mortar have high bonding force and flexibility. The added active filler in the invention can improve the solidity and construction performance of the mortar, and the added swelling agent can counteract part of the dry shrinkage stress of the mortar, optimize the grade of sands and improve the compactness of the mortar. The waterproof mortar, which have high-strength, can be widely used for waterproof construction in walls, toilets, basements, and other places, and has the characteristics of convenient use, wide application range, high durability, long service period and the like.

Description

Technical field: [0001] The invention belongs to the field of chemistry, and in particular relates to a polymer-modified waterproof building material, in particular to a polymer-modified waterproof mortar. Background technique: [0002] Building leakage mainly includes roofs, toilets, balconies, floors, exterior walls, basements, pools, trenches, etc., and has always been a major problem affecting the quality of living. Building waterproof technology can be divided into two categories: rigid waterproof and flexible waterproof according to the physical properties of the materials used. Flexible waterproofing mainly uses polymers as the main carrier, including various coiled materials, coatings, sealants, etc., and is the most important waterproofing measure traditionally. The physical properties of such materials and the main structure of the building are very different, and there are generally unsynchronized service life, Difficulties such as easy separation during use, lea...
