Abstract

The invention provides environment-friendly polymer cement wall waterproof slurry and a preparation method thereof. The slurry comprises a liquid material and a powder material, wherein the mass ratio of the liquid material to the powder material is 1:(3-5); the power material comprises, by weight, 35-40 parts of cement, 35-40 parts of quartz sand, 20-25 parts of ground calcium carbonate, 0.1-0.3 part of lubricating agent and 0.2-0.5 part of water reducing agent; the liquid material comprises, by weight, 0.4-0.6 part of dispersing agent, 44-50 parts of water, 0.2-0.4 part of defoaming agent and 45-55 parts of polymer emulsion, the polymer emulsion comprises pure an acrylic emulsion and a styrene-acrylic emulsion, and the mass ratio of the acrylic emulsion to the styrene-acrylic emulsion is 1:(3-5). The slurry and the preparation method thereof have the advantages that the materials used by the slurry use water as the medium, so that the slurry is a waterborne product; the preparation method is green in process, low in energy consumption and free of environment pollution, does not generate three wastes and satisfies the requirements of environment protection.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly polymer cement wall waterproof slurry and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's real estate industry, the quality of projects, especially the quality of building waterproofing projects, has become increasingly prominent. Many high-rise buildings have water seepage and water leakage on the wall, which has become a hot issue for housing complaints; external wall leakage has become the biggest common problem in new buildings. The erosion of water on the wall, especially the penetration into the wall through cracks, This will cause the corrosion of the steel bars inside the concrete, accelerate the carbonation of the concrete, and seriously affect the service life of the building. According to the survey of relevant departments, the leakage rate of the ext...
