Abstract

The concrete and mortar waterproof agent is prepared with fatty acid 20-40 weight portions, water 60-80 weight portions, emulsifying modifier 0.4-0.6 weight portions, admixture 0.3-0.5 weight portions, and defoaming agent 0.01-0.02 weight portions. The production process includes the steps of dissolving fatty acid in water while heating in furnace; lowering the temperature and adding emulsifying modifier while stirring; adding admixture while stirring and heating; and adding defoaming agent and lowering the temperature. The present invention is used in various waterproof, leakage blocking, anti-seepage and moistureproof engineering.

Description

technical field [0001] The invention relates to a building anti-seepage and water-repellent agent and its production process and construction method. Background technique [0002] In the anti-seepage concrete of buildings, methods such as adding admixtures, adding more cement, and increasing the sand rate are often used to achieve the purpose of anti-seepage. Polyurethane coating film, SBS modified asphalt and other coiled materials are used for double waterproofing. This method requires that the waterproof interface must be flat and dry. advanced questions. [0003] Existing waterproof compositions such as Japanese patent (JP60005054) disperse fatty acids in water, due to the difference in temperature control and temperature control time, the dissolution of fatty acids is not complete enough, and the emulsification reaction is not thorough enough, so that the active ingredients of fatty acids in the waterproofing agent are not enough. , affecting the waterproof effect.
