Problems solved by technology

[0005] At present, there are many types of high molecular polymer waterproof coatings commonly used in the prior art, but their compatibility with the base layer is poor, and there is also a problem of easy aging; there are also some waterproof coatings that contain volatile organic compounds (VOC). It is easy to cause harm to human health, and there are also environmental pollution problems

Abstract

The invention discloses a wall construction method. The wall construction method comprises the following steps: base layer treatment, cement mortar plastering, and super-hydrophobic emulsion painting.A preparation method of super-hydrophobic emulsion comprises the following steps: dropwise adding a modifier into a sodium hydroxide aqueous solution while stirring under the condition of 0-5 DEG C,and stirring and mixing for 10-15 hours under the condition of 10-35 DEG C after the dropwise addition is finished; and adding a silica colloidal solution and stirring uniformly. Compared with the prior art, the super-hydrophobic emulsion is adopted to coat the cement wall surface, so that the water penetration resistance of the cement wall surface is effectively improved; compared with a high-molecular polymer waterproof coating commonly used in an existing wall construction method, the wall construction method is more environmentally friendly, has better compatibility with a base layer, anddoes not have the problems of easy aging and VOC of the high-molecular polymer waterproof coating.

Description

Technical field [0001] The invention belongs to the technical field of building waterproofing, and specifically relates to a wall construction method. Background technique [0002] In addition to the requirements for solid construction, it is also waterproof and moisture-proof. The problem of building leakage has always been one of the important factors to measure the quality of construction projects. [0003] Leakage is a common quality problem in existing projects. If the user discovers leakage during use, if things go on like this, the walls of the building will peel off, moldy and smelly, and cause an indelible psychological shadow on the residents. Long-term leakage in workplaces such as computer rooms and workshops can cause damage to office facilities, failure of precision instruments, and even fires due to electrical short circuits. Leakage not only disrupts people's normal life, work, and production order, but also affects the service life of buildings, causing huge econ...
