Embodiment Construction

[0017] Composition of building waterproofing agent

[0018]

[0019] The water repellant prepared from the above-mentioned raw materials has the same product quality after freezing and thawing, and is resistant to acid, alkali, alcohol and non-toxicity. After the top layer of the building is treated, it is not easy to fall off and is not affected by the environment, so it has a long service life and can effectively prevent water leakage and seepage on the top layer, and the waterproof performance can reach more than 99%. The invention has the advantages of reasonable formula, low production cost and simple preparation method, and can be widely used for waterproofing, leak-proofing and seepage-proofing of the top layer of buildings, and can also be used for treating hidden dangers of water leakage and seepage in buildings.

Abstract

The present invention provides a safe and non-toxic building waterproof agent, and belongs to the field of building additives. The building waterproof agent of the present invention comprises, by weight, 40-70 parts of an acrylic acid emulsion, 1-5 parts of polyvinyl alcohol amine, 5-10 parts of clay, 5-10 parts of calcium stearate, 2-7 parts of ammonium stearate, 1-5 parts of aluminum stearate, 3-5 parts of calcium fluoride, 1-5 parts of dimethyl silicone oil, 1-2 parts of vinyltrimethoxysilane, 1-2 parts of sodium methyl acryl sulfonate, and 6-20 parts of deionized water. The preparation method comprises: uniformly mixingan an acrylic acid emulsion, polyvinyl alcohol amine, clay, calcium stearate, ammonium stearate, aluminum stearate, calcium fluoride and sodium methyl acryl sulfonate to obtain a mixture, heating to a temperature of 30-50 DEG C, stirring dimethyl silicone oil, vinyltrimethoxysilane and deionized water to obtain a mixed material, and slowly adding the mixed material to the mixture. The building waterproof agent of the present invention has characteristics of inexpensive raw materials, simple preparation method and significant waterproof effect.

Description

technical field [0001] The invention relates to a building waterproofing agent composed of organic matter, which belongs to the admixture of building materials. Background technique [0002] Building waterproofing is an important part of construction engineering. This year, building waterproofing has attracted more and more attention from the country and the people. The development of new waterproof materials is a new topic for construction technicians. The advantage of waterproof material is that it can improve the compactness and impermeability of concrete or mortar, and the cost is low, which basically does not increase the construction cost. Water repellents provide an effective seal against moisture, whether liquid or gaseous, which passes on or near the substrate surface. [0003] Traditional waterproof materials, such as asphalt felt, have disadvantages such as easy aging, short life, difficult construction, and high cost. However, complex parts such as modified as...
