Abstract
The invention relates to a building water repellent. The building water repellent treats fatty acid salt, such as calcium stearate, ammonium stearate, aluminum stearate , calcium oleate, ammonium oleate and aluminum oleate as a main component, and an efficient water reducer or a common water reducer, such as a naphthalene sulfonate-formaldehyde condensate or lignosulfonate is added, so the addition of the water reducer component and the fatty acid salt reduces the water consumption of a cement mortar by above 10%, the strength of the waterproof mortar is substantially improved, the strength reduction caused by the doping of a large amount of stearate is compensated, and the enhancement effect is realized; and the water reduction effect realizes the aperture reduction and coarse aperture refinement of the mortar concrete, and an excellent waterproof effect is possessed, and the coarse aperture refinement obviously improves the problem of the reduced waterproof properties of higher fatty acid water repellents under long-term dipping.
Description
Technical field
The present invention relates to a kind of building material field, is more specifically a kind of waterproof agent for building.
Background technology
The higher fatty acid compounds, as cement waterproof agent generally application in the construction work of developed country, has also been introduced this technology in recent years in China.Soap (metal soap) and higher fatty acid matter himself are exactly the material that water-repellancy is good, and these compounds can make the kapillary water suction in mortar obviously reduce.But the defect of this water-resisting agent is, in the situation that the Long term immersion water-repellancy can reduce, is accompanied by the increase of incorporation, and intensity can reduce.
Goal of the invention
The purpose of this invention is to provide a kind of waterproof agent for building, utilize the combination advantage of several novel materials, improve the pore structure on mortar and concrete, make the water-resisting agent of stearate series in the Long term immersion situation, still keep excellent water-repellancy.
Summary of the invention
A kind of waterproof agent for building of the present invention, take the higher fatty acid salt as main component, has added water reducer, air entrapment agent, and colloidal materials, described higher fatty acid salt is one or more in calcium stearate, ammonium stearate, aluminum stearate, calcium oleate; Described water reducer is bitter edible plant sulfonic formaldehyde condensation compound, one or more in condensate of melamine and formaldehyde or sulfonated lignin, and described air entrapment agent is sodium bentonite, described colloidal materials is polyvinyl alcohol or Vinyl Acetate Copolymer.Wherein the weight ratio of above-mentioned each composition is the higher fatty acid salt: water reducer: air entrapment agent; Colloidal materials=1: 0.05-0.1: 0.001-0.003: 0.001-0.003: 0.05-0.1.
a kind of waterproof agent for building of the present invention is take aliphatic salt as main component, calcium stearate for example, ammonium stearate, aluminum stearate, calcium oleate, ammonium oleate, aluminium oleate, add high efficiency water reducing agent or ordinary water-reducing agent, bitter edible plant sulfonic formaldehyde condensation compound for example, condensate of melamine and formaldehyde or sulfonated lignin etc., the water consumption that can make sand-cement slurry that adds of these diminishing components and soap reduces more than 10%, significantly improve the intensity of waterproof mortar, compensation is owing to mixing outside the strength decreased that a large amount of stearate bring, also has enhancement, water-reduction also makes the hole of mortar concrete reduce, the gross porosity refinement, has more excellent waterproof effect, the gross porosity refinement also make problem that water-repellancy under higher fatty acid class water-resisting agent Long term immersion reduces be improved significantly.
In addition, for further improving the concrete weather resistance of pore character and waterproof mortar, compound appropriate air entrapment agent, introduce a large amount of evenly micro-bubbles, cut off penetrating passage, further improved the leaching problem of fatty acid water-resisting agent, long-term impermeability significantly improves, and the existence of microbubble has also significantly improved mortar and concrete weather resistance.
In addition, for further improving the homogeneity of liquid phase, settlement prevention, allocate a small amount of polyvinyl alcohol or Vinyl Acetate Copolymer into, allocates sodium bentonite into and also can.
